The New York Times profiles research by Harvey A. Liu and Kenneth J. Balkus Jr. of the University of Texas at Dallas to create a therapeutic nitric oxide releasing bandage. Nitric oxide can play a significant role in peripheral vasodilation, relaxation of pulmonary vasculature, and other physiological processes, such as penile erection. Therefore, an effective method of delivering this free radical should allow the development of new types of vascular stockings, bandages, and other therapeutic (or recreational) devices.
A snippet from NYT:
As they describe in a paper in Chemistry of Materials, the researchers use a zeolite, an aluminosilicate mineral that has a three-dimensional cage structure. Zeolites have been shown to be able to store and release nitric oxide and other chemicals. They embed the mineral in fibers of a biocompatible polymer, polylactic acid, as they are spun and form a tissue-like mat. The fibers are then infused with nitric oxide; by controlling the porosity of the fibers, the researchers could control the release of the gas.
The researchers say the resulting material could be incorporated into socks for diabetics that would deliver nitric oxide through the skin. It might also prove useful before transplants as a wrapping for organs to help preserve them outside the body for longer.

With the passage of healthcare reform, an estimated thirty two million new patients will try to find primary care doctors. That’s not going to be so easy because we already face a shortage of primary care doctors and about 13,000 more will be needed to take care of those newly eligible for insurance.
According to the American Medical Association, there are about 312,000 primary care doctors practicing in the United States. That includes family medicine, general practice (GP), internal medicine, and pediatrics. (In addition, there are 43,000 ob-gyn’s who also may serve as primary care doctors.) The estimate that another 13,000 will be needed comes from a study done by the Robert Graham Center for Policy Studies in Family Medicine and Primary Care in partnership with the Agency for Healthcare Research and Quality.
Sixty five million Americans already live in areas that don’t have enough primary care doctors. And relief is not on the way anytime soon. It takes 5 to 8 years for a first year medical student to be trained as a primary care doctor. And the trend for budding doctors over the past decade has been away from primary care and towards more lucrative specialties. Read more »

It’s well known that the use of imaging scans, like CTs, MRIs and PET scans, have been growing at an alarming rate. But a recent study provides some stark numbers. According to a recent CDC report, “MRI, CT or PET scans were done or ordered in 14 percent of ER visits in 2007.” That’s four times as often as in 1996. Although a physician called that growth “astounding,” it’s really no surprise.
Emergency departments are becoming more crowded, and with patient satisfaction scores becoming more influential in financial incentives for physicians, sometimes just ordering a test is the path of least resistance. Factor in the spector of defensive medicine which, according to a survey from the Massachusetts Medical Society, accounts for up to 28 percent of tests ordered, it’s a wonder that more scans weren’t ordered.
Imaging scans are a clear cost driver in healthcare, contributing $12 billion to Medicare’s bill. But costs won’t resonate with patients requesting the tests or the doctors ordering them. One encouraging sign is the recent trend of publicizing the harms of scans, like radiation from CTs. I’m finding that patients are becoming increasingly aware of the risk, and making a more informed decision after I explain it to them. It’s a small step forward.

Concierge medicine isn’t just for internal medicine or primary care anymore. It seems the concept is starting to take hold in cardiology, too:
Starting April 1, patients at Pacific Heart Institute can choose one of four plans for care. In the first option, they pay no “participation fee.” In the second option, called “Select,” they pay $500 a year for priority appointments, warfarin adjustments, defibrillator and pacemaker follow-up, notification of non-urgent lab, and test results, according to Pacific Heart Institute.
In the third option, called “Premier,” they pay $1,800, for everything in “Select,” plus e-mail communication with their doctor, same-day visits during regular office hours, priority lab testing and scheduling of diagnostics, free attendance at speaker seminars on cardiovascular issues, and a dedicated phone line to reach an institute nurse.
In the fourth option, “Concierge,” they pay $7,500 for everything in “Premier,” plus direct 24-hour access to a cardiologist via pager, e-mail, text message, plus the patient’s PHI cardiologist’s personal cell phone, annual personalized cardiovascular wellness screening, night and weekend access to a PHI cardiologist for hospital or emergency services, (regardless of whether he or she is on call) same-day visits with the cardiologist, evening and weekend office appointments and personal calls from the cardiologist.

Hospital costs for treating septicemia increased by an average of almost 12% yearly from 1997 to 2007, the AHRQ said today, citing data from its Healthcare Cost and Utilization Project. Costs jumped from $4.1 billion in 1997 to $12.3 billion in 2007. Other costly conditions in the same time period:
Osteoarthritis: 9.5% annual increase ($4.8 billion to $11.8 billion)
Back problems: 9.3% annual increase ($3.5 billion to $8.5 billion)
Acute kidney failure: 15.3% annual increase ($1 billion to $4 billion)
Respiratory failure: 8.8% annual increase ($3.3 billion to $7.8 billion)
The most important driver of cost increases in the hospital was the greater intensity of services provided during a hospital stay, which grew 3.1% per year from 1997 to 2007 and accounted for 70% of the total rise in hospital costs, the AHRQ said.
