Study Notes

Patient Safety in Healthcare

Patient safety in healthcare focuses on preventing harm to patients from healthcare-associated infections (HAIs).
HAIs, also known as nosocomial infections, are infections acquired by patients during healthcare treatment.
HAIs can develop within 48 hours after admission or up to 10 days after discharge.
Importance of patient safety from infectious diseases:
- Prevalence: 1 in 10 admitted patients experience HAIs.
- Impact on patient outcomes: HAIs can lead to complications, longer hospital stays, increased healthcare costs, and even death.

Types of Healthcare-Associated Infections (HAIs)

Surgical site infections (SSI): Infections that occur at the site of a surgical procedure.
- Common organisms associated with SSI:
  - Staphylococcus aureus (MRSA): Leading cause of SSI.
  - Coagulase-negative staphylococci (CONS): Includes Staphylococcus epidermidis, associated with clean wounds.
  - Enterococcus species: Particularly in patients with underlying conditions or complex surgeries.
  - Gram-negative bacilli: Can also cause SSI.
Catheter-associated urinary tract infection (CAUTI): Infections associated with indwelling urinary catheters.
- Common organisms associated with CAUTI:
  - E. coli: Most common cause.
  - Klebsiella pneumoniae: Other common cause.
  - Proteus mirabilis: Frequent cause.
Hospital-acquired pneumonia (HAP) or ventilator-associated pneumonia (VAP): Infections affecting the lungs, usually occurring in hospitalized patients or those on mechanical ventilation.
- Common organisms associated with HAP/VAP:
  - Staphylococcus aureus: MRSA can be a cause.
  - Pseudomonas aeruginosa: Common cause.
  - Klebsiella pneumoniae: Frequent cause.
Bloodstream infections (BSI): Infections affecting the bloodstream, often associated with central venous catheters.
- Common organisms associated with BSI:
  - Staphylococcus aureus: MRSA can be a significant cause.
  - Coagulase-negative staphylococci: Can also contribute to BSI.
  - Enterococcus: A common cause, particularly in patients with underlying conditions.
  - Gram-negative bacteria: Can also cause BSI.
  - Fungal infections: Candida species can cause bloodstream infections.
Clostridium difficile infections (CDI): Infections caused by C. difficile, often after antibiotic treatment, that can cause severe diarrhea and colitis.
- Risk Factors for CDI: Antibiotic use.
- Symptoms of CDI: Diarrhea, abdominal pain, fever.
- Severe Cases: Can lead to pseudomembranous colitis.

Causes and Transmission of HAIs

Transmission: HAIs are caused by pathogens that spread through various routes in healthcare settings.
Three components required for infection spread:
- Source: Where the infectious agents survive, like sinks, equipment, and medical devices.
- Environment: Patient care areas, equipment, and devices.
- People: Patients, healthcare workers, and visitors can all spread infection.
Causes of HAIs:
- Person to person transmission: Direct contact through hands.
- Environmental contamination: Indirect contact through fomites (surfaces, equipment, and devices).
- Airborne transmission: Spread through air via respiratory droplets.

Modes of Infection Transmission

Direct contact: Infection transmission through direct contact with an infected individual or contaminated surfaces.
Indirect contact: Infection transmission through contact with fomites (contaminated surfaces, equipment, devices).
Droplet transmission: Infection transmission through respiratory droplets larger than airborne droplets (typically larger than 5µm), traveling short distances (about 2 meters).
Airborne transmission: Transmission through air via small particles, potentially remaining suspended for long periods.
Preventing Transmission:
- Hand hygiene: Essential for preventing the spread of infection.
- Isolation precautions: Using isolation rooms or specific precautions to prevent the spread of infectious agents.
- Decontamination: Cleaning and disinfecting surfaces, equipment, and devices to remove pathogens.
- Vaccination: Effective in preventing several infectious diseases, like influenza.
- Respiratory hygiene: Covering coughs and sneezes to prevent droplet transmission.
- Environmental cleaning: Maintaining a clean and disinfected environment to minimize the spread of pathogens.

Normal Flora of the Skin

Staphylococcus: Common bacteria found on the skin.
Diphtheroids: Another type of bacteria often found on the skin.
Importance: Normal skin flora can contribute to HAIs if they enter the bloodstream or surgical wounds.

Importance of Hand Hygiene in Preventing HAI Transmission

Skin shedding: We shed skin cells containing microbes daily, which can become fomites that spread infection.
Common medical equipment: Can be a source of infection; S. aureus can be transmitted through fomites.
Importance of hand hygiene: Thorough and frequent hand washing with soap and water or using alcohol-based hand sanitizer is vital to prevent the spread of HAIs.
