Improving Quality of Emergency Care Through Integration of Mental Health

Hospital Capabilities Associated With Behavioral Health Integration Within Emergency Departments

OBJECTIVES

To identify hospital capabilities associated with behavioral health (BH) processes in emergency departments (EDs).

RESEARCH DESIGN

Six hundred two hospital responses to the 2017/2018 National Survey of Healthcare Organizations and Systems were linked to 2017 American Hospital Association Annual Survey data. Separate multivariable regressions estimated how hospital capabilities (the use of quality improvement methods, approaches to disseminate best patient-care practices, barriers to using care delivery innovations, and inpatient beds for psychiatric or substance use) were associated with each of 4 ED-based BH processes: mental health and substance use disorder screening, team-based approaches to BH, telepsychiatry, and direct referrals to community-based BH clinicians. Models controlled for hospital structural characteristics and area-level socioeconomic factors.

RESULTS

Most hospitals screened for BH conditions and provided direct referrals to community-based BH clinicians. Approximately half of the hospitals used a team approach to BH. A minority had implemented telepsychiatry. Each additional process used to disseminate best patient-care practices was associated with more screening for BH conditions (an increase of 4.07 points on the screening index, P <0.01) and greater likelihood of using a team approach to BH [4.41 percentage point ( P <0.01) increase]. Hospitals reporting more barriers to the use of care delivery innovations reported less screening and use of a team approach [a decrease of 0.15 points on the screening index ( P <0.01) and 0.28 percentage points reduction in likelihood of team approach use ( P <0.001) for 1-point increase in the barrier index].

CONCLUSIONS

Research and interventions focused on removing innovation barriers or adding processes to disseminate best practices offer a path to accelerate BH integration in hospital EDs.

Improving emergency department care for adults presenting with mental illness: a systematic review of strategies and their impact on outcomes, experience, and performance

Background

Care delivery for the increasing number of people presenting at hospital emergency departments (EDs) with mental illness is a challenging issue. This review aimed to synthesise the research evidence associated with strategies used to improve ED care delivery outcomes, experience, and performance for adults presenting with mental illness.

Method

We systematically reviewed the evidence regarding the effects of ED-based interventions for mental illness on patient outcomes, patient experience, and system performance, using a comprehensive search strategy designed to identify published empirical studies. Systematic searches in Scopus, Ovid Embase, CINAHL, and Medline were conducted in September 2023 (from inception; review protocol was prospectively registered in Prospero CRD42023466062). Eligibility criteria were as follows: (1) primary research study, published in English; and (2) (a) reported an implemented model of care or system change within the hospital ED context, (b) focused on adult mental illness presentations, and (c) evaluated system performance, patient outcomes, patient experience, or staff experience. Pairs of reviewers independently assessed study titles, abstracts, and full texts according to pre-established inclusion criteria with discrepancies resolved by a third reviewer. Independent reviewers extracted data from the included papers using Covidence (2023), and the quality of included studies was assessed using the Joanna Briggs Institute suite of critical appraisal tools.

Results

A narrative synthesis was performed on the included 46 studies, comprising pre-post (n = 23), quasi-experimental (n = 6), descriptive (n = 6), randomised controlled trial (RCT; n = 3), cohort (n = 2), cross-sectional (n = 2), qualitative (n = 2), realist evaluation (n = 1), and time series analysis studies (n = 1). Eleven articles focused on presentations related to substance use disorder presentation, 9 focused on suicide and deliberate self-harm presentations, and 26 reported mental illness presentations in general. Strategies reported include models of care (e.g., ED-initiated Medications for Opioid Use Disorder, ED-initiated social support, and deliberate self-harm), decision support tools, discharge and transfer refinements, case management, adjustments to liaison psychiatry services, telepsychiatry, changes to roles and rostering, environmental changes (e.g., specialised units within the ED), education, creation of multidisciplinary teams, and care standardisations. System performance measures were reported in 33 studies (72%), with fewer studies reporting measures of patient outcomes (n = 19, 41%), patient experience (n = 10, 22%), or staff experience (n = 14, 30%). Few interventions reported outcomes across all four domains. Heterogeneity in study samples, strategies, and evaluated outcomes makes adopting existing strategies challenging.

