Hand hygiene intervention on general ICU acquired methicillin- resistant staphylococcus aureus infection and improvement

Abstract

Objective To discuss the influence hand hygiene intervention on general ICU acquired methicillin- resistant staphylococcus aureus (MRSA) infection and its improvement. Methods Hand Hygiene Cognition Questionnaire that passed the reliability and validity test was used to compare the change of cognition on hand hygiene of medical staff. According to the results of the questionnaire, the intervention was carried out by continuous intensive training. The compliance with hand hygiene of medical staff was observed by monitoring equipment in the ward. Implementation status and effect of hand hygiene of medical staff on duty were examined randomly each month. At the same time MRSA infection rate of patients in comprehensive ICU was monitored in the same period. The relationship between hand hygiene compliance and MRSA infection rate was analyzed. Results The score of medical staff of cognition of hand hygiene was (41.70±3.67) points before the intervention, while the score was (44.10±3.55) points after the intervention. The difference had statistical significance (t=24.37, P <0.01). The correct rate of hand washing, positive rate of bacterial culture in hand, hand hygiene compliance and infection rate of MRSA of patients in comprehensive ICU were 68.75% , 14.58% , 66.90% , 12.90% respectively before the intervention. The correct rate of hand washing, positive rate of bacterial culture in hand, hand hygiene compliance and infection rate of MRSA of patients in comprehensive ICU were 88.54%, 3.12%, 74.14%, 3.10% respectively after the intervention. The difference had statistical significance (χ2=7.809- 24.520, P <0.01). Conclusions Questionnaires with high credibility reviews could better identify issues in hand hygiene compliance, and sustained, reinforcing intervention measures could improve the compliance of hand hygiene; Good hand hygiene practice of medical and nursing staff contributes to controlling MRSA infection rates in general ICU.
