Use of physical restraint in hospital patients: A descriptive study in a tertiary hospital in South Africa.

Background: The use of physical restraint in patient management is a common and emotive issue, and has legal and ethical dimensions.

Objective: To document the prevalence of physical restraint use, patient characteristics associated with physical restraint use, and nurses' and doctors' knowledge and perceptions towards the practice.

Methods: A cross-sectional study of 572 patients, of whom 132 were physically restrained, was conducted in acute wards of a tertiary hospital. Data were collected on the 132 physically restrained patients. Fifty-nine doctors and 159 nurses completed a specially constructed questionnaire. Descriptive statistics were derived and expressed as numbers and percentages.

Results: Prevalence of restraint use was 23% (132/572). The distribution in acute wards was: medical 54.5%; surgical 44.7%; maternity 0.8%; psychiatry none. Mean age (SD) of the restrained patients was 49 years (20.5); 53.8% were male. The commonest types of restraints used were bed rails 93% and wrist belts 12%. Restraints were used largely to protect medical devices and as protection from harm. Less than 15% of the nurses reported having received training and 36% of the doctors reported having received some guidance on the use of restraints. Only a minority of nurses and doctors knew of a hospital policy on restraint use. Documentation on the prescription and indication for the use of restraint was poor.

Conclusion: Prevalence of restraint use is high and poorly coordinated. A policy on the use of restraint and comprehensive guidelines should be developed to guide health care practitioners in the management of patients where restraint cannot be avoided.
