RESUMO
Background: Serum gamma-glutamyltransferase (γ-GT), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) levels often increase in metabolic diseases. Objective: This study was conducted to determine which liver enzymes are strongly associated with metabolic syndrome (MetS), how they interact to produce different probability estimates, and what cutoff levels should be used to guide clinical decision-making. Methods: The researchers examined the insurance-based medical checkup data of 293,610 employees ≥35 years years of age, who underwent medical checkups between April 1, 2016, and March 31, 2017. Liver enzyme levels were grouped into quartiles. The association and interaction of liver enzymes with MetS were examined using logistic regression, and receiver operating characteristic (ROC) analyses were used to determine the optimal cutoff values for each liver enzyme in detecting the prevalence of MetS. Results: High levels of γ-GT and ALT were more strongly associated with MetS than AST. At various levels, the tested liver enzymes were found interactive, and associated with the likelihood of MetS prevalence. ROC analysis underscored the significance of all liver enzymes in predicting the development of MetS. The cutoff values for each liver enzyme were determined. Conclusion: This findings of this study directly support the identification of MetS risks within the population, prioritize prevention strategies, and potentially inform policy formulation.

Background: Japan has implemented a national lifestyle guidance intervention programme for potential metabolic syndrome among adults aged 40-74 years; however, there is limited evidence regarding the causal impact of this intervention. The study aims to determine the causal effect of this intervention on health outcomes and health care utilisation. Methods: We performed a regression discontinuity design study. A total of 46 975 adults with ≥1 cardiovascular risk factor in 2015 were included in the study. A two-stage evaluation process (stage 1: waist circumference ≥85 cm for men or ≥90 cm for women and ≥1 cardiovascular risk factor; stage 2: body mass index (BMI)≥25 kg/m2 and ≥2 cardiovascular risk factors) was applied. Changes in obesity, cardiovascular outcomes, and health care utilisation were evaluated in a one-year follow-up in the fiscal year 2016. Results: Participants who received lifestyle guidance intervention based on the waist circumference had a statistically significant reduction in obesity outcomes (Δ weight: -0.30 kg, 95% CI = -0.46 to -0.11; Δ waist circumference: -0.26 cm, 95% CI = -0.53 to -0.02; Δ BMI = -0.09 kg/m2, 95% CI = -0.17 to -0.04) but not in other cardiovascular risk factors and health care utilisation. Analyses based on BMI and results according to demographic subgroups did not reveal significant findings. Conclusions: The provision of this intervention had a limited effect on health improvement and a decrease in health care costs, health care visits, and length of stay. A more intensive intervention delivery could potentially improve the efficacy of this intervention programme.

This study aimed at examining the effect of continued use of home health care resources on end-of-life care at home in older patients with cancer. This retrospective cohort study was conducted using medical and long-term care claims data of 6435 older patients with cancer who died between April 2016 and March 2019 in Fukuoka Prefecture. The main explanatory variables were enhanced home care support clinics and hospitals (HCSCs), enhanced HCSCs with beds, conventional HCSCs, other HCSCs, and home visit nursing care. The covariates were sex, age, required level of care, and the Charlson Comorbidity Index. A logistic regression model was used. The results of the multilevel logistic regression analysis showed that the following were significantly associated with end-of-life care at home: use of enhanced HCSCs with beds (odds ratio, OR: 8.66; 95% confidence interval, CI: [4.31-17.40]), conventional HCSCs (OR: 5.78; 95% CI: [1.86-17.94]), enhanced HCSCs (OR: 4.44; 95% CI: [1.47-13.42]), home-visit nursing care (OR: 1.86; 95% CI: [1.42-2.44]), and a severe need for care (OR: 3.89; 95% CI: [2.92-5.18]). The results suggest that the continued use of home health care resources in older patients with cancer who require out-of-hospital care may lead to increased end-of-life care at home. Particularly, use of enhanced HCSCs with beds is most strongly associated with end-of-life care at home.

