Comparison of restraint data from four countries

Previous studies comparing restraint data from different countries had to rely on randomly published data and showed wide variance in the prevalence of restraint between countries.

To systematically compare datasets from four similar European countries with regard to restraint prevalence.

We analysed whole country or area datasets on restraint from Wales, Ireland, Germany and the Netherlands systematically, thus excluding selection, patient and setting bias. Learning disability (LD) and forensic settings were analysed separately. Differences in proportions between countries were tested by means of Chi square, with number of admissions, admission days and catchment area as denominator and counts of restraint as numerators.

Full datasets were obtained allowing calculations of total admissions, total restraint numbers, numbers of patients involved and total occupied bed days. Data for Ireland is from 2012 and from 2013 for the other three countries. The percentage of patients exposed to restraint varies between 4.5 and 9.4 %. The average number of restraints per patient is stable at around 3 in all countries. Patient numbers affected by restraint per 100 occupied bed days per month vary between 0.095 and 0.200. The Netherlands have the highest use of seclusion (79 %), the longest restraint times and low use of enforced medication. Wales the lowest use of seclusion (2 %), followed by Ireland (29 %) and Germany (49 %). Events per 100 admissions per month vary between 17 and 21. Patients affected by restraint per 100 admissions per month vary between 5.4 and 7.5. LD services account for a disproportionately high number of restraint events.

Patient related restraint data are remarkably similar between countries. Type and length of restraint still vary significantly.
