The cost of being clean: A cost analysis of nasopharyngoscope reprocessing techniques

Objective

Nasopharyngoscopes are an essential instrument to otolaryngologists; reprocessing them in a high-value manner is paramount. Although several different techniques for reprocessing exist, all methods yield similar effectiveness. Given equivalent effectiveness outcomes, a cost analysis of four nasopharyngoscope reprocessing techniques was performed.

Study Design

Cost-minimization analysis.

Methods

Four techniques were evaluated: 1) an automated reprocessor using peracetic acid (Steris System 1; Steris Canada Inc., Mississauga, Canada), 2) an automated reprocessor using ortho-phthalaldehyde (OPA) (Cidex OPA; Advanced Sterilization Products, Johnson and Johnson Inc., Markham, Canada), 3) a manually performed accelerated hydrogen peroxide bath (Revital-Ox; Steris Canada Inc.), and 4) a chlorine dioxide wipe (Tristel Trio Wipes System; Tristel plc, Cambridgeshire, U.K.). The costing perspective was a third-party payer that was adjusted to 2014 Canadian dollars. The base-case scenario used an annual volume of 4,153 reprocessing events in a tertiary care setting, and a scenario analysis assessed the impact of volume and capital expense.

Results

The cost per reprocessing event for the Steris (Steris Canada Inc.) automated endoscope reprocessing, Cidex OPA (Advanced Sterilization Products), Revital-Ox (Steris Canada Inc.), and Tristel Trio Wipes (Tristel plc) were $20.58, $14.20, $9.57, and $13.14, respectively. Scenario analysis demonstrated the Tristel Trio Wipes System (Tristel plc) was the least expensive method in practices with low reprocessing volumes (a threshold of less than 6 events per day, or 22 per week), whereas the Revital-Ox (Steris Canada Inc.) system was least expensive at higher volumes and became substantially more so as volumes increased.

Conclusion

A manual accelerated hydrogen peroxide bath offers the least costly approach to nasopharyngoscope reprocessing. The convenience and portability of the Tristel Trio (Tristel plc) system may be a good alternative for low reprocessing volumes, or when rapid turnaround is necessary.
