Infection Control & Reprocessing
The Spaulding classification in full, why it governs bench work as much as clinical use, and re-disinfection before return to service.
Any reusable patient-contact equipment a BMET services has a reprocessing classification - the Spaulding classification, first proposed in the 1960s and still the working standard - that determines the minimum cleaning standard before it can be touched for repair, and before it returns to clinical use.
The three tiers
- Critical items - contact sterile tissue or the bloodstream (most surgical instruments, implants) - require sterilization, the complete elimination of all microbial life including spores.
- Semi-critical items - contact mucous membranes or non-intact skin (most flexible endoscopes) - require at minimum high-level disinfection, which eliminates all microorganisms except high numbers of bacterial spores.
- Non-critical items - intact skin contact only (most monitor cables, BP cuffs, stethoscope diaphragms) - require low-level disinfection.
Why this governs bench work, not just clinical use
The same classification that determines how a device is cleaned between patients determines what state it needs to be in before a technician opens it up for repair. A semi-critical device arriving at the bench without having gone through appropriate reprocessing first is a real occupational-exposure risk to the technician, independent of whatever the device's eventual patient-facing use will be. Always confirm the reprocessing step happened before bench work begins.
Re-disinfection before return to service
After a repair, the device needs to go through the appropriate reprocessing step again before returning to clinical use - bench work itself (hands, tools, the bench surface) reintroduces contamination risk even to a device that arrived clean. This is a real infection-control control point, not a courtesy step, and it belongs in the repair checklist the same way a functional re-test does.
