Groups2
Group 2 names the comparator: usual care.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Adherence Intervention | Patients in the medication adherence enhanced clinical decision support received the enhanced decision support intervention over a 6 month period. Patients were accrued over 6 months and followed for 12 months at which point they were assessed for improved medication adherence and clinical outcomes. | 470 | 887 | OG001 |
| Group 2 | Usual Care | Patients in the usual care arm received the basic clinical decision support that is considered the standard of care at HealthPartners. Patients in this study group were accrued over 6 months and followed for 12 months at which point they were assessed for improved medication adherence and clinical outcomes. | 396 | 843 | OG000 |
