Age-related variation in primary care-type presentations to emergency departments.

BACKGROUND: A significant amount of attention has been paid to the increase in emergency department (ED) presentations in Australia. Questions have arisen regarding whether all of those presenting to the ED are actually in need of true emergency services. Under-standing the characteristics of those patients who may be cared for in non-emergency settings is important for future health system strategies. The aim of this study was to identify age-related variation in primary care type emergency department (ED) presentations over time. METHODS: A secondary analysis of data from the Victorian emergency minimum dataset (VEMD) between 2002-13 was conducted. The main outcomes were patterns of primary care type ED presentations for different ages groups over time, age-specific patterns of specific primary care type exclusion criteria and primary care type ED presentations by residents from aged care facilities. RESULTS: The proportion of triage category 4 or 5 ED presentations that met the criteria for a primary care type visit was greatest in the 0-4-year age group and tended to decrease as the age of the patient increased. Triage category 4 or 5 presentation by ambulance was uncommon in the younger age groups, surpassed 10% in the 50-54-year age group, and was >70% for those aged >90 years. The greater proportion of residential aged care facility patients who arrived by ambulance resulted in a much smaller proportion of primary care type visits. DISCUSSION: There are marked differences by age in the proportion of triage category 4 or 5 ED presentations that met the criteria for primary care type visits. These results indicate it was primarily younger patients who presented to the ED with non-urgent conditions. Most might be able to safely receive care in a primary care setting.

Association of epilepsy and burns - a case control study.

BACKGROUND: General practitioners play a vital role in reducing risk for people with epilepsy through pharmacological prevention of seizures. Burns are the most common injury sustained during epileptic seizure. This article examines the risk of burns among patients with epilepsy in Victoria. METHODS: A case control study was conducted using the Victorian Admitted Episodes Dataset (VAED) from 2000-2005. Odds ratios were adjusted for potential confounders and 95% confidence intervals were calculated comparing burns among epilepsy versus nonepilepsy patients using multivariate logistic regression. RESULTS: Epilepsy was three times more likely to be associated with burns, with women being five times more likely to be burned. Hot drinks, food, fats, cooking oils, steam and household appliances, hot tap water, hot fluids other than water, and hot heating appliances were all significant causes. The strength of association between epilepsy and burns for these types of causes was consistently higher for women compared with men. DISCUSSION: This study has shown a strong association between epilepsy and burns in hospital admissions, and identifies the importance of using routine databases for contributing to the limited knowledge about seizure related burns in epileptic patients.

Avoidable mortality in Victoria between 1979 and 2001.

OBJECTIVE: To describe trends in avoidable mortality (AM) in Victoria by sex, degree of socio-economic disadvantage and remoteness. METHODS: The analysis is based on mortality and population data for 1979-2001 supplied by the Australian Bureau of Statistics (ABS) for Victoria. Total and disease-specific AM rates were age standardised using the direct method. For the period between 1997 and 2001, comparisons of total AM rates by sex were made between metropolitan and rural local government areas (LGAs), and between LGAs grouped into quintiles based on socio-economic disadvantage and categories of remoteness. RESULTS: Total AM rates declined significantly (p < 0.05) in both males and females between 1979 and 2001, but were significantly higher in males compared with females. Total AM rates were significantly higher in rural compared with metropolitan LGAs, from 1997 to 2001 in males and in 1998 in females. Total AM rates in the least disadvantaged quintile were significantly lower than those in the most disadvantaged quintile over the entire five-year period in males and in three years in females. Total AM rates were highest in remote LGAs and lowest in highly accessible LGAs. There were significant declines in ischaemic heart disease, stroke and road traffic accident AM rates among males. In females, IHD, stroke, breast and colon cancer AM rates declined significantly. CONCLUSIONS AND IMPLICATIONS: Despite large declines in AM in Victoria, there are significant differences in rates between the sexes and in the population based on socio-economic status or remoteness. These results provide opportunities for policy makers to prioritise public health and health services interventions, targeting population groups and specific disease conditions to reduce health inequalities.

Age distribution of emergency department presentations in Victoria.

OBJECTIVES: To describe patterns of ED utilisation over time, by patient age group and triage classification. METHODS: Secondary analysis of data from all patients presenting to EDs in Victoria utilising the Victorian Emergency Minimum Dataset (VEMD) for the years 2002-2013. The VEMD includes all hospitals in Victoria with 24 h EDs. RESULTS: The absolute number of presentations to EDs in Victoria has grown by over 52% in the last 11 years. The triage categories of highest urgency (1-3) grew by 89% whereas the categories of lowest urgency (4-5) grew by 33%. Over this period, the 5 year age band with the greatest number of ED presentations has consistently been, by far, children 0-4 years of age. This age group has seen an increase of 29% in ED presentations overall with a >55% increase in Triage 1-3, and an increase of 16% in triage 4-5. For all age groups, there has been little change in the number of triage category 4-5 presentations since 2007/2008. However, for triage categories 1-3, there have been consistent increases in presentations across all age groups. CONCLUSION: The age range with the greatest absolute number of ED presentations in Victoria is children 0-4 years of age. This finding is consistent over time and across all triage classifications. The age range with the second highest absolute number of ED presentations is comprised of those 20-24 years of age. This is in contrast to the frequent public attention placed on the volume of ED presentations by the elderly.

