Abstract:
Background:Antiretroviral therapy (ART) has been shown to significantly reduce the likelihood of transmission to other people as well as promoting the health of people living with Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) (PLH). The purpose of this study was to assess the HIV care continuum of PLH in Korea using the national health insurance system (NHIS) database.
Materials and Methods:From 2006 to 2015, ART prescription/laboratory test claim data and enlisted accompanying comorbidities were extracted from the NHIS database. Utilizing these data, proportion of PLH on ART among those who registered to Korea Disease Control and Prevention Agency (KDCA), HIV viral load testing, prescription trends of ART, medication possession ratio (MPR) of ART, and accompanying comorbidities were reviewed. Factors related with MPR <90% was also investigated among demographic factors, ART prescription, and accompanying comorbidities.
Results:During the observation period, the number of people receiving ART prescription increased from 2,076 in 2006 to 9,201 in 2015. Considering the number of PLHs reported by the KDCA, the proportion of PLHs who received ART prescription increased from 55.4% to 87.6% during the study period. The median value of ART MPR increased from 76.4% to 94.2% and the proportion of patients with MPR >90% increased from 54.3% to 78.2%. The most commonly accompanying comorbidities were dyslipidemia (55.7%), osteoporosis (16.3%), hypertension (15.7%) and diabetes (13.7%), respectively. The proportion of PLH with two or more comorbid conditions increased from 22.0% to 31.6%. Regarding the factors associated with suboptimal compliance, age less than 50 years old, under support of National Medical Aid, alcoholic liver disease, mental and behavioral disorders due to use of alcohol, and ART regimen of protease inhibitor and non-single table regimen integrase strand transfer inhibitor were related with MPR <90%.
Conclusion:The proportion of PLHs who received ART prescription and median MPR of ART increased during the study period. However, proportion of patients with MPR >90% was 78.2% in 2015 and there are still much room for improvement in the aspect of compliance.
