Lean Behind The Scenes: Sterile Processing
Sterile Processing runs a lean operation, delivering millions of instruments to 91麻豆天美直播鈥檚 procedural teams. Director of value engineering Steve Johnson, assisted by the video wizardry of Charlie Ehlert, sheds light on our system鈥檚 unseen infection prevention heroes.

A round 140 surgeries and other invasive procedures take place in our hospital system each week day 鈥 and at each one, a surgeon will walk into the operating room and find his or her instruments waiting. For surgeons, sterile instruments are like electricity or any other utility; a lean system is out there delivering what鈥檚 needed, where and when it鈥檚 needed, while remaining out of sight and out of mind.
This video and process map highlights the professionals of Sterile Processing as the stewards of our surgical instruments. An integral part of the system required to provide safe and efficient surgery, sterile processing is a much larger and more sophisticated operation than most understand.
LEAN PRACTICES IN ACTION
Sterile Processing鈥檚 lean operation employs a series of lean practices defined below.
1. FORCING FUNCTIONS
Forcing functions help us do the right thing for patients while reducing the cognitive load. A forcing function is a control in the process designed to prevent errors. Some forcing functions are process steps requiring conscious consideration of the process (e.g. an OR time-out) while some are error-prevention mechanisms (e.g. a three-prong plug).
2. DOCTOR PREFERENCE CARDS (CHECKLISTS)
A common forcing function to prevent the error of missing a step or, in this case, an item. Simple in concept but requiring multiple iterations to develop and discipline to use.
3. BARCODES
Another common forcing function to reduce the errors associated with more manual inventory tracking methods. Barcode scanning is fast, reliable, precise, and provides immediate feedback 鈥 鈥渂eep鈥 is good, 鈥渂ong鈥 is bad.
4. LAYOUT (AS FORCING FUNCTIONS)
Lean layouts are often agile, allowing adaptation to changing requirements. Indeed, much of Sterile Processing鈥檚 equipment is on wheels for this purpose. However, SP鈥檚 segregated layout ensures against contamination: instruments flow in a single direction from the dirty zone to the clean zone to the sterile zone.
5. JUST IN TIME (JIT)
Getting the right material and equipment into the right hands, at the right time, defect-free.
6. THE WASTE OF TRAVEL
Traveling from place to place doesn鈥檛 add value to the service we鈥檙e providing. Whether it鈥檚 the patient, staff, stuff, or information, travel should be minimized.
7. QUALITY CONTROL MECHANISMS
These mechanisms offer hard evidence that vital quality thresholds were met. For example, the required temperature was reached, or bacteria died. Quality control mechanisms tell us whether an error occurred after the process step; forcing functions prevent the error from occurring in the first place.
