Impact of Care Bundle Implementation on Incidence of Catheter-Associated Urinary Tract Infection: A Comparative Study in the Intensive Care Units of a Tertiary Care Teaching Hospital in South India

Introduction: Implementation of evidence-based infection control practices is the need of hour for every institute to reduce the device-associated infections, which directly reflects the quality of care. As catheter-associated urinary tract infection (CAUTI) is the most common nosocomial infection, the study was planned to evaluate the impact of the catheter care bundle in reducing CAUTI incidence. Material and methods:The prospective interventional study before and after the trial study was carried out in adult intensive care units over a period of 9 months (April-June 2017-pre-implementation phase; July-September 2017-training of healthcare worker and implementation of catheter care bundle; October-December 2017-post-implementation phase). Catheter-associated urinary tract infection rates pre- and post-implementation were expressed as incidence rates with Poisson confidence interval. Results: Statistically significant reduction was found in the incidence of CAUTI (60%-from 10.7 to 4.5 per 1,000 catheter days).The key factors that contributed were significant reduction in device utilization ratio (from 0.71 to 0.56) and average catheter days per patient (from 4.8 to 3.7). This holistic approach has resulted in less incidence of CAUTI even among patients with risk factors and prolonged catheter days. Neuro ICU showed drastic improvement compared to other ICUs due to the poor baseline status of their care practices. Conclusion: Adherence to all elements of care bundle brought a significant decrease in CAUTI. Implementing care bundle and auditing the adherence to each element should be included as a part of routine hospital infection control committee (HICC) practices. Clinical significance: Hospital-acquired infection directly reflects on the quality care of the hospital. Bundle care is an 'all or none" phenomenon. Adherence to each element will have some influence in reducing CAUTI in terms of reducing the device utilization ratio and average catheter days per patient. Auditing the care bundle adherence is having a positive influence on the outcome.
