Through this research, the referral cooperation hospital choice has been studied to rationalize the allocation of healthcare assets better and enhance the efficacy of resource utilization. As choosing hospitals to work within a collaborative referral arrangement is a crucial step in the patient-referral process. Care quality, service availability, location, insurance coverage, cost, communication and coordination, and cultural competence are just a few variables considered when choosing a referral cooperative hospital. A referral cooperative hospital is chosen after careful consideration of these aspects to guarantee that patients will get the kind of detailed treatment that is appropriate for their condition. The concept of multi-criteria decision-making (MCDM) is used due to various criteria. The VIKOR method is the MCDM method used in this paper to rank the referral cooperation hospitals. According to the proposed framework in this research; the VIKOR method is integrated with the single-valued Neutrosophic set to overcome uncertain information. The single-valued Neutrosophic VIKOR method is applied to a case study in Egypt within eight hospitals according to eleven criteria. We reached that the quality of care is the best criterion from the eleven criteria used.
