A look at some of the world’s most threatened forests

A look at some of the world’s most threatened forests



Author(s): DTE Staff
Unplanned and unrestrained activities for agriculture, industry and urbanisation are ruining our most important ally in nature—the forest
Forests are the Earth’s lungs. They help maintain the water cycle and prevent soil erosion. Forests sustain biodiversity.

Products derived from forests are used in our daily lives. Forest-based industries directly employ 13 million people, according to Food and Agriculture Organization’s (FAO) State of the World’s Forests report, 2014. Informally, they provide livelihood to 41 million people worldwide.

But unplanned and excessive human activities are making forests disappear. According to WWF, we have lost about half of the world’s original forest cover in the last 50 years.

In addition to their role in the lives of communities, forests are needed to store global emissions as carbon sinks, making their protection imperative. A recent study says forests could also help eliminate global hunger.

Here is a look at some of the world’s precious forests and factors that threaten them.

Amazon, the world’s largest forest, is spread over Brazil, Peru, Venezuela and Ecuador, among other countries. It is the site of the biggest projected loss. 

Reports say that more than one-quarter of the region will lose its forests in the next two decades. Cattle ranching and agriculture are among the dominant causes of deforestation of the Amazon. A UNEP report says South America’s total forest area reduced by 90 million hectares from 1990 to 2010.

The Amazon rainforest is also threatened by oil spills in countries like Peru. A study shows that climate variability is causing the forest to lose its ability as a carbon sink.

The Atlantic forest—covering parts of Paraguay, Brazil and Argentina—is one of the richest rain forests in the world, boasting of even richer biodiversity per acre than the Amazon. 

However, the region houses 75 per cent of the Brazilian population which places a lot of pressure on the forests. Deforestation is mainly due to conversion of forest lands into croplands for pasture. According to a UNEP release, the 1960s and 1970s saw rapid deforestation of Brazil’s Atlantic rainforest, Mata Atlantica, to supply wood to saw mills and provide land for cattle grazing. 

Eighty-five per cent of the forest has been lost and the remaining forest areas exists in pockets, says this non-profit.

A local mill planted trees on some 91,000 hectares and reports show that forest area reserved for conservation is now regenerating naturally. 

But the Atlantic forest continues to fight for survival against urbanisation, with large cities like Rio de Janeiro and Sao Paulo in Brazil expanding inward.

Brunei, Indonesia and Malaysia share the Heart of Borneo. It is home to 6 per cent of global diversity. But WWF says over half of these forests have been lost, especially in the last three decades. Only 33 per cent of the lowland rainforest remain. 

Deforestation and degradation are driven by weak governance and a lack of stability. Logging is done to provide for timber, palm, oil, pulp, rubber and mineral industries. WWF says increased human activity has also made the forest easily accessible to illegal wildlife trade.

Deforestation will also make the forest vulnerable to extreme weather events. With fewer trees to control soil erosion, 14 of the island’s 20 rivers that begin from the Borneo forest have the potential to affect several villages downstream.

Mining now threatens to further destroy this forest which is rich in coal, copper, gold, silver and diamonds.

Cerrado, the high-plateau region of Brazil, is the most biologically rich grassland, says Nature.org. Forty-five per cent of all plant species found here are unique to the region. It is also home to 935 species of birds and almost 300 mammals.

But only two per cent of the Cerrado is protected by national parks and conservation areas. The grassland is under threat from cattle ranching and the conversion of forests to make way for soy plantations. Large-scale agriculture has made the region one of the largest producers of soybean, says Nature, but has also degraded soil and water quality.

If the current rate of loss continues, Cerrado’s savannah, woodland and forests will disappear by 2030.

Congo Basin represents 20 per cent of the world’s tropical forests and has the highest biological diversity in Africa. 

It is teeming with variety—rivers, grasslands, swamps and flooded forests. This trans-boundary forest stretches into Cameroon, Central African Republic and Democratic Republic of Congo, among other countries. 
Many areas of the Congo Basin are provided on concession to logging and mining companies, leading to widespread deforestation, says World Wildlife Fund. Palm oil plantations and commercial agriculture operations are also putting forests at risk. 

Political instability and armed conflict in the region have led to refugees depending on forests for fuelwood and charcoal, severely impacting this forest. Illegal wildlife trade and poaching have also increased to a great extent.

These coastal forests are spread over southern Sudan, Kenya and Tanzania. Apart from tropical dry forests, they also contain wetlands. The ecoregion is densely populated, with 200-300 persons per square kilometre, living almost on the fringes of the forest. 

Increasing population has put additional pressure on resources. Much of eastern Africa’s forests are overharvested for timber and fuelwood, illegally logged and converted for livestock and cash crops. 

The coastal forests of Tanzania and Kenya have already been reduced to 10 per cent of their original area.

Sumatra forest is special because some of the rarest animals and plants are found here. It is also the only place in the wild where tigers, rhinos, orangutans and elephants co-exist. 

But Sumatra, especially Riau province, has become the centre of Indonesia’s palm oil production—the industry driving deforestation, even in protected forests and national parks. 

The status of plans by some governments to stabilise and even reverse forest loss remain unclear, leaving tigers, orangutans, rhinos and other wildlife at risk.

Why choosing the right surgeon matters even more than you know

Why choosing the right surgeon matters even more than you know



The proliferation of health care rankings by government agencies in the US and a growing list of private organisations have fed the notion that patients can reliably decide where to get their care by choosing the institution or specialty first (Photo: Thinkstock)

It’s conventional wisdom that there are “good” and “bad” hospitals — and that selecting a good one can protect patients from medical errors
In February 2012, LaVerne Stiles went to Citrus Memorial Hospital near her home in central Florida for what should have been a routine surgery.

The bubbly retired secretary had been in a minor car accident weeks earlier. She didn’t worry much about her sore neck until a scan detected a broken bone.

