Office Management of Genitourinary and Gastrointestinal Procedures

Insertion of urinary catheters (most often Foley catheters) can be performed in outpatient settings to manage acute urinary obstruction without referral to emergency services, as well as to obtain urine samples in patients not able to provide a clean catch urine sample. For patients with established suprapubic urinary catheters, routine exchange can also occur safely in primary care settings. Excision of a thrombosed external hemorrhoid can be performed in the office setting with local anesthesia. The procedure offers better clinical outcomes than symptomatic treatment if performed within the first 72 hours from the onset of symptoms.

Guidelines for Infection Control in the Urological Field, including Urinary Tract Management (revised second edition)

The Committee for the Development of Guidelines for Infection Control in the Urological Field, including Urinary Tract Management of the Japanese Urological Association, together with its systematic review team and external reviewers, have prepared a set of practice guidelines, an abridged version of which is published herein. These guidelines cover the following topics: (i) foundations of infection control, standard precautions, route-specific precautions, and occupational infection control (including vaccines); (ii) the relationship between urologists and infection control; (iii) infection control in urological wards and outpatient clinics; (iv) response to hepatitis B virus reactivation; (v) infection control in urological procedures and examinations; (vi) prevention of infections occurring in conjunction with medical procedures and examinations; (vii) responses to urinary tract tuberculosis and bacillus Calmette-Guérin; (viii) aseptic handling, cleaning, disinfection, and sterilization of urinary tract endoscopes (principles of endoscope manipulation, endoscope lumen cleaning, and disinfection); (ix) infection control in the operating room (principles of hand washing, preoperative rubbing methods, etc.); (x) prevention of needlestick and blood/bodily fluid exposure and response to accidental exposure; (xi) urinary catheter-associated urinary tract infection and purple urinary bag syndrome; and (xii) urinary catheter-associated urinary tract infections in conjunction with home care. In addressing these topics, the relevant medical literature was searched to the extent possible, and content was prepared for the purpose of providing useful information for clinical practice.

Spinal Cord Injury Creates Unique Challenges in Diagnosis and Management of Catheter-Associated Urinary Tract Infection

Background: Catheter-associated urinary tract infection (CAUTI) is associated with increased morbidity and mortality and influences the quality of life of patients with spinal cord injury (SCI). Objectives: This clinical review aims to highlight the unique surveillance, prevention, diagnosis, and management challenges of CAUTI in the SCI population. Methods: Narrative review of the current literature on catheter use in persons with SCI was conducted to determine gaps in knowledge and opportunities for improvement. Results: Surveillance of CAUTI is challenging in the SCI population as the ability to detect symptoms used to diagnose CAUTI (ie, suprapubic pain, dysuria) is impaired. In terms of prevention of CAUTI, current strategies refocus on appropriate catheter insertion and care and early removal of catheters, which is not always feasible for persons with SCI. Prophylactic antibiotics, nutraceuticals, and coated catheters show limited efficacy in infection prevention. Diagnosing CAUTI after SCI is challenging, often resulting in an overdiagnosis of CAUTI when truly asymptomatic bacteriuria exists. In the management of CAUTI in patients with SCI, the use of multiple antibiotics over time in an individual increases the rate of multidrug-resistant organisms; therefore, the exploration of novel non-antibiotic treatments is of importance. The patient experience should be at the center of all these efforts. Conclusion: Better diagnostic tools or biomarkers are needed to define true CAUTI in people with SCI. SCI-specific evidence to inform catheter management and CAUTI treatment guidelines is needed, with the goal to minimize catheter-related harm, reduce antibiotic resistance, and improve satisfaction and overall quality of life for SCI patients.

Factors associated with specific uropathogens in catheter-associated urinary tract infection: Developing a clinical prediction model

Objectives

To identify characteristics associated with particular groups of uropathogens in catheter-associated urinary tract infection (CA–UTI) and to develop clinical prediction rules for identifying these groups.

Methods

Demographic, clinical and microbiological data were analysed from patients with CA–UTI. Infections were categorized into enteric Gram-negative rods, nonfermenters, Gram-positive cocci and fungal. Variables were analysed using univariate and multiple logistic regression analyses, and were used to develop clinical prediction rules.

Results

A total of 492 patients were included in the study. Candida species were the most common uropathogens (30.7%), followed by enterococci (17.3%), Escherichia coli (12.0%), Pseudomonas spp. (10.8%), Klebsiella spp. (7.9%) and staphylococci (6.5%). Clinical prediction rules for the bacterial uropathogenic groups showed poor-to-fair discriminatory power, with sensitivities of <40% and specificities of >90%. However, clinical prediction rules showed good discriminatory power for fungal infections, with a sensitivity of 67.3% and a specificity of 78.1%.

Conclusions

Clinical prediction rules developed for identifying specific groups of bacterial uropathogens in patients with CA–UTI had a low sensitivity, whereas those for fungal infections showed good discriminatory power. Further studies to develop more refined and sensitive tools for predicting specific bacterial uropathogens in CA–UTI are warranted.
