Introduction: To increase students’ understanding of what it means to be a physician and engage in the everyday practice of medicine, a humanities program was implemented into the preclinical curriculum of the medical school curriculum. The purpose of our study was to determine how medical students’ views of being a doctor evolved after participating in a required humanities course.Methods: Medical students completing a 16-clock hour humanities course from 10 courses were asked to respond to an open-ended reflection question regarding changes, if any, of their views of being a doctor. The constant comparative method was used for coding; triangulation and a variety of techniques were used to provide evidence of validity of the analysis.Results: A majority of first- and second-year medical students (rr?=?70%) replied, resulting in 100 pages of text. A meta-theme of Contextualizing the Purpose of Medicine and three subthemes: the importance of Treating Patients Rather than a Disease, Understanding Observation Skills are Important, and Recognizing that Doctors are Fallible emerged from the data.Conclusions: Results suggest that requiring humanities as part of the required preclinical curriculum can have a positive influence on medical students and act as a bridge to contextualize the purpose of medicine. 相似文献

The initial management of bladder outflow obstruction typically related to benign prostatic hyperplasia (BPH) falls to a large extent within the remit of general practice. Referral onwards to secondary care typically arises following the failure to respond to conservative measures or when complications have supervened; the most significant of which is urinary retention. In the hospital setting, anaesthesia, constipation and immobility are the common precipitants. What follows is a practical guide to the management of these situations and provides an overview of the conservative, medical, minimally invasive and surgical treatments available. 相似文献
