to evaluate the effectiveness of cloud computing in hospital

today, growth, expansion, increased network speed and large-scale epidemic during recent years has been a shift in various aspects of human life, and the impact of advances in technology on the sciences, arts and business leads to emergence of new areas such as e-government, e-learning and e-health. the importance of knowledge and information in one hand and very high volume growth and the need to constantly update on the other hand leads to create new tools and solutions for processing and access to information. networks development and their functionality enhancement has a significant role in advance of this field. one of the new emerging ways is cloud computing system. cloud computing as a new it infrastructure and new web solutions could have significant benefits in providing electronic medical services. the use of this technology in e-health needs to consider several factors. the main objective of this study is to identify and rank the effective factors on the adoption of cloud computing in e-health. in this thesis, a model based on cloud computing is designed to integrate patient`s information and makes them available for patients and doctors. this comprehensive system significantly reduces processing time and service to the patient and also the display of patient records, including all the problems and diseases such as cardiovascular problems, allergies, lack of vitamins, etc., quality of care and also reduces the risk of diagnostic errors. in this system by using an intelligent module which protects evaluation and selection of proper emergency helps to patients and store patient`s information record by contacting cloud in common storage space. using this model, we can divide the space between the patient and doctor, and doctor become responsible from the beginning up to end of complete recovery.
