Abstract

Background: The prolonged current survival of human immunodeficiency virus (HIV) patients exposes them to new problems arising from the comorbidities they face. Objectives: To describe the situation of comorbidities, polypharmacy, therapeutic complexity and adherence in people living with HIV over 65 years of age and to assess the presence of potentially inappropriate prescriptions (PIP) by applying deprescription criteria. Methods: Observational study including HIV people (> 65 years) from a university tertiary level hospital. Demographic, clinical and pharmacotherapeutic characteristics of the patients and their treatments were studied. The prevalence of polypharmacy (> 5 medications) and the pharmacotherapy complexity, quantified by the Medication Regimen Complexity Index (MRCI), were calculated. Therapeutic adherence was assessed by the Simplified Medication Adherence Questionnaire (SMAQ) and the medication possession ratio, according to prescription dispensing records. The Screening Tool of Older People’s Prescriptions (STOPP) and List of Evidence-baSed depreScribing for CHRONic patients (LESS-CHRON) criteria were applied to identify PIP. Main outcome measure: PIP in elderly people living with HIV. Results: Thirty patients were included, 73% of whom were men, with a median age of 71 years (IQR 67 − 76) and a median duration of infection of 17 years (IQR, 9 − 21). Seventy percent of the patients suffered from dyslipemia, 66.7% from hypertension, 43.3% from diabetes and 26.7% from mental health disorders. Seventy percent of the patients took more than 5 medications and 30% more than 10. The MRCI of concomitant medications was higher (18.3 points) than the MRCI of antiretroviral therapy (5.1 points), 66.7% of the studied population was classified as adherent. Finally, 70% of the patients present some PIP according to the STOPP or LESS-CHRON criteria. The polypharmacy was significantly associated (p = 0.008) with meeting deprescription criteria. Conclusion: The elderly people living with HIV present numerous comorbidities and met the criteria for polypharmacy. Their pharmacotherapy complexity is mainly determined by the concomitant treatments. There is a high prevalence of meeting deprescription criteria in people living with HIV over the age of 65 and a clear relationship between polypharmacy and deprescription. The optimization of pharmacotherapy is necessary in this population.
