The WHO safe community program for injury prevention: evaluation of the impact on injury severity

Despite the fact that injuries consume a considerable amount of health care resources world-wide, 3.5 million people die from unintentional injuries each year. To handle this central public health problem, WHO has introduced the Safe Community accreditation for injury prevention programs. This study was to investigate the impact from a Safe Community program with regard to injury severity. Data were collected in Motala municipality (population = 41 000), Östergötland county, Sweden, during one year before and one year after program intervention, from two sources: registration of trivial (AIS 1) and non-trivial (AIS 2–6) unintentional injuries from all acute care episodes in the area and recollection of hospital bed days from discharge registers. The incidence of non-trivial injuries treated in health care was found to have decreased by 41% (95% confidence interval, 37–45%), while the trivial injuries increased by 16% (9–22%). The larger decrease of non-trivial injuries was observed in all ages and injury event environments. The total number of bed days at emergency hospitals due to injuries decreased by 39% (37–41%) from 1983–84 to 1989, while the hospital bed utilization for other reasons decreased by 9% (8–9%). The study showed that implementation of a WHO Safe Community program led to the harm from unintentional injuries within the community being considerably more reduced than that of the injury incidence. In future assessments of injury prevention programs, classification of injury severity should be included to increase the validity of inter-program comparisons.     

Community-based injury prevention: effects on health care utilization.

BACKGROUND: Worldwide, an estimated 78 million people are disabled each year because of unintentional injuries and about 3 million die. The WHO Safe Community model is a framework for community-based injury prevention programmes. The aim of this study is to evaluate the outcome on health care utilization of a Safe Community programme. METHODS: The incidence of injuries treated at health care facilities in an intervention municipality (pop. 41,000) was compared to the injury incidence in a control municipality (pop. 26,000). The incidence was recorded immediately before and one year after programme implementation from registrations made during all first-contact health care visits and from examination of hospital discharge registers. RESULTS: The incidence of health care treated injuries in the intervention area had decreased by 13% (95% CI: 9-16%) from 119 (95% CI: 115-122) per 1000 population-years to 104 (95% CI: 101-107). In the control area, the corresponding injury incidences were 104 (95% CI: 100-108) and 106 (95% CI: 102-109). The hospital-treated injuries in the intervention area decreased by 15% (95% CI: 7-24%) from 19 (95% CI: 17-20) per 1000 population-years to 16 (95% CI: 15-17), while in the control area, the incidences remained at 13 (95% CI: 11-14) per 1000 population-years. Utilization of acute care in the intervention area for reasons other than injuries increased by 8% (95% CI: 6-10%), while in the control area, the number of visits did not show significant change. CONCLUSION: This first controlled evaluation showed that an injury prevention programme based on local action groups can significantly reduce injuries requiring health care in a community. Local prevention can provide a complement to national level campaigns.     

Obesity, Survival, and Hospital Costs—Findings from a Screening Project in Sweden

OBJECTIVE: Our aims were to estimate 1) the costs of hospital treatment and 2) the value of lost production due to early death associated with overweight and obese patients, and then to extrapolate the findings to national costs. METHODS: We use regression models to analyze survival, expected number of days in hospital treatment for patients with different body mass index (BMI), and costs with data obtained from screening of 33,196 middle-aged subjects living in Malm?, Sweden, and collected during a 15-year follow-up period. We subsequently scale up costs to national aggregate level using the BMI prevalence data from the screening project to the national population. RESULTS: The total excess hospital (somatic, psychiatric) care cost (Swedish krona or SEK) for the national health-care budget, excess as compared to normal weight patients for obese (BMI > 30) and overweight (25 < or = BMI < 30) was estimated to SEK2155 million per annum (269 million dollars, assuming 1 dollar = SEK8), or about 2.3% of total hospital care costs in Sweden. The corresponding indirect costs due to early death were estimated to SEK2935 million (367 million dollars). For males at age 55, the potential hospital costs saving, excluding costs of the intervention that could be gained by an intervention that successfully and safely could alter the weight of an obese individual to become normal weight, was estimated on average to SEK4434 (554 dollars) per annum. CONCLUSION: Hospital treatment costs are found to be higher for obese and overweight patients than for normal weight patients indicating potential cost savings especially on indirect costs by effective, safe and low cost weight-loss intervention.     

