Study objective: To estimate the number of accident and emergency (A&E) attendances, admissions to hospital, and the associated costs as a result of unintentional falls in older people. Design: Analysis of national databases for cost of illness. Setting: United Kingdom, 1999, cost to the National Health Service (NHS) and Personal Social Services (PSS). Participants: Four age groups of people 60 years and over (60-64, 65-69, 70-74, and >75) attending an A&E department or admitted to hospital after an unintentional fall. Databases analysed were the Home Accident Surveillance System (HASS) and Leisure Accident Surveillance System (LASS), and Hospital Episode Statistics (HES). Main results: There were 647 721 A&E attendances and 204 424 admissions to hospital for fall related injuries in people aged 60 years and over. For the four age groups A&E attendance rates per 10 000 population were 273.5, 287.3, 367.9, and 945.3, and hospital admission rates per 10 000 population were 34.5, 52.0, 91.9, and 368.6. The cost per 10 000 population was £300 000 in the 60-64 age group, increasing to £1 500 000 in the >75 age group. These falls cost the UK government £981 million, of which the NHS incurred 59.2%. Most of the costs (66%) were attributable to falls in those aged >75 years. The major cost driver was inpatient admissions, accounting for 49.4% of total cost of falls. Long term care costs were the second highest, accounting for 41%, primarily in those aged >75 years. Conclusions: Unintentional falls impose a substantial burden on health and social services.

Issue addressed This project explored the literature in which key concepts in primary health care and health promotion are overtly applied to the problem of climate change. This paper contains a discussion of the literature relevant to health promotion principles and intervention strategies for addressing climate change mitigation and adaptation in the primary health care sector. The concept of primary health care is that used by the World Health Organization, based on the Declaration of Alma Ata and often referred to as comprehensive primary health care to differentiate it from primary medical care. Methods This was a review of literature identified in electronic databases using two sets of search terms. Set A consisted of ‘climate change or global warming or greenhouse effect’ and set B consisted of 11 key concepts in primary health care and health promotion, for example community resilience, health promotion, social change, food security and economic development. Relevant literature was identified at the intersection of search term A with a term from set B. A search was completed for each set B term. Results This paper reports a discussion of major categories of health promotion interventions, namely health communication, community building and settings approaches and uses examples drawn from literature on community resilience and summer heat. These interventions are all applicable to the primary health care sector. Conclusion There is a small literature on health promotion interventions for climate change mitigation and adaptation but it is incomplete and scattered across many sources. An important area for further research is to link the logic of service provision in primary health care to the logic of mitigation and adaptation in a changing environment. Interventions that link the logic must also link diverse services to provide coherent action on local and domestic scales, the scales at which primary health care acts. Another research gap is in regard to institutional change in the primary health care sector. How do the patterns of knowledge, practice and values need to change in the array of organisations that make up comprehensive primary health care? So what? This literature review can support primary health care agencies to design interventions to address climate change using health communication, community building and settings approaches in the knowledge that there is peer‐reviewed literature to support such initiatives. It also identifies two areas of research that would support institutional adaptation within comprehensive primary health care to enable it to fulfil its role in the societal response to climate change.
