Site of care and factors associated with mortality in unvaccinated Australian aged care residents during COVID-19 outbreaks.

BACKGROUND: Residential InReach presents an alternative to hospital admission for aged care residents swabbed for coronavirus disease 2019 (COVID-19), although relative outcomes remain unknown. AIMS: To compare rates and predictors of 28-day mortality for aged care residents seen by InReach with COVID-19, or 'suspected COVID-19' (sCOVID), including hospital versus InReach-based care. METHODS: Prospective observational study of consecutive patients referred to a Victorian InReach service meeting COVID-19 testing criteria between April and October 2020 (prevaccine availability). COVID-19 was determined by positive polymerase chain reaction testing on nasopharyngeal swab. sCOVID-19 was defined as meeting symptomatic Victorian Government testing criteria but persistently swab negative. RESULTS: There were no significant differences in age, sex, Clinical Frailty Score (CFS) or Charlson Comorbidity Index (CCI) between 152 patients with COVID-19 and 118 patients with sCOVID. Similar results were found for 28-day mortality between patients with COVID-19 (35/152, 23%) and sCOVID (32/118, 27%) (P = 0.4). For the combined cohort, 28-day mortality was associated with initial oxygen saturation (P < 0.001), delirium (P < 0.001), hospital transfer for acuity (P = 0.02; but not public health/facility reasons), CFS (P = 0.04), prior ischaemic heart disease (P = 0.01) and dementia (P = 0.02). For patients with COVID-19, 28-day mortality was associated with initial oxygen saturation (P = 0.02), delirium (P < 0.001) and hospital transfer for acuity (P = 0.01), but not public health/facility reasons. CONCLUSION: Unvaccinated aged care residents meeting COVID-19 testing criteria seen by InReach during a pandemic experience high mortality rates, including with negative swab result. Residents remaining within-facility (with InReach) experienced similar adjusted mortality odds to residents transferred to hospital for public health/facility-based reasons, and lower than those transferred for clinical acuity.

Hospital treatment in residential care facilities is a viable alternative to hospital admission for selected patients.

AIM: To determine if hospital treatment in residential care facilities, led by a geriatric team, might be a viable alternative to inpatient admission for selected patients. METHODS: Case series with a new intervention were compared with historical controls receiving the conventional treatment. Treatment in residential care facilities (TRC) by the Residential Care Intervention Program in The Elderly (RECIPE) service was compared against the conventional treatment group, aged care unit (ACU) inpatients. RESULTS: A total of 95 patients in TRC and 167 patients in ACU were included. The mean Charlson Comorbidity Index score was 7 in both groups and demographics were similar, except more patients in the TRC group had dementia. Palliative care support was provided to 35.8% in the TRC group, compared with 7.8% in ACU, P < 0.001. Six-month mortality rates were similar at 30% for both groups. Rehospitalization rates at 6 months were similar at 41% for both groups. Length of care was significantly shorter for TRC (mean 2 days) compared with ACU (mean 11 days), P < 0.001. CONCLUSIONS: Hospital treatment in residential care is viable for most patients, including those with dementia and those who need palliative care support. This model of care offers a valuable geriatric service to residents who would prefer to avoid hospital transfers, with no difference in mortality or rehospitalization rates for those treated in residential care, but a significant reduction in length of care.
