Summary
Nosocomially acquired urinary tract infections (NAUTI) are common, with catheter-associated UTIs (CA-UTI) being more frequent. Characteristics and antimicrobial susceptibility were similar between CA-UTI and non-CA-UTI, even across general wards and ICUs.
Area of Science:
- Infectious Diseases
- Hospital Epidemiology
- Antimicrobial Resistance
Background:
- Nosocomially acquired urinary tract infections (NAUTI) are a significant public health concern.
- Understanding non-catheter-associated UTIs (non-CA-UTI) outside intensive care units (ICUs) is limited.
Purpose of the Study:
- To characterize patients with NAUTI, including etiology and antimicrobial susceptibility.
- To compare catheter-associated UTIs (CA-UTI) and non-CA-UTI in general wards and ICUs.
Main Methods:
- Retrospective, cross-sectional study conducted from 2009-2013 at a university hospital.
- Identified and classified 253 NAUTI episodes as CA-UTI or non-CA-UTI.
Main Results:
- CA-UTI (60.9%) was more frequent than non-CA-UTI.
- Escherichia coli, Klebsiella pneumoniae, and Enterococcus sp. were the most common pathogens.
- 19% of gram-negative bacilli produced extended-spectrum beta-lactamases, with no significant difference between groups.
Conclusions:
- Patient comorbidities, causative microorganisms, and antimicrobial susceptibility profiles were similar for CA-UTI and non-CA-UTI.
- These findings were consistent across both general wards and ICUs.

Urinary tract infections (UTIs) impact various parts of the urinary system, including the kidneys, ureters, bladder, and urethra. These infections are generally bacterial, with Escherichia coli being the most common causative agent, often originating from the gastrointestinal tract. However, other bacteria, such as Staphylococcus saprophyticus, Klebsiella pneumoniae, and Proteus mirabilis, are also known to cause UTIs. The type, location, and underlying complexity of the UTI guide both...

732
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...

In managing urinary tract infections (UTIs) in nursing, a comprehensive assessment is essential. Begin by gathering subjective data, such as the patient’s complaints of dysuria (painful urination), urinary frequency, urgency, suprapubic pain, and any lower abdominal discomfort. This information can be complemented by questions regarding previous UTIs, sexual activity, and personal hygiene practices, which can provide insight into risk factors. Objective assessment should focus on signs...

528
Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...
