  3. 3. DEFINITIONS• ACCIDENT• Unexpected, unplanned occurrence of an event which may involve injury.• In 1956 WHO advisory group defined accidents as – Unpremeditated event resulting in recognizable damage.• Occurrence in a sequence of events which usually produce unintended injury, death or property damage.
  4. 4. DEFINITIONS INJURYA bodily lesion due to acute exposure to energy beyond the physiological tolerance.
  5. 5. • Accidents are the part of prize we are paying for technological advances.• Like other diseases accidents are also having – • Natural history of disease and • Agent, Host and Environmental factors
  6. 6. Epidemiology of Injuries Injury as a diseasePathologic Host Agent Vector Inter-condition /vehicle actionMalaria Human Plasmodium Mosquito Bite vivaxSkull Human Mechanical Motorcycle Crashfracture Energy

  8. 8. How to Measure the Problem of AccidentMortality:• Proportionate Mortality Rate – Number of deaths due to accidents out of 100 total deaths• Number of deaths per million population – Killed in Road Traffic Accident (RTA) is defined as any person who was killed outright or who died within 30 days as a result of accident.• Death Rate per 1000 registered vehicles per year• Number of accidents or fatalities as a ratio of number of vehicles per km OR passenger per km.
  9. 9. • Morbidity: – Measured in terms of • Slight injury and • Serious injury• Disability: – Disability is one of the important outcome of accidents • Temporary or Permanent disability • Partial or Total disability
  10. 10. Problem statementWorld:• Accidents are endemic all over the world• Accidents are major cause of deaths in the age-group of 10-24 yrsIn developed countries -• 57% of male death and• 43% of female death in 10-24 yrs are due to accidents.• RTA and drowning are the main causes of death in that age-group.
  11. 11. In SEAR:• Out of total 5.1 million accident deaths in the world 1/4th in SEAR.• So thousands of children saved from Nutritional and infectious disease are killed by accidents.India:• Increasing trends in India due to – Mechanization in agriculture and industries – Increase in vehicular traffic• Plus factors like – Overcrowding – Lack of awareness and – Poor implementation of safety precautions
  12. 12. Types of accidents• Road Traffic Accidents (RTA)• Domestic accidents – Drowning – Burns – Falls• Industrial Accidents• Railway accidents• Violence
  13. 13. Causes of accidents• Accidents are complex phenomena with multiple causation• Etiological factors are classified to – Human – Environmental – Psychosocial factors
  14. 14. Human factor Environmental factor • Age • Relating to road • Sex • Relating to • Education vehicle • Psychological • Bad weather factor • Mix traffic • Lack of body Increase protection vulnerability and riskPrecipitating factor situation ACCIDENT
  15. 15. Human factor• Age:15-44 yrs(50% mortality)• Sex: More in males• Education: Low educational status• Medical condition • Sudden illness • Heart attack • Impaired vision• Fatigue• Lack of protection – Helmet
  16. 16. Psychosocial• Lack of experience• Risk taking behavior• Impulsiveness• Defective judgment• Delay in decision• Aggressiveness• Poor perception• Family dysfunction
  17. 17. Environmental• Related to Roads: – Defective and narrow roads – Defective lay out of cross-roads, – speed breakers – Poor lighting
  18. 18. Environmental• Related to Vehicles: – High speed – Poorly maintained vehicles – Large number of 2-3 wheelers – Overloaded bus – Low driving standards• Bad Weather
  19. 19. Environmental• Inadequate laws• Mixed Traffic – Pedestrian – Animals and vehicles
  20. 20. Precipitating factors• Increased emotional tension• Use of Alcohol during driving
  21. 21. Precipitating factors• Stolen vehicle• Group traveling
  22. 22. Road Traffic Accident• “Road Safety is No Accident” – was the slogan given by WHO for World Health Day – 2004.• 85% of all road accident deaths occur in developing countries and nearly half in the Asia-Pacific region.• India has one of the largest highway and road networks second only to road network of U.S.
  23. 23. Road safety advertising
  24. 24. How accidents in developing countries differ from developed countries: • Two wheelers are more involved • Pedestrians are more involved
  25. 25. How accidents in developing countries differ from developed countries:• Large number of old and poorly maintained vehicles• Overloaded buses
  26. 26. How accidents in developing countries differ from developed countries:• Disregard towards traffic rules
  27. 27. How accidents in developing countries differ from developed countries:• Poor road standards
  28. 28. How accidents in developing countries differ from developed countries:• Unusual behavior of human and animals
  29. 29. • Unusual behavior of car
  30. 30. Domestic accidents• Accidents which takes place in home or in its immediate surrounding, which are not connected with traffic vehicles or sports.• Common domestic accidents are- – Drowning – Burns by flame, – hot liquid, – electricity, – crackers, chemicals – Falls – Injury by sharp objects – Animal bites.
  31. 31. Drowning• After immersion in water victim loses consciousness with in 2 min. and• Irreversible brain damage occurs at 4 – 6 minutes.
  32. 32. Prevention and control of drowningAvailability of life jackets and flotation devicesaround pools & boatsSupervision of children by adultsFencing of lakes and pondsCreation of safety standards for public andprivate swimming poolsEnsuring availability of weather reports to fishermen and to those working on rivers and seas
  33. 33. Burns• Factors associated with burns – Explosion of pressure stove. – Cooking on open fire – Use of open fire during winter – Use of inflammable material – Method of suicide
  34. 34. Prevention and control of burns Stable stoves/lamps Replacement of pressure stoves with wick and gas stoves Installation of fire and smoke alarm Promotion of cold water for first aid and burns
  35. 35. Poisoning• Most common agents are – – Kerosene – Pesticides – Household chemicals – Drugs• Kerosene poisoning common among children.
  36. 36. Fall• Large number of hospital visits among children and young adults for non-fatal injuries.• Fall from – Roof, balcony, stair-case, window are common.• Among construction workers are common
  37. 37. Fall
  38. 38. • Prevention and control of falls• 1.Safer playground (Use of mud & sand surfaces instead of paved ones)• 2.Safer furniture & house designs• 3.Use of grills on windows• 4.Safer design of stairs, balconies and rooftops with railings and bars• 5.Safer working techniques for construction workers
  39. 39. Industrial accidents• Approximately 580 million workers in SEAR.• 60-80% are in small scale units
  40. 40.  Prevention and control of industrial accidents Ensuring the cost effective protection measures Enforcing safety regulations and standards Creating awareness among workers
  41. 41. Railway accidents• In India railway accidents are in increasing trend due to – Increasing number of trains – More number of passengers
  42. 42. Violence• Risk factors for violent behavior: – Exposure to violence and societal acceptability of violence as a mode to solve the problem – Availability of lethal weapon at home – Consumption of alcohol
  43. 43. • Suicide are increasing in SEAR region – 36/1,00,000 in India – 22/1,00,000 in Thailand – 11/1,00,000 in Bangladesh – 8/1,00,000 in Srilanka• Common methods of suicide: – Hanging – Drowning• 70% of cases of suicide in 15-35 yrs age• M:F ratio is 1:13 to 1:3
  44. 44. Prevention of Accidents• Multi-sectorial approach approach for prevention.Data collection:• Reporting system for accidents• Special surveys for accidents – Risk factors – Circumstances – Chain of event• No effective system of prevention without data collection.
  45. 45. Safety education:• “Accident is a Disease – Education is its Vaccine” – Should start from school days – Drivers trained for vehicle maintenance and safe driving. – Education about traffic rules – Training in First Aid.Promotion of Safety measures: – Helmets – Seatbelts – Leather clothing and boots
