What socio-economic factors determine place of death for people with life-limiting illness? A systematic review and appraisal of methodological rigour

Abstract

Background: Socio-economic factors play important roles in place of death. However, up-to-date knowledge on socio-economic determinants for place of death is warranted including analysis of collinearity between socio-economic determinants. Aim: To examine associations between socio-economic determinants (social class, deprivation level in area of residence, income, education, occupation, urbanisation) and place of death among adult patients with life-limiting illnesses. Furthermore, to describe how these factors are operationalised and examined for collinearity. Design: A systematic review was performed (PROSPERO, record: CRD42018091218) and quality was assessed using the Newcastle–Ottawa Scale. Data sources: A comprehensive search of PubMed, Embase, CINAHL, Scopus and PsycINFO was conducted for studies published from 1 January 2008 until the date of the search (23 March 2018) in English or Scandinavian languages. Results: Of the 1599 unique citations identified, 34 studies were eligible. Dying at home was to a high degree associated with better financial situation and living in rural areas. Furthermore, hospital death was associated with a high level of deprivation in the area of residence and being employed. Regarding educational level, we found mixed and inconclusive results. Conclusion: Inequalities concerning place of death were found, and attention towards socio-economic inequality concerning place of death is necessary, especially in patients with a poor financial status, patients living in deprived and metropolitan areas and patients who are employed. Furthermore, we found a low degree of assessment for collinearity and adjustment of socio-economic variables. These issues should be considered in planning of future studies of socio-economic determinants for place of death.
