摘要

目的:在孕妇接受产前检查时接种疫苗可提高疫苗接种率。在加拿大,产前检查时接种流感疫苗并非标准做法。自 2016-2017 年流感季节起,孕妇可在阿尔伯塔省卡尔加里市一家城市诊所的护理点 (POC) 接种流感疫苗。本研究的目的是描述性地检查多个流感季节中POC-孕期疫苗接种(VIP)干预措施的疫苗接种率,并描述流感疫苗覆盖率与合并症和地区社会经济状况之间的关联:我们采用前后对比的研究设计,对连续六个流感季节的疫苗接种率进行了调查:其中两个季节是在实施 POC-VIP 之前(2014-2015 年和 2015-2016 年),四个季节是在实施 POC-VIP 之后(2016-2017 年至 2019-2020 年)。我们利用临床和行政数据库确定了出生队列并测量了流感疫苗的接种率。计算流感疫苗接种率,并使用费雪精确检验进行比较,统计学意义为 P 值 0.05 结果:研究期间共确定了 4443 例妊娠。与干预前流感季节每 1000 患者周 11.7 的接种率相比,干预年的流感疫苗接种率有所上升,达到每 1000 患者周 40.1(P < 0.001)。在大多数季节,有或没有合并症的孕妇之间的疫苗接种率没有统计学差异。疫苗接种率随着干预前几年物质匮乏程度的增加而下降:结论:与干预前相比,干预年的疫苗接种率更高。在这项研究中,我们采用了系统的方法来检查孕期疫苗接种率,并对 POC-VIP 干预措施进行了描述性检查。

Improving Influenza Vaccine Uptake During Pregnancy Through Vaccination at Point of Care: A Before-and-After Study

Objectives

Vaccine administration where pregnant individuals receive prenatal care may increase vaccine coverage. Availability of influenza vaccine at prenatal care visits is not standard in Canada. Since the 2016–2017 influenza season, pregnant individuals can receive the influenza vaccine at the point of care (POC) in an urban clinic in Calgary, Alberta. The objective of this study was to descriptively examine vaccination rates across multiple influenza seasons for a POC vaccination in pregnancy (VIP) intervention and describe associations between influenza vaccine coverage and comorbidities and area-level socioeconomic status.

Methods

A before-and-after study design was used to examine vaccine coverage across 6 consecutive influenza seasons: 2 before (2014–2015 and 2015–2016) and 4 after POC-VIP implementation (2016–2017 to 2019–2020). We identified the birth cohort and measured influenza vaccine uptake using clinical and administrative databases. Influenza vaccination rates were computed and compared using the Fisher exact test with statistical significance at a P value of 0.05.

Results

A total of 4443 pregnancies were identified during the study period. The influenza vaccination rate increased in the intervention years at 40.1 per 1000 patient-weeks (P < 0.001), compared to the pre-intervention influenza seasons at 11.7 per 1000 patient-weeks. Vaccine coverage did not statistically differ between pregnancies with or without comorbidities across most seasons. Vaccine coverage decreased as material deprivation increased in pre-intervention years.

Conclusions

The vaccination rate was higher in the intervention years compared to the pre-intervention period. In this study, we applied a systematic methodology to examine vaccine coverage in pregnancy and presented a descriptive examination of a POC-VIP intervention.
