Knowledge, attitude, and practice of patients receiving maintenance hemodialysis regarding hemodialysis and its complications: a single-center, cross-sectional study in Nanjing

Background Good knowledge of and attitudes toward hemodialysis and its complications might be expected to promote good practices and improve adherence. This study investigated, the knowledge, attitude, and practice of patients receiving hemodialysis regarding hemodialysis and its complications.Methods This cross-sectional study enrolled patients with uremia who were receiving hemodialysis at the Second Affiliated Hospital of Nanjing Medical University (China) between January 9, 2023, and January 16, 2023. A questionnaire was designed that included the following dimensions: demographic/clinical information, knowledge, attitude, and practice. Correlations between knowledge, attitude, and practice scores were evaluated by Pearson correlation analysis.Results The analysis included 493 patients (305 males, 61.87%). The average knowledge, attitude, and practice score was 19.33 +/- 7.07 (possible range, 0-31), 28.77 +/- 3.58 (possible range, 8-40), and 43.57 +/- 6.53 (possible range, 11-55) points, respectively. A higher knowledge score was associated with younger age (P < 0.001), a higher education level (P < 0.001), and not living alone (P < 0.001), while a higher practice score was associated with a shorter history of hemodialysis (P < 0.001). There were positive correlations between the knowledge and practice scores (r = 0.220, P < 0.001) and between the attitude and practice scores (r = 0.453, P < 0.001), although the knowledge and attitude scores were not significantly correlated.Conclusions The results provide important insights into the knowledge, attitudes, and practices of patients with uremia in Nanjing (China) regarding hemodialysis and its complications. These findings may facilitate education programs to improve self-care practices in patients receiving maintenance hemodialysis in Nanjing (China).
