Table 1 Rates of medication administration errors
Type of error | Pre-intervention number of errors (% of OE) | Post-intervention number of errors (% of OE) | 95% CI* | p value* | 95% CI (adjusted for heterogeneity) for the coefficient in the fitted logit model corresponding to the `period' indicator.