The operation she needed, a spinal fusion, is done tens of thousands of times a year without incident. Stiles, 71, had a choice of three specially trained surgeons at Citrus Memorial, which was rated among the top 100 nationally for spinal procedures.
She had no way of knowing how much was riding on her decision. The doctor she chose, Constantine Toumbis, had one of the highest rates of complications in the country for spinal fusions. The other two doctors had rates among the lowest for postoperative problems like infections and internal bleeding.

It’s conventional wisdom that there are “good” and “bad” hospitals — and that selecting a good one can protect patients from the kinds of medical errors that injure or kill hundreds of thousands of Americans each year.

But a ProPublica analysis of Medicare data found that, when it comes to elective operations, it is much more important to pick the right surgeon.
Today, we are making public the complication rates of nearly 17,000 surgeons nationwide. Patients will be able to weigh surgeons’ past performance as they make what can be a life-and-death decision. Doctors themselves can see where they stand relative to their peers.

The numbers show that the stark differences that Stiles confronted at Citrus Memorial are commonplace across America. Yet many hospitals don’t track the complication rates of individual surgeons and use that data to force improvements. And neither does the government.

A small share of doctors, 11 per cent, accounted for about 25 per cent of the complications. Hundreds of surgeons across the country had rates double and triple the national average. Every day, surgeons with the highest complication rates in our analysis are performing operations in hospitals nationwide.

Subpar performers work even at academic medical centers considered among the nation’s best.

A surgeon with one of the nation’s highest complication rates for prostate removals in our analysis operates at Baltimore’s Johns Hopkins Hospital, a national powerhouse known for its research on patient safety. He alone had more complications than all 10 of his colleagues combined — though they performed nine times as many of the same procedures.

By contrast, some of the nation’s best results for knee replacements were turned in by a surgeon at a small-town clinic in Alabama who insists on personally handling even the most menial aspects of each patient’s surgery and follow-up care.

ProPublica compared the performance of surgeons by examining five years of Medicare records for eight common elective procedures, including knee and hip replacements, spinal fusions and prostate removals.

To be fair to surgeons, ProPublica’s analysis accounted for factors such as patients’ health and age. We focused only on elective cases because they typically involve healthier patients with the best odds of a smooth recovery.

As would be expected, overall complication rates were relatively low, ranging from 2 per cent to 4 per cent, depending on the type of surgery. But experts who reviewed ProPublica’s results say they strongly suggest that the typical surgeon’s rate can and should be significantly lower.

The evidence: Some 756 surgeons who each did at least 50 operations did not record a single complication in the five years covered by the analysis. Another 1,423 had only one.

The issue of patient safety has been at the forefront of American health care since 1999, when the Institute of Medicine released “To Err Is Human,” a landmark report on the startling frequency of medical errors.

But since then, medical errors haven’t abated — recent studies estimate that at least 200,000 patients a year die in hospitals from preventable errors and complications related to their care, which would make patient harm the nation’s third-leading cause of death. Some say one answer is allowing patients to see surgeons’ track records.

“It’s long overdue,” said Dr Charles Mick, former president of the North American Spine Society, who reviewed ProPublica’s findings.
Many systems are supposed to protect patients from high-risk doctors. But ProPublica’s reporting shows that they often fail to identify problem performers.

The Centers for Medicare and Medicaid Services collects reams of data from hospitals and publishes hospital-wide quality measures. It recently started reporting some data on physician groups that voluntarily provide the information. The agency has plans to eventually publish quality data for individual doctors but it hasn’t done so.
CMS officials say focusing on doctors alone isn’t the answer because hospitals rely on teams of health professionals. Reducing patient harm “requires a focus on the full care team,” said the agency’s chief medical officer, Dr. Patrick Conway. “We believe this approach will help create a system that delivers better-quality care, spends our health care dollars in a smarter way and makes people healthier.”
The data for Toumbis, Stiles’ surgeon, shows that his Medicare patients suffered complications again and again between 2009 and 2013. Some 44 were readmitted to Citrus and another local hospital in the days and weeks after he operated on them, an average of nearly one per month.
Stiles was released the day after Toumbis operated on her neck. Minutes after arriving home, however, she collapsed. She died before the ambulance completed the short trip back to Citrus Memorial.
Toumbis had written in her medical records that the operation went well — no complications and no bleeding. But an autopsy by the local medical examiner found bone fragments, as well as almost two cups of pooled blood from an “extensive hemorrhage” in Stiles’ neck.
The examiner concluded that Stiles’ cause of death was a “complication of surgical procedure.”

Toumbis declined several requests for comment and did not respond to a detailed list of questions. Katie Myers, a spokeswoman for Citrus Memorial, said the hospital would have no comment on Toumbis.
“Our hearts go out to family members when a loved one passes away after surgery,” Myers said, “but sadly it sometimes does occur.”
The contemporary patient-safety movement has focused almost exclusively on systemic causes and solutions for medical errors, taking care not to point fingers at individuals.

“This is not a ‘bad apple’ problem,” the Institute of Medicine’s “To Err is Human” report brief said. “More commonly errors are caused by faulty systems, processes, and conditions that lead people to make mistakes or fail to prevent them.”
This approach has given birth to an array of initiatives to reduce patient harm, virtually all of them aimed at hospitals or teams working inside them. They include using safety checklists for basic procedures, handwashing campaigns and urging medical team members to speak up when they see problems.

Few would dispute the value of these steps. But Medicare and accreditation organizations haven’t required hospitals to comprehensively track patient death rates and complication rates by doctor. Beyond meeting some minimum standards, hospitals are free to decide how much of this information to collect.
As a result, most hospitals’ monitoring of surgeons is “rudimentary,” said Dr. Ana Pujols McKee, chief medical officer of The Joint Commission, the nation’s largest hospital accrediting organization.
Some experts say it’s time to put more emphasis on the role of individual practitioners.

