RESUMO

OBJECTIVE: We aimed to calculate the efficiency of the EmERGE Pathway of Care in five European HIV clinics, developed and implemented for medically stable people living with HIV. METHODS: Participants were followed up for 1 year before and after implementation of EmERGE, between April 2016 and October 2019. Micro-costing studies were performed in the outpatient services of the clinics. Unit costs for outpatient services were calculated in national currencies and converted to US$ 2018 OECD purchasing parity prices to enable between clinic comparisons in terms of outcomes and costs. Unit costs were linked to the mean use of services for medically stable people living with HIV,  before and after implementation of EmERGE. Primary outcome measures were CD4 count and viral load; secondary outcomes were patient activation (PAM13) and quality of life (PROQOL-HIV). Out-of-pocket expenditure data were collected. RESULTS: There were 2251 participants: 87-93% were male, mean age at entry was 41-47 years. Medically stable people living with HIV had outpatient visits in four sites which decreased by 9-31% and costs by 5-33%; visits and costs increased by 8% in one site, which had to revert back to face-to-face visits. Antiretroviral drugs comprised 83-91% of annual costs: the Portuguese site had the highest antiretroviral drug costs in US$ purchasing parity prices. Primary and secondary outcome measures of participants did not change during the study. CONCLUSIONS: EmERGE is acceptable and provided cost savings in different socio-economic settings. Antiretroviral drug costs remain the main cost drivers in medically stable people living with HIV. While antiretroviral drug prices in local currencies did not differ that much between countries, conversion to US$ purchasing parity prices revealed antiretroviral drugs were more expensive in the least wealthy countries. This needs to be taken into consideration when countries negotiate drug prices with pharmaceutical vendors. Greater efficiencies can be anticipated by extending the use of the EmERGE Pathway to people with complex HIV infection or other chronic diseases. Extending such use should be systematically monitored, implementation should be evaluated and funding should be provided to monitor and evaluate future changes in service provision.

RESUMO

BACKGROUND: Polypharmacy (use of ≥ five medications) increases the risk of drug-drug interactions and can lead to negative health outcomes. This study aimed to review the medications of people living with HIV (PLWH) and HIV-negative controls in the POPPY study and evaluate the frequency of polypharmacy and potential drug-drug interactions (PDDIs). METHODS: PDDIs between non-antiretroviral (ARV) drugs were analysed using the Lexicomp® database, and PDDIs between non-ARV and ARV drugs using the Liverpool drug interaction database. Between-group differences were assessed using χ2, Mann-Whitney U and Kruskal-Wallis tests. RESULTS: This analysis included 698 PLWH ≥50 years, 374 PLWH <50 years and 304 HIV-negative controls ≥50 years. The prevalence of polypharmacy was 65.8% in older PLWH, 48.1% in younger PLWH and 13.2% in the HIV-negative group. When ARVs were excluded, 29.8% of older PLWH and 14.2% of younger PLWH had polypharmacy. The prevalence of ≥1 PDDI involving non-ARV drugs was 36.1%, 20.3% and 16.4%, respectively, in older PLWH, younger PLWH and HIV-negative controls. In PLWH the prevalence of ≥1 PDDI involving ARV and non-ARV drugs was 57.3% in older PLWH and 32.4% in younger PLWH. CONCLUSIONS: Polypharmacy and PDDIs involving non-ARV/ARV drugs and non-ARV/non-ARV drugs were common among older PLWH, highlighting the need for increased awareness and additional research on all types of PDDI.
