    The Types and Study of Injuries

    Due to Accident?

    What to do from a PH perspective?

  • Injuries Defined by WHOResulting from traffic collisions, drowning, poisoning, falls or burns - and violence - from assault , self-inflicted violence or acts of warkill more than five million people worldwide annually and cause harm to millions moreAccount for 9% of global mortality, and are a threat to health in every country of the world.

    For every death, it is estimated that there are dozens of hospitalizations, hundreds of emergency department visits and thousands of doctors appointmentsA large proportion of people surviving their injuries incurs temporary or permanent disabilities.

  • Injury from A PH PerspectiveAn emerging topic in global health todayinjury epidemiologyInjuries represent a significant burden today in both developed and developing economies

    Capture our interest very frequently through catastrophesan airplane crash or the car crash in which Princess Diana diedTo reduce their burden into the futureMany questions remain about the appropriate way to do this

  • A couple drowns after their boat capsizes with no life vests on board. These incidents are often dismissed as "accidents." Correcting these misperceptions is part of the mission of the Harborview Injury Prevention and Research Center (HIPRC).

    In 1985, the National Academy of Sciences issued a report that described injuries as the "most important public health problem facing our nation today". That same year the HIPRC was formed as one of the first centers in the nation specifically devoted to research on and prevention of injuries.

  • To Study Injury

    Injury EpidemiologyAn Introduction

  • From The Epidemiological PstvWhat are injuries?

    Why should we have an interest in injuries and research into the epidemiology of injuries?

  • Causes of InjurySource: http://www.pitt.edu/~super1/lecture/lec0231/index.htm

  • All injuries can be characterized as suchInjuries arising from automobile crashes can be characterized as injuries which arise from the transfer of energy between the victim and a stationary object (the ground) or a moving object (another vehicle), which lead to trauma and possibly death. Abnormal Energy Transfer

  • Ways of Energy Transfer n InjuryPenetrating

  • Energy Transfer and InjuryPenetratinglocalized in one area

  • Where Does Epidemiology Tie in?Epidemiologists interested in injuries?Injuries, a leading cause of mortality and morbidity in both the developed and developing worldchallenge to both understand the basic underpinnings of their occurrence (the frequency risk factors) and to develop intervention programs to reduce their impactthe work of William HaddonElegantly outlined how epi applications have relevance to injuries (discussed further later)

  • Where Do Injuries Stand among"The Global Burden of Disease", Harvard University Press, 1996.

  • Injuries Standings in USA

  • YLL, or YPLL as in The Textbook

  • What factors may account for this observation?

  • What events could explain this observation? Several factorsThe item of comparison, injury mortality, is quite broad. Injuries encompass a wide variety of categories, from accidents to homicides to falls and poisonings.Injuries from one category, e.g. crashes or violence, may be more common in some areasPublic transport systems may be better developed in some areasEconomic development in its initial stages may lead to higher rates of occupational injuries. Can you think of other reasons?

  • What to Do about Injuries?Injury ControlIn its simplest form, injury prevention and control represents a reduction in the incidence and/or prevalence of an injury

  • John Last in the Dictionary of Epidemiology (Oxford University Press)Prevention of injuries is characterized by a reduction in the incidence of injury events.Injury control denotes the programs that seek to reduce the frequency and severity of injuries.

  • Without a doubt, the father of injury epidemiology and injury control is William Haddon. The former director of the National Highway Traffic Safety Administration and the Insurance Institute for Highway Safety played a leading role in bringing epidemiologic principles to injury research and intervention programs.