“The idea that it’s all systems and there are no individual performance differences is absurd,” said Dr. Robert Wachter, chief of medical service at the University of California, San Francisco Medical Center and a nationally known expert on patient safety. “A good system has a mechanism to identify poor performers and either make them better or get rid of them.”
ProPublica analyzed 2.3 million hip and knee replacements, spinal fusions, gallbladder removals, prostate resections and prostate removals done between 2009 and 2013 on patients in Medicare, the most comprehensive source of national hospital data publicly available. Medicare pays for two out of every five US hospital stays, and researchers routinely use the program’s data to study the health care system.
Because there are many ways to define a surgical complication, we consulted with two dozen physicians to identify those that are directly related to each of the operations. These include infections, blood clots, misaligned orthopedic devices and uncontrolled bleeding. We then counted only cases in which the patient died in the hospital or had a complication requiring readmission within 30 days.
The American College of Surgeons has said surgeons are responsible for all aspects of their patients’ care, from preoperative examinations to complications that can arise after the operation. Dozens of surgeons and patient safety experts interviewed by ProPublica agreed that surgeons can reasonably be held responsible for complications even if they are not directly at fault.
ProPublica’s analysis has some limitations. Patients covered by private insurance were not included, which in some instances omits a substantial portion of a surgeon’s practice. And our definition of complications does not cover other types of patient harm, such as diagnostic errors or readmissions more than 30 days after an operation.

Still, the five years of data document a costly human toll. About 63,000 Medicare patients suffered serious harm, and 3,405 died after going in for procedures widely seen as straightforward and low risk. Taxpayers paid hospitals $645 million for the readmissions alone.
George Lynch nearly died from complications after a 2013 knee replacement. Lynch opted for a surgeon at New York Methodist Hospital near his home in Brooklyn. He couldn’t have known what ProPublica’s analysis shows: The surgeon, Dr. Henry Tischler, had one of the highest complication rates on knee replacements in New York State.
Lynch contracted multiple postsurgical infections and went into septic shock. He says his family, told he might not survive, came to the hospital to say their final goodbyes.

Tischler did not respond to a request for comment. New York Methodist said in an email that Tischler “sees some of the most challenging cases in the region, and goes to great lengths to ensure that each patient receives the best possible care.”

Lynch eventually recovered, but he now needs another knee replacement. This time, he’s peppering his doctors with questions and said performance data will help guide his choice of a surgeon and a hospital.

“I’d rather be a difficult live patient,” he said, “than a compliant dead patient.”
Few hospitals in America are more highly regarded than Johns Hopkins, which U.S. News & World Report ranked No. 1 in the nation 21 times in a row between 1991 and 2011.

Hopkins is also home to the Armstrong Institute for Patient Safety and Quality, led by Dr. Peter Pronovost, among the best-known and most influential voices in the patient-safety movement.

So it was surprising to discover that, according to ProPublica’s analysis, a surgeon with an unusually high complication rate for prostate removals practices at Johns Hopkins.

Dr Misop Han, an associate professor of urology and oncology at the Johns Hopkins Hospital, did prostate removals on 86 Medicare patients in ProPublica’s analysis between 2009 and 2013. A dozen of them had complications, our analysis showed. Adjusting for his patient mix and other factors, Han’s complication rate was 7.6 per cent.
That was more than double the national average for prostate removals in Medicare and three times higher than the average for other surgeons at Hopkins, who had excellent results overall. Three of Han’s colleagues had complication rates low enough to rank in the best 5 per cent nationwide, ProPublica found.

Han declined to respond to questions about his results. He is generally held in high esteem at Hopkins. Dr. Alan Partin, the chairman of the urology department, said in an email that Han is “one of the best surgeons I know.”

In interviews and emailed statements, officials at Johns Hopkins insisted that by their measures Han’s outcomes were “acceptable” and “do not differ significantly from his peers” at the hospital. “His numbers are all within the expected limits,” said Dr. Redonda Miller, the hospital’s vice president of medical affairs.

The hospital said it tracks surgeons’ performance using a variety of methods, including readmissions to Hopkins for any reason, even those unrelated to surgical procedures.

Hospital officials said a review of Han’s prostate removal procedures between 2009 and 2013 showed his readmission rate for all patients — Medicare and non-Medicare — was 4.7 per cent. According to Hopkins, Han’s readmissions peaked in 2010, when he had 10 in 93 cases, a rate of 10.8 per cent. Hospital officials did not specify his readmission rates for the years that followed, but indicated they had dropped.

By these measures, however, Han’s performance still appears below average. Nationally, typical readmission rates for the type of surgery Han most often performed on Medicare patients are about 3.6 per cent, according to two recent studies.

Hopkins said ProPublica’s assessment of Han was skewed by its reliance on Medicare data, which omits hundreds of Han’s procedures that were paid for by private insurance. The hospital’s data shows that his readmission rate for Medicare patients was 8 per cent, twice that of his non-Medicare patients. The Medicare cases, the hospital said in an email, are “hardly a statistically robust sample.”

But compared to other surgeons in Medicare, Han performed enough operations resulting in complications to conclude with 95 per cent certainty that he was an outlier, ProPublica found.

Hopkins officials acknowledged their overall readmission rate for Han reflected readmissions only to Johns Hopkins. But there were additional instances in which Han’s patients were readmitted to other hospitals — cases that Hopkins would not have counted. ProPublica can’t say how many because Medicare patient-privacy rules bar reporting any count of patients between zero and 11.

In interviews last year, Pronovost praised ProPublica’s approach for calculating surgeons’ complication rates, saying it “advanced the field.”
More recently, though, he blasted our findings. “It would be highly irresponsible to present this to the public in its current form, or to make an example of any surgeon based on faulty data analysis,” he wrote in an email last week.

