Medical residents' knowledge of dietary supplements.

INTRODUCTION: The widespread use of complementary and alternative medicine modalities such as dietary supplements has prompted many medical schools to offer courses covering such topics. To date, little is known about the impact of these courses on medical graduates' knowledge. This study was designed to evaluate resident physicians' level of understanding of popular dietary supplement regulation and to determine whether an interactive online curriculum could aid in improving such knowledge. METHODS: A multicenter online educational intervention was developed and administered to physicians at 15 internal medicine residency programs throughout the United States, between March 1, 2006 and June 30, 2006. Pretest performance was used to measure baseline knowledge of commonly used dietary supplements. Posttest performance compared with pretest performance measured the effectiveness of the educational intervention. RESULTS: A total of 335 physicians completed the module. Baseline knowledge of dietary supplements was low (average pretest score 59.7%). More than one-third of respondents were unaware of the reasons for use of saw palmetto and black cohosh. Results for questions on safety and drug-supplement interactions were similarly low. Only 57% of physicians knew that kava kava has been associated with hepatitis. Only 15% were aware that St. John's Wort can lower cyclosporine levels. With regards to knowledge of efficacy, only 36% were aware that fish oil has been shown to lower triglyceride levels. After completion of the curriculum, scores improved significantly (P < 0.001) in all question/content areas. CONCLUSIONS: Residents' knowledge of dietary supplements is poor. An online didactic module may improve knowledge and potentially enhance patient-physician communication regarding the use of such products.

Impact of duty hour regulations on medical students' education: views of key clinical faculty.

BACKGROUND: Teaching faculty have valuable perspectives on the impact of residency duty hour regulations on medical students. OBJECTIVE: The objective of this study was to elicit faculty views on the impact of residency duty hour regulations on medical students' educational experience on inpatient medicine rotations. DESIGN AND PARTICIPANTS: We conducted a National Survey of Key Clinical Faculty (KCF) at 40 internal medicine residency programs affiliated with U.S. medical schools using a random sample stratified by National Institutes of Health funding and program size. MEASUREMENTS: This study measures KCF opinions on the effect of duty hour regulations on students' education. RESULTS: Of 154 KCF targeted, 111 responded (72%). Fifty-two percent of KCF reported worsening in the overall quality of students' education compared to just 2.7% reporting improvement (p < 0.001). In multivariate analysis adjusted for gender, academic rank, specialty, and years of teaching experience, faculty who spent >/=15 hours per week teaching were more likely to report worsening in medical students' level of responsibility on inpatient teams [odds ratio (OR) 3.1; 95% confidence interval (CI) 1.3-7.6], ability to follow patients throughout hospitalization (OR 3.2; 95% CI 1.3-7.9), ability to develop working relationships with residents (OR 2.3; 95% CI 1.0-5.2), and the overall quality of students' education (OR 3.3; 95% CI 1.4-8.1) compared to faculty who spent less time teaching. CONCLUSION: Key clincal faculty report concerns about the impact of duty hour regulations on aspects of medical students' education in internal medicine. Medical schools and residency programs should identify ways to ensure optimal educational experiences for students within duty hour requirements.

Multicenter implementation of a shared graduate medical education resource.

