The research, led by Sarah Parry of Pennine Care NHS Foundation Trust and the University of Manchester, together with colleagues at Manchester Metropolitan University, the University of Oxford, and Lancaster University, took the form of a realist review. Unlike a conventional systematic review, which asks whether an intervention works on average, a realist synthesis asks a more granular question: what mechanisms fire in what contexts to produce which outcomes? The team followed the RAMESES reporting standards, searching six academic databases alongside grey literature, and screened 6,174 records down to 45 articles that met their inclusion criteria. Crucially, the evidence base was not left to speak for itself. The researchers refined their initial findings through 32 semi-structured interviews with professionals and people with lived experience of youth mental health crises, testing whether the theoretical account matched reality on the ground.

The scope of the review was deliberately broad. It covered emergency responses for individuals aged 0 to 25, drawing on diverse study designs and stakeholder perspectives, and encompassed the bewildering alphabet soup of models that have emerged internationally: mobile crisis teams, crisis intervention teams, police and clinical early response schemes such as PACER and its multi-agency variant A-PACER, psychiatric emergency response teams, co-response teams, and juvenile mobile crisis programmes. What unites these models is a shared premise: mental health crises are complex, multifaceted events that demand fast responses and multidisciplinary expertise, and no single service, however well intentioned, can meet that demand alone.

The analytical engine of the study was the context–mechanism–outcome configuration, or CMOC. This realist technique breaks down an intervention into the situational contexts that trigger particular reasoning in participants, which in turn produces observable outcomes. Fourteen such configurations were developed and grouped into three thematic domains: the experiences and outcomes of young people and their caregivers, the experiences of the workforce and the quality of cross-agency collaboration, and the organisational impacts and implementation factors that determine whether a model survives beyond its pilot phase. This structure allows the review to move beyond blunt verdicts and explain the causal texture of crisis response.

The findings on what works are strikingly consistent. Effective co-response models were characterised by calm, participatory communication, in which young people were engaged as partners in decisions about their care rather than treated as problems to be managed. Cross-agency collaboration was the second pillar: when police officers and clinicians genuinely worked together, drawing on each other’s expertise in real time, the response was better calibrated to the developmental and clinical needs of the child. The third pillar sat at the system level, in the form of stable funding and interoperable information systems that allowed different agencies to share the information needed for safe, informed decisions. Where these enablers were present, the synthesis found reduced trauma, fewer emergency department presentations, and improved decision-making for patient care.

The contrast with police-only responses was stark. Without clinical support, the review found, police-led interventions heightened distress among young people and increased the use of restrictive practices, including physical restraint and detention. For a child in crisis, the arrival of uniformed officers can itself be traumatising, particularly for young people from communities with strained relationships with law enforcement. The presence of a clinician changes the calculus: it signals that the crisis is being treated as a health event rather than a public order problem, and it brings de-escalation skills and clinical judgement into the moment when they matter most.

Yet the review is candid about the fragility of these gains. Effectiveness varied across contexts, and persistent concerns surround equity, sustainability, and the quality of the underlying research. Overarching factors, including stigma around mental illness, ethical concerns about coercion and consent, and the legal frameworks governing police powers, shaped both implementation and outcomes. In England, for example, Section 136 of the Mental Health Act 1983 gives police the power to remove a person from a public place to a place of safety for assessment, and recent policy shifts such as the Right Care Right Person approach have sought to redefine the boundary between policing and health care. The review suggests that such boundary-drawing succeeds or fails depending on whether health services have the capacity to absorb the demand that shifts their way.

The workforce domain of the synthesis carries important lessons for service designers. Co-response models ask police officers and clinicians to work across professional cultures with different training, different legal powers, and often different instincts about risk. The review indicates that collaboration is not achieved simply by placing two professionals in the same vehicle; it depends on shared understanding, mutual respect, and organisational structures that support joint decision-making. Where those conditions are absent, joint response can degenerate into parallel response, with each professional defaulting to their own playbook and the young person receiving the worst of both worlds.

The organisational findings are equally sobering for policymakers tempted to launch a co-response scheme as a quick fix. The synthesis found that these models can offer safer, trauma-responsive and equitable crisis care for young people only when embedded within well-resourced, clearly governed systems. Stable funding emerged as a make-or-break enabler, reflecting a familiar pattern in which pilot projects demonstrate promise and then collapse when short-term grants expire. Interoperable data systems were similarly essential, allowing clinicians to arrive informed rather than dependent on fragmentary accounts relayed over the radio. Without robust governance and data infrastructure, the review warns, even well-designed models struggle to sustain long-term impact.

The authors conclude with a clear set of priorities: sustained investment and coordinated strategies to strengthen co- and joint-response crisis systems for young people, integrating mental health expertise at every level, fostering genuine police–clinician collaboration, adopting trauma-responsive and culturally responsive practices, and ensuring the governance and data systems that allow services to learn and improve. Funded by the National Institute for Health and Social Care Research under the Care Responders Study, and approved by the Greater Manchester Research Ethics Committee, the review arrives at a moment when health systems internationally are rethinking who should answer a mental health crisis call. Its central message is both hopeful and demanding: the alternative to police-led crisis response exists, it works, and it is neither cheap nor simple, but for young people in their worst moments, the evidence suggests it is worth every pound and every hour of cross-agency negotiation it requires.

