Optimizing emergency department care transitions to outpatient settings: A systematic review and meta-analysis

Emergency Department-to-Community Transitions of Care: Best Practices for the Older Adult Population

This article describes emergency department (ED)-to-community care transitions for older adults and associated challenges, measurement, proven efficacious and effective interventions, and policy considerations. Older adults experiencing social isolation and impairments in functional status or cognition represent unique populations that are particularly at risk during ED-to-community transitions of care and may benefit from targeted intervention implementation. Future efforts should target optimizing screening techniques to identify those at risk, developing and validating patient-centered outcome measures, and using policy and reimbursement levers to include transitional care management services for older adults within the ED setting.

Differential Effects of an Emergency Department-to-Home Care Transitions Intervention in an Older Adult Population: A Latent Class Analysis

BACKGROUND

Older adults frequently return to the emergency department (ED) within 30 days of a visit. High-risk patients can differentially benefit from transitional care interventions. Latent class analysis (LCA) is a model-based method used to segment the population and test intervention effects by subgroup.

OBJECTIVES

We aimed to identify latent classes within an older adult population from a randomized controlled trial evaluating the effectiveness of an ED-to-home transitional care program and test whether class membership modified the intervention effect.

RESEARCH DESIGN

Participants were randomized to receive the Care Transitions Intervention or usual care. Study staff collected outcomes data through medical record reviews and surveys. We performed LCA and logistic regression to evaluate the differential effects of the intervention by class membership.

SUBJECTS

Participants were ED patients (age 60 y and above) discharged to a community residence.

MEASURES

Indicator variables for the LCA included clinically available and patient-reported data from the initial ED visit. Our primary outcome was ED revisits within 30 days. Secondary outcomes included ED revisits within 14 days, outpatient follow-up within 7 and 30 days, and self-management behaviors.

RESULTS

We interpreted 6 latent classes in this study population. Classes 1, 4, 5, and 6 showed a reduction in ED revisit rates with the intervention; classes 2 and 3 showed an increase in ED revisit rates. In class 5, we found evidence that the intervention increased outpatient follow-up within 7 and 30 days (odds ratio: 1.81, 95% CI: 1.13-2.91; odds ratio: 2.24, 95% CI: 1.25-4.03).

CONCLUSIONS

Class membership modified the intervention effect. Population segmentation is an important step in evaluating a transitional care intervention.

Effect of ED-based transitional care interventions by healthcare professionals providing transitional care in the emergency department on clinical, process and service use outcomes: a systematic review

OBJECTIVE

Suboptimal transitional care (ie, needs assessment and coordination of follow-up care) in the emergency department (ED) is an important cause of ED revisits and hospital admissions and may potentially harm patients, especially frail older adults. We aimed to systematically review the effect of ED-based interventions by health professionals who are dedicated to providing transitional care to older adults.

DESIGN

Systematic review.

MEASUREMENTS

We searched five biomedical databases for published (quasi)experimental studies evaluating the effects of health professionals in the ED dedicated to providing transitional care to older ED patients on clinical, process and/or service use outcomes. Reviewers screened studies for relevance and assessed methodological quality with published criteria (Robins-1 and the Cochrane risk of bias tool). Data were synthesised around study and intervention characteristics and outcomes of interest.

RESULTS

From the 6561 references initially extracted from the databases, 12 studies were eligible for inclusion. Two types of interventions were identified, namely, individual needs assessment of ED patients (8 studies; 75%) and discharge planning and coordination of services (4 studies; 25%). Structured individual needs assessment was associated with a significant decrease in hospital admissions, hospital readmissions and ED revisits. Individualised discharge plans from the ED were associated with a significant decrease in ED revisits and hospital readmission. The overall methodological quality of the included studies was relatively low.

CONCLUSIONS

Comprehensive assessment of patient needs and ED discharge planning and coordination of services by health professionals interested in transitional care can help optimise the transition of care for older ED patients and reduce the risk of costly and potentially harmful (re)admissions for this population. However, more robust research is needed on the effectiveness of these interventions aiming to improve clinical, process and service use outcomes.

