043) and at follow-up 6–12 months later (P=0.017). There were weaker nonsignificant associations with VL in treated patients (Table 2). Higher scores on ‘medical decision’ were also related to higher CD4 cell count at baseline

(P=0.034). The relationship between concordance and CD4 cell count at baseline remained significant after controlling for treatment status (on treatment/stopped treatment) (P=0.019) as did the relationship between concordance IDO inhibitor and CD4 cell count 6–12 months later after controlling for treatment status and baseline CD4 cell count (P=0.043) (Table 4). Higher concordance was associated with on average a CD4 count that was 84 cells/μL higher at questionnaire completion, and 51 cells/μL higher at 6–12 months, after adjusting for treatment status (and baseline CD4 count for the latter). The relationship between ‘medical decision’ and CD4 cell count at baseline remained significant after controlling for ethnicity (P=0.011) (see Table 4). The relationship between concordance and CD4 cell count at baseline remained significant when quality of life-anxiety/depression

was added to the regression model [unstandardized coefficient (B) (standard error (SE))=86.21 (36.46), P=0.019, n=138] as did the relationship between concordance and CD4 cell count 6–12 months later [B (SE)=53.64 (25.91), P=0.040, n=130]. To test whether adherence (defined as doses missed last week) mediated the relationship between concordance and CD4 cell count, a subgroup analysis Hydroxychloroquine mouse was run on only patients on treatment. The relationship between concordance and CD4 cell count at baseline was similar [B (SE)=70.61 (37.61), P=0.063, n=127] and this trend remained after we added adherence to the linear regression model [B (SE)=67.93 (37.79), P=0.075, n=126]. The relationship between concordance Demeclocycline and CD4 cell count at 6–12 months was significant after controlling for baseline CD4 cell count [B (SE)=58.15 (26.85), P=0.032, n=121] and was not changed after we added adherence to the linear regression model [B (SE)=59.39 (27.12), P=0.030, n=120]. In this study, high levels of concordance, with

positive implications for patient wellbeing, were found during HIV treatment switch decision-making. Observed concordance was higher than that reported by Elwyn et al. [11] in consultations in GP. Given the pivotal role of adherence for maximum success of HAART, doctors might be more likely to take patients’ experiences into account when treatment decisions involve switching antiretrovirals. In the United Kingdom, HIV care is ‘open access’ and patients can move freely from one clinic to another to find services that are felt to be a ‘good fit’, which may result in higher concordance. Alternatively, the difference may be a reflection of the self-reported nature of our data rather than third-party observer reports.
