Hospital-acquired infections (HAI) are not uncommon in healthcare facilities. They are usually prevented by sanitation techniques and by maintaining a high standard of care. Catheter-associated urinary tract infections (CAUTI) make up a large percentage of hospital-acquired infections and are often the most preventable type of HAI. Patterns in infection rate could provide new ideas on prevention techniques, which might further reduce infection rate, saving lives and cutting costs. CAUTI infection rate was measured from January KJIY to September KJIL and was differentiated based on hospital ward as well as month and season. Overall, ICU units tended to have a higher CAUTI infection rate than ward units, particularly in January, February, April, and May. The CAUTI infection rate was highest in the ICU units during spring and May, and lowest during fall and October. In the ward units, the CAUTI infection rate was highest during summer and March, and lowest during winter and February.
