Abstract
Catheter-associated urinary tract infection (CAUTI) is the most common complication in patients with indwelling catheterization. The incidence of CAUTI in my country is still at a relatively high level compared with foreign countries, especially for the ICU, which has a high usage rate of urinary catheters, to focus on prevention and control. This article focuses on studying the risk factors of CAUTI in critically ill patients and discusses targeted preventive care measures. This article investigates and examines the clinical data of CAUTI in critically ill patients. After statistical analysis, the risk factors that affect CAUTI are summarized, so as to derive the cause of CAUTI in order to strengthen clinical care and to further study the prevention, control, and nursing of CAUTI to provide reference. Clinical data shows that the CAUTI infection rate of patients with catheter indwelling ≥7 days is greater than that of patients with catheter indwelling days less than 7 days. The CAUTI infection rate of the patients who change the urine collection bag every day or ≥7 days is greater than that of the patients who change the urine collection bag within 2 to 4 days.
Highlights
Catheter-associated urinary tract infection (CAUTI) refers to the urinary tract infection that occurs in patients after the catheter is indwelled or within 48 hours after the catheter is removed [1, 2]
This article focuses on studying the risk factors of CAUTI in critically ill patients and discusses targeted preventive care measures
With the extension of permanent catheters in ICU patients, the incidence of CAUTI increases. This is because the permanent urinary catheter destroys the normal environment of the urethra, and the immune system weakens the phagocytosis of neutrophils, which affects the physiological role of the bladder on bacteria, making it easier for bacteria to enter the bladder and ureter, and the development of organs in the system and reproduction can cause infection [11, 12]
Summary
CAUTI refers to the urinary tract infection that occurs in patients after the catheter is indwelled or within 48 hours after the catheter is removed [1, 2]. Residential catheterization is a common method in clinical practice. This requires testing this condition, but is a major measure for certain diseases. The study of CAUTI risk factors for critically ill patients is of great significance. This article focuses on studying the risk factors of CAUTI in critically ill patients and discusses targeted preventive care measures. This article investigates and examines the clinical data of CAUTI in critically ill patients. The risk factors that affect CAUTI are summarized, so as to derive the cause of CAUTI in order to Applied Bionics and Biomechanics strengthen clinical care and to further study the prevention, control, and nursing of CAUTI to provide reference
