Methods	RCT (individually randomised)
Participants	Setting: Subacute hospital setting, single geriatric ward, Germany N = 98 Sample: 65% women Age (years): 76.1 Baseline Characteristics Bed‐exit alarm N: 48 Age ‐ mean (SD) : NR Female ‐ N (%): NR Medical status defined? ‐ Y/N: N Falls risk defined (with valid tool at baseline)? ‐Y/N: Y Dependency defined? Y/N: Y Cognitive status defined? Y/N: N Usual care N: 50 Age ‐ mean (SD) : NR Female ‐ N (%): NR Medical status defined? ‐ Y/N: N Falls risk defined (with valid tool at baseline)? ‐Y/N: Y Dependency defined? Y/N: Y Cognitive status defined? Y/N: N Inclusion criteria: patients at high risk of falls defined by a score of 3 or more in STRATIFY; requirement for assistance with mobilization during resting time Exclusion criteria: immobility; participation in another trial Pretreatment differences: NR
Interventions	Intervention Characteristics Bed‐exit alarm. Patients fitted with sensors to upper leg at rest time. Based on Wireless Sensing Triple Axis Reference Design. Sensors worn during rest periods 1 to 3 pm and 8 pm to 6 am. Usual care
Outcomes	Number of falls Number of fallers
Duration of the study	During admission period, total trial period 13 months
Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Judgement comment: method of sequence generation not described in adequate detail
Allocation concealment (selection bias)	Unclear risk	Judgement comment: no information provided about allocation methods
Blinding of participants and personnel (performance bias) All outcomes	High risk	Judgement comment: not blinded
Blinding of outcome assessment (detection bias) All outcomes	High risk	Judgement comment: falls recorded by nurses who were not blinded
Incomplete outcome data (attrition bias) All outcomes	Low risk	Judgement comment: author correspondence indicated no loss to follow‐up
Selective reporting (reporting bias)	Unclear risk	Judgement comment: no protocol identified
Method of ascertaining falls	Unclear risk	Judgement comment: no falls definition provided, standard reporting mechanisms used
Baseline imbalance	Unclear risk	Judgement comment: inadequate details on baseline characteristics of patients to make a judgement
Other bias	Low risk	Judgement comment: none detected
