A qualitative study on the adoption of the new duty hour regulations among medical residents and faculty in Korea.

Duty hour regulations (DHRs) were enforced in 2017 in Korea to prevent the detrimental effects of excessively prolonged working hours among medical residents. We investigated the adoption of and implications of the new DHRs among medical residents and faculty members. Semi-structured interviews were conducted with 15 medical residents and 9 faculty members across general surgery, internal medicine, obstetrics-gynecology, and pediatrics departments at Chonnam National University Hospital. Based on the constructivist grounded theory, we developed themes from the data by concurrent coding and analysis with theoretical sampling until data saturation. In addition, respondent validation was used to ensure accuracy, and all authors remained reflexive throughout the study to improve validity. The methods of DHRs adoption among residents and faculty members included the following 4 themes: DHRs improved work schedule, residents have more time to learn on their own, clinical departments have come to distribute work, organization members have strived to improve patient safety. Residents have undertaken initial steps towards creating a balance between personal life and work. Teamwork and shift within the same team are the transitions that minimize discontinuity of patient care considering patient safety. Teaching hospitals, including faculty members, should ensure that residents' work and education are balanced with appropriate clinical experience and competency-based training.

Personal Factors Affecting Therapeutic Responses to BCG Vaccination in Asthmatics.

PURPOSE: Bacille Calmette-Guérin (BCG) vaccination has been reported to be an effective treatment for asthma in several animal models. This study investigated whether the response to BCG treatment in asthma depends on subject clinical characteristics. METHODS: Stable asthma patients were vaccinated with BCG. One month later, alterations in pulmonary function after vaccination and their relationships with subject clinical characteristics were determined. RESULTS: Of 149 patients with asthma, 54 (36.2%) showed a good or fair response to BCG. The ΔFEV1 after vaccination was significantly related to age (r=-0.348, P<0.001), peripheral blood eosinophil counts (r=0.315, P<0.001) and baseline FEV1, expressed as % personal best value (r=-0.474, P<0.001), but not to FEV1 % predicted value (r=-0.066, P>0.05). A good/fair response was highly prevalent in atopic females compared with atopic males, especially among those aged ≤50 years (90.9% vs. 40.0%, P=0.024). Age (P<0.001, odds ratios (OR)=0.92, confidence interval (CI)=0.88-0.96) and atopy (P<0.01, OR=4.95, CI=1.70-14.44) were significant predictors for a good/fair response in females. However, blood eosinophil counts (P<0.05, OR=1.18, CI=1.01-1.39) and FEV1 % best (P<0.001, OR=0.86, CI=0.79-0.94), but not age or atopy, were significant predictors in males. Approximately three-quarters of the males were smokers. CONCLUSIONS: The therapeutic effect of BCG in asthma may differ according to patient clinical characteristics. The greatest benefit occurred in young atopic females. Asthma activity indices, such as eosinophilia and FEV1 % best, were more predictive of a good/fair response in males; this may have been related to cigarette smoking.
