During an assessment of Child and adolescent mental health wards
Sussex Partnership NHS Foundation Trust provides a Tier 4 inpatient Child and Adolescent Mental Health Service (CAMHS) at Chalkhill. It has one ward, which is 12-bedded mixed gender ward where young people are admitted if they require assessment and treatment for acute mental health needs. The service is registered to provide the following regulated activities: Diagnostic and screening procedures; Assessment or medical treatment for persons detained under the Mental Health Act 1983; Treatment of disease, disorder or injury.
We carried out this assessment to review progress against the warning notice that was issued to the trust following our inspection in June 2023. We also received information of concern from whistleblowers, relatives, stakeholders and staff which raised serious concerns about the safety and quality of care provided to young people on the ward. The concerns included the safety and wellbeing of young people, incidents leading to harm, not enough skilled and competent staff, concerns observations of young people were not completed correctly and poor leadership oversight.
During this inspection we assessed if the service was safe, effective, caring, responsive and well led. We found the service had not made sufficient improvements. The trust had not met the required actions set out in the previous warning notice or the breaches of regulation. Because of this, we issued further warning notices due to significant and ongoing concerns in relation to Regulation 12 Safe care and treatment and Regulation 17: Good Governance.
Before the inspection, the trust already had an improvement plan in place to address concerns raised by NHS England, who commission the service. However, during this inspection, some of these concerns remained, and previous actions taken by the trust had not sufficiently reduced the risks to young people on the ward.
We identified significant concerns about the safety and wellbeing of young people on the ward. We shared this feedback directly with senior leaders at the trust. The trust responded to this feedback and took immediate action to review and address these risks.
The trust agreed to suspend new admissions to the ward and identified alternative placements for young people whose needs could be better met elsewhere. The trust provided us with updates which enabled us to closely monitor the service and engaged with us regularly as part of this monitoring process. On the 05 December 2025, the trust confirmed that all young people had been safely transferred or discharged from Chalkhill. The trust temporarily closed the service so they could focus on making the required improvements. The trust plans to reopen the service in Autumn 2026 once the necessary improvements have been completed.
The Trust has provided us with an Action Plan in response to the concerns found at this assessment.
Mental Health Act and Mental Capacity Act Compliance
Mental Health Act
Staff understood and carried out their roles and responsibilities under the Mental Health Act 1983 and the Code of Practice. They received regular training and demonstrated a good understanding of the Act, Code of Practice, Gillick competence and guiding principles.
Staff ensured they explained young peoples’ rights in a way they could understand. Staff repeated this as needed and clearly recorded it in the young peoples’ care records. Information about rights was displayed in communal areas, including information for informal young people about their right to leave the ward.
Staff knew how to access support from the trust’s Mental Health Act administrators and spoke positively about the guidance provided. The trust completed regular audits to monitor the correct application of the Mental Health Act and used learning from these to improve practice. Staff requested second opinions from a Second Opinion Appointed Doctor when required and stored detention paperwork securely and accessibly.
Young people had access to independent mental health advocacy, and advocates visited the ward regularly. Young people said the advocate was nice and tried to help them.
Staff supported young people to take Section 17 leave. This leave allows young people who are detained under the Mental Health Act to leave the hospital for agreed periods, with permission from their responsible clinician. However, young people reported delays to their leave due to staffing shortages and pressures on the ward.
Mental Capacity Act
Staff supported young people to make decisions on their care for themselves. They understood the service policy on the Mental Capacity Act 2005 and assessed and recorded capacity clearly for young people who might have impaired mental capacity. Staff received and kept up to date with training in the Mental Capacity Act. Staff told us they regularly discussed capacity and consent during meetings about the young peoples’ care and treatment. They also said they would speak to the ward manager or another clinician if they had concerns around capacity.
We saw evidence of capacity and consent recorded in care plans, with capacity to consent to treatment obtained at admission and evidence of this being regularly reviewed. We also saw evidence in care plans of staff attempting to support and engage young people in decision processes before deciding that a patient did not have the capacity to do so. When staff assessed young people as not having capacity, they made decisions in the best interest of young people and considered the young person’s wishes, feelings, culture and history. Staff told us that they held a best interest meeting which would involve the young person, the nursing team, the consultant(s) and the young person’s next of kin, where appropriate.
Staff also demonstrated a good understanding of Gillick competencies, which means they knew how to assess whether a young person (under 16 years of age) had the maturity and understanding to make their own decisions about their care and treatment.
