RESUMEN
OBJECTIVE: Postpartum hemorrhage (PPH) protocols improve patient safety and reduce utilization of blood products; however, few data exist on sustainability of PPH checklist use, how use affects care delivery, and variation of use among patient subgroups. This study aimed to (1) examine compliance with PPH checklist use during vaginal deliveries, (2) evaluate whether checklist use varied by patient and/or care team characteristics, and (3) evaluate whether checklist use was associated with increased use of recommended medications/interventions. STUDY DESIGN: This was a quality improvement study performed from April 2021 through June 2023. A multidisciplinary team developed a revised PPH checklist and used quality improvement methodology to increase checklist use following vaginal birth. Data were collected from medical records and clinician survey. Control charts were generated to track checklist use and evaluate special cause variation. Chi-square tests and logistic regression were used to evaluate variation in medications/interventions and across subgroups. RESULTS: During the study period, there were 342 cases of PPH at the time of vaginal birth. The checklist was used in 67% of PPH cases during the 20-month period after implementation in a setting where no checklist was previously being used. We found no statistically significant differences in checklist use by patient or health care team characteristics. Use of tranexamic acid, carboprost, and misoprostol were significantly associated with checklist use. CONCLUSION: This study demonstrated successful implementation of a checklist protocol where no checklist was previously being used, with sustained use in an average of 67% of PPH cases over 20 months. Checklist use was consistent across subgroups and was associated with higher use of interventions shown to lower blood loss. KEY POINTS: · Our study showed sustainability of PPH checklist use over a 20-month period.. · PPH checklist use was associated with increased use of interventions known to reduce blood loss.. · Checklist was used consistently across patient subgroups; may help address inequities in obstetric outcomes..
RESUMEN
OBJECTIVE: Our objective was to evaluate whether hemoglobin on admission for childbirth is associated with postpartum acute care use (ACU). STUDY DESIGN: We conducted a retrospective cohort study of patients giving birth at a southeastern quaternary care hospital from January 2018 through June 2021 using electronic health records. Predelivery hemoglobin was categorized as <9, 9- < 10, 10- < 11, 11- < 12, and ≥12 g/dL. Acute care was defined as a visit to obstetric triage, the emergency department, or inpatient admission within 90 days postpartum. Generalized estimating equations quantified the crude and multivariable-adjusted association between predelivery hemoglobin and ACU. RESULTS: Among 8,677 pregnancies, 1,467 (17%) used acute care in the system within 90 days postpartum. In unadjusted models, those with predelivery hemoglobin <9 had twice the risk of postpartum ACU compared to those with hemoglobin ≥12 (95% confidence interval [CI]: 1.59-2.69), with a decrease in risk for each increase in hemoglobin category (9- < 10 g/dL: risk ratio [RR]: 1.47, CI: 1.21-1.79; 10- < 11 g/dL: RR: 1.44, CI: 1.26-1.64; 11- < 12 g/dL: RR: 1.20, CI: 1.07-1.34). The adjusted model showed a similar trend with smaller effect estimates (<9 g/dL: RR: 1.50, CI: 1.14-1.98; 9- < 10 g/dL: RR: 1.22, CI: 1.00-1.48; 10- < 11 g/dL: RR: 1.22, CI: 1.07-1.40; 11- < 12 g/dL: RR: 1.09, CI: 0.98-1.22). CONCLUSION: Low hemoglobin at childbirth admission was associated with increased postpartum ACU. Low hemoglobin on admission could signal to providers that additional follow-up, resources, and ongoing support are warranted to identify and address underlying health needs. Because hemoglobin is routinely assessed during the childbirth hospitalization, this indicator may be especially valuable for risk assessment among patients with limited prior engagement in health care. KEY POINTS: · Low hemoglobin on admission for birth is associated with postpartum acute care use.. · Hemoglobin on admission may aid in risk-stratification during childbirth hospitalization.. · Point-of-care metrics may help identify high-risk patients with limited preventive health care..
