BACKGROUND
To date, there is a lack of standardization and consensus on which outcomes are central to assess the care provided to patients in the last month of life. Therefore, we aimed to conduct a systematic review to identify relevant outcomes to inform the development of a core outcome set for the best care for the dying person.
METHODS
We conducted a systematic review of outcomes reported in the scientific literature about the care for the dying person in the last month of life. We searched for peer-reviewed studies published before February 2022 in four electronic databases. To categorise the outcomes, we employed the taxonomy developed by the "Core Outcome Measures in Effectiveness Trials" collaboration.
RESULTS
Out of the 2,933 articles retrieved, 619 were included for analyses. The majority of studies (71%) were retrospective and with data extracted from chart reviews (71%) . We extracted 1,951 outcomes in total, from which, after deletion of repeated outcomes, we identified 256 unique ones. The most frequently assessed outcomes were those related to medication or therapeutic interventions and those to hospital/ healthcare use. Outcomes related to psychosocial wellbeing were rarely assessed. The closer to death, the less frequently the outcomes were studied.
CONCLUSIONS
Most outcomes were related to medical interventions or to hospital use. Only a few studies focused on other components of integrated care such as psychosocial aspects. It remains to be defined which of these outcomes are fundamental to achieve the best care for the dying.
