Restrictive interventions on a psychiatric admission ward before and after COVID-19

Restrictive interventions (seclusion, restraint and special observations) are used on psychiatric wards when there are no other means available to keep a patient or others safe. These measures can be traumatic, and the Mental Health Commission and the Health Service Executive are focused on minimising their use. We set out to determine whether, following a COVID related reduction in bed numbers on a high dependency psychiatric ward in St John of God Hospital in Dublin, there was a change in their incidence.

Data on restrictive interventions and challenging behaviours were gathered for 9-month periods before and after March 2020 when COVID related ward changes took place. Figures were also collected on seclusion and restraint for the previous 18 months for a longer-term view. Ward and hospital occupancy levels were also recorded.

Between the two time periods, episodes of seclusion fell by 53% and episodes of restraint by 56%. The hours devoted to special observation declined by 30% and incidents of challenging behaviours fell by 26%. Ward occupancy levels fell by only 5%. The longer-term comparison of figures for seclusion and restraint point towards a downward trend from mid-2019 that was accentuated in the post-COVID period.

The changes found may relate to reduced crowding on the ward or other COVID related factors such as the emphasis on social distancing and a shared sense of purpose on the ward. The longer-term trend points towards an emerging cultural shift. The challenge now is to sustain and build upon these changes.
