Outline Background Methodology Result Discussion Conclusion Slide 2

Background Airway Management Slide 3

Background (world) Deaths(1,000) in 2011 Slide 4 Un intentional Injuries WHO,2011

Background (Thailand) New Year Normally number/day IS;153,237, Dead 6,928 Case Fatality Rate=4.52% IS: Road Traffic Accident,Khon Kaen Slide 5 Deaths Rate Per 100,000 Population

Background (Pre-hospital care) Emergency Medical Institute severity patients received the out-hospital care by EMS>>>> increased & up-rise in the future 82,895 times (8.73%) to 99,112 (9.75%) KhonKaen Province (Injury Surveillance : IS) severe injury patients almost referred to hospital by EMS 36.11% relatve 61.19% and non registered organization 0.4%(2009) Slide 6

Background (Pre-hospital care) while caring to hospital by EMS The pre-hospital airway management 43.37% no medical care but needed 1.91% improperly care referred to the upper level The pre-hospital airway management Improperly care 2.26% No medical care but needed 5.75% * Standard setting: %not more than 5% of all injury case who need medical care Slide 7

Los Angeles study ( ) Pre-hospital endotracheal intubation in isolated, moderate to severe TBI patients is associated with a nearly 5-fold increase in mortality. Cudnik,et al. [2010] After adjusting for these differences, use of pre-hospital RSI-ETI was not associated with improved survival. Prior Studies (The pre-hospital airway management ) Slide 8

Gabs of Knowledge ignored to shown the test of association or measurement in Thailand this study purpose to investigate the effect of pre-hospital airway management on the mortality Slide 9

Objective To investigate the effect of pre-hospital airway management on mortality of unintentional Injured patients in Khon Kaen Hospital, Thailand. Research Question Dose the pre-hospital airway management affect to mortality among unintentional Injured patients? Slide 10

Study design Cross-sectional analytical study Based on the National Injury Surveillance Records From January to December 2012 Dependent Variable: Mortality Independent Variable : Pre-hospital airway management Materials and Methods Slide 11

Materials and Methods Statistical analysis Descriptive statistics Bivariate analysis (crude OR,95%CI,p-value) Multivariable analysis (adj OR,95%CI,p- value) potential confounders p < 0.05 Setting: Khon Kaen Province Slide 12

Discussion pre-hospital inappropriate airway management was associated with significantly increased mortality (ORc 5.78, 95%CI: 2.14 to15.59; p=0.004) Relative Eyewitness EMS Non registered organization Different skill Slide 20

Discussion Then….. (ORadj 3.42, 95% CI: 0.42 to27.91, p< 0.001) Los Angeles study After adjusting for possible confounding factors, multivariable logistic regression analysis demonstrated that PHI was independently associated with increased mortality (AOR 5, 95% CI: 1.7–13.7, P (0.004) Cudnik,et al. in the propensity-adjusted model, there was no statistical difference in mortality between the two groups (odds ratio 0.74, 95% confidence interval 0.52–1.06) Slide 21

Limitations Small sample size confounding factors Bias Slide 22 Discussion

Conclusions unable to demonstrate a conclusive of appropriate in pre-hospital airway management on survival trauma patients in a propensity-adjusted model. These finding further strength to the need for prospective, randomized studies to identify those patients that might achieve a survival benefit from this procedure. Slide 23
