Influencing factors of the implementation of mechanical restraint in open psychiatric ward: a retrospective study (2016–2021)

Among psychiatric inpatients in open wards, those subjected to multiple restraints exhibited earlier occurrence of the first restraint after admission, prolonged hospital stays, and relatively higher serum creatine kinase levels at admission. These findings suggest that in clinical practice, repeated restraint may potentially prolong hospitalization duration. Monitoring serum creatine kinase levels at admission may aid in identifying patients at risk for repeated restraints. Furthermore, early risk identification and the implementation of alternative interventions are critical to reducing the necessity for restraint interventions.
