Palliative care is constantly increasing around the world. The knowledge and skills of future physicians in this area are crucial. This study evaluates the psychometric properties of knowledge and skills questionnaires used in palliative care, validated by physicians or medical students based on the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology. A systematic review was carried out in Cosmin Databases, Cochrane Library, PsycINFO, SciELO, Cinahl, and Medline up to September 2020 (updated June 2021), based on the COSMIN methodology and PRISMA recommendations. The psychometric properties of each included questionnaire were identified. Methodological quality, quality of results, and quality of evidence were evaluated. The search strategy yielded 12 questionnaires assessing the knowledge and skills of physicians or medical students. The Palliative Care Knowledge Questionnaire for PEACE (PEACE-Q) and Palliative Care Knowledge Test (PCKT) were the instruments with the highest scores for methodological quality, quality of results, and quality of evidence-based on the COSMIN methodology. PEACE-Q and PCKT should be the preferred choice to assess palliative care knowledge and skills in physicians. In-depth studies following COSMIN validation criteria are recommended to improve the psychometric properties and cross-cultural validation of the questionnaires.
