Objective To synthesize new findings from the THRIVE Research Collaborative (The Research Initiative Valuing Eldercare) related to the Green House (GH) model of nursing home care and broadly consider their implications. Data Sources Interviews and observations conducted in GH and comparison homes, Minimum Data Set (MDS) assessments, Medicare data, and Online Survey, Certification and Reporting data. Study Design Critical integration and interpretation of findings based on primary data collected 2011–2014 in 28 GH homes (from 16 organizations), and 15 comparison nursing home units (from 8 organizations); and secondary data derived from 2005 to 2010 for 72 GH homes (from 15 organizations) and 223 comparison homes. Principal Findings Implementation of the GH model is inconsistent, sometimes differing from design. Among residents of GH homes, adoption lowers hospital readmissions, three MDS measures of poor quality, and Part A/hospice Medicare expenditures. Some evidence suggests the model is associated with lower direct care staff turnover. Conclusions Recommendations relate to assessing fidelity, monitoring quality, capitalizing opportunities to improve care, incorporating evidence‐based practices, including primary care providers, supporting high‐performance workforce practices, aligning Medicare financial incentives, promoting equity, informing broad culture change, and conducting future research.
