의료종사자 혈액매개감염의 역학적 특성과 관리 = Epidemiological Characteristics and Management of Bloodborne Infections in Healthcare Workers

다국어 초록 (Multilingual Abstract)

Purpose: This study aimed to provide foundational evidence for the development of effective infection prevention strategies and standardized management systems by investigating blood and body fluid exposures among healthcare workers at a tertiary hospital and analyzing the epidemiological characteristics and management status of bloodborne infections.

Methods: A retrospective analysis was conducted on 445 cases of blood and body fluid exposure reported between 2020 and 2024. Descriptive statistics, chi-square tests, and Fisher's exact tests were used for analysis.

Results: Blood and body fluid exposures occurred relatively more frequently among women, healthcare workers in their 20s, nurses, and those with less than one year of clinical experience. When adjusted per 100 employees by occupation, medical technicians showed the highest incidence rate. Exposures most commonly occurred between March and May, in hospital wards, and were primarily associated with percutaneous injuries involving the hands and needles, particularly while handling or disposing of materials after procedures. The primary source of infection was hepatitis B virus. The incidence of bloodborne pathogen exposure showed statistically significant differences according to occupation, year of exposure, place of exposure, type and site of exposure, task during exposure, and route of exposure. Among cases requiring post-exposure prophylaxis and follow-up testing, 78.7% completed the recommended management, and no cases of seroconversion were identified. In addition, management completion rates differed significantly by place of exposure and task during exposure.

Conclusion: To prevent exposure to bloodborne infections and ensure systematic management, it is necessary to strengthen infection control education that integrates both theoretical and practical training for high-risk occupations and departments, regularly review and update operational guidelines, establish electronic-based follow-up management systems, and reinforce legal and institutional frameworks.
