Paraffin dangers, health and socioeconomic consequences: Urgent need for policy action.

Illuminating paraffin (kerosene) is the primary cooking fuel for approximately two million South Africans. The highly flammable and toxic fuel is burnt in poorly made stoves that are prone to malfunction and are associated with accidental fires, burns and household air pollution. However, the fuel continues to be used as it is easily decanted, widely available in neighbourhood outlets, perceived as affordable, and often the only available option for low-income urban settlements. It is anticipated that increased and enforced home congestion during COVID-19 lockdowns will exacerbate exposure of homebound families to unsafe energy, especially during the cold winter months. Based on an accumulation of evidence on the health and socioeconomic impacts of paraffin, this article advocates for its expedited phase-out and substitution with safer energy.

Preventing Fall Injury.

Falls are the leading cause of injury, premature institutionalization, and long-term disability in elderly adults worldwide, with a fall-related fatality in the United States every 19 minutes.1 According to the Centers for Disease Control and Prevention,2 3 million people over 65 years of age receive emergency room treatment for fall injuries at an average cost of $30 000. The annual cost of fall injuries was more than $50 billion in 2015.1,2 Community-based interventions effective in preventing falls include exercise, medication, and nutritional management as well as improving safety of the local environment.3 Evidence supporting interventions designed to reduce hospital inpatient falls is less clear despite considerable research aimed at reducing this growing problem. Those injured due to falling during a hospital stay incur higher costs, including a 6-day longer hospital stay, than non-fallers.4 Programs have worked to prevent other "never events," such as wound infections or pressure ulcers, but mixed results have been reported for preventing falls or fall-related injuries in hospitals. This month's Evidence Corner reviews a randomized controlled trial (RCT)5 and a prospective observational study6 that offer important clues on how to prevent hospital inpatient falls.

Preventing deaths and injuries from house fires: a cost-benefit analysis of a community-based smoke alarm installation programme.

BACKGROUND: Operation Installation (OI), a community-based smoke alarm installation programme in Dallas, Texas, targets houses in high-risk urban census tracts. Residents of houses that received OI installation (or programme houses) had 68% fewer medically treated house fire injuries (non-fatal and fatal) compared with residents of non-programme houses over an average of 5.2 years of follow-up during an effectiveness evaluation conducted from 2001 to 2011. OBJECTIVE: To estimate the cost-benefit of OI. METHODS: A mathematical model incorporated programme cost and effectiveness data as directly observed in OI. The estimated cost per smoke alarm installed was based on a retrospective analysis of OI expenditures from administrative records, 2006-2011. Injury incidence assumptions for a population that had the OI programme compared with the same population without the OI programme was based on the previous OI effectiveness study, 2001-2011. Unit costs for medical care and lost productivity associated with fire injuries were from a national public database. RESULTS: From a combined payers' perspective limited to direct programme and medical costs, the estimated incremental cost per fire injury averted through the OI installation programme was $128,800 (2013 US$). When a conservative estimate of lost productivity among victims was included, the incremental cost per fire injury averted was negative, suggesting long-term cost savings from the programme. The OI programme from 2001 to 2011 resulted in an estimated net savings of $3.8 million, or a $3.21 return on investment for every dollar spent on the programme using a societal cost perspective. CONCLUSIONS: Community smoke alarm installation programmes could be cost-beneficial in high-fire-risk neighbourhoods.

Risk factors associated with unintentional house fire incidents, injuries and deaths in high-income countries: a systematic review.

OBJECTIVE: To identify the distinguishing risk factors associated with unintentional house fire incidents, injuries and deaths. STUDY DESIGN: Systematic review. METHODS: A range of bibliographical databases and grey literature were searched from their earliest records to January 2016. To ensure the magnitude of risk could be quantified, only those study types which contained a control group, and undertook appropriate statistical analyses were included. A best evidence synthesis was conducted instead of a meta-analysis due to study heterogeneity. RESULTS: Eleven studies investigating a variety of risk factors and outcomes were identified. Studies ranged from medium to low quality with no high quality studies identified. Characteristics commonly associated with increased risk of house fire incidents, injuries and fatalities included: higher numbers of residents, male, children under the age of 5 years, non-working households, smoking, low income, non-privately owned properties, apartments and buildings in poor condition. Several risk factors were only associated with one outcome (eg, living alone was only associated with increased risk of injurious fires), and households with older residents were at increased risk of injurious fires, but significantly less likely to experience a house fire in the first place. CONCLUSIONS: This best evidence synthesis indicates that several resident and property characteristics are associated with risk of experiencing house fire incidents, injuries or death. These findings should be considered by the Fire and Rescue Services and others with a role in fire prevention. Future research should adopt robust, standardised study designs to permit meta-analyses and enable stronger conclusions to be drawn.

