Use of the least intrusive coercion at Danish psychiatric wards: A register-based cohort study of 131,632 first and subsequent coercive episodes within 35,812 admissions.

Objective: Psychiatric legislation in Denmark implies a principle of using the least intrusive types of coercion first. The intrusiveness is not universally agreed upon. We examined the order in which coercive measures during admission were used, implying that the first used should be less intrusive than the following types.
Methods: For coercive episodes reported to the national administrative register for the period 2011-16, the order of 12 legal coercive interventions during each admission was examined. Comparing with mechanical restraint, the odds ratio (OR) and confidence interval (95%CI) of being first or subsequent used types were estimated using conditioned (96,611 episodes) and unconditioned (131,632 episodes) logistic regression models, stratified on sex.
Results: Totally 17,796 patients aged 18+ were subjected to at least one coercive episode. The median time between admission and the first episode was 4 days in men and 6 for women. For females, involuntary detention, forced feeding, coercive treatment of somatic disorder, locking of doors and close observations in females were used before mechanical restraint, and forced follow-up, involuntary electro convulsive therapy (ECT), forced treatment, use of gloves and straps, physical restraint and forced intramuscular medication was used later. In men, only involuntary detention was used before mechanical restraint, while involuntary ECT, close observations, administration of drugs, use of gloves and straps, physical restraint and forced intramuscular medication was used after mechanical restraint.
Conclusion: The order of used coercive measures is not consistent with the international ranking of the least intrusive types, especially in men and in younger adults.
