Mezey and colleagues33 also conducted a survey of hospitals that implemented NICHE to determine what aspects of the NICHE program were adopted. One-hundred thirty-seven hospitals implementing NICHE in 2002 were surveyed, and 103 hospitals responded. The majority of hospitals reported using the GRN model, best practice protocols, the NICHE listserv, and hospital benchmarking protocols. Hospitals were likely to use more than one NICHE tool. The most popular programs were the GIAP survey and GRN model. NICHE was most commonly used to reduce and monitor falls, restrains, and pressure ulcers.
