AIM: The aim of this research is to identify the main approaches and domains of palliative care quality assessment through three questionnaires used for this purpose. DESIGN: Systematic review. METHODS: The proposed analysis process consists of three stages from 2000 to 2020: (i) massive literature search, (ii) text mining and (iii) systematic reviews carried out on the QLQ C30, Zarit Burden Interview and FAMCARE questionnaires. The Preferred Reporting Items for Systematic Reviews (PRISMA-P) have guided our research. RESULTS: Sixteen papers were included in our study. The main findings have been summarised using a descriptive narrative synthesis approach. Systematic reviews evidenced that such tools present variable factor structures or latent domains. The results obtained are generally representative of the evidence supporting the factor structure of the QLQ-C30 in the general cancer population. The factor structure of the Zarit Burden Interview remains ambiguous, although the idea of a unifactorial structure predominates. In the case of FAMCARE, most of the factor structures differ from the initial proposal of Kristjanson. The categorisation of the main subjective assessment approaches could be useful for the construction of a coherent system of indicators to be used in nursing practice. For its part, the variability in the latent dimensionality of the questionnaires analysed could be due to: (i) the characteristics of the sample, (ii) the population studied, (iii) cross-cultural variability, (iv) the design of the questionnaire and (v) the analysis techniques employed.
