Effects of establishing a trauma center on the mortality rate among injured pediatric patients in Japan.

ABSTRACT: INTRODUCTION:It remains unclear whether trauma centers are effective for the treatment of injured pediatric patients. The aim of this study was to evaluate children's mortality before and after the establishment a trauma center by using standard mortality ratios (SMR) and a modified observed-expected chart. METHODS:This was a single center, retrospective chart review study that included injured pediatric patients (age <16 years) who were transported to our trauma center by the emergency medical services from 2012 to 2016 in Japan. RESULTS:Our study included 143 subjects: 45 (31%) were preschoolers aged < 6 years, and 43 (30%) had an injury severity score (ISS) ? 16. After the trauma centers established, the number of patients increased (70% increase per month), as did the number of the patients with an ISS of 41-75. The percentage of indirect transportations was significantly higher in the trauma center than in the non-trauma center (49% vs. 28%; p < 0.05). The SMR was significantly lower in the trauma-center than in the non-trauma center (0.461 vs. 0.589; p < 0.05). The mean value of the modified observed-expected chart was significantly higher in the trauma-center than in the non-trauma center (4.6 vs. 2.3; p < 0.05). For the patients who were directly transferred to our center, the transfer distance was greater in the trauma-center than in the non-trauma center (6.8 vs. 6.2 km; p < 0.05). The time interval from hospital admission to initiation of computed tomography (15.5 vs. 33 minutes; p < 0.05) and to definitive care (44 vs. 64.5 minutes; p < 0.05) decreased in the after group compared to the non-trauma center. CONCLUSIONS:The results of our study revealed that the centralization of pediatric injured pediatric patients in trauma centers improved the mortality rate in this population in Japan.

Project description:IntroductionThe influence of reduced functional status has become increasingly relevant because of the gradual decline in mortality rate over the recent years. Nonetheless, only a few studies investigating the functional status of patients with trauma at hospital discharge have been conducted. This study aimed to identify the risk factors influencing the mortality rate in pediatric trauma survivors at a pediatric intensive care unit and analyze their functional status using the Functional Status Scale (FSS).MethodsA retrospective analysis was conducted at Shengjing Hospital of China Medical University. Children admitted to the pediatric intensive care unit between January 2015 and January 2020 who met the trauma diagnostic criteria were included. The FSS score and the Injury Severity Score (ISS) were recorded upon admission and discharge, respectively. Clinical data were compared between the survival and non-survival groups to identify the risk factors for poor prognosis. The risk factors for mortality were identified using multivariate and univariate analyses.ResultsA total of 246 children {59.8%, male; median [interquartile range (IQR)] age: 3 [1-7] years} were diagnosed with trauma (including head trauma, chest trauma, abdominal trauma, and extremity trauma). Of these patients, 207 were discharged, 11 dropped out mid-treatment, and 39 died (hospital mortality rate, 15.9%). Upon admission, the median FSS and trauma scores were 14 (IQR, 11-18) and 22 (IQR, 14-33) points, respectively. At discharge, the FSS score was 8 (IQR, 6-10) points. The patient clinical status improved with a ΔFSS score of -4 (IQR, -7, 0) points. At hospital discharge, 119 (48.3%), 47 (19.1%), 27 (11.0%), 12 (4.8%), and 2 (0.9%) survivors had good, mildly abnormal, moderately abnormal, severely abnormal, and very severely abnormal function, respectively. Reduced functional status in patients was categorized as follows: motor, 46.4%; feeding, 26.1%; sensory, 23.2%; mental, 18.4%; and communication, 17.9%. In the univariate analysis, ISS >25 points, shock, respiratory failure, and coma were independently associated with the mortality rate. Multivariate analysis revealed that the ISS was an independent risk factor for mortality.ConclusionThe mortality rate of patients with trauma was high. ISS was an independent risk factor for mortality. Mildly reduced functional status remained at discharge and was reported in nearly half of the discharged patients. Motor and feeding functions were the most severely impacted domains.
