Aim: The aim of this study was to investigate the effect of care needs on quality of life and chronic disease care in patients with type-2 diabetes. Methods: A cross-sectional and descriptive study. One hundred forty-five patients with type-2 diabetes who were followed-up between January 2016 and January 2017 in the university hospital were included in the study. The "Patient Presentation and Care Management Evaluation Form", "Quality of Life Assessment Scale (EQ-5D-5L)" and "Chronic Illness Care Assessment Scale-Patient Form (PACIC)" were used for the collection of data. One-way ANOVA test, Tukey HDS test, independent two-sample t-test, Kruskal Wallis test, Mann Whitney U test and Pearson correlation analysis were used for the evaluation of data. Results: In this study, the average total PACIC score of patients with type-2 diabetes was found to be satisfactory (3.78±0.79). However, the EQ-5D-5L average score was found to be close to perfect (0.84±0.17). A positive correlation was found between EQ-5D-5L scores and PACIC decision support and goal setting/guidance sub-scale scores, and a negative correlation was found between positive EQ-5D-5L score and body mass index and HbA1c values. A significant correlation was also found between current diabetes treatment compliance and the EQ-5D-5L general health score and PACIC total score. The PACIC decision support and goal setting/guidance sub-scales were found to be significantly different based on the diabetes education status of patients with type-2 diabetes. Conclusions: Planning health education and counseling programs for general care adjustment are recommended for chronic disease management of diabetes.
