ED and quality of life in CABG patients: an intervention study using PRECEDE-PROCEED educational program.

Some reports have examined ED, an important indicator of quality of life (QoL), in cardiac patients. However, the results of these studies have been contradictory. Although some studies report of improvement of ED following coronary artery bypass graft (CABG), others show either no improvement or worsening of the condition. Given such controversy, this study attempted to examine the status of ED following an educational intervention program called PRECEDE-PROCEED model in CABG patients (the PRECEDE acronym stands for predisposing, reinforcing, enabling constructs in educational/environmental diagnosis and evaluation and PROCEED stands for policy, regulatory and organizational constructs in educational and environmental development). This model is a planning model and offers a framework that enables us to recognize useful intervention strategies in achieving desired outcomes. Specifically, it works on two premises. First, it posits that the purpose of a health program is to improve the QoL for individuals. Second, it works on the principle that a diagnosis should begin with the preferred end result and work backward to assess what must be done to bring about that result. As such, the results of our study showed that the implementation of the intervention program following surgery not only significantly decreased ED but enhanced the QoL. Thus, utilization of educational intervention program after CABG operations is recommended.
