Antiretroviral therapy: factors associated with adherence

Area of Science:

• Pharmacology
• Public Health
• Behavioral Science

Background:

• Clinical effectiveness of highly active antiretroviral therapies (HAART) is significantly influenced by patient adherence to complex medication schedules.
• Nonadherence can result in suboptimal drug concentrations, which are strongly linked to the emergence of antiretroviral resistance.

Purpose of the Study:

• To highlight the critical role of patient adherence in the success of highly active antiretroviral therapies.
• To underscore the challenges in defining and measuring adherence due to its complex nature.
• To identify key factors influencing adherence to medical regimens.

Main Methods:

• Literature review and conceptual analysis of adherence in the context of antiretroviral therapy.
• Examination of the relationship between adherence, drug levels, and resistance development.
• Exploration of the multifaceted nature of adherence as a dynamic behavioral process.

Main Results:

• Inconsistent definitions and measurement difficulties complicate the assessment of patient adherence.
• Adherence is a dynamic process influenced by regimen, provider, patient, and societal factors.
• Suboptimal adherence is a significant driver for the development of antiretroviral resistance.

Conclusions:

• Accurate measurement and consistent definitions of adherence are essential for evaluating HAART effectiveness.
• Understanding the dynamic interplay of factors influencing adherence is critical for developing effective interventions.
• Improving adherence is paramount to preventing antiretroviral resistance and optimizing patient outcomes.
