Healthcare system TAP Strategy implementation for CDI prevention. Observed and predicted (modeled) incidence rates of hospital-onset C. difficile laboratory-identified event (CDI) before and after intervention at the system level and by hospital. Predicted rates were estimated from final predictive models. Time=0 indicates the beginning of the intervention period (ie, completion of Targeted Assessment for Prevention [TAP] facility assessments). The pre- and postintervention periods each lasted for 18 months.
