Hypothesis
How accurate is the Minimum Data Set (MDS) in reporting medication use compared to Medicare Part D data?
Conclusion
The MDS is a valid tool for measuring antipsychotic and antidepressant use, but there are discrepancies in reporting hypnotic use.
Supporting Evidence
- The MDS showed high agreement with PDE for antipsychotic and antidepressant use.
- Sensitivity and specificity for MDS data compared to PDE were high for antipsychotic and antidepressant medications.
- Only a small percentage of participants identified in MDS used hypnotics compared to PDE.
Takeaway
Researchers checked if a system used in nursing homes to track medication use is correct by comparing it to another system, and found it works well for some medications but not for others.
Methodology
The study compared medication use rates from MDS and Part D Event file data among nursing home residents using Cohen kappa for agreement assessment.
Limitations
The study may not fully capture all discrepancies in medication reporting, particularly for hypnotics.
Participant Demographics
Long-stay nursing home residents enrolled in Medicare Part D, aged ≥ 65 years, with psychiatric disorders or dementia.
