摘　　要：目的评价实施电子病历是否能够提升医院的工作效率、医疗质量，降低患者医疗费用。方法从某院电子病历数据库中提取2004年7月～2012年6月共96个月普外科因乳腺癌住院并进行手术的患者数据，采用间断时间序列的方法分析实施电子病历前后住院天数、治愈率和人均费用的变化趋势。结果实施电子病历后，患者住院天数的斜率由上升趋势转变为下降趋势，较之前下降了0．065天／月；治愈率的斜率由略微下降变为上升趋势，较之前上升了0．013／月；人均费用在实施电子病历前后变化无统计学意义。结论电子病历的实施可降低乳腺癌患者的住院天数，小幅度提高患者治愈率，未发现电子病历的实施与人均费用有明显相关关系。Objective To evaluate whether the eleetronic medical record （EMIl） can improve work efficiency, enhance heahheare quality and reduce healthcare cost. Method Data of inpatients with breast cancer in the department of general surgery from July 2004 to June 2012 was extracted from hospital EMR database. Length of stay, cure rate and eost per patient between pre - and post - EMR were analyzed using an interrupted time series analysis. Result After the application of EMR, the slope of length of stay reversed from increasing to decreasing, and dropped hy 0. 065 days per month. The slope of cure rate reversed from slight decreasing to increasing, and rose by O. 013 per month. The cost per patient between pre - and post - EMIt changed insig-nificantly. Conclusion EMR ean shorten the length of stay of the inpatients with breast cancer and slightly increase the cure rate. Clear relationship between EMIl and the cost per patient was not found.
