The transformation of crisis care and liaison mental health services has become a pivotal focus for mental health systems, particularly in response to the challenges posed by the COVID-19 pandemic and the increasing demand for accessible, timely, and effective mental health support. Across the United Kingdom, initiatives have been implemented to shift care from inpatient settings toward community-based models, emphasizing early intervention, emergency department (ED) diversion, and integrated crisis response teams. This article explores the evolution of these services, including the development of off-site mental health crisis assessment units, enhanced liaison psychiatry roles, and the integration of mental health professionals into emergency and community care systems. The focus is on how these transformations aim to improve outcomes for individuals experiencing mental health crises, particularly children, young people, and those with learning disabilities or autism.
Crisis Care and Liaison Mental Health Services in Response to the Pandemic
The emergence of the COVID-19 pandemic in early 2020 significantly disrupted mental health services, leading to a sharp decline in referrals to liaison psychiatry services across the North Central London care sector. Between January 2020 and September 2020, total referrals decreased by 16.5%, with both emergency department (ED) and ward referrals experiencing similar reductions. A marked drop was observed during the first wave of the pandemic (March and April 2020), reflecting the impact of lockdowns and restrictions on access to routine mental health care. As lockdown measures eased, referral rates began to increase again, indicating the ongoing demand for mental health services and the need for sustainable adaptations.
In response to these challenges, new service models were rapidly implemented, including the establishment of off-site mental health crisis assessment services. One notable example is the Mental Health Crisis Assessment Service (MHCAS), introduced by Camden and Islington NHS Foundation Trust. This service was designed to divert individuals from ED departments by offering clinical assessments in a dedicated, non-hospital environment. The MHCAS replicates the ED experience by providing evaluations led by trained psychiatric healthcare professionals and supervised by a full-time consultant psychiatrist. This approach aims to reduce the burden on EDs while ensuring timely and appropriate care for individuals in crisis.
Enhancing Access to Crisis Care and Community-Based Interventions
A central theme in the transformation of mental health services is the emphasis on community-based care, particularly for children and young people (CYP). NHS England’s Five Year Forward View for Mental Health emphasized the importance of improving access to 24/7 crisis resolution and liaison mental health services tailored to CYP. The Transforming Children and Young People’s Mental Health Provision Green Paper further reinforced this goal by recommending that savings from reduced hospital stays be reinvested into community-based crisis response. This includes expanding access to intensive home treatment and ensuring that local community teams provide ongoing support to individuals in crisis.
One of the key strategies for achieving this is the integration of mental health professionals into emergency and community services. For example, the implementation of Mental Health Joint Response Cars has embedded mental health expertise within local authority (LA) services, enabling more effective responses to individuals in urgent need. These initiatives aim to divert demand away from A&E departments by ensuring that the appropriate professionals are deployed to manage mental health crises in the community. Additionally, the “Right Care, Right Person” approach emphasizes collaboration with police and other emergency services to ensure that individuals receive the most suitable care based on their specific needs.
Expanding Liaison Psychiatry Services and Integrated Care Models
Liaison psychiatry services play a critical role in the transformation of crisis care by providing psychiatric assessments and interventions in emergency departments and hospital wards. During the pandemic, the demand for these services was re-evaluated, with a focus on expanding their reach and effectiveness. The North East London NHS Foundation Trust (NELFT) has emphasized the importance of ensuring that all local emergency departments have dedicated liaison mental health teams. This aligns with the broader goal of improving the accessibility and responsiveness of crisis care services across the region.
In addition to ED-based services, liaison psychiatry teams have been integrated into ambulance control rooms and other urgent care settings. This allows mental health professionals to provide on-the-scene assessments and interventions, reducing the need for unnecessary hospital admissions. The implementation of such models has been supported by initiatives such as the “MINT” (Mental Health Integration and Transformation) program, which aims to improve services for individuals with complex mental health needs, including those with personality disorders, eating disorders, and those requiring mental health rehabilitation.
Supporting Individuals with Learning Disabilities and Autism
A significant aspect of the transformation in crisis care and liaison mental health services has been the focus on improving support for individuals with learning disabilities and autism. These populations often face unique challenges in accessing mental health services, including communication barriers and the need for tailored interventions. As part of the transformation plans, there is a commitment to ensuring that crisis services are adapted to meet the specific needs of these individuals. This includes providing reasonable adjustments in crisis care settings and ensuring that individuals are not subjected to inappropriate out-of-area placements.
The Greater Manchester Mental Health NHS Foundation Trust (GMMH) has reported progress in this area, including the opening of a Section 136 suite at North Manchester General Hospital. This dedicated space provides a safe and appropriate environment for individuals detained under the Mental Health Act, ensuring that they receive timely and specialist assessments. The trust has also implemented an Enhanced Community Model to improve the accessibility and navigability of community mental health services. These efforts are part of a broader strategy to ensure that individuals with learning disabilities and autism receive care that is both effective and respectful of their rights and needs.
Measuring the Impact of Service Transformations
The success of crisis care and liaison mental health service transformations is often measured through key performance indicators such as wait times, recovery rates, and the number of individuals receiving timely interventions. For instance, GMMH has reported a 26% increase in the number of people receiving help from its Improving Access to Psychological Therapies (IAPT) service, with waiting times reduced by 13% and recovery rates improved by 24%. These outcomes highlight the potential benefits of expanding access to crisis care and integrating mental health professionals into emergency and community services.
Moreover, the establishment of new off-site mental health crisis assessment units has shown promise in reducing the burden on emergency departments. The MHCAS model, for example, has demonstrated the ability to provide timely and effective assessments without the need for hospital admission. This approach not only improves the efficiency of mental health care but also enhances the overall experience for individuals in crisis by offering a more supportive and less stigmatizing environment.
Conclusion
The transformation of crisis care and liaison mental health services represents a significant shift in the approach to mental health care, emphasizing community-based interventions, emergency department diversion, and integrated crisis response models. These changes have been driven by the challenges posed by the pandemic and the recognition that traditional inpatient models are often insufficient to meet the growing demand for mental health support. By expanding access to 24/7 crisis care, embedding mental health professionals in emergency and community settings, and adapting services to meet the needs of vulnerable populations, mental health systems are better positioned to provide timely, effective, and person-centered care. Continued investment in these initiatives, along with rigorous evaluation of their impact, will be essential to ensuring their long-term success and sustainability.
