Khannistha Mahem ID The Effect of Pre-Hospital Airway Management on Mortality among Accidental Injury Patients, Khon Kaen Hospital in Thailand

Outline Background & Rational Objective Methodology Result Discussion Conclusion

Background & Rationale Road Traffic Accidents Death Rate Per 100,000Data; Source: WHO 2011

Background & Rationale (World Wide) Causes of injuries,2011 WHO 2011

Background & Rationale (Thailand) Top 5 Caused of death,2010

Background & Rationale (Khon Kaen) New Year Normally number/day New Year Normally number/day

Background & Rationale (Pre-hospital care) crisis 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 (National Injury Surveillance) severe injury patients almost referred to hospital by EMS 36.11% relationship 61.19% and non registered organization 0.4%

Background & Rationale (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%

Los Angeles study Pre-hospital endotracheal intubation in isolated, moderate to severe TBI patients is associated with a nearly 5-fold increase in mortality. Further prospective studies are required to establish guide- lines for optimal pre-hospital management of this critically injured patient population Prior Studies (The pre-hospital airway management )

Cudnik,et al. [2010] There were 877 consecutive trauma patients who had pre-hospital ETI during this period and were included in the analysis. Of these, 496 (57%) had RSI-ETI. In univariate analyses, those with RSI-ETI had less severe injuries, better pre-hospital physiology lower unadjusted mortality than those intubated without RSI. However, 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)

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

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

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

Result Factors associated with Mortality

Discussion pre-hospital inappropriate airway management was associated with significantly increased mortality (ORc 5.78, 95%CI: 2.14 to15.59; p=0.004) Then….. (ORadj 3.42, 95% CI: 0.42 to27.91, p< 0.001)

Discussion Theoretical principle Los Angeles study Cudnik,et al. Strength & Limitations Small sample size confounding factors bias

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.
