Prevalence of scabies in long-term care hospitals in South Korea

Abstract

Background Scabies is a common contagious skin disease. With the economic growth in South Korea, the incidence of scabies has decreased. However, with the recent advancements in medical facilities, mainly the establishment of long-term care hospitals (LTCHs), scabies is now con-sidered an emerging public health problem. Methodology/Principal findings To examine the prevalence and management of scabies in LTCHs in South Korea, we contacted all 1,336 LTCHs registered at the Health Insurance Review and Assessment Service in South Korea in 2018. A total of 110 LTCHs completed a questionnaire, and we analyzed their responses. In the last 5 years, 71.8% (79/110) of LTCHs had a high incidence of scabies (suspected/confirmed cases). Usually, patients aged older than 80 years (45.5%) were diagnosed with the disease, with more women being affected than men. Only 30.0% of the patients were transferred to scabies-restricted rooms, and very few LTCHs (7.0%) had special departments for scabies. Fifty-five (61.1%) of 90 LTCHs reported contact between scabies patients and nurses, nurse aides, caregivers, and other employees (hereinafter, referred to as primary exposure), with 29 (32.2%) LTCHs reporting infections due to primary exposure. The most common challenges in managing scabies were patient isolation (47.8%), diagnosis (31.1%), management of individuals exposed to an individual with scabies (17.8%), lack of staff for managing the patients (16.7%), and treatment (11.1%). Conclusions The incidence rate of scabies in LTCHs in South Korea has increased. Regular and enhanced staff training is needed, considering that most hospitals rarely focused on the handling of equipment and furniture used by scabies patients and on educating their health-care staff. These findings can be used to develop various strategies to reduce the prevalence of scabies.
