A Matched-Sampling Algorithm for the Nursing Home Connection Demonstration
The Nursing Home Connection, a demonstration project sponsored by the Massachusetts Department of Public Welfare, seeks to improve both the quality and cost-effectiveness of care delivered to nursing home patients through the introduction of midlevel providers — nurse practitioners (NPs) and physician's assistants (PAs) — into nursing homes. This Note reports on an innovative sampling strategy that "matches" the treatment and control groups on time in the nursing home, prior use of medical services, patient sociodemographic characteristics, and nursing home characteristics. The sampling strategy is essentially a two-dimensional variant of propensity score matching. Improvements in the comparability of the samples over what would be expected from simple random sampling are reported.
