Hospital Admission Rates and Mortality Among Emergency Department Patients with COVID-19 Discharged with Remote Patient Monitoring with or without HO2ME - A Value-Based Approach.

Abstract

Background: The pandemic caused by the novel Coronavirus 2019 (COVID-19) overwhelmed healthcare systems with emergency department (ED) and hospital overcrowding. Our hospital system was able to discharge a subset of COVID-19 patients home with remote patient monitoring (RPM) and home oxygen (HO₂ME) if needed, which opened up beds for the more critical patients. The objective of this study was to review the all-cause 30-day mortality and admission rates for patients chosen for our program, and to additionally examine the financial impact.

Methods: This was a retrospective cohort study of ED patients who were included if they tested positive for SARS-CoV-2 RNA on nasopharyngeal swab and received emergency care for COVID-19 at any INTEGRIS facility during 10/27/2020-9/8/2021. For the primary statistical analysis, descriptive statistics were calculated and reported as medians with interquartile ranges. For the purpose of financial analysis, we filtered a subset of insured patients who were sent home with oxygen.

Results: 490 patients were enrolled with a median age of 62 and median body mass index (BMI) of 31. Of the 490 patients, 151 patients (31%) met requirements for home oxygen and were discharged with oxygen. Over a median enrollment time of 15 days, patients discharged from the emergency department on the RPM program were observed to have an all-cause 30-day mortality rate of 3.2% (95% Cl, 1.8%-5.2%). The observed rate of all-cause hospital admission within 30 days was 17%. The financial analysis revealed savings to insurance companies.

Conclusions: This study demonstrated that rapidly deploying a RPM program for patients with acute COVID-19 infection allowed our health system to safely care for patients in their homes. The program opened hospital beds for more severe and critically ill COVID-19 patients who necessitated more intense monitoring and inpatient care, while simultaneously observing low 30-day all-cause mortality and hospital admission rates.
