The increasing number of geriatric dental patients and the development of treatment plans that require consideration of complex psychosocial, socioeconomic, and medical/medication factors necessitates a change in the traditional teaching of treatment planning. A computer-assisted instructional program was developed to simulate the dentist-geriatric patient interaction and to train students in clinical decision making for the geriatric patient. This study compared the effects of this program with a more traditional approach based on readings from the geriatric dentistry literature. Twenty third-year dental students were matched on grade point average and randomly assigned to the computer or literature-based groups. They were pretested using a clinical analogue of a geriatric patient and then instructed to use either the computer or literature-based educational units. The students were then post-tested on a second clinical analogue. Students performed similarly at pretest. At post-test, both the computer and literature-based subjects were found to have acquired significantly greater evaluation points, to make fewer errors, and to design more involved treatment plans than at pretest. Comparison of computer and literature-based subjects' performance revealed no significant main or interaction effects regarding type of educational unit used. Consistent nonsignificant trends were noted with the computer-based subjects out-performing literature-based subjects on each outcome variable. In addition, the computer-based subjects had more positive feelings about the educational unit than the literature-based subjects at a statistically significant level. These findings suggest that the computer program is an effective alternative method for developing clinical decision skills in students treating geriatric patients.(ABSTRACT TRUNCATED AT 250 WORDS)
老年牙科患者数量的不断增加以及治疗计划的制定需要考虑复杂的心理社会、社会经济和医学/药物因素,这使得传统的治疗计划教学必须做出改变。开发了一个计算机辅助教学程序,以模拟牙医与老年患者的互动,并培训学生针对老年患者进行临床决策。本研究将该程序的效果与基于老年牙科学文献阅读的更传统方法进行了比较。20名三年级牙科学生根据平均绩点进行匹配,并随机分配到计算机组或文献组。他们使用老年患者的临床模拟进行预测试,然后被指示使用计算机或基于文献的教育单元。然后,学生们在第二个临床模拟上进行后测试。学生们在预测试中的表现相似。在后测试中,发现基于计算机和基于文献的受试者都比预测试时获得了显著更多的评估分数,犯的错误更少,并且设计了更复杂的治疗计划。对基于计算机和基于文献的受试者的表现进行比较,结果显示在使用的教育单元类型方面没有显著的主效应或交互效应。在每个结果变量上,基于计算机的受试者表现优于基于文献的受试者,呈现出一致的不显著趋势。此外,基于计算机的受试者对教育单元的感受比基于文献的受试者在统计学上有更积极的显著差异。这些发现表明,计算机程序是培养治疗老年患者的学生临床决策技能的一种有效替代方法。(摘要截短至250字)
