Patient detained in solitary room over four days following psychiatric crisis, probe reveals
Emergency department staff have no clear legal authority to prevent mentally unwell patients from walking out of hospitals while awaiting assessment, a national safety investigation has concluded, forcing clinicians into an impossible ethical and legal bind.
The Health Services Safety Investigations Body (HSSIB) found that the absence of definitive powers places staff in a “legal grey area”, where they must often choose what one senior investigator described as the “least harmful way to break the law”. This can mean either unlawfully detaining someone – a breach of their human rights – or allowing them to leave when they are at grave risk of harm.
The Human Cost of Legal Uncertainty
This ambiguity has devastating human consequences. HSSIB inspectors documented the case of one patient in crisis who was locked in a single room containing only a toilet for more than four days. Staff told investigators it was unsafe to enter the room or leave the door unlocked because the patient was desperate to end their life and repeatedly tried to leave.
“Staff described that the patient was not receiving any therapeutic intervention and it felt ‘cruel’ and ‘inhumane’ for them to be waiting so long for a bed when they were so mentally unwell,” the interim HSSIB report stated. Nichola Crust, a senior safety investigator at the body, said such unclear powers expose patients to “uncertainty, emotional distress and an increased risk of harm at a time when being as safe as possible is paramount”.
A System Under Immense Pressure
The crisis in A&E unfolds against a backdrop of severe systemic pressures on mental health services. A critical shortage of psychiatric beds has led to a 25% annual increase in inappropriate out-of-area placements, with 5,500 such cases recorded in 2023/24 alone. This logjam leaves patients stranded in emergency departments for extended periods.
Compounding this are significant workforce challenges, including staffing shortages and reliance on agency staff, which can disrupt the continuity of therapeutic relationships and care. Furthermore, the HSSIB has identified systemic failures in learning from inpatient deaths and near misses, with disjointed care between NHS trusts, social care, and local authorities.
Deep-seated inequalities persist within the system. Black people are over four times more likely to be detained under the Mental Health Act than white people, and are more likely to experience restraint or forced medication while being less likely to receive therapy. NHS England has introduced frameworks like the Patient and Carer Race Equality Framework (PCREF) to address this, but disparities remain pronounced.
Reform, Rights, and Remaining Gaps
Legislative reform is underway, with a new Mental Health Act receiving Royal Assent in December 2025. The act aims to modernise the 1983 legislation, empower patients, and address racial disparities. However, its practical implementation and the resources required are a concern.
All practice operates within the context of the Human Rights Act 1998. While current clinical practice is largely deemed compatible, the lack of clear legal frameworks for A&E staff creates situations where human rights, such as the right to liberty, can be compromised. Separately, the Royal College of Psychiatrists has raised alarms about the detention of people with mental disorders in immigration removal centres, warning it significantly deteriorates health and increases suicide risk.
The HSSIB, an independent body focused on systemic patient safety issues, has issued a direct call to the government to act. It urges ministers to provide clear legal frameworks to prevent staff from operating in a grey zone and to address the wider systemic failures its investigation has uncovered. The Department of Health and Social Care has been approached for comment.
