Missed Opportunity in the Treatment of Hyperlipidemia in Patients with Coronary Heart Disease: The Primary Care Setting. METHODS & Statistical Analysis
METHODS Over a one-month period, every other patient who attended the general medicine clinics at Grady Memorial Hospital was screened for the presence of CHD. The clinic was staffed by 140 interns and residents from the Emory University Internal Medicine Residency Program under the supervision of 40 general medicine Emory University attendings. Clinics were held daily with morning and afternoon clinic sessions. One-hundred-forty-seven patients with a clinical diagnosis of CHD were identified after excluding 35 CHD patients with dementia, terminal illness or cancer. Clinical and demographic data (age, gender and race) were collected on all patients by a single, trained chart reviewer. A documented diagnosis of CHD was defined by coronary disease proven by cardiac catheterization, a positive stress test or physician documentation of prior myocardial infarction.
Information on lipid status and lipid therapy was gained by review of the clinic chart and, if needed, the computerized laboratory and pharmacy databases. Chart documentation of a lipid profile within the previous six months was considered the patient’s current lipid status. If no such documentation was made, a review of the laboratory database was used to determine the lipid status within the previous six months. A similar method was used to determine lipid therapy. This study used the recommendations made in the NCEP II guidelines, as the NCEP III guidelines were not published at the time of data collection.

Statistical Analysis All data were entered using double verification and descriptive statistics and univariate associations were calculated using SAS Version 8.0 (SAS Institute, Cary, NC). In addition, we computed categorical independent variables using Chi-squared analysis. For comparison of continuous variables, we used simple Student’s t test analysis. canadian viagra
