RESUMO
Priority setting is the process through which a country's health system establishes the drugs, interventions, and treatments it will provide to its population. Our study evaluated the priority-setting legal instruments of Brazil, Costa Rica, Chile, and Mexico to determine the extent to which each reflected the following elements: transparency, relevance, review and revision, and oversight and supervision, according to Norman Daniels's accountability for reasonableness framework and Sarah Clark and Albert Wale's social values framework. The elements were analyzed to determine whether priority setting, as established in each country's legal instruments, is fair and justifiable. While all four countries fulfilled these elements to some degree, there was important variability in how they did so. This paper aims to help these countries analyze their priority-setting legal frameworks to determine which elements need to be improved to make priority setting fair and justifiable.

A decrease in the rate of acquired antiretroviral (ARV) drug resistance (ADR) over time has been documented in high-income settings, but data on the determinants of this phenomenon are lacking. We tested the hypothesis that in heavily ARV-experienced patients in the Mexican ARV therapy (ART) roll-out program, the drop in ADR would be associated with changes in ARV drug usage. Genotypic resistance tests obtained from 974 HIV-infected patients with virological failure and at least 2 previously failed ARV regimens from throughout the country were analyzed for the presence of nucleos(t)ide reverse transcriptase inhibitors, non-nucleoside reverse transcriptase inhibitors, and protease inhibitor (PI) resistance-associated mutations (RAMs). Patients were divided into two groups according to their first ART start date: 488 patients initiated ART before mid-2003 (group 1) and 486 after mid-2003 (group 2). The rate of RAMs, median resistance score of several sentinel ARVs, and composition of ART drugs in patient's entire treatment history were compared between both groups. Patients in group 2 were less likely to have >3 thymidine analogue-associated mutations (TAMs) and >3 PI-mRAMs [adjusted odds ratio (aOR) = 0.37; 95% confidence interval (95% CI) = 0.25-0.54; p < .001 and aOR = 0.53; 95% CI = 0.36-0.77; p = .001, respectively] and had a significantly lower resistance score for zidovudine, tenofovir, ritonavir-boosted (r)-lopinavir, r-atazanavir, and r-darunavir than group 1 patients. A significantly lower proportion of patients in group 2 used monotherapy, bitherapy, thymidine analogue-containing regimens, nonboosted PI-containing regimens, and low resistance barrier PI-containing regimens. In Mexican ARV-experienced patients, the occurrence of TAM and PI-mRAM has significantly declined over time. This can be explained by treatment optimization in the national ART roll-out program in recent years.
