Assessing compliance of cardiologists with the national cholesterol education program (NCEP) III guidelines in an ambulatory care setting

INTRODUCTION: The NCEP III -ATP guidelines provide clear clinical directives for lipid management especially statins therapy in appropriate patient groups. Compliance of primary care physicians with these guidelines especially in ambulatory care settings has been shown to be poor. The compliance of cardiologist to these guidelines is less documented. METHODS: A retrospective chart review of 386 patients managed in a large urban cardiology practice was undertaken. Patients with documented contraindications to use of statins were excluded from the study. Only patients with two or more years of follow-up in the practice were included. Demographic variables and medical history including CAD or its equivalent and its major risk factors were identified. The proportion of patients on statins and adequacy of statins therapy were recorded. The lipid profiles of all patients were also analyzed. RESULTS: Fifteen patients with documented contraindications to statins therapy including persistent/severe LFT abnormalities, allergies, and gastrointestinal intolerance were excluded. A total of 371 patients were included in the analysis. The mean age for patients in the study was 65 years (range: 42–84). 236 (64%) were males while 141 (36%) were females. 161 (43%) patients were on statins while 210 (57%) weren't. 88 (62%) of females were on stain compared to 116 (49%) of males (p = 0.001). 68% of patients below the age of 50 yrs were not on statins compared with 55% of those greater than 50 yrs (p = 0.01). 38% of patients on statins therapy had sub-optimal lipid profile despite greater than two years of therapy. No statistically significant differences in race and use of satins were noted. CONCLUSION: This study demonstrates a higher than expected prevalence of sub-optimal management of dyslipidemia among patients with established coronary heart disease without contraindications to statins managed by cardiologists. Cardiology and primary care practices require similar comprehensive routine lipid management program that is assiduously maintained and evaluated at both in-patient and out patient settings to ensure most patients receive optimal therapy with statins and other lipid lowering agents
