Review of Literature
Gallagher, R., & McKinley, S. (2009). Anxiety, Depression and Perceived Control in Patients having Coronary Artery Bypass Grafts. Journal of Advanced Nursing, 65 (11), 2386–2396.
This article aims at finding out the course of anxiety, depression, and control of perceptions and the influence the control of perceptions has on patients undergoing bypass grafts of the coronary artery before, after surgery at the hospital, and 2 weeks after being discharged. A descriptive design that is prospective in nature was used for the study using a convenient sample of patients with the condition requiring surgery (n = 155). The Hospital’s Anxiety and Depression Scale and Control Attitudes Scale were used to measure anxiety and depression and perceptions of control over the illness respectively before and after surgery (during hospital stay) and 2 weeks after discharge.
The limitations were the use of a convenience sample and loss of participants for subsequent interviews. Moreover, designs involving anxiety, depression and control concurrently do not imply casualty due the likelihood hood of bidirectional effects. The patients at each point had low anxiety levels with borderline or clinically significant levels before surgery (38/-E7%) and after discharge (38/-E6%). Depression was relatively low, but increased overtime (F = 25/E-51, P < 0/-E001). Individuals having strong control perceptions had less anxiety or depression and those exhibiting anxieties before surgery exhibited the same after surgery. This assessment is necessary inorder to identify the patients at risk and promote control of perceptions.

The article is for a study that aims at determining whether a nurse-led, shared care for patients with CABG on a waiting reduces the risk factors for Coronary Artery Disease (CAD), depression, and anxiety. The study utilized a random, unblinded controlled trial that had a follow-up 1 week before surgery. The analysis used 121 (81%) patients that were on an elective CABG waiting list with 76% of these being male and the population having a mean age of 62 years.
The results revealed that nurse-led care reduced anxiety and depression (P < 0.01 for both). The study had one major limitation where observers of key outcome measures had the knowledge of the study group assignments and were involved in intervention. However, the results suggest intervention by a nurse liaison is effective to reduce risk factors in high-risk patients.