He criticized our use of hospital readmissions to identify instances when patients had suffered complications after surgery. “A readmission is not necessarily indicative of a complication, let alone a serious one,” he said.

The panel of doctors that helped design ProPublica’s methodology agreed on this point — which is why we only counted readmissions that these experts said were likely related to surgical complications.

Pronovost also said our analysis failed to recognize that some doctors are just more likely to readmit patients as a precautionary measure, even when there isn’t a serious complication.

But that doesn’t seem to explain the Medicare readmissions data for Han, the majority of whose patients typically stayed at least four days and had specific diagnoses of postsurgical complications. Medicare pays for patients to return briefly to the hospital under so-called observation status, but our analysis didn’t count these in tabulating complication rates.

Harvard School of Public Health professor Dr. Thomas Lee, who specializes in how to measure patient outcomes, was one of more than a dozen experts who evaluated ProPublica’s work. The differences between surgeons revealed by the analysis are sound — and important, he said.

“I think the methodology was rigorous and conservative,” Lee said. “I would be surprised if any experienced clinician challenged the basic finding, which is that there is real variation among surgeons.”

The proliferation of health care rankings by government agencies and a growing list of private organizations have fed the notion that patients can reliably decide where to get their care by choosing the institution or specialty first.

Yet Hopkins was one of many top-ranked hospitals where ProPublica found surgeons with problematic track records.
The orthopedic department of St. Joseph Hospital in Orange County, Calif., has been rated one of the top 50 in the country by U.S. News & World Report. Yet one of the surgeons, Dr. Gregory Carlson, had one of the highest complication rates for spinal fusions in the country, ProPublica found.

He said his results could reflect errors in the data submitted to Medicare. There is a “multitude of inaccurate and confusing information that is provided to state and federal organizations,” he said in an email.

The hospital’s chief executive, Steve Moreau, said St. Joseph rigorously tracks and compares the work of individual surgeons, and that it has led to lower complication rates in spinal procedures.

Rank and title do not guarantee results, ProPublica’s analysis shows.

At Chicago’s Weiss Memorial Hospital, the facility’s chairman of surgery, who is also the medical director of its center for orthopedics, had among the nation’s highest complication rates for knee replacement operations. Two dozen of the 219 Medicare patients he operated on between 2009 and 2013 subsequently exhibited complications.

In a statement, the hospital acknowledged it was aware of the complication rate compiled by the chairman, Dr. Henry Finn, “which reflects the complex cases Dr. Finn performs.” Finn added that he’s quick to readmit patients so that minor complications do not become more serious.
He said he was not surprised by the data.

“I’m treating aggressively, and that’s what I’d want done for myself,” he said. “It’s sad for me to hear this information. But I certainly hope it’s put in perspective.”
Helen Keller Memorial is a community hospital that serves The Shoals, a northwest Alabama region best known for swamp rock and rhythm and blues — not the quality of its health care.

On an early morning in May, Dr. Aaron Joiner and Dr. John Young stood in one of Helen Keller’s operating rooms, flanking the left leg of a woman whose worn knee joint they were replacing.

Over the next 46 minutes, they worked quickly, barely speaking. Young cut off part of the femur, and Joiner cauterized a vein to minimize bleeding. Their efficient teamwork helped to minimize the time the incision was open and vulnerable to infection. Joiner closed the wound as Young left the room to dictate notes for the medical record.

Joiner has compiled some of the lowest complication rates in ProPublica’s analysis — he performed 282 knee and hip replacements on Medicare patients with zero complications over five years. His excellence is testament to a larger truth: Many surgical injuries are avoidable.
Even as the medical community has worked to reduce patient harm, it has remained common for surgeons and hospital officials to see a certain number of complications as inevitable. Just random bad luck, like a lightning strike.
“We tend to shrug our shoulders and say this is just a natural part of doing health care,” said Dr. Ashish Jha, a patient safety researcher and professor at the Harvard School of Public Health who provided advice for ProPublica’s analysis. If a certain procedure has a 5 per cent infection rate, doctors and hospitals consider it acceptable as long as they’re at that or below, Jha said.

Yet if complications are like lightning bolts, they tend to keep hitting the same surgeons, while missing others.

Hundreds of doctors compiled records that were spotless. Dr. James Porter of Seattle performed 173 prostate removals without a single complication. Dr. David Black, at Freeman Hospital West in Joplin, Missouri, replaced 171 hips with no complications. In Leawood, Kansas, Dr. Thomas Rasmussen did 348 knee replacements with no complications.

“There’s no such thing as a no-risk surgery,” said Dr. Karen Joynt, a cardiologist and another patient safety researcher from the Harvard School of Public Health, “but some surgeons are able to make elective surgeries in selected patients pretty close.”
Some in the medical community worry that pushing doctors to lower their complication rates will prompt them to cherry pick healthy patients and turn away cases that could hurt their numbers.

Joiner and his partners at the North Alabama Bone & Joint Clinic operate far from America’s health care hubs, without many of the niceties that abound at name-brand academic medical centers.

The Shoals region, along the Tennessee River near the border of Mississippi, is not wealthy. Public health statistics show it has a higher than normal percentage of unhealthy people. About a third of the population in the surrounding counties is obese, and about a third smokes.
“We take all comers,” Joiner said.

The clinic’s surgeons attribute their results, in part, to conducting more than half their procedures in pairs. They sacrifice volume and get paid little or nothing extra to have two surgeons work on a single patient. Each surgeon provides the other with backup — what amounts to real-time peer review.

“I may look at something a little backwards or get turned around,” Joiner said. “It’s nice for one of your partners to say, ‘What the hell you doing? You’re not out huntin’ this morning. You’re doing a knee replacement!’”

