The promotion of clinical research in Japan requires the establishment of a formal and systematic education and training program for clinicians to ensure they become effective clinician investigators. The first of its kind in Japan, a formal 1-year masters-degree-level training program (MCR course) was started at Kyoto University School of Medicine and Public Health. The first 28 students graduated in 2008, with most returning to their original clinical institutions.
1) As follow-up, we conducted a self-administered questionnaire survey of all 28 graduates (response rate, 86%) concerning the current status of clinical research and problems encountered at their institutions.
2) Almost 40% of respondents (n=24) reported "no time" or "no research collaborators" for clinical research.
3) Twenty respondents (83%) have attempted to promote clinical research at their hospital or workplace, but only 1 has received institutional support.
4) Over half of the respondents (54%) would like to be working in both clinical research and clinical practice at their hospital in the future (10-year timescale). Forty-two percent of respondents had a concrete image of the clinical researcher's career path.
5) Although open to improvement, the MCR program presents a concrete model for the education of clinical researchers. These findings suggest that promoting the conduct of clinical research requires the implementation of a support system and adjustment of personal and physical infrastructure.

This study examined the effectiveness of a communication program in undergraduate medical education in improving communication in physicians' clinical practice. The effectiveness of the program was assessed with a mail survey using self-rated questionnaires 9 years later. Ninety participants were follwed up in late 1994; 57.8% of them replied to the questionnaire. Of the respondents, 60% replied that programs concerned with active listening and role-playing had benefits on communicating with patients and families. In addition, 40% of respondents answered that case studies aimed at teaching comprehensive medicine with the team approach was effective in improving communication with co-medical staff. These results suggest that the communication program in undergraduate medical education is effective in improving clinical communication in clinical practice when students are highly motivated.

OBJECTIVESWith greater concern for efficient resource allocation and profiling of medical care, a case-mix classification was applied for the per-diem payment system in Japan. Many questions remain, one of which is the role of comorbidity and complication (CC) in grouping logic. We examined the association of the number of CC with the length of hospital stay (LOS) and hospital mortality as well as the proportion of LOS high outliers in 19 major diagnostic categories (MDCs).

METHODSThis study was a secondary data analysis embedded in a government research project, including anonymous claims and clinical data during a 4-month period from July 2002. Every 19 MDC, LOS, hospital mortality or proportion of LOS high outliers was compared by the number of CC and presence of any procedures.

RESULTSFrom 82 special function hospitals, 241,268 patients were enrolled in this study. Among all patients, 50.5% were identified without any CCs, 32.4% with one or two, 13.4% with three or four, and 3.7% with over five CCs. The overall mean LOS was 22.15 days and hospital mortality 26.05 cases per 1,000 admissions. In any MDC, LOS and the proportion of outliers increased as the number of CC rose. The mortality rate increased prominently in the respiratory system and the hematology system.

CONCLUSIONSThis study demonstrated that the occurrence of more CC caused longer LOS and higher mortality in some major disease categories. Further study will clarify the association of the weighted CC with resource use through controlling procedures specific for MDC.

BACKGROUND: Although social interaction and social support during the "new normal" due to coronavirus disease 2019 (COVID-19) may be related to presenteeism, the effect between these factors has not been clear for Japanese workers. The aim of this study was to describe the presenteeism of Japanese workers with reference to social interaction and social support following the lifestyle changes due to COVID-19 and to assess whether social interaction and social support affected their presenteeism. METHODS: The data were obtained from internet panel surveys from October 2020. Descriptive statistics were calculated, and multiple linear regression was conducted using the data from the first, fourth and fifth surveys, which were conducted during October to November 2020, July to August 2021, and September to October 2021, respectively. To measure presenteeism, questions from "absenteeism and presenteeism questions of the World Health Organization's Heath and Work Performance Questionnaire", short version in Japanese was utilized. Multiple linear regressions were conducted to investigate the effects of social interaction and social support-related factors on presenteeism. RESULTS: A total of 3,407 participants were included in the analysis. The mean score of absolute presenteeism from the fifth survey was 58.07 (SD = 19.71). More time spent talking with family, a larger number of social supporters and a higher satisfaction level for social support were associated with a higher absolute presenteeism score. CONCLUSIONS Our results suggested that social support reduced the presenteeism of the Japanese workers during the "new normal" due to the COVID-19 pandemic. Social interaction with family also relieved presenteeism.
