Predictors of Older Adult Adherence With Emergency Department Discharge Instructions.

OBJECTIVE: Older adults discharged from the emergency department (ED) are at high risk for adverse outcomes. Adherence to ED discharge instructions is necessary to reduce those risks. The objective of this study is to determine the individual-level factors associated with adherence with ED discharge instructions among older adult ED outpatients. METHODS: We performed a secondary analysis of data from the control group of a randomized controlled trial testing a care transitions intervention among older adults (age ≥ 60 years) discharged home from the ED in two states. Taking data from patient surveys and chart reviews, we used multivariable logistic regression to identify patient characteristics associated with adherence to printed discharge instructions. Outcomes were patient-reported medication adherence, provider follow-up visit adherence, and knowledge of "red flags" (signs of worsening health requiring further medical attention). RESULTS: A total 824 patients were potentially eligible, and 699 had data in at least one pillar. A total of 35% adhered to medication instructions, 76% adhered to follow-up instructions, and 35% recalled at least one red flag. In the multivariate analysis, no factors were significantly associated with failure to adhere to medications. Participants with poor health status (adjusted odds ratio [AOR] = 0.55, 95% confidence interval [CI] = 0.31 to 0.98) were less likely to adhere to follow-up instructions. Participants who were older (AORs trended downward as age category increased) or depressed (AOR = 0.39, 95% CI = 0.17 to 0.85) or had one or more functional limitations (AOR = 0.62, 95% CI = 0.41 to 0.94) were less likely to recall red flags. CONCLUSION: Older adults discharged home from the ED have mixed rates of adherence to discharge instructions. Although it is thought that some subgroups may be higher risk than others, given the opportunity to improve ED-to-home transitions, EDs and health systems should consider providing additional care transition support to all older adults discharged home from the ED.

Association between social isolation and outpatient follow-up in older adults following emergency department discharge.

OBJECTIVES: Follow-up with outpatient clinicians after discharge from the emergency department (ED) reduces adverse outcomes among older adults, but rates are suboptimal. Social isolation, a common factor associated with poor health outcomes, may help explain these low rates. This study evaluates social isolation as a predictor of outpatient follow-up after discharge from the ED. MATERIALS AND METHODS: This cohort study uses the control group from a randomized-controlled trial investigating a community paramedic-delivered Care Transitions Intervention with older patients (age≥60 years) at three EDs in mid-sized cities. Social Isolation scores were measured at baseline using the PROMIS 4-item social isolation questionnaire, grouped into tertiles for analysis. Chart abstraction was conducted to identify follow-up with outpatient primary or specialty healthcare providers and method of contact within 7 and 30 days of discharge. RESULTS: Of 642 patients, highly socially-isolated adults reported significantly worse overall health, as well as increased anxiety, depressive symptoms, functional limitations, and co-morbid conditions compared to those less socially-isolated (p<0.01). We found no effect of social isolation on 30-day follow-up. Patients with high social isolation, however, were 37% less likely to follow-up with a provider in-person within 7 days of ED discharge compared to low social isolation (OR:0.63, 95% CI:0.42-0.96). CONCLUSION: This study adds to our understanding of how and when socially-isolated older adults seek outpatient care following ED discharge. Increased social isolation was not significantly associated with all-contact follow-up rates after ED discharge. However, patients reporting higher social isolation had lower rates of in-person follow-up in the week following ED discharge.
