Reassessing Cohort Isolation Measures in Long-Term Care Facilities During the COVID-19 Pandemic : A Case Study Analysis of the Challenges in Korea's Cohort Isolation Measures

To critically examine South Korea's cohort isolation policy, this study conducted interviews with a doctor, nurse, caregiver, and patient’s familiy member who experienced cohort isolation in long-term care facilities during the third wave of COVID-19. The analysis of their experiences, conducted through a qualitative case study approach, yielded the following findings. First, while cohort isolation was regarded as a temporary and cautious measure in other countries, in Korea, it was enforced as though it were an obligatory procedure. Second, the successful implementation of cohort isolation required substantial human and material support, which was unfortunately lacking. As a result, long-term care facilities were, in effect, sacrificed in the effort to safeguard the broader society. Third, the lack of a centralized control tower during the cohort isolation process was highlighted as a major concern. Fourth, the management following cohort isolation was also insufficient. Many suffered from physical and mental aftereffects or experienced social discrimination due to cohort isolation. Overall, Korea’s frequent use of cohort isolation during the COVID-19 pandemic was an extremely risky measure, relying on the dedication of facility workers and the sacrifices of the users.
