Diagnostic yield of dual-phase computed tomography enterography in patients with obscure gastrointestinal bleeding and a non-diagnostic capsule endoscopy.

BACKGROUND AND AIM: In patients with obscure gastrointestinal (GI) bleeding, capsule endoscopy is widely used to determine the source of bleeding. However, there is currently no consensus on how to further evaluate patients with obscure GI bleeding with a non-diagnostic capsule endoscopy examination. This study aims to determine the diagnostic yield of dual-phase computed tomographic enterography (CTE) in patients with obscure GI bleeding and a non-diagnostic capsule endoscopy. METHODS: Patients with obscure GI bleeding who were referred for capsule endoscopy were prospectively enrolled. Obscure GI bleeding was defined as overt if there was obvious GI bleeding; otherwise it was defined as occult. Patients with a non-diagnostic capsule endoscopy and no contraindications underwent a CTE. RESULTS: Capsule endoscopy was performed in 52 patients; 26 patients (50%) had occult GI bleeding and 26 patients (50%) had overt GI bleeding. CTE was then performed in 25 of the 48 patients without a definitive source of bleeding seen on capsule endoscopy. The diagnostic yield of CTE was 0% (0/11) in patients with occult bleeding versus 50% (7/14) in patients with overt bleeding (P < 0.01). Using clinical follow up as the gold standard, for the 25 patients with a non-diagnostic capsule, CTE had a sensitivity of 33% (95% confidence interval 0.15, 0.56) and a specificity of 75% (95% confidence interval 0.22, 0.99). CONCLUSIONS: In patients with a non-diagnostic capsule endoscopy examination, CTE is useful for detecting a source of GI bleeding in patients with overt, but not occult, obscure GI bleeding.

Universal health care and reform of the health care system: views of medical students in the United States.

PURPOSE: Nearly 46 million Americans did not have health insurance in 2004. Recent studies have documented physicians' support for various remedies, including universal health care. The authors undertook this study to assess medical students' views on these topics. METHOD: In 2002, the authors surveyed a national random sample of first-year and fourth-year medical students (from the American Medical Association Masterfile) to determine their views about health care reform options, including universal health care. Response data were weighted and compared using chi-squared tests; statistical significance was set at p < or = .05. RESULTS: Of 1,363 medical students, 770 completed the questionnaire (response rate = 56.5%). In rating the importance of several health care issues, more than 80% of both first-year and fourth-year students rated the expansion of health care coverage as important. Nearly all first-year (90%) and fourth-year (88%) students agreed with the statement, "Everyone is entitled to adequate medical care regardless of ability to pay." Most students favored health care reform that would achieve universal health care, with first-year students (70%) somewhat more likely than fourth-year students (61%) to support universal health care (p = .012). Students were less likely to believe that physicians support universal health care, and more likely to believe that the public does. CONCLUSIONS: Both groups of students generally support the expansion of health coverage to the uninsured and some form of universal health care. This may be relevant both to policymakers in their considerations of health care reform and to medical educators concerned with teaching students about health policy issues.

Progress and pitfalls in underrepresented minority recruitment: perspectives from the medical schools.

PURPOSE: To assess current initiatives at U.S. medical schools to recruit underrepresented minorities (URM) and to identify perceived barriers to enrollment of URM students. METHODS: We developed a survey that was mailed to the dean of Student Affairs of all U.S. allopathic and osteopathic medical schools in 2002. Respondents were asked to list their schools' URM recruitment programs and rate the effectiveness of these programs. They were also asked to indicate barriers to URM recruitment from a list of 37 potential barriers and rate their overall success with URM recruitment. RESULTS: The study had a 59% response rate. All schools reported a wide variety of initiatives for URM recruitment with > or =50% of all schools using each of the 11 strategies. The three most commonly listed barriers to URM recruitment were MCAT scores of applicants (90%), lack of minority faculty (71%) and lack of minority role models (71%). Most schools rated their recruitment efforts highly; on a scale of 1 to 10 (10 being very successful), the average score was an 8. CONCLUSION: While schools continue to invest tremendous efforts in recruiting minority applicants, admissions criteria, lack of URM faculty and the need for external evaluation remain important barriers to achieving a diverse physician workforce.

Medical students' knowledge of the U.S. health care system and their preferences for curricular change: a national survey.

PURPOSE: To measure medical students' knowledge of central issues in the U.S. health care system and to understand their perception of the importance and quality of health policy curricula at their medical schools. METHOD: A questionnaire was developed using facts from recent national and international health reports to test students' knowledge of health policy. The instrument, containing 14 questions about health policy and four questions about school curriculum on health policy, was mailed to a national probability sample of 516 first-year and 847 fourth-year students in the United States. Chi-square and t tests were used to compare the responses of first- and fourth-year students. RESULTS: A total of 295 first-year (57%) and 475 fourth-year students (56%) responded. Nearly all respondents were aware of the adverse health consequences for the uninsured, but 40% of first- and fourth-year students underestimated the numbers of uninsured in the United States. Thirty-two percent of respondents incorrectly answered that the United States had the highest life expectancy of any nation, and 27% were not aware that the United States has the highest health cost per-person of any nation. First- and fourth-year students performed similarly on knowledge questions. Ninety-six percent of respondents felt that knowledge of health policy is important to their career, and 54% expressed dissatisfaction with the health policy curriculum in medical school. CONCLUSION: Medical students have significant gaps in knowledge concerning the U.S. health care system. Most students perceive that these deficiencies are not adequately addressed in the medical school curriculum.
