Over the course of
a year, 13 wards of a secured national psychiatric hospital in Finland received
information about seclusion and restraint prevention. Four highsecurity
wards (N=88 beds) for men with psychotic illness were then
stratified by coercion rates and randomly assigned to two equal groups. In
the intervention wards, staff, patients, and doctors were trained for six
months in applying six core strategies to prevent seclusion-restraint; six
months of supervised intervention followed. Poisson’s regression analyses
compared monthly incidence rate ratios (IRRs) of coercion and violence
(per 100 patient-days)
