Family-Focused Adherence Support It may take several weeks and several visits to ready the family for treatment. Before prescribing –Family is part of and agrees with treatment plan –Assess family life-style, priorities, beliefs –Ask about prior medication experience: build on success and work on problems –Educate about the disease, purpose of ARV, importance of adherence –Repeat information as many times as necessary

Family-Focused Adherence Support Planning for a good start: –Develop a simple schedule that fits the family’s daily activities. Consider differences between weekdays and weekends. –Clarify who will be responsible for giving or supervising each dose, each day of the week –Make the schedule visual. Use pictures of pills. Color- code everything. Consider literacy level of family members

Family-Focused Adherence Support Planning for a good start: –Demonstrate medication preparation: measuring volumes of liquids crushing or dissolving tablets opening capsules using foods or liquids to mask task –Do a trial run with “dummy” pills or liquid –Observe medication administration in the office. If possible, start the first dose under supervision –Follow-up with a phone call and/or home visit in the first few days

Conclusions Every HIV/AIDS treatment program should include processes to assess and support adherence Adherence promotion must be multifaceted and multidisciplinary and adapt to changing needs and realities –Many models/approaches in use –Many also need to be evaluated and adapted for local needs Simpler and more tolerable regimens which preserve efficacy are still needed
