Estimating spending for prescription drugs has become increasingly difficult over the past 15 years as extensive changes have taken place within the retail prescription drug industry. Expenditures for prescription drugs in retail outlets grew rapidly during the 1980s and early 1990s. New retail outlets emerged and existing sites lost market share. New mechanisms for reimbursing drug purchases led to the flow of rebates between manufacturers and insurers, bypassing retailers. These and other major industry changes required the development of new estimating methodologies for tracking prescription drug expenditures within the National Health Accounts (NHA).
在过去15年里，随着零售处方药行业发生了广泛变化，估算处方药支出变得越来越困难。20世纪80年代和90年代初，零售药店的处方药支出迅速增长。新的零售药店不断涌现，现有药店的市场份额不断流失。新的药品购买报销机制导致制造商和保险公司之间出现回扣流动，绕过了零售商。这些以及其他主要行业变化要求开发新的估算方法，以跟踪国民健康账户（NHA）中的处方药支出。
