Application of process quality monitoring for the control of hospital infection in ICU

Abstract

Objective To explore the effect of process quality monitoring for hospital infection control of ICU. Methods A total of 265 critically ill patients admitted to ICU were chosen as the control group from April 1, 2014 to March 31, 2015, who were strictly enforced three cluster strategies to prevent catheter related blood stream infection (CRBSI), catheter-associated urinary tract infection (CAUTI) and ventilator–associated pneumonia (VAP) with periodical data monitoring in ICU. Another 292 critically ill patients admitted to ICU were chosen as the observation group from April 1, 2015 to March 31,2016, who were added 3 measures of process quality monitoring on the basis of implementation method of the control group. The incidence of CRBSI, CAUTI and VAP time were compared between two groups. Results There was statistically significant difference on the incidence rate of the CRBSI between the two groups (χ2=4.504, P=0.034), which was respectively 1.79% (5/280) and 5.10% (13/255). There was statistically significant difference in the incidence rate of CAUTI between the two groups (χ2=5.708, P=0.017), which was respectively 3.48% (10/287) and 8.27% (21/254). There was statistically significant difference on the incidence rate of VAP between the two groups (χ2=8.291, P=0.004), which was respectively 3.48% (10/287) and 8.27% (21/254). Mean time of mechanical ventilation in the observation group and the control group was respectively (2.14±1.40) days and (3.37±2.01) days, there was no significant difference (P=0.073). Mean time of ICU stay in the observation group and the control group was respectively (6.04±1.04) days and (11.92±1.90) days, there was statistical significance (t=-1.840, P=0.024). Number of qualified central venous catheter maintenance, perineum clean and oral care had negative relevance with number of patients with CRBSI, CAUTI and VAP, correlation coefficient in the observation group was respectively -0.701, -0.618, -0.677, there was statistical significance (P < 0.05). Conclusions The implementation of quality monitoring can reduce the number of patients with CRBSI, CAUTI and VAP, which suggests wide application in ICU.
