ObjectiveTo evaluate the prevalence of burnout among physicians treating patients with chronic pain and to assess the potential relationships between the presence of burnout and patients' clinical outcomes such as pain relief, satisfaction with pain control, and quality of life.DesignAn observational, prospective, and noncomparative study.SettingPain medicine clinics.SubjectsPhysicians from medical departments involved in the management of chronic pain. Patients aged ≥18 years who exhibited moderate chronic pain lasting at least three months.MethodsPhysicians were evaluated with the Maslach Burnout Inventory-Human Services Survey (MBI-HSS). Patients were evaluated with the Charlson Comorbidity Index, the Brief Pain Inventory-Short Form (BPI-SF), the EuroQol-5D (EQ-5D), and ad hoc instruments for evaluating satisfaction with pain control, the extent to which the treatment met patients' expectations, and subjective impressions of improvement.ResultsOf the 301 physician participants, 22 (7.3%, 95% confidence interval [CI] = 4.9 to 10.8) met the criteria of burnout. Burnout was higher among physicians from pain units, while none of the 35 primary care physicians reported burnout. The presence of burnout was positively associated with patients' pain relief (odds ratio [OR] = 1.423, 95% CI = 1.090 to 1.858) but not with satisfaction with pain control or quality of life. Of the remaining independent variables, being treated by pain unit physicians was significantly associated with worse pain relief (OR = 0.592, 95% CI = 0.507 to 0.691), lower satisfaction (β = -0.680, 95% CI = -0.834 to -0.525), and worse quality of life (β = -4.047, 95% CI = -5.509 to -2.585) compared with being treated by physicians from other specialties (e.g., traumatologists, oncologists, etc.).ConclusionsOur study shows a lack of negative or clinically relevant (as shown by the negligible to small effect sizes) impact of burnout on patient-reported outcomes (namely, pain relief, satisfaction, and quality of life) in patients with chronic pain who are treated by pain medicine physicians.
