Job burnout is associated with slow improvement of quality of life in the employees after a first episode of acute coronary syndrome: A hospital-based longitudinal study in China.

OBJECTIVE

This study investigated the association between job burnout and quality of life (QoL) after acute coronary syndrome (ACS) in a Chinese sample.

METHODS

This was a one-year longitudinal study. Participants included patients with a first episode of ACS who were still employed. The Copenhagen Burnout Inventory (CBI) assessed job burnout before discharge, and QoL was assessed using the Medical Outcome Study 8-Items Short Form Health Survey (SF-8) and the Seattle Angina Questionnaire (SAQ) before discharge (baseline), at one month, six months and 12 months after discharge. Generalized estimating equations determined the association between job burnout and longitudinal changes of QoL.

RESULTS

All participants were assigned to either a "low job burnout" group (n = 70) or a "high job burnout" group (n = 50), based on the upper quartile of job burnout scores. Longitudinally over 1-year follow-up period, the scores of the SF-8 and SAQ among patients with a high level of burnout were lower than those in the low job burnout group. Job burnout was significantly associated with lower physical and mental health (SF-8), as well as greater physical limitation and lower treatment satisfaction (SAQ) over time.

CONCLUSION

Job burnout at baseline predicted slow improvement of QoL after ACS in a Chinese working sample.
