ABSTRACT
BACKGROUND: Limited hospital inpatient capacity, exacerbated by SARS-CoV-2 (COVID-19) and associated staffing shortages, has driven interest in converting surgeries historically done as inpatient procedures to same-day surgeries (SDS). Remote patient monitoring (RPM) has the potential to increase safety and confidence in SDS but has had mixed success in a bariatric population. OBJECTIVES: Assess the feasibility of and adherence to a protocol offering patients same-day laparoscopic sleeve gastrectomy (SG) supported by RPM with an updated wearable device. Secondary outcomes were readmissions, costs, adherence, and clinical alarm rates. SETTING: Academic, military tertiary referral center (United States). METHODS: A single-center, retrospective case control study of patients undergoing SG, comparing SDS with RPM to patients admitted to the hospital for SG during this time. Patients for SDS were selected by set inclusion/exclusion criteria and patient/surgeon preference, and perioperative management was standardized. RESULTS: Twenty patients were enrolled in the SDS group, then compared with 53 inpatients. Inpatients were older (46 versus 39, P = .006), but with no significant differences in sex, preoperative body mass index, or co-morbidities. RPM wearable and blood pressure adherence was found to be 97% and 80%, respectively. Readmission rates were similar (10% versus 7.5%, P > .05). RPM alarm rates were .5 (0-1.3) per patient for each 24-hour home monitoring period. SDS patients also demonstrated the potential for cost savings over inpatient SG, depending on the number of patients monitored per day as well as the healthcare setting. CONCLUSIONS: SG as SDS with RPM was a feasible approach. It should be evaluated in other surgical procedures and higher-risk patient populations.

ABSTRACT
BACKGROUND: Virtual care (VC) and remote patient monitoring programs were deployed widely during the COVID-19 pandemic. Deployments were heterogeneous and evolved as the pandemic progressed, complicating subsequent attempts to quantify their impact. The unique arrangement of the US Military Health System (MHS) enabled direct comparison between facilities that did and did not implement a standardized VC program. The VC program enrolled patients symptomatic for COVID-19 or at risk for severe disease. Patients' vital signs were continuously monitored at home with a wearable device (Current Health). A central team monitored vital signs and conducted daily or twice-daily reviews (the nurse-to-patient ratio was 1:30). OBJECTIVE: Our goal was to describe the operational model of a VC program for COVID-19, evaluate its financial impact, and detail its clinical outcomes. METHODS: This was a retrospective difference-in-differences (DiD) evaluation that compared 8 military treatment facilities (MTFs) with and 39 MTFs without a VC program. Tricare Prime beneficiaries diagnosed with COVID-19 (Medicare Severity Diagnosis Related Group 177 or International Classification of Diseases-10 codes U07.1/07.2) who were eligible for care within the MHS and aged 21 years and or older between December 2020 and December 2021 were included. Primary outcomes were length of stay and associated cost savings; secondary outcomes were escalation to physical care from home, 30-day readmissions after VC discharge, adherence to the wearable, and alarms per patient-day. RESULTS: A total of 1838 patients with COVID-19 were admitted to an MTF with a VC program of 3988 admitted to the MHS. Of these patients, 237 (13%) were enrolled in the VC program. The DiD analysis indicated that centers with the program had a 12% lower length of stay averaged across all COVID-19 patients, saving US $2047 per patient. The total cost of equipping, establishing, and staffing the VC program was estimated at US $3816 per day. Total net savings were estimated at US $2.3 million in the first year of the program across the MHS. The wearables were activated by 231 patients (97.5%) and were monitored through the Current Health platform for a total of 3474 (median 7.9, range 3.2-16.5) days. Wearable adherence was 85% (IQR 63%-94%). Patients triggered a median of 1.6 (IQR 0.7-5.2) vital sign alarms per patient per day; 203 (85.7%) were monitored at home and then directly discharged from VC; 27 (11.4%) were escalated to a physical hospital bed as part of their initial admission. There were no increases in 30-day readmissions or emergency department visits. CONCLUSIONS: Monitored patients were adherent to the wearable device and triggered a manageable number of alarms/day for the monitoring-team-to-patient ratio. Despite only enrolling 13% of COVID-19 patients at centers where it was available, the program offered substantial savings averaged across all patients in those centers without adversely affecting clinical outcomes.
