Accident and Injury Prevention

Accidents & Injuries - Injury Numbers Game

• Global: Injuries cause ~9% of all deaths; ~5 million deaths annually.
• India: Leading cause of death & DALYs in 15-49 age group.
  • Road Traffic Accidents (RTAs): ~1.5 lakh deaths/year (NCRB).
  • Falls: Significant in elderly (>65 yrs) & children (<5 yrs).
  • Burns: Higher incidence in females; often domestic.
  • Drowning: Leading unintentional injury death in children 1-4 yrs.
  • Suicides: Significant cause of death in 15-29 yrs.

⭐ India accounts for ~11% of global road accident deaths, despite having only 1% of the world's vehicles.

RTAs - Highway Hazards

• Leading cause of death & disability (age 15-49 yrs).
• Risk Factors:
  • Driver: Alcohol (BAC >30mg/dL), speeding, fatigue, distraction, no helmet/seatbelt.
  • Vehicle: Poor maintenance (brakes, tyres), overloading.
  • Road: Potholes, poor design, ↓lighting, blind spots.
  • Environment: Weather (fog, rain), night driving.
• Prevention (Haddon''s Matrix):
  • Pre-event: Education, vehicle safety, road engineering, speed limits.
  • Event: Helmets, seatbelts, airbags.
  • Post-event: Golden hour care, trauma services, rapid EMS.
• 📌 4 ''E''s: Engineering, Enforcement, Education, Emergency services.

• ⭐ > India has ~11% of global road deaths but only 1% of world''s vehicles.

Other Injuries - Beyond the Road

• Falls: Leading cause of non-fatal injuries, esp. elderly (>65 yrs) & children.
  • Prevention: Home safety modifications (e.g., grab bars, non-slip mats, adequate lighting), balance training, medication review.
• Burns: Common types: scalds (children), flame (adults), chemical, electrical.
  • Prevention: Smoke alarms, fire safety education, safe cooking practices, child supervision.
  • Assessment: Rule of Nines for estimating Total Body Surface Area (%TBSA) burned.
• Drowning: High risk for children <5 yrs & young adults.
  • Prevention: Four key strategies (📌BARS): Barriers (pool fencing), Adult supervision, Reduce hazards, Swimming skills & water safety training, CPR knowledge.
• Poisoning: Peak incidence in children <5 years.
  • Prevention: Safe storage of medicines & chemicals, child-resistant containers, proper labeling.

  ⭐ Kerosene is a common agent in accidental childhood poisoning in India, often leading to severe chemical pneumonitis.

• Occupational Injuries: Common in agriculture, construction, manufacturing.
  • Prevention: Use of Personal Protective Equipment (PPE), safety training, ergonomic design, hazard identification.

Injury Prevention - Haddon's Helper

Haddon's Matrix is a key framework for analyzing injuries and identifying prevention strategies. It considers:

• Three Phases (Temporal):
  • Pre-event: Prevent the incident (e.g., driver training, road design).
  • Event: Reduce injury severity during the incident (e.g., airbags, helmets).
  • Post-event: Minimize consequences after injury (e.g., rapid EMS response, rehabilitation).
• Three Factors (Epidemiological):
  • Human: Host characteristics, behavior (e.g., age, alcohol use).
  • Agent/Vehicle: The object or vehicle delivering energy (e.g., car, firearm).
  • Environment: Physical and socio-cultural setting (e.g., weather, laws).

This creates a 3x3 grid, yielding nine cells for targeted interventions.

⭐ Originally developed for traffic safety by William Haddon, Haddon's Matrix is versatile for all injury prevention (e.g., falls, burns, drowning).

High‑Yield Points - ⚡ Biggest Takeaways

• Road Traffic Accidents (RTAs) are a leading cause of mortality; helmets and seatbelts are crucial.
• Haddon's Matrix is vital for accident analysis (pre-event, event, post-event & host, agent, environment).
• Primary prevention (e.g., speed limits, safe roads) is most effective for injury control.
• The "Golden Hour" significantly impacts trauma survival rates.
• Common injuries include childhood poisoning (e.g., kerosene) and falls in elderly.
• Injury surveillance is essential for effective prevention strategies.
