Impact of the resident duty hours on in-training examination score: A nationwide study in Japan.

PURPOSE: The relationship between duty hours (DH) and the performance of postgraduate residents is needed to establish appropriate DH limits. This study explores their relationship using the General Medicine In-training Examination (GM-ITE). MATERIALS AND METHODS: In this cross-sectional study, GM-ITE examinees of 2019 had participated. We analyzed data from the examination and questionnaire, including DH per week (eight categories). We examined the association between DH and GM-ITE score, using random-intercept linear models with and without adjustments. RESULTS: Five thousand five hundred and ninety-three participants (50.7% PGY-1, 31.6% female, 10.0% university hospitals) were included. Mean GM-ITE scores were lower among residents in Category 2 (45-50 h; mean score difference, -1.05; p < 0.001) and Category 4 (55-60 h; -0.63; p = 0.008) compared with residents in Category 5 (60-65 h; Reference). PGY-2 residents in Categories 2-4 had lower GM-ITE scores compared to those in Category 5. University residents in Category 1 and Category 5 showed a large mean difference (-3.43; p = 0.01). CONCLUSIONS: DH <60-65 h per week was independently associated with lower resident performance, but more DH did not improve performance. DH of 60-65 h per week may be the optimal balance for a resident's education and well-being.

Validation of the General Medicine in-Training Examination Using the Professional and Linguistic Assessments Board Examination Among Postgraduate Residents in Japan.

PURPOSE: In Japan, the General Medicine In-training Examination (GM-ITE) was developed by a non-profit organization in 2012. The GM-ITE aimed to assess the general clinical knowledge among residents and to improve the training programs; however, it has not been sufficiently validated and is not used for high-stake decision-making. This study examined the association between GM-ITE and another test measure, the Professional and Linguistic Assessments Board (PLAB) 1 examination. METHODS: Ninety-seven residents who completed the GM-ITE in fiscal year 2019 were recruited and took the PLAB 1 examination in Japanese. The association between two tests was assessed using the Pearson product-moment statistics. The discrimination indexes were also assessed for each question. RESULTS: A total of 91 residents at 17 teaching hospitals were finally included in the analysis, of whom 69 (75.8%) were women and 59 (64.8%) were postgraduate second year residents. All the participants were affiliated with community hospitals. Positive correlations were demonstrated between the GM-ITE and the PLAB scores (r = 0.58, p < 0.001). The correlations between the PLAB score and the scores in GM-ITE categories were as follows: symptomatology/clinical reasoning (r = 0.54, p < 0.001), physical examination/procedure (r = 0.38, p < 0.001), medical interview/professionalism (r = 0.25, p < 0.001), and disease knowledge (r = 0.36, p < 0.001). The mean discrimination index of each question of the GM-ITE (mean ± SD; 0.23 ± 0.15) was higher than that of the PLAB (0.16 ± 0.16; p = 0.004). CONCLUSION: This study demonstrates incremental validity evidence of the GM-ITE to assess the clinical knowledge acquisition. The results indicate that GM-ITE can be widely used to improve resident education in Japan.

Difference in the general medicine in-training examination score between community-based hospitals and university hospitals: a cross-sectional study based on 15,188 Japanese resident physicians.

BACKGROUND: The general medicine in-training examination (GM-ITE) is designed to objectively evaluate the postgraduate clinical competencies (PGY) 1 and 2 residents in Japan. Although the total GM-ITE scores tended to be lower in PGY-1 and PGY-2 residents in university hospitals than those in community-based hospitals, the most divergent areas of essential clinical competencies have not yet been revealed. METHODS: We conducted a nationwide, multicenter, cross-sectional study in Japan, using the GM-ITE to compare university and community-based hospitals in the four areas of basic clinical knowledge". Specifically, "medical interview and professionalism," "symptomatology and clinical reasoning," "physical examination and clinical procedures," and "disease knowledge" were assessed. RESULTS: We found no significant difference in "medical interview and professionalism" scores between the community-based and university hospital residents. However, significant differences were found in the remaining three areas. A 1.28-point difference (95% confidence interval: 0.96-1.59) in "physical examination and clinical procedures" in PGY-1 residents was found; this area alone accounts for approximately half of the difference in total score. CONCLUSIONS: The standardization of junior residency programs and the general clinical education programs in Japan should be promoted and will improve the overall training that our residents receive. This is especially needed in categories where university hospitals have low scores, such as "physical examination and clinical procedures."