Cost-benefit analysis of fall injuries prevented by a programme of home modifications: a cluster randomised controlled trial.

BACKGROUND: Injuries due to falls in the home impose a huge social and economic cost on society. We have previously found important safety benefits of home modifications such as handrails for steps and stairs, grab rails for bathrooms, outside lighting, edging for outside steps and slip-resistant surfacing for outside areas such as decks. Here we assess the economic benefits of these modifications. METHODS: Using a single-blinded cluster randomised controlled trial, we analysed insurance payments for medically treated home fall injuries as recorded by the national injury insurer. The benefits in terms of the value of disability adjusted life years (DALYs) averted and social costs of injuries saved were extrapolated to a national level and compared with the costs of the intervention. RESULTS: An intention-to-treat analysis was carried out. Injury costs per time exposed to the modified homes compared with the unmodified homes showed a reduction in the costs of home fall injuries of 33% (95% CI 5% to 49%). The social benefits of injuries prevented were estimated to be at least six times the costs of the intervention. The benefit-cost ratio can be at least doubled for older people and increased by 60% for those with a prior history of fall injuries. CONCLUSIONS: This is the first randomised controlled trial to examine the benefits of home modification for reducing fall injury costs in the general population. The results show a convincing economic justification for undertaking relatively low-cost home repairs and installing safety features to prevent falls. TRIAL REGISTRATION NUMBER: ACTRN12609000779279.

Home safety assessment and modification to reduce injurious falls in community-dwelling older adults: cost-utility and equity analysis.

BACKGROUND: This study aimed to improve on previous modelling work to determine the health gain, cost-utility and health equity impacts from home safety assessment and modification (HSAM) for reducing injurious falls in older people. METHODS: The model was a Markov macrosimulation one that estimated quality-adjusted life-years (QALYs) gained. The setting was a country with detailed epidemiological and cost data (New Zealand (NZ)) for 2011. A health system perspective was taken and a discount rate of 3% was used (for both health gain and costs). Intervention effectiveness estimates came from a Cochrane systematic review and NZ-specific intervention costs were from a randomised controlled trial. RESULTS: In the 65 years and above age group, the HSAM programme cost a total of US$98 million (95% uncertainty interval (UI) US$65 to US$139 million) to implement nationally and the accrued net health system costs were US$74 million (95% UI: cost saving to US$132 million). Health gains were 34 000 QALYs (95% UI: 5000 to 65 000). The incremental cost-effectiveness ratio (ICER) was US$6000 (95% UI: cost saving to US$13 000), suggesting that HSAM is highly cost-effective. Targeting HSAM only to older people with previous injurious falls and to older people aged 75 years and above were also cost-effective (ICERs=US$1000 and US$11 000, respectively). There was no evidence for differential cost-effectiveness by gender or by ethnicity (Indigenous New Zealanders: Maori vs non-Maori). CONCLUSIONS: As per other studies, this modelling study indicates that the provision of an HSAM intervention produces considerable health gain and is highly cost-effective among older people. Targeting this intervention to older people with previous injurious falls is a promising initial approach before any scale up. TRIAL REGISTRATION NUMBER: ACTRN12609000779279.

The short-term cost of falls, poisonings and scalds occurring at home in children under 5†years old in England: multicentre longitudinal study.

