Determinants of health expenditures during the last year of life of the Mexican population aged 50 or over.

During the last year of life of the elderly health deteriorates the most, thus becoming the period of time when needs of medical services, personal care requirements and related costs are at highest. Using the Mexican Health and Aging Study, differences by sex in the determinants for out-of-pocket health expenditures during the last year of life of people 50 and over are discussed. Three levels of out-of-pocket expenses disbursement are contemplated: none, medium-low, and high. Controlling by sociodemographic variables, findings suggest that the number of hospital nights is the main determinant of health expenses, even above those related to diseases that are regarded as main causes of death. This fact impacts both out-of-pocket expences and the costs for medical institution. It is another issue in the over-hauling of the public health system.
