Challenges with end-of-life care in COVID patients requiring non-invasive respiratory support

ABSTRACT

IntroductionThe COVID-19 pandemic has seen an unprecedented number of adults receiving non-invasive respiratory support (NIRS) with such patients having a high mortality rate.MethodsAs part of better elucidating the challenges of end of life care delivery in the COVID era, we conducted an audit of our respiratory HDU ward at Whipps Cross Hospital focusing on a 19-week period between 17/09/2020–30/01/2021 and on patients who did not survive their admission. We excluded patients that were transferred to ITU.ResultsOf a total of 309 patients receiving NIRS on our ward, 84 died during that time at a mean age of 77 (95% CI 67–87) and median of 79 years. 63 patients received CPAP, 67 received HFNT and 42 were first started on HFNT and converted to CPAP. The average length of stay was 10 days (4–16). The mean day of symptoms on presentation to hospital was 11.5 days (1.7–21.3). Average duration of symptoms prior to admission to our ward was 19.7 (9.1–30.3) days.One death was unexpected and followed a cardiac arrest. The most common indicator for a patient approaching end-of-life was hypoxia on NIRS, which was documented in 36 (43%) patients, followed by terminal agitation in 27 (32%) patients. The average time between recognising end-of-life and death was 1.4 days with a median of 2 days. 72 (86%) patients were weaned off NIRS and those who continued did so due to a medical or patient decision. Despite the vast majority (82% of patients) being on syringe drivers with an opiate and benzodiazepine most patients had persistent terminal symptoms 51 (74%) had agitation and 38 (55%) were persistently breathlessness. Interestingly, no patient opted to rest in the prone position.DiscussionThis data primarily suggests the challenging nature of managing end-of-life care for COVID patients deteriorating on NIRS due to the high symptom load and the short time there is to achieve comfort for these individuals. Clinicians need to conduct frequent comfort reviews for such patients, consider subcutaneous infusions, as well as potentially an increase in medication doses, in conjunction with specialist palliative care input, in order to achieve comfort.
