Abstract
Objective
This randomized controlled trial evaluated the effectiveness of a telephone-delivered, spouse-assisted lifestyle intervention to reduce patient LDL-C.Method
From 2007 to 2010, 255 outpatients with LDL-C>76 mg/dL and their spouses from the Durham Veterans Affairs Medical Center were randomized to intervention or usual care. The intervention comprised nine monthly goal-setting telephone calls to patients and support planning calls to spouses. Outcomes were assessed at 11 months.Results
Patients were 95% male and 65% White. LDL-C did not differ between groups (mean difference = 2.3 mg/dL, 95% CI = -3.6, 8.3, p = 0.44), nor did the odds of meeting goal LDL-C (OR = 0.95, 95% CI = 0.6, 1.7; p = 0.87). Intakes of calories (p = 0.03), total fat (p = 0.02), and saturated fat (p = 0.02) were lower for the intervention group. Cholesterol and fiber intake did not differ between groups (p = 0.11 and 0.26, respectively). The estimated rate of moderate intensity physical activity per week was 20% higher in the intervention group (IRR = 1.2, 95% CI = 1.0, 1.5, p = 0.06). Most participants did not experience a change in cholesterol medication usage during the study period in the intervention (71.7%) and usual care (78.9%) groups.Conclusion
This intervention might be an adjunct to usual primary care to improve adherence to lifestyle behaviors.Type

Dr. Bosworth is a health services researcher and Deputy Director of the Center of Innovation to Accelerate Discovery and Practice Transformation (ADAPT) at the Durham VA Medical Center. He is also Vice Chair of Education and Professor of Population Health Sciences. He is also a Professor of Medicine, Psychiatry, and Nursing at Duke University Medical Center and Adjunct Professor in Health Policy and Administration at the School of Public Health at the University of North Carolina at Chapel Hill. His research interests comprise three overarching areas of research: 1) clinical research that provides knowledge for improving patients’ treatment adherence and self-management in chronic care; 2) translation research to improve access to quality of care; and 3) eliminate health care disparities.
Dr. Bosworth is the recipient of an American Heart Association established investigator award, the 2013 VA Undersecretary Award for Outstanding Achievement in Health Services Research (The annual award is the highest honor for VA health services researchers), and a VA Senior Career Scientist Award. In terms of self-management, Dr. Bosworth has expertise developing interventions to improve health behaviors related to hypertension, coronary artery disease, and depression, and has been developing and implementing tailored patient interventions to reduce the burden of other chronic diseases. These trials focus on motivating individuals to initiate health behaviors and sustaining them long term and use members of the healthcare team, particularly pharmacists and nurses. He has been the Principal Investigator of over 30 trials resulting in over 400 peer reviewed publications and four books. This work has been or is being implemented in multiple arenas including Medicaid of North Carolina, private payers, The United Kingdom National Health System Direct, Kaiser Health care system, and the Veterans Affairs.