BACKGROUND: Childhood falls, poisonings and scalds, occurring predominantly in the home, are an important public health problem, yet there is limited evidence on the costs of these injuries to individuals and society. OBJECTIVES: To estimate National Health Service (NHS) and child and family costs of falls, poisonings and scalds. METHODS: We undertook a multicentre longitudinal study of falls, poisonings and scalds in children under 5 years old, set in acute NHS Trusts across four UK study centres. Data from parental self-reported questionnaires on health service resource use, family costs and expenditure were combined with unit cost data from published sources to calculate average cost for participants and injury mechanism. RESULTS: 344 parents completed resource use questionnaires until their child recovered from their injury or until 12 months, whichever came soonest. Most injuries were minor, with >95% recovering within 2 weeks, and 99% within 1 month of the injury. 61% emergency department (ED) attendees were not admitted, 35% admitted for ≤1 day and 4% admitted for ≥2 days. The typical healthcare cost of an admission for ≥2 days was estimated at £2000-3000, for an admission for ≤1 day was £700-1000 and for an ED attendance without admission was £100-180. Family costs were considerable and varied across injury mechanisms. Of all injuries, scalds accrued highest healthcare and family costs. CONCLUSIONS: Falls, poisonings and scalds incur considerable short-term healthcare and family costs. These data can inform injury prevention policy and commissioning of preventive services.

Reducing the risk of injury from table saw use: the potential benefits and costs of automatic protection.

The use of table saws in the United States is associated with approximately 28,000 emergency department (ED) visits and 2,000 cases of finger amputation per year. This article provides a quantitative estimate of the economic benefits of automatic protection systems that could be designed into new table saw products. Benefits are defined as reduced health-care costs, enhanced production at work, and diminished pain and suffering. The present value of the benefits of automatic protection over the life of the table saw are interpreted as the switch-point cost value, the maximum investment in automatic protection that can be justified by benefit-cost comparison. Using two alternative methods for monetizing pain and suffering, the study finds switch-point cost values of $753 and $561 per saw. These point estimates are sensitive to the values of inputs, especially the average cost of injury. The various switch-point cost values are substantially higher than rough estimates of the incremental cost of automatic protection systems. Uncertainties and future research needs are discussed.

Burden, distribution and impact of domestic accidents in a semi-urban area of coastal Tamil Nadu, India.

The objectives of this study are to determine the prevalence of domestic accidents, describe the factors associated with domestic accidents and assess the medical and economical consequences of domestic accidents. Community-based cross-sectional study was conducted in a semi-urban area of Tamil Nadu during February 2013. A total of 3947 study participants were interviewed using a structured questionnaire. Study variables included were socio-demography, housing conditions, epidemiological factors, medical and economical consequences of domestic accidents. Means and proportions were calculated. The prevalence of domestic accidents was 12.7%. Out of 500 domestic accidents, falls (54.4%) was the most common type of domestic accident. Females and the respondents in age group of 21-40 years were more commonly affected. About 60% of victims received treatment. Mean duration of hospital stay, mean amount of money spent for treatment and mean number of days away from routine work for falls category were 16 days, US$25 and 8 days, respectively, which are higher than other types of accidents. The burden and impact of domestic accidents was high. Therefore, in order to prevent and control domestic accidents, promotion of house safety measures and creation of awareness among the community using IEC programmes have to be undertaken.

Head injuries following television-related accidents in the pediatric population.

OBJECT: Current data indicate the rate of head injuries in children caused by falling televisions is increasing. The authors describe these injuries and the cost incurred by them. METHODS: In a single-institution retrospective review, all children treated for a television-related injury at LeBonheur Children's Hospital, a Level I pediatric trauma center, between 2009 and 2013 were identified through the institution's trauma registry. The type, mechanism, and severity of cranial injuries, surgical interventions, outcome, and costs were examined. RESULTS: Twenty-six patients were treated for a television-related injury during the study period. Most injuries (22 cases, 85%) occurred in children aged 2-4 years (mean age 3.3 years), and 19 (73%) of the 26 patients were male. Head injuries occurred in 20 patients (77%); these injuries ranged from concussion to skull fractures and subdural, subarachnoid, and intraparenchymal hemorrhages. The average Glasgow Coma Scale score on admission was 12 (range 7-15), and 3 patients (12%) had neurological deficits. Surgical intervention was required in 5 cases (19%). The majority of patients made a full recovery. There were no deaths. The total cost for television-related injuries was $1.4 million, with an average cost of $53,893 per accident. CONCLUSIONS: A high occurrence of head injuries was seen following television-related accidents in young children. This injury is ideal for a public education campaign targeting parents, health care workers, and television manufacturers.

Burden on family carers and care-related financial strain at the end of life: a cross-national population-based study.

