Why do adults with palliative care needs present to the emergency department? A narrative review of the literature

Abstract

Background: Given the increasing emphasis on community-based provision of palliative care and the view that good dying should occur at home, it is unsurprising that policy in many countries has started focusing on preventing hospital admissions at the end of life. However, little attention has been paid to the role of the emergency department (ED) in this regard, despite the fact that a high proportion of hospital admissions among patients with palliative care needs originate in the ED. This paper presents the next logical step in improving understanding of ED use within a palliative care context; as to determine what constitutes an avoidable ED presentation initially requires recognition of the reasons that such patients are presenting.Methods: A systematic, narrative approach was used to appraise the relevant studies. From August to December 2014, electronic databases, gray literature and guidelines were searched, using MeSH headings and keywords. As it was anticipated that reasons for presentation would be differently described, all papers addressing presentations to the ED among patients with palliative care needs were identified; information regarding reasons for presentation were then examined.Results: Twelve papers ultimately met the inclusion criteria and were accessible. The ‘reason’ for a patient's presentation was largely defined as their ‘presenting complaint’ or ‘underlying diagnosis.’ There was consistency in the studies in this respect; the majority found that people with lung cancer and those experiencing distressing respiratory symptoms were most likely the present to the ED. Subsequently, pain and gastrointestinal symptoms such as nausea and vomiting were uniformly found to be most common. The three prospective studies gathered information about reason for presentation from the patient perspective using structured questionnaires, but no study collected qualitative data from patients and families.Discussion: This systematic narrative review is the first to explore reasons for ED presentation among patients with palliative care needs. However, the data does not facilitate a detailed discussion about the difficulties that this population of patients face, and whether they may be best managed in an acute or community setting. A deep understanding of the perspectives of patients is urgently needed, so as to both understand their reasons for presentation and implement relevant patient-directed changes in service provision.
