Rising KL, et al. - Researchers performed this cross-sectional, single-site, pilot study of adult patients discharged from an urban academic emergency department (ED) to determine the relationship between patient uncertainty at the time of ED discharge as measured by the “Uncertainty Scale” (U-Scale) and 30-day return ED visits. The authors did not observe any association of total U-Scale score with subsequent ED utilization. Higher odds of a 30-day return ED visit were evident among patients with higher uncertainty on the Treatment Quality subscale of the U-Scale and among patients with lower uncertainty on the Decision to Seek Care subscale.
