[Influence of personal, professional and cross-national factors in burnout syndrome in Hispanic Americans and Spanish health workers (2007)].

BACKGROUND Burnout syndrome is related to cultural and individual factors. The aim of this study was to compare the frequency of burnout and the scores for its three components with the perceptions and the demographic and professional characteristics of the workers. METHODS Burnout syndrome was studied in 11,530 Hispanic Americans and Spanish healthcare professionals (51% male, mean age 41.7 years). The Maslach Burnout Inventory and a previously drawn up questionnaire were administered online from the Intramed website from December 2006 to September 2007. Associations were tested using multiple logistic regression. RESULTS The frequency of burnout in professionals resident in Spain was 14.9%, in Argentina 14.4%, and in Uruguay 7.9% whereas professionals in Mexico, Ecuador, Peru, Columbia, Uruguay, Guatemala and El Salvador presented frequencies of burnout of between 2.5% and 5.9%. By professions, doctors had a prevalence of burnout of 12.1%, nurses 7.2%, and dentists, psychologists and nutritionists of <6%. Amongst doctors, burnout predominated amongst doctors working in emergency departments (17%) and internal medicine departments (15.5%) whereas anaesthetists and dermatologists had the lowest prevalence (5% and 5.3%, respectively). Older age (OR=0.96), having children (OR=0.93), the perception of feeling valued (OR=0.53), optimism (OR=0.80), job satisfaction (OR=0.80), and satisfaction with salary (OR=0.91) are variables which protect against burnout. CONCLUSIONS The expression of burnout varies among nations and professions. Age (older age), having children, the perception of feeling valued, optimism, job satisfaction and satisfaction with salary are protective variables of burnout.
