Applying small tests of change to advance infection prevention in nursing homes.

In nursing homes (NHs), infection prevention and control quality assurance and performance improvement activities using structured methodologies are poorly defined. Small tests of change (STOC) are small-scale projects designed to test interventions quickly. This study describes STOCs implemented by 24 NHs participating in a 12-month long collaborative to reduce healthcare-associated infections. With limited external project team support, facilities developed targeted STOCs. Findings highlight how NHs can effectively initiate STOC projects to enhance infection prevention and control outcomes.
