(Press-News.org) Among primary care physicians, the spending patterns in the regions in which their residency program was located were associated with expenditures for subsequent care they provided as practicing physicians, with those trained in lower-spending regions continuing to practice in a less costly manner, even when they moved to higher-spending regions, and vice versa, according to a study in the December 10 issue of JAMA, a theme issue on medical education.
Regional and system-level variations in Medicare spending and overall intensity of medical services delivered to patients represent the collective practice decisions of clinicians in these different systems. Some research suggests that the nature of residency training influences the nature of physician practice, which raises the question of whether exposure to different practice and spending patterns during residency influences physicians' practice patterns and cost of care after training, according to background information in the article.
Candice Chen, M.D., M.P.H., of George Washington University, Washington, D.C., and colleagues examined the relationship between spending patterns in the region of a physician's graduate medical education training and individual physician practice spending patterns after training. The study consisted of an analysis of 2011 Medicare claims data (Part A hospital and Part B physician) for a random, nationally representative sample of family medicine and internal medicine physicians completing residency between 1992 and 2010 with Medicare patient panels of 40 or more patients (2,851 physicians providing care to 491,948 Medicare beneficiaries). Locations of practice and residency training were matched with Dartmouth Atlas Hospital Referral Region (HRR) files. Training and practice HRRs were categorized into low-, average-, and high-spending groups, with approximately equal distribution of beneficiary numbers.
For physicians practicing in high-spending regions, those trained in high-spending regions had an average spending per Medicare beneficiary per year $1,926 higher than those trained in low-spending regions. For practice in average-spending HRRs, average spending per beneficiary was $897 higher for physicians trained in high- vs low-spending regions. For practice in low-spending HRRs, the difference across training HRR levels was not significant ($533).
Overall, there was approximately a 7 percent difference in spending between physicians trained in the highest and lowest training HRR spending groups, corresponding to an estimated $522 difference between low- and high-spending training regions.
For physicians 1 to 7 years in practice, there was a 29 percent difference in spending between those trained in low- and high-spending regions; however, after 16 to 19 years, there was no significant difference.
"These observations suggest an imprinting of care-related spending behaviors that may take place during residency. Decay of the effect over time would be consistent with a training imprint that wanes because of practice environment. These findings are notable for the initial size and continuation of the association of training with physician spending patterns for up to 15 years after training. This potential imprinting has implications for physician training and potentially for hiring, particularly because major efforts are under way to reduce health care spending," the authors write.

An analysis of the non-English-language skills of U.S. medical residency applicants finds that although they are linguistically diverse, most of their languages do not match the languages spoken by the U.S. population with limited English proficiency, according to a study in the December 10 issue of JAMA, a theme issue on medical education.
More than 25 million U.S. residents have limited English proficiency, an 80 percent increase from 1990 to 2010. Limited English proficiency (LEP) may impede participation in the Englishlanguage-dominant health care system. Little ...
There has been a doubling during the last decade in the number of U.S. medical schools that have student-run free clinics, with more than half of medical students involved with these clinics, according to a study in the December 10 issue of JAMA, a theme issue on medical education.
Sunny Smith, M.D., of the University of California, San Diego, and colleagues conducted a study to assess whether there has been growth of student-run free clinics (SRFCs) in medical schools and describe the characteristics of these clinics. The first national study of SRFCs conducted in 2005 ...
In a sample of U.S. emergency departments, compared to attending physicians alone, supervised visits (involving both resident and attending physicians) were associated with a greater likelihood of hospital admission and use of advanced imaging and with longer emergency department stays, according to a study in the December 10 issue of JAMA, a theme issue on medical education.
A common assumption is that care at academic medical centers costs more than care at nonteaching hospitals in part because of a higher frequency of testing and other resource use in teaching settings. ...
PHILADELPHIA - In the first year after the Accreditation Council for Graduate Medical Education (ACGME) reduced the number of continuous hours that residents can work, there was no change in the rate of death or readmission among hospitalized Medicare patients, according to a new study published in JAMA. The study was led by researchers at the Perelman School of Medicine at the University of Pennsylvania and The Children's Hospital of Philadelphia.
"There has been a lot of speculation about the effect of the 2011 ACGME duty hour reforms on patient outcomes, so we looked ...
ROCHESTER, Minn. -- Clinical recommendations discouraging the use of CYP2D6 gene testing to guide tamoxifen therapy in breast cancer patients are based on studies with flawed methodology and should be reconsidered, according to the results of a Mayo Clinic study published in the Journal of the National Cancer Institute.
For years, controversy has surrounded the CYP2D6 gene test for breast cancer. Women with certain inherited genetic deficiencies in the CYP2D6 gene metabolize tamoxifen less efficiently, and thus have lower levels of tamoxifen's active cancer-fighting metabolite ...
Yeast cells can sometimes reverse the protein misfolding and clumping associated with diseases such as Alzheimer's, according to new research from the University of Arizona.
The new finding contradicts the idea that once prion proteins have changed into the shape that aggregates, the change is irreversible.
"It's believed that when these aggregates arise that cells cannot get rid of them," said Tricia Serio, UA professor and head of the department of molecular and cellular biology. "We've shown that's not the case. Cells can clear themselves of these aggregates."

COLUMBUS, Ohio - Thinking you're good at math and actually being good at it are not the same thing, new research has found.
About one in five people who say they are bad at math in fact score in the top half of those taking an objective math test. But one-third of people who say they are good at math actually score in the bottom half.
"Some people mis-categorize themselves. They really don't know how good they are when faced with a traditional math test," said Ellen Peters, co-author of the study and professor of psychology at The Ohio State University.
The results ...
GAINESVILLE, Fla. --- Mathematical models predicted it, and now a University of Florida study confirms it: Immunizing school-aged children from flu can protect other segments of the population, as well.
When half of 5- to 17-year-old children in Alachua County were vaccinated through a school-based program, the entire age group's flu rates decreased by 79 percent. Strikingly, the rate of influenza-like illness among 0-4 year olds went down 89 percent, despite the fact that this group was not included in the school-based vaccinations. Among all non-school-aged residents, ...
Supplemental ultrasound screening for all U.S. women with dense breasts would substantially increase healthcare costs with little improvement in overall health, according to senior author Anna Tosteson, ScD, at Dartmouth Hitchcock's Norris Cotton Cancer Center and The Dartmouth Institute for Health Policy and Clinical Practice.
In a study released Monday in the Annals of Internal Medicine, Tosteson and colleagues, including lead author Brian Sprague, MD, provide evidence on the benefits and harms of adding ultrasound to breast cancer screening for women who have had a ...
CHAMPAIGN, Ill. -- When a large protein unfolds in transit through a cell, it slows down and can get stuck in traffic. Using a specialized microscope -- a sort of cellular traffic camera -- University of Illinois chemists now can watch the way the unfolded protein diffuses.
Studying the relationship between protein folding and transport could provide great insight into protein-misfolding diseases such as Alzheimer's and Huntington's. Chemistry professor Martin Gruebele and graduate students Minghao Guo and Hannah Gelman published their findings in the journal PLOS ONE.
