Overview

Background Patient centeredness is an integral part of the quality of care. Patient-reported experience measures (PREMs) are assumed to be an appropriate tool to assess patient-centredness. An evaluation of German-speaking PREMs is lacking. Objective To perform a systematic review and qualitative analysis of psychometric measurement qualities of German-language PREMs using for the first time a comprehensive framework of patient centredness. Methods A systematic literature search was performed in Medline, PsycInfo, CINHAL, Embase, Cochrane database (last search 9th November 2021) for studies describing generic, surgery- or cancer care-specific PREMs. All questionnaires that were developed in or translated into German were included. The content of the included PREMs was evaluated using a comprehensive framework of patient centredness covering 16 domains. Baseline data of all PREM studies were extracted by two independent reviewers. Psychometric measurement qualities of the PREMs were assessed using current COSMIN guidelines. Results After removal of duplicates 3,457 abstracts were screened, of which 3,345 were excluded. The remaining 112 articles contained 51 PREMs, of which 12 were either developed in (4 PREMs) or translated into German (8 PREMs). Eight PREMs were generic (NORPEQ, PPE-15, PEACS, HCAHPS, QPPS, DUQUE, PEQ-G, Schoenfelder et al.), 4 cancer care-specific (EORTC IN-PATSAT32, PSCC-G, Danish National Cancer Questionnaire, SCCC) and none was surgery-specific. None of the PREMs covered all domains of patient-centeredness. Overall rating of structural validity was adequate only for PEACS and HCAHPS. High ratings for internal consistency were given for NORPEQ, Schoenfelder et al., PSCC-G and the SCCC. Cross-cultural validity for translated questionnaires was adequate only for the PSCC-G, while reliability was adequately assessed only for the EORTC IN-PATSAT32. Due to a lack of measurement gold standard and minimal important change, criterion validity and measurement invariance could not be assessed for any of the PREMs. Conclusion This is the first systematic review using a comprehensive framework of patient centredness and shows that none of the included PREMs, even those translated from other languages into German, cover all aspects of patient centredness. Furthermore, all included PREMS show deficits in the results or evaluation of psychometric measurement properties. Nonetheless, based on the results, the EORTC IN-PATSAT32 and PSCC-G can be recommended for use in cancer patients in the German-language region, while the German versions of the HCAHPS, NORPEQ, PPE-15 and PEACS can be recommended as generic PREMs. Trial Registration Registration.
