Abstract

Background: Adherence to prescribed therapeutic regimen is an important element of self-care behaviors in cardiac patients. Awareness of disease may play an important role in patient adherence. Thus, this study was conducted to examine the relationship between awareness of the disease and adherence to therapeutic regimen among cardiac patients admitted to selected hospitals in Mashhad, Iran.Methods: Using a descriptive correlational design, 340 patients with heart disease were selected using convenience sampling from five hospitals in Mashhad during December 2009 to May 2010. Data were collected using three questionnaires including demographic information, awareness of disease and treatment adherence (including medication, diet and physical activity). Validity and reliability of the questionnaires were examined by content validity and test-retest, respectively. Also, inter-rater reliability was examined for two data raters. Data were analyzed by SPSS software, using Spearman and Kruskal-Wallis tests.Results: The results showed that only 15 percent of the study subjects had a good awareness of their disease. The majority of patients followed a good medication adherence (79 %), good diet adherence (60%), and weak physical activity adherence (61%). A significant correlation was found between knowledge and adherence to therapeutic regimen (P=0.001, rp=0.32).Conclusion: This study showed that awareness of disease and adherence to physical activity was low in the majority of patients. It is recommended that studies should be conducted to explore effective educational programs and strategies to improve adherence to therapeutic regimen among cardiac patients.
