眼科PACS系统用于研究生教学的效果评估

摘要

Objective To construct subsystem of picture archiving and communicating system (PACS) based on video database of ophthalmology and to evaluate on effectiveness of applying PACS system in postgraduate teaching.Methods PACS subsystem were constructed by collecting audiovisual materials of ophthalmology surgery videos,retinal photography,B-ultrasonography,OCT,UBM of patients.A total of 24 postgraduates were divided into control group (n =12) and experimental group (n=12) by random number table.Students in control group was taught by traditional cases,books and literature while those in experimental by network teaching from PACS subsystem.Two teaching methods were assessed subjectively and objectively.Objective indicators including ophthalmology examination results,operational skill ratings and paper reviewing results as well as subjective indicators including efficiency to accept the knowledge,satisfaction degree of teaching,influencing degree of papers were employed to assess the effectiveness of the two teaching methods.Independent samples t-test and twosample rank sum test were used for statistical analysis,P ＜ 0.05 was considered statistically significant.Results Students in experimental group done better in operation scores and in the assessment of the efficiency of knowledge accepting,satisfaction of teaching and papers effect than control group(P =0.000、0.000、0.000、0.003).The two groups had no significant difference in professional exam achievements and paper review scores (P =0.625、0.354).Conclusions PACS subsystem based on video database of ophthalmology are benefit for postgraduate teaching.%目的 以眼科影音网库为基础构建影像存档和传输系统(picture archiving and communicating system,PACS)的子系统,评估将该系统应用于研究生教学的效果.方法 收集整理眼科手术录像、B超、OCT、UBM、眼底照相等影音资料,以此为基础构建PACS子系统.将24名眼科硕士研究生采用随机数字表法分为对照组和实验组,每组12名.对照组采用传统的病例、图书、文献示教的方式授课,实验组采用PACS子系统网络教学.从眼科学考试、操作技能评分、论文评阅等客观成绩以及接受知识效率、教学满意度、对论文影响度等主观评价两方面评估两种教学方法的效果.采用独立样本的t检验以及两样本等级秩和检验进行统计学分析,P＜0.05表示有统计学意义.结果 实验组学生在操作技能评分、接受知识效率、教学满意度、对论文影响度方面的评估结果均优于对照组(P值分别为0.000、0.000、0.000、0.003),而在专业考试成绩及论文评阅成绩方面两组差异无统计学意义(P值分别为0.625、0.354).结论 以眼科影音网库为基础构建的PACS子系统应用于研究生教学的效果较好,在充分开发利用教学资源的同时利于教学质量的提高.
