Catheter-Associated Urinary Tract Infections: Patient Characteristics, Treatment, And Clinical Outcomes In One South Texas Acute Care Hospital, Kimberly A. Ambrosini, Jose Campo Maldonado

MEDI 9331 Scholarly Activities Clinical Years

Background: Catheter-associated urinary tract infections (CA-UTIs) account for 40 percent of nosocomial infections worldwide. Their elimination is at the forefront of quality improvement in one South Texas acute care hospital.

Methods: Over a period of 6 months, five CA-UTIs occurred in one South Texas acute care hospital. These cases were identified via regular surveillance by Infection Prevention staff and the Laboratory Department of the hospital. This research reviews patient age, sex, length of stay, bacteria contracted, appropriate antibiotic use, patient characteristics, and overall outcomes.

Results: Between the months of July and December 2021, 5 CAUTIs were contracted. Patients …

Purple Urine Bag Syndrome: An Educational Case Of A Colorful Condition In The Chronically Catheterized, Teshome Gebrmichael, Fikirte Feleke, Waseem Ahmed, Madhulika Urella, Samson Teka

Samson Teka

Purple Urine Bag Syndrome is a rare condition characterized by purple discoloration of the urinary drainage bag. It is typically seen in elderly patients with chronic indwelling urinary catheterization, and is associated with urinary tract infections with high bacterial load, female gender, severe disability, constipation, and alkaline urine. This phenomenon occurs when tryptophan metabolites in the urine are broken down by bacteria containing indoxyl sulphatase and phosphatase enzymes. This results in the production of indigo and indirubin, which combine to give a purple appearance. This article presents a 78-year-old male with chronic urinary retention requiring intermittent Foley catheterization for the …

Some Observations On The Structure Of Encrusting Biofilms Of Proteus Mirabilis On Urethral Catheters, C. Winters, D. J. Stickler, N. S. Howe, T. J. Williams, N. Wilkinson, C. J. Buckley

Cells and Materials

A physical model of the bladder has been used to study the process of urinary catheter encrustation. Techniques have been devised for the preparation of sections through these encrustations in situ on the luminal surfaces of catheters and for mapping the distribution of calcium and magnesium in the biofilms. Transmission electron microscopy on these sections showed struvite-like crystals lying in the matrix and in direct contact with the catheter surface. Calcium phosphate ("bioapatite") was distributed throughout the film and many of these amorphous particles appear to have cells at their cores. Freeze-substituted sections of biofilms also showed electron dense materials …
