All process measure scores and the reporting‐fall‐events score were calculated based on the coordinating team's rating of their frequency or effectiveness using the gap analysis (Appendix S2) at study end. Total, injurious, and unassisted fall rates were measured during the end‐of‐study period January‐July 2014. The repeat fall rate was measured for the duration of the study August 2012‐July 2014.
Outcome multipliers and slopes were calculated for every 5‐unit increase in the fall‐risk‐reduction program coordination score; outcome multipliers and slopes for all other process scores were calculated for every 1‐unit increase in that score.
Statistical significance was calculated using: *a Poisson rate model for the outcome multipliers for the total, injurious, and unassisted fall rates; †nonparametric regression method for the repeat fall rate and the reporting‐fall‐events score (Appendix S2, p. 6); ‡ P < 0.10; § P < 0.05.