BACKGROUND: The Accreditation Council of Graduate Medical Education (ACGME) is changing residency program assessment to include education outcomes assessment, challenging resources of residency training programs. The internet is a means of sharing education resources among training programs. METHODS: A multicenter survey was distributed to leaders of 80 internal medicine residency training programs that shared an online medical knowledge curriculum that included education outcomes assessment. Program characteristics, curriculum implementation methods, and use of educational outcome assessment were analyzed to determine how implementation differed among programs. RESULTS: Seventy-four programs (92%) completed the survey. The programs vary in medical school affiliation, number of house staff, and proportion of students who specialize on graduation. They most commonly use the curriculum to augment a preexisting curriculum (37 programs [50%]); 41 programs (56%) use the curriculum to comply with ACGME requirements. The programs differ in how they adapt the curriculum to their needs, most commonly by discussing modules with house staff (47 programs [63%]). In 61 programs (82%), module completion is mandatory. Thirty-five programs (47%) use penalties to encourage module completion, most commonly poor evaluation scores (15 programs [20%]) or withholding of promotion (12 programs [16%]). Nearly all programs (71 [97%]) track module completion; 34 programs (47%) track group performance on learning objectives; and 8 programs (11%) alter their educational curriculum based on group performance. CONCLUSIONS: A medical knowledge curriculum that includes education outcome assessment can be adapted at a range of residency training programs, helping them to comply with ACGME requirements. However, most residency training programs are not using outcomes data to their full potential.

Effect of residency duty-hour limits: views of key clinical faculty.

BACKGROUND: To determine the effect of duty-hour limitations, it is important to consider the views of faculty who have the most contact with residents. METHOD: We conducted a national survey of key clinical faculty (KCF) at 39 internal medicine residency programs affiliated with US medical schools selected by random sample stratified by federal research funding and program size to elicit their views on the effect of duty-hour limitations on residents' patient care, education, professionalism, and well-being and on faculty workload and satisfaction. RESULTS: Of 154 KCF surveyed, 111 (72%) responded. The KCF reported worsening in residents' continuity of care (87%) and the physician-patient relationship (75%). Faculty believed that residents' education (66%) and professionalism, including accountability to patients (73%) and ability to place patient needs above self-interests (57%), worsened, yet 50% thought residents' well-being improved. The KCF reported spending more time providing inpatient services (47%). Faculty noted decreased satisfaction with teaching (56%), ability to develop relationships with residents (40%), and overall career satisfaction (31%). In multivariate analysis, KCF with 5 years of teaching experience or more were more likely to perceive a negative effect of duty hours on residents' education (odds ratio, 2.84; 95% confidence interval, 1.15-7.00). CONCLUSIONS: Key clinical faculty believe that duty-hour limitations have adversely affected important aspects of residents' patient care, education, and professionalism, as well as faculty workload and satisfaction. Residency programs should continue to look for ways to optimize experiences for residents and faculty within the confines of the duty-hour requirements.

Physicians' understanding of the regulation of dietary supplements.

BACKGROUND: After passage of the Dietary Supplement Health and Education Act, herbs and other supplements were allowed to be sold to the public without Food and Drug Administration (FDA) approval or premarket evaluation. Data suggest that many people are unaware of this lack of governmental oversight and may rely on their physicians for education in this arena. This study was designed to evaluate physicians' level of understanding of dietary supplement regulation and the adverse event reporting process and to determine whether an interactive online curriculum could aid in improving knowledge. METHODS: A multicenter online educational intervention was developed and administered to physicians at 15 internal medicine residency programs throughout the United States between March 1, 2006, and June 30, 2006. Pretest performance was used to measure baseline knowledge, while posttest performance compared with pretest performance measured the effectiveness of the educational intervention. RESULTS: A total of 335 physicians completed the module. Ninety percent of those completing the module were residents, while 10% were attending physicians. Baseline knowledge of dietary supplement regulatory issues was poor. The total average pretest score was only 59% (986/1675). The average score rose to 91% (1526/1675) after completion of the curriculum (P<.001). With regard to specific content areas, about one third of physicians were unaware that dietary supplements did not require FDA approval or submission of safety and efficacy data before being marketed. Similar percentages believed that there are regulations in place to ensure supplement quality. Most physicians were unaware that serious adverse events due to the use of supplements should be reported through the FDA MedWatch system. CONCLUSIONS: Physician knowledge of dietary supplement regulation and adverse event reporting is poor. An online didactic module may improve knowledge and potentially enhance patient-physician communication regarding the use of such products.

