Physicians often have negative attitudes regarding obesity, and many express dissatisfaction about caring for obese patients. Meanwhile, obese patients often feel their physicians are disrespectful or biased against them because of their appearance.  Such observations raise concern that obese patients may receive lower quality care than non-obese patients.
 
Thankfully however, a recent study by Virginia Chang and colleagues from the University of Pennsylvania has shown that medical care for obese patients is at least as good, and in some instances marginally better than that provided to other patients.

To reach these conclusions, Chang’s group compared physicians’ performance on 8 common outpatient quality measures for obese vs. non-obese patients. The study population included 36,122 patients from the Medicare Beneficiary Survey (1994-2006) and 33,500 patients from the Veterans Health Administration (2003-2004).

The scientists tracked performance for diabetes care (eye examination, glycated hemoglobin testing and lipid screening), pneumococcal vaccination, influenza vaccination, screening mammography, colorectal cancer screening, and cervical cancer screening. Data were obtained from administrative claims, survey data and chart review.

Overall, they found no evidence to suggest that obese or overweight patients received “recommended care” less frequently than normal-weight patients. In fact, obese patients received recommended care for lipid screening (72% versus 65%) and glycated hemoglobin testing (74% versus 62%) more frequently than normal-weight diabetic patients.

“Even though physicians might harbor negative attitudes towards obese patients, it doesn’t seem to be borne out in the quality of care they’re delivering,” Chang told MedPage Today. “So I think both physicians and patients can feel some degree of relief on that front.”

Diabetic patients treated by physicians who received pay-for-performance incentives received better care and had better clinical outcomes than those whose physicians were not involved in the program, according to researchers at IMS Health.

To reach these conclusions, Judy Chen and colleagues looked at the records of diabetic patients who received care from the Hawaii Medical Services Association, a large PPO between 1999 and 2006. HMSA had 19,600 diabetic at study onset and about 32,000 by 2006.

HMSA offered its physicians the opportunity to earn bonuses ranging between 1.5% and 7.5% of their base fees if they met quality-of-care targets including the use of HbA1c and LDL cholesterol testing for their diabetic patients. Beginning in 2001, participating physicians could earn nearly $6,000 in bonuses if their adherence to specified care requirements improved versus the previous year.

The provider organization defined high-quality care as receiving at least 2 tests for HbA1c and one test for LDL cholesterol in a given year.

Chen’s group found that physicians who were enrolled in the P4P program delivered high quality care 16% more frequently than physicians who were not so enrolled. The patients of physicians who participated in P4P for at least 3 consecutive years were also found to be 25% less likely to be hospitalized.

“This study showed a robust, consistent, significant, and positive association between increased receipt of appropriate laboratory monitoring of A1c and LDL cholesterol levels and decreased hospitalization rates,” Chen’s group wrote.

The proportion of diabetic patients seen by physicians enrolled in the P4P plan jumped from 79% in 1999 to 95% in 2006.

Patient risk factors like advanced age increase the likelihood of some so-called “never events” in hospitals, according to a report in last month’s Archives of Surgery. The findings do not support Medicare’s current policy of denying payments associated with treatments for such events.

To reach this conclusion, Donald Fry and colleagues analyzed 890,000 surgeries in 1,368 hospitals using the Healthcare Cost and Utilization Project’s Nationwide Inpatient Sample. They studied abdominal hysterectomy, aorto-femoral bypass, colon resection, coronary artery bypass grafting and total hip replacement.

The researchers looked for associations between patient factors like comorbidities, age and gender and 8 “never event” complications, including C. difficile, MRSA, and surgical site infections, catheter-associated vascular and urinary tract infections, mediastinitis after CABG, decubitus ulcers and post-operative pneumonia.

They found that patient age and comorbid conditions like renal failure and weight loss were associated with a much higher risk of many of these “never event” complications.

