[Analysis of the concordance between theoretical and real stratification in patients living with HIV infection treated at a tertiary care hospital].

Introduction: To analyse the concordance between theoretical and actual stratification of people living with HIV infection attending a pharmaceutical care outpatient clinic in a tertiary regional hospital.

Material and methods: Observational, retrospective, analytical, cross-sectional and single-centre study in people living with HIV infection. Study period: April 2024. Inclusion criteria: patients with HIV infection aged over 18 years who had been receiving active antiretroviral therapy (ART) for at least two years prior to inclusion. The 2022 version of the pharmaceutical care stratification model for people living with HIV infection was used. Reliability was evaluated from a qualitative perspective using Cohen's Kappa coefficient.

Results: Of the 199 patients attended during the study period, 100 were consecutively selected, of whom 93 were ultimately stratified. Men accounted for 77.41% of the cohort, with a mean age of 47.81 ± 12.53 years. The obtained stratification percentages were: Priority 1: 7.52%; Priority 2: 26.88%; Priority 3: 65.59%. Quantitative analysis of concordance between the models yielded a Cohen Kappa value of K=0.866.

Conclusions: There is a good concordance between the distribution percentages of the theoretical stratification and the actual one obtained in our study.
