Functional status changes in patients receiving palliative care consult during COVID-19 pandemic.

CONTEXT: Hospitalized patients with functional impairment have higher symptom burden and mortality. Little is known about how increased patient volume and acuity during the coronavirus disease 2019 (COVID-19) pandemic affected access to palliative care among patients with functional impairment.

OBJECTIVES: To examine changes in functional status and hospital outcomes among patients receiving inpatient palliative care consultation before, during and after the COVID-19 pandemic.

METHODS: We conducted a retrospective, multi-site cohort study of all adult patients (≥ 18 years) admitted to four hospitals in New York City, USA, who received inpatient palliative care consultation between March 1, 2019 and February 28, 2022 with documented functional status at the time of consultation measured by Karnofsky Performance Status scale.

RESULTS: Among 13,180 eligible patients identified, patients' functional status at the time of consultation decreased as palliative care consult volume increased with the onset of the pandemic. Compared to pre-pandemic, there was a statistically significant trend of lower functional status (p<0.001) and higher in-hospital mortality (p<0.001) among patients with non-cancer and non-COVID-19 diagnoses two years after the pandemic. In contrast, patients with cancer had a statistically significant trend of higher functional status (p<0.001) and no significant changes in in-hospital mortality over time.

CONCLUSION: As the healthcare system was stressed with high demand and limited resources, palliative care consultation prioritized highest acuity patients by shifting towards those with lower functional status and higher in-hospital mortality. This shift disproportionately affected non-cancer patients. Innovative approaches to ensure upstream palliative care consultation during increased resource constraints are needed.