The Economic Impact for Farm Injury in Minnesota, 2004–2010

Only 2% of Minnesota’s employed population worked in agriculture between the years 2005 and 2012. However, this small portion of the state’s employed population accounted for 31% of total work-related deaths in the state during that same time period. During a similar time period, 2007–2013, the contribution of agriculture to Minnesota’s gross domestic product increased from approximately 1.5% to about 2.3%. This article describes the economic impact of injuries related to farm work between the years 2004 and 2010. Using hospital discharge data and the Census of Fatal Occupational Injuries (CFOI), estimates of the number of injuries and fatalities related to agricultural work were compiled. A cost of illness model was applied to these injury and fatality estimates to calculate the related indirect and direct costs in 2010 dollars. Estimated total costs, in 2010 dollars, ranged between $21 and $31 million annually over the 7-year study period. The majority of the costs were attributable to indirect costs, such as lost productivity at work and home. Fatal injuries accrued the largest proportion of the estimated costs followed by hospitalized and nonhospitalized injuries. A sensitivity analysis was performed to evaluate the impact each selected data source had upon the cost estimate. The magnitude of the costs associated with these injuries argues for better surveillance of injury related to agriculture to prioritize resources and evaluate intervention and prevention programs.     

Long-term effects of community-based injury prevention on the island of Vaerøy in Norway: a 20-year follow up

AIM: A multifactorial injury prevention programme started in 1981 and ran for about 10 years in an island community in Norway with a population of about 1,000. A study was undertaken to evaluate effects of the programme over a period of 20 years. METHODS: Injuries were recorded by the one medical doctor on the island for several years during the period 1970-2001. The programme was carried out very intensively from 1981 to 1987. The intensity gradually decreased to a medium level that lasted until about 1994, when it was further reduced to a low level. RESULTS: The injury incidence rate was reduced from 17.7% in 1980 (n = 188) to 9.7% in 1987 (n = 97) with relative risk reduced to 0.55 (95% CI 0.44-0.70, p < 0.0001). In 2001, an incidence rate of 9.6% was observed (n = 91). An even higher reduction was observed for serious injuries. The age groups 15-24 and 65+ showed the most distinct reductions from 1980 to 2001 while minor reduction was observed in children (0-14 years). The incidence rate of traffic injuries was reduced by 77% in spite of an increase in the number of motor vehicles. Occupational, home, and other injuries were reduced by 38%, 35%, and 49% respectively. The incidence rates were 2.6-3.0 times higher for men than for women through the 20-year observation period. CONCLUSION: This study indicates that a long-lasting multifactorial community-based intervention in a small community with defined aims may lead to a considerable and long-lasting reduction in injuries.     

Review of Australian health economic evaluation – 245 interventions: what can we say about cost effectiveness?

Background

Elderly injuries are a recognized public health concern and are due to two factors; osteoporosis and accidental falls. Several osteoporosis pharmaceuticals are considered cost-effective, but intervention programs aiming at preventing falls should also be subjected to economic evaluations. This study presents a cost-effectiveness analysis of a community-based elderly safety promotion program.

Methods

A five-year elderly safety promotion program combining environmental structural changes with individually based measures was implemented in a community in the metropolitan area of Stockholm, Sweden. The community had around 5,500 inhabitants aged 65+ years and a first hip fracture incidence of 10.7 per 1,000 in pre-intervention years 1990–1995. The intervention outcome was measured as avoided hip fractures, obtained from a register-based quasi-experimental longitudinal analysis with several control areas. The long-term consequences in societal costs and health effects due to the avoided hip fractures, conservatively assumed to be avoided for one year, were estimated with a Markov model based on Swedish data. The analysis holds the societal perspective and conforms to recommendations for pharmaceutical cost-effectiveness analyses.

Results

Total societal intervention costs amounted to 6.45 million SEK (in Swedish krona 2004; 1 Euro = 9.13 SEK). The number of avoided hip fractures during the six-year post-intervention period was estimated to 14 (0.44 per 1,000 person-years). The Markov model estimated a difference in societal costs between an individual that experiences a first year hip fracture and an individual that avoids a first year hip fracture ranging from 280,000 to 550,000 SEK, and between 1.1 and 3.2 QALYs (quality-adjusted life-years, discounted 3%), for males and females aged 65–79 years and 80+ years. The cost-effectiveness analysis resulted in zero net costs and a gain of 35 QALYs, and the do-nothing alternative was thus dominated.

Conclusion

The community-based elderly safety promotion program aiming at preventing accidental falls seems as cost-effective as osteoporosis pharmaceuticals.     

