Physical Restraint Use in Acute Care Hospitals: A Diagnostic Study on Knowledge, Documentation, and Patient Safety...

Background: The use of physical restraints in hospital settings remains a controversial practice due to its ethical, legal, and safety implications. Although restraints are intended to prevent falls or manage agitation, their inappropriate use may compromise patient dignity, autonomy, and quality of care. Current healthcare policies emphasize restraint reduction, appropriate documentation, and professional training as key elements of humanized and safe care. Methods: A descriptive cross-sectional study based on an anonymous self-administered survey was conducted in a tertiary university hospital as the diagnostic phase of a quality improvement project aimed at evaluating healthcare professionals' knowledge, perceptions, and documentation practices related to physical restraint use. A structured ad hoc questionnaire was distributed to registered nurses and nursing assistants working in adult inpatient units using a non-probabilistic convenience sampling strategy. The survey explored training, clinical decision-making, communication with patients and families, awareness of institutional protocols, and use of the electronic health record (EHR). Descriptive analyses and Pearson's chi-square tests were performed using IBM SPSS Statistics. Results: A total of 241 professionals participated. More than half of respondents (54.8%) reported no formal training in physical restraint use, and only 27.4% considered their training sufficient. Although 86.3% stated they were familiar with restraint indications, only 53.5% were aware of the existence of a structured EHR restraint registry, and just 31.0% consistently completed it. Documentation of restraint removal was particularly low (32.9%). Furthermore, significant discrepancies were observed between regulatory definitions of restraints and professionals' perceptions regarding practices requiring formal documentation. Statistically significant associations were identified between professional category, perceived training adequacy, and knowledge of physical restraint indications. Conclusions: This diagnostic phase identified substantial gaps between regulatory requirements, professional knowledge, and real-world documentation practices related to physical restraint use. The findings highlight the need for competency-based training strategies, standardized documentation processes, and strengthened institutional leadership to promote patient safety, regulatory compliance, and the humanization of hospital care.
