The purpose of this study is to determine whether a brief counseling intervention initiated in the chest pain observation unit has a significant impact upon the health attitudes (readiness to change) and cardiovascular risk-related behaviors (diet, exercise, and smoking) of emergency department patients.

Primary Outcome Measures:
  • Stage of change for cardiovascular risk-related behaviors (diet, exercise, and smoking) [ Time Frame: 2- and 6-months ]
  • Self-reported cardiovascular health behaviors (diet, physical activity, and smoking cessation) [ Time Frame: 2- and 6-months ]

Estimated Enrollment: 240
Study Start Date: September 2007
Estimated Study Completion Date: September 2009
Estimated Primary Completion Date: September 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 2 Behavioral: Minimal counseling
Patients assigned to minimal intervention will receive an AHA brochure ("Controlling your risk factors") with general information on management of cardiovascular risk factors. These patients will be mailed a personalized cardiovascular risk assessment report (based on baseline questionnaire and laboratory data) at the end of 6-month follow-up.
Experimental: 1 Behavioral: Enhanced counseling
The health educator will generate a computerized report for the patient that outlines his/her cardiovascular risk factors, Framingham risk score, the goal for each risk factor based on national guidelines, and recommended actions for achieving each goal. Based on the 5A's framework for behavior change, counseling for specific risk-related behaviors (diet, physical activity, and smoking) will be provided by a cardiovascular rehabilitation health educator in the emergency department and during telephone follow-up (2 sessions over 6 weeks). A full report will also be sent to the patient's primary care physician (if any) at the conclusion of counseling.

Detailed Description:
Increasingly, emergency department patients for whom a non-ischemic etiology of ACS symptoms cannot be identified undergo further evaluation to rule out myocardial ischemia and appraisal of cardiovascular risk factors (CRFs) in chest pain observation units (CPOUs). CPOU admission may represent a "teachable moment," but there has been little research on the effectiveness of brief, practical interventions for cardiovascular risk reduction in this population, despite the fact that the vast majority of these patients have at least one modifiable CRF and many do not receive regular primary care follow-up. The purpose of this study is to determine whether a brief counseling intervention initiated in the CPOU has a significant impact upon health attitudes (readiness to change) and cardiovascular risk-related behaviors (diet, exercise, and smoking). Based on the Health Belief Model (HBM), the intervention is designed to provide patients with tailored information on their cardiovascular risk, to negotiate goals for change, and to build problem-solving skills. All participants who are admitted to the CPOU for evaluation of ACS symptoms will be randomized to brief intervention (face-to-face counseling in the CPOU, coupled with telephone counseling at 4 weeks) or to minimal intervention (booklet with general information on CRFs) after a negative initial troponin measurement. We will conduct a baseline survey and follow-up telephone interviews at 2- and 6-month to assess stage of change and CRF-related behaviors. Both adjusted and unadjusted multivariable analyses will be performed to determine the intervention effect (using an intention-to-treat approach). We will also use mediation analysis to evaluate the extent to which the intervention is mediated by HBM constructs (e.g., perceived susceptibility to cardiovascular adverse events, perceived benefit of risk reduction, perceived barriers, self-efficacy). The proposed trial will evaluate the feasibility and effectiveness of delivering brief interventions for cardiovascular risk reduction in the CPOU setting, will provide insight into mechanisms of behavior change in these patients, and will guide the development of future case management interventions.
