A study was conducted to examine the relations among patient-specific demographic characteristics, previous prescription costs and utilization, and subsequent prescription costs for a population of 55,677 Medicaid nursing home residents in Texas. Patient-specific factors, based on previous patient utilization and cost levels, exist within the Texas Medicaid nursing home population that may serve as predictors of subsequent prescription costs. Although some statistically significant relations exist between prescription costs and patient demographic factors such as age, sex, and location, these demographic factors are of little or no practical value in prediction of prescription costs for subsequent periods of time.
一项研究旨在调查得克萨斯州55677名医疗补助疗养院居民的特定患者人口统计学特征、既往处方费用和使用情况以及后续处方费用之间的关系。基于既往患者使用情况和费用水平的特定患者因素存在于得克萨斯州医疗补助疗养院人群中，这些因素可能作为后续处方费用的预测指标。尽管处方费用与年龄、性别和地点等患者人口统计学因素之间存在一些统计学上的显著关系，但这些人口统计学因素在预测后续时间段的处方费用方面几乎没有实际价值。
