Background: Coronary artery disease and its associated treatment interventions such as angioplasty can lead to emotional problems, including depression, anxiety, and stress, in patients and might have adverse effects on the recovery process. This study aimed to evaluate the effect of collaborative care model on depression, anxiety, and stress in patients after coronary angioplasty.
Methods: This clinical trial was conducted on 50 patients undergoing coronary angioplasty, who were referred to intensive care unit and surgical ward of one of the hospitals of Isfahan, Iran, in 2015. Samples were selected through randomized convenience sampling and were divided into intervention and control group (n=25 for each group). Collaborative care model, consisting of four stages of motivation, preparation, engagement, and evaluation, was implemented for the intervention group through five 45-60 minute sessions and a three-month telephone follow-up. Data was collected using depression, anxiety, and stress scale (DASS-42) before and one month after the intervention from both groups. Data were analyzed using descriptive statistics, Chi-square, as well as independent and paired t-tests in SPSS, version 18.
Results: In this study, mean score of depression was significantly decreased in the intervention group after the implementation of collaborative model (from 31.6±3.7 to 6.3±5.03) (P<0.001), and mean anxiety and stress scores were reduced from 32.6±3.04 and 32.2±3.3 to 6.2±4.1 and 8.5±4.8, respectively (P<0.001). In this regard, a significant difference was observed between the intervention and control groups (P<0.001).
Conclusion: Implementation of collaborative care could be associated with lower depression, anxiety, and stress in patients after coronary angioplasty. Therefore, its application is recommended as an effective method for such patients.
