This study aimed to compare the cost of manpower for environmental health services in public health centers in the current situation and scenarios based on local needs.<br> Methods: A financial model including fixed and variable costs in providing human resources was used. Human resources costs in the current situation and scenarios based on the allocation of human resources considering local needs were analyzed and compared. The financial situation in the studied scenarios was analyzed using the Monte Carlo simulation.<br> Results: The workforce capacity was 25.38 to 80.06% less than local demands. Also, in 25% of the studied rural health centers, the workforce capacity was 13.8 to 39.03% less than local demands. In addition, in 75% of the rural health centers, the capacity of the environmental health workforce was 13-138% higher than local demands. Based on the traditional human resource support model, increasing the capacity of the environmental health workforce in the studied area would require hiring equal to 84% of the current workforce capacity, which would increase human resource management costs by 60%. However, applying a proportional distribution model of the environmental health workforce led to a 14.42% reduction in human resource costs.<br> Conclusion: Proportional distribution of the health workforce based on local demands is a necessity in human resource management to prevent occupational consequences such as burnout and administrative costs.</div> Healthcare service, Human resource, Health management, Health economics 1 9 http://ehemj.com/browse.php?a_code=A-10-1-435&slc_lang=en&sid=1 Navid Alinejad navidalinejad045@gmail.com 100319475328460021675 100319475328460021675 No Department of Public Health, School of Health, Fasa University of Medical Sciences, Fasa, Iran Lida Rafati lida.rafati87@gmail.com 100319475328460021676 100319475328460021676 No Deputy of Health, Hamadan University of Medical Sciences, Hamadan, Iran Ramin Hayati ramin.hayati202@gmail.com 100319475328460021677 100319475328460021677 No Department of Public Health, School of Health, Fasa University of Medical Sciences, Fasa, Iran Mohammad Ansarizadeh mansarizadeh@yahoo.com 100319475328460021678 100319475328460021678 No Department of Environmental Health Engineering, Mamasani Higher Education Complex for Health, Shiraz University of Medical Sciences, Shiraz, Iran Masoud Yousefi masoud.yousefi@yahoo.com 100319475328460021679 100319475328460021679 No Department of Environmental Health Engineering, Mamasani Higher Education Complex for Health, Shiraz University of Medical Sciences, Shiraz, Iran Hamed Mohammadi mohammadih2@trjums.ac.ir 100319475328460021680 100319475328460021680 Yes Correspondence to: Department of Environmental Health, Torbat Jam Faculty of Medical Sciences, Torbat Jam, Iran Javad Torkashvand javad.torkashvand@yahoo.com 100319475328460021681 100319475328460021681 No Health System Research Committee, Hamadan University of Medical Sciences, Hamadan, Iran
