Abstract

Study Objective. To examine adherence measures with different stimulants in children and adolescents. Design. Retrospective analysis. Data Source. Texas Medicaid prescription claims database. Patients. A total of 9549 patients aged 5–18 years with attention‐deficit—hyperactivity disorder. Measurements and Main Results. Paid prescription claims for newly started stimulants during the 2001–2002 school year were extracted from a database; 28,344 prescriptions (9549 patients) were available for analysis. Adherence was evaluated based on the drug therapy prescribed (i.e., mixed amphetamine salts, immediate‐release methylphenidate, and extended‐release methylphenidate—OROS [oral‐osmotic formulation]) and the age and sex of the patient. Adherence measures were persistence and medication possession ratio (MPR). Persistence was higher for extended‐release methylphenidate—OROS (0.50 ± 0.33) than for mixed amphetamine salts (0.42 ± 0.29) or immediate‐release methylphenidate (0.37 ± 0.26; p<0.001). The MPR was also higher for extended‐release methylphenidate—OROS (0.76 ± 0.37) than for mixed amphetamine salts (0.73 ± 0.37) or immediate‐release methylphenidate (0.69 ± 0.37; p<0.001). Patients aged 5–9 years had equal or better persistence and MPR than those aged 10–14 and 15–18 years (p<0.001). No sex‐related differences in adherence were observed. Conclusion. Adherence measures in our study were low. Although they were significantly better for extended‐release methylphenidate—OROS than the other stimulants, the clinical significance of these differences are unclear. Further research should be conducted regarding pharmaceutical products, administration methods, and clinical interventions that may enhance 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.
