Effects of intervention on compliance to referral and lifestyle recommendations given at cholesterol screening programs.

To enhance compliance to physician referral as well as dietary and other lifestyle recommendations given at blood cholesterol (BC) screening programs, we randomized Pawtucket Heart Health Program SCORE (screening, counseling, referral event) participants with elevated BC levels into one of four groups: usual care group; a participant intervention group (mailed reminder letter and refrigerator magnet); a physician intervention group (mailed packet to participant's physician including letter, National Cholesterol Education Program [NCEP] guidelines, and preaddressed postcard to mail to patient); and a group that received both interventions. Beginning four months after the screening, we surveyed study subjects by phone. The participant intervention increased recall of physician referral and dietary recommendations; however, neither intervention successfully improved compliance to referral or dietary and lifestyle recommendations. Overall, 58%, 67% and 34% of subjects reported complying to physician referral, dietary recommendations, and lifestyle recommendations, respectively. Referral compliance was associated with a longer time interval between screening and survey (relative risk [RR] = 1.3, 95% confidence interval [CI[ = 1.0, 1.7), possession of medical insurance that covered physician visits (RR = 2.1, 95% CI = 0.98, 4.4), and history of hypertension (RR = 2.6, 95% CI = 1.1, 5.8). Dietary compliance was positively associated with baseline BC levels > or = 240 mg/dL (RR = 3.3, 95% CI = 1.4, 7.3) and negatively associated with increasing age; each one year increase in age corresponded to a 3% decrease in compliance (RR = 0.97, 95% CI = 0.9. 1.0).(ABSTRACT TRUNCATED AT 250 WORDS)