Joiner said the clinic’s outcomes also reflect a culture in which the work doesn’t end in the operating room.

In many other practices, it’s typical for surgeons to have physician assistants or nurse practitioners follow up with patients after surgery. Joiner and his colleagues do almost all the follow-up care themselves, personally checking with patients to make sure they know what to do and how to recognize signs of postoperative problems.

“We don’t cut corners,” Joiner said. “We do it the right way every time.”

Historically, this approach hasn’t always been rewarded by the medical payment system. In fact, when patients ended up back at the hospital because of surgical injuries or infections, it was effectively a bonus, generating more billings on top of those for the original procedure.
In recent years, Medicare and some private insurers have introduced initiatives that try to upend these incentives. For example, Medicare can dock payments to hospitals if patients who have elective hip and knee replacements are readmitted at especially high rates, or if medical facilities rank among the bottom 25 per cent for certain hospital-acquired infections and injuries.

Supporters say these changes, while incremental, have spurred hospitals to focus on reducing certain poor outcomes as never before. It’s not yet clear, though, if they will prod doctors to alter their practices, too.

Dr Paul Dworak said he’s too fed up to stick around and find out.

Between 2009 and 2013, ProPublica’s analysis shows, the Edina, Minn., surgeon performed 277 knee replacements on Medicare patients with no complications. He also did 165 hip replacements with one of the lowest complication rates in the nation.

Dworak credited his results partly to spending more time on each patient during surgery, prepping them, making sure their implants were placed properly and closing their incisions himself rather than delegating this to an assistant. After operating, Dworak said he kept patients on medication to prevent blood clots longer than other specialists, even though this meant keeping close tabs on their lab results.

But this cost Dworak. He didn’t get paid for the extra time he invested, and he couldn’t schedule as many operations.

Dworak said such frustrations, coupled with reduced Medicare payments and the stress of meeting his patient safety standards, have prompted him to wind down his surgery practice.

“My results were very good, and other orthopedists in the Twin Cities had horseshit results and made more money,” he said. “The general public never knew what the results were.”
Three years before LaVerne Stiles chose Dr Constantine Toumbis to do her ill-fated spinal fusion surgery, a remarkably similar series of events played out at Citrus Memorial Hospital.

George Bogner, a 43-year-old truck driver, came to Toumbis after worsening neck pain made it impossible to work.

Hours after Toumbis performed Bogner’s spinal fusion in June 2009, Bogner began to thrash in his hospital bed, gasping for air. Inside his neck, more than a quart of blood had pooled, squeezing off his windpipe. He was pronounced dead that night.

A private autopsy arranged by Bogner’s family concluded he had died of surgical complications, but Bogner’s death certificate — signed by Toumbis himself — listed the cause as “natural” and mentioned nothing about internal bleeding.

It was the kind of case that should have triggered action from multiple systems designed to monitor doctors’ practices, both inside the hospital and beyond its doors.

That’s not what happened.

Like all hospitals, Citrus Memorial has a peer review panel made up of doctors tasked with examining cases where the care came under question or drew complaints or lawsuits.

Bogner’s case was referred to the committee, a standard practice when a patient died, according to a former hospital employee. The committee never investigated, even though Bogner’s estranged wife later sued Citrus Memorial and was paid a settlement. Toumbis was not named in the lawsuit.

The gaps in Citrus Memorial’s safety net are common at hospitals across the country, experts say. Facilities routinely fail to identify the kind of outliers spotlighted by ProPublica’s analysis or to intervene when such doctors are flagged.

Peer review panels, long the chief mechanism for physician accountability in hospitals, are a prime example. Such committees have an array of tools to help doctors improve, from sending them for more training to compelling that they be coached by colleagues.

In egregious cases, peer review committees can recommend that hospitals suspend or withdraw a doctor’s privileges. Yet there’s evidence that hospitals are doing so less and less.
Hospitals are required to report such sanctions to the National Practitioner Data Bank, a federal clearinghouse of doctor discipline used by health care employers. Reports dropped by more than 20 per cent between 2004 and 2013. A quarter of American hospitals — 890 facilities — have not reported a single disciplinary action in the past 25 years.

“Physicians haven’t gotten that much better!” Robert Oshel, who spent 15 years handling research and disputes at the data bank until he retired in 2008, wrote in an email. Oshel volunteers as a data analyst for Public Citizen, a consumer advocacy group. “Peer review is not effectively protecting patients from incompetent and miscreant physicians.”

Toumbis, 49, had privileges at another Florida hospital, Seven Rivers Regional Medical Center, as well as at Citrus Memorial.

Toumbis performed 316 spinal procedures on Medicare patients at Seven Rivers between 2009 and 2013 and another 247 at Citrus, records show. ProPublica found 23 cases in which Toumbis patients suffered postoperative infections or injuries after operations at Seven Rivers and 21 who were readmitted after procedures at Citrus. That doesn’t include Bogner, not a Medicare patient, or Stiles, who died before she could be readmitted.

Asked about Toumbis, officials at Seven Rivers said the hospital had a “steadfast commitment to quality care and improvement” and that many of the readmissions flagged by ProPublica involved patients who had prior back surgeries or complex medical histories. Officials said the hospital regularly reviews readmissions, but they declined to further discuss Toumbis’ cases.

Colleagues at Citrus were aware that Toumbis had issues. ProPublica interviewed more than a dozen doctors, nurses, physical therapists and other hospital employees familiar with Toumbis’ work. All said it was known that his patients experienced a high rate of complications.

There was also a troubling incident in his past. When Toumbis was in medical school, he stabbed a classmate in the neck after an altercation at a bar. He was convicted of assault, a felony, but was still able to get a medical license.

Three people who sat on Citrus Memorial’s peer review committee for years said they couldn’t recall a single instance in which it did anything tougher than send doctors letters of inquiry.