OBJECTIVES: This study aimed to evaluate the impact of the policy to reduce the reimbursement fee for percutaneous endoscopic gastrostomy (PEG) on the number of PEG procedures performed among older adults with dementia. STUDY DESIGN: Interrupted time series (ITS). METHODS: We used the monthly aggregated data of the number of PEG procedures in older adults with dementia (both broad and narrow definitions), between 2012 and 2018, from the claims data in Fukuoka Prefecture, Japan. A single ITS design was used to estimate changes in the outcome following each intervention (i.e., first, second, and third interventions performed in 2014, 2015, and 2016, respectively). A controlled ITS design was applied to estimate the effects after the sequence of interventions (pre-intervention: 2012-2014; post-intervention: 2016-2018). The control group comprised patients with malignant head and neck tumors who underwent PEG procedures outside the scope of this policy restriction. RESULTS: The number of PEG procedures decreased significantly only in the month wherein the third intervention was introduced (broad definition: IRR = 0.11, CI = 0.03-0.49; narrow definition: IRR = 0.15, CI = 0.03-0.75). No significant difference was observed between the treatment and control groups during the post-intervention phase. CONCLUSIONS: The impact of fee-revision policy for PEG on the decrease in PEG procedures among older adults with dementia is remarkably minimal. It is difficult to reduce unnecessary PEG procedures by relying on this financial incentive alone. Policy decision-makers should consider methods to prevent inappropriate use of artificial nutrition for older adults at their end-of-life stage by reforming the health delivery system.

BACKGROUND: Patients with Parkinson's disease often experience sleep disorders. Hypnotics increase the risk of adverse events, such as injuries due to falls. In this study, we evaluated the association between hypnotics and injuries among older adults with Parkinson's disease. METHODS: The study used a nested case-control design. The participants were 5009 patients with Parkinson's disease aged ≥ 75 years based on claims data between April 2016 and March 2019 without prescription hypnotics 1 year before the study started. Hypnotics prescribed as oral medications included benzodiazepines, non-benzodiazepines, orexin receptor antagonists, and melatonin receptor agonists. The incidences of outcomes, including injuries, fractures, and femoral fractures, were determined. Each case had four matched controls. Conditional logistic regression analyses were performed to calculate the odds ratios and 95% confidence intervals for the number of hypnotics taken per day for each type of hypnotic. RESULTS: The proportion of participants taking at least one type of hypnotic was 18.6%, with benzodiazepines being the most common. The incidence of injuries, fractures, and femoral fractures was 66.7%, 37.8%, and 10.2%, respectively. Benzodiazepines significantly increased the risk of injuries (odds ratio: 1.12; 95% confidence interval: 1.03-1.22), and melatonin receptor agonists significantly increased the risk of femoral fractures (odds ratio: 2.84; 95% confidence interval: 1.19-6.77). CONCLUSIONS: Benzodiazepines and non-benzodiazepines, which are not recommended according to current guidelines, were the most prevalent among older adults with Parkinson's disease. Benzodiazepines significantly increased the risk of injuries, and melatonin receptor agonists significantly increased the risk of femoral fractures.

Metabolic syndrome (MetS) prevalence has increased globally with considerable morbidity and economic burden at both individual and national levels. Japan is the first and only country that has introduced a nationwide lifestyle guidance intervention program to manage and control MetS. We conducted a quasi-experiment approach-regression discontinuity design-to evaluate the impact of this intervention on health outcomes at the population level. We retrospectively collected data of adults aged ≥35 years who participated in health checkups in 2015. Age in 2015 was used as the assignment variable, and an age of 40 years old was the threshold because those with MetS aged ≥40 were required to receive lifestyle guidance intervention. Among 26,772 MetS adults, those who received the intervention had significant reductions in obesity measurements (bodyweight, waist circumference, and body mass index [BMI]) after 1 year of this intervention. Blood pressure was also significantly reduced in men after 1 year of undertaking the intervention. The results were similar when including demographic, socioeconomic, and behavioral covariates and using alternative functional forms to estimate the impact, or when bandwidths around intervention thresholds were changed. Our results showed that lifestyle guidance intervention for MetS has an important impact on weight loss and blood pressure reduction at the population level. This intervention could address the high burden of obesity and cardiovascular diseases in Japan and other countries with an unmet need for MetS prevention and management.

