Adherence to the 2018 American College of Cardiology and American Heart Association Guideline on the Management of Blood Cholesterol in ambulatory care settings: A cross-sectional study

Abstract

Background: Dyslipidaemia is a major risk factor for heart disease. Adherence to treatment guidelines can help manage dyslipidaemia and decrease the incidence of complications. Aim: To assess the adherence to the 2018 American College of Cardiology/American Heart Association Guideline on the Management of Blood Cholesterol by healthcare providers who assessed ambulatory patients for dyslipidaemia in Jordan. Method: This was a multi-centre, prospective cross-sectional study. Adult patients assessed for dyslipidaemia were invited to participate in the study. Each patient’s therapeutic plan was compared to the recommendations in the 2018 American College of Cardiology/American Heart Association Guideline, and adherence to the guideline was documented. Results: Three hundred patients were recruited. Twenty-eight patients (9.3%) were secondary prevention patients with a history of atherosclerotic cardiovascular disease. Of the 160 primary prevention patients, 83 (51.9%) were excluded from the analysis due to an inability to calculate the 10-year atherosclerotic cardiovascular disease risk, either due to missing information or the patient’s age being under 40. One-quarter of secondary prevention patients were initiated on therapeutic plans according to the guideline. None of the primary prevention patients that required statin initiation according to the guideline were initiated on statins. Conclusion: Adherence to the 2018 American College of Cardiology/American Heart Association Guideline on the Management of Blood Cholesterol for ambulatory patients assessed for dyslipidaemia was suboptimal. Missing patient information that hinders the calculation of the 10-year atherosclerotic cardiovascular disease risk score needs to be addressed to facilitate compliance with the guideline.
