A comprehensive adherence package significantly improved self-reported adherence to antiretroviral therapy in the short term. This intervention showed reduced missed doses in the last 4 and 7 days, but not over 28 days.

Area of Science:

  • Public Health
  • Infectious Diseases
  • Clinical Pharmacy

Background:

  • Adherence to antiretroviral therapy (ART) is crucial for managing HIV/AIDS.
  • Suboptimal adherence can lead to treatment failure and drug resistance.
  • Comprehensive adherence interventions may enhance patient compliance.

Purpose of the Study:

  • To evaluate the effectiveness of a multifaceted adherence package on self-reported adherence to ART.
  • To assess the impact of the intervention on viral load and CD4 lymphocyte counts.

Main Methods:

  • A randomized step wedge design involving 43 participants was employed.
  • The adherence package included education, individualized regimen planning, and choice of adherence aids.
  • Self-reported adherence was measured using the Morisky score and missed doses over different timeframes.

Main Results:

  • A significant reduction in missed ART doses was observed for the last 4 days (P=0.03) and 7 days (P=0.005).
  • No significant changes were found in viral load or CD4 lymphocyte counts post-intervention.
  • The Morisky score showed a significant difference between pre- and post-intervention periods (P=0.006).

Conclusions:

  • The comprehensive adherence package effectively improved short-term self-reported adherence to antiretroviral therapy.
  • While short-term adherence improved, long-term adherence and clinical outcomes like viral load require further investigation.
  • Patient-centered adherence strategies are vital for optimizing HIV treatment outcomes.
