@article{ author = {YousefiZenouz, R and SajjadiKhosraghi, F}, title = {Risk Assessment in the Implementation of Hospital Information System: A Case Study}, abstract ={Introduction: Hospital information systems play an important role in improving coordination between different sectors of a hospital and increasing the efficiency of its managerial processes. Despite great advantages of these systems, many hospitals have encountered some obstacles at the implementation stage that deviate the systems from their primary goals. These events caused the hospital information systems to fail. The aim of this paper is to present a model for identification of these events and categorize them and finally prioritize them in order to manage or hinder their occurrence. Methods: Firstly, by reviewing the related literature, we identified the risks that possibly can occur in this area. After extracting the risks, their consequences have been quantified by means of expert judgment. Experts were selected from Milad hospital. Then the risks' priorities have been determined by applying fuzzy analytic hierarchy process. The reliability and the validity of the related questionnaire have been determined Results: Between four identified factors, the highest scores were related to the managerial factors with the weight of 0.84 while the organizational factors gained the lowest score by the weight of 0.01. After multiplying the probability of each risk factor to its consequence, the priorities changed. Conclusion: Employing qualified personnel in the field of health information systems, providing necessary trainings to them and preparing technical infrastructure before the implementation of the system along with the assignment of the required resources, and paying special attention to interpersonal relationships are very crucial in the reduction of failure risk of hospital information system implementation project.}, Keywords = {Hospital information systems, risk assessment, fuzzy analytic hierarchy process (FAHP) 1. استادیار گروه مدیریت فناوری اطلاعات, ؛ نویسنده مسئول (reza.zenouz@gmail.com) 2. دانشجوی کارشناسی ارش}, volume = {20}, Number = {67}, pages = {7-23}, publisher = {Iran University of Medical Sciences}, url = {http://jha.iums.ac.ir/article-1-2072-en.html}, eprint = {http://jha.iums.ac.ir/article-1-2072-en.pdf}, journal = {Journal of Health Administration}, issn = {2008-1200}, eissn = {2008-1219}, year = {2017} } @article{ author = {Jahani, J and Rezaeenoor, M and Mahdavi, M and Hadavandi, E}, title = {Prediction of diabetes by Neural Network}, abstract ={Introduction: Meta-heuristic and combined algorithms have a great capability in modelling medical decision making. This study used neural networks in order to predict Type 2 Diabetes (T2D) among high risk individuals. Methods: This study was   an applied research. Data from 545 individuals (diabetic and non-diabetic), in Diabetes Clinic of Hamedan University of Medical Sciences, were used to develop predictive diabetes models. Memetic algorithms which are a combination of genetic algorithm (GA), local search algorithm, and neural networks were applied to update weights and improve predictive accuracy of neural network models. In the first step, optimum parameters for neural networks such as momentum rate, transfer functions, and error functions were examined through trial and error and other studies. Results: The preliminary analysis showed that the accuracy of neural networks was 88 percent. The use of memetic algorithm improved its accuracy to 93.2 percent. Among models, regression model had the least accuracy. For the memetic algorithm model the amount of sensitivity, specificity, positive predictive value, negative predictive value, and area under the curve were 96.2, 95.3, 93.8, 92.4, and 0.958, respectively. These parameters for GA were 98.0, 84.8, 88.6, 98.2, and 0.952 and for the logistic regression model were 95.6, 84.5, 94.7, 87.0, and 0.916, respectively. Conclusions: Models developed by neural networks have a higher predictive accuracy than the regression model. The results of this study can contribute to risk management and planning of health services by providing healthcare decision makers with more accurate predictive models based on clinical and life style characteristics of individuals.