ObjectiveTo study the effect of standard indwelling urinary catheterization and nursing procedures on reducing the incidence of catheterassociated urinary tract infection(CAUTI).MethodsPlanedocheckact(PDCA) cycle model was used to manage the inpatients with indwelling urinary catheterization, standard manipulation procedures of indwelling urinary catheterization were formulated by analyzing the risk factors of CAUTI, the training, guidance, assessment and check were strengthened to find out the problems and propose improvement measures timely,and the continuous quality improvement was performed.ResultsThrough one year implementation of PDCA cycle management, the qualified rates of routine care for urinary meatus, connection between urinary catheter and urine collection bags, and outlets of urine collection bags, as well as implementation rate of external fixation and signs of catheters were significantly higher than those before PDCA management respectively (98.59%［70/71］ vs 34.92%［22/63］;95.77%［68/71］ vs 28.57% ［18/63］;95.77%［68/71］ vs 17.46%［11/63］; 100.00%［71/71］ vs 0.00%［0/63］); the incidence of CAUTI in neurosurgery patients from quarter 1 to 4 of 2011 was 1.86‰,1.63‰,1.10‰ and 0.95‰ respectively，there was a decreased tendency（χ2=3.951，P=0.047）.ConclusionThe implementation of PDCA cycle model can bring the function of surveillance system into full play, and effectively reduce the incidence of CAUTI.
