Background: In cost-effectiveness analyses in healthcare, Quality-Adjusted Life Years are often used as outcome measure of effectiveness. However, there is an ongoing debate concerning the appropriateness of its use for decision-making in palliative care. Aim: To systematically map pros and cons of using the Quality-Adjusted Life Year to inform decisions on resource allocation among palliative care interventions, as brought forward in the debate, and to discuss the Quality-Adjusted Life Year’s value for palliative care. Design: The integrative review method of Whittemore and Knafl was followed. Theoretical arguments and empirical findings were mapped. Data sources: A literature search was conducted in PubMed, EMBASE, and CINAHL, in which MeSH (Medical Subject Headings) terms were Palliative Care, Cost-Benefit Analysis, Quality of Life, and Quality-Adjusted Life Years. Findings: Three themes regarding the pros and cons were identified: (1) restrictions in life years gained, (2) conceptualization of quality of life and its measurement, including suggestions to adapt this, and (3) valuation and additivity of time, referring to changing valuation of time. The debate is recognized in empirical studies, but alternatives not yet applied. Conclusion: The Quality-Adjusted Life Year might be more valuable for palliative care if specific issues are taken into account. Despite restrictions in life years gained, Quality-Adjusted Life Years can be achieved in palliative care. However, in measuring quality of life, we recommend to—in addition to the EQ-5D— make use of quality of life or capability instruments specifically for palliative care. Also, we suggest exploring the possibility of integrating valuation of time in a non-linear way in the Quality-Adjusted Life Year.