The odds ratios ranged from 1.8 for unscheduled admission as a predictor for C. difficile enterocolitis to 16.4 for malnutrition and weight loss as a risk factor for intravascular device infection.

“Calling these complications never events and refusing to pay for their treatment may advantage high-quality caregivers, but it also will penalize providers that care for the most vulnerable patients or that perform procedures with higher-than-average risk,” Fry’s group wrote.

Medicare’s “never events” list was implemented 2 years ago. It includes obvious mistakes like transfusing the wrong blood type and wrong-site surgeries.

But the list also features complications that may not be preventable. In addition to those mentioned above, the list includes falls in the hospital, inadequate blood glucose control, pulmonary embolism and drug-induced delerium.

The Massachusetts anesthesiologist accused of cooking up data for use in trials of pain medications has agreed to plead guilty to criminal charges in a deal with federal prosecutors.

Scott Reuben, who had been among the nation’s most respected investigators on the subject, had been charged with one count of healthcare fraud.

Reuben’s trouble began last year, when an internal audit conducted by Baystate Medical Center in Springfield, Mass., revealed he fabricated data for 21 studies he had conducted during the last 15 years.

The criminal charge had focused on one of these, a trial of Celebrex as part of a “multimodal” pain regimen for knee surgery. The study showed the drug was effective and was published in 2007 in Anesthesia & Analgesia.

“In fact,” the prosecution wrote in a court filing, “Reuben had not enrolled any patients into that study, and the results reported…to Anesthesia & Analgesia were wholly made up by Reuben .”

Had he not copped a plea, Reuben could have spent 10 years behind bars and been fined $250,000. The plea convinced prosecutors to recommend lighter penalties.

After Baystate spilled the beans, journals that had published his tainted articles retracted them.

Baystate terminated its contract with Reuben last spring. At the same time, he reportedly agreed to suspend his practice and was stripped of a professorship at Tufts.

Several widely accepted medical beliefs need to be re-examined in light of the scandal. Topping the list are the effect of COX-2 inhibitors on bone healing and the role of multimodal analgesic regimens in managing chronic pain.

With respect to the former, Reuben’s studies suggested the drugs had no effect on bone fusion, a finding that was contrary to the results of several animal studies.

In the 15 years since cell phones first appeared on the scene, they have spread with astonishing speed and revolutionized communications on a global scale. But right around the time the Motorola Flip-phone was the rage, reports surfaced that cell phone use might be associated with brain cancer.

Since then, the majority of research on the subject has refuted this claim, as has the most recent publication on the matter by Isabelle Deltour of the Danish Cancer Society in Copenhagen, and her colleagues.

Deltour’s group looked at registry data from 4 Scandinavian countries between 1974 an 2003, a period encompassing the birth and growth of the technology.

They found that the incidence of the 2 major forms of brain cancer either remained stable, decreased, or continued the same slow rise that had been observed in the pre-cell phone era.

These findings are “consistent with mobile phone use having no observable effect on brain tumor incidence in this period,” they wrote in the Dec. 16 issue of the Journal of the National Cancer Institute.

The registry contained 59,984 glioma and meningioma cases had been diagnosed in people between the ages of 20 and 79 during the study period.

The incidence of glioma increased in men by 0.5% annually and in women by 0.2% annually during the study.

The incidence of meningioma increased 0.8% per year in men, on average.  In women, the incidence of meningioma rose by 2.9% per year from 1974 to 1987 (when cell phones began hitting the market), then dropped by 2.1% per year between 1987 and 1991, and then began rising again at a rate of 3.8%.

Most of that recent increase in meningioma incidence occurred in women who were at least 60 years old when they were diagnosed–an age group not likely to have been heavy cell-phone users back then.

The scientists could not exclude the possibility that very heavy cell-phone use could pose risks, or that a positive association may be present for very rare brain tumors.

A meta-analysis performed by Italian scientists has shown that reducing salt intake by half in Westernized countries can reduce strokes by 23%, which amounts to about 1.25 million deaths, and reduce cardiovascular disease by 17% which amounts to nearly 3 million additional deaths per year.

