Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention group will be assessed for risk factors for falls and fractures. This will include medical and medication history, falls and fracture history, cognitive (GPCog) and physical function (IADL) and an objective measure of falls risk – QuickScreen. Physical activity will be measured using the IPAQ and the home environment will be assessed using the Homefast assessment scale. Quality of Life will be measured using the EQ5D and affect using the GDS-15. The anticipated duration of the initial assessment is approximately 60 minutes. At the end of the assessment, the researcher will generate a list of risk factors identified and written suggestions as to how they might be addressed using a template and capacity for free text to individualise some advice.
The intervention group will then receive falls prevention strategies based on risk factors identified. The clinical researcher will pro-actively work with the older person to ensure that risk factors are addressed and interventions carried out.
Exercise in the form of strength and balance training will be recommended and it is anticipated that the majority of the intervention group will be offered this intervention. This will be in the form of the Otago Exercise Program and delivered by the PACS service physiotherapist. Participants will also be referred on to local evidence-based exercise programs (not all delivered through health care) to ensure that they continue exercising on completion of the Otago Exercise Program.
Issues related to safety in the home environment will be referred to the PACS Occupational Therapist.
People with poor vision (and no recent visual assessment) will be referred to their usual eye-care provider or a local optometrist.
Participants taking medications known to increase falls risk will be referred to their GP and encouraged to discuss the ongoing need for these medications. A Home Medication Review will also be encouraged particularly where there is evidence of impaired cognition or any reported difficulties taking medications. A template will be designed to minimise any additional work for GPs. PACS nurses will ensure that appropriate changes are followed through and assist in any issues arising regarding medication
For complex patients with multiple problems, a referral to the POW falls clinic or POW aged care clinics will be organised. Again, a template will be designed to aid with the referral process and minimise additional work for the local GP.
Participants from the intervention group will be asked to fill out an Attitudes to Falls-Related Interventions Scale, to possibly identify and then address the specific concerns raised by particular individuals.
Participants will be reassessed after 6 months using a shorted version of the initial assessment tool. Assessment is estimated to take about 30-45 minutes. Reassessment will be completed by a researcher blinded to group allocation and will be conducted at the participants home. Further, participants will be followed up using monthly calendars and reply paid envelopes for a period of 12 months. Information will be collected with respect to falls, fall related injury, subsequent use of the ambulance service or hospital system and any visits to health care providers in the community. The monthly falls calenders are a single page questionnaire with only 2 questions. Participants are asked to fill it out either after using health care services or after having a fall, or at the end of the month if the participant did not fall. This process is estimated to take no more than 5 minutes.

Comparator / control treatment
The control group will receive standard ambulance care and will additionally be assessed for risk factors for falls and fractures. This will include medical and medication history, falls and fracture history, cognitive (GPCog) and physical function (IADL) and an objective measure of falls risk – QuickScreen. Physical activity will be measured using the IPAQ and the home environment will be assessed using the Homefast assessment scale. Quality of Life will be measured using the EQ5D and affect using the GDS-15. The anticipated duration of the initial assessment is approximately 60 minutes. At the end of the assessment, the researcher will generate a list of risk factors identified and written suggestions as to how they might be addressed using a template and capacity for free text to individualise some advice.
The control group will then receive a written copy of the risk factors identified during the baseline assessment. They will be encouraged to discuss the results with their local GP or other relevant health care provider.
Participants will be reassessed after 6 months using a shorted version of the initial assessment tool. Assessment is estimated to take about 30-45 minutes.

Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation will occur after the baseline assessment has been undertaken but whilst the researcher is with the participant. Group allocation will be concealed from all study investigators and staff using consecutively numbered sealed opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be achieved using computer generated random numbers and randomly permuted block sizes. The single centralised randomisation schedule will be developed by a colleague with no involvement in the study.
