Modeling of Factors Associated with the Duration of Inpatient Treatment of Residents of the Arctic Zone of the Arkhangelsk Region, Wounded from Limited-Damage Firearms

Summary. The aim of the study is to determine the average duration of inpatient treatment for victims who received injuries from limited-damage firearms (LLFWs) and the factors associated with these durations.

Materials and methods. A statistical study (in the form of the documentary observation) was carried out based on the records from 248 case histories of patients who received hospital care in Arkhangelsk and Severodvinsk (Arctic zone of the Arkhangelsk region) being wounded by NLW in 2005–2022. Simple (SLRA) and multiple linear regression analyses (MLRA) were used to detect factors and covariates associated with the duration of hospitalization of those patients.

Results of the study and their analysis. The study determined the average treatment times for victims in 2005–2014 and 2015–2022, as well as the average treatment times for victims: with a single wound, with two or more wounds; with a total severity of wounds, which was assessed using the CAP-P(OR) scale in points: less than 0.5 points, in the range of 0.5–0.99 points, and more than one point.

In addition, the average treatment times were determined for victims whose condition at the start of treatment was assessed as satisfactory, moderate, and severe.

It was concluded that the inpatient treatment times for victims with wounds from primary trauma depend mainly on the total severity of the wounds, determined using the CAP-P(OR) scale, and the severity of the victim’s condition upon hospitalization.
