Objective This study investigated the status and evaluated factors associated with knowledge and attitudes regarding pediatric concussions among Korean parents of children aged 6 to 18 years. Methods A cross-sectional online survey was employed to collect data from a panel of parents in Korea in 2023. To assess knowledge and attitudes regarding concussions, participants completed a validated questionnaire. The outcome variables of total knowledge score (range, 0–30) and total attitude score (range, 7–49) were categorized into tertiles. We conducted multivariable ordinal logistic regression analyses with participants and their children based on demographic information and characteristics as covariates. Results A total of 260 parents responded to the survey and demonstrated moderate concussion-related knowledge (median total score, 21; interquartile range [IQR], 18–22.5). The respondents exhibited favorable attitudes toward concussions (median total score, 39; IQR, 34–43), except the attitude of the importance of reporting concussion. Multivariable ordinal regression analysis for outcomes revealed only career of healthcare provider (adjusted odds ratio, 3.15; 95% confidence interval, 1.13–8.75) to be associated with parental concussion-related knowledge. No factors exhibited a significant association with parental attitudes toward concussions. Conclusion Our results confirmed the knowledge-attitude gap regarding pediatric concussions among Korean parents. Effective strategies are warranted to improve parental knowledge and attitudes.

Objective To investigate variations in the effects of prehospital advanced airway management (AAM) on outcomes of out-of-hospital cardiac arrest (OHCA) patients according to regional emergency medical service (EMS) systems in four Asian cities.
Methods We enrolled adult patients with EMS-treated OHCA of presumed cardiac origin between 2012 and 2014 from Osaka (Japan), Seoul (Republic of Korea), Singapore (Singapore), and Taipei (Taiwan). The main exposure variable was prehospital AAM. The primary endpoint was neurological recovery. We compared outcomes between the prehospital AAM and non-AAM groups using multivariable logistic regression with an interaction term between prehospital AAM and the four Asian cities.
Results A total of 16,510 patients were included in the final analyses. The rates of prehospital AAM varied among Osaka, Seoul, Singapore, and Taipei (65.0%, 19.2%, 84.9%, and 34.1%, respectively). The non-AAM group showed better outcomes than the AAM group (adjusted odds ratio [aOR] for neurological recovery 0.30; 95% confidence interval [CI], 0.24–0.38]). In the interaction model for neurological recovery, the aORs for AAM in Osaka and Singapore were 0.12 (95% CI, 0.06–0.26) and 0.21 (95% CI, 0.16–0.28), respectively. In Seoul and Taipei, the association between prehospital AAM and neurological recovery was not significant (aOR 0.58 [95% CI, 0.31–1.10] and 0.79 [95% CI, 0.52–1.20], respectively). The interaction between prehospital AAM and region was significant (P=0.01).
Conclusion The effects of prehospital AAM on outcomes of OHCA patients differed according to regional variability in the EMS systems.

Objective We aimed to develop an International Classification of Diseases (ICD) 10th edition injury code-based disability-adjusted life year (DALY) to measure the burden of specific injuries.
Methods Three independent panels used novel methods to score disability weights (DWs) of 130 indicator codes sampled from 1,284 ICD injury codes. The DWs were interpolated into the remaining injury codes (n=1,154) to estimate DWs for all ICD injury codes. The reliability of the estimated DWs was evaluated using the test-retest method. We calculated ICD-DALYs for individual injury episodes using the DWs from the Korean National Hospital Discharge Injury Survey (HDIS, n=23,160 of 2004) database and compared them with DALY based on a global burden of disease study (GBD-DALY) regarding validation, correlation, and agreement for 32 injury categories.
Results Using 130 ICD 10th edition injury indicator codes, three panels determined the DWs using the highest reliability (person trade-off 1, Spearman r=0.724, 0.788, and 0.875 for the three panel groups). The test-retest results for the reliability were excellent (Spearman r=0.932) (P<0.001). The HDIS database revealed injury burden (years) as follows: GBD-DALY (138,548), GBD-years of life disabled (130,481), and GBD-years of life lost (8,117) versus ICD-DALY (262,246), ICD-years of life disabled (255,710), and ICD-years of life lost (6,537), respectively. Spearman’s correlation coefficient of the DALYs between the two methods was 0.759 (P<0.001), and the Bland-Altman test displayed an acceptable agreement, with exception of two categories among 32 injury groups.
Conclusion The ICD-DALY was developed to calculate the burden of injury for all injury codes and was validated with the GBD-DALY. The ICD-DALY was higher than the GBD-DALY but showed acceptable agreement.
