Objectives: To describe the contemporary comorbidity profile and treatment burden among patients with HIV-1 infection. MethOds: A retrospective study utilizing Medicaid claims data from 4 states was conducted. Patients with ≥ 1 antiretroviral (ARV) claim in 2016-2017 (most recent claim defined the index date), ≥ 1 HIV diagnosis within one year prior to index, age ≥ 18 years at first HIV diagnosis and < 65 at index, ≥ 12 months of continuous eligibility prior to index, and no history of HIV-2 were included. Comorbidities, concomitant medication use, and pill burden were assessed in the years prior to index. Stratified analyses were conducted in patients < 50 and ≥ 50 years. Results: Among 3,456 study patients, the mean (standard deviation [SD]) age was 47.1 (10.4) years; the majority were Black (55.1%) and male (62.8%). In the year prior to index, mean (SD) daily pill burden was 2.1 (1.4) for ARVs and 5.9 (5.9) for non-ARVs. Patients ≥ 50 years had higher daily pill burden (2.3 [1.5] ARVs, 6.9 [6.5] non-ARVs) than patients < 50 years (2.0 [1.3] ARVs, 5.0 [5.2] non-ARVs). Older patients had higher rates of comorbidities compared to younger patients (cardiovascular disease [CVD] 51.6% vs. 30.7%, hypertension 46.6% vs. 28.5%, asthma/ chronic obstructive pulmonary disease [COPD] 22.8% vs. 14.7%) in the year prior to index. Among all patients, the prevalence of comorbidities generally increased over time: 27.9% of patients had CVD in the fourth year prior to index, which increased to 40.3% in the first year prior to index. Similar increases were seen for hypertension (24.3% to 36.8%), hyperlipidemia (11.5% to 16.8%) and asthma/COPD (12.7% to 18.4%). Concomitant medication use corresponding to these comorbidities slightly increased over time. cOnclusiOns: As patients with HIV live longer, their comorbidities and corresponding concomitant medications increase. Treatment guidelines suggest that streamlined ARV regimens may be considered as patient complexity evolves over time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
