Study Notes
Road Traffic Crashes
- 34 injuries per 100,000 people annually worldwide
- 1.35 million deaths annually worldwide
- 80% of hospital deaths in Saudi Arabia are due to road traffic injuries
- 20% of hospital bed occupancy in Saudi Arabia is related to road traffic injuries
- Young, economically productive males are the most affected by road traffic crashes
Contributing Factors
- Human Factors*
- Speeding
- Reckless driving
- Younger drivers
- Vehicle Factors*
- Vehicle factors play a minimal role in crashes
- Environmental Factors*
- Weekday rush hour
- Weather has minimal influence
Safety Strategies
- Active Safety Strategies (Prevent crashes)*
- Blind Spot Detection
- Road Sign Recognition Systems
- Lane Departure Warning Systems
- Passive Safety Strategies (Minimize injury during crashes)*
- Airbags
- Seatbelts
- Whiplash Protection Systems
- Pedestrian Safety Features
Haddon Matrix
-
Primary prevention: Strategies that prevent accidents from happening in the first place
-
Examples:
- Speed limits
- Driver education
- Road design improvement
- Enforcement of traffic laws
-
Examples:
-
Secondary prevention: Strategies that minimize the severity of an accident once it has occurred
-
Examples:
- Seatbelts
- Airbags
- Crash-resistant vehicle design
- Emergency medical services
-
Examples:
-
Tertiary prevention: Strategies that minimize the long-term impact of an accident
-
Examples:
- Rehabilitation services
- Disability support
- Psychological counseling
-
Examples:
Effectiveness of Strategies
- Evidence supports the effectiveness of active and passive safety strategies in reducing crashes and injuries
Tuberculosis in Saudi Arabia
- Myths and Taboos*
- TB is hereditary: False
- TB always leads to death: False
- TB treatment is expensive: Treatment is free in Saudi Arabia and many other countries
- You can only get TB once: False
- All TB patients are contagious: False, depends on whether the patient has active TB
- Fact*: TB is spread via airborne transmission
Counseling Strategies
- Educate patients and families about TB
- Dispute myths and taboos
- **Provide emotional support for patients: ** TB patients may experience depression, feeling burdened, and isolation
- Discuss medications and side effects: TB medications can have side effects and can lead to feelings of helplessness in families.
-
Address sensitive topics such as:
- HIV
- Substance abuse (including smoking and alcohol)
Social Factors Contributing to TB
- Poverty:
- Immigrants:
- Prisoners
TB Control
- Screening Methods*
- Mantoux (TST)
- IGRA
- MTB culture
- Microscopy
- National Tuberculosis Control Program (NTP)*
-
Aims:
- Decrease incidence rate to 1/100,000
- Treat over 85% of TB patients
- Detect over 70% of estimated TB cases
- Provide BCG vaccination to all children
-
Strategies:
- Directly Observed Treatment, Short Course (DOTS)
- Health education
- Central Unit: in the public health agency
- TB control manual: reference
- Laboratory services: 3 levels: peripheral, intermediate/regional, and central/national
- Treatment services: provided throughout treatment
- Training: for all healthcare professionals working with NTP
- Supervision and evaluation: evaluate implementation and manage obstacles
- Surveillance system: to identify and register cases and notify authorities
Role of Family in TB Management
- Nutrition support: Families can help patients with nutrition to improve endurance
- Informational support: Reminders to take medication and accompanying patients to appointments
- Emotional and psychological support: Helping patients feel motivated during treatment
Preventive Measures
-
For Family and Healthcare Workers*
-
Administrative control: Reduce exposure to patients with infectious TB
-
Environmental control: Reduce the concentration of infectious droplets
-
Respiratory control: Use personal protective equipment (PPE)
Contact Tracing
- The public health nurse investigates all close contacts of a confirmed TB case
- Close contact defined as: close, regular, prolonged contact with a patient while they are infectious, without wearing proper PPE
- Screening and education for close contacts
Vaccination
-
Nature of Vaccines*
-
Live attenuated vaccine: weakened pathogen; chickenpox, yellow fever, MMR, Sputnik
-
Inactivated vaccine: dead pathogen; hepatitis A, rabies
-
Subunit/conjugate vaccine: pieces of pathogen; pneumococcal, HPV
-
Toxoid vaccine: toxin of pathogen; tetanus
-
mRNA vaccine: leading the body to synthesize the foreign protein; COVID-19 Pfizer
-
Viral vector vaccine: antigen similar to target pathogen; COVID-19 AstraZeneca
-
Impact of Vaccines*
-
Herd Immunity:

Increased life expectancy
-
Economic growth promotion
-
Protection against bioterrorism
-
Control of morbidity and mortality
-
Mitigation of disease severity
-
Prevention of infection
-
Vaccines Available in Saudi Arabia*
-

- Tdap: booster shot at age 11
- MMR: measles, mumps, and rubella
- Polio
- Influenza
- Meningitis
- Pneumococcal pneumonia
- Varicella influenza
- HPV
- Herpes zoster

Systemic Thinking in Healthcare
-
Adverse Events*
-
Adverse effect: an undesired harmful effect
-
Side effect: secondary to a main therapeutic effect
-
One in ten patients is harmed while receiving hospital care globally
-
50% of adverse events are preventable
-
Serious adverse events include death, disability, permanent damage, congenital anomalies
-
Medical Errors*
-
Errors occur by doing the wrong thing (commission) or failing to do the right thing (omission)
-
Iatrogenesis: medical errors defined as mistakes, inadvertent occurrences, or unintended events in healthcare delivery that may result in patient injury.
-
Preventable causes: fatigue, user error, inexperience, human errors
-
Most common preventable errors: misdiagnosis, delayed diagnosis, faulty medical device, infection
-
Systemic Approach*
-
Shift from blame culture to a just culture to minimize future adverse events.
-
Factors leading to errors:
- Lack of standard procedures
- Poor communication
- Lack of verification
- Lack of patient involvement
-
Minimizing Adverse Events*
-
Mature health system: takes into account the increasing complexity in healthcare settings that make humans more prone to mistakes.
-
Physician disclosure of adverse events: to patients and institutions
-
Financial burden for patients: institutions should ensure patients are not burdened financially
-
Root cause analysis: Conduct a root cause analysis of the adverse event and develop an action plan
