Event-Related Sterility and Sterile Storage: AAMI ST79/ST58 Requirements
Sterility under ST79/ST58 is event-related, not time-related: it depends on packaging integrity, handling, and storage conditions, not a printed date. This guide covers what governs it and how to handle a compromised package.
Low-Temperature Sterilization Method Selection: EtO vs. VHP vs. Ozone
Choosing among ethylene oxide, vaporized/plasma hydrogen peroxide, and ozone for heat- or moisture-sensitive instruments — a decision matrix by material compatibility, lumen restriction, and cycle time, not a single-method explainer.

VAE: NHSN Surveillance Definition, VAC/IVAC/PVAP Criteria, and Reporting
A ventilator-associated event is an NHSN surveillance category built from a baseline period of stability, a sustained PEEP/FiO2 rise, and the VAC, IVAC and PVAP tiers — distinct from a clinical diagnosis of ventilator-associated pneumonia.
Antibiogram: How to Build and Read a Cumulative Antibiogram
A cumulative antibiogram summarises how local bacterial isolates responded to antimicrobial testing, so clinicians can choose empirical therapy before culture results return. CLSI M39 governs how it is built. This guide covers the construction decisions that change the numbers — isolate de-duplication, surveillance-isolate exclusion, stratification, agent selection and intermediate-result handling — and the specific ways antibiograms are misread.
Transmission-Based Precautions: Contact, Droplet, and Airborne
Contact, droplet, and airborne precautions each specify a different PPE and room-placement standard under the CDC/HICPAC isolation guideline.

Infection Control Risk Assessment (ICRA) for Construction
An infection control risk assessment (ICRA) is a required pre-construction process at healthcare facilities: a risk matrix that crosses the type of construction activity against the patient population it will affect to determine a required class of infection-control precautions before work can begin.
Airborne Infection Isolation Room (AIIR): Specifications and Monitoring
An airborne infection isolation room (AIIR) is an engineering control, not just a sign on a door — a negative-pressure single-patient room built and monitored to contain and remove airborne pathogens like tuberculosis, measles, and varicella before they reach the corridor or other patients.
Endoscope Reprocessing: The Process and Where It Fails
Flexible endoscopes are semicritical devices under the Spaulding classification, which means high-level disinfection is the regulatory floor — but the real-world reprocessing sequence is long, manual-step-dependent, and has well-documented, recurring failure points that make this one of the highest-liability procedures in a healthcare facility.
High-Level Disinfection and the Spaulding Classification
The Spaulding classification is the decision framework behind reprocessing: it sorts a device into critical, semicritical, or noncritical based on how it contacts the patient, and that category — not habit or convenience — determines whether it must be sterilized, high-level disinfected, or only low-level disinfected.
Antimicrobial Stewardship Program: CDC Core Elements and Requirements
How hospital antimicrobial stewardship programs are structured around CDC’s seven Core Elements, why Joint Commission MM.09.01.01 and CMS Conditions of Participation make them mandatory, and how the role differs from infection prevention.