Impact of general medicine rotation training on the in-training examination scores of 11, 244 Japanese resident physicians: a Nationwide multi-center cross-sectional study.

BACKGROUND: Although general medicine (GM) faculty in Japanese medical schools have an important role in educating medical students, the importance of residents' rotation training in GM in postgraduate education has not been sufficiently recognized in Japan. To evaluate the relationship between the rotation of resident physicians in the GM department and their In-Training Examination score. METHODS: This study is a nationwide multi-center cross-sectional study in Japan. Participants of this study are Japanese junior resident physicians [postgraduate year (PGY)-1 and PGY-2] who took the General Medicine In-Training Examination (GM-ITE) in fiscal years 2016 to 2018 at least once (n = 11,244). The numbers of participating hospitals in the GM-ITE were 381, 459, and 503 in 2016, 2017, and 2018.The GM-ITE score consisted of four categories (medical interview/professionalism, symptomatology/clinical reasoning, physical examination/procedure, and disease knowledge). We evaluated relationship between educational environment (including hospital information) and the GM-ITE score. RESULTS: A total of 4464 (39.7%) residents experienced GM department rotation training. Residents who rotated had higher total scores than residents who did not rotate (38.1 ± 12.1, 36.8 ± 11.7, and 36.5 ± 11.5 for residents who experienced GM rotation training, those who did not experience this training in hospitals with a GM department, and those who did not experience GM rotation training in hospitals without a GM department, p = 0.0038). The association between GM rotation and competency remained after multivariable adjustment in the multilevel model: the score difference between GM rotation training residents and non-GM rotation residents in hospitals without a GM department was estimated as 1.18 (standard error, 0.30, p = 0.0001), which was approximately half of the standard deviation of random effects due to hospital variation (estimated as 2.00). CONCLUSIONS: GM rotation training improved the GM-ITE score of residents and should be considered mandatory for junior residents in Japan.

The Impact of the Hospital Volume on the Performance of Residents on the General Medicine In-Training Examination: A Multicenter Study in Japan.

Objective Although several studies have been conducted worldwide on factors that might improve residents' knowledge, the relationship between the hospital volume and the internal medicine residents' knowledge has not been fully understood. We conducted a cross-sectional study to compare the relationships of the hospital volume and hospital resources with the residents' knowledge assessed by the In-training Examination. Methods We conducted a retrospective survey and a clinical knowledge evaluation of postgraduate year 1 and 2 (PGY-1 and -2) resident physicians in Japan by using the General Medicine In-training Examination (GM-ITE) in 2014. We compared the ITE score and the hospital volume. Results A total of 2,015 participants (70.6% men; age, 27.3±2.9 years old) from 208 hospitals were retrospectively analyzed. Generalized estimating equations were used, and the results revealed that an increasing number of hospitalizations, decreasing staff number, decreasing age and PGY-2 were significantly associated with higher GM-ITE scores. Conclusion The hospital volume, such as the number of hospitalizations, is thus considered to have a positive impact on the GM-ITE scores.

Impact of inpatient caseload, emergency department duties, and online learning resource on General Medicine In-Training Examination scores in Japan.

