WHAT IT FOUND

Psychiatric hospital stays for people with intellectual disabilities or autism fell slightly, but restraint use rose sharply.

Beds for those staying over two years closed, while admissions for crises and young people increased. This suggests community services are failing to prevent hospitalisation.

Key findings

01The number of inpatients subject to physical or chemical restraints increased by an average of 4.14 patients per month between February 2018 and January 2024.

02The reduction in total hospital spells was driven entirely by a decrease in patients staying longer than two years, while the number of patients staying under two years remained stable.

03Periods with higher hospital admissions were associated with more non-White inpatients, suggesting these groups are more likely to be admitted for shorter crisis periods rather than long-term care.

What it does not show

The study uses aggregated monthly data, so it cannot show individual patient trajectories or outcomes. Associations found do not prove causation; for example, increased restraints may reflect higher patient acuity rather than service changes. The analysis could not separate the experiences of autistic people without intellectual disabilities from those with intellectual disabilities. Data for August 2022 to March 2023 were missing due to a cyber incident, creating a gap in the timeline. The model could not include all potentially relevant factors, such as Care and Treatment Reviews, due to the limited number of monthly observations.

Declared interests

The authors declared no conflicts of interest. The work was funded by the University of Warwick.

The easy way to misread this

Do not interpret the reduction in total hospital beds as a success in community care. The decrease was only in long-stay patients, while crisis admissions and restraint use increased, suggesting more people are reaching a point of severe distress requiring acute hospital intervention.
