for relevance and quality assured these by means of the COSMIN-checklist. We performed a best evidence synthesis to summarise the measurement properties of each included PROM.Results: We screened 1948 references for relevance, and included 15 studies evaluating the measurement properties of four different PROMs: CDS, DMQ, SRI and a respiratory symptom checklist. None of the included instruments were validated directly for use in a palliative setting, but they generally showed promising measurement properties in other relevant settings. We still lack data on important measurement properties for all the available instruments, and currently, only SRI seems to be available in a Norwegian validated version. Further research is therefore needed to translate and validate the PROMs for use in palliative care in Norway.
