A narrative literature review of the evidence regarding the economic impact of avoidable hospitalizations amongst palliative care patients in the UK

Background: The need to more fully understand the economics of palliative care provision is widely acknowledged; however, the evidence base regarding the extent of potentially avoidable admissions in the last year of life, and the link between reducing/redistributing overall costs of end-of-life care has not been previously evaluated. Aim: A narrative review of the evidence relating to the potential economic impact of reducing avoidable admissions among palliative care patients in the UK. Methods: Ten electronic bases were searched in 2010 using key terms to identify UK literature relating to the economic consequence of avoidable hospital admissions among palliative care patients. Results: Five studies met the inclusion criteria. Two were randomized controlled trials comparing the addition of new services to support patients in the community at the end of life with the existing standard service provided; one was a descriptive analysis of the change in usage and costs of health care services following the introduction of two community-based services; two were retrospective analyses of patient records for patient who had died in hospital to estimate the proportion of final admissions that could be classified as avoidable. Conclusions: The evidence base from the UK relating to the economic impact of avoidable admissions in palliative care is limited. Although two recent retrospective studies suggest that there are currently high levels of avoidable admissions, the feasibility of avoiding such admissions and the full economic consequences of such changes have not been clearly demonstrated. Further evidence is needed to provide a more robust estimate of the extent to which the additional costs of providing high-quality community support are offset by reduced inpatient usage by palliative care patients. Prospective studies are needed which seek to demonstrate the scale of admissions which can actually be avoided in clinical practice, when issues such as capacity constraints come into play.
