Abstract

Background: Respiratory syncytial virus (RSV), although frequently reported in pediatric populations, is also associated with significant morbidity and mortality in vulnerable adults. From an Infection Control perspective, it is therefore of particular concern in hospital and long-term care settings.

Objective: We report an RSV outbreak that occurred in the memory care unit of a Veterans Affairs-affiliated long-term care facility where the characteristics of the resident population posed unique challenges to halting transmission.

Setting: The outbreak occurred in a 30-bed unit within a 230-bed Veterans Affairs-affiliated long-term care facility in Florida.

Methods: An investigation was performed in coordination with the local Department of Health. All residents on the affected unit had dementia with resulting difficulty participating in infection prevention measures, including isolation, masking, and hand hygiene. Interventions implemented included twice weekly RSV testing, enhanced cleaning protocols, staggered mealtimes/outdoor dining, and cancellation of group activities, visitations, and new admissions. A retrospective case-control study was performed to assess for potential risk factors for acquiring RSV.

Results: Over a 21-day period in 2022, 20 out of 29 residents tested positive for RSV within the affected unit. No other units were involved. Univariate analysis did not find any statistically significant risk factors for acquiring RSV infection, although small sample size may have impacted the results.

Conclusions: A multifaceted approach was ultimately successful in preventing ongoing transmission of RSV within and beyond the unit. The infection control techniques utilized in this unique patient population could potentially be applicable to challenging outbreak situations at other facilities.

在一家长期护理机构的记忆护理病房发生呼吸道合胞体病毒爆发的处理。
背景:呼吸道合胞病毒(RSV)虽然经常在儿科人群中报道,但也与易感成人的显著发病率和死亡率相关。因此,从感染控制的角度来看,这在医院和长期护理环境中特别值得关注。目的:我们报告了一起发生在退伍军人事务部附属长期护理机构的记忆护理病房的RSV爆发,在那里,居住人口的特征对阻止传播构成了独特的挑战。环境:疫情发生在佛罗里达州一家拥有230张床位的退伍军人事务部附属长期护理机构的30张病床内。方法:与当地卫生部门协调进行调查。受影响单位的所有居民都患有痴呆症,因此难以参与感染预防措施,包括隔离、口罩和手卫生。实施的干预措施包括每周两次RSV检测、加强清洁方案、错开用餐时间/户外用餐、取消团体活动、探视和新入院。进行了回顾性病例对照研究,以评估感染RSV的潜在危险因素。结果:在2022年的21天内,29名居民中有20人在受影响的单位内检测出RSV阳性。没有其他单位牵涉其中。单因素分析未发现任何统计学上显著的感染RSV的危险因素,尽管小样本量可能影响了结果。结论:多方面的方法最终成功地预防了单位内外RSV的持续传播。在这一独特患者群体中使用的感染控制技术可能适用于其他设施中具有挑战性的疫情情况。
