OBJECTIVES: To study the effects of comprehensive geriatric assessment (CGA) and multidisciplinary intervention on elderly patients sent home from the emergency department (ED). DESIGN: Prospective, randomized, controlled trial with 18 months of follow-up. SETTING: Large medical school-affiliated public hospital in an urban setting in Sydney, Australia. PARTICIPANTS: A total of 739 patients aged 75 and older discharged home from the ED were randomized into two groups. INTERVENTION: Patients randomized to the treatment group underwent initial CGA and were followed at home for up to 28 days by a hospital-based multidisciplinary outreach team. The team implemented or coordinated recommendations. The control group received usual care. MEASUREMENTS: The primary outcome measure was all admissions, to the hospital within 30 days of the initial ED visit. Secondary outcome measures were elective and emergency admissions, and nursing home admissions and mortality. Additional outcomes included physical function (Barthel Index (total possible score=20) and instrumental activities of daily living (/12) and cognitive function (mental status questionnaire (/10)). RESULTS: Intervention patients had a lower rate of all admissions to the hospital during the first 30 days after the initial ED visit (16.5% vs 22.2%; P=.048), a lower rate of emergency admissions during the 18-month follow-up (44.4% vs 54.3%; P=.007), and longer time to first emergency admission (382 vs 348 days; P=.011). There was no difference in admission to nursing homes or mortality. Patients randomized to the intervention group maintained a greater degree of physical and mental function (Barthel Index change from baseline at 6 months: -0.25 vs -0.75; P<.001; mental status questionnaire change from baseline at 12 months: -0.21 vs -0.64; P<.001). CONCLUSION: CGA and multidisciplinary intervention can improve health outcomes of older people at risk of deteriorating health and admission to hospital. Patients aged 75 and older should be referred for CGA after an ED visit.
STUDY OBJECTIVE: Elderly emergency department patients have complex medical needs and limited social support. A transitional model of care adapted from hospitals was tested for its effectiveness in the ED in reducing subsequent service use. METHODS: A randomized clinical trial was conducted at 2 urban, academically affiliated hospitals. Participants were 650 community-residing individuals 65 years or older who were discharged home after an ED visit. Main outcomes were service use rates, defined as repeat ED visits, hospitalizations, or nursing home admissions, and health care costs at 30 and 120 days. Intervention consisted of comprehensive geriatric assessment in the ED by an advanced practice nurse and subsequent referral to a community or social agency, primary care provider, and/or geriatric clinic for unmet health, social, and medical needs. Control group participants received usual and customary ED care. RESULTS: The intervention had no effect on overall service use rates at 30 or 120 days. However, the intervention was effective in lowering nursing home admissions at 30 days (0.7% versus 3%; odds ratio 0.21; 95% confidence interval [CI] 0.05 to 0.99) and in increasing patient satisfaction with ED discharge care (3.41 versus 3.03; mean difference 0.37; 95% CI 0.13 to 0.62). The intervention was more effective for high-risk than low-risk elders. CONCLUSION: An ED-based transitional model of care reduced subsequent nursing home admissions but did not decrease overall service use for older ED patients. Further studies are needed to determine the best models of care for this setting and for at-risk patients.
