Intense care beds, in particular, are more important. The present study was conducted to design and validate a measuring tool for the factors affecting the distribution of hospitals&#39; intensive care beds in Iran.<br> <strong>&nbsp;&nbsp; Methods:</strong> In this mixed method study, first, all known factors affecting the distribution of hospitals&#39; intensive care beds were extracted by reviewing related literature. Then, all 60 confirmed items were categorized into different dimensions. Face validity and content validity of the questionnaire was done by 20 medical experts through qualitative and quantitative methods. Validity and reliability indices, content validity index (CVI), content validity ratio (CVR), and Cronbach&#39;s alpha were measured. SPSS software were used for data analysis and significance level was set at less than .05.<br> &nbsp;&nbsp; <strong>Results:</strong> From the 60 suggested items, 34 were confirmed by the expert panels and all items had CVR and CVI scores higher than 0.83 and 0.81, respectively. CVR and CVI for all 34 items were 0.88 and 0.89, respectively. Also, Cronbach&#39;s alpha coefficient (0.75) indicated a suitable internal consistency. The value of S-CVI / Ave was also calculated to be 0.92.<br> &nbsp;&nbsp; <strong>Conclusion: </strong>In this study, a valid tool was designed to identify the factors affecting the distribution of hospitals&#39; intensive care beds. This tool consists of 6 dimensions: demographic, geographic, economic, sociopolitical, organizational, and constructional.&nbsp;<br> &nbsp;<br> &nbsp; Intensive care beds, Rationing intensive care beds, Distribution of beds 481 485 http://mjiri.iums.ac.ir/browse.php?a_code=A-10-5061-1&slc_lang=en&sid=1 Nahid Farrokhyar farokhyar@yahoo.com 200319475328460062514 200319475328460062514 No Department of Health Services Management, North Tehran Branch, Islamic Azad University, Tehran, Iran Khalil Alimohammadzadeh dr_khalil_amz@yahoo.com 200319475328460062515 200319475328460062515 Yes Department of Health Services Management, North Tehran Branch & Health Economics Policy Research Center, Tehran Medical Sciences Branch, Islamic Azad University, Tehran, Iran Ali Maher dralimaher@gmail.com 200319475328460062516 200319475328460062516 No Department of Health Policy, School of Management and Medical Education, Shahid Beheshti University of Medical Sciences, Tehran, Iran Seyed Mojtaba Hosseini hosseinisch@yahoo.com 200319475328460062517 200319475328460062517 No Department of Health Services Management, North Tehran Branch, Islamic Azad University, Tehran, Iran Mohammadkarim Bahadori bahadori_57@yahoo.com 200319475328460062518 200319475328460062518 No Health Management Research Center, Baqiyatallah University of Medical Sciences, Tehran, Iran
