Background and Importance In 2020 Spain was involved in the SARS-CoV-2 pandemic. This situation entailed in the dispensing of drugs from pharmacy services to patients' homes. This way of reaching the patient facilitated the access to antiretroviral treatment (ART) in this difficult situation. However, due to the social stigmas, certain patients did not consent to access this dispensing system.
Aim and Objectives The objective is to study how adherence to antiretroviral treatment was affected in HIV-positive patients during the months of the first alarm state in Spain (March 14 to June 21 2020); because during those period ART was home dispensation.
Material and Methods Observational retrospective study, included patients HIV-positive who received ART during the first alarm state in Spain during COVID-19 pandemic and in the same period of 2019.
Collected data were: sex, age and variables related to pharmacological treatment (ART in the selected periods, number of dispensations made, galenic units dispensed).
To measure adherence, an indirect method was used, comparing the dispensations made in the hospital pharmacy of the hospital of León during the studied period and the same dates of the previous year.
% adherence = [dispensed galenic units/planned galenic units] x100
Results We analyse 444 patients with a median age of 54 years (45-59) being 77.93% (n=346) men.
During the study period 83 patients (18.69%) changed their ART. 38.55% (n=32) carried out a simplification of ART in 2020 (from a treatment based on several pharmaceutical forms to a treatment based on a single one).
The mean adherence in the periods studied in 2019 and 2020 was 91.89% (CI 90.44-92.90) and 90.25% (CI 87.61-92.90), respectively. In 2019, 67.12% (n=298) of patients had adherence greater than 95%, compared to 86.71% (n=385) in 2020.
For 38 patients there are no medication dispensations during the 2020 period. Of the majority (n=27) the reason for the absence is unknown; 6 were not disposed of from the hospital of León for spending the confinement outside the city; 4 have died and 1 did not accept home dispensation.
Conclusion and Relevance The implementation of home dispensing could have positively influenced adherence in HIV-positive patients. It is necessary to evaluate in the future that the implementation of new telepharmacy programmes can have a positive influence on adherence.