}, Keywords = {Diabetes, Decision Support Techniques, Neural network, Genetic Algorithms, Memetic algorithm }, volume = {20}, Number = {67}, pages = {24-35}, publisher = {Iran University of Medical Sciences}, url = {http://jha.iums.ac.ir/article-1-2091-en.html}, eprint = {http://jha.iums.ac.ir/article-1-2091-en.pdf}, journal = {Journal of Health Administration}, issn = {2008-1200}, eissn = {2008-1219}, year = {2017} } @article{ author = {Sadeghpour, M and KayzouriAH, AH and Ferdosimakan, A}, title = {Applying Method of Data Envelopment Analysis in the Assessment of Hospital Information Systems}, abstract ={Introduction: Hospital Information System (HIS) is universal software for integrating information of patients, with the aim of improving the quality and reducing the costs. So, given the importance of these systems, continuous evaluation of hospital information is essential. The main goal of this study is to find and select pattern(s) suited for evaluating efficiency of these systems. Methods: In this study, we evaluated the efficacy by novel multidimensional Data Envelopment Analysis (DEA) methods. Statistical population included 28 of 34 hospitals supported by Mashhad University of Medical Sciences using hospital information systems. Results: The estimated scores of different models showed that various methods are different from each other, as the average and standard deviation of scores of the superior performance model and the conventional model were 0.2656 ± 0.74 and 0.0541 ± 0.04 respectively. However, despite this difference in scores, linear relationship between all the relationships (except for one relationship) was significant (p-value<0.05) and there was a remarkable correlation between some of these methods. Although the objective functions of different methods had some advantages, however, using efficiency mean scores pattern in evaluating the efficiency of hospital information systems is considered an appropriate approach. Conclusion: Based on theoretical justification and practical interpretation of the results and to cut the complexity in applying the operational model of performance evaluation, the superior performance method could be introduced as the preferred method to evaluate hospital information systems.}, Keywords = {Data envelopment analysis, evaluation, hospital information systems, Mashhad University of Medical Sciences }, volume = {20}, Number = {67}, pages = {36-49}, publisher = {Iran University of Medical Sciences}, url = {http://jha.iums.ac.ir/article-1-2115-en.html}, eprint = {http://jha.iums.ac.ir/article-1-2115-en.pdf}, journal = {Journal of Health Administration}, issn = {2008-1200}, eissn = {2008-1219}, year = {2017} } @article{ author = {JafariSirizi, M and Seyedin, S and Aghlmand, S and SeyedMahmodi, M}, title = {Performance Indicators of Emergency Departments Following the Implementation of Specialist Residency Program under the Health Sector Evolution Plan in Public Hospitals of West Azerbaijan Province}, abstract ={Introduction: It seems permanent presence of resident specialists affects the performance indicators of emergency department (ED).

Therefore, this paper aimed to analyze the impact of these conditions on different levels of health expenditures of households in Iran. Methods: In this applied study, an econometric model, Ordered Probit, was used. The related data on household expenditure and income in 2014 were collected from Statistical Center of Iran by means of a questionnaire. The population consisted of 23573 Iranian households living in different areas in Iran. Estimation of results and Data analysis was performed using STATA 14.0. Result: According to the findings, householder education level, age, gender (male householders), per capita income, size of household, and health insurance coverage were positively related to household health expenditure. There was also a negative marginal effects for above variables in group one of dependent variable. It means that households with better socio-economic situation, have a low tendency for low health expenditures which again becomes positive for higher health expenditures. Moreover, households with rural insurance, social security insurance, complementary insurance and medical treatment insurance paid lower health expenditures, respectively. Conclusion: Households with better socio-economic status, spend more on their health care. Since households pay differently for different health insurances, it is recommended that government provide a fair basic insurance package of the same quality of services to cover all households, a package which is not affected by economic inequality.}, Keywords = {Health Expenditures, Socioeconomic Status of Household, Health Insurance, Ordered Probit Model }, volume = {20}, Number = {67}, pages = {89-98}, publisher = {Iran University of Medical Sciences}, url = {http://jha.iums.ac.ir/article-1-2170-en.html}, eprint = {http://jha.iums.ac.ir/article-1-2170-en.pdf}, journal = {Journal of Health Administration}, issn = {2008-1200}, eissn = {2008-1219}, year = {2017} } @article{ author = {Ashoori, M}, title = {A Model to Predict Hemodialysis Buffer Type Using Data Mining Techniques}, abstract ={Introduction: Inadequate dialysis for patients' kidneys as a mortality risk necessitates the presence of a pattern to assist staff in dialysate part to provide the proper services for dialysis patients and also the proper management of their treatment.