The role of organizations in community participation--prevention of accidental injuries in a rural Swedish municipality

Accidental injuries are a major public health problem in most of the industrialized world. It is no longer justifiable to accept accidents as unfortunate but unavoidable occurrences. Their prevention is important and appears increasingly possible. The health care sector is uniquely knowledgeable about health hazards and must be more involved in social planning. An intervention programme towards the prevention of accidental injuries based on local epidemiological data has since 1980 been conducted in a geographically defined population in Skaraborg County in western Sweden. This article describes a community intervention approach. The programme has been implemented in a local community with the application of a community oriented and organization oriented perspective. This has above all constituted a starting point for initiating the programme. The programme includes as well active as passive strategies and consists of information, education, supervision and changes in the physical environment. Intersectorial cooperation and community involvement are emphasized.     

Economic evaluation of a community based exercise programme to prevent falls

OBJECTIVE: To assess the incremental costs and cost effectiveness of implementing a home based muscle strengthening and balance retraining programme that reduced falls and injuries in older women. DESIGN: An economic evaluation carried out within a randomised controlled trial with two years of follow up. Participants were individually prescribed an exercise programme (exercise group, n=116) or received usual care and social visits (control group, n=117). SETTING: 17 general practices in Dunedin, New Zealand. PARTICIPANTS: Women aged 80 years and older living in the community and invited by their general practitioner to take part. MAIN OUTCOME MEASURES: Number of falls and injuries related to falls, costs of implementing the intervention, healthcare service costs resulting from falls and total healthcare service costs during the trial. Cost effectiveness was measured as the incremental cost of implementing the exercise programme per fall event prevented. MAIN RESULTS: 27% of total hospital costs during the trial were related to falls. However, there were no significant differences in health service costs between the two groups. Implementing the exercise programme for one and two years respectively cost $314 and $265 (1995 New Zealand dollars) per fall prevented, and $457 and $426 per fall resulting in a moderate or serious injury prevented. CONCLUSIONS: The costs resulting from falls make up a substantial proportion of the hospital costs for older people. Despite a reduction in falls as a result of this home exercise programme there was no significant reduction in healthcare costs. However, the results reported will provide information on the cost effectiveness of the programme for those making decisions on falls prevention strategies.     

Skin diseases caused by ultraviolet radiation: the cost of illness

OBJECTIVES: To assess the annual direct and indirect costs of skin diseases caused by ultraviolet radiation. METHODS: A model for cost-of-illness, including costs for hospital care, primary care, pharmaceuticals, mortality, and morbidity, for approximately 1.8 million inhabitants in Stockholm. RESULTS: The total annual discounted cost-of-illness in Stockholm was approximately 162 million SEK (MSEK; approximate 2002 exchange rate: 1 U.S. dollar = 10 SEK). The indirect costs were predominant and constituted approximately 91 MSEK (56% of total costs), mainly due to an estimated cost of mortality for cutaneous malignant melanoma of 84 MSEK. The direct costs of these diseases, approximately 71 MSEK, were predominated by hospital ambulatory care costs of approximately 33 MSEK. The direct costs constituted approximately 0.4% of the overall health-care costs for hospital care and primary health care in the area. CONCLUSIONS: Skin diseases caused by ultraviolet radiation result in moderate economic losses in the community. Therefore, it may not be easy to make successful prevention of these diseases economically beneficial.     

Injury status and perspectives on developing community safety promotion in China

The objective of this paper is to introduce the epidemiology of injuries in China, and then consider the development of safe communities in regard to injury prevention and safety promotion. The disease spectrum has changed in recent decades in the People's Republic of China. Both in cities and rural areas, injury has become the fifth leading cause of death. At least 800 000 people die from injury each year, and 50 million non-fatal injuries occur, of which 2.3 million lead to disability of varying degrees of severity. The average injury-related death rate in China from 1990 to 1997 was 66 per 100 000, which accounts for 11% of total deaths. The potential years of life lost (PYLL) of injury accounts for 24% of the total, and disability-adjusted life years (DALYs) account for 17%. Main injury causes of death, in descending order, are: suicide, traffic accident, drowning, falling, poisoning, homicide, burn and scald, and iatrogenic injury. Considering China's current injury status and its rapid societal change, injury prevention and safety promotion need to be strengthened further, and there is a special need for the development of Safe Communities programmes. The prevention of injuries through safety promotion has been increasingly focussed on over recent decades. The WHO Safe Community model is recognized as representing an effective and long-term approach to the prevention of injuries at a local level, and has been beneficially applied all over the world. A programme may cover several aspects of injury prevention and safety promotion simultaneously, or only include one or two aspects. In a Safe Community programme in China, children, the elderly, cyclists and their passengers, and farmers should be among the prioritized target populations. However, multi-focussed inter-sectoral programmes have been shown to have additional effects to distinct sectoral programmes.     

