Patient-Reported Nonadherence to HAART Is Related to Protease Inhibitor Levels
Bibliographic record
Abstract
OBJECTIVE: To compare self-reported nonadherence with antiretroviral therapy (ART) with predose plasma levels of protease inhibitor (PI). DESIGN: A cross-sectional study of consecutive patients from a university-based HIV clinic in Rome, Italy, was conducted. One hundred and forty HIV-infected patients were prescribed regimens containing ritonavir or indinavir. A patient questionnaire assessing knowledge of treatment regimen, adherence behavior, reasons for taking and missing therapy, factors influencing adherence, and health behaviors was administered. A predose PI plasma level was measured concurrently. RESULTS: By patient report, 12% missed at least one dose "yesterday," and 24% missed doses in the last 3 days; 14% had a predose plasma concentration below the assay limit of quantitation (2 ritonavir and 18 indinavir samples). Confusion, poor psychological well-being, long office wait, running out of drugs between visits, having relatives to remind the patient to take medication, children, and alteration of sense of taste were related to unquantifiable predose levels of PI. In multivariable analysis, reported nonadherence (odds ratio [OR], 15.8; 95% confidence interval [CI], 4.0-63.3) and confusion (OR, 9.9; 95% CI, 1.4-69.6) were related to unquantifiable predose levels of PI. CONCLUSION: Self-report of missing a dose of antiretroviral medication "yesterday" was related to an unmeasurable plasma PI level.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