Comparison of health estimates between Victorian Population Health Surveys and National Health Surveys.

OBJECTIVE: The computer-assisted telephone interviewing (CATI) method has grown rapidly in recent years as an epidemiological tool for obtaining data on health issues. However, it is still argued that coverage, methods and lower response rates from CATI surveys compared with face-to-face interviewing may have an impact on the validity of the health estimates obtained. This paper compares demographic and health estimates from the Victorian Population Health Survey (VPHS) 2001, using CATI, with the National Health Survey (NHS) 2001 that is based on face-to-face interviews. METHODS: The profiles of the VPHS (2001) and NHS (2001) respondents were compared, specifically demographic characteristics (age, gender, marital status, country of birth, and employment status) and health-related estimates such as self-reported health status, prevalence of diabetes and asthma, smoking status, daily intake of fruit, categories of psychological distress and private health insurance status. RESULTS: In both surveys, the demographic characteristics and health-related estimates of the adult population were remarkably similar as shown by the similarity of weighted estimates and overlapping confidence intervals. CONCLUSIONS: The degree to which derived estimates correspond in the two independent surveys lends support to the reliability of the CATI method used for collection of routine population health related data.

A public health model of the social determinants of health.

As we move forward in the new century, epidemiologists and public health practitioners are faced with the challenge of reviewing the current direction of epidemiology and its links with public health. While the history of epidemiology has been a successful and productive one, there is a danger that modern epidemiology is becoming too narrow in its scope, concerned primarily with the analysis of risk factors in individuals, while ignoring sociological and ecological perspectives of health. We argue that a theoretical framework to guide the practice of epidemiology is needed which encompasses a role for social determinants of health while simultaneously also acknowledging the importance of behaviour and biology, and the inter-connectedness of all these factors. This paper presents a public health model of social determinants of health, which provides a framework for testing the causal pathways linking social determinant variables with health care system attributes, disease inducing behaviours and health outcomes. This approach provides an improved opportunity to identify and evaluate evidence-based public health interventions, and facilitates stronger links between modern epidemiology and public health practice.

The Victorian ambulatory care sensitive conditions study: rural and urban perspectives.

OBJECTIVES: Ambulatory Care Sensitive Conditions (ACSCs) are those for which hospitalisation is thought to be avoidable with the application of preventive care and early disease management, usually delivered in the ambulatory setting. This study presents detailed analyses of ACSCs as a measure of health outcome that might vary with access to primary health care in rural and urban regions of Victoria. METHOD: The Victorian Admitted Episodes Dataset (VAED), and data from the Health Insurance Commission, Medical Labour Force Annual Survey, socio-economic indexes for areas, and accessibility/remoteness index of Australia were merged to identify individual and aggregate level predictors of urban/rural differentials of ACSCs. Estimates of odds ratios and 95% confidence intervals were based on random effect multi-level generalised linear models. RESULTS: After adjustment for age, sex, and severity of illness, significant predictors of higher admission rates of ACSCs within rural areas include lack of insurance, emergency admissions, higher degree of remoteness, lower population density, lower number of general practitioners/10,000 population by local government area (LGA), lower number of general practitioner visits per person by LGA, and areas with lower socio-economic status, education and occupation, and economic resources. CONCLUSIONS: This study suggests that lack of timely and effective care may have a significant impact on rates of admissions for ACSCs in rural areas of Victoria especially in lower socio-economic groups.

The Victorian Ambulatory Care Sensitive Conditions study: reducing demand on hospital services in Victoria.

Ambulatory Care Sensitive Conditions (ACSCs) are those for which hospitalisation is thought to be avoidable if preventive care and early disease management are applied, usually in the ambulatory setting. The Victorian ACSCs study offers a new set of indicators describing differentials and inequalities in access to the primary healthcare system in Victoria. The study used the Victorian Admitted Episodes Dataset (1999-2000) for analysing hospital admissions for diabetes complications, asthma, vaccine preventable influenza and pneumococcal pneumonia. The analyses were performed at the level of Primary Care Partnerships (PCPs). There were 12,100 admissions for diabetes complications in Victoria. There was a 12-fold variation in admission rates for diabetes complications across PCPs, with 13 PCPs having significantly higher rates than the Victorian average, accounting for just over half of all admissions (6114) and 39 per cent total bed days. Similar variations in admission rates across PCPs were observed for asthma, influenza and pneumococcal pneumonia. This analysis, with its acknowledged limitations, has shown the potential for using these indicators as a planning tool for identifying opportunities for targeted public health and health services interventions in reducing demand on hospital services in Victoria.
