This goal of improvement plan is in order to protects patients of the respiratory care center from getting urinary tract infection and promote the quality of nursing care, reduce the cost of disbursement, according to studies the demonstration, the decade in Taiwan area, urinary tract infection almost occupies the first place which in the courtyard infects (Jan, Guo, HUANG and so on, 2,000). UTI with Foley catheter insertion has relevance 80% .We found the incidence rate of UTI is around 9.3% but increase up to 132% in February, However the author discovered the unit secretes the urethra to infect the average formation rate is 9.3%, when February actually increases to 13.2%, therefore; we established the special case group for the UTI study of RCC patient. After passing through the group to analyze those questions is: (1) this unit not followed by the hospital ward characteristic specially to subscribe decides protocol of management of Foley catheter insertion (2) the nursing staff to carry out the catheterization technology not follow standard (3) Foley catheter left inside of patient over time. Solution: (1) according to the hospital ward characteristic, formulates this standard f of nursing care for leaving alone the catheterization tube (2) to unify the standard or technology of leavening alone the ureter (3) to design standard of the early wiping out Foley (4) to educate, guide and pass on the next shift for the execution (5) truly to check the measure. The result demonstration of the infection percentage was 5.1 in November, has achieves the goal, but the rate of clear fineness for Foley, reduces the ratio of patient with foley left inside, not to still reach the standard in advance, if could continue the monitor and tracing, the revision, we strongly believe it would be able to have the good achievement in the future, also wish this special case refer to other unit this to promote the higher quality service quality.