This study aimed to determine whether there are disparities in the utilization of home-based care services according to income level among people aged 75 years or older in Japan. The research team used administrative claims data from April 2014 to March 2018 for people aged 75 years or older in Fukuoka Prefecture. Subjects were categorized according to income level using medical insurance claim data. Associations between income level and usage days of inpatient care, outpatient care, home medical care, and usage number of home-based long-term care (LTC) services were evaluated. Furthermore, medical and LTC costs were evaluated and adjusted for gender, age, and level of LTC needs. The team used generalized linear models (GLMs) to estimate medical and LTC services utilization, as well as the potential influence of gender, age, care needs level, and death as risk factors. The study analyzed 31,322 subjects, among whom 17,288 were in low-, 12,755 were in middle-, and 1399 were in high-income groups. The results of GLMs showed the number of home medical care days was 59.45, 62.24, and 69.66 days for users from low-, middle-, and high-income groups, respectively. Correspondingly, the number of home-based LTC services used was 668.84, 709.59, and 833.14 times. This study suggests that older adults with lower incomes had relatively low utilizations of home-based care services and high utilizations of nonhome-based LTC services. Policymakers should implement policies focused on people who need care to tackle socioeconomic inequalities in home-based care.

AIM: This study examined whether there is an association between continuous care rehabilitation (CR) and the risk of fracture hospitalization among people with Parkinson's disease (PwP) aged >75 years with mild-to-moderate care needs level. METHODS: A retrospective study design based on the merging of medical claims and long-term care insurance claims data was used. Before propensity score matching, of the 2177 participants, 222 received continuous CR, whereas 1955 did not. After matching using a 1:4 ratio, we identified 222 patients in the CR group and 888 patients in the non-CR groups. We carried out a survival analysis to clarify the association between CR and the risk of fracture hospitalization. RESULTS: After matching, there was a significant difference between the CR and non-CR groups in 3 years (stratified log-rank test by age P = 0.036) and in 4 years (stratified log-rank test by age P = 0.011). The CR group was significantly associated with delays of hospital admission due to fracture within 3 years (hazard ratio 0.54; 95% confidence interval 0.29-0.99; P = 0.047) and within 4 years (hazard ratio 0.52; 95% confidence interval 0.30-0.88; P = 0.010). CONCLUSIONS: Our study showed that older people with Parkinson's disease who continuously received CR had a lower risk of fracture hospitalization in 3 and 4 years than those who did not receive CR or received interrupted CR. Considering our participants with a mild-to-moderate care needs level, a sustainable CR service might benefit people with Parkinson's disease from an early time when their activities of daily living are still intact and cognitive function has not deteriorated.

BACKGROUND: The cost-sharing impact on hospital service utilization of different services is a critical issue that has not been well addressed worldwide. This study aimed to investigate the cost-sharing effects based on income status on hospital service utilization of different services among elderly people in Japan and provide a comprehensive examination and discussion for the reasonability of a cost-sharing system. METHODS: The data were extracted from the Latter-Stage Elderly Healthcare Insurance database in the fiscal year 2016. A total of 610 182 insured people aged ≥75 years old, with 155 773 hospitalization patients, were identified. Hospitalization rate, length of stay (LOS), and total hospitalization cost were used to test the statistical significance among patients categorized by income levels. Generalized linear models for total hospitalization cost were constructed based on bed types to further assess different hospital service utilization. RESULTS: For medical chronic care and psychiatric beds, which both required long-term care treatment, much higher hospitalization rates were observed in the patients with low- and middle-income levels than patients with high-income level. The LOS and total hospitalization cost of the patients with low- and middle-income levels were significantly higher than the patients with high-income level treated in medical chronic care and psychiatric beds. For psychiatric beds, the total hospitalization cost for patients with low-income level was significantly higher than that for patients with highincome level. CONCLUSION: The cost-sharing policy in Japan, especially the cap for out-of-pocket needs further determination. The importance of community-based care services needs to be emphasized, and the collaboration between hospitals and community-based care facilities should be enhanced.

