Hypothesis
Can two novel questionnaires effectively measure treatment adherence in Type-2 diabetic patients?
Conclusion
The Medical Prescription Knowledge questionnaire is the most effective tool for identifying non-adherence in Type-2 diabetic patients.
Supporting Evidence
- The study found that only 27% of patients adhered to their treatment.
- The Medical Prescription Knowledge questionnaire had a high negative predictive value of 82.2%.
- Patients with weak medical prescription knowledge had a significantly lower probability of good adherence.
Takeaway
This study created two questionnaires to help doctors understand if diabetes patients are taking their medicine correctly, and one of them worked really well.
Methodology
Two questionnaires were developed to assess patients' knowledge of their medication and their attitudes towards adherence, with pill count used as the gold standard.
Limitations
The study's findings may not apply to all diabetic patients, especially those with complications or on insulin.
