[Prevalence of medicare antiviral drugs use and related factors in HIV-infected people in Ningbo].

ABSTRACT

Objective: To analyze the use of medicare antiviral drugs (ART) and related factors among HIV-infected people in Ningbo City. Methods: The retrospective data was collected related to infection and treatment of HIV-infected people in ART in Ningbo up to February 2023 through the National Infectious Disease Surveillance System. Binary logistic regression was used to analyze the factors related to medicare antiviral drug use in HIV-infected people. R 4.2.2 software was used for statistical analysis. Results: A total of 6 433 HIV-infected people with ART records were collected, among which 5 783 were in ART. The prevalence of medicare drugs use among people in ART was 24.8% (1 435/5 783, 95%CI 23.7%-25.9%). Beilun District (8.7%, 43/497) and Fenghua District (5.7%, 14/247) had the lowest level in medicare drugs use. Among people in ART using medicare or out-of-pocket drugs, the prevalence of those who had at least one viral load test in the last year (84.9%, 1 352/1 593) was significantly lower than that of those using free drugs (91.4%, 3 829/4 190) (χ2=52.50, P<0.001). The results of multivariate logistic analysis showed that the factors influencing medicare drug use included low educational level (junior high school and below aOR=0.24, 95%CI0.17-0.34), farmer or worker (farmer aOR=0.60, 95%CI 0.39-0.91; worker aOR=0.42, 95%CI 0.27-0.64), low monthly income (<3 000 Yuan aOR=0.29, 95%CI 0.18-0.45), the longer interval time between diagnosis and treatment (≥21 days aOR=0.47, 95%CI 0.30-0.74). Conclusions: Significant regional differences on the prevalence of medicare antiviral drugs use in HIV-infected people exist in Ningbo City. Follow-up management program of patients should be improved to strengthen patient compliance to mobilize medicare drug promotion. Meanwhile, publicity of medicare drugs should be strengthened for farmers or workers with low education level and patients with delayed treatment.
