Assessing the representativeness of cluster randomized trials: evidence from two large pragmatic trials in United States nursing homes.
Researchers linked data from two large nursing home-based pragmatic cluster randomized trials, the high-dose influenza vaccine trial and the Music & Memory Pragmatic TRIal for Nursing Home Residents with ALzheimer's Disease (METRICaL), to nursing home assessments and Medicare fee-for-service claims. Their objective was to compare nursing home and resident characteristics in randomized facilities to non-randomized and ineligible facilities. Facility-level characteristics of randomized nursing homes in both trials were found to differ considerably from those of non-randomized and ineligible facilities; little difference was found in resident-level characteristics between the three groups. The researchers concluded that future investigation should assess the characteristics of clusters that participate in cluster randomized trials when examining the applicability of trial results beyond participating clusters.

Using Medicare enrollment data to identify beneficiaries in assisted living.
The authors developed an approach for identifying Medicare beneficiaries residing in US assisted living (AL) communities in 2018. Data sources included a national directory of licensed ALs, a file of US addresses and their associated 9-digit ZIP codes (ZIP+4), the Medicare Enrollment Database (EDB), the Master Beneficiary Summary File (MBSF), and the Minimum Data Set (MDS). The cohorts of beneficiaries identified as AL residents exhibited good construct validity; AL residents also showed similar demographic characteristics to the 2018 sample from the National Survey of Long-Term Care Providers. The authors concluded that, as this residential setting continues to grow, future studies will need effective approaches such as their proposed methodology for identifying Medicare beneficiaries who reside in AL facilities in order to evaluate the quality of care they receive.
