Given the multiple adverse consequences of treatment failure (risk of disease progression, increase in complexity and costs of treatment, and risk of HIV transmission)

engaging patients in treatment decisions and the monitoring and support of adherence are of paramount importance [5] (see Section BGB324 molecular weight 3: Patient involvement in decision-making). Non-adherence is best understood as a variable behaviour with intentional and unintentional causes. Most people taking medication are non-adherent some of the time. Unintentional non-adherence is linked to limitations in capacity or resources that reduce the ability to adhere to the treatment as intended. Intentional non-adherence is the product of a decision informed by beliefs, emotions and preferences [6]. BHIVA recommendations on the monitoring of adherence to ART are available [7]. NICE has published detailed guidance on the assessment

and support of adherence to medication in chronic diseases; key recommendations for adherence support are shown in Box 1 [8]. A ‘no-blame’ approach is important to facilitate open and honest discussion. A patient’s motivation to start and continue with prescribed medication is influenced by the way in which they judge their personal need for medication (necessity beliefs), relative to their concerns about potential adverse effects. Delayed uptake and non-adherence are associated with doubts about personal need for ART and concerns about taking it [9, 10]. Interventions to support adherence should be individualized to address selleck compound specific relevant perceptual and practical barriers. A three-step ‘Perceptions and Practicalities Approach’ [9] may be helpful: Identify and address any doubts about personal need for STK38 ART. Identify and address specific concerns about taking ART. Identify and address practical barriers to adherence. Because evidence is inconclusive, only

use interventions to overcome practical problems if there is a specific need. Interventions might include: suggesting patients record their medicine-taking; encouraging patients to monitor their results; simplifying the dosing regimen; using a multicompartment medicines system; If side effects are a problem: discuss benefits and long-term effects and options for dealing with side effects; consider adjusting the dosage, switching to another combination or other strategies such as changing the dose timing or formulation. Patients’ experience of taking ART and their needs for adherence support may change over time. patients’ knowledge, understanding and concerns about medicines and the benefits they perceive should be reviewed regularly at agreed intervals. In patients where there is clinical concern that doses may be missed intermittently, there is insufficient evidence to recommend a PI/r over EFV-based regimens.
