Description of intervention(s) / exposure
Specialist Falls and Bone service - coordinating targeted multifactorial falls prevention interventions and adequate assessment and treatment of osteoporosis. The falls prevention interventions are not the intervention of interest rather the service model to provide them.
The specialist service consists of a registered nurse who performs the baseline assessments. A geriatrician assesses participants in a hospital based clinic setting or domicilary visit. The first clinic visit lasts 90 minutes and includes a comprehensive geriatric medical assessment with focused clinical examination including gait and balance assessment with Timed Up and Go Test, Sit to Stand Times Five and Static Balance Assessment. Investigations performed at this clinic and ordered by the Geriatrician include blood tests to assess osteoporosis risk, Bone Mineral Denistometry (BMD), Computerised Tomography (CT) of the brain, x-rays of the thoraco-lumbo-sacral spine and 24 hour ambulatory blood pressure monitoring. The participant is seen again at 6 weeks, 4 months and 12 months after the initial assessment and seen initially within 2 weeks of randomization (aiming for 1 week). These subsequent visits will again be with a Geriatrician. At the week 6 visit the participant will have the results of the relevant investigations reviewed and treatment instituted, such as osteoporosis treatment according to national treatment guidelines including Calcium and Vitamin D supplementation. Falls prevention interventions will be coordinated and arranged by the Geriatrician with the assistance of community based physiotherapists, occupational therapists and podiatrists not employed by the research team per se. Telephone and postal communication with participants and their General Practitioner will be used to communicate changes in treatment. At the 4 month and 12 month visits the Geriatrician will review the falls prevention interventions employed and coordinate additional interventions depending on the outcome of these interventions. For example, should a participant wish to continue an exercise programme following the completion of a programme, community based classes will be sourced or the participant will be referred to a more complex class such as Tai Chi, if they were unable to participate in this previously. In addition, compliance with medication changes will be reviewed and additional changes made as necessary.

Comparator / control treatment
General Practice (GP) coordinated use of targeted multifactorial falls prevention interventions. Enhanced GP service model with falls risk assessment and generic advice provided by the research team for coordination by the GP. The GP is the usual practitioner caring for the participant. There will be no specific GP education, but there exists ongoing education sessions given by the Principal Investigator to the local GP network as part of continuing medical education.

Details on the injuries sustained are obtained from follow-up phone calls and data linkage including hospital admissions, Emergency Department attendances and any investigations performed. Injurious falls will be defined as minor or major depending on the injury sustained and the treatment required by the research team in accordance with previously published definitions. For example lacerations or abrasions which do not require sutures or repeated dressings by community nurses would be termed a minor injury.

Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potentially eligible subjects are recruited from Emergency Department and the community through referrals from health care professionals, or self referrals.
Allocation concealment was achieved by contacting the holder of the allocation schedule at central administration.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Stratified permuted block randomisation using a computer program.
The strata used were:
1. age - 65-79 years and 80 years and older.
2. Fall history - one fall in the prior 12 months and 2 or more falls in the prior 12 months.
Masking / blinding

Summary
Brief summary
Falls are a common occurrence in older people and can have adverse affects on health and independence. It is unclear how best to provide interventions to prevent falls.

The primary aim of this study is to evaluate the effectiveness of a hospital based specialist led falls and bone service at reducing the number of falls and number of fallers in a group of community living older people.

Our hypothesis is that a hospital based specialist service is more effective at assessing fall and osteoporosis risk and coordinating interventions to prevent falls and treat osteoporosis than enhanced General Practice care.
