Simulating the effects of reducing transfer latency from the intensive care unit on intensive care unit bed utilization in a Korean Tertiary Hospital.

Background: Latency in transferring patients from intensive care units (ICUs) to general wards impedes the optimal allocation of ICU resources, underscoring the urgency of initiatives to reduce it. This study evaluates the extent of ICU transfer latency and assesses the potential benefits of minimizing it.

Methods: Transfer latency was measured as the time between the first transfer request and the actual ICU discharge at a single-center tertiary hospital in 2021.

Health insurance system and resilience to epidemics.

We theoretically analyze the resilience (efficiency) of health insurance systems and diverse factors including trace and test technology, infection and contagion rates, and social distancing/lockdown policy, in coping with contagious diseases like COVID-19. Our findings can be summarized as follows. First, public insurance is more resilient than market insurance, as the former's investment in test technology is made at the social optimum, whereas the latter's investment is less.

Development and Validity Testing of the Worksite Health Index: An Assessment Tool to Help and Improve Korean Employees' Health-Related Outcome.

Objectives: The objective of this study was to develop the Worksite Health Index (WHI) and validate its psychometric properties.

Methods: The development of the WHI questionnaire included item generation, item construction, and field testing. To assess the instrument's reliability and validity, we recruited 30 different Korean worksites.
