Exercise prescription is no mystery Re: Prevention of falls in older people living in the community
This State of the Art Review  is a welcome affirmation of the evidence on effective approaches to preventing falls in community-dwelling older people. Common and repetitive, falls can have major impact on the quality of life and disability experienced by older people. It is clear that tailored exercise integrated within a small basket of key evidence based interventions is the most effective approach to addressing this silent epidemic.
But at a practical level, we take issue with the review’s assertion that “the specific types and amount of exercise are still to be determined”. The specific elements of an effective exercise prescription were reported in 2011 in an in-depth review of the evidence : a dose of at least 50 hours of challenging balance and progressive strength training, delivered by trained professionals. There is no mystery here.
In the UK, two specific programmes mentioned in the CDC Compendium  are commonplace - the Otago Exercise Programme (OEP)  and the FaME programme [5 & 6]. OEP and FaME were first implemented through a service in South West London in 2000, as reported in the BMJ . A recent audit suggested that falls services nationally are employing appropriately trained professionals, but many services are not meeting the 50 hour effective prescription requirement. 
This review identifies key barriers encountered by a population level approach which resonate with the current UK situation: (a) short-term funding; (b) consistency and fidelity of delivery; (c) availability of providers; (d) clear protocols and quality assessments; (e) training and supervision of professionals; and (f) patient education. These can be addressed, but require system wide action.
All Clinical Commissioning Groups will have finalised plans to address local gaps in finance, quality of care, and health outcomes by the end of June. These Sustainability and Transformation Plans provide the opportunity to translate the potent potential of falls prevention research into local programmes that address avoidable disability and costs, at scale.