BACKGROUND: Both clinical workload and access to learning resource are important components of educational environment and may have effects on clinical knowledge of residents. METHODS: We conducted a survey with a clinical knowledge evaluation involving postgraduate year (PGY)-1 and -2 resident physicians at teaching hospitals offering 2-year postgraduate training programs required for residents in Japan, using the General Medicine In-Training Examination (GM-ITE). An individual-level analysis was conducted to examine the impact of the number of assigned patients and emergency department (ED) duty on the residents' GM-ITE scores by fitting a multivariable generalized estimating equations. In hospital-level analysis, we evaluated the relationship between for the number of UpToDate reviews for each hospital and for the hospitals' mean GM-ITE score. RESULTS: A total of 431 PGY-1 and 618 PGY-2 residents participated. Residents with four or five times per month of the ED duties exhibited the highest mean scores compared to those with greater or fewer ED duties. Those with largest number of inpatients in charge exhibited the highest mean scores compared to the residents with fewer inpatients in charge. Hospitals with the greater UpToDate topic viewing showed significantly greater mean score. CONCLUSION: Appropriate ED workload and inpatient caseload, as well as use of evidence-based electronic resources, were associated with greater clinical knowledge of residents.

Hypothermia in victims of the great East Japan earthquake: a survey in Miyagi prefecture.

OBJECTIVE: A survey was conducted to describe the characteristics of patients treated for hypothermia after the Great East Japan Earthquake. METHODS: Written questionnaires were distributed to 72 emergency medical hospitals in Miyagi Prefecture. Data were requested regarding inpatients with a temperature less than 36ºC admitted within 72 hours after the earthquake. The availability of functional heating systems and the time required to restore heating after the earthquake were also documented. RESULTS: A total of 91 inpatients from 13 hospitals were identified. Tsunami victims comprised 73% of the patients with hypothermia. Within 24 hours of the earthquake, 66 patients were admitted. Most patients with a temperature of 32ºC or higher were treated with passive external rewarming with blankets. Discharge without sequelae was reported for 83.3% of patients admitted within 24 hours of the earthquake and 44.0% of those admitted from 24 to 72 hours after the earthquake. Heating systems were restored within 3 days of the earthquake at 43% of the hospitals. CONCLUSIONS: Hypothermia in patients hospitalized within 72 hours of the earthquake was primarily due to cold-water exposure during the tsunami. Many patients were successfully treated in spite of the post-earthquake disruption of regional social infrastructure.

Resources for business continuity in disaster-based hospitals in the great East Japan earthquake: survey of Miyagi Prefecture disaster base hospitals and the prefectural disaster medicine headquarters.

OBJECTIVE: To clarify advance measures for business continuity taken by disaster base hospitals involved in the Great East Japan Earthquake. METHODS: The predisaster situation regarding stockpiles was abstracted from a 2010 survey. Timing of electricity and water restoration and sufficiency of supplies to continue operations were investigated through materials from Miyagi Prefecture disaster medicine headquarters (prefectural medical headquarters) and disaster base hospitals (14 hospitals) in Miyagi Prefecture after the East Japan earthquake. RESULTS: The number of hospitals with less than 1 day of stockpiles in reserve before the disaster was 7 (50%) for electricity supplies, 8 (57.1%) for water, 6 (42.9%) for medical goods, and 6 (42.9%) for food. After the disaster, restoration of electricity and water did not occur until the second day or later at 8 of 13 (61.5%) hospitals, respectively. By the fourth postdisaster day, 14 hospitals had requested supplies from the prefectural medical headquarters: 9 (64.3%) for electricity supplies, 2 (14.3%) for water trucks, 9 (64.3%) for medical goods, and 6 (42.9%) for food. CONCLUSIONS: The lack of supplies needed to continue operations in disaster base hospitals following the disaster clearly indicated that current business continuity plans require revision.

The hospital educational environment and performance of residents in the General Medicine In-Training Examination: a multicenter study in Japan.

