Population aging has a direct impact on the increasing demand of health services and on medical care costs. The objective was to carry out a cost analysis of health care costs in older adults in a regional general hospital of the Instituto Mexicano del Seguro Social.
A calculation of the costs was done based on a retrospective collection of health care data. Unit prices were used to estimate costs. These were reported in 2016 Mexican pesos. A cost analysis was carried out by means of a regression model. Explanatory variables were sex, age and comorbidity level, the latter measured by using the Charlson index.
The average cost of all the 509 patients was 34 769 Mexican pesos (SD = 2869 pesos). Age variable explains the costs; however, sex and comorbidity variables were not significant. Cost predictions with the statistical model show differences mainly by age. In the case of females, the model predicts greater costs compared with those of males. Costs for older adults of 85 years or more were greater than those for the group of younger people (75-84).
The hospitalization costs estimated are high and they differ according to the age group. We suggest to make further research in order to know the factors associated with high hospital costs for this age group.
人口老龄化对卫生服务需求的增加以及医疗费用产生直接影响。目的是对墨西哥社会保障局一家地区综合医院的老年人医疗保健费用进行成本分析。
基于对医疗保健数据的回顾性收集进行成本计算。使用单价来估算成本。这些成本以2016年墨西哥比索报告。通过回归模型进行成本分析。解释变量为性别、年龄和共病水平，后者使用查尔森指数进行测量。
509名患者的平均成本为34769墨西哥比索（标准差 = 2869比索）。年龄变量可解释成本；然而，性别和共病变量不显著。统计模型的成本预测主要显示出年龄差异。在女性中，该模型预测的成本高于男性。85岁及以上老年人的成本高于较年轻人群（75 - 84岁）。
估计的住院成本很高，并且因年龄组而异。我们建议进一步开展研究，以了解与该年龄组高住院成本相关的因素。
