Table 1. Outcome measure collection schedule and approach.

Outcome	Schedule	Data Collection Approach(es)
Proportion of patients with mobilisation alarms	T1, T2, T3	Direct observation of ward beds during 2-week audits; completed by researchers and/or research assistants at each health service. At T2, the audit will be completed before the provision of research evidence.
Health service falls management guidelines	T2, T3	Audit of official health service falls management documents for mobilisation alarm use guidelines; completed by local principal investigator at each health service.
Staff attitudes to mobilisation alarms and relevant research evidence	T1, T2, T3	Individual and/or focus group interviews exploring staff’s attitudes towards alarms and adoption of the evidence. These will last up to 30 minutes with health service staff, including ward staff and falls portfolio managers and will be conducted by researchers who are not directly involved with clinical practice on the ward.
Cost-benefit of a disinvestment intervention to reduce or remove mobilisation alarms, for falls and falls injuries	T1, T2, T3	Costs: index admission, 30-day readmissions, cost of mobilisation alarms and other falls prevention strategies, cost of implementation activities; and (ii) Effect: effect is expressed as a cost (or cost saving) to the health service (falls and fall injuries).

T1 = timepoint one; T2 = timepoint two; T3 = timepoint three
