Training health professionals and lay volunteers to deliver cholesterol screening and education programs.

The National Heart, Lung, and Blood Institute of the National Institutes of Health launched the National Cholesterol Education Program (NCEP) in 1985. With the goal of reducing the prevalence of elevated blood cholesterol in the United States, the NCEP aims to raise awareness and understanding in both health professionals and the general public of high blood cholesterol levels as a risk factor for coronary heart disease. Public interest in blood cholesterol measurement has created an enormous market for cholesterol screening and education programs. The importance of quality screening and educational services was recognized by the NCEP, which has urged the training of all personnel involved in public cholesterol screenings. This paper presents models for training lay volunteers and health professionals to deliver quality public screening programs for high blood cholesterol that are consistent with NCEP recommendations. Blood cholesterol screening, counseling, and referral (SCORE) programs are key intervention strategies of the Pawtucket Heart Health Program (PHHP), a cardiovascular disease prevention research program in Pawtucket, RI. This paper describes the PHHP volunteer training and certification program for cholesterol SCOREs and the demographics of screening volunteers. With the goal of improving the quality of cholesterol screening and education programs nationally, the Cholesterol Training Center (CTC) was established in 1988. Using models established by PHHP, the center developed training workshops to help health professionals initiate, update, expand, or enhance training for cholesterol screening and education programs. CTC training protocols and the characteristics of workshop participants are described, and the workshops' effects on participants' knowledge and self-sufficiency are discussed.

Performance characteristics of a blood cholesterol measuring instrument used in screening programs.

Four experiments were conducted to assess the precision and accuracy of the Boehringer Mannheim Diagnostics Reflotron, an instrument that is being adopted by many public health groups to conduct blood cholesterol screening programs. Our study is one of the first to evaluate and document the instrument's performance characteristics. Successive generations of reagent tabs supplied by the manufacturer were tested against a reference laboratory method standardized by the Centers for Disease Control. Three of the experiments also compared two or more Reflotrons to assess intermachine reliability. The Reflotron analyzer provided precise blood cholesterol measurements both in repeated tests and among instruments. The accuracy of the method varied across reagent lots, with an average negative bias of 21.05 milligrams per deciliter (mg per dl), decreasing steadily to a negative bias of 4.07 mg per dl. Reliability between and within analyzers was high. The data provide support for the use of the instrument in blood cholesterol screening efforts, yet signal the need for attention to quality control procedures, both by the manufacturer and operators, to ensure the validity and accuracy of the results.

Cross-sectional relationship between diet and physical activity in two southeastern New England communities.

The hypothesis that health promotive diets associated with higher levels of habitual physical activity confound the relationship between regular physical activity and health has not been well explored in epidemiologic studies. We evaluated self-reported physical activity, Willett Food Frequency dietary data, sociodemographic and physiologic factors cross-sectionally for 2,004 household survey participants in two southeastern New England communities. We compared the dietary habits of sedentary participants (n = 964) to those of moderately active (n = 600) and very active (n = 440) participants after adjusting for age, gender, education, smoking status, year of survey, and total calories. Our results showed that moderately active and very active participants consumed more fiber, less total fat, and less saturated fat than sedentary participants (P < .01). They also consumed more vitamins (A, C, D, E), beta carotene, and calcium, (P < .01), and ate more fruits and vegetables (P < .001) than sedentary participants. We found these relationships in both New England communities studied. This association between regular physical activity and diet suggests that the relationship of habitual physical activity and chronic disease may be confounded by diet.

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)

Changing physicians' attitudes, knowledge, and self-efficacy regarding cholesterol screening and management.

The National Cholesterol Education Program (NCEP) has identified a need to convey practical approaches for the management of high blood cholesterol (BC) to physicians. Our study was a joint effort between the Pawtucket Heart Health Program and the Brown University Department of Family Medicine to improve family medicine residents' attitudes, knowledge, self-efficacy, and practices regarding cholesterol screening and management. Thirty-six resident physicians received a BC screening and management training program. This program included training in BC screening using the fingerstick method and a desktop analyzer, diet assessment and counseling, and a management protocol for evaluation and treatment of high BC based on NCEP guidelines. The training program also included evaluation of residents' BC screening activity, incentives, chart audits, and biweekly articles in the departmental newsletter. We administered a survey to residents before and one year after the training program began to assess self-reported knowledge, attitudes, self-efficacy, and practices for BC management. Survey results indicated that the residents significantly improved their reported knowledge and attitudes about BC management. In addition, they significantly increased their reported self-efficacy and practices in dietary counseling and patient education. Residents also indicated that the training program was worthwhile, necessary, and practical and that many would use the materials and protocols in their future practices.
