to quantify the economic cost of polypharmacy in the elderly.
cost study design, made in two first-level medical units. The study was conducted in 131 older adult patients with polypharmacy, chronic degenerative disease and at least one medical visit per year. The sample was calculated using the formula of finite population averages. The cost of polypharmacy was assessed in medical consultation, medicine and pharmacy services. The evaluation of the medical cost included the number of visits per year for the same unit cost, the cost of medicine considered the amount of drug per year for the same unit cost, and the cost of the service pharmacy took into account the number of times the pharmacy occupies the unit cost of the same. The statistical analysis included means, percentages and confidence intervals.
in family practice the average annual cost is $1,263.26. In pharmacy the average annual cost is $229.91. The average time drug use is 4.37 months per year (95 % CI = 0.9-7.9), the annual average cost drugs is $708.00. Considering the three dimensions the annual cost of polypharmacy in the elderly is $2,201.17.
the cost of polypharmacy is high and represents a significant economic impact.
量化老年人多重用药的经济成本。
采用成本研究设计，在两个一级医疗单位开展。该研究纳入了131例患有多重用药、慢性退行性疾病且每年至少就诊一次的老年患者。样本使用有限总体均值公式计算。多重用药的成本在医疗咨询、药品及药房服务方面进行评估。医疗成本评估包括相同单位成本下每年的就诊次数，药品成本考虑相同单位成本下每年的药品用量，药房服务成本则考虑药房占用相同单位成本的次数。统计分析包括均值、百分比及置信区间。
在家庭医疗中，年均成本为1263.26美元。在药房方面，年均成本为229.91美元。每年平均用药时间为4.37个月（95%置信区间=0.9 - 7.9），年均药品成本为708.00美元。综合这三个维度，老年人多重用药的年均成本为2201.17美元。
多重用药成本高昂，具有显著的经济影响。