The panel is called the Performance Improvement Committee — PIC for short. The dark joke among some hospital insiders was that “PIC” actually stood for “Protect, Ignore and Cover Up.”

Ryan Beaty, Citrus Memorial’s chief executive for 10 years until he retired in 2014, said the leaders of the medical staff seemed uncomfortable with policing fellow doctors. “They’re reviewing themselves,” Beaty said. With such leadership, “the process is not going to be as effective as it should be.”

It’s not clear if the PIC looked closely at any of the cases identified by ProPublica in which patients that Toumbis operated on at Citrus Memorial suffered complications.
In about 2010, a hospital official (not a doctor) presented the PIC with information showing that a number of Toumbis’ patients had suffered tears to the dura, the membrane that envelops the spinal cord, during fusion surgeries. Such tears can be serious and should not be common complications.

The committee declined to analyze the cases further, deeming them unfortunate but acceptable side effects of the surgery, a former hospital official said.

The PIC also didn’t substantively investigate Stiles’ death from postsurgical bleeding in 2012, two former hospital officials said.

Peer review is often undermined by the personal and financial ties that bind doctors together, according to experts and a 2008 study.

Toumbis was among the most powerful physicians at Citrus Memorial. He served last year as the chief of staff and, in November, was named to the hospital’s board of trustees. He also rings the cash register: Between 2009 and 2013, Medicare paid the hospital $9 million for cases in which he is listed as the operating physician.

Even when hospitals identify problems with doctors’ competency or practices, they can face formidable hurdles in imposing discipline. Doctors have extensive due process rights that can mire even clear-cut cases in layers of mandatory notifications, hearings and appeals.

In early 2013, it looked as if Toumbis’ pattern of problems might finally draw serious scrutiny. Prompted by reports that his patients were suffering high complication rates, Citrus administrators initiated a review of cases handled by Toumbis and two colleagues who also did spinal fusions.
According to a former hospital official, they found that Toumbis had a higher complication rate than his peers but concluded that his results were acceptable when compared with what little national data was available. No action was taken. The hospital declined to respond to questions about the review or its outcome.
Today, Toumbis remains a busy member of Citrus Memorial’s staff — in fact, he’s now the hospital’s only spinal surgeon.
In a January report called “Shining a Light,” the National Patient Safety Foundation defined four levels of transparency in health care: between clinicians and patients; between clinicians within an organization; between multiple health care organizations; and between providers and the public.

The report endorsed all four, calling transparency the most effective, inexpensive and underutilized tool for improving the quality of care.

In the few instances where such an approach has been tried, there’s powerful evidence that it works.

After New York started publishing individual surgeons’ mortality rates for heart bypass procedures, the state’s overall mortality rates for bypass surgery dropped dramatically, studies showed. Some surgeons with poor results stopped operating or left New York. Hospitals upgraded their protocols to ensure best practices.

Yet overall, the U.S. health care system still provides little transparency about the varying performance of doctors.

In part, this is because doctors have resisted it. In 1979, the American Medical Association sued to bar the disclosure of how much individual physicians were paid by Medicare. The group won a court ruling that stood until 2013 and made it virtually impossible to publish doctor-specific data.

Even now, the government mostly leaves it to others to provide the public with quality-of-care data about doctors. CMS’ Physician Compare website, which is supposed to help patients choose providers, gives information on doctors’ specialties, location and gender — but nothing on how their patients fare.
A few hospitals have introduced programs that suggest the transforming effect greater transparency could have were it embraced more broadly.
On a wintry day in January, officials at Beaumont Hospital, Royal Oak, outside Detroit, convened a predawn meeting of the surgeons, residents, nurses and physician assistants who make up the orthopedics staff.

Beaumont comprehensively tracks complication rates and other quality measures by doctor. Surgeons in the orthopedic department had grown accustomed to receiving their own results and anonymized data for their colleagues.

But at this gathering, department leaders unveiled each surgeon’s performance metrics for the previous year on a giant screen at the front of the room. Dr Lige Kaplan, one of the surgeons, compared it to being at school and having your report card shared with all your classmates.
There was undeniable power in putting the information out there, where everyone could see it.

“When you get that grade, if you don’t like that grade or think you can do better,” Kaplan said, “you either study harder or go to the teacher and ask, ‘What can I do better?’”

Several factors led Beaumont, which has more than 1,000 beds and is well known for orthopedics, to start tracking and sharing doctor-specific data.

The hospital had hired Dr. Samuel Flanders to be the health system’s chief quality and safety officer. Flanders considered tracking doctors’ results one component of a systemic, data-driven quality improvement program.

Hospital leaders saw Medicare had begun introducing payment incentives and penalties to reduce patient harm and knew this would continue. Also, the hospital became part of a Blue Cross Blue Shield of Michigan initiative that pays facilities to compile and share surgical quality data.

Mainly, though, the orthopedics department’s results were not as good as the hospital wanted them to be. ProPublica’s analysis shows that some surgeons at Beaumont had high complication rates for the procedures we examined in Medicare. Beaumont declined to supply its internal quality data, but said its numbers paralleled ProPublica’s.

Once Beaumont’s orthopedics department started tracking data by doctor, certain statistics jumped out immediately.

For example, too many patients were receiving blood transfusions. This can put patients at higher risk for complications.

Tracking data also showed that some of Beaumont’s orthopedic surgeons had unusually high infection rates. Guidelines say patients getting knee replacements should receive antibiotics an hour or two before surgery to fend off such complications. Beaumont found that surgeons were ordering antibiotics haphazardly, some so late that patients still hadn’t received the drugs when they were about to be wheeled into the operating room.

The hospital changed its practices to fix these issues and more, using the data as a road map.

