The Fundamentals of Sterile Processing

Sterile processing is the unsung hero of the healthcare world, ensuring that surgical instruments and medical devices are free from pesky microorganisms and viruses before they come into contact with patients. This process is vital to patient safety and the success of medical procedures. After all, no one wants a surgical site infection to rain on their parade, right?

Behind the scenes, sterile processing technicians:

  • Maintain operational excellence by cleaning, sterilizing, and preparing medical equipment for use in surgeries and other medical procedures
  • Must pay close attention to detail to ensure that the sterilization process is completed flawlessly
  • Are the ones who take charge and decide how to best use sterilization equipment and resources when the stakes are high

Ethylene oxide sterilization, a highly effective method at eliminating microorganisms and viruses, is frequently employed to achieve sterilization. Their meticulous work enables sterile processing technicians to significantly contribute to the reduction of surgical site infections. In 2020, there was a notable decrease in the surgical site infection standardized infection ratio. This decrease was approximately 5% compared to the previous year.

Sterile Processing Department (SPD)

The Sterile Processing Department (SPD) takes charge of cleaning, sterilizing, and prepping medical devices for a range of medical procedures. The SPD is divided into several areas, including:

  1. Decontamination
  2. Assembly and sterile processing
  3. Sterile storage
  4. Distribution

Each area plays a crucial role in ensuring that medical tools and medical supplies are ready for use in surgical procedures within the operating room.

The decontamination area is where the magic begins. Here, medical devices go through a thorough decontamination process, including manual cleaning, to remove any contaminants before they’re sent for sterilization. The use of proper containment devices for the instruments ensures that they remain clean until they’re ready to be used again. Biological indicators are employed to guarantee the efficacy of the sterilization process. They provide key measurements for this purpose.

Once sterilization is complete, the sterilized instruments are carefully packaged in the packaging area, prepared for storage and distribution. This process helps maintain the sterility of the instruments and supplies until they’re needed for use in medical procedures.

In healthcare facilities, the SPD performs a significant role by ensuring every instrument and device used in medical procedures is adequately cleaned, sterilized, and primed for use. Patient safety is always at the forefront of SPD operations, and their diligent work helps minimize the risk of healthcare-associated infections.

Quality Assurance in Sterile Processing

In sterile processing, achieving sterility for every reprocessing cycle is pivotal, underlining the immense importance of quality assurance. To guarantee the sterility of instruments and supplies, a variety of monitoring methods are used, including biological and chemical indicators, as well as mechanical devices such as gauges, thermometers, timers, and recorders.

Test packs and other biological indicators are employed to validate the effective exposure of instruments to conditions necessary for sterility during the sterilization process. Chemical indicators are also used to monitor the sterilization process and provide visual confirmation that the sterilization parameters have been met.

Maintaining documentation at the instrument level remains integral to ensuring patient safety during surgical procedures. Policies and procedures must be in place to guarantee the sterility of instruments and supplies, which in turn helps prevent healthcare-associated infections.

Depending on the type of sterilization being used, such as steam under pressure or ethylene oxide, testing a biological indicator involves incubation of the sterilized units and the control at specific temperatures for a predetermined period. This crucial step verifies the effectiveness of the sterilization cycle, ensuring that medical tools are safe for use in medical procedures.

Preparing for a Career as a Sterile Processing Technician

For those contemplating a career as a sterile processing technician, a minimum requirement is a high school diploma or its equivalent. Enrolling in a sterile processing technician course can teach you about sterilization parameters and other essential skills required for this important role in healthcare.

A myriad of career opportunities, ranging from sterile processing supervisor to nursing, can be explored by sterile processing technicians. The job market for sterile processing techs is promising, with the U.S. Bureau of Labor Statistics predicting a 6% job growth until 2031, driven by the increasing demand for sterile supplies in healthcare settings.

To become a certified sterile processing technician, you’ll need to:

  1. Research certification organizations, such as the International Association of Healthcare Central Service Materiel Management (IAHCSMM) and the Certification Board for Sterile Processing and Distribution (CBSPD).
  2. Gain hands-on experience through an internship to hone your skills and prepare for the certification exam.
  3. Remember, certifications are typically valid for about five years, so stay up-to-date on your credentials to maintain your competitive edge in the field.


Sterile processing is an essential aspect of the healthcare system, ensuring that medical instruments and devices are clean, sterile, and ready for use in medical procedures. Sterile processing technicians play a crucial role in maintaining patient safety and preventing healthcare-associated infections. By pursuing a career in this field, you can make a meaningful impact on the healthcare industry and the lives of countless patients.
