OBJECTIVES: To assess the use of quality of life questionnaires in polish cardiac patients, as well as research methods used by polish authors in terms of international quality of life research guidelines.   METHODS: Systematic literature review was performed in order to collect publications assessing quality of life in cardiac patients in Poland. Medical databases and the most important health agencies websites were searched for HRQoL assessment guidelines. Inclusion criteria: studies carried in the Republic of Poland; studies in which authors were using HRQoL questionnaires in cardiac patients. Exclusion criteria: Studies carried outside of Poland; studies estimating HRQoL among patients with vascular diseases; case reports; researches and review papers without HRQoL assessment. Based on the international guidelines, “checklist” consisting of 19 statements and questions was created as a basis for data extraction from accessed publications. RESULTS: As a result of systematic literature review and inclusion criteria application, 131 polish publications were included in this analysis. 26% of all researches were based on questionnaires designed by the authors for their own needs, of which 71% have never been validated. Results of questionnaires were calculated using official key only in 43% of publications. Among the included studies, 63% assessed HRQoL as a primary endpoint. Observational studies assessing HRQoL in polish cardiac patients without any interventions were the most common (41%). At the same time, 36% of studies were related to surgical intervention. CONCLUSIONS: Polish studies assessing HRQoL in cardiac patients often do not meet all the requirements stated in international guidelines. Promoting of the results of this work can increase the awareness of polish authors in terms of proper HRQoL measures.
