Outcomes in patients requiring repeat extracorporeal membrane oxygenation

Background

As the number of patients requiring extracorporeal membrane oxygenation (ECMO) increases nationwide, many patients may require ECMO more than once. We review our experience and outcomes in patients requiring repeat ECMO support.

Methods

The Nebraska ECMO Research Database was utilized for data analysis, and repeat ECMO patients (REPs) were compared to the overall ECMO population.

Results

Of 246 patients, 2.4% (6/246) were REPs. There was no statistical difference between the median days of initial support run (P = 0.670) and second support run (P = 0.813) for REPs when comparing to the non‐REP population. Median hospital length of stay for REPs was 53 days (16‐124) compared to the non‐REPs, who had a median hospital length of stay of 22 days (1‐270); P = 0.043. In‐hospital mortality rate for REPs was 50% (3/6) and 50% for non‐REPs (120/240). Survival 30 days postdischarge for REPs was 50% (3/6) compared to non‐REPs at 48.3% (116/240); P = NS.

Conclusions

Outcomes for repeat ECMO patients compare favorably to the overall ECMO population and suggest a need to explore and broaden the clinical indications for repeat ECMO.     

Reducing Disparities in Postpartum Care Utilization: Development of a Clinical Risk Assessment Tool

Introduction

Patients receiving care at Federally Qualified Health Centers (FQHCs) have low postpartum care attendance. Perinatal morbidity and mortality disproportionately affect patients with low-income and are potentially preventable. The purpose of this study was to develop a clinical decision support tool to identify FQHC patients less likely to return for postpartum care. To accomplish this purpose, we evaluated established predictors and novel risk factors in our patient population.

Methods

This is a retrospective, secondary data analysis of 50,022 patients who received prenatal care past 24 weeks’ gestation in FQHCs between 2012 and 2017. The postpartum visit was defined using Healthcare Effectiveness Data and Information Set measures as early care (birth to 21 days) and later care (21-84 days). Anderson's Behavioral Model for Access to Healthcare guided inclusion of potentially predictive factors. We stratified data by postpartum care attendance, and a final predictive model was selected by model fit statistics and clinical relevance.

Results

In our sample, 64% of birthing persons attended postpartum care at FQHCs. Of those who returned for care, 38% returned within 21 days postbirth and 62% returned between 21 and 84 days, with 28% returning for both early and later care. Predictors for postpartum care attendance included maternal age, parity, gestational age at first visit, and number of prenatal care visits. A clinical decision support tool for identifying patients less likely to return for care was created.

Discussion

An easy to implement clinical decision support tool can help identify FQHC patients at risk for postpartum nonattendance. Future interventions to improve adequacy of prenatal care can encourage early entry into prenatal care and sufficient prenatal visits. These efforts may improve postpartum care attendance and maternal health.