Collectively, the changes brought about a dramatic improvement in surgeons’ results, hospital officials said. Indeed, ProPublica’s data shows that between 2010 and 2013, the hospital cut its complication rate on knee replacements in half.
The meeting in January tapped into doctors’ competitive side.

“It gives the individuals a little extra incentive to look better,” said Dr. James Verner, one of the surgeons there that day. “We’re all competitive in our own way.”
Kaplan, one of the better-performing surgeons at Beaumont in ProPublica’s analysis, said two colleagues approached him afterward to ask how they could improve their transfusion rates.

Beaumont’s orthopedics department has continued to meet quarterly, putting each surgeon’s stats up on the big screen. At the April meeting, the group was eager to see whether there had been improvements, said Dr. Jeffrey Fischgrund, the department’s chairman and a spine surgeon.

“At the January meeting, it was, ‘Why are we doing this?’ ” Fischgrund said. “At the April meeting, it was, ‘Did we make a difference? Is this worth it?’ ”

Sure enough, the group found out there had been a drastic reduction in transfusion rates compared with the previous three months. “You can influence physician behavior through the open discussion of data,” Fischgrund said.

Despite these gains, some of Beaumont’s surgeons said they remain opposed to making individual performance data public.

Verner said patients might blame surgeons for complications that weren’t their fault and surgeons might avoid higher-risk cases that could damage their complication rates.

“I’d rather work to improve someone than publicly shame them,” Fischgrund said. “It’s not that you want to get rid of the outliers, you want to shift the whole curve.”

Some patient safety advocates say it’s not enough for hospitals to share doctors’ track records internally yet withhold this information from patients.

“If you leave it up to altruism of hospitals, you end up with what we have now — just a few that use meaningful data to improve quality,” said Dr. Marty Makary, a surgeon and professor at the Johns Hopkins University School of Medicine. “Broader transparency, if done fairly and accurately, can drive this improvement with greater force.

‘China’s INDCs, although ambitious, will not keep temperature rise below 2 degree celsius’

‘China’s INDCs, although ambitious, will not keep temperature rise below 2 degree celsius’

Although it is doing more than the US and EU, China’s total emissions in 2030 will still be very high, says non-profit Centre for Science and Environment
In a major development, China, the world’s largest greenhouse gas (GHG) emitter, has submitted its Intended Nationally Determined Contributions (INDCs) to the UN Framework Convention on Climate Change (UNFCCC). INDCs are the voluntary pledges that countries are making ahead of the big climate change meeting in Paris at the end of the year to cut carbon pollution. The Paris climate meeting is supposed to come out with a new global deal to tackle climate change from 2020 onwards.
In its INDCs, China has pledged to peak its carbon emissions latest by 2030 and then start reducing it. It has pledged to reduce emissions intensity of its GDP by 60-65 per cent, compared with 2005 levels by 2030. It has also agreed to raise the share of non-fossil fuels to 20 per cent of its primary energy mix by 2030 and increase the forest stock volume by around 4.5 billion cubic meters on the 2005 level by 2030.
China more ambitious than the US and EU
According to the estimations done by the Delhi-based non-profit Centre for Science and Environment (CSE), China’s INDCs are more elaborate and ambitious than the ones put out by United States of America (USA) and European Union (EU). China will have 30 per cent lower GHG emissions – about 6.5 billion tonnes less – than the Business as Usual (BAU) Scenario in 2030. In comparison, the US will cut its emissions only about two billion tonnes per year in 2030 from its BAU scenario.
“In BAU scenario, China would have emitted 22 billion tonnes of carbon pollution in 2030, but now it will emit about 16-17 billion tonnes. This is a significant reduction,” says Chandra Bhushan, Deputy Director General, CSE.
China has also pledged to install 200 gigawatts of wind power and 100 gigawatts of solar power by 2020. These are many more times of what the US plans to install during this period.
China could have done more
CSE’s analysis, however, also points to the fact the INDCs of China are less ambitious compared to what China had pledged to do till 2020 under the Cancun agreement. Under the Cancun Agreement of 2010, China had pledged to reduce emissions intensity of its GDP by 40-45 per cent by 2020 (as compared to those in 2005). Now, it has pledged to reduce emissions intensity of its GDP by 60-65 per cent by 2030 (as compared to those in 2005). So, China will be reducing the emissions intensity of its GDP by less than half the rate during 2020-2030 period, if compared to 2010-2020 period, says the CSE analysis.
China had pledged to have 15 per cent non-fossil fuel in its energy mix by 2020. Now it has pledged to raise the share of non-fossil fuels to 20 per cent of its primary energy mix by 2030. So, an increase of mere 5 per cent from 2020 to 2030 is not exactly “ambitious”.
Although it is doing more than the US and EU, China’s total emissions in 2030 will still be very high. It will be about four times more than India’s. China’s per capita emissions in 2030 will be about 12 tonnes, similar to the US, but again four times higher than India. “Such large emissions are not in line with keeping the global temperature rise within manageable limits,” says Bhushan.
Towards 4-5°C temperature rise
With the announcements of INDCs by China, the US and the EU – the top three polluters – it is now clear that the INDCs will not add up to limit global temperature rise by 2 degrees Celsius. The recently released report of the IPCC mentions that the world needs to cut its emissions between 40 and 70 per cent below 2010 levels by 2050 to stay within the 2 degrees Celsius temperature increase pathway. The INDCs put out so far will not allow the world to meet this benchmark.
“From our analysis, it is quite clear that the Paris deal, like the Copenhagen Accord in 2009, is likely to keep the world to a temperature increase trajectory of four to five degrees Celsius,” says Bhushan.
Reality check for India
The world is now eagerly waiting for India’s INDCs. The big question is what stance India will take. Will it follow the likes of US and China or carve out a different path for itself?
CSE experts believe that India should now work harder with developing countries and push for an ambitious global deal which is fair and equitable and saves the world from catastrophic climate impacts. “India should put out INDCs that are based on equity and fairness. This is the only way we shame big polluters to reduce their emissions which are in line with the planetary limits,” says Sunita Narain, Director General, CSE.
CSE experts have recommended to the government that India should put out two kinds of INDCs:
1. Unconditional INDCs: Under this, India should agree to do all it can with its own resources. These INDCs should be based on principles of equity. The government has already announced ambitious solar and wind energy targets. Under Green India Mission, the government has also pledged to increase forest/tree cover to the extent of 5 million hectares (mha) and improve the quality of forest/tree cover on another 5 mha of forest/non-forest lands. It should also announce targets to reduce emissions intensity of GDP by 2030. Under the Cancun Agreement, India had pledged to reduce the emissions intensity of GDP by 20-25 per cent from 2005 levels by 2020. CSE experts believe that reducing the emissions intensity by 40 per cent by 2030 compared to the 2005 levels is achievable. All these are co-benefit agenda as they would reduce energy consumption, reduce air and water pollution, reduce import bill of the fossil fuels and improve environment quality.
2. Conditional INDCs: Under this, India should pledge to do more than what is demanded by the principle of equity, provided developed countries give finance and technology support to India. CSE experts believe that under this, India can double or even triple its targets for renewable energy, set up a programme for super-efficient appliances, set targets for public transport and electric vehicles, double its target for afforestation, pledge to reduce emissions intensity of its GDP by 60 per cent by 2030, and a few other measures. “All these will move Indian economy decisively towards low carbon growth path which will pave the way for more sustainable and equitable development in the country,” adds Narain.

