Evaluating Racial/Ethnic Differences in Care Escalation Among COVID-19 Patients in a Home-Based Hospital.

The novel coronavirus disease 2019 (COVID-19) has infected over 414 million people worldwide with 5.8 million deaths, as of February 2022. Telemedicine-based interventions to expand healthcare systems' capacity and reduce infection risk have rapidly increased during the pandemic, despite concerns regarding equitable access. Atrium Health Hospital at Home (AH-HaH) is a home-based program that provides advanced, hospital-level medical care and monitoring for patients who would otherwise be hospitalized in a traditional setting. Our retrospective cohort study of positive COVID-19 patients who were admitted to AH-HaH aims to investigate whether the rate of care escalation from AH-HaH to traditional hospitalization differed based on patients' racial/ethnic backgrounds. Logistic regression was used to examine the association between care escalation within 14 days from index AH-HaH admission and race/ethnicity. We found approximately one in five patients receiving care for COVID-19 in AH-HaH required care escalation within 14 days. Odds of care escalation were not significantly different for Hispanic or non-Hispanic Blacks compared to non-Hispanic Whites. However, secondary analyses showed that both Hispanic and non-Hispanic Black patients were younger and with fewer comorbidities than non-Hispanic Whites. The study highlights the need for new care models to vigilantly monitor for disparities, so that timely and tailored adaptations can be implemented for vulnerable populations.

Care innovations and health disparities: An exploration of COVID-19 outcomes in inpatient and hospital-at-home care settings

Background: Hospital at home (HaH) programs have been a critical resource for providing inpatient care to acutely ill patients throughout the COVID-19 pandemic. Given that this innovative care delivery model relies on technology and environmental concerns, questions have been raised about the effectiveness of HaH for vulnerable groups. However, evidence is extremely limited regarding equity issues in the HaH context. Thus, we explored COVID-19 outcomes within vulnerable groups. Methods: We conducted a matched, retrospective study of 116 acutely ill patients with COVID-19, aged ≥18 years, who presented to an AH emergency department (ED) and were admitted for inpatient care. Treatment patients were admitted to AH HaH between July 15 and September 31, 2020, and control patients were hospitalized between May 8 and June 25, 2020. Patients were matched based on oxygen requirement and DS CRB-65 (DEFINE) score. Race or ethnicity and area deprivation index (ADI) were chosen as predictors of health disparities. The ADI incorporates 17 indicators of poverty, educational attainment, and housing quality at the census tract level. Outcomes included 30-day (from discharge) severe illness or death composite, IP readmission, and ED visit. Results: The frequency of 30-day severe illness or death and ED visits were equivalent between the groups (n = 11;ED n = 5);the proportion of severe illness was higher for White patients in AH-HaH (n = 9 vs n = 5), and for Hispanic patients treated in the hospital (n = 5 vs n = 0;Fig. 1). There were no 30-day inpatient readmissions in the AH-HaH group, but 8 readmissions occurred with inpatients. The distribution of severe illness among the ADI quintiles varied. For traditional inpatients, disease progression was limited to ADI Q3–5 (Q3 = 3, Q4 = 6, Q5 = 2);for AH-HaH patients, disease progression was not influenced by ADI. The effect of ADI on 30-day ED readmission was nonsignificant. Conclusions: Although exploratory in nature, the results suggest that HaH may help combat sources of health disparities that have dominated the pandemic. Although inpatient care resulted in inpatient readmissions, mainly among Black and Hispanic patients, AH-HaH stays were not associated with any inpatient readmissions. The equivalent distribution among ADI quintiles of patients who became severely ill within 30 days of their AH-HaH stay suggests that HaH may be able to leverage innovation to reach vulnerable populations and reduce the impact of factors that contribute to inequity.Funding: NoneDisclosures: None

The Virtual Hospital: An Innovative Solution for Disaster Response.

Like any disaster, the COVID-19 pandemic has presented significant challenges to healthcare systems, especially the threat of insufficient bed capacity and resources. Hospitals have been required to plan for and implement innovative approaches to expand hospital inpatient and intensive care capacity. This article presents how one of the largest healthcare systems in the United States leveraged existing technology infrastructure to create a virtual hospital that extended care beyond the walls of the "brick and mortar" hospital.

Insights From Rapid Deployment of a "Virtual Hospital" as Standard Care During the COVID-19 Pandemic.

BACKGROUND: Pandemics disrupt traditional health care operations by overwhelming system resource capacity but also create opportunities for care innovation. OBJECTIVE: To describe the development and rapid deployment of a virtual hospital program, Atrium Health hospital at home (AH-HaH), within a large health care system. DESIGN: Prospective case series. SETTING: Atrium Health, a large integrated health care organization in the southeastern United States. PATIENTS: 1477 patients diagnosed with coronavirus disease 2019 (COVID-19) from 23 March to 7 May 2020 who received care via AH-HaH. INTERVENTION: A virtual hospital model providing proactive home monitoring and hospital-level care through a virtual observation unit (VOU) and a virtual acute care unit (VACU) in the home setting for eligible patients with COVID-19. MEASUREMENTS: Patient demographic characteristics, comorbid conditions, treatments administered (intravenous fluids, antibiotics, supplemental oxygen, and respiratory medications), transfer to inpatient care, and hospital outcomes (length of stay, intensive care unit [ICU] admission, mechanical ventilation, and death) were collected from electronic health record data. RESULTS: 1477 patients received care in either the AH-HaH VOU or VACU or both settings, with a median length of stay of 11 days. Of these, 1293 (88%) patients received care in the VOU only, with 40 (3%) requiring inpatient hospitalization. Of these 40 patients, 16 (40%) spent time in the ICU, 7 (18%) required ventilator support, and 2 (5%) died during their hospital admission. In total, 184 (12%) patients were ever admitted to the VACU, during which 21 patients (11%) required intravenous fluids, 16 (9%) received antibiotics, 40 (22%) required respiratory inhaler or nebulizer treatments, 41 (22%) used supplemental oxygen, and 24 (13%) were admitted as an inpatient to a conventional hospital. Of these 24 patients, 10 (42%) required ICU admission, 1 (3%) required a ventilator, and none died during their hospital admission. LIMITATION: Generalizability is limited to patients with a working telephone and the ability to comply with the monitoring protocols. CONCLUSION: Virtual hospital programs have the potential to provide health systems with additional inpatient capacity during the COVID-19 pandemic and beyond. PRIMARY FUNDING SOURCE: Atrium Health.
