OBJECTIVES: To determine the relationship between the reason for an emergency department (ED) visit and subsequent risk of adverse health outcomes in older adults discharged from the ED. DESIGN: Secondary analysis of data from the Medicare Current Beneficiary Survey. SETTING: ED. PARTICIPANTS: One thousand eight hundred fifty-one community-dwelling Medicare fee-for-service enrollees aged 65 and older discharged from the ED between January 2000 and September 2002. MEASUREMENTS: Independent variables were ED discharge diagnosis groups: injury or musculoskeletal (MSK) (e.g., fracture, open wound), chronic condition (e.g., chronic obstructive pulmonary disorder, heart failure), infection, non-MSK symptom (e.g., chest pain, abdominal pain), and unclassified. Adverse health outcomes were hospitalization or death within 30 days of the index ED visit. RESULTS: Injury or MSK was the largest ED diagnosis group (31.4%), followed by non-MSK symptom (22.2%), chronic condition (20.9%), and infection (7.8%); 338 (17.8%) had ED discharge diagnoses that were unclassified. In adjusted analyses, a discharge diagnosis of injury or MSK condition was associated with lower risk of subsequent adverse health outcomes (hazard ratio (HR)=0.69, 95% confidence interval (CI)=0.50–0.96) than for all other diagnosis groups. Patients seen in the ED for chronic conditions were at greater risk of adverse outcomes (HR=1.86, 95% CI=1.37–2.52) than all others. There were no significant differences in risk between patients with infections, those with non-MSK symptoms, and the unclassified group. CONCLUSION: Adverse health outcomes were common in older patients with an ED discharge diagnosis classified as a chronic condition. ED discharge diagnosis may improve risk assessment and inform the development of targeted interventions to reduce adverse health outcomes in older adults discharged from the ED.

OBJECTIVES: To determine whether frail older adults, based on a deficit accumulation index (DAI), are at greater risk of adverse outcomes after discharge from the emergency department (ED). DESIGN AND SETTING: Secondary analysis of data from the Medicare Current Beneficiary Survey. PARTICIPANTS: One thousand eight hundred fifty-one community-dwelling Medicare fee-for-service enrollees, aged 65 and older who were discharged from the ED between January 2000 and September 2002. MEASUREMENTS: The primary dependent variable was time to first adverse outcome, defined as repeat outpatient ED visit, hospital admission, nursing home admission, or death, within 30 days of the index ED visit. RESULTS: Time to first adverse outcome was shortest in individuals with the highest number of accumulated deficits. The frailest participants were at greater risk of adverse outcomes after ED discharge than those who were least frail (hazard ratio (HR)=1.44, 95% confidence interval (CI)=1.06–1.96). The frailest individuals were also at higher risk of serious adverse outcomes, defined as hospitalization, nursing home admission, or death (HR=1.98, 95% CI=1.29–3.05). In contrast, no association was detected between degree of frailty and repeat outpatient ED visits within 30 days (HR=1.06, 95% CI=0.73–1.54). CONCLUSION: The DAI as a construct of frailty was a robust predictor of serious adverse outcomes in the first 30 days after ED discharge. Frailty was not found to be a major determinant of repeat outpatient ED visits; therefore, additional study is needed to investigate this particular type of health service use by older adults.

Background: An Emergency Department (ED) visit represents a time of significant risk for an older adult; however, little is known about adverse outcomes after an ED visit in the VA system.Objectives: 1) To describe the frequency and type of adverse health outcomes among older veterans discharged from the ED, and 2) To determine risk factors associated with adverse outcomes.Design: Retrospective, cohort study at an academically affiliated VA medical center.Patients: A total of 942 veterans > or = 65 years old discharged from the ED.Measurements and Main Results: Primary dependent variable was adverse outcome, defined as a repeat VA ED visit, hospitalization, and/or death within 90 days. Overall, 320 (34.0%) patients experienced an adverse outcome: 245 (26%) returned to the VA ED but were not admitted, 125 (13.3%) were hospitalized, and 23 (2.4%) died. In adjusted analyses, higher score on the Charlson Comorbidity Index (hazard ratio [HR] 1.11; 95% CI 1.03, 1.21), ED visit within the previous 6 months (HR 1.64; 95% CI 1.30, 2.06), hospitalization within the previous 6 months (HR 1.70, 95% CI 1.30, 2.22), and triage to the emergency unit (compared to urgent care clinic) (HR 1.76, 95% CI 1.32, 2.36) were independently associated with higher risk of adverse outcomes.Conclusion: More than 1 in 3 older veterans discharged from the ED experienced a significant adverse outcome within 90 days of ED discharge. Identifying veterans at greatest risk for adverse outcomes after ED discharge can inform the design and targeting of interventions to reduce morbidity and costs in this group. [ABSTRACT FROM AUTHOR]