Development of a national injury prevention/safe community programme in Vietnam

The aim of this study is to describe the initiation of a national programme on injury prevention/safe community (IP/SC). Market economy, Doi Moi, was introduced in Vietnam in 1986, and since then the injury pattern has been reported to have changed. The number of traffic injury deaths has increased three-fold from 1980 to 1996 and traffic injuries more than four-fold. Injuries are now the leading cause of mortality in hospitals. There are difficulties in obtaining a comprehensive picture of the injury pattern from official statistics and, in conjunction with the work initiated by the Ministry of Health, a number of local reporting systems have already been developed. Remarkable results have been achieved within the IP/SC in a very short time, based on 20 years of experience. An organizational construction system has been built from province to local community areas. Management is based on administrative and legislative documents. IP/SC implementation is considered the duty of the whole community, local authorities and people committees, and should be incorporated into local action plans. The programme is a significant contribution towards creating a safe environment in which everybody may live and work, allowing the stability for society to develop. Implementation of the programme in schools is a special characteristic. The programme will be developed in 800 schools with a large number of pupils (25% of the population). This model for safer schools is considerably concerned and is a good experience to disseminate. The recommendations are that more pilot models of IP/SC should be conducted in other localities and that the programme should be expanded to a national scale. Furthermore, co-operation between sectors and mass organizations should be encouraged and professional skills of key SC members at all levels should be raised.     

Economic evaluation of screening for prostate cancer: a randomized population based programme during a 10-year period in Sweden

Prostate cancer is a growing health problem representing considerable costs. Screening and early curative treatment may reduce morbidity and possibly prevent future escalating costs. However, population screening programmes are generally not well accepted at present due to uncertainty about whether screening for prostate cancer can result in reduced mortality. Evidence from large, randomized, controlled trials is still lacking. The objective of this study was to calculate clinical and economic consequences of general prostate cancer screening based on a limited screening trial in a Swedish community and a decision-tree model. A random selection of 1492 men (50-69 years) were invited to repeated screening in 1987. They have been examined every third year (four rounds). The other 7679 men in the population act as controls. The results show that the total incremental health care costs for prostate cancer will increase by 179 million SEK per year with screening compared to no-screening. The number of detected cases of localized cancer will increase by about 1000, which represents an additional cost of about 158,000 SEK per case. In conclusion, general screening for prostate cancer can be performed with a reasonable cost per detected localized cancer. Information on the long-term effect on life quality and cancer mortality is unknown.     

The burden of fall-related injury among older persons in New South Wales

Objective: To develop a comprehensive estimate of the burden of fall‐related injury among older people in New South Wales. Methods: Fall injuries in 2006/07 were estimated using information from several datasets and the literature. Healthcare costs were calculated using Australia‐Refined – Diagnostic‐Related Group costs for hospital episodes of care and average costs for Emergency Department presentations, ambulance transport and residential aged care (RAC). Ratios of the cost of inpatient care relative to other health services, derived from the literature, were used to estimate the costs associated with these services. Results: In 2006/07, in NSW, there were almost 143,000 falls, among older people, resulting in injuries requiring medical treatment. The total cost of healthcare associated with these falls was estimated at $558.5 million. Although accounting for only 6% of the NSW population aged 65 years and older, persons in RAC accounted for 15% of the total cost of falls injury and 21% of hospital inpatient costs. Conclusion and implications: This study demonstrates the extremely high economic cost of falls in older persons and highlights the disproportionate impact of falls in RAC. The study underscores the urgent need for significant investment in fall‐injury prevention efforts in both the community and RAC settings.     

An Evaluation of an Injury Prevention Campaign in General Practice in Norway

Tellnes G (Department of General Practice, University of Oslo,Frederik Stangs gate 11/13, 0264 Oslo 2, Norway). An evaluationof an injury prevention campaign in general practice in Norway.Family Practice 1985; 2: 91–93. When the community diagnosis was described for two islands,Vaerøy and Røst, in 1970–73 injuries werefound to be the most common single diagnosis. During one year(1979–80) all the injured patients who contacted the districtphysician in the municipality of Vaerøy were recordedin order to study the aetiology of injuries. Based on the experiencefrom this study, art injury prevention programme was designedfor this local community. The campaign started in 1981. A follow-upstudy in 1981–83 evaluated the effect of the preventioncampaign. Two years after the programme started, the occurrenceof injuries had declined by 29 per cent.

