title: An analysis of predictors of prescription drug costs among Medicaid nursing home residents in Texas.
abstract: 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.