European Union has unveiled a US $ 96 billion package of funds to support disaster risk management across Sub-Saharan Africa. The fund was declared at the third International Conference on Financing for Development, held in Ethiopia. 

“This is a really excellent initiative. It’s quite unique, and I really hope that we will see many more like it,” said Margareta Wahlström, special representative of the United Nations Secretary-General for Disaster Risk Reduction.

Experts hope that the money will support Africa’s drive to reach the targets for substantial reductions in disaster losses – both human and economic. “Natural hazards cannot be avoided. However, long-term management of risks, in the context of a fast-changing climate, can save lives and livelihoods and set the foundations for sustainable development,” said Roberto Ridolfi, director for sustainable growth and development at the European Commission’s Directorate General for Development and Cooperation.

According to a report by the United Nations’ Office for Disaster reduction, total direct disaster losses in 40 of the globe’s low and middle income countries amounted to US $305 billion over the last 30 years. In Africa alone, from 1990 to 2012, an average of 152 disasters were recorded per year, the majority triggered by floods and storms. In 2014, over 6.8 million African were affected directly by a total of 114 recorded disasters.

World’s largest steel maker to use rabbit microbe to turn emissions into fuel



Author(s): DTE Staff

The project will annually produce fuel that is enough to run half a million cars
In a first for the industry, steel giant ArcelorMittal will use a microbe obtained from a rabbit to convert waste gases produced during steel making into a fuel that can run cars. For this, the multinational, owned by India-born Lakshmi Mittal, plans to spend about US $96 million.
To execute the project, ArcelorMittal has teamed up with LanzaTech, the carbon recycling company, and Primetals Technologies, a leading technology provider. The technology will use a microbe originally found in a rabbit’s gut to create bioethanol from waste gases produced during the steelmaking process.
The project that will be located in the multinational’s Ghent plant in Belgium is being seen as a double-edged sword that will reduce carbon emissions significantly and produce fuel enough to run half a million cars annually. The project. “This partnership is an example of how we are looking at all potential opportunities to reduce CO2 emissions and support a transition to a lower carbon economy,” said Carl De Maré, vice president, innovation, ArcelorMittal.

Fast melting sea ice and rising surface temperatures may draw fish farther north, experts feel
Arctic nations signed an agreement recently to bar fishing fleets from entering the seas around the North Pole.
The treaty signed by the United States, Russia and others can be considered a measure to fight global warming, as sea ice in the Central Arctic Ocean is vanishing fast.
A report on global climate released by the National Oceanic and Atmospheric Administration and the American Meteorological Society says that ocean surface temperatures have reached the highest levels in 135 years.
It is likely that the central region of the Arctic has no commercial fish stocks, according to experts. Fast melting sea ice and rising surface temperatures may draw fish farther north.
Fishing regulation
“Climate change is affecting the migration patterns of fish stocks,” Norwegian foreign minister Boerge Brende said in a statement after the declaration was signed in Oslo, Norway. He added that the Arctic countries had a responsibility to protect the international waters.
According to Brende, Norway, Canada, Denmark, Russia and the United States had a responsibility to regulate fishing in the Arctic. The Arctic nations also want China, Vietnam, South Korea and all European Union countries to agree not to venture into the Central Arctic Ocean.
“It’s a new ocean emerging,” said Scott Highleyman, director of international Arctic affairs at the Pew Charitable Trusts environmental group. “It’s hugely encouraging–it’s hard to get governments’ attention for problems that haven’t occurred yet.”
However, the agreement was an interim one and the nations pledged to begin “a broader process” to regulate commercial fishing in the Arctic Ocean.
Activist reaction
Greenpeace Arctic campaigner Sophie Allain said the agreement should have gone further. “With this agreement, the Arctic States have recognised that the Arctic Ocean is an extraordinary environment which requires far better scientific understanding. But sadly they have missed the chance to deliver the permanent protection this area desperately needs. This region should be declared a marine sanctuary, where all extractive practices, including oil production, are banned.”
One good thing is that the agreement does not prohibit fishing in territorial waters as it is an important source of livelihood for indigenous populations across the Arctic. Melting ice in the region is also opening the region to oil and gas exploration as well as shipping.
