Abstract

PURPOSE: To examine the performance of an instrument to assess adherence based on a visual analogue scale, compared to an instrument based on 3-day recall, using unannounced pill counts in the place of residence as the gold standard. METHOD: We prospectively assessed adherence to antiretroviral therapy in 84 marginally housed indigent HIV-infected patients who were receiving stable antiretroviral therapy in San Francisco, California, with three adherence assessments over no more than 4 months. RESULTS: Mean adherence using the visual analogue scale, 3-day recall, and unannounced pill count methods were 82.5%, 84.2%, and 75.9%, respectively. The correlation between visual analogue scale and unannounced pill count was high (r = 0.76) and was not statistically different from that between 3-day recall and unannounced pill count (r = 0.71; p =.52). Both methods were also similarly inversely correlated with HIV viral load (r = -0.49 and -0.34, respectively; p =.22 for the difference in the correlations). The visual analogue scale correlation with unannounced pill count was stable over time and remained high in all subpopulations examined. CONCLUSION: A visual analogue scale to assess adherence was performed as well as a more complicated 3-day recall instrument in this diverse population. Given its simplicity, the visual analogue scale adherence instrument will be useful in research and may be useful in routine patient care.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
