[Prevalence and underdiagnosis of burn out syndrome in critical services in the context of the COVID-19 pandemic].

Introduction: The importance of knowing the impact of work on people's health has increased after the COVID-19 pandemic. Burn Out (BO) syndrome arises from the tension emerging from the conflictive interaction between the worker and his or her employment. The objective was to describe the prevalence and frequency of diagnosis of BO in the health human resources of critical services of the Bahía Blanca Municipal Hospital in the context of the COVID-19 pandemic.Methods: Descriptive, cross-sectional study. The study population was the medical and nursing staff of the Intensive Care (IT), Emergency Medicine (SMU) and Clinic services who worked with COVID-19 during 2021. The Maslach Burnout Inventory (MBI) questionnaire was used and complementary closed questions to identify, among these cases, those that were diagnosed and treated by the institution.Results: Of the 219 workers, 55.3% (121/219) were nurses. In the SMU, 25% (24/96) of respondents had BO, followed by 20.4% (11/54) in Clinic and 8.7% (6/69) in IT (p value=0.004). Only 5.5% (12/219) of the total were diagnosed with BO by the institution and of this group, two people (0.9%) had previously consulted for characteristic symptoms.Discussion: A high prevalence of BO and a marked underdiagnosis were evident at the institutional level during the pandemic. Although the IT Service had the highest demand for attention, it was the one that presented the lowest BO values in relation to other services.