This study aimed to comprehensively evaluate whether income affects long-term health outcomes for older patients who underwent percutaneous coronary intervention (PCI) provided by a universal health coverage system. Data were from the Latter Stage Elderly Healthcare Insurance database in Fukuoka Prefecture, Japan. A total of 5625 individuals aged ≥65 years who underwent PCI in 2014-2016 were included. Cox proportional hazards models were used to assess the association between income status and the incidence of health outcomes. With a median follow-up of 1095 days, 554 acute myocardial infarction (AMI) cases, 1075 stroke cases, 1690 repeat revascularization cases, and 1094 deaths were observed. Risk of all-cause mortality decreased significantly with increasing income level in both unadjusted and adjusted Cox regression models. Patients in the low-income level had a significantly higher rate of AMI (log-rank P = 0.003), stroke (log-rank P = 0.039), and all-cause mortality (log-rank P = 0.001) compared with patients in the high-income level. Observed rates for repeat revascularization also were high in the first year after PCI. In the Japanese universal health setting, low-income patients had a comparatively higher mortality risk after PCI. Poor long-term outcomes might be attributed to patients' baseline characteristics rather than treatment processes.

PURPOSE: Smoking is an important public health issue. Although measures to support smoking cessation have been implemented worldwide, smokers often fail to quit smoking after receiving pharmacotherapies for nicotine dependence. The present study evaluated the cost-effectiveness of varenicline for smoking cessation compared with no pharmacotherapy using actual paid medical cost data in Japan. METHODS: This was a retrospective cohort study of 3657 subjects who had quit smoking with varenicline or no pharmacotherapy. We extracted health examination and medical claim data from a health insurer database for the period 2012-2015. We calculated the incremental cost-effective ratio (ICER) of varenicline using actual paid medical costs for nicotine dependence and the number needed to treat to maintain smoking cessation compared with no pharmacotherapy, considering sex, age, income, and occupation. RESULTS: The 1- and 2-year smoking cessation maintenance rates were 69.7% and 62.4%, respectively. We found that 8.8% of subjects who quit smoking used varenicline for nicotine dependence and the cost per person was Japanese Yen (JPY) 52 177 (U.S. dollars [USD] 474; USD 1 = JPY 110). The ICER of varenicline was dominant when comparing 2-year cessation with 1-year cessation. Male, age <40 years, low income, and manufacturing workers were the most cost-effective variables. CONCLUSIONS: The cost-effective variables of varenicline in the real world were investigated. The results of this study strengthen the evidence regarding which type of people should be targeted for measures to support smoking cessation using varenicline.

BACKGROUND: The number of patients with Parkinson's disease among older adults is rapidly increasing. Such patients mostly take medication and require regular physician visits. However, the effect of physician visit frequency for the treatment for Parkinson's disease has not been evaluated. This study aimed to evaluate the impact of physician visit frequency for Parkinson's disease treatment on mortality, healthcare days, and healthcare and long-term care costs among older adults. METHODS: This study employed a retrospective cohort design utilizing claims data from the Fukuoka Prefecture Wide-Area Association of Latter-Stage Elderly Healthcare Insurance and Long-Term Care Insurance. Patients aged ≥75 years who were newly diagnosed with Parkinson's disease in 2014 were included in this study, following the onset of Parkinson's disease to March 31, 2019. We calculated the restricted mean survival time to evaluate mortality, focusing on the frequency of physician visits for Parkinson's disease treatment. Inpatient days, outpatient days, and healthcare and long-term care costs per month were calculated using a generalized linear model. RESULTS: There were 2224 participants, with 46.5% mortality among those with a higher frequency of physician visits and 56.4% among those with a lower frequency of physician visits. A higher frequency of physician visits was associated with a significant increase in survival time (1.57 months at 24 months and 5.00 months at 60 months) after the onset of Parkinson's disease and a decrease in inpatient days and healthcare costs compared to a lower frequency of physician visits. CONCLUSIONS: A higher frequency of physician visits was significantly associated with longer survival time, fewer inpatient days, and lower healthcare costs. Caregivers should support patients with Parkinson's disease to visit physicians regularly for their treatment.

