Consistent ART adherence is associated with improved quality of Life, CD4 counts, and reduced hospital costs in central China.

摘要

This study aimed to assess levels of ART adherence and to examine the relationship between adherence and treatment outcomes. A longitudinal study in Hunan and Hubei provinces used the CPCRA Antiretroviral Medication Self-Report and a 7-day Visual Analogue Scale to assess levels of adherence, while quality of life was evaluated using SF-36. CD4 cell count and the number, duration, and cost of hospitalizations were collected from participant medical records. Measurements were obtained at baseline, month 3, and month 6. A total of 113 participants enrolled and 98 completed the study. The mean level of adherence was 91%, 89%, and 88% at baseline and at 3 and 6 months, respectively. Of participants, 54/98 (58%) reported taking all doses at all three interviews and were classified as consistent adherers (CA). CAs had better physical function (p = 0.001), general health (p = 0.009), vitality (p = 0.016), social functioning (p = 0.001), and mental health (p = 0.023), and presented a higher CD4 cell count (p = 0.028). CAs also had fewer hospital admissions and readmissions (p = 0.005), shorter hospital stays (p = 0.005), and lower hospital expenses (p = 0.006). Consistent adherence is associated with better outcomes including improved quality of life, higher CD4 counts, and lower health care costs.
