Estudio de costos - efectividad entre la Clortalidona y Diltiazen en el tratamiento de la hipertensión sistólica en pacientes atendidos en el Servicio de Cardiología en el Hospital del Instituto Ecuatoriano de Seguridad Social Riobamba

Abstract

In the cost-effectiveness study between Chlorthalidone and Diltiazem in the treatment of Systolic Arterial Hypertension in patients attended in the Cardiology service at the IESS Hospital in Riobamba. Sixty male and female outpatients between 30 and 70 years of age were randomly selected during a period of 60 days in the months of August-September 2013. For this purpose, patients were directly interviewed and their medical records were reviewed to collect general data. The patients' blood pressure was taken every week, obtaining a total of nine data at the end of the investigation. With the blood pressure data, the most effective treatment was determined by comparing statistical tables and tests (t-Student and F-Snedecor), obtaining that with Chlorthalidone 96.7% of patients reached optimal blood pressure in less time and with Diltiazem only 20% did so with Diltiazem. Then the study of direct and indirect costs generated in the treatment was carried out and it was obtained that Chlorthalidone generates less economic expenses. It was concluded that Chlorthalidone is more convenient in terms of cost-effectiveness in the treatment of systolic hypertension compared to Diltiazem used for the same purpose. It is recommended to the IEES Hospital of Riobamba to carry out cost-effectiveness studies with different groups of drugs to guarantee health in an effective and economical way.
