Compliance with inhaled medications: the relationship between diary and electronic monitor
Abstract
Self-report is a frequently-used method of assessing compliance with prescribed medications in patients with chronic illnesses. Most researchers agree, however, that self-report misrepresents patient adherence to regimen prescription. In this randomized, controlled study evaluating inhaler medication compliance, diary data was compared to electronic monitoring in 55 adults with asthma. Subjects randomized to the treatment group received a six-week self-management program. An electronic monitor, the MDI Chronolog, was used in this study to assess inhaler use. The MDI Chronolog records the date and time of each inhaled activation. The self-report measure used was a daily asthma diary. Subjects were asked to use their inhaled medications as usual and record the date and time they administered their medication over a one-week period. Moderate correlations (rs = .55, Mdnd = 95.8, Mdnc = 91.6) were found when comparing the number of administrations calculated using the MDI Chronolog to the number of administrations reported in the subject's diary. When the dosing interval was examined, however, the correlation was weaker (rs = .44, Mdndiary = 92.8, Mdnchronolog = 37.5). In each case, self-reported compliance was higher than monitored adherence.

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.
