Abbreviation: CI, confidence interval.
aRepositioning interval for each intervention arm. Each arm included 3 nursing homes.
bTotal N = 988 because of missing movement data for four residents: arm 2 missing three residents (n = 320); arm 3 missing one resident (n = 349).
cAnalysis of variance used to test for differences among arms.
dMean difference displayed pairwise: arm “x” − arm “y”; value of actual pairwise mean difference; CI (a, b).
eNo. of residents with one or more overdue repositioning Turn Alert cues.
fMean compliance values imputed for four missing residents after determining there is no difference in statistical significance between the analysis of variance results with and without imputation.
gBraden Scale risk category determined from baseline Braden Scale risk scores for the week prior to the Intervention.
