ABSTRACT Data from the 2009 and 2010 Medical Expenditure Panel Survey (MEPS) were used to estimate the annual incremental healthcare expenditures associated with anxiety disorders, for the ambulatory adult population of the U.S. Individuals 18 years and older, who reported a diagnosis of, or had a medical event associated with anxiety disorder(s), were classified as anxiety population. Multivariate regression analyses, using generalized linear models, were conducted to calculate incremental costs associated with anxiety disorders. 8.74% of adult respondents reported being diagnosed with anxiety disorder(s). The annual overall healthcare expenditure associated with anxiety disorders was estimated at $1657.52 per person (SE: $238.83; p < 0.001). Inpatient visits, prescription medications, and office-based visits together accounted for almost 93% of the overall cost. Given the prevalence of self-reported anxiety disorders in MEPS, their total direct medical expenditure is estimated at approximately $33.71 billion in 2013 US dollars, meaning this category of mental illnesses absorbs a significant portion of the U.S. healthcare resources.

    ABSTRACT: To develop a measure of the burden of comorbid disease from the MED-ECHO data base (Québec), the so-called Charlson index was adapted to International Classification of Disease (ICD-9) codes. The resulting comorbidity index was applied to the study of inpatient death in 33,940 patients with ischemic heart disease. Multiple logistic regression was used to relate inpatient death to its predictors, including gender, principal diagnosis, age, and the comorbidity index. Various transformations of the comorbidity score were performed, and their effect on the predictive accuracy was assessed. The comorbidity index was constantly and strongly associated with death. From a statistical viewpoint, the best results were obtained when the index was transformed into four dummy independent variables (the area under the receiver-operating curve is then 0.87). In a validation analysis performed on 1990-1991 MED-ECHO data (36,012 admissions with ischemic heart disease), the comorbidity index has the same statistical properties. We conclude that the Charlson index may be an efficient approach to risk adjustment from administrative data bases, although it should be tested on other conditions.

    ABSTRACT: This study was undertaken to estimate the magnitude of medical care expenditures among persons with respiratory conditions in the USA in 1996, and the increment in expenditures attributable to these conditions. The study data were derived from the 1996 Medical Expenditure Panel Survey, a national sample of 21,571 persons. Of the 21,571, 1,027 reported one or more respiratory condition. After weighting, the individuals may represent about 12.1 million persons in the USA. All medical care expenditures of these individuals were tabulated, stratified by comorbidity status, and then compared to those among persons with nonrespiratory conditions or with no conditions. Regression techniques were then used to estimate the increment of healthcare expenditures attributable to the respiratory conditions. From a national total of $45.3 billion, medical care expenditures averaged $3,753 among persons with respiratory conditions. Hospital stays comprised the largest component (45%). The per capita increment in total expenditures attributable to respiratory conditions ranged from $1,003-2,588, from a national total ranging from $12.1-31.3 billion. The total medical care expenditure of persons with respiratory conditions was estimated to be $45.3 billion, of which $12.1-31.3 billion represents an increment in expenditures associated with the conditions themselves.

    ABSTRACT: Anxiety disorders are a group of common mental disorders that impose a significant economic burden on the healthcare system and society. For this review of published literature on the pharmacoeconomics of treating anxiety disorders, various studies of the cost, resource use and the economic outcomes of pharmacological treatment were examined. Numerous studies have been published that document how the excessive costs associated with anxiety disorders, especially panic disorder, result from a combination of factors including under-recognition and misdiagnosis of the problem by primary healthcare providers, high medical resource utilisation including unnecessary or inappropriate diagnostic tests and high levels of medical help-seeking behaviour by patients. Little information has been available on the economic effects of pharmacotherapy for anxiety disorders but recent studies have shown that selective serotonin re-uptake inhibitors (SSRIs) are associated with a shift in medical resource utilisation (lower rates of emergency department and laboratory visits) which can potentially result in decreased healthcare expenditures. Facilitating an increased awareness among primary healthcare providers of the anxiety disorders and utilising appropriate diagnostic and treatment strategies can benefit patients while providing more efficient and effective healthcare spending leading to an overall reduction in the burden of disease.
