STRATIFICATION OF THE EQUIVALENT FOR DENTAL TREATMENT COST ESTIMATION AMONG VICTIMS WITH MAXILLOFACIAL TRAUMA INJURIES OCCURRED AFTER ROAD-TRAFFIC ACCIDENTS

The article represents the results of data analytical processing considering the equivalent for dental treatment cost estimation among victims of traffic accidents with dental and maxillofacial injuries, and analyzes the objective association level of this criterion with the parameters of the approaches used for expert assessment of maxillofacial trauma injuries. The aim of the study is to analyze the equivalent for dental treatment cost values among victims of traffic accidents with dental and maxillofacial trauma injuries, and to establish an objective level of associations of this criterion with the parameters of the approaches used for expert assessment of maxillofacial trauma injuries. Material and methods. The design of the work included analytical processing of data obtained from previously conducted studies of retrospective and prospective nature, related to the economic component of patients rehabilitation due to the maxillofacial injuries occurred after road traffic accidents. The studied parameters were: the cost of treatment, duration of hospitalization, the criterion used to assess traumatic injuries of the maxillofacial region, correlation values relating trauma characteristics with the final cost of treatment and duration of hospitalization, statistical reliability of the relationships between the studied indicators of previously conducted research. Research methods: analytical, prognostic assessment, regression analysis. Scientific research. "Expert evaluation of advanced dental treatment and rehabilitation technologies".

An increase in the number of cases of road accident-related injuries is noted in many economically developed countries; on the other hand, the tendency to decrease the frequency of occurrence of criminal, domestic and industrial injuries is also specific for them. In developing countries and countries with a transition economy, the pattern of the relationship of the number of injuries depending on their genesis, including injuries of the maxillofacial region, is the reverse of the above, but with the preservation of the predominance among the main cases of domestic and criminal injuries and injuries as a result of more expensive - transport events. In addition, the results of a systematic review and meta-analysis proved that road accidents are the main cause of maxillofacial injuries among children and adolescents (34%; 95%). Conclusions. Current approaches used for expert severity assessment of the maxillofacial trauma injuries occurred after road accidents characterized by limited opportunities to predict and stratify the costs associated with the necessary future dental treatment of victims, but provide a sufficient level of objectification of functional and structural disorders. The increase of the expert severity assessment criteria of maxillofacial trauma injuries, in particular FISS and MFISS scores, is associated with an increase in the cost of appropriate comprehensive treatment and the potentially required duration of hospitalization, but these associations are characterized by uneven patterns of statistical dependences, and an increase in FISS and MFISS indicators beyond certain limit levels provokes a sharp advance in the cost of treatment due to the need for a longer hospitalization of the patient.
