An earlier study showed that the prothrombin time determination is overutilized as a routine admission laboratory test. In the present study the investigator evaluated the effectiveness of an educational program in decreasing utilization of the prothrombin time determination by house staff physicians at a teaching hospital. Six months after the educational program, use of the prothrombin time determination as a routine admission test had decreased significantly from 87 percent to 55 percent. Eighteen months after the educational program, the use of this test by the study group had returned to initial levels. These results emphasize the need to measure the long-term outcome of educational programs aimed at modifying the clinical behavior of physicians and to institute follow-up programs to ensure that an educational effort will have a lasting effect.
一项早期研究表明，凝血酶原时间测定作为一项常规入院实验室检查被过度使用。在本研究中，研究者评估了一项教育计划在降低教学医院住院医师对凝血酶原时间测定的使用方面的有效性。教育计划实施六个月后，凝血酶原时间测定作为常规入院检查的使用率从87%显著降至55%。教育计划实施十八个月后，研究组对该检查的使用已恢复到初始水平。这些结果强调了有必要衡量旨在改变医生临床行为的教育计划的长期效果，并设立后续计划以确保教育努力能产生持久影响。