BACKGROUND: Acute myocardial infarction (AMI) management strategies, involving treatment and post-care, are much more difficult for patients with dementia. This study investigated the factors influencing the use of invasive procedures and long-term care in the management strategies for AMI patients with dementia and the factors associated with these patients' survival. METHODS: This multilevel study combined information from two databases, namely later-stage elderly healthcare insurance and long-term care insurance claims, from 2013 to 2019. Of 214,963 individuals with dementia, we identified 13,593 patients with AMI. The primary outcomes were the use of invasive procedures for treatment and long-term care for post-care management. Survival outcomes were also measured over a 6-year period, adjusting for individual- and regional-level characteristics in multilevel models. RESULTS: A total of 1954 (14.38%) individuals received an invasive procedure during treatment, and 7850 (87.18%) used long-term care for post-care management after AMI. After multivariate adjustment, patients aged ≥ 85 years and women were less likely to receive invasive procedures and more likely to use long-term care. Patients undergoing invasive procedures had a lower use of long-term care. Better survival outcome was significantly associated with invasive management and long-term care, regardless of the type of care. CONCLUSION: Age and sex determine the use of invasive procedures and long-term care after AMI among patients with dementia. AMI patients with dementia receiving invasive procedures and long-term care had better survival outcomes.
RESUMO
The authors examined variations in hemodialysis care and quantified the effect of these variations on all-cause mortality. Insurance claims data from April 1, 2017 to March 30, 2018 were reviewed. In total, 2895 hospital patients were identified, among whom 398 died from various causes. Controlling effects of the facility and secondary medical care areas, all-cause mortality was associated with older age, heart failure, malignancy, cerebral stroke, severe comorbidity, and the first and ninth centile of physician density. Multilevel analyses indicated a significant variation at facility level (σ22 0.27, 95% confidence interval: 0.09-0.49). Inclusion of all covariates in the final model significantly reduced facility-level variance. Physician density emerged as an important factor affecting survival outcome; thus, a review of workforce and resource allocation policies is needed. Better clinical management and standardized work processes are necessary to attenuate differences in hospital practice patterns.

Variations in health care outcomes and services potentially indicate resource allocation inefficiency. Therefore, this study was conducted to examine variations in mortality and hospitalization cases among end-stage renal disease (ESRD) patients receiving hemodialysis (HD) care from medical facilities located in 13 secondary medical care areas (SMAs) of Fukuoka prefecture, Japan. The research was designed as a retrospective, cross-sectional study using insurance claims data. The subjects of the study were older patients (over 65 years old) insured by the Fukuoka prefecture's Latter-Stage Elderly Healthcare Insurance. Using an electronic claims database, we identified patients with chronic kidney disease (CKD) who had received HD care from April 1, 2017 to March 31, 2018. The CKD status was identified using International Classification of Disease, 10th revision code, and HD maintenance status was ascertained using specific insurance procedure codes. A total of 5,243 patients met our inclusion criteria and their records were subsequently reviewed. About 73% (n = 3,809) of patients had admission records during the period studied. Thus, the data regarding hospital length of stay (LOS) and admission costs were analyzed separately. Significant differences in terms of increased risks in hospitalization were evident in a number of SMAs. An increase in mortality risk due to heart failure and malignancy was observed in two separate SMAs. Also, analyzed LOS, total hospitalization cost, and cost per day according to SMAs showed statistically significant variations. The findings highlight the magnitude of the burden of CKD and ESRD in the community. The high prevalence of ESRD, associated mortality, and hospitalized HD patients signal the need for clinicians to assume broader roles in measures against chronic kidney disease through involvement in community awareness programs. To improve patient outcomes, improvement of regional health care provision, the level of medical care, and the development of existing human resources are needed.

