Between 2000 and 2004, four large outbreaks of hepatitis B and hepatitis C viral infections among patients in ambulatory care facilities were attributed to either the reinsertion of used needles into multi-dose vials or solution containers; or the use of a single needle/syringe to administer intravenous medications to multiple patients.

Study Notes
Healthcare Personnel
- Definition includes all paid or unpaid individuals providing patient care or support services in healthcare settings.
Nosocomial Infections
- Nosocomial infections are defined as infections acquired in hospitals.
Chain of Infection
- The transmission of infectious agents requires a source, a susceptible host, and a mode of transmission.
Sources of Infectious Agents
- Pathogens linked to healthcare-associated infections (HCIs) primarily originate from human sources, contaminated objects, and environmental sources.
- Incorrect assumption: Human sources exclude household members and visitors.
Susceptible Hosts
- Factors influencing infections in hosts include organism characteristics (numbers, pathogenicity, virulence) and host defense mechanisms.
- Susceptible hosts may experience asymptomatic colonization or progress to symptomatic disease.
Pathogen Transmission
- Pathogens can be transmitted through direct or indirect contact, respiratory droplets, and airborne particles.
Airborne Transmission
- Droplet nuclei are small airborne particles that can remain suspended and may not be limited to 3 feet from the source.
Standard Precautions
- Standard Precautions are applicable universally across healthcare settings to prevent healthcare-associated infections, irrespective of the patient’s infection status.
Respiratory Hygiene/Cough Etiquette
- Developed during the 2003 SARS outbreak, emphasizing the importance of source control measures.
Source Control Measures
- Includes turning away, using tissues, and practicing hand hygiene after exposure to respiratory secretions.
Health Care Personnel Protocols
- Healthcare personnel with respiratory infections must adhere to contact and droplet precautions, including PPE usage.
Safe Injection Practices
- Emphasize single-use syringes and do not administer medications from single-dose vials to multiple patients.
Transmission-Based Precautions
- Types include contact, droplet, and airborne precautions, implemented based on pathogen identification.
Airborne Precautions Controls
- Incorporate administrative, environmental, and respiratory-protection controls to minimize airborne pathogen transmission.
Airborne Isolation Rooms (AIIRs)
- AIIRs maintain negative pressure and are equipped with efficient air filtration systems to manage airborne infections.
Respiratory Protection Controls
- Incorrect assumption about controls reducing exposure areas to minimize the exposure of personnel; instead, they focus on individual protections.
Role of Infection Prevention Coordinator (IPC)
- IPC's responsibilities extend to developing protocols and monitoring adherence but do not include overall compliance responsibility.
Infection Prevention Strategies
- Should be suited to the healthcare setting, addressing all clinical processes, and evaluated through structure, process, and outcome metrics.
Infection Prevention Education
- Continuous education on protocols is imperative; training cannot be a one-time requirement due to ongoing risks associated with infections.