BACKGROUND: It is believed that the type of educational environment in teaching hospitals may affect the performance of medical knowledge base among residents, but this has not yet been proven. OBJECTIVE: We aimed to investigate the association between the hospital educational environment and the performance of the medical knowledge base among resident physicians in Japanese teaching hospitals. METHODS: To assess the knowledge base of medicine, we conducted the General Medicine InTraining Examination (GM-ITE) for second-year residents in the last month of their residency. The items of the exam were developed based on the outcomes designated by the Japanese Ministry of Health, Labor, and Welfare. The educational environment was evaluated using the Postgraduate Hospital Educational Environment Measure (PHEEM) score, which was assessed by a mailed survey 2 years prior to the exam. A mixed-effects linear regression model was employed for the analysis of variables associated with a higher score. RESULTS: Twenty-one teaching hospitals participated in the study and a total of 206 residents (67 women) participated and completed the exam. There were no residents who declined to participate in the exam. The mean GM-ITE score was 58 (standard deviation 8.4). The mixed-effects linear regression analysis showed that a higher PHEEM score was associated with a higher GM-ITE score (P = 0.02). Having a department of general medicine, and hospital location in a provincial community (versus an urban setting), were also shown to have a significant relationship with the higher score (P = 0.03, and P = 0.02, respectively). CONCLUSION: We found that the performance of the medical knowledge base of resident physicians was significantly associated with the educational environment of their hospitals. Improvement of the educational environment in teaching hospitals might be crucial for enhancing the performance of resident physicians in Japan.

Cognitive error as the most frequent contributory factor in cases of medical injury: a study on verdict's judgment among closed claims in Japan.

BACKGROUND: Cognitive errors in the course of clinical decision-making are prevalent in many cases of medical injury. We used information on verdict's judgment from closed claims files to determine the important cognitive factors associated with cases of medical injury. METHODS: Data were collected from claims closed between 2001 to 2005 at district courts in Tokyo and Osaka, Japan. In each case, we recorded all the contributory cognitive, systemic, and patient-related factors judged in the verdicts to be causally related to the medical injury. We also analyzed the association between cognitive factors and cases involving paid compensation using a multivariable logistic regression model. RESULTS: Among 274 cases (mean age 49 years old; 45% women), there were 122 (45%) deaths and 67 (24%) major injuries (incomplete recovery within a year). In 103 cases (38%), the verdicts ordered hospitals to pay compensation (median; 8,000,000 Japanese Yen). An error in judgment (199/274, 73%) and failure of vigilance (177/274, 65%) were the most prevalent causative cognitive factors, and error in judgment was also significantly associated with paid compensation (odds ratio, 1.9; 95% confidence interval [CI], 1.0-3.4). Systemic causative factors including poor teamwork (11/274, 4%) and technology failure (5/274, 2%) were less common. CONCLUSIONS: The closed claims analysis based on verdict's judgment showed that cognitive errors were common in cases of medical injury, with an error in judgment being most prevalent and closely associated with compensation payment. Reduction of this type of error is required to produce safer healthcare.

Questionnaire survey for challenging cases of medical professionalism in Japan.

BACKGROUND: Little information is available on evaluation of medical professionalism among Japanese physicians and on its education in Japanese medical schools. AIMS: To assess professionalism and its education in Japan. METHOD: We analysed the responses to challenges to professionalism for Japanese residents and physicians, using the Barry Questionnaire, and to survey the extent of education related to professionalism during medical school curricula. The survey was conducted at 14 teaching hospitals in Kyushu and Okinawa, using existing hospital conferences. RESULTS: We collected data from 175 participants (60 residents and 115 faculty physicians). The most challenging was the sexual harassment scenario, in which 51.4% provided the best or 2nd best answers, followed by the honesty scenario with 69.7% and the confidentiality scenario with 76.0%. Participants were more likely to provide the best or 2nd best responses to the scenarios involving physician impairment (87.4%), conflict of interest (81.1%), and acceptance of gifts (78.3%). Five (3%) participants reported learning experiences about professionalism during the curricula and the median hours for its course work were two hours. Only one resident reported that she was satisfied with these educational sessions. CONCLUSIONS: Many Japanese physicians were unable to provide an acceptable response to challenges to professionalism in several issues and few had received education in professionalism during school curricula. Greater teaching of professionalism is needed in medical education in Japan.
