Le résumé fourni par la source

INTRODUCTION: Measles, mumps, rubella, and varicella (MMRV) represent risk to HCWs. Checking on antibodies against MMRV is an important part of infection control among nursing staff for their own health, their colleagues and for the health of patients. Screening for immunity against MMRV is an initial step before vaccination of nursing staff. This study is to describe immunity status against MMRV by screening nursing staff in a tertiary care hospital in Riyadh. METHODS: A cross sectional survey among nursing staff was conducted from July to August 2019 at Prince Sultan Military Medical City. A convenience sampling was used to screen 1534 nursing staff working at several high-risk departments. Record for their immune status and antibody titer for MMRV were reviewed using a data collection form. RESULTS: Screening for immunity among nursing staff found that; 79.3% were immune against measles; 75.5% to be immune against mumps; 95.8% were immune against rubella; and 67% were immune against varicella. The highest proportion of immune nursing staff against measles (96.3%) and varicella (93.5%) was found in Intensive care department while the highest proportion of immune staff against mumps (89.4%) was found in Long Stay department, and against rubella (97.5%) in Hemodialysis department. On the other hand, It was found that Hemodialysis Department had the Highest proportion of non-immune staff against measles (35.6%), mumps (39%), and varicella (56.3%), while Emergency Department had the lowest proportion of immune staff (6%) against rubella. CONCLUSION: Despite that immunity among nurses screened was good on some departments; however, such results need improvement in these critical areas. These finding emphasize the importance of the currently mandatory screening for MMRV before employment. We suggest conducting comprehensive programs to increase awareness and vaccination coverage in areas with low rates of immunity.
