Postpartum Maternal and Neonatal Hospitalizations Among Women with HIV: A Population-Based Study

Differences in Healthcare Utilization in Women with and without Inflammatory Bowel Diseases During Preconception, Pregnancy and Postpartum: A Population-Based Cohort Study

BACKGROUND AND AIMS

Compared to those without inflammatory bowel disease [IBD], women with IBD may have increased healthcare utilization during pregnancy and postpartum, though this remains to be confirmed. We aimed to characterize this healthcare use between these groups.

METHODS

Administrative databases were accessed to identify women [aged 18-55 years] with and without IBD who had a live, singleton pregnancy between 2003 and 2018. Differences in emergency department [ED] visits, hospitalizations and prenatal care during 12 months preconception, pregnancy and 12 months postpartum were characterized. Multivariable negative binomial regression was performed to report incidence rate ratios [IRRs] with 95% confidence intervals [95% CIs]. Covariates included maternal age at conception, location of residence, socioeconomic status and maternal comorbidity.

RESULTS

In total, 6163 women with IBD [9158 pregnancies] and 1091 013 women without IBD [1729 411 pregnancies] were included. Women with IBD were more likely to visit the ED [IRR 1.13, 95% CI 1.08-1.18] and be hospitalized [IRR 1.11, 95% CI 1.01-1.21] during pregnancy, and visit the ED [IRR 1.21, 95% CI 1.15-1.27] and be hospitalized [IRR 1.18, 95% CI 1.05-1.32] during postpartum. On unadjusted analysis, women with IBD were more likely to be hospitalized for venous thromboembolic events. There was no difference in healthcare use in preconception. Finally, women with IBD also had a greater number of prenatal visits during pregnancy and were more likely to receive a first-trimester prenatal visit.

CONCLUSION

Women with IBD have increased healthcare utilization during pregnancy and postpartum. Efforts should be made to increase ambulatory care access during this period, which in turn may reduce this health-services utilization.

Risk factors associated with 31-day unplanned hospital readmission in newborns: a systematic review

The purpose of this study is to synthesize evidence on risk factors associated with newborn 31-day unplanned hospital readmissions (UHRs). A systematic review was conducted searching CINAHL, EMBASE (Ovid), and MEDLINE from January 1st 2000 to 30th June 2021. Studies examining unplanned readmissions of newborns within 31 days of discharge following the initial hospitalization at the time of their birth were included. Characteristics of the included studies examined variables and statistically significant risk factors were extracted from the inclusion studies. Extracted risk factors could not be pooled statistically due to the heterogeneity of the included studies. Data were synthesized using content analysis and presented in narrative and tabular form. Twenty-eight studies met the eligibility criteria, and 17 significant risk factors were extracted from the included studies. The most frequently cited risk factors associated with newborn readmissions were gestational age, postnatal length of stay, neonatal comorbidity, and feeding methods. The most frequently cited maternal-related risk factors which contributed to newborn readmissions were parity, race/ethnicity, and complications in pregnancy and/or perinatal period.

CONCLUSION

This systematic review identified a complex and diverse range of risk factors associated with 31-day UHR in newborn. Six of the 17 extracted risk factors were consistently cited by studies. Four factors were maternal (primiparous, mother being Asian, vaginal delivery, maternal complications), and two factors were neonatal (male infant and neonatal comorbidities). Implementation of evidence-based clinical practice guidelines for inpatient care and individualized hospital-to-home transition plans, including transition checklists and discharge readiness assessments, are recommended to reduce newborn UHRs.

WHAT IS KNOWN

• Attempts have been made to identify risk factors associated with newborn UHRs; however, the results are inconsistent.

WHAT IS NEW

• Six consistently cited risk factors related to newborn 31-day UHRs. Four maternal factors (primiparous, mother being Asian, vaginal delivery, maternal complications) and 2 neonatal factors (male infant and neonatal comorbidities). • The importance of discharge readiness assessment, including newborn clinical fitness for discharge and parental readiness for discharge. Future research is warranted to establish standardised maternal and newborn-related variables which healthcare providers can utilize to identify newborns at greater risk of UHRs and enable comparison of research findings.

