The purpose of this study is to see if the investigators can identify early those patients who are admitted to the hospital and have a urinary tract infection (UTI) or those patients that develop a UTI during their hospitalization.

Primary Outcome Measures:
  • Identify of bacteria, genes and proteins that are highly predictive of UTI development [ Time Frame: Nine months ] [ Designated as safety issue: No ]
    To identify which bacteria, genes and proteins will be highly predictive of UTI development in geriatric trauma patients. We hypothesize that the combination of 16S rDNA and metaproteomics will identify the most informative biosignatures (species/genes/proteins) discerning UTI from asymptomatic bacteriuria.

Secondary Outcome Measures:
  • Biomarker candidates for UTIs recalcitrant to antibiotic treatment. [ Time Frame: Nine months ] [ Designated as safety issue: No ]
  • Morbidity [ Time Frame: 9 months ] [ Designated as safety issue: No ]
  • Mortality [ Time Frame: 9 months ] [ Designated as safety issue: Yes ]

Biospecimen Retention:   Samples With DNA
