Fatalities caused by pneumonia and underlying diseases from COVID-19 infection show the highest relative frequency among elderly people. Long-term care facilities for elderly people have continued to be the areas most vulnerable to COVID-19. We examined the effectiveness of training for infection control and COVID-19 at elderly care facilities. After sending questionnaires to all long-term elderly care facilities in Ibaraki prefecture, Japan during January 18-29, 2022, we received useful responses from 98 facilities. Using logistic regression, we regressed a dummy variable for outbreak experience to dummy variables representing routine but partial training, routine training for all staff members, long-term care facilities for elderly people, numbers of nurses, and numbers of residents. Outbreak experiences of two types were inferred, as represented by a dummy variable for a COVID-19 outbreak at the facility, and by a dummy variable for outbreak experience at the facility before COVID-19 was found. Multivariate analysis indicated routine training for all staff members as the most effective, in fact the only effective, countermeasure against COVID-19 outbreak.
由 COVID-19 感染引起的肺炎和基础疾病导致的死亡在老年人中占比最高。老年人长期护理机构一直是最容易受到 COVID-19 影响的地区。我们调查了在老年人护理机构中进行感染控制和 COVID-19 培训的效果。我们于 2022 年 1 月 18 日至 29 日向日本茨城县所有长期老年人护理机构发送了问卷，收到了 98 家机构的有效回复。我们使用逻辑回归，将爆发经验的虚拟变量回归为代表常规但部分培训、所有员工常规培训、老年人长期护理机构、护士人数和居民人数的虚拟变量。通过一个代表该机构 COVID-19 爆发的虚拟变量和一个代表该机构在发现 COVID-19 之前爆发经验的虚拟变量，推断出两种类型的爆发经验。多变量分析表明，对所有员工进行常规培训是最有效的，实际上也是唯一有效的 COVID-19 爆发对策。
