Background: The hospital is an important element in the new public health. The health in the populations requires access to the medical and hospital services as well as preventive care and a healthy environment. This study attempts to review the important factors to be considered in the hospital sites selected and design in the urban, regional and country levels. Finally, suggestions have exhibited to the hospital sites selected and design for its optimum and efficiency. It's also suggests proposals for appropriate site selected and design of hospitals for optimum efficiency.
Materials & Methods: This is a review article which documentary method and Internet search have been employed.
Results: What principles do you use to decide on the location and layout of a new or expanded site selection? What information do you need to consider before selecting a site location? How do you maximize inherently safer design with minimal impact on the cost and schedule? How do you manage sitting issues when limited space is available? How do you address security concerns in a new site? These questions are considered cases in paper to attempt to answer it.
Conclusion: To determine the feasibility of the project, the first consideration in the survey is to study the character, needs and possibilities of the community which the hospital is going to serve. The hospital facilities in the region should be studied in terms of:
• Population of the region
• Quality and number of hospitals
• Patient and disease pattern
• Cost of investigation and treatment
• Physical and Environmental characteristics of the site
This study considers the specific problems of creating a well distributed network of hospitals that deliver its services to the target population in minimal time, pollution and cost. The study has showed that if these criteria considered, it would assessed the extent to which authorities of hospital planning and administration have utilized in the planning.

  Background: In Iran, the rapid growth of urbanization is in a way that it fits into the appropriate location for urban spaces are not switching. The main consequence of this is failure of service delivery and service system to citizens. One of the most important public services that hospitals provide most of the citizens' health. The purpose of this study, “Optimal locating of hospitals in region 7 in Tehran city”.

  Material and methods: This research is descriptive - analytical study has been done. For collecting information and data is used field studies and According to information obtained, To review the study area in terms of access to communication road, green space, away from industrial centers, military, and the fault, as well as for weighting the criteria, is used the AHP model. Then, using a decision model of TOPSIS in GIS software, valuation of criteria has been studied and appropriate maps is prepared, finally map that represents the best location for the construction of hospitals in this area is extracted.

  Results: with combination and overlaying of data layers, the final map was obtained and determined that the northeastern section (Cross Resalat Street and cabli), central (martyr Motahari streets and Miremad) and southeast (Bakhshi fard and part of Damavand street) in district 7 are have priority and more points to construct hospitals.

  Conclusion : System of Multi Criteria Decision Making (MCDM) with GIS can be used as effective tool in site selection of hospitals. Being located of hospitals, near to green spaces and comunication road and its distance from the industrial and military areas as well as the fault, capability of this model in this study is prove.
