Patient Uncertainty as a Predictor of 30-day Return Emergency Department Visits: An Observational Study.

OBJECTIVE: The objective was to examine the relationship between patient uncertainty at the time of emergency department (ED) discharge as measured by the "Uncertainty Scale" (U-Scale) and 30-day return ED visits. We hypothesized that a higher score on the U-Scale predicts a higher likelihood of a 30-day return ED visit. METHODS: This was a cross-sectional single-site pilot study performed with adult patients discharged from an urban academic ED to assess the relationship of U-Scale total and subscale scores with 30-day return ED visits. We collected demographic and U-Scale scores at the time of ED discharge and subsequent 30-day ED utilization data by follow-up telephone call. RESULTS: No association was found between the total U-Scale score and subsequent ED utilization. Patients with higher uncertainty on the Treatment Quality subscale of the U-Scale had higher odds of a 30-day return ED visit (adjusted odds ratio [AOR] = 1.16), while patients with lower uncertainty on the Decision to Seek Care subscale had higher odds of a 30-day return ED visit (AOR = 0.68). CONCLUSION: Patient uncertainty as measured by the U-Scale total score was not predictive of subsequent ED utilization. However, uncertainty related to treatment quality and the decision to seek care as measured by the U-Scale subscales may be important in predicting repeat ED utilization. Unlike individual patient factors such as age and race that have been associated with frequent ED visits in prior studies, these domains of uncertainty are potentially modifiable. Providers and health systems may successfully prevent recurrent acute care encounters through implementation of interventions designed to address patient uncertainty. Further work is needed to refine the U-Scale and test its predictive utility among a larger patient cohort.

A Multidisciplinary Approach to Impact Acute Care Utilization in Sickle Cell Disease.

Sickle cell disease (SCD), an inherited red blood cell disorder, is characterized by anemia, end-organ damage, unpredictable episodes of pain, and early mortality. Emergency department (ED) visits and hospitalizations are frequent, leading to increased burden on patients and increased health care costs. This study assessed the effects of a multidisciplinary care team intervention on acute care utilization among adults with SCD. The multidisciplinary care team intervention included monthly team meetings and development of individualized care plans. Individualized care plans included targeted pain management plans for management of uncomplicated pain crisis. Following implementation of the multidisciplinary care team intervention, a significant decrease in ED utilization was identified among those individuals with a history of high ED utilization. Findings highlight the potential strength of multidisciplinary interventions and suggest that targeting interventions toward high-utilizing subpopulations may offer the greatest impact.

Geography, Not Health System Affiliations, Determines Patients' Revisits to the Emergency Department.

OBJECTIVES: To determine how frequently patients revisit the emergency department after an initial encounter, and to describe revisit capture rates for the same hospital, health system, and geographic region. DATA SOURCES/STUDY SETTING: Florida state data from January 1, 2010, to June 30, 2011, from the Healthcare Cost and Utilization Project. STUDY DESIGN: This is a retrospective cohort study of emergency department return visits among Florida adults over an 18-month period. We evaluated pairs of index and 30-day return emergency department visits and compared capture rates for hospital, health system, and geographic units. DATA COLLECTION/EXTRACTION METHODS: Data were obtained from the Agency for Healthcare Research and Quality's Healthcare Cost and Utilization Project and the American Hospital Association Annual Survey Database. PRINCIPAL FINDINGS: Among 9,416,212 emergency department visits, 22.6 percent (2,124,441) were associated with a 30-day return. Seventy percent (1,477,772) of 30-day returns occurred to the same hospital. The 30-day return capture rates were highest within the same geographic area: county-level capture at 92 percent (IQR=86-96 percent) versus health system capture at 75 percent (IQR = 68-81 percent). CONCLUSIONS: Acute care utilization patterns are often independent of health system boundaries. Current population-based health care models that attribute patients to a single provider or health system may be strengthened by considering geographic patterns of acute care utilization.