Conclusion

Care for mental illness is complex, particularly in the emergency setting. Strategies to provide care must align ED system goals with patient goals and staff experience.

Housing Status as a Predictor for Outpatient Care Following an Emergency or Urgent Care Encounter with a Behavioral Health Diagnosis: A Multivariable Analysis

Individuals without stable housing experience high rates of mental illness and seek behavioral health care in emergency care settings. Little is known about the effect of homelessness on outpatient follow-up after utilizing emergency or urgent care for behavioral health care. Patient encounters with behavioral health diagnoses among 7 emergency department (ED) or urgent care (UC) locations over 4 years were used to determine the correlation between housing status and outpatient follow-up within 90 days. Of 1,160,386 visits by 269,615 unique patients, 55,738 (23%) encounters included a behavioral health diagnosis. Patients with stable housing were twice as likely to follow up with a primary care provider (PCP) and with an outpatient behavioral health provider than patients without housing (aOR 2.60; aOR 2.00, p < 0.0001). Homelessness is associated with difficulty in accessing follow-up behavioral health care. UCs and EDs may use specific interventions to improve outpatient follow-up.

Predictors of hospital admission for patients presenting with psychiatric emergencies: A retrospective, cohort study

BACKGROUND

Rising psychiatric visits represent a significant and growing burden for emergency departments (EDs) across Canada. For individual psychiatric conditions, there are likely a variety of demographic and social variables that may increase risk of resource intensive hospital admission.

METHODS

We conducted a retrospective cohort study of all patients admitted into inpatient psychiatric units from two EDs in Kingston, Ontario, Canada from 2015 to 2018. We collected demographic and social variables from an electronic ED information system inclusive of all patients presenting to the ED with a mental health or addictions-related chief complaint. We used multivariate logistic regression models to identify predictors of psychiatric admission.

RESULTS

A total of 23,814 patients (49.1% male, median age 33) were identified. Admitted patients (n=1838) tended to be older (49 vs. 31 years), have lower Canadian Triage Acuity Scale scores (2.6 vs. 3.0), arrive by ambulance (51% vs. 35%) or police (18% vs. 9%), and have longer lengths of stay (8.4 vs. 4.9 hours). Individuals with mood and psychotic disorders were more likely to require a hospital admission.

CONCLUSION

A variety of clinical and demographic variables increased the risk of hospital admissions for individuals with a variety of psychiatric disorders.

The impact of different liaison psychiatry models on the emergency department: A systematic review of the international evidence

OBJECTIVE

This review aimed to evaluate the current evidence for what impact different Liaison Psychiatry (LP) services are having on Emergency Departments (ED). Mental Health (MH) problems contribute to 12 million annual US ED attendances and 5% in the UK.

METHODS

Databases were searched for articles describing LP services for adult MH patients attending EDs which reported ED care-related outcomes, published since 2000. Articles were screened and relevant articles quality assessed and narratively synthesized.

RESULTS

3653 articles were identified and 17 included in the review. Study designs were overall of poor-moderate quality, using retrospective before-and-after study designs. LP services were categorized into four models. Models with MH personnel integrated into the ED team or triage reduced patient waiting time to be seen, may reduce patients leaving without being seen and have high staff satisfaction. Co-located MH space or personnel reduced patient waiting times. Care agreements with existing psychiatry teams don't affect waiting times or ED length of stay. Transferring patients to external services reduces patients' time in the ED. There is insufficient evidence about patient satisfaction, costs, and onward care.

CONCLUSIONS

Waiting times are shortened by MH personnel integrated into the ED and are more satisfactory to staff than other LP models. The involvement of a psychiatrist in the LP team improves the care quality. All models may improve safety for patients but most evaluations are of poor quality and therefore there is still insufficient evidence to recommend one service model over another and further robust research is required.
