Between July 1973 and February 1976, clinicians in the DMH Institutions of a midwestern state received regular, computer generated information about those of their patients who had been prescribed more than 4 psychotropic drugs during the preceding month. The effect of this feedback on prescribing habits was assessed, using information derived from monthly itemized billing record returns. The results showed that, while a highly significant reduction in polypharmacy did take place, it antedated the circulation of the specific feedback, coinciding instead with the discussions between the computer project staff and institution superintendents at the planning stage of the project.
1973年7月至1976年2月期间，美国中西部某州精神卫生机构的临床医生定期收到计算机生成的信息，这些信息涉及前一个月内被开具4种以上精神药物处方的患者。利用每月逐项计费记录回报得出的信息，评估了这种反馈对处方习惯的影响。结果显示，虽然联合用药确实有显著减少，但这一现象早于特定反馈的传播，而是与计算机项目工作人员和机构负责人在项目规划阶段的讨论同时出现。
