     The catheter associated urinary tract infection: CAUTI is an important and frequent infection of the hospital. According to a report by the National Health Care Safety Network (NHSN), CAUTI rate in adult patients in 2011 AD was 0.2-4.8 times per 1,000 devised-days1. At the hospital for Thailand, infection control unit of Prince Songkla Hospital CAUTI rate in ICU patients in 2008-2010 BE was 9.63, 5.03 and 4.49 times per 1,000 devised-days, respectively, 2-3 times higher than hospital indicators2. And from the infection report inpatient department, in the 2557-2559 BE, Phichit Hospital is likely to rise incidence of CAUTI infection3. Urinary tract infection from urinary catheter caused by many factors. Phichit Hospital has not studied the factors that cause urinary tract infection. The researchers want to study such factors. The objective to study factors affecting urinary tract infection in urinary catheter patients. Data sources from reported patients receiving urinary catheters, both infected and non-infected inpatient department of hospital. Systematic Random Sampling was collected from 392 patients. By retrospective study, between October 2558 BE and September 2559 BE, General data analysis by percentage Mean and standard deviation. Analysis of factors related to urinary tract infection from Chi-Square catheter and factors influencing infection by logistic regression analysis. Find a chance with Odd Ratio.

      RESULTS: There were five factors that affecting the incidence of urinary tract infection: including kidney disease, length of stays, devised days, the severity of the disease, co-respiratory disease. All this factors had effect of urinary tract infection inpatients. This can be accurately predicted by 85.1 percent of patients with renal disease. The risk of urinary tract infection was founded approximately three times more likely in patients with kidney disease than other patients, (OR = 3.057) or 95% CI between 1.462 - 6.399. Patients with respiratory disease had 2.5 times more chance of urinary tract infection than other patients, (OR = 2.463) or 95% CI between 1.184 - 5.124. Level of severe of disease, urinary tract infection than patients with more than 2-fold (OR = 2.046) 95% CI between 1.183 to 3.539. The equation is as follows.

-5.088 + 1.12 X1 + 0.07 X2 + 0.05 X3 + 0.72 X4 + 0.90 X5



      By Y = occurrence of the catheter associated urinary tract infection, X1 = kidney disease, X2 = devised days, X3 = length of stays, X4 = severity of the disease, X5 = severe respiratory disease