Americans consume about 10 grams (or 2 teaspoons) of salt per day.

The  World Health Organization recommends that dietary salt intake should be half that. The US Department of Agriculture recommends just under 6 grams per day.

To reach their astounding conclusions, Pasquale Strazzullo and colleagues at the University of Naples pooled data from 13 prospective studies published between 1966 and 2008. The analysis covered 177,000 subjects who sustained more than 11,000 strokes or cardiovascular events.

The extra power of the meta-analysis proved decisive in reaching the positive conclusions, since only 9 showed a direct positive link between sodium intake and the adverse events (of which only 4 reached statistical significance). Three  actually showed a non-significant inverse relationship.

Studies featuring longer periods of follow-up appeared to strengthen the relationship between salt intake and stroke, although this was not the case for cardiovascular events.

The findings were not impacted by age, sex, and hypertension status.

In an accompanying editorial, Lawrence Appel of Johns Hopkins hailed the study as a “useful and welcome addition” to the confusing literature on the subject.

“At a minimum, Strazzullo and colleagues’ analyses should dispel any residual belief that salt reduction might be harmful (a canard resulting from misinterpretation of studies, often with flawed analyses),” Appel wrote.

Appel probably had in mind long-standing efforts by the food industry to oppose tougher public health policies on dietary salt intake, which have been largely successful because the above-mentioned studies had muddied the waters so completely.

The Food and Drug Administration has sent a letter to 30 companies warning that it hasn’t approved beverages containing both caffeine and alcohol, and that it intends to begin removing such products from store shelves in 30 days if the companies can’t explain why such products are safe and legal.

The letter cited research showing that the combo drinks increase the risk of motor vehicle accidents and sexual assaults.

In one such study, Mary Claire O’Brien of Wake Forest University found that nearly one quarter of all college students claimed to have consumed such beverages in the last month alone.

O’Brien found that students who consumed alcohol-laced energy drinks were 70% more likely to be taken advantage of sexually (6.4% vs. 3.7%) and more than twice as likely (3.7% vs. 1.7%) to have taken sexual advantage of someone than students who drank alcohol alone.

O’Brien reported similarly appalling statistics for riding with a driver that had been drinking (38.9% vs. 22.5%), being hurt or injured (12.3% vs. 5.9%), and requiring medical treatment (2.6% vs. 1.2%). 
 
Last year, state authorities persuaded Anheuser-Busch and MillerCoors to remove their combo drinks, known as Bud Extra, Tilt, and Sparks from the market.

But at least 30 smaller companies still market the drinks, which contain roughly the same dose of caffeine as a large cup of Joe and nearly 10% alcohol. The provocatively-named beverages include Max Vibe, Moon Shot and Slingshot Party Gel.

In its press release on the matter, the FDA cited regulations that deem as unsafe all substances added to food or alcoholic beverages unless their “particular use has been approved by the FDA, or (they are) ‘Generally Recognized As Safe.’”

In a press conference explaining the FDA’s move, Joshua Sharfstein, the agency’s principal deputy commissioner explained that the “FDA is not aware of the basis on which these manufacturers have concluded that caffeine added to alcoholic beverages is, quote, ‘Generally Recognized As Safe.’” (more…)

Physicians have quipped for years that HMG CoA Reductase inhibitors—the cholesterol-busters better known as “statins,” ought to be put in the nation’s drinking water.

After all, they have an excellent safety profile, profoundly beneficial effects on serum cholesterol and cardiovascular mortality, and may even work against sepsis and prostate cancer.

The quip is likely to be heard even more nowadays, because a study by Meredith VanderMeer and colleagues from the Oregon Department of Public Health has shown that patients who were hospitalized for seasonal (not H1N1) flu–and who by coincidence were taking statins–had a lower risk of dying from the infection.