Physician knowledge of national cholesterol guidelines before and after an interactive curriculum.

An interactive curriculum on National Cholesterol Education Program (NCEP) III guidelines was developed and distributed online to 877 physicians at 37 internal medicine residency training programs. Baseline knowledge of NCEP guidelines was tested before the curriculum. A test after the curriculum was compared with baseline performance to determine the impact of the curriculum. Performance was compared based on year of training or attending status. Scores for baseline knowledge of NCEP III concepts were 21.8% for residents and 23.2% for attending physicians, a difference that was not statistically significant. Postgraduate-year (PGY)-3 residents performed better than PGY-1 residents (26.5% vs 17.8%, p <0.05). Scores for specific concepts were 29.2% for pharmacology, 14.2% for major cardiovascular risk factors, 32.9% for coronary heart disease risk-equivalent conditions, 15.2% for diagnosis of metabolic syndrome, and 17.3% for treatment of patients with metabolic syndrome. For hypothetical clinical cases, attending physicians performed better than residents (63.2% vs 42.5%, p <0.05) and PGY-3 residents performed better than PGY-1 residents (47.7% vs 36.5%, p <0.05). After the curriculum, knowledge increased for all concepts (22.5% before vs 61.3% after the test, p <0.05). In conclusion, resident and attending physician knowledge of NCEP III guidelines is poor and can be improved by an interactive curriculum delivered online.

Physician familiarity with diagnosis and management of hypertension according to JNC 7 guidelines.

Physician knowledge of the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) guidelines is unknown and may contribute to the prevalence of uncontrolled hypertension. Our objective was to determine physician knowledge of JNC 7 guidelines and whether online instruction could improve knowledge. A pretest served as baseline knowledge, and comparison with a post-test after completing an online didactic demonstrated improvement in knowledge. Participants included 1280 physicians at 45 internal medicine residency training programs. Average baseline knowledge of six concepts of hypertension was 51.2%. Attending physicians performed better than trainees on some but not all concepts (p<0.05). Third-year post-graduate trainees performed better than first-year trainees on some but not all concepts (p<0.05). Knowledge increased significantly on all concepts after completing the curriculum (p<0.05). The authors demonstrated that physician knowledge of JNC 7 guidelines is poor but can be improved by an online curriculum. Further study is needed to determine the impact of physician education on clinical outcomes in individuals with hypertension.

High prevalence and correlates of low bone mineral density in young adults with sickle cell disease.

Sickle cell disease (SCD) is a prevalent genetic disorder in which sickle hemoglobin leads to tissue hypoxia and adverse effects on bone. Published studies suggest that children with SCD often have undiagnosed osteopenia or osteoporosis. Minimal data exist on the prevalence of low bone mineral density (BMD) in adults. Our objective was to describe the prevalence of osteopenia and osteoporosis in adults with SCD and to identify patient or disease characteristics associated with low BMD. We conducted a cross-sectional study of adults with SCD. Through questionnaires, we collected data about disease course and osteoporosis risk factors. Patients underwent dual X-ray absorptiometry (DXA) measurement of BMD at the hip, spine, and forearm and sampling of blood and urine for markers of bone turnover, sickle cell disease severity, and secondary causes of osteoporosis. Our main outcome measure was prevalence of osteopenia and osteoporosis as defined by WHO criteria. Of 32 adults with SCD (14 men and 18 women) with a mean age of 34 years, 72% (95% confidence interval 53-86%) had low BMD at one or more anatomic sites. Thirteen patients were classified as osteoporotic and 10 as osteopenic. The prevalence of low BMD was greatest in the lumbar spine (66% of patients). Significant correlates of decreased BMD included low BMI (P < 0.01), male sex (P = 0.02), and low serum zinc concentrations (P < 0.01). The prevalence of osteopenia and osteoporosis in young adults with SCD is extremely high. Further research is needed to address fracture risk and therapeutic interventions.
