Alcohol and burden of disease in Australia: the challenge in assessing consumption.

OBJECTIVE: Alcohol consumption is one of the major avoidable risk factors for disease, illness and injury in the Australian community. Population health scientists and economists use estimates of alcohol consumption in burden of disease frameworks to estimate the impact of alcohol on disease, illness and injury. This article highlights challenges associated with estimating alcohol consumption in these models and provides a series of recommendations to improve estimates. METHODS: Key challenges in measuring alcohol consumption at the population level are identified and discussed with respect to how they apply to burden of disease frameworks. RESULTS: Methodological advances and limitations in the estimation of alcohol consumption are presented with respect to use of survey data, population distributions of alcohol consumption, consideration of 'patterns' of alcohol use including 'bingeing', and capping exposure. Key recommendations for overcoming these limitations are provided. Implications and conclusion: Alcohol-related burden has a significant impact on the health of the Australian population. Improving estimates of alcohol related consumption will enable more accurate estimates of this burden to be determined to inform future alcohol policy by legislators.

Evidence-based care for alcohol use disorders is affordable.

OBJECTIVE: Despite efficacious treatment, alcohol use disorders contribute significantly to the disability burden. Although wider dissemination of evidence-based health care may impact on the population burden, the affordability of this strategy is unknown. This article compares the cost-effectiveness of current treatment for alcohol use disorders with the cost-effectiveness of optimal treatment, a hypothetical treatment scenario that has been informed by evidence-based practice to determine the affordability of such an approach. METHOD: This study calculated the cost-effectiveness in the Australian population of evidence-based health care for alcohol harmful use and alcohol dependence, as defined by the International Classification of Diseases, Injuries, and Causes of Death, 10th Revision. Outcome was calculated as years lived with disability (YLD) averted. Data from the Australian National Survey of Mental Health and Wellbeing, in conjunction with published meta-analyses and expert reviews, were used to estimate 1-year costs (1997-98 Australian dollars) and YLD averted by current health care services as well as costs and outcomes for an optimal strategy of evidence-based health care. RESULTS: Of those currently seeking treatment, approximately 45% of those with alcohol harmful use and 58% of those with alcohol dependence receive an evidence-based intervention. The cost of this care was estimated at 73 million dollars, resulting in a cost per YLD averted of 96,813 dollars for harmful use of alcohol and 98,095 dollars for alcohol dependence. Under optimal care for harmful use, costs declined and health gains doubled, substantially reducing the cost per YLD averted to 8861 dollars. For dependence, costs doubled, but optimal treatment resulted in increased health gains, reducing the cost per YLD to 57,542 dollars. CONCLUSIONS: Evidence-based care for alcohol use disorders would produce greater population health gain at an increased cost for alcohol dependence but at a reduced cost for harmful use of alcohol. For both disorders, there are substantial increases in cost-effectiveness.

The alcohol hangover.

PURPOSE: To review the cause, pathophysiologic characteristics, cost, and treatment of alcohol-induced hangover. DATA SOURCES: A MEDLINE search of English-language reports (1966 to 1999) and a manual search of bibliographies of relevant papers. STUDY SELECTION: Related experimental, clinical, and basic research studies. DATA EXTRACTION: Data in relevant articles were reviewed, and relevant clinical information was extracted. DATA SYNTHESIS: The alcohol hangover is characterized by headache, tremulousness, nausea, diarrhea, and fatigue combined with decreased occupational, cognitive, or visual-spatial skill performance. In the United States, related absenteeism and poor job performance cost $148 billion annually (average annual cost per working adult, $2000). Although hangover is associated with alcoholism, most of its cost is incurred by the light-to-moderate drinker. Patients with hangover may pose substantial risk to themselves and others despite having a normal blood alcohol level. Hangover may also be an independent risk factor for cardiac death. Symptoms of hangover seem to be caused by dehydration, hormonal alterations, dysregulated cytokine pathways, and toxic effects of alcohol. Physiologic characteristics include increased cardiac work with normal peripheral resistance, diffuse slowing on electroencephalography, and increased levels of antidiuretic hormone. Effective interventions include rehydration, prostaglandin inhibitors, and vitamin B6. Screening for hangover severity and frequency may help early detection of alcohol dependency and substantially improve quality of life. Recommended interventions include discussion of potential therapies and reminders of the possibility for cognitive and visual-spatial impairment. No evidence suggests that alleviation of hangover symptoms leads to further alcohol consumption, and the discomfort caused by such symptoms may do so. Therefore, treatment seems warranted. CONCLUSIONS: Hangover, a common disorder, has substantial morbidity and societal cost. Appropriate management may relieve symptoms in many patients.