OBJECTIVES: We compared the care services use and medical institutional deaths among older adults across four home care facility types. DESIGN: This was a retrospective cohort study. SETTING: We used administrative claims data from April 2014 to March 2017. PARTICIPANTS: We included 18 347 residents of Fukuoka Prefecture, Japan, who received home care during the period, and aged ≥75 years with certified care needs of at least level 3. Participants were categorised based on home care facility use (ie, general clinics, Home Care Support Clinics/Hospitals (HCSCs), enhanced HCSCs with beds and enhanced HCSCs without beds). PRIMARY AND SECONDARY OUTCOME MEASURES: We used generalised linear models (GLMs) to estimate care utilisation and the incidence of medical institutional death, as well as the potential influence of sex, age, care needs level and Charlson comorbidity index as risk factors. RESULTS: The results of GLMs showed the inpatient days were 54.3, 69.9, 64.7 and 75.0 for users of enhanced HCSCs with beds, enhanced HCSCs without beds, HCSCs and general clinics, respectively. Correspondingly, the numbers of home care days were 63.8, 51.0, 57.8 and 29.0. Our multivariable logistic regression model estimated medical institutional death rate among participants who died during the study period (n=9919) was 2.32 times higher (p<0.001) for general clinic users than enhanced HCSCs with beds users (relative risks=1.69, p<0.001). CONCLUSIONS: Participants who used enhanced HCSCs with beds had a relatively low inpatient utilisation, medical institutional deaths, and a high utilisation of home care and home-based end-of-life care. Findings suggest enhanced HCSCs with beds could reduce hospitalisation days and medical institutional deaths. Our study warrants further investigations of home care as part of community-based integrated care.

BACKGROUND: Variation in health care delivery among regions and hospitals has been observed worldwide and reported to have resulted in health inequalities. Regional variation of percutaneous coronary intervention (PCI) was previously reported in Japan. This study aimed to assess the small-area and hospital-level variations and to examine the influence of patient and hospital characteristics on the use of PCI. METHODS: Data provided by the Fukuoka Prefecture Latter-stage Elderly Insurance Association was used. There were 11,821 patients aged ≥65 years with acute coronary syndromes who were identified from 2015 to 2017. Three-level multilevel logistic regression analyses were performed to quantify the small-area and hospital variations, as well as, to identify the determinants of PCI use. RESULTS: The results showed significant variation (δ2 = 0.744) and increased PCI use (MOR = 2.425) at the hospital level. After controlling patient- and hospital-level characteristics, a large proportional change in cluster variance was found at the hospital level (PCV 14.7%). Fixed-effect estimation results showed that females, patients aged ≥80 years old, hypertension and dyslipidemia had significant association with the use of PCI. Hospitals with high physician density had a significantly positive relationship with PCI use. CONCLUSIONS: Patients receiving care in hospitals located in small areas have equitable access to PCI. Hospital-level variation might be originated from the oversupply of physicians. A balanced number of physicians and beds should be taken into consideration during healthcare allocation. A treatment process guideline on PCI targeting older patients is also needed to ensure a more equitable access for healthcare resources.

