Abstract

Purpose: Annual influenza vaccination is the best strategy to prevent healthcare-associated influenza transmission. Influenza vaccination rates among healthcare workers (HCWs) vary by country, region, and year. We investigated the influenza vaccination rates for HCWs during the 2017-2018 influenza season in South Korea, where a non-mandatory vaccination campaign was conducted. Methods: We retrospectively investigated factors affecting the influenza vaccination rate among HCWs during the 2017-2018 influenza season in three tertiary hospitals in Goyang City, where the non-mandatory influenza vaccination program is conducted. Results: Consequently, 6,994 of 7,180 HCWs (97%) were included, and the overall vaccination rate was 85%. Nurses had the highest rate with 92%, followed by health technicians (88%), physicians (84%), and non-medical HCWs (79%, P<0.001). Vaccination rates differed, depending on the frequency of contact with patients in the non-medical HCWs (frequent contact vs. less-frequent contact; 90% vs. 73%, P<0.001). Conclusions: The influenza vaccination rate among HCWs during the 2017-2018 influenza season in Korea was 85%, which is among the highest rates compared with previously reported non-mandatory vaccination rates in other countries. The vaccination rate may vary depending on the HCW's occupational characteristics, including the extent of contact with the patient. Therefore, a multifaceted strategy is needed to increase the vaccination rate of HCWs.

목적: 인플루엔자 예방접종은 인플루엔자 감염을 예방하고 병원 내 전파를 차단할 수 있는 가장 효과적인 방법이다. 본 연구자들은 국내 병원내 직원들의 인플루엔자 예방 접종률의 현황 및 접종률과 연관된 인자들을 살펴보고자 하였다. 방법: 2017-2018 인플루엔자 시즌 전, 경기도 고양시 내 3개 종합 병원의 인플루엔자 예방접종 캠페인 대상인 병원 직원들이 연구에 포함되었다. 연구대상자의 인구학적인 특성 및 직업적 특성을 후향적으로 수집하였다. 결과: 총 7,180명의 병원내 직원 중 6,994명(97%)이 연구에 포함되었으며 전체 예방 접종률은 85%였다. 의료직종 중에서는 간호직군이 92%로 가장 높았고, 의료기술직군(88%), 의사직군(84%), 비의료직군(79%) 순이었다(P<0.001). 비의료직군에서의 접종률은 환자와의 접촉 정도에 비해 서로 상이하였으며, 환자와 접촉이 빈번한 비의료직군의 접종률은 90%로 덜 빈번한 비의료직군의 73%보다 유의하게 높았다(P<0.001). 결론: 2017-2018 인플루엔자 시즌 병원내 직원의 예방접종률은 85%이었다. 이는 기존의 병원내 직원 대상으로 자발적인 예방접종을 진행하는 여러 국가들의 보고들과 비교했을 때 높은 편에 속한다. 병원내 직원의 특성에 따라 예방 접종률은 서로 상이하며, 병원내 직원의 예방접종률을 보다 높이기 위해서는 이러한 요인들을 포함한 다각적인 접근을 고려해야 한다.