Impact of social standing on injury prevention in a World Health Organization Safe Community--intervention outcome by household employment contract

BACKGROUND: Although social inequality in health has been an argument for community-based injury prevention programmes, intervention outcomes with regard to differences in social standing have not been analysed. The objective of this study was to investigate rates of injuries treated in health-care among members of households at different levels of labour market integration before and after the implementation of a WHO Safe Community programme. METHODS: A quasi-experimental design was used with pre- and post-implementation data collection covering the total populations <65 years of age during one year in the programme implementation municipality (population 41 000) and in a control municipality (population 26 000). Changes in injury rates were studied using prospective registration of all acute care episodes with regard to social standing in both areas during the study periods. RESULTS: Male members of households categorized as not vocationally active displayed the highest pre-intervention injury rates. Also after the intervention, males in households classified as not vocationally active displayed notably elevated injury rates in both the control and study areas. Households in the study area in which the significant member was employed showed a post-intervention decrease in injury rate among both men (P < 0.001) and women (P < 0.01). No statistically significant change was observed in households in which the significant member was self-employed or not vocationally active. In the control area, only an aggregate-level decrease (P < 0.05) among members of households in which the significant member was employed was observed. CONCLUSIONS: The study displayed areas for improvement in the civic network-based WHO Safe Community model. Even though members of non-vocationally active households, in particular men, were at higher pre-intervention injury risk, they were not affected by the interventions. This fact has to be addressed when planning future community-based injury prevention programmes.

Cost of work-related injuries in insured workplaces in Lebanon

OBJECTIVE: To estimate the medical and compensation costs of work-related injuries in insured workplaces in Lebanon and to examine cost distributions by worker and injury characteristics. METHODS: A total of 3748 claims for work injuries processed in 1998 by five major insurance companies in Lebanon were reviewed. Medical costs (related to emergency room fees, physician consultations, tests, and medications) and wage and indemnity compensation costs were identified from the claims. FINDINGS: The median cost per injury was US dollars 83 (mean, US dollars 198; range, US dollars 0-16,401). The overall cost for all 3748 injuries was US dollars 742,100 (76% of this was medical costs). Extrapolated to all injuries within insured workplaces, the overall cost was US dollars 4.5 million a year; this increased to US dollars 10 million-13 million when human value cost (pain and suffering) was accounted for. Fatal injuries (three, 0.1%) and those that caused permanent disabilities (nine, 0.2%) accounted for 10.4% of the overall costs and hospitalized injuries (245, 6.5%) for 45%. Cost per injury was highest among older workers and for injuries that involved falls and vehicle incidents. Medical, but not compensation, costs were higher among female workers. CONCLUSION: The computed costs of work injuries--a fraction of the real burden of occupational injuries in Lebanon--represent a considerable economic loss. This calls for a national policy to prevent work injuries, with a focus on preventing the most serious injuries. Options for intervention and research are discussed.     

Health Indicators of a Cohort of Midwest Farmers: Health Outcomes of Participants in the Certified Safe Farm Program

Occupational illness, injury, and fatality rates for those working in production agriculture are higher than in any other industry. A potential risk factor contributing to occupational injuries across all industries is acute or chronic co-morbidity (e.g., obesity, high blood pressure, high cholesterol), and related health issues that increase the risk for an occupational injury or illness. These chronic health conditions have been associated not only with increased risk for injuries, but also higher health-care costs, and greater absenteeism. Certified Safe Farm (CSF) is a comprehensive intervention program aimed to reduce occupational health and safety hazards and to promote general health among farmers. Prior publications have described CSF program efforts to reduce hazardous exposures, disabling injuries, organic dust toxic syndrome, occupational health-care costs, and to increase positive occupational health behaviors. This paper reports on the general health indicators of a cohort of 438 Iowa farm owner/operators enrolled in the CSF program. Overall, this study found that the farming population in Iowa has higher body mass index (BMI), but lower total cholesterol, low-density lipoprotein (LDL), and lower prevalence of hypertension compared to the general population. There was evidence that the combination of high blood pressure, cholesterol, and BMI were related to increased injury rates. Poor self-reported health status was also related to increased injuries but was not related to clinical health indicators. The CSF intervention led to improvements on health outcomes, particularly among those in the 35 to 49 age group. Little research has focused on the individual’s general health status as a predictor of risk of occupational injury. This study suggests the need for additional research and interventions integrating occupational safety and health prevention along with health promotion.
