Abstract:
Background. Awareness of patients' adherence is generally low among primary healthcare physicians when they are given a drug. If drugs are not used appropriately their benefits disappear. Aim. To determine the compliance rate of patients diagnosed of hypercholesterolemia at the end of the first month of a statin therapy and validate several indirect methods of drug-compliance in order to know which of them fit more closely with the actual compliance of the patient. Design. Observational prospective survey.Setting of the study. Primary health care.Subjects. 271 patients belonging to 14 practices of four primary health care centres who were diagnosed of hypercholesterolemia and were susceptible to drug therapy with a statin. Informed consent were asked for even though the true aim of the survey was not accurately explained to them. Measurements and interventions. Visits at home one to three days before ending up the statin were performed in which counting of pills was assessed. Patients who had between 80 and 110% compliance were defined as compliant. The following parameters were analysed: age, gender, high blood pressure, diabetes, cardiovascular risk, polipharmacy (more than five different drugs taken simultaneously), analysis before and after the first month of drug therapy (total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides, and hepatic enzymes). 4 physicians gave simultaneously an explanatory sheet about how to take the statin and the other 10, did not. Furthermore, patients were asked about communication of self-compliance, modified Morisky-Green test and a test of knowledge with 3 questions. Chi-square, Student t, variance analysis, correlations, and validation parameters were used, considering p-values < 0.05 as statistically significant. Results.