BACKGROUND: The rising number of deaths from cancer and other life-limiting illnesses is accompanied by a growing number of family carers who provide long-lasting care, including end-of-life care. This population-based epidemiological study aimed to describe and compare in four European countries the prevalence of and factors associated with physical or emotional overburden and difficulties in covering care-related costs among family carers of people at the end of life. METHODS: A cross-national retrospective study was conducted via nationwide representative sentinel networks of general practitioners (GPs). Using a standardized form, GPs in Belgium, The Netherlands, Italy and Spain recorded information on the last 3 months of life of every deceased adult practice patient (1 January 2009-31 December 2010). Sudden deaths were excluded. RESULTS: We studied 4466 deaths. GPs judged family carers of 28% (Belgium), 30% (The Netherlands), 35% (Spain) and 71% (Italy) of patients as physically/emotionally overburdened (P < 0.001). For 8% (Spain), 14% (Belgium), 36% (The Netherlands) and 43% (Italy) patients, GPs reported difficulties in covering care-related costs (P < 0.001). Patients <85 years of age (Belgium, Italy) had higher odds of having physically/emotionally overburdened family carers and financial burden. Death from non-malignant illness (vs. cancer) (Belgium and Italy) and dying at home compared with other locations (The Netherlands and Italy) were associated with higher odds of difficulties in covering care-related costs. CONCLUSION: In all countries studied, and particularly in Italy, GPs observed a considerable extent of physical/emotional overburden as well as difficulties in covering care-related costs among family carers of people at the end of life. Implications for health- and social care policies are discussed.

How socioeconomic status influences road traffic injuries and home injuries in Rome.

Road traffic injuries (RTI) and home injuries (HI) are a relevant public health problem, especially among people living in deprived areas. The objective of this study was to explore the relationship between morbidity, hospitalisation, mortality from RTI and HI, and socioeconomic status (SES) of the area of residence. RTI and HI surveillance based on the Emergency Information System, the Hospital Information System and the Mortality Registry of Lazio region are the three sources of this study to create a unique surveillance system. For each subject, the SES index (5 levels) of its census tract of residence was obtained. The study population included emergency department admissions (year 2005) of residents in Rome, Italy. Incidence Rate Ratios (IRRs) have been estimated using Poisson Regression. The rates of RTI and HI emergency department visits were higher among the most deprived level of SES (IRR = 1.27, 95% CI: 1.24-1.30; IRR = 1.33, 95% CI: 1.29-1.37, respectively) compared to the most privileged ones; a similar result was found for hospitalisation (IRR = 1.19, 95% CI: 1.08-1.32; IRR = 1.11, 95% CI: 1.01-1.22). A strong relation was found between RTI mortality rates and poor level of SES. The study concluded that RTI and HI incidence were associated to sociodemographic factors.

Home injuries in Italy: patterns of injury and the most exposed people.

Home injuries are a significant public health problem in developed and developing countries. To support future policies for reducing their occurrence and controlling their consequences, this study investigated the home injuries situation in Italy in 1999, using a nation-representative sample. The weighted correspondence analysis showed four different patterns of injury and seven profiles of the people most exposed to them. As results of this study falls were followed by bumps and cuts requiring specialist assistance then burns. Women were the most exposed to burn and fall risks and men to the risk of cuts and bumps. Among the elderly and children, falls and bumps leading to fractures, wounds or other consequences were frequent. The risks were highest for people with a lower level of education. Bumps and cuts were prevalent among unmarried and with the highest education level subjects. These injury risks were higher for young males. Cuts in adults doing do-it-yourself jobs had the worst consequences, while domestic work cuts generally did not need medical treatment. Burns occurred almost exclusively in the kitchen (90%) and did not need specialist assistance. Because home injuries are largely preventable, an efficient public health policy could promote and disseminate home safety culture.

Smoke alarm giveaway and installation programs: an economic evaluation.