The clinical stakes are considerable. Rates of trauma exposure among people with eating disorders are high, and trauma is known to influence both the severity of the illness and how well treatment works. Inpatient care itself carries a paradoxical risk. The very environment designed to restore physical health can become a source of what researchers call treatment-related trauma, or it can re-traumatise patients who arrive with pre-existing histories of abuse, neglect or other adverse experiences. The risk of traumatisation or re-traumatisation rises sharply when treatment is coercive or restrictive, which in eating disorder units is often unavoidable: enforced bed rest, supervised meals, restriction of physical activity and, in severe cases, feeding under duress are all standard tools for managing medically unstable patients.

Trauma-informed care emerged as a response to precisely this tension. At its core, the framework asks services to recognise the prevalence of trauma among the people they treat and to organise care around principles of safety, trustworthiness, choice, collaboration and empowerment. In Australian mental health policy, these ideas have been prioritised for roughly the past ten years, appearing in state and national strategies as a marker of humane, modern practice. Yet policy endorsement does not automatically translate into clinical guidance, and it was this gap between aspiration and operational detail that the review set out to measure systematically.

Methodologically, the team conducted a systematic review following established reporting standards, searching PubMed, PsycINFO and Embase for published guidelines, supplementing these with grey literature searches and direct correspondence with health services across Australia. Eligible documents covered adult inpatient eating disorder treatment in public hospitals. Rather than simply counting mentions of trauma, the researchers applied qualitative thematic analysis, using both deductive coding, in which the five established trauma-informed care principles served as predetermined categories, and inductive coding, in which new themes were allowed to emerge from the material itself. This dual approach allowed them to capture not only whether guidelines addressed trauma but how the concept was being framed when it appeared.

The deductive analysis revealed a striking imbalance. Physical safety dominated the guidelines, and the prevailing logic was that protecting a patient’s medical stability justified restricting their freedom. Choice, collaboration and empowerment, the principles that give trauma-informed care its transformative potential, appeared far less often and were rarely connected to concrete clinical decisions. Some guidelines mentioned trauma or trauma-informed care by name, but most did not consider an individual patient’s trauma history or personal preferences when describing how treatment should be planned and delivered. In effect, the framework’s vocabulary had entered the guidelines without its substance.

The inductive analysis added three themes that sharpen the picture. The first, recognising trauma and trauma-informed care, reflected the simple fact that many documents failed to acknowledge high rates of trauma among eating disorder populations at all. The second, respect for inclusion and diversity, pointed to concerns about invalidating, judgemental or culturally unsafe treatment, which the authors note can itself contribute to treatment-related trauma. The third and perhaps most consequential theme was the balancing of coercive care with trauma-informed care, exposing an unresolved tension at the heart of inpatient eating disorder treatment: how to deliver genuinely necessary restrictive interventions without inflicting psychological harm.

Here the review uncovered its most important finding. When trauma-informed care did appear in the guidelines, it was commonly conceptualised as a style of delivering restrictive interventions more sensitively and supportively, rather than as a framework for minimising or critically examining coercive practices themselves. In other words, the guidelines tended to treat trauma-informed care as a communication technique layered on top of unchanged treatment, softening the tone of enforced feeding or supervised rest without asking whether the restriction was proportionate, whether less coercive alternatives existed, or how the patient’s own perspective might reshape the plan. The researchers warn that without clearer guidance on proportionality and the inclusion of patient perspectives, trauma-informed care risks remaining primarily a style of delivering coercive interventions rather than a framework that genuinely shapes clinical decision-making in inpatient settings.

This distinction matters because the two interpretations lead to very different clinical realities. A service that treats trauma-informed care as a delivery style might train nurses to explain procedures calmly and offer small choices within a rigid regime, changes that are worthwhile but leave the underlying power structure intact. A service that treats it as a decision-making framework would instead interrogate each restrictive practice at the level of the multidisciplinary team, weighing the therapeutic necessity of coercion against its psychological cost, documenting the reasoning, and involving the patient wherever medically feasible. The review suggests that Australian guidelines, taken as a whole, have not yet made this second, harder shift, and that clinicians are therefore left to navigate the tension between safety and autonomy largely on their own.

The findings arrive at a moment of growing international scrutiny of iatrogenic harm in psychiatry, and they carry implications well beyond Australia. Eating disorder inpatient units worldwide rely on restrictive practices that would be unthinkable in most other medical settings, justified by the life-threatening nature of illnesses such as anorexia nervosa. The Australian review does not argue that these practices should be abandoned; the authors acknowledge that prioritising physical safety is legitimate and often necessary. What the analysis exposes is the absence of guidance on where the balance should lie, how it should be struck, and whose voice should be heard in striking it. Guidelines that mandate restriction without addressing its traumatic potential, the study implies, are only telling half of the clinical story.

For the field, the path forward suggested by the review is one of clearer, more explicit operational guidance: guidelines that name trauma prevalence, define proportionality in coercive care, incorporate patient perspectives into treatment planning, and treat safety, trustworthiness, choice, collaboration and empowerment as inputs to clinical decisions rather than as decorative language. Until that happens, the authors conclude, a decade of Australian policy commitment to trauma-informed care has not fully reached the hospital wards where eating disorders are treated, and patients with trauma histories continue to enter units whose own rulebooks are largely silent on the harm those units can cause. The full open-access analysis is available in the Journal of Eating Disorders.
