Seguimiento farmacoterapéutico de pacientes chilenos con infección por VIH/SIDA hospitalizados en un centro de alta complejidad durante un período de un año

Abstract

Background: Pharmaceutical follow-up consists on the detection, prevention, and resolution of drug-related problems (DRP) in a continuous, systematized, and documented way. DRP is a health problem connected to pharmacotherapy, which can interfere with the expected health outcomes in the patient. Aim: To make a pharmacotherapeutic surveillance in HIV/AIDS inpatients attended at “Hospital San Juan de Dios” throughout a year prospective study (January to December 2012). Results: 88.6% (93/105) of patients were in stage AIDS with a median of CD4+ lymphocytes of 29 cells/mm3 and a viral load of 107,000 RNA copies/mL. The 16.2% were admitted to a intensive care unit ICU. 296 DRP (DRP 2.8 per patient) were detected, 72% of DRP (n; 213) were associated with treatment safety, 94 were adverse reactions, 19 required dose adjustments, and 6 interactions had a negative clinical impact; 23.3% (n: 69) experimented the necessity to add or remove a drug and 4.7% (n: 14) presented problems associated with effectiveness. A statistically significant relation was observed when associating the number of DRP with admittance to the ICU and the use of more than six drugs. Conclusion: The results allow the conclusion that inpatients present drug-related problems mainly related to toxicity, becoming risk factors for the development of them admittance to ICU, and concomitant use of more than 6 drugs.
