■17个州在2021年中期为医护人员(HCWs)引入了COVID-19疫苗授权。先前对这些任务的影响的研究集中在疗养院部门,需要更多的证据来证明它们对整个HCW人群的影响。
■研究国家COVID-19疫苗对HCWs的要求与该人群疫苗摄入量之间的关系。
■这项重复的横断面研究包括每两周一次,从2021年5月26日至10月11日的家庭脉搏调查中获得的25至64岁在医疗机构工作或志愿服务的成年人的个人水平数据。分析是在2022年11月至2023年10月之间进行的。
■宣布国家COVID-19疫苗授权。
■一项指标,表明所采样的HCW是否曾经接受过COVID-19疫苗,以及HCW是否完成或打算完成主要COVID-19疫苗接种系列的指标。使用交错差异方法的事件研究分析比较了每次任务宣布之前和之后,任务和非任务状态下的HCWs的疫苗摄取。通过常规COVID-19检测代替疫苗接种(即,测试选项)并按HCWs的年龄(25-49岁或50-64岁)检查异质关联。
■研究样本包括31142名HCWs(平均[SD]年龄,45.5[10.6]岁;72.1%的女性)来自45个州,其中16项介绍了HCWs的COVID-19疫苗授权。结果表明,与任务相关的3.46个百分点(pp)(95%CI,0.29-6.63pp;P=.03)曾经接种过COVID-19疫苗的HCWs比例增加,并且在任务宣布后2周完成或打算完成主要疫苗接种系列的比例从基线比例87.98%,86.12%增加3.64-pp(95%CI,0.72-6.57pp;P=.02)分别。在分层分析中,仅在没有测试选项的授权州和25至49岁的HCWs中检测到正相关,这表明与基线比例相比,疫苗接种增加了3.32%至7.09%。
■这项重复的横断面研究发现,国家COVID-19疫苗对HCW的要求与HCW的疫苗摄取增加有关,尤其是在年轻的HCWs和那些没有测试选项的州。这些发现表明,疫苗授权有可能进一步促进已经高度接种的HCW人群的疫苗接种,尤其是当没有测试选项时。
UNASSIGNED: Seventeen states introduced COVID-19 vaccine mandates for health care workers (HCWs) in mid-2021. Prior research on the effect of these mandates was centered on the nursing home sector, and more evidence is needed for their effect on the entire HCW population.
UNASSIGNED: To examine the association between state COVID-19 vaccine mandates for HCWs and vaccine uptake in this population.
UNASSIGNED: This repeated cross-sectional study included biweekly, individual-level data for adults aged 25 to 64 years who were working or volunteering in health care settings obtained from the Household Pulse Survey between May 26 and October 11, 2021. Analyses were conducted between November 2022 and October 2023.
UNASSIGNED: Announcement of a state COVID-19 vaccine mandate for HCWs.
UNASSIGNED: An indicator for whether a sampled HCW ever received a COVID-19 vaccine and an indicator for whether an HCW completed or intended to complete the primary COVID-19 vaccination series. Event study analyses using staggered difference-in-differences methods compared vaccine uptake among HCWs in mandate and nonmandate states before and after each mandate announcement. The sample was further stratified by the availability of regular COVID-19 testing in place of a vaccination (ie, a test-out option) and by the ages of HCWs (25-49 or 50-64 years) to examine heterogeneous associations.
UNASSIGNED: The study sample included 31 142 HCWs (mean [SD] age, 45.5 [10.6] years; 72.1% female) from 45 states, 16 of which introduced COVID-19 vaccine mandates for HCWs. Results indicated a mandate-associated 3.46-percentage point (pp) (95% CI, 0.29-6.63 pp; P = .03) increase in the proportion of HCWs ever vaccinated against COVID-19 and a 3.64-pp (95% CI, 0.72-6.57 pp; P = .02) increase in the proportion that completed or intended to complete the primary vaccination series 2 weeks after mandate announcement from baseline proportions of 87.98% and 86.12%, respectively. In the stratified analyses, positive associations were only detected in mandate states with no test-out option and among HCWs aged 25 to 49 years, which suggested vaccination increases of 3.32% to 7.09% compared with baseline proportions.
UNASSIGNED: This repeated cross-sectional study found that state COVID-19 vaccine mandates for HCWs were associated with increased vaccine uptake among HCWs, especially among younger HCWs and those in states with no test-out option. These findings suggest the potential for vaccine mandates to further promote vaccinations in an already highly vaccinated HCW population, especially when no test-out option is in place.
