3 E’s
• Engineering
– E.g. smoke detectors, safety features in cars
• Enforcement (and legislation)
– E.g. laws against drunk driving or speeding
• Education: social marketing to promote safe
behaviors
– E.g. seat belt or helmet use.

Pedestrian Safety
Over half of all who die from road traffic crashes
globally are vulnerable road users (VRU):
– Motorcyclists
– Bicyclists
– Pedestrians
Much smaller part of problem in high-income countries
Pedestrian behavior
Multiple road users
Occupational risks and social issues
Preventive measures
Use of space

Priority to pedestrians
Traffic calming
Targeting risk factors: speed
Vehicle speed: a risk to all, especially vulnerable road users

Permanent Disability
• Much injury-related disability is
from extremity injury.
– Example: Most (78%) of injuryrelated disabilities in Ghana are
due to extremity injuries.
• Amenable to improvements in:
– Orthopedic care
– Rehabilitation

CHALLENGES AND GAPS
A. Human Resources:

Latin America 7
Africa
0.5
B. Physical Resources
(supplies, equipment)
Shortages in many critical items,
even those that are low cost.
CHALLENGES AND GAPS
C. Organization and Administration
• Main hospital in Kumasi, Ghana:
– 2022 trauma admissions
• Prolonged time to emergency
surgery: average 12 hours
• Low utilization of:
– fluid and blood resuscitation
– airway equipment
– chest tubes

Improving Existing Ambulance Systems
Monterrey, Mexico
Intervention:
•1. Increase number of ambulance stations
•(2 to 4).
•2. Improved in-service training.
Effect: Mortality of transported
trauma patients decreased:
8.2% to 4.7%.
Cost: 16% of EMS budget.
Source: J Trauma, 48: 119, 2000.
Where to Proceed?
Settings with no formal EMS
One option: Build on existing, less formal, systems.
Example: Ghana, commercial drivers.
•400 received first aid training.
•1 year follow-up: 61% had used the training

Improving Prehospital Care
in Absence of Formal EMS
Northern Iraq and Cambodia, mine infested areas.
Intervention:
Two tier system instituted:
- 5000 lay first responders with 1st aid training.
- Paramedics with 450 hour formal training.
Effect: Mortality decreased: 40% to 9%.

11 essential services –
Rights of the Injured:
Brief examples
• Assure that obstructed
airways are opened
• Assure that bleeding
(external or internal) is
stopped
• Assure that potentially
disabling orthopedic
injuries are corrected
Inputs needed: Low income settings
• All rural clinics
caring for injured
persons:
• Capabilities (training
and equipment) for:
rapid basic first aid
At least one third of rural injured
cared for at such facilities.
Inputs needed: Low income settings
District Hospitals
• Capabilities for chest
tubes and airway
maintenance
• Minimum blood
transfusion capabilities
Inputs needed: Low income settings
Tertiary care hospitals
• Endotracheal intubation
in casualty ward
(emergency basis)
• Basic quality
improvement programs
Middle income setting
• Similar recommendations: but including items that
increase probability of successful outcome, but also
increase cost.

For all this work there is a
need to engage the public
The landmarks of political, economic, and social history are
the moments when some condition passed from the category
of the given into the category of the intolerable…the history
of public health might well be written as a record of
successive re-definings of the unacceptable.
