Hemorrhage Risk Assessment on Admission: Utility for Prediction of Maternal Morbidity.

OBJECTIVE: Hemorrhage is a major cause of maternal morbidity and mortality prompting creation of innovative risk assessment tools to identify patients at highest risk. We aimed to investigate the association of hemorrhage risk assessment with maternal morbidity and to evaluate maternal outcomes after implementation of the risk assessment across hospital sites. STUDY DESIGN: We conducted a retrospective cohort analysis of a multicenter database including women admitted to labor and delivery from January 2015 to June 2018. The Association of Women's Health, Obstetric and Neonatal Nurses risk assessment tool was used to categorize patients as low, medium, or high risk for hemorrhage. Multivariate logistic regression was used to describe the association between hemorrhage risk score and markers of maternal morbidity and evaluate maternal outcomes before and after standardized implementations of the risk assessment tool. RESULTS: In this study, 14,861 women were categorized as low risk (26%), 26,080 (46%) moderate risk, and 15,730 (28%) high risk (N = 56,671 births). For women with high-risk scores, the relative risk (RR) ratio compared with low-risk women was 4.9 (RR: 95% confidence interval [CI]: 3.2-7.4) for blood transfusion and 5.2 (RR: 95% CI: 4.6-5.9) for estimated blood loss (EBL) ≥ 1,000 mL. For the second objective, 110,633 women were available for pre- and postimplementation analyses (39,027 and 71,606, respectively). A 20% reduction in rates of blood transfusion (0.5-0.4%, p = 0.02) and EBL ≥ 1,000 mL (6.3-5.9%, p = 0.014) was observed between pre- and postimplementations of the admission hemorrhage risk assessment tool. CONCLUSION: Women who were deemed high risk for hemorrhage using a hemorrhage risk assessment tool had five times higher risk for blood transfusion and EBL ≥ 1,000 mL compared with low-risk women. Given the low incidence of the outcomes explored, the hemorrhage risk assessment works moderately well to identify patients at risk for peripartum morbidity. KEY POINTS: · This study aimed to understand the utility of the AWOHNN hemorrhage risk assessment tool for predicting hemorrhage-related morbidity and to evaluate maternal outcomes before and after tool implementations.. · A high score using a hemorrhage risk assessment tool on admission is associated with five times higher risk for blood transfusion and/or estimated blood loss ≥ 1,000 mL, compared with a low score.. · Use of a hemorrhage risk assessment tool works moderately well to identify patients at highest risk for hemorrhage-related morbidity..

Retrospective Cohort Study of Rates of Return Emergency Department Visits Among Patients Transported Home by Ambulance.

BACKGROUND: Emergency Medical Services (EMS) is an important resource that interacts with our most vulnerable patients during transport home after hospital discharge. EMS providers may be appropriately situated to support the transition of care to the home environment. OBJECTIVES: This study aimed to determine whether patients transported home by ambulance experience higher rates of return emergency department (ED) visits and readmission compared with similar patients transported home by other means. METHODS: This was a retrospective cohort study conducted at a U.S. tertiary care academic hospital. Patients aged 65 years and over transported home via ambulance after hospital discharge between January and March 2012 were included. Rates of 72-h and 30-day ED revisits and 30-day hospital readmissions were calculated. Odds ratios were calculated and revisit rates between groups were compared. RESULTS: There were 207 patients aged 65 and over transported home by ambulance. Matched controls were found for 162 patients. Compared with the matched controls, the exposed group experienced a statistically significant higher rate of 30-day ED returns (18.519% vs. 10.494%; odds ratio [OR] 1.939; p = 0.043). The exposed group also experienced a higher rate of 72-h ED returns (2.469% vs. 0.617%; OR 4.076) and 30-day readmissions (12.346% vs. 6.173%; OR 2.141), though results did not reach statistical significance. CONCLUSION: The study findings suggest that transport home via ambulance after hospital discharge could be predictive of a high risk of recidivism independent of established readmission risk factors. Programs that expand the role of EMS to include post-transport interventions may warrant further exploration.
