Best Practice HLD

Best practices are the safest and most effective means of providing care.

Implementing best practice standards and procedures ensures patient and staff safety.


Automated High Level Disinfection (HLD)

Automation mitigates human error risk and provides both staff and facilities confidence that they are providing the highest standard of care for patients.

“The objective was… to replace existing hygiene standards with a practicable, automated solution for the disinfection of ultrasound probes and thus set a new standard in the reprocessing of ultrasound probes… By automating the disinfection process, we obtain reproducibly safe, microbiologically effective reprocessing results, since risks dependent on the 'human factor' are avoided.”

Compliance With Guidelines

Guidelines are essential and designed to help healthcare workers apply best practices to ensure their patients are safe from infection. Manual reprocessing methods often have many steps and rely on the operator to ensure compliance. Automation of some or all of these steps helps minimize human error and decision making for staff and streamlines workflows, improving compliance with guidelines.

A study on human factors impacting endoscope reprocessing found only 1.4% compliance with guidelines when manual cleaning methods were used. Compliance increased to 75.4% among employees using a semi-automated reprocessor.1

Automation makes compliance easier to help you meet best practices.


Validation

Automated devices provide assurance that the critical parameters (e.g. contact time, temperature, concentration) are controlled and all surfaces of the probe head and handle are disinfected.

Manual disinfection does not give you the same quality assurance. Bactericidal efficacy is minimally expected from manual low level disinfection (LLD), however studies continue to show that LLD fails to eliminate bacteria from probes.2-4

Automated HLD with trophon® has been shown to systematically eliminate bacteria every time from probe heads and handles, outperforming manual methods.2,4

Automated methods also incorporate traceability, which is documented evidence the ultrasound probe was properly disinfected before use.


Traceability

Traceability is the documentation collected to link medical devices and their reprocessing records with patient use.5,6

This process is essential for investigations in the event of reprocessing failures, outbreaks or recalls, and can help facilities manage risk. Traceability is required for semi-critical and critical medical devices that undergo HLD or sterilization.

Accrediting agencies look for traceability processes that are compliant with evidence based standards and guidelines. According to American National Standards and the Association of periOperative Registered Nurses, the following data needs to be captured and linked.5,6

  • Device ID & description
  • Date & time of HLD
  • Person performing HLD
  • HLD lot number
  • HLD shelf-life date
  • HLD activation date
  • HLD reuse-life date
  • HLD cycle number
  • Test strip/MEC/MRC testing result 
  • Temperature
  • Exposure time
  • Failed reprocessing cycles
  • Patient ID on whom the device is used
  • Physician performing procedure

Automated collection of some or all of the above data will help streamline workflow, ensure data security and integrity, and minimize risk of human error in record keeping.

Mitigation of Chemical Exposure

In any healthcare setting, it is important that staff and patients are protected from chemical exposure risks. An automated closed system reduces exposure to chemicals and enhances employee health and safety.1

The trophon family of devices includes trophon® EPR and trophon2 which share the same core technology of sonicated hydrogen peroxide.