BACKGROUND: The burden of residential fire injury and death is substantial. Targeted smoke alarm giveaway and installation programs are popular interventions used to reduce residential fire mortality and morbidity. PURPOSE: To evaluate the cost effectiveness and cost benefit of implementing a giveaway or installation program in a small hypothetic community with a high risk of fire death and injury through a decision-analysis model. METHODS: Model inputs included program costs; program effectiveness (life-years and quality-adjusted life-years saved); and monetized program benefits (medical cost, productivity, property loss and quality-of-life losses averted) and were identified through structured reviews of existing literature (done in 2011) and supplemented by expert opinion. Future costs and effectiveness were discounted at a rate of 3% per year. All costs were expressed in 2011 U.S. dollars. RESULTS: Cost-effectiveness analysis (CEA) resulted in an average cost-effectiveness ratio (ACER) of $51,404 per quality-adjusted life-years (QALYs) saved and $45,630 per QALY for the giveaway and installation programs, respectively. Cost-benefit analysis (CBA) showed that both programs were associated with a positive net benefit with a benefit-cost ratio of 2.1 and 2.3, respectively. Smoke alarm functional rate, baseline prevalence of functional alarms, and baseline home fire death rate were among the most influential factors for the CEA and CBA results. CONCLUSIONS: Both giveaway and installation programs have an average cost-effectiveness ratio similar to or lower than the median cost-effectiveness ratio reported for other interventions to reduce fatal injuries in homes. Although more effort is required, installation programs result in lower cost per outcome achieved compared with giveaways.

The cost-effectiveness of falls prevention interventions for older community-dwelling Australians.

OBJECTIVE: To evaluate the cost-effectiveness of strategies designed to prevent falls among older people. METHODS: A decision analytic Markov model of interventions designed to prevent falls was developed. Incremental cost-effectiveness ratios (ICERs) using quality adjusted life year (QALYs) as the measure, were calculated for those interventions aimed at the general population (home exercise, group exercise, tai chi, multiple and multi-factorial interventions); high-risk populations (group exercise, home hazard assessment/modification and multi-factorial interventions); and specific populations (cardiac pacing, expedited cataract surgery and psychotropic medication withdrawal). Uncertainty was explored using univariate and probabilistic sensitivity analysis. CONCLUSION: In the general population, compared with no intervention the ICERs were tai chi ($44,205), group-based exercise ($70,834), multiple interventions ($72,306), home exercise ($93,432), multifactorial interventions with only referral ($125,868) and multifactorial interventions with an active component ($165,841). The interventions were ranked by cost in order to exclude dominated interventions (more costly, less effective) and extendedly dominated interventions (where an intervention is more costly and less effective than a combination of two other interventions). Tai chi remained the only cost-effective intervention for the general population. IMPLICATIONS: Interventions designed to prevent falls in older adults living in the community can be cost-effective. However, there is uncertainty around some of the model parameters which require further investigation.

Consequences of non-fatal electrical injury: findings of community-based national survey in Bangladesh.

This study was designed to document the consequences of electrical injury in Bangladesh. A community-based cross-sectional survey was conducted from January to December 2003. Nationally representative data were collected from 171,366 rural and urban households, comprising a total of 819,429 population. Face-to-face interview was chosen as a data collection method. The overall rate of electrical injury was 73.7 per 100,000 population-year. The rate of permanent disability due to electrical injury in Bangladesh was 0.366 per 100,000 population-year. Among the total 604 non-fatal electrical injuries in the survey, 282 (46.7%) had suffered from temporary disabilities for different durations. A total of 172 students were injured from electrical injury and among them 139 (80.8%) missed school for different durations due to their illness. Mean duration of absence from school was 9.72 days (SD±10.98), ranging from 1 to 45 days. Among the working people average duration of work loss was 10.56 days (SD±14.98), ranging from 1 to 90 days. About 39% of the total patients with electrical injury were contributors to their family income. For each family the expenditure for each seriously injured patient due to electrical injury was USD 271. Electrical Injury is a major cause of morbidity in Bangladesh. It is responsible for significant loss of school days and work days and creating serious health and economic hardship for the inflicted families. A nationwide prevention program needs to be developed to address this problem.

Epidemiologic trend in elderly domestic injury.

