en اورژانس Emergency مروری Review <div style="text-align: justify;">As public safety answering points (PSAPs) have become the elementary contact point between clients and rescue service providers, the planning of the call center has become a key task for administrators. Connect call centers accelerate dispatch center performance, particularly during an overloaded period. The efficient dispatch of emergency medical services and prompt response to urgent requests could be achieved with their help. This study aims to explore national and international experiences to identify PSAP models and their key dimensions. In this research, Arksey and O&rsquo;Malley&rsquo;s five-step framework will be followed. Additionally, incorporating the PRISMA extension into this scoping review will allow us to extensively investigate the available literature on PSAP models up until the year 2024. For this purpose, a comprehensive review will be conducted using PubMed, Web of Science, and Scopus to examine officially published reports. In addition, grey literature will be sourced from Google Scholar, the World Health Organization (WHO) website, and relevant regional offices.&nbsp;</div> Public safety answering point (PSAP), Emergency call, Emergency medical dispatch 47 52 http://hdq.uswr.ac.ir/browse.php?a_code=A-10-588-1&slc_lang=en&sid=1 Morteza Mortazavi mor.mortazavi@uswr.ac.ir 0000-0002-4919-7401 No Health in Emergency and Disaster Research Center, Social Health Research Institute, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran.
