Characteristics, symptom management and outcomes in Covid-19 patients referred to palliative care in a tertiary hospital: A retrospective observational study

INTRODUCTIONCoronavirus disease 2019 (COVID-19) variants pose unique challenges with inevitable premature death when cases of severe disease exponentially rise in a healthcare system. It is imperative that palliative care is provided with a proactive approach to symptom recognition, assessment, management and treatment escalation to ensure comfort throughout the course of this illness. OBJECTIVESTo evaluate the characteristics, symptom burden, palliative care management and outcomes of COVID-19 patients referred to a palliative care unit (PCU) in a single tertiary hospital. Clinical outcomes specifically observed the management of agitation in these patients based on their Richmond Agitation and Sedation Scale (RASS) scores. METHODSA retrospective observational study was conducted in a tertiary hospital by reviewing electronic medical records and extracting data from 1st June 2021to 31st July 2021 of all COVID-19 patients referred to the PCU. RESULTSA cohort of 154 (75 males, 79 females) COVID-19 patients was referred to the PCU with a mean age of 67 (20- 95) years. The median number of days of COVID-19 illness before referral was 7(4-11), with 79.3% of patients being in categories 4 and 5. The median duration of the PCU involvement was 4(1-24) days; 74% of families were engaged in virtual platform communication. The most prevalent symptoms were dyspnoea (73.4%) and agitation (41.6%). Common medications used were opioids, antipsychotics and benzodiazepines. Among agitated patients, none had RASS scores above +2 in the last encounter. Palliative care doctors in the team reported complete effectiveness in patient's symptom control in 74% of patients. CONCLUSIONSA hallmark of severe COVID-19 is rapid deterioration, which calls for proactive assessment and urgent palliation. Breathlessness and agitation are priority symptoms to address. Among agitated patients, benzodiazepines and antipsychotics are highly effective in addressing agitation and reducing RASS scores. Communication with families using virtual platforms is effective in providing a supportive presence and closure when face-to-face communication is not possible.
