Medical and Dental Office CSSD Errors

Updated: Mar 10, 2022

Light bulb - Thought of the Week

During the last 15 years, I have been involved in inspecting and training individuals who reprocess instrumentation in medical and dental practices and specialty care centers. ECRI recently listed medical and dental sterilization practices as the #3 hazard for 2020 ( The following list is some of the errors that I have found during the last decade and a half.

Decontamination Area

  • cross-contamination during the process flow

  • incorrect dilution of chemicals

  • lack of proper use of chemicals

  • high-level disinfection chemical misuse

  • improper airflow

  • improper PPE use

  • improper equipment for cleaning

  • lack of critical water use

  • improper cleaning of ophthalmic instrumentation

  • improper transportation of soiled items

  • lack of keeping soiled instruments moist prior to cleaning

Preparation and Packaging Area

  • improper packaging

  • improper labeling

  • improper inspection of instrumentation

  • expired packaging and supplies

Sterilization Area

  • lack of verification of sterilization cycles

  • improper loading of sterilizers

  • improper cleaning of sterilizers

  • improper shelf life of sterilized items

  • improper storage of sterilized items

Departmental Administrative Area

  • outdated policies

  • lack of instructions for use (IFU)

  • lack of a quality management system

  • lack of a continuing education plan

  • lack of training documentation

  • lack of an annual risk assessment

  • improper attire policies

  • lack of an orientation plan

I am sure I have left out a few findings. To help create a risk assessment for your area, visit OSAP (, AAMI (, or the CDC ( It is the management teams' responsibility and the owners of small businesses to keep their patients safe.