Patient experiences of a care transition intervention for Veterans to reduce emergency department visits

OBJECTIVES

Care transition interventions (CTIs) are used to improve outcomes after an emergency department (ED) visit. A recent randomized controlled trial of a Veterans Health Administration (VHA) CTI titled Discharge Information and Support for Patients receiving Outpatient care in the ED (DISPO ED) demonstrated no difference in repeat ED visits. However, changes in health care utilization are not the only measures of a CTI worth evaluation, and there is interest in using patient-centered outcomes to assess CTIs as well. To inform future CTI design and outcome measure selection, the study aims were to understand how patients experienced the CTI and what elements they valued.

METHODS

This was a qualitative study of participants randomized to the intervention arm of the DISPO ED trial using semistructured interviews. The interview guide included questions about clinical health and other issues addressed by the study nurse, the most and least helpful aspects of the intervention, and impacts of the intervention on their perceptions of self-management. Interviews were analyzed using directed content analysis.

RESULTS

Our sample comprised 24 participants, with average age of 61 years, 58% male, and 50% Black or African American. We identified six major themes related to (1) experiences during the intervention and (2) elements they valued. Patients reported clinical health coaching recommendations covering a wide range of topics as well as care coordination actions such as appointment scheduling. Valuable elements of the intervention highlighted personal characteristics of the study nurse that promoted a sense of interpersonal connection and empathy in their interactions.

CONCLUSIONS

Intervention users described assistance with care coordination as well as clinical concerns. We identified aspects that were highly valued by the participants, such as interpersonal support and empathy from the interventionist. These findings suggest the need for more comprehensive nonutilization outcome measures for CTIs to capture the patient's perspective.

Value-based analysis of a Singaporean post-ED discharge support program for older adults

Objective

We evaluated the effectiveness of a post emergency department (ED) discharge intervention for frail, older adult patients in reducing hospital admissions.

Methods

9-month retrospective real-world evaluation of a quality improvement intervention comparing frail adults 65-years and older who received a post-ED discharge intervention program (SAFE-Lite) with those who were eligible but declined and received usual care instead. The primary outcomes were the differences in rates of first acute hospital admission at 30- and 60-days post-ED discharge. The difference in primary outcome between the two groups was compared using the Cox proportional hazards model. We report adjusted hazards ratios (HRs) with 95% CIs for age, gender, Triage Risk Screening Tool (TRST) scores, as well as baseline ED utilization and acute hospital admission rates in the past year.

Results

There were 66 patients in the intervention group and 46 patients in the control group. There was no significant difference in risk of acute hospital admission at both 30 days (15 vs. 13%, HR = 0.92, 95% CI: 0.35–2.41) and 60 days (21 vs. 16%, HR = 0.97, 95% CI: 0.42–2.21) for the intervention and control groups.

Conclusion

Compared to usual post-ED discharge care, SAFE-Lite showed no difference in reducing 30- and 60-day admissions of frail, older patients.

Effectiveness of a care transitions intervention for older adults discharged home from the emergency department: A randomized controlled trial

BACKGROUND

Improving care transitions following emergency department (ED) visits may reduce post-ED adverse events among older adults (e.g., ED revisits, decreased function). The Care Transitions Intervention (CTI) improves hospital-to-home transitions; however, its effectiveness at improving post-ED outcomes is unknown. We tested the effectiveness of the CTI with community-dwelling older adult ED patients, hypothesizing that it would reduce revisits and increase performance of self-management behaviors during the 30 days following discharge.

METHODS

We conducted a randomized controlled trial among patients age ≥ 60 discharged home from one of three EDs in two states. Intervention participants received a minimally modified CTI, with a home visit 24 to 72 h postdischarge and one to three phone calls over 28 days. We collected demographic, health status, and psychosocial data at the initial ED visit. Medication adherence and knowledge of red flag symptoms were assessed via phone survey. Care use and comorbidities were abstracted from medical records. We performed multivariate regressions for intention-to-treat and per-protocol (PP) analyses.

RESULTS

Participant characteristics (N = 1,756) were similar across groups: mean age 72.4 ± 8.6 years and 53% female. Of those randomized to the intervention, 84% completed the home visit. Overall, 12.4% of participants returned to the ED within 30 days. The CTI did not significantly affect odds of 30-day ED revisits (adjusted odds ratio [AOR] = 0.97, 95% confidence interval [CI] = 0.72 to 1.30) or medication adherence (AOR = 0.89, 95% CI = 0.60 to 1.32). Participants receiving the CTI (PP) had increased odds of in-person follow-up with outpatient clinicians during the week following discharge (AOR = 1.24, 95% CI = 1.01 to 1.51) and recalling at least one red flag from ED discharge instructions (AOR = 1.34 95% CI = 1.05 to 1.71).

