Objective To evaluate the effectiveness of multifactorial assessment and intervention programmes to prevent falls and injuries among older adults recruited to trials in primary care, community, or emergency care settings. Design Systematic review of randomised and quasirandomised controlled trials, and meta-analysis. Data sources Six electronic databases (Medline, Embase, CENTRAL, CINAHL, PsycINFO, Social Science Citation Index) to 22 March 2007, reference lists of included studies, and previous reviews. Review methods Eligible studies were randomised or quasi-randomised trials that evaluated interventions to prevent falls that were based in emergency departments, primary care, or the community that assessed multiple risk factors for falling and provided or arranged for treatments to address these risk factors. Data extraction Outcomes were number of fallers, fall related injuries, fall rate, death, admission to hospital, contacts with health services, move to institutional care, physical activity, and quality of life. Methodological quality assessment included allocation concealment, blinding, losses and exclusions, intention to treat analysis, and reliability of outcome measurement. Results 19 studies, of variable methodological quality, were included. The combined risk ratio for the number of fallers during follow-up among 18 trials was 0.91 (95% confidence interval 0.82 to 1.02) and for fall related injuries (eight trials) was 0.90 (0.68 to 1.20). No differences were found in admissions to hospital, emergency department attendance, death, or move to institutional care. Subgroup analyses found no evidence of different effects between interventions in different locations, populations selected for high risk of falls or unselected, and multidisciplinary teams including a doctor, but interventions that actively provide treatments may be more effective than those that provide only knowledge and referral. Conclusions Evidence that multifactorial fall prevention programmes in primary care, community, or emergency care settings are effective in reducing the number of fallers or fall related injuries is limited. Data were insufficient to assess fall and injury rates. INTRODUCTIONFalls are a major health problem for older adults, through both immediate effects such as fractures and head injuries and longer terms problems such as disability, fear of falling, and loss of independence. 1Prevention of falls and injuries has been a major focus of research, stimulated by ageing populations and by growing awareness of the mortality and morbidity resulting from falls. Earlier reviews of randomised controlled trials of fall prevention interventions concluded that several types of intervention are effective, including training in strength and balance, modification of hazards at home, and withdrawal of psychotropic drugs.2 Multifactorial risk assessment of falls followed by targeting of interventions to an individual's risk factors is an attractive strategy as it could reduce several components of fall risk and would be e...

Introduction: This study reports the epidemiology and outcomes from out-of-hospital

Background. Increased ambulance utilisation is closely linked with Emergency Department (ED) attendances. Pressures on hospital systems are widely acknowledged with ED overcrowding reported regularly in the media and peer-reviewed literature. Strains on ambulance services are less well-documented or studied.Aims. To review the literature to determine the trends in utilisation of emergency ambulances throughout the developed world and to discuss the major underlying drivers perceived as contributing to this increase.Method. A search of online databases, search engines, peer-reviewed journals and audit reports was undertaken. Findings. Ambulance utilisation has increased in many developed countries over the past 20 years. Annual growth rates throughout Australia and the United Kingdom are similar. Population ageing, changes in social support, accessibility and pricing, and increasing community health awareness have been proposed as associated factors. As the extent of their contribution has not yet been established these factors were reviewed.Conclusion. The continued rise in utilisation of emergency ambulances is placing increasing demands on ambulance services and the wider health system, potentially compromising access, quality, safety and outcomes. A variety of factors may contribute to this increase and targeted strategies to reduce utilisation will require an accurate identification of the major drivers of demand.What is known about the topic? Ambulance utilisation is increasing annually throughout the developed world, with previous research suggesting numerous underlying factors. What does this paper add? These factors have not been previously synthesised in the international literature. This narrative review clearly articulates the underlying problems. What are the implications for practitioners? This paper outlines the need for further research of the causes of increased emergency ambulance utilisation, to enable the development of appropriate strategies to manage demand in the future.
