[Burnout syndrome in health workers and relationship with personal and environmental factors]

High rates of professional burnout syndrome have been found among health service professionals. Our objective was to study the prevalence of burnout syndrome in hospital health workers and to determine its relationship with personal and environmental factors.

A total of 2290 health workers from five hospitals in the province of Girona (Spain) were invited to participate. Interviewees were given a specifically designed questionnaire, a questionnaire on organizational climate, and the Spanish version of the Maslach Burnout Inventory, which includes three scales: emotional exhaustion, depersonalization, and reduced personal accomplishment.

Responses were received from 1095 health workers (a response rate of 47.8%). A high level of emotional exhaustion was found in 41.6% of staff members, especially among doctors and nurses; a high level of depersonalization was found in 23%, mainly among doctors, and reduced personal accomplishment was found in 27.9%, mainly among technicians and doctors. Multiple logistic regression revealed that a high level of emotional exhaustion was associated with frequent consumption of tranquilizers or antidepressants, whereas optimism and job satisfaction showed an inverse association. The variables that were inversely associated with a high level of depersonalization were the number of years in the profession, optimism, evaluation of work as being useful and the perception of being valued by others. Reduced personal accomplishment was also inversely associated with optimism, satisfaction with the usefulness of one's work, and satisfaction with teamwork.

In view of the results obtained, to reduce professional burnout in hospitals, optimism and a sense of self-worth among individuals should be encouraged and the organizational environment should be improved.
