Diagnostic accuracy of the Single‐item Measure of Burnout (Japanese version) for identifying medical resident burnout

A Systematic Review of the Single-Item Burnout Question: Its Reliability Depends on Your Purpose

BACKGROUND

Surveillance of burnout by the gold-standard Maslach Burnout Inventory (MBI) is hindered by cost and length. The validity and benchmarking of the commonly recommended and used single-item burnout question (SIBOQ) are unknown. We sought to (1) derive an equation for predicting the gold standard MBI from the SIBOQ and (2) measure the correlation of the SIBOQ with the full MBI and its subscales.

METHODS

We sought studies in PubMed along with citations by and to included studies. We included studies that either correlated the SIBOQ and the MBI or reported the rates of burnout measured by both instruments. Two reviewers extracted data and CLARITY risk of bias. We used generalized linear mixed regression to separately quantify the predictive (benchmarking) and explanatory (hot-spotting) capabilities of the SIBOQ. We created a regression equation for converting SIBOQ scores to MBI scores. We meta-analyzed correlation coefficients (r) for the SIBOQ and MBI subscales. For all analyses, we considered an r of 0.7 as acceptable reliability for group-level comparisons.

RESULTS

We included 17 studies reporting 6788 respondents. All studies had a high risk of bias, as no study had a response rate over 75% and no study was able to examine non-responders. The correlations (r) of the SIBOQ with the overall MBI were explanatory r = 0.82 and predictive r = 0.56. Regarding MBI subscales, the correlations of the SIBOQ with emotional exhaustion were adequate with r = 0.71 (95% CI 0.67-0.74; I2 = 89%), and depersonalization was r = 0.44 (95% CI 0.34-0.52; I2 = 90%). However, in 8 of 15 comparisons, the r was less than 0.70.

DISCUSSION

The SIBOQ's usually adequate explanatory abilities allow "hot-spotting" to identify subgroups with high or low burnout within a single, homogenous survey fielding. However, the predictive ability of the SIBOQ indicates insufficient reliability in comparing local results to external benchmarks.

Association between prolonged weekly duty hours and self-study time among residents: a cross-sectional study

PURPOSE

In 2024, the Japanese government will enforce a maximum 80-hour weekly duty hours (DHs) regulation for medical residents. Although this reduction in weekly DHs could increase the self-study time (SST) of these residents, the relationship between these two variables remains unclear. The aim of the study was to investigate the relationship between the SST and DHs of residents in Japan.

METHODS

In this nationwide cross-sectional study, the subjects were candidates of the General Medicine In-Training Examination in the 2020 academic year. We administered questionnaires and categorically asked questions regarding daily SST and weekly DHs during the training period. To account for hospital variability, proportional odds regression models with generalized estimating equations were used to analyse the association between SST and DHs.

RESULTS

Of the surveyed 6117 residents, 32.0% were female, 49.1% were postgraduate year-1 residents, 83.8% were affiliated with community hospitals, and 19.9% worked for ≥80 hours/week. Multivariable analysis revealed that residents working ≥80 hours/week spent more time on self-study than those working 60-70 hours/week. Conversely, residents who worked <50 hours/week spent less time on self-study than those who worked 60-70 hours/week. The factors associated with longer SST were sex, postgraduate year, career aspiration for internal medicine, affiliation with community hospitals, academic involvement, and well-being.

CONCLUSION

Residents with long DHs had longer SSTs than residents with short DHs. Future DH restrictions may not increase but rather decrease resident SST. Effective measures to encourage self-study are required, as DH restrictions may shorten SST.

Relationship between COVID-19 care and burnout among postgraduate clinical residents in Japan: a nationwide cross-sectional study

OBJECTIVE

The relationship between the care of patients with COVID-19 and mental health among resident physicians in Japan is imperative for ensuring appropriate care of patients with COVID-19 and should be clarified. We herein assessed the relationship between the care of patients with COVID-19 and mental health among postgraduate year 1 (PGY-1) and PGY-2 resident physicians and factors associated with mental health.

DESIGN

This nationwide cross-sectional study analysed data obtained using the clinical training environment self-reported questionnaire.

SETTING

An observational study across Japan among resident physicians (PGY-1 and PGY-2) from 583 teaching hospitals.

PARTICIPANTS

Examinees who took the general medicine in-training examination of academic year 2020.

PRIMARY AND SECONDARY OUTCOME MEASURES

The Patient Health Questionnaire and Mini-Z 2.0 were used to assess mental health, and experience of caring for patients with COVID-19 was divided into three groups (none, 1-10 and ≥11). The prevalence of mental conditions in the three groups was compared using the 'modified' Poisson generalised estimating equations by adjusting for prefecture-level, hospital-level and resident-level variables.

RESULTS

Of the 5976 participants analysed, 50.9% were PGY-1. The prevalence of burnout was 21.4%. Moreover, 47.0% of all resident physicians had no experience in the care of patients with COVID-19. The well-experienced group accounted for only 7.9% of the total participants. A positive association was found between the number of caring patients with COVID-19 and burnout (prevalence ratio 1.25; 95% CI 1.02 to 1.53). Moreover, the shortage of personal protective equipment was identified as a major contributor to burnout (prevalence ratio 1.60; 95% CI 1.36 to 1.88).

CONCLUSIONS

Resident physicians who experienced more care of patients with COVID-19 had slightly greater burnout prevalence than those who did not. Approximately half of resident physicians did not participate in the care of patients with COVID-19, which posed a challenge from an educational perspective.

Association between mental health and duty hours of postgraduate residents in Japan: a nationwide cross-sectional study

The new duty hour (DH) limit for doctors in Japan will begin in 2024, setting the maximum DHs for postgraduate residents at approximately 80 h weekly. To set appropriate limits, understanding the association between DHs and psychological health is necessary. Thus, we assessed the relationship between residents' psychological health and DHs. We conducted a cross-sectional study involving examinees of the General Medicine In-training Examination 2020. Mental health outcomes were measured dichotomously using the Patient Health Questionnaire-2 for depression and Mini-Z 2.0, for burnout, stress, and satisfaction. Weekly DHs were measured in seven categories at 10-h intervals. The prevalence ratios (PRs) between the DH categories were estimated for each outcome. Of the 6045 residents who provided data on DHs and psychological outcomes, 37.3% showed signs of depression, 21.6% experienced burn out, and 39.2% were highly stressed. In contrast, 62.3% were highly satisfied with their training. Proportions of burnout were higher among residents in Category 6 (≥ 90 and < 100 h; PR 1.36; 95% CI 1.11-1.66) and Category 7 (≥ 100 h; PR 1.36; 95% CI 1.10-1.68) compared with residents in Category 3 (≥ 60 and < 70 h; reference). The results partially support the weekly 80-h DH limit in terms of resident well-being.
