There are several effective infection prevention and control models that have been widely recognized and implemented in healthcare settings. Here are some of the best models:
Standard Precautions: This model is the foundation of infection prevention and control. It includes basic infection control practices such as hand hygiene, personal protective equipment (PPE) use, safe injection practices, respiratory hygiene, and environmental cleaning.
Transmission-Based Precautions: These precautions are used in addition to standard precautions for patients with known or suspected infections that require additional measures to prevent transmission. The three types of transmission-based precautions are contact precautions, droplet precautions, and airborne precautions.
The Hierarchy of Controls: This model emphasizes a systematic approach to infection prevention and control. It includes five levels of controls, ranked from most to least effective: elimination, substitution, engineering controls, administrative controls, and personal protective equipment.
Bundles: Infection prevention bundles are sets of evidence-based practices designed to prevent healthcare-associated infections. These bundles usually include a combination of interventions that, when implemented together, have been shown to be more effective than individual measures alone. Examples include ventilator-associated pneumonia bundles, central line-associated bloodstream infection bundles, and surgical site infection prevention bundles.
Enhanced Barrier Precautions: This model is specifically designed for patients with highly transmissible or multidrug-resistant organisms. It includes additional measures such as enhanced hand hygiene, dedicated equipment, cohorting, and enhanced environmental cleaning.
Antibiotic Stewardship Programs: These programs focus on optimizing the use of antibiotics to prevent the development and spread of antibiotic-resistant infections. They include strategies such as appropriate antibiotic prescribing, de-escalation of therapy, and regular review of antibiotic use.
Outbreak Management: This model involves a systematic approach to identify, investigate, and control outbreaks of infections within healthcare facilities. It includes surveillance, early detection, rapid response, and communication strategies.
