This study was designed to answer the following research questions: "Are those at risk for coronary heart disease being screened for high blood cholesterol?" and "Are those with high blood cholesterol being treated according to the national guidelines?" The importance of early detection and treatment of high blood cholesterol is vital for preventive health care. A chart review of patient records was conducted to determine the behavior of the family practice residents. From the analysis of data it was determined that the residents screened their patients 83.0% of the time and when compared with national guidelines, treated those patients identified with high blood cholesterol 52.8% of the time. Third year residents screened their patients more (88.7%) for blood cholesterol than first (82.1%) or second (74.7%) year residents. Male residents screened a higher percent of their patients (84.8%) than female residents (75.0%). / Department of Physiology and Health Science
