Cross-cultural comparison of the patient-centeredness of the hidden curriculum between a Saudi Arabian and 9 US medical schools

BACKGROUND: The implicit hidden curriculum strongly influences medical students\u27 perceptions of the importance of patient-centeredness. A new instrument, the Communication, Curriculum, and Culture Survey (C3), already used to assess this hard-to- access part of the curriculum in the US, has potential for use in cross-cultural comparisons. OBJECTIVE: To use the C3 to perform a pilot cross-cultural comparison of the patient-centeredness of the hidden curriculum between a Saudi medical school and 9 U.S. medical schools. DESIGN: Senior Saudi medical students completed the C3 and a second instrument, the Patient-Provider Orientation Scale (PPOS), which measured their attitudes toward patient-centered behavior. PARTICIPANTS: Senior Saudi medical students. RESULTS: 139/256 (54%) Saudis completed the C3; 122/256(48%) completed the PPOS. Means for 2 out of 3 of the C3\u27s domains (0-100 scale) were lower for the Saudis than those for the Americans (95% confidence intervals in parentheses): 47 (45, 50) vs. 55 (53, 58); 54 (50, 58) vs. 68 (67, 70); they overlapped in the third: 60 (57, 63) vs. 62 (60, 63). The mean Saudi PPOS score was 4.0 (3.9, 4.1); for the American medical schools, 4.8 (4.8-4.8) (1-6, least to most patient-centered). CONCLUSIONS: In this preliminary study the data suggest that the patient-centeredness of the hidden curriculum differs in Saudi and US medical schools in 2 out of 3 domains. Cross-cultural use of instruments such as the C3 can highlight such important differences and help educators evaluate their curriculum from an international, as well as a local perspective. Use of instruments across borders is a growing trend and an indicator of the increasing globalization of medical education

Effect of residual interatrial shunt on migraine burden after transcatheter closure of patent foramen ovale

OBJECTIVES: This study sought to evaluate the long-term effect of transcatheter patent foramen ovale (PFO) closure on migraineurs with and without aura and examine the effect of residual right-to-left shunt. BACKGROUND: Many studies reported improvement in migraine symptoms after PFO closure, yet randomized trials failed to reach its clinical endpoints. METHODS: The study retrospectively analyzed data from 474 patients who underwent transcatheter PFO closure at Massachusetts General Hospital. Patients completed a migraine burden questionnaire at baseline and at follow-up. Migraine severity is reported as migraine frequency (days/month), average duration (min), and migraine burden (days × min/month). Improvement following closure was defined as complete abolishment of symptoms or >50% reduction in migraine burden. RESULTS: A total of 110 migraineurs who underwent PFO closure were included; 77.0% had aura and 23.0% were without aura, and 91.0% had a cryptogenic stroke. During long-term median follow-up of 3.2 (interquartile range: 2.1 to 4.9) years, there was a significant improvement in migraine symptoms in migraineurs with or without aura. Migraine burden was reduced by >50% in 87.0% of patients, and symptoms were completely abolished in 48%. Presence of aura was associated with abolishment of migraine (odds ratio: 4.30; 95% confidence interval: 1.50 to 12.30; p = 0.006). At 6 months after PFO closure, residual right-to-left shunt was present in 26% of patients. Absence of right-to-left shunt was associated with improvement in migraine burden by >50% (odds ratio: 4.60; 95% confidence interval: 1.30 to 16.10; p = 0.017). CONCLUSIONS: Long-term follow-up after transcatheter PFO closure was associated with significant improvement in migraine burden. Aura was a predictor of abolishing symptoms. Absence of residual right-to-left shunt was a predictor of significant reduction in migraine burden.Accepted manuscrip
