Improving adherence to antiretroviral therapy.

Area of Science:

• Infectious Diseases
• Pharmacology
• Public Health

Background:

• Antiretroviral therapy (ART) has shifted HIV from a terminal to a chronic condition.
• Long-term adherence to ART is critical for sustained viral suppression and improved patient outcomes.
• Optimal adherence rates, often cited at 95% or higher, are directly linked to reduced disease progression.

Purpose of the Study:

• To explore the multifaceted factors influencing adherence to antiretroviral therapy (ART) for HIV infection.
• To highlight the significance of adherence for long-term treatment success and viral control.
• To identify key predictors of inadequate adherence and potential intervention strategies.

Main Methods:

• This study synthesizes existing research on factors affecting ART adherence.
• It examines social, lifestyle, financial, and pharmacological aspects influencing patient compliance.
• Predictors of poor adherence and effective intervention levels are discussed.

Main Results:

• Adherence to ART regimens is essential for successful treatment and sustained viral control.
• Higher adherence levels correlate with significantly reduced disease progression.
• Numerous factors, including social support, drug tolerability, pill burden, and patient education, impact adherence.
• Lack of trust, substance use, mental illness, and access to care predict inadequate adherence.

Conclusions:

• Successful long-term HIV management with ART requires a comprehensive understanding of adherence determinants.
• Interventions targeting patient, medication, healthcare, and community levels can enhance adherence and treatment outcomes.
• Addressing psychosocial, economic, and clinical factors is vital for optimizing ART efficacy.
