Abstract Details

2003, Doctor of Philosophy, Ohio State University, Nursing.
Lower extremity peripheral arterial disease (PAD), which results from peripheral atherosclerosis, affects up to 10 million people in the United States alone. Claudication, defined as a walking-induced pain in one or both legs relieved by rest, is the primary symptom of lower extremity PAD, and causes significant disability in many patients. The three main treatment options for PAD are lifestyle management, medical therapy, and surgical intervention. Vascular nurses play a critical role in the collaborative care of PAD patients by offering counseling to change unhealthy behaviors, yet patients experience problems in actually overcoming sedentary lifestyle and nicotine addiction. Therefore, the purpose of the current study was to identify factors that promote the adoption and maintenance of exercise and smoking cessation behaviors with PAD patients. A pretest-posttest control group design with a 12-week exercise and smoking cessation intervention was implemented, with outcome measures assessed at baseline, 3 and 6 months post enrollment. The model used for developing this intervention study was the Transtheoretical Model of Behavior Change (TTM). Constructs from the TTM along with principles of nicotine addiction and exercise determinants were used to develop stage-specific interventions. In addition, functional status was measured. The intervention group did have significant increases (p < .05) from baseline in claudication pain time (CPT) at 3 and 6 months, and in maximal walking time (MWT) at 3-months only. Baseline exercise self-efficacy significantly correlated with 3-month exercise stage of change for the usual care group. In addition, there was a significant difference between groups (p < .05) for exercise stage of change at 3-months, but not at 6 months. There were no significant changes in either smoking decisional balance or smoking stage of change over time by group. As a result, all smokers data (n = 15) were collapsed and analyzed, with differences and trends discussed, and themes identified. Results from this study support the premise that a nurse-managed, theory based exercise adoption intervention is effective in helping claudicants adopt a routine exercise program. In addition, when combined with a critical health event, this intervention may contribute to claudicants’ successful smoking cessation.
