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.

To examine the relation between maternal pre-delivery BMI and the accuracy of sonographic estimated fetal weight (EFW) in very preterm infants (<32 weeks gestation).
Methods
This retrospective study included singleton infants born between January 2010 and March 2023, at gestational ages 230 to 316 weeks, at a tertiary university-affiliated hospital. Absolute weight, percentage error, absolute percentage error, and overestimation and underestimation of EFW were compared between women with pre-delivery normal weight (BMI 18.5–24.99 kg/m2), overweight (BMI 25.0–29.99 kg/m2), and obesity (BMI >35.0 kg/m2). Multivariate linear regression analyses adjusted for potential confounders were performed to assess relations of maternal pre-conception and of pre-delivery BMI, with EFW accuracy.
Results
Included were 286 pregnancies. The absolute difference, percentage error, absolute percentage error, error within the 10% range, and underestimation or overestimation of EFW were similar between the groups. The multivariate linear regression analyses did not show significant associations of pre-conceptional BMI or of pre-delivery BMI with the percentage error. However, for small for gestational age compared to appropriate for gestational age fetuses, the percentage error was greater (8.9% vs. –0.6%, β = 0.35, P < 0.001) and the absolute percentage error was greater (11.0% vs. 6.7%, P < 0.001). Small for gestational age fetuses were at risk of fetal weight overestimation (percentage error exceeding 15%); OR 7.20 (95% CI 2.91–17.80).
Conclusions
Maternal pre-delivery BMI was not found to be related to EFW accuracy in very preterm infants. Nevertheless, EFW should be interpreted carefully, as it may underdiagnose poor fetal growth in this population.

The absolute difference, percentage error, absolute percentage error, error within the 10% range, and underestimation or overestimation of EFW were similar between the groups. The multivariate linear regression analyses did not show significant associations of pre-conceptional BMI or of pre-delivery BMI with the percentage error. However, for small for gestational age compared to appropriate for gestational age fetuses, the percentage error was greater (8.9% vs. –0.6%, β = 0.35, <em>P <</em> 0.001) and the absolute percentage error was greater (11.0% vs. 6.7%, <em>P <</em> 0.001). Small for gestational age fetuses were at risk of fetal weight overestimation (percentage error exceeding 15%); OR 7.20 (95% CI 2.91–17.80).</p></div><div><h3>Conclusions</h3><p>Maternal pre-delivery BMI was not found to be related to EFW accuracy in very preterm infants. Nevertheless, EFW should be interpreted carefully, as it may underdiagnose poor fetal growth in this population.</p></div>","PeriodicalId":16688,"journal":{"name":"Journal of obstetrics and gynaecology Canada","volume":"46 10","pages":"Article 102643"},"PeriodicalIF":2.0,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142108489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
