Fig. 2From: Infection-prevention and control interventions to reduce colonisation and infection of intensive care unit-acquired carbapenem-resistant Klebsiella pneumoniae: a 4-year quasi-experimental before-and-after studyEpidemic of observed monthly incidence rate of patients (No. of cases per 1000 ICU patient-days) colonized or infected with CRKP in the intensive care unit during the baseline and different intervention periods. Black bars show the incidence rate of ICU-acquired CRKP positivity, and gray bars represent the incidence rate of CRKP patients at ICU admission surveillance. Trend lines of ICU-acquired CRKP (No. of cases per 1000 ICU patient-days) for each period are shown in black solid bold type, showed a downward incidence rate trend from 10.08 to 2.84 after the implement of modified IPC interventions (P<0.05)Back to article page
