Expedited postpartum discharge during the COVID-19 pandemic and acute postpartum care utilization.

BACKGROUND: Early postpartum discharges increased organically during the COVID-19 pandemic. It is not known if this 'natural experiment' of shorter postpartum hospital stays resulted in increased risk for postpartum readmissions and other acute postpartum care utilization such as emergency room encounters. OBJECTIVE: The objectives of this study were to determine which clinical factors were associated with expedited postpartum discharge and whether the expedited postpartum discharge was associated with increased risk for acute postpartum care utilization. METHODS: This retrospective cohort study evaluated birth hospitalizations at affiliated hospitals during two periods: (i) the apex of the 'first wave' of the COVID-19 pandemic in New York City (3/22/20 to 4/30/20) and (ii) a historical control period of one year earlier (3/22/19 to 4/30/19). Routine postpartum discharge was defined as ≥2 d after vaginal birth and ≥3 d after cesarean birth. Expedited discharge was defined as <2 d after vaginal birth and <3 d after cesarean birth. Acute postpartum care utilization was defined as any emergency room visit, obstetric triage visit, or postpartum readmission ≤6 weeks after birth hospitalization discharge. Demographic and clinical variables were compared based on routine versus expedited postpartum discharge. Unadjusted and adjusted logistic regression models were performed to analyze factors associated with (i) expedited discharge and (ii) acute postpartum care utilization. Unadjusted (ORs) and adjusted odds ratios (aORs) with 95% CIs were used as measures of association. Stratified analysis was performed restricted to patients with chronic hypertension, preeclampsia, and gestational hypertension. RESULTS: A total of 1,358 birth hospitalizations were included in the analysis, 715 (52.7%) from 2019 and 643 (47.3%) from 2020. Expedited discharge was more common in 2020 than in 2019 (60.3% versus 5.0% of deliveries, p < .01). For 2020, clinical factors significantly associated with a decreased likelihood of expedited discharge included hypertensive disorders of pregnancy (OR 0.40, 95% CI 0.27-0.60), chronic hypertension (OR 0.14, 95% CI 0.06-0.29), and COVID-19 infection (OR 0.51, 95% CI 0.34-0.77). Cesarean (OR 3.00, 95% CI 2.14-4.19) and term birth (OR 3.34, 95% CI 2.03, 5.49) were associated with an increased likelihood of expedited discharge. Most of the associations retained significance in adjusted models. Expedited compared to routine discharge was not associated with significantly different odds of acute postpartum care utilization for 2020 deliveries (5.4% versus 5.9%; OR 0.92, 95% CI 0.47-1.82). Medicaid insurance (OR 2.30, 95% CI 1.06-4.98) and HDP (OR 5.16, 95% CI: 2.60-10.26) were associated with a higher risk of acute postpartum care utilization and retained significance in adjusted analyses. In the stratified analysis restricted to women with hypertensive diagnoses, expedited discharge was associated with significantly increased risk for postpartum readmission (OR 6.09, 95% CI 2.14, 17.33) but not overall acute postpartum care utilization (OR 2.17, 95% CI 1.00, 4.74). CONCLUSION: Expedited postpartum discharge was not associated with increased risk for acute postpartum care utilization. Among women with hypertensive diagnoses, expedited discharge was associated with a higher risk for readmission despite expedited discharge occurring less frequently.

Clinical and Demographic Risk Factors for COVID-19 during Delivery Hospitalizations in New York City.

OBJECTIVE: This study was aimed to review 4 weeks of universal novel coronavirus disease 2019 (COVID-19) screening among delivery hospitalizations, at two hospitals in March and April 2020 in New York City, to compare outcomes between patients based on COVID-19 status and to determine whether demographic risk factors and symptoms predicted screening positive for COVID-19. STUDY DESIGN: This retrospective cohort study evaluated all patients admitted for delivery from March 22 to April 18, 2020, at two New York City hospitals. Obstetrical and neonatal outcomes were collected. The relationship between COVID-19 and demographic, clinical, and maternal and neonatal outcome data was evaluated. Demographic data included the number of COVID-19 cases ascertained by ZIP code of residence. Adjusted logistic regression models were performed to determine predictability of demographic risk factors for COVID-19. RESULTS: Of 454 women delivered, 79 (17%) had COVID-19. Of those, 27.9% (n = 22) had symptoms such as cough (13.9%), fever (10.1%), chest pain (5.1%), and myalgia (5.1%). While women with COVID-19 were more likely to live in the ZIP codes quartile with the most cases (47 vs. 41%) and less likely to live in the ZIP code quartile with the fewest cases (6 vs. 14%), these comparisons were not statistically significant (p = 0.18). Women with COVID-19 were less likely to have a vaginal delivery (55.2 vs. 51.9%, p = 0.04) and had a significantly longer postpartum length of stay with cesarean (2.00 vs. 2.67days, p < 0.01). COVID-19 was associated with higher risk for diagnoses of chorioamnionitis and pneumonia and fevers without a focal diagnosis. In adjusted analyses, including demographic factors, logistic regression demonstrated a c-statistic of 0.71 (95% confidence interval [CI]: 0.69, 0.80). CONCLUSION: COVID-19 symptoms were present in a minority of COVID-19-positive women admitted for delivery. Significant differences in obstetrical outcomes were found. While demographic risk factors demonstrated acceptable discrimination, risk prediction does not capture a significant portion of COVID-19-positive patients. KEY POINTS: · COVID-19 symptoms were present in a minority of COVID-19-positive women admitted.. · COVID-19 symptomatology did not appear to differ before or after the apex of infection in New York.. · Demographic risk factors are unlikely to capture a significant portion of COVID-19-positive patients..
