Feb 2025 Infection Control Updates & Dental Unit Waterlines On-Demand-Infection Control and Waterlines Video

Video Transcription

Video Summary

Dr. Marie Flewitt delivered a Georgia-focused infection control update emphasizing regulatory compliance and dental unit waterline safety. She explained that Georgia requires adherence to CDC infection control guidance (2003 Guidelines and the 2016 Summary), along with OSHA rules, Georgia Board of Dentistry regulations, and—critically—manufacturers’ Instructions for Use (IFUs), noting failure to follow IFUs can create liability.<br /><br />She reviewed disease transmission routes (direct/indirect contact, droplets, aerosols), standard precautions, and when transmission-based precautions are needed. Key prevention strategies include work practice controls, administrative controls (training records, written policies, designated infection control coordinator), and engineering controls. She highlighted occupational exposure response: immediate first aid, prompt reporting, and urgent evaluation for possible post-exposure prophylaxis (ideally immediately; within 72 hours maximum). Recommended healthcare worker vaccinations were summarized (HBV, flu, MMR, varicella, Tdap, COVID).<br /><br />Flewitt covered hand hygiene, PPE selection (ASTM masks vs N95s and required respiratory protection programs), ventilation/airflow considerations, and instrument reprocessing—from safe transport and cleaning to packaging, autoclave loading, and sterilization monitoring (mechanical, chemical, and weekly biological spore testing).<br /><br />The primary focus was dental unit waterlines: biofilm risks, CDC expectations (flushing, sterile water for surgery), and a structured program of written protocols, staff training, product selection per dental unit IFUs, and routine testing with documentation. She detailed Georgia’s new Board rule 150-8-05 (effective date pending): procedural water must meet EPA drinking water standards (≤500 CFU/mL), testing at least quarterly (more often if inconsistent), testing after plumbing changes, remedial action after failures, and maintaining records for five years. A Q&A addressed urgent care timing after exposures, continued need for water testing even with distilled/filtered systems, shocking and retesting after failures, and pooled sampling pros/cons.
