An outpatient model of care for COVID-19 infected kidney transplant patients - The hospital-at-home.

Background: The COVID-19 pandemic is protracted and episodic surges from viral variants continue to place significant strain on healthcare systems. COVID-19 vaccines, antiviral therapy and monoclonal antibodies have significantly reduced COVID-19 associated morbidity and mortality. Concurrently, telemedicine has gained acceptance as a model of care and a tool for remote monitoring. These advances allow us to safely transit our inpatient-based care for COVID-19 infected kidney transplant recipients (KTRs) to a hospital-at-home (HaH) model of care.

Methods: KTRs with PCR-proven COVID-19 infection were triaged by teleconsult and laboratory tests. Suitable patients were enrolled into the HaH. Remote monitoring via teleconsults were conducted daily until patients were de-isolated based on a time-based criterion. Monoclonal antibodies were administered in a dedicated clinic where indicated.

Results: Eighty-one KTRs with COVID-19 were enrolled into the HaH between February and June 2022, 70 (86.4%) completed HaH recovery without complications. Eleven (13.6%) patients required inpatient hospitalization for medical issues (n = 8) and weekend monoclonal antibody infusion (n = 3). Patients requiring inpatient hospitalization had longer transplant vintage (15 years vs. 10 years, p = .03), anaemia (haemoglobin 11.6 g/dL vs. 13.1 g/dL, p = .01), lower eGFR (39.8 vs. 62.9 mL/min/1.73 m , p < .05) and lower RBD levels (<50 AU/mL vs. 1435 AU/mL, p = .02). HaH saved 753 inpatient patient-days with no deaths observed. Hospital admission rates from the HaH programme was 13.6%. Patients who required inpatient care had direct access admission without utilization of emergency department resources.

Conclusion: Selected KTRs with COVID-19 infection can be safely managed in a HaH programme; alleviating strain on inpatient and emergency healthcare resources.