VanderMeer reported her team’s findings at the annual meeting of the Infectious Diseases Society of America.

In their study of 2,800 people hospitalized for flu complications, 801 patients were taking statins for high cholesterol at the time of admission. Only 17 of of them died in the hospital or within 30 days of discharge. In the remaining 1999 patients who were not taking statins, 64 died.

The difference in mortality, 2.1% vs. 3.2%, amounted to a statistically significant 54% reduction, and persisted after controlling for confounding factors such as age and the use of antiviral drugs.

Patients in the study were taking a variety of statins, including Crestor, Lescol, Lipitor, Mevacor, Pravachol, and Zocor. It was not clear whether any one of them was associated with more beneficial effects than the others.

The data for the study was pulled from the CDC’s Emerging Infections Program and covered the 2007-2008 influenza season (again, not H1N1).

According to VanderMeer, the link between statins and decreased seasonal flu mortality is not entirely surprising. Flu complications like pneumonia are caused by inflammation, and statins have anti-inflammatory effects.

VanderMeer suggested that a randomized controlled trial might help confirm her teams’ findings.

In July, 2005, the prestigious Journal of the American Medical Association began requiring that all write-ups of research that had been funded by private sector sources must undergo separate statistical reviews before being accepted for publication.

Oddly, no other first-tier journal followed suit.

Benjamin Djulbegovic of the University of South Florida decided to see whether the unilateral move impacted the types of trials published in top medical peer-reviewed journals. Lo and behold, it did!

In a presentation at last month’s Peer Review Congress, Djulbegovic showed a significant drop the number of industry-funded trials published in JAMA and a coincident increase in such trials that were published in the New England Journal of Medicine and Lancet, the 2 other top-tier journals he studied.

Following Djulbegovic’s presentation, JAMA editor Catherine DeAngelis told an audience of fellow journal editors, “the cynic in me says that if you’re not submitting to JAMA because you have something to hide, so be it. God bless the rest of you for taking those [studies]!”

Djulbegovic reached his conclusion by examining all issues from the 3 journals for the 3 years before, and the 3 years after JAMA enacted its policy.

He found that compared with the preceding period, JAMA published 26% fewer commercially-funded studies after the policy was enacted (63% vs. 37%).

Meanwhile NEJM and Lancet published 12% and 10% more such trials after the JAMA policy went into effect.

The publishing rate for non-commercially funded studies was unchanged in all 3 journals.

Djulbegovic added that if industry-funded trials are simply rerouted from JAMA to another top-tier journal, then the JAMA policy wouldn’t have much impact.

That could only happen if other top-tier journals adopted similar policies.

Just days after a CDC report showed that schools across the nation had drastically reduced on-site sales of calorie-leaden snacks, a new study has revealed that kids have responded by trotting over to nearby convenience stores where they load up on goodies to their hearts’ content.

According to Temple University’s Kelley Borradaile and colleagues, Philadelphia school children spend an average of $1.07 per day on snacks at such corner stores and get 357 calories for their money.

To reach these conclusions, Borradaile’s group surveyed 833 students from 10 urban elementary and middle schools during 2008.

Most of the students were black (54%) or Hispanic/Latino (23%).

More than half (53%) the students in the study reported visiting the convenience store every day. An additional 22% reported doing so 2-4 times per week.

“For the most frequent shoppers, those who shopped both before and after school, five times per week, this would amount to about 712 calories per day, or 3,560 calories per week,” the researchers told MedPageToday.

About 30% of the purchased calories were derived from fat, 66% from carbohydrates and 23% from protein.

Chips were purchased most frequently, accounting for nearly 40% of all purchases. Candy came in second.

According to Borradaile, simply switching from fried to baked chips could reduce the kids’ caloric intake by 14%, and drinking water rather than sugar-laced drinks could cut about 60 calories per store visit.

Alas, the war on childhood obesity is being fought in many theaters. Winning the war requires a concerted effort both inside the schools and out.
