Abstract 1250: The Know & Go! Program Improves Knowledge of Symptom Management in Patients at High Risk for Acute Coronary Syndromes
Background/Significance: Intervening to improve cognitive and behavioral responses to symptoms of acute coronary syndromes is important given persistently long patient delay in seeking emergency treatment. However, there is limited research testing interventions initiated prior to hospital discharge for heart disease.
Purpose: To determine if patients hospitalized for elective angioplasty could learn symptom management strategies prior to and after discharge and to evaluate patient acceptability of the intervention.
Methods: This randomized controlled trial enrolled 32 women and 32 men, 18–24 hours following angioplasty. Participants were randomly assigned to groups using the sequentially numbered opaque sealed envelope method. Both groups completed a symptom pre-test on a touch screen computer located in a private office on the unit. The experimental group then viewed the self-directed Know & Go! symptom management slide presentation, developed for the study, on the computer. They returned to view the program and complete post-tests 2 months and 4 months after discharge. Patients in the control group completed post-tests over the phone. A satisfaction survey was mailed to patients in the experimental group at the completion of the study. Repeated measures analysis of variance and independent t-test were used to compare groups on pre and post test scores.
Results: Data from 25 women and 27 men who completed all three time points were included in the analysis. There were no significant differences between groups on characteristics of age (M=63.3 years), education, marital status, race, income, history of angina, or history of myocardial infarction. The experimental group scored significantly higher on post tests (F=16.58, p<.001); evident at both 2 months (t=3.36; p<.001) and 4 months (t=.4.40; p<.001) following discharge. Patients who returned a satisfaction questionnaire (75%) were highly satisfied with the program and computer technology (range 0–12, M=9.85±1.91).
Conclusions: The Know & Go! intervention was safe, efficacious, cost-effective, and acceptable to patients in pilot testing. Results support refinement of a tailored symptom management intervention for the general public and patients at risk for acute coronary syndromes.