BACKGROUND: The elderly constitute about 12% of the American population, with a projected increase of up to 25% in 2050. Elderly domestic injuries have been recognized as a major cause of morbidity and mortality. The objective of this study is to determine the 4-y national trend in elderly domestic injury, and we hypothesize that the home remains a significant source of injury. METHODS: Data on elderly patients ≥ 65 y was extracted from the National Trauma Data Bank's National Sample Project (NSP). Elderly patients with home injuries were compared with non-home injuries. Subsets of hospitalized patients were analyzed for trends in injury site over a 4 y period. Multivariate analysis was performed to determine the predictors of hospitalization and in-hospital mortality. RESULTS: A total of 98,288 patients, representing a weighed estimate of 472,456 elderly patients were analyzed. Forty-two percent of all injuries in the study population occurred at home, followed by motor vehicle crashes (MVC) at 25%. Home injuries as a proportion of annual injuries increased from 37% in 2003 to 40% in 2006. Majority (57%) were admitted to the floor and 14% to the intensive care unit (ICU). On multivariate analysis, African-Americans and Asians were less likely to be hospitalized (odds ratio (OR) 0.57 and 0.50, respectively, with females 47% less likely than males to die after hospitalization (P < 0.001). CONCLUSIONS: Home injuries remain the most significant source of elderly hospitalizations after trauma. With a rapidly growing elderly population, there is a need to recognize this specific location of injury and create directed preventive measures to avert elderly domestic injuries.

Spring cleaning as a safety risk: results of a population-based study in two consecutive years.

BACKGROUND: Spring cleaning is a popular tradition in Iran as well as in many other countries. The purpose of our study was to determine the pattern and compare the incidence of spring cleaning related injuries in Tehran, in the years 2007 and 2008. METHODS: In the year 2007, a household survey was performed in Tehran by random cluster sampling. The survey was repeated in May 2008 with the same clusters and starting points, but different households. The incidence of spring cleaning related injuries, the age and sex of injured person(s), the mechanism, type and cost of injuries were recorded through semi-structured interviews. The incidence rates of injuries and injuries leading to health visits (severe) according to sex and age groups were calculated. Data were analyzed using SPSS and STATA statistical softwares. RESULTS: The incidence of all and severe spring cleaning related injuries were 3.8 (3.0 - 4.8) and 1.6 (1.1-2.3) per 1000, respectively. The most common mechanisms of injuries were falls, followed by cutting and lifting heavy objects or overexertion. Falls were also the main mechanism of severe injuries. The most common injuries were open wounds, followed by superficial injuries (including contusions) and sprain and strain. Among severe injuries, the most frequent injuries were open wounds and contusions, followed by dislocations. The injuries were most common among women with an incidence of about 8.4 per 1000 in women older than 18 years of age (severe injuries: 3.4 per 1000 (2.2-5.1)). CONCLUSION: The incidence of spring cleaning related injuries is high enough to raise concern in health system authorities. It could be estimated that about 23,927 to 38,283 persons get injured during the spring cleaning in Tehran at the beginning of every Persian new year. In addition, about 8,773-18,344 of these cases are expected to be severe enough to lead to medical attention (considering 7,975,679 as the population of Tehran at the time of study). Improving awareness of families, especially young women, regarding the scope and importance of spring cleaning safety can be suggested as the first population-based strategy to decrease the incidence of these injuries.

Preventing bath water scalds: a cost-effectiveness analysis of introducing bath thermostatic mixer valves in social housing.

AIMS: To assess the cost-effectiveness of installing thermostatic mixer valves (TMVs) in reducing risks of bath water scalds and estimate the costs of avoiding bath water scalds. METHODS: The evaluation was undertaken from the perspective of the UK public sector, and conducted in conjunction with a randomised control trial of TMVs installed in social housing in Glasgow. Installation costs were borne by the social housing organisation, while support materials were provided by the UK NHS. Effectiveness was represented by the number of families with at-risk bath water temperatures pre- and post-installation, and the number of bath scalds avoided as a result of installation. Differences in the number of families with at-risk temperatures between groups were derived from the RCT. Cost-effectiveness was assessed and a series of one-way sensitivity analyses were conducted. RESULTS: Unit costs associated with installation were calculated to be £13.68, while costs associated with treating bath water scalds ranged from £25,226 to £71,902. The cost of an avoided bath water scald ranged from net savings to public purse of £1887 to £75,520 and at baseline produced a net saving of £3,229,008; that is, £1.41 saved for every £1 spent. CONCLUSION: It is very likely that installing TMVs as standard in social housing in new buildings and major refurbishments accompanied by educational information represents value for money.
