BACKGROUND/UNASSIGNED:With an increasing demand for critical care expertise and limitations in intensivist availability, innovative staffing models, such as the utilization of advanced practice providers (APPs), have emerged. OBJECTIVES/UNASSIGNED:The purpose of the study was to compare patient outcomes between APP and housestaff teams in the cardiac intensive care unit (CICU). METHODS/UNASSIGNED:This retrospective study, spanning March 2022 to July 2023, compares patient characteristics and outcomes between two CICU teams embedded in the same CICU at a large urban academic hospital: one staffed by housestaff and the other by APPs (80% physician assistants, 20% nurse practitioners) who each had approximately 1 to 2 years of experience in the CICU. The primary outcome was CICU mortality. Multivariable Cox regression analyses and Kaplan-Meier curves were used to assess the primary outcome. RESULTS/UNASSIGNED: < 0.0001). CONCLUSIONS/UNASSIGNED:Our moderately sized study demonstrated no difference in CICU or in-hospital mortality between patients managed by a housestaff team versus those managed by an APP team.

BACKGROUND:Our study aims to present clinical outcomes of mechanical thrombectomy (MT) in a safety-net hospital. METHODS:This is a retrospective study of intermediate or high-risk pulmonary embolism (PE) patients who underwent MT between October 2020 and May 2023. The primary outcome was 30-day mortality. RESULTS:Among 61 patients (mean age 57.6 years, 47% women, 57% Black) analyzed, 12 (19.7%) were classified as high-risk PE, and 49 (80.3%) were intermediate-risk PE. Of these patients, 62.3% had Medicaid or were uninsured, 50.8% lived in a high poverty zip code. The prevalence of normotensive shock in intermediate-risk PE patients was 62%. Immediate hemodynamic improvements included 7.4 mmHg mean drop in mean pulmonary artery pressure (-21.7%, p < 0.001) and 93% had normalization of their cardiac index postprocedure. Thirty-day mortality for the entire cohort was 5% (3 patients) and 0% when restricted to the intermediate-risk group. All 3 patients who died at 30 days presented with cardiac arrest. There were no differences in short-term mortality based on race, insurance type, citizenship status, or socioeconomic status. All-cause mortality at most recent follow up was 13.1% (mean follow up time of 13.4 ± 8.5 months). CONCLUSION:We extend the findings from prior studies that MT demonstrates a favorable safety profile with immediate improvement in hemodynamics and a low 30-day mortality in patients with acute PE, holding true even with relatively higher risk and more vulnerable population within a safety-net hospital.
