Reducing health care-associated urinary tract infection (UTI) is a National Patient Safety Goal. The purpose of this investigation was to establish a colony count threshold to predict clinically significant UTIs that develop in hospitalized patients. A total of 185 cases were reviewed sequentially by 2 physicians. The information extracted included subjective complaints, presence of an indwelling urinary catheter, clinical signs and symptoms, WBC count, urinalysis, and urine culture results. The first reviewer recorded whether the patient was diagnosed and treated for a UTI by the clinician. The second reviewer determined if the patient met National Healthcare Safety Network guidelines for nosocomial UTI. Compared with patients with colony counts less than 100,000 colony-forming units per milliliter (CFU/mL), patients with colony counts 100,000 CFU/mL or more were 73.86 times more likely to have a clinically significant UTI (odds ratio, 73.86; 95% confidence interval, 24.23 ∼ 225.15; P < .0001; c-statistic, 0.859). Reporting positive results only for patients with 100,000 CFU/mL or more would have reduced the number of positive cultures by 38%. These data suggest that reporting colony counts less than 100,000 CFU/mL encourages treatment of non-clinically significant UTIs in hospitalized patients, causing inappropriate antibiotic use.
Students with sensory and physical disabilities are underrepresented in medical schools despite the availability of assistive technologies and accommodations. Unfortunately, many medical schools have adopted restrictive "organic" technical standards based on deficits rather than on the ability to do the work. Compelling ethical considerations of justice and beneficence should prompt change in this arena. Medical schools should instead embrace "functional" technical standards that permit accommodations for disabilities and update their admissions policies to promote applications from qualified students with disabilities. Medical schools thus should focus on what students with disabilities can do, rather than what they cannot do, because these students further diversify the health care profession and improve our ability to care for an expanding population of patients with disabilities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
