Background: To provide health services for the increasing Ethiopian population therngovernment has increased the number of health facilities. To offer efficient and effectivernhealth services, however, patientsâ€™ medical record keeping or management system is veryrnimportant. In line with this, some developed countries have undertaken the transition tornElectronic Medical Records (EMR) system. Despite this fact, however, Ethiopia has notrngone far in this aspect, and most hospitals are still documenting on paper based medicalrnrecords, which is time consuming and sometimes even difficult to find. As a result, therernis time when physicians are treating patients without having patientsâ€™ backgroundrninformation of their past medical treatments. Therefore, it is very important and timely tornlook into why our hospitals are not using Electronic Medical Records (EMR). rnObjective: The general objective of the study was to assess factors that affectrnimplementation of EMR in government owned hospitals in Addis Ababa. rnMethods: A cross-sectional study design were used and health professionals and keyrninformants in ten government owned hospitals and the only two nongovernmentalrnhospitals that have fully implemented EMR, were assessed using questionnaire andrninterview on issues of health professionals attitude, budget, trained manpower,rnmanagement commitment, availability of technology and other related to EMRrnimplementation. A Simple random sampling technique was used to select healthrnprofessionals, depending on the population sizes of their hospitals and all key informantsrnwere selected purposively. Accordingly, a total of 399 health professionals and 12 keyrninformants from each hospital have participated in the study. Data analysis was donernusing chi-square test, mean, t-test and odds ratio. EPI-INFO version 3.3 and SPSSrnversion 11.0 was used to enter, clean, and analyze the data. rnResults - The majority 328 (92.1%) of health professionals in government hospitalsrnsupport implementation of EMR in their hospitals. Among the variables analyzed, rnrespondentsâ€™ age, sex, occupation, education status, having computer training, rnexperience, type of organization and level of communication between employees andrnmanagement were not found to significantly (p>0.05) affect health professionals attitude rnto support EMR implementation. Among government hospitals selected for this studyrnonly one hospital is in testing stage to implement EMR, while the remaining ninernhospitals have not implemented EMR. Among the factors analyzed, except lack ofrnbudget, all were not found to significantly affect the implementation of EMR. rnConclusions - From the findings of the study it is concluded that except lack of budget,rnother factors like employeesâ€™ attitude, management commitment, technology and lack ofrntrained manpower were not found to be significant factor to affect the implementation ofrnEMR in government hospitals. If budget is secured it is possible to implement EMR inrngovernment hospitals. rnRecommendations - Based on the findings of the study providing sufficient budget tornEMR implementation, hospitals to generate income, financial subsidy or donating tornimplement EMR, strengthening the existing programs on EMR implementation, effectiverntrainings and discussions with users and supporting domestic EMR software suppliers arernrecommended.