CONCLUSIONS

The CTI did not reduce 30-day ED revisits but did significantly increase key care transition behaviors (outpatient follow-up, red flag knowledge). Additional research is needed to explore if patients with different conditions benefit more from the CTI and whether decreasing ED revisits is the most appropriate outcome for all older adults.

Exploring differential response to an emergency department-based care transition intervention

OBJECTIVE

To identify multivariable subgroups of patients with differential responses to a nurse-delivered care transition intervention after an emergency department (ED) visit in a randomized controlled trial (RCT) using an emerging data-driven method.

DESIGN

Secondary analysis of RCT.

PARTICIPANTS

512 individuals enrolled in an RCT of a nurse-delivered care transition intervention after an ED visit. All 512 participants were included in a pre-specified subgroup analysis, and 451 of these had sufficient complete case data to be included in a model-based recursive (MoB) partitioning analysis.

METHODS

The primary outcome was having at least one ED visit in 30 days after the index ED visit. Two analytical methods explored heterogeneity of treatment effects: data driven model-based recursive partitioning (MoB) using 37 candidate baseline variables, and a contextual point of comparison with prespecified subgroups defined by ED super-user status (≥ 3 ED visits in previous 6 months or not), sex (male/female), and age, individually examined via treatment arm by subgroup interaction terms in logistic regression models. Internal validation of the MoB analysis via bootstrap resampling with an optimism corrected c-statistic was conducted to provide a bias-corrected estimate.

RESULTS

MoB detected treatment effect heterogeneity in a single subgroup, marital status. Unmarried patients randomized to the intervention had a repeat ED use rate of 22% compared to 34% in the usual care group; married patients randomized to the intervention had a 27% ED return rate compared to 12% in the usual care group. Internal validation demonstrated an optimism corrected c-statistic of 0.54. No treatment-by-covariate subgroup interactions were identified among the 3 prespecified subgroups.

CONCLUSION

Although exploratory, the results of the MoB analysis suggest that patient factors related to social relationships such as marital status may be important contributors to differential response to a care transition intervention after an ED visit. These were characteristics that the investigators had not anticipated or planned to examine in the individual prespecified subgroup analysis. Data-driven methods can yield unexpected findings and contribute to a more complete understanding of differential treatment effects in subgroup analysis, which can inform further work on development of effective care transition interventions in the ED setting.

Care transitions and social needs: A Geriatric Emergency care Applied Research (GEAR) Network scoping review and consensus statement

OBJECTIVES

Individual-level social needs have been shown to substantially impact emergency department (ED) care transitions of older adults. The Geriatric Emergency care Applied Research (GEAR) Network aimed to identify care transition interventions, particularly addressing social needs, and prioritize future research questions.

METHODS

GEAR engaged 49 interdisciplinary stakeholders, derived clinical questions, and conducted searches of electronic databases to identify ED discharge care transition interventions in older adult populations. Informed by the Protocol for Responding to and Assessing Patients' Assets, Risks, and Experiences (PRAPARE) framework, data extraction and synthesis of included studies included the degree that intervention components addressed social needs and their association with patient outcomes. GEAR convened a consensus conference to identify topics of highest priority for future care transitions research.

RESULTS

Our search identified 248 unique articles addressing care transition interventions in older adult populations. Of these, 17 individual care transition intervention studies were included in the current literature synthesis. Overall, common care transition interventions included coordination efforts, comprehensive geriatric assessments, discharge planning, and telephone or in-person follow-up. Fourteen of the 17 care transition intervention studies in older adults specifically addressed at least one social need within the PRAPARE framework, most commonly related to access to food, medicine, or health care. No care transition intervention addressing social needs in older adult populations consistently reduced subsequent health care utilization or other patient-centered outcomes. GEAR stakeholders identified that determining optimal outcome measures for ED-home transition interventions was the highest priority area for future care transitions research.

CONCLUSIONS

ED care transition intervention studies in older adults frequently address at least one social need component and exhibit variation in the degree of success on a wide array of health care utilization outcomes.
