Condition(s) targeted: Obesity; Cardiovascular Risk Factors

Intervention: Stepped Care (Behavioral)

Phase: N/A

Status: Completed

Sponsored by: University of California, San Diego

Official(s) and/or principal investigator(s):
Kevin Patrick, MD, MS, Principal Investigator, Affiliation: UCSD

Summary

The researchers propose a randomized controlled trial to evaluate how well an intervention, Planned Care for Obesity & Risk Reduction (Planned CORR), supports primary care treatment of obesity in adults with at least one cardiovascular risk factor (CVRF).

Clinical Details

Official title: Planned CORR: Planned Care for Obesity and Risk Reduction

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Prevention

Primary outcome: The primary aim is to evaluate the effects at 20 months of Planned CORR on BMI when compared to enhanced usual care.

Secondary outcome:

CVRF outcomes; physiological, metabolic, behavioral, and psychosocial factors related to obesity and CVRFs; quality of life, depression, cost-effectiveness; and medical care quality, patient, provider & staff satisfaction, and process measures.

Detailed description: The researchers propose a randomized controlled trial to evaluate how well an intervention, Planned Care for Obesity & Risk Reduction (Planned CORR), supports primary care treatment of obesity in adults with at least one cardiovascular risk factor (CVRF). We will assess how well it creates initial and sustained improvements in BMI and metabolic, anthropometric and behavioral outcomes in obese adults, age 25 to 70 who have one or more of the following CVRFs: hypertension, smoking or the metabolic syndrome. Planned CORR integrates intervention components based on behavior change theory with a delivery strategy based on the Chronic Care Model (Wagner et al, 2001; also called the "Planned Care Model") and is designed to incorporate intervention principles used successfully to treat obesity. Planned CORR is intended to be compatible with a variety of primary care settings including those with minimal resources to devote to patient education and where most obese adults receive their usual medical care. Study participants will be 380 women and men, age 25-70 who meet the entry criteria of obesity (Class I & II; BMI 30-45) plus one or more CVRFs. We anticipate that approximately 40% will be Hispanic and we will recruit an equal number of women and men and have powered the study to do analyses by gender. Planned CORR is a stepped care intervention that begins with computer-assisted assessment and tailored action planning, physician or nurse practitioner counseling, and an intensive "first step" of 4 months of lifestyle modification delivered via monthly in-person sessions and phone calls and weekly web or mail (based on preference) tutorials. CVRFs are managed concurrently according to recognized evidence-based protocols. Successive 4-month steps involve more, the same, or less intensive intervention depending on clinical response. The primary aim is to evaluate the effects at 12 & 24 months of Planned CORR on BMI when compared to enhanced usual care. Secondary aims will evaluate: CVRF outcomes; physiological, metabolic, behavioral, and psychosocial factors related to obesity and CVRFs; quality of life, depression and cost-effectiveness; and medical care quality, patient, provider & staff satisfaction, process measures relevant to implementation in primary care. Post study aims are to disseminate the knowledge gained from the intervention through conferences and publications, and to disseminate Planned CORR through proven channels of health care intervention dissemination.
