BackgroundAccess to palliative care services is variable, and many inpatients do not receive palliative care. An overview of potential barriers could facilitate the development of strategies to overcome factors that impede access for patients with palliative care needs.AimTo review the current evidence on barriers that impair, delay, or prohibit access to palliative care for adult hospital inpatients.DesignA mixed methods systematic review was conducted using an integrated convergent approach and thematic synthesis (PROSPERO ID: CRD42021279477).Data SourcesThe Cochrane Library, MEDLINE, CINAHL, and PsycINFO were searched from 10/2003 to 12/2020. Studies with evidence of barriers for inpatients to access existing palliative care services were eligible and reviewed.ResultsAfter an initial screening of 3,359 records and 555 full-texts, 79 studies were included. Thematic synthesis yielded 149 access-related phenomena in 6 main categories: 1) Sociodemographic characteristics, 2) Health-related characteristics, 3) Individual beliefs and attitudes, 4) Interindividual cooperation and support, 5) Availability and allocation of resources, and 6) Emotional and prognostic challenges. While evidence was inconclusive for most socio-demographic factors, the following barriers emerged: having a noncancer condition or a low symptom burden, the focus on cure in hospitals, nonacceptance of terminal prognosis, negative perceptions of palliative care, misleading communication and conflicting care preferences, lack of resources, poor coordination, insufficient expertise, and clinicians' emotional discomfort and difficult prognostication.ConclusionHospital inpatients face multiple barriers to accessing palliative care. Strategies to address these barriers need to take into account their multidimensionality and long-standing persistence.Copyright © 2023 The Authors. Published by Elsevier Inc. All rights reserved.