Patterns of cesarean birth among women living with HIV in Ontario: A cross-sectional, population-level study

BACKGROUND

In Canada, as is found globally, women of reproductive age are a growing demographic of persons living with HIV. Combination antiretroviral therapy (cART) treatment enables women living with HIV (WLWH) to become pregnant without perinatal transmission, and they are increasingly planning to become pregnant. Since 2014, Canadian guidelines no longer recommend routine elective cesarean birth (CB) for women who are virally suppressed and receiving cART. It is unknown whether their obstetric care has changed since this update. Our objective was to describe trends in cesarean births among WLWH in Ontario, Canada, over a 12-year period.

METHODS

Our research is co-led and codesigned with WLWH. We conducted a retrospective population-level cohort study using linked health administrative databases at ICES (formally, the Institute for Clinical and Evaluative Sciences). Participants were all women who gave birth in Ontario, between 2006/07 and 2017/18. We assessed their intrapartum characteristics and used multivariable regression to determine an association between HIV status and CB, controlling for sociodemographic and clinical variables.

RESULTS

Since 2014, the overall proportion of CB among WLWH remained stable and was higher than among women without HIV (39.9% vs 29.0%, P < 0.001). In addition, the proportion of primary CB decreased between 2006 and 2010 and between 2014 and 2018 (28.5%-19.3%), whereas the proportion of repeat CB increased (13.1%-20.5%, P = 0.013).

CONCLUSIONS

Because of decreasing HIV-related indications for CB, more practitioners may be following the guidelines for first-time mothers. Currently, no guidelines exist for care of WLWH with a previous CB, and opportunities for vaginal birth may be missed in this population.

Determinants of adverse neonatal outcomes among postnatal women in Dar es Salaam -Tanzania

BACKGROUND

Neanatal comploications are the commonest problems facing babies in Tanzania. An attempt has been made to investigate determinants of neonatal outcomes among postnatal women.

METHODS

Using a case-contrrol study design, 165 women were selected from 3 health facilities, where they had had antenatal care (ANC), labour, delivery and post natal care.

RESULTS

Chi- square test revealed that gestational age (p-value, 0.01), HIV status (p-value, 0.000) and malaria (p-value, 0.001<0.05) were significantly associated with adverse neonatal outcomes.

CONCLUSION

The study concluded that implementation of community-based intervention is needed to ensure survival of newborns.

HIV Infection and risk of postpartum infection, complications and mortality in rural Uganda

HIV infection may increase risk of postpartum infection and infection-related mortality. We hypothesized that postpartum infection incidence and attributable mortality in Mbarara, Uganda would be higher in HIV-infected than HIV-uninfected women. We performed a prospective cohort study of 4231 women presenting to a regional referral hospital in 2015 for delivery or postpartum care. All febrile or hypothermic women, and a subset of randomly selected normothermic women were followed during hospitalization and with 6-week postpartum phone interviews. The primary outcome was in-hospital postpartum infection. Secondary outcomes included in-hospital complications (mortality, re-operation, intensive care unit transfer, need for imaging or blood transfusion) and 6-week mortality. We performed multivariable regression analyses to estimate adjusted differences in each outcome by HIV serostatus. Mean age was 25.2 years and 481 participants (11%) were HIV-infected. Median CD4+ count was 487 (IQR 325, 696) cells/mm³, and 90% of HIV-infected women (193/215 selected for in-depth survey) were on antiretroviral therapy. Overall, 5% (205/4231) of women developed fever or hypothermia. Cumulative in-hospital postpartum infection incidence was 2.0% and did not differ by HIV status (aOR 1.4, 95% CI 0.6-3.3, P = 0.49). However, more HIV-infected women developed postpartum complications (4.4% vs. 1.2%, P = 0.001). In-hospital mortality was rare (2/1768, 0.1%), and remained so at 6 weeks (4/1526, 0.3%), without differences by HIV serostatus (P = 1.0 and 0.31, respectively). For women in rural Uganda with high rates of antiretroviral therapy coverage, HIV infection did not predict postpartum infection or mortality, but was associated with increased risk of postpartum complications.
