Objective: High mortality from cancer and rising patient numbers can trigger distress among oncologists because of a heavy and emotionally demanding workload. This systematic review and meta-analysis assesses the prevalence of high levels of distress among oncologists.
Methods:The PRISMA protocol is registered at the PROSPERO international prospective register (Ref. 2015:CRD42015016325). We categorized data items according to the following distress factors: burnout, psychiatric morbidity, stress, depression, disrupted sleep, stressinduced physical symptoms, and substance use. We meta-analysed the prevalence of burnout and psychiatric morbidity using random effects models with MetaXL software.
Results:The meta-analyses showed that 32% of 4876 oncologists had high burnout (±CI 28% to 36%) and 27% of 2384 had high psychiatric morbidity (±CI 23% to 32%). Studies also showed that 42 to 69% feel stressed at work, > 12% of oncologists screen positive for depression, many oncologists suffer from sleep deprivation, up to 30% drink alcohol in a problematic way, up to 20% of junior oncologists use hypnotic drugs and some frequently experience stress-induced complaints such as ulcers, gastric problems, headaches and arrhythmia.
Conclusions:Occupational distress reduces career satisfaction, affects patient care and increases the chances of oncologists switching to another area of medicine therefore future research should explore appropriate interventions.Keywords: stress, burnout, psychiatric morbidity, sleep, meta-analysis, oncology, cancer.
