HIV/Adheresm

A-CASI for self report of compliance with HAART therapy.


Assessment of patients' regimen understanding.

Research has revealed that patients commonly misunderstand their regimen, resulting in unintentional nonadherence. Patients select their medications by clicking on pictures of antiretroviral medications. A mediset metaphor provides a graphical interface for the patient to interactively "build" their regimen.

3-day adherence assessment.

The patient reports the total number of doses missed over the past three days. The self-reported. The mediset metaphor continues in this section, as the patient clicks on the pills or doses missed.

VAS Scale estimates of adherence over the past seven and thirty days.

Clicking on a VAS (visual analog scale) records the patient estimate of seven and thirty day adherence. Some recent research suggests that a color-gradient scale (green - yellow - red) may elicit more accurate responses. You can choose the style of graphic image.

Reasons for missed doses.

When patients acknowledge missed doses, they are prompted to select their reasons for missing doses from a pre-defined list. If more than one reason is selected, a follow-up question asks about the primary reason for missing doses. The primary reason triggers tailored feedback messages during the intervention portion.

An adherence intervention

An increasing body of research suggests that individually tailored intervention feedback is more effective than generalized feedback.

HIV/Adhere retains patients' responses. Each time a patient uses it, responses from the current and previous interviews are considered in tailoring feedback.

Patient report

The patient report includes the patient's regimen, adherence and risk category based on the patient's responses, the patient's most recent CD-4 and viral load lab test results, and a brief explanation, plus the computer-tailored feedback messages delivered during the assessment.

HIV/Adhere may be combined with additional questionnaires. Often HIV adherence assessments are accompanied by assessments for depression, alcohol/drug use and sexual risk.

HIV/Adhere was implemented with CASIC Builder™, a flexible browser-based platform for the development of medication and other health questionnaires.
