ObjectivesFront-line health workers (FHWs) for COVID-19 control in South Korea have implemented a labour-intensive contact tracing programme, which places them at high risk for mental health problems. However, a few studies have examined mental health conditions in this population. We employed a qualitative approach to understand the factors perceived as causes of burn-out and embitterment among temporary FHWs to provide recommendations for supporting the workforce.MethodsWe recruited 20 FHWs to participate in semistructured focus group interviews through purposive sampling. The sample size was determined on the basis of data saturation. We collected data from October to November 2020, audiorecording and transcribing the interviews. Data analysis was conducted manually, applying the principles of grounded theory.ResultsFive levels of perceived sources of occupational burn-out and embitterment emerged. FHWs showed considerable mistrust of patients and faced ethical dilemmas in accessing and disclosing personal information. Poor collaboration with community health centre workers and interested parties as well as inadequate organisational support aggravated their conditions. Lack of social recognition and employment instability also presented challenges for FHWs’ mental health.ConclusionsThe current pandemic response system imposes great moral and emotional burdens on the workforce, prompting the need for initiatives to safeguard the values and needs of those who represent the backbone of the system. This study suggests that multilevel strategies, including providing organisational support and establishing contingency plans for workforce management and resource distribution, may improve FHWs’ mental health outcomes as well as the health system for emergency preparedness.

ObjectiveThis study aimed to explore barriers to disease control perceived by frontline healthcare workers (HCWs) working in community settings during the COVID-19 pandemic in South Korea.DesignA qualitative study was conducted using semistructured focus group interviews. All interviews were conducted in Korean on Zoom between October and November 2020, audio-recorded and transcribed for reflexive thematic analysis.SettingAll participants were working in Gyeonggi-do, the most populous province in South Korea. The province had the second-highest COVID-19 infection rates at the time of the interview.ParticipantsParticipants serving as HCWs in Gyeonggi Province were eligible to participate in the study. A total of 20 HCWs comprised of public health doctors and professional epidemiologists agreed to participate in the study.ResultsFour themes were generated. Each theme described how these barriers affected a disease control process: (1) ‘uncooperative public and unprepared community health centre’ delayed the investigation of newly diagnosed COVID-19 cases; (2) ‘uncoordinated disease control system’ impeded the collection and analysis of digital data; (3) ‘the gap between responsibilities and capabilities’ hindered the classification of close and casual contacts; and (4) ‘conflicts with persons who have different interests and priorities’ hampered epidemiological decision-making.ConclusionsOur study found that frontline HCWs experienced various challenges disrupting their work performance to control COVID-19. We provide several recommendations, such as providing HCWs with systematic interview skill training, strengthening patient information security systems, providing sufficient resources, securing a regular workforce, collecting the field experiences of HCWs, implementing task-shifting, and having regular stakeholder meetings. These strategies may promote work capacity among the frontline HCWs and subsequently strengthen emergency preparedness.
