Community acquired urinary tract infections in older adults
Abstract
Background Community acquired urinary tract infections (caUTI) in adults are common ailments. Older adults are prone to infectious diseases, diagnosis can be difficult, their etiologic and antimicrobial resistance are poorly known. Objectives To evaluate the incidence discriminated by sex, symptoms, and to determine pathogens and their antimicrobial resistance rate. Methods A retrospective, descriptive and comparative study. We analyze uricultures among 2013 in the Hospital Nacional de Clinicas (Córdoba-Argentina). Patients over 65 years old, admitted with a caUTI diagnose were included; we exclude those with urinary catheter. Variables used: Sex, symptoms, pathogen isolation, antimicrobial resistance. For symptom variable was performed a comparative test. Descriptive statistics were used to analyze remaining variables. Results Were analyzed 349 patients: 1) Positive uricultures 191 (case), negative 158 (control). 2) Average age 77 (76% women, 24% men). 3) Symptoms: fever (45%), sepsis criteria (17%), altered mental status (14%), heart failure (11%). 4) Uriculture: monomicrobial 95.29%. 5) Isolation and resistance rate: Escherichia coli (67,7%): ampicillin/sulbactam 52.7%, ciprofloxacin 51.9%, trimethoprim/sulfamethoxazole 45.7%, cefotaxime: 12,9 %, amikacin: 3,9 %, Klebsiella pneumoniae (11,97%): ciprofloxacin 60.8%, trimethoprim/ sulfamethoxazole 50%, cefotaxime 47.8%, amikacin 4.7%. Enterococcus spp. (9,89%): ampicillin 0%, vancomycin 0%. Also isolated: Cándida spp.…
How strong is the evidence?
Evidence Hub reads this as a case-control, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 349 participants or records.