The presence of comorbid conditions along with heterogeneity in terms of healthcare practices and service delivery could have a significant impact on the patient's outcomes. With a strong interest in social epidemiology to examine the impact of health services and variations on health outcomes, the current study was conducted to analyse the incidence of hemodialysis-associated infection (HAI) as well as its associated factors, and to quantify the extent to which the contextual effects of the care facility and regional variations influence the risk of HAI.A total of 6111 patients with end-stage renal disease who received hemodialysis treatment between 1 October 2015 and 31 March 2016 were identified from the insurance claim database as a population-based, close-cohort retrospective study. Patients were followed for one year from April 1, 2016 to March 31, 2017. A total of 200 HAI cases were observed during the follow-up and 12 patients died within 90 days of the onset of HAI. Increased risks for HAI were associated with moderate (HR 1.73, 95% confidence interval [CI] 1.00-2.98) and severe (HR 1.87, 95% CI 1.11-3.14) comorbid conditions as well as malignancy (HR 1.36, 95% CI 1.00-1.85). Increased risk was also seen among patients who received hemodialysis treatment from clinics (HR 2.49, 95% CI 1.1-5.33). However, these statistics were no longer significant when variations at the level of care facilities were statistically controlled. In univariate analyses, no statistically significant association was observed between 90-day mortality and baseline patients, and the characteristics of the care facility.The results of the multivariate, multilevel analyses indicated that HAI variations were only significant at the care facility level (σ 2.07, 95% CI 1.3-3.2) and were largely explained by the heterogeneity between care facilities. The results of this study highlight the need to look beyond the influence of patient-level characteristics when developing policies that aim at improving the quality of hemodialysis healthcare and service delivery in Japan.

OBJECTIVE: Flood is the most common natural disaster in Australia and causes more loss of life than any other disaster. This article describes the incidence and causes of deaths directly associated with floods in contemporary Australia. METHODS: The present study compiled a database of flood fatalities in Australia in the period of 1997-2008 inclusive. The data were derived from newspapers and historic accounts, as well as government and scientific reports. Assembled data include the date and location of fatalities, age and gender of victims and the circumstances of the death. RESULTS: At least 73 persons died as a direct result of floods in Australia in the period of 1997-2008. The largest number of fatalities occurred in New South Wales and Queensland. Most fatalities occurred during February, and among men (71.2%). People between the ages of 10 and 29 and those over 70 years are overrepresented among those drowned. There is no evident decline in the number of deaths over time. 48.5% fatalities related to motor vehicle use. 26.5% fatalities occurred as a result of inappropriate or high-risk behaviour during floods. CONCLUSION: In modern developed countries with adequate emergency response systems and extensive resources, deaths that occur in floods are almost all eminently preventable. Over 90% of the deaths are caused by attempts to ford flooded waterways or inappropriate situational conduct. Knowledge of the leading causes of flood fatalities should inform public awareness programmes and public safety police enforcement activities.

The aim of this study was to systematically review the published evidence of the impact of health information technology (HIT) or health information systems (HIS) on the quality of healthcare, focusing on clinicians's; adherence to evidence-based guidelines and the corresponding impact this had on patient clinical outcomes. The review covered the use of health information technologies and systems in both medical care (i.e. clinical and surgical) and other areas such as allied health and preventive services. Studies were included in the review if they examined the impact of Electronic Health Record (EHR), Computerised Provider Order-Entry (CPOE), or Decision Support System (DS); and if the primary outcomes of the studies were focused on the level of compliance with evidence-based guidelines among clinicians. Measurements considered relevant to the review were either of changes in clinical processes resulting from a change of the providers' behaviour, or of specific patient outcomes that demonstrated the effectiveness of a particular treatment given by providers. Of 23 studies included in the current review, 17 assessed the impact of HIT/HIS on health care practitioners' performance. A positive improvement, in relation to their compliance with evidence-based guidelines, was seen in 14 studies. Studies that included an assessment of patient outcomes, however, showed insufficient evidence of either clinically or statistically important improvements. Although the number of studies reviewed was relatively small, the findings demonstrated consistency with similar previous reviews of this nature in that wide scale use of HIT has been shown to increase clinician's adherence to guidelines.
