Referrals to Palliative Care Services for Hospitalised COVID-19 Patients: A Systematic Literature Review.

Background: The increase in the incidence of the coronavirus disease 2019 (COVID-19) led to more hospital admissions and deaths, and coincided with an increased need for palliative care. The new circumstances required palliative care services to be flexible and to develop response strategies.

Aim: To synthesise studies including COVID-19 patients to gain insight into how many patients were referred to hospital-based palliative care services, the characteristics and palliative care needs of these patients and the reasons for referral.

Design: A systematic literature search was conducted in January 2022 using the PubMed, Embase, CINAHL, and PsycInfo databases.

Results: Twenty-seven studies were identified. The results show that in 16% of all COVID-19 inpatients and 55% of all deceased COVID-19 inpatients were referred to a palliative care service. The median time from hospital admission to referral was 4 days and from referral to death was 2 days. COVID-19 inpatients were frequently referred for end-of-life care management (52%), had ≥1 comorbidities (84%), and suffered from shortness of breath/dyspnea (45%).

Conclusions: The care provided was generally acute, with a high proportion of end-of-life care referrals and a short time period from hospital admission to referral and from referral to death. This highlights the importance of early integration of palliative care into emergency department (ED) care of critically ill patients.
