Chronically-ill Medicare patients spent fewer days in the hospital and received more hospice care in 2007 than they did in 2003, but their intensity of care increased as well, according to a report by the Dartmouth Atlas Project.
While in the hospital less, patients had many more visits from physicians, particularly specialists, and spent more days in intensive care units, as result of growth in intensive care and specialist capacity, the researchers said.
Intensive interventions can lower a patients’ quality of life and cost more, the researchers noted. About one-fourth of all Medicare spending stems from the last year of life, and much of the growth in Medicare spending is the result of the high cost of treating chronic disease, the authors noted. Following patient preferences for end-of-life care may reduce such spending. Read more »

There was an interesting study published this week in the journal Radiology:
Rising Use of CT in Child Visits to the Emergency Department in the United States, 1995–2008 (Abstract)
The results are not surprising to anyone who has been working in medicine in the US over the last fifteen years. Basically, in 1995, a kid visiting the ER had a 1.2% likelihood of getting a CT scan, and by 2008, that number was 5.9%.
I had written about this general phenomon not too long ago, in defense of the general increase of CT utilization in the ER, largely on the basis that CT is a better tool: it provides diagnoses in a rapid and timely manner, and excludes many potential life threats, saving lives and mitigating malpractice risk. That was largely relevant to the adult population, though, and kids are not, as they say, just little adults. The increase in scanning children is more dramatic, especially given the generally lower incidence of disease in kids compared to adults and the chonrically ill. Read more »

I’ve spent some time thinking about this survey. I couldn’t find any better information on the survey than the press release from the University of the West of England (UWE). Perhaps in the future it will be published in a journal for better review.
The survey was apparently done by the new eating disorder charity The Succeed Foundation in partnership with the University of the West of England (UWE). The editor’s notes indicate 320 women (ages 18 – 65 years, average age 24.49) studying at 20 British universities completed The Succeed Foundation Body Image Survey in March 2011.
Notably, the survey found that 30% of women would trade at least one year of their life to achieve their ideal body weight and shape. Read more »

The use of Motrin, Aleve and other non-steroidal anti-inflammatory drugs (NSAIDS) is associated with erectile dysfunction, according to a study by scientists affiliated with Kaiser Permanente.
The apparent link surprised the scientists. They had hypothesized that the commonly used pain-killers would actually reduce the risk of erectile dysfunction since NSAIDS protect against heart disease, which has in turn been linked to the troubling condition.
To reach their surprising conclusion, Steven Jacobsen and colleagues used data from Kaiser’s HealthConnect EHR, an associated pharmacy database, and self-reports about NSAID use and erectile dysfunction from an ethnically diverse population of 80,966 men between the ages of 45 and 69.
After controlling for age, ethnicity, race, body mass index, diabetes, smoking status, hypertension, high cholesterol and coronary artery disease, the scientists found that men who used NSAIDS at least 3 times per day for at least 3 months were 2.4 times more likely to experience erectile dysfunction than those who did not consume them on a regular basis. The link persisted across all age categories.
Remarkable in its own right was the finding that overall, 29% of the men in the study reported some level of erectile dysfunction.
The authors emphasized that their findings do not prove that NSAID use causes erectile dysfunction. For example, the study findings could have been confounded by factors not considered by the scientists (such as subclinical disease or the severity of the comorbid conditions that were studied), and the chance that NSAID use was actually an indicator for other conditions that caused erectile dysfunction.
In addition, the scientists recognized that their study had some limitations. These included an inability to temporally link NSAID use and the development of ED, and possible selection bias.
As a result, they cautioned men against discontinuing NSAIDs based solely on the findings of their study. “There are many proven benefits of non steroidals in preventing heart disease and for other conditions. People shouldn’t stop taking them based on this observational study. However, if a man is taking this class of drugs and has ED, it’s worth a discussion with his doctor,” Jacobsen said in an interview.
The write-up appears in the Journal of Urology.

IBM and the Institute of Bioengineering and Nanotechnology in Shanghai have designed a new type of polymer that can detect and destroy antibiotic-resistant bacteria such as MRSA. The polymer nanostructures also prevent bacteria from developing drug resistance. Moreover, because of the mechanism by which the nanostructures work, they don’t affect circulating blood cells, and, unlike most traditional antimicrobial agents, the nanostructures are biodegradable, naturally eliminated from the body rather than remaining behind and accumulating in tissues.
