Round robin tests conducted by the working group DaVinci («AG DaVinci») to establish a method for testing the cleaning of MIS robotic instruments

Abstract
In order to quantify the cleaning efficacy for MIS robotic instruments after reprocessing, the working group DaVinci established two methods to elute residual protein soil from robotic instruments and to subsequently quantify it [1]. While developing the methods, round robin tests were conducted and recovery rates were quantified using a model protein (bovine serum albumin, BSA, Fraction V) as well as reactivated sheep blood as test soil. The amount of test soil applied was between 200 - 500 µg protein, referred to bovine serum albumin (BSA), and thus within a critical range to the acceptance level for reprocessed instruments. The recovery rates determined using a clinically relevant test soil of reactivated sheep blood were on average 96 % (non-destructive elution method), or 83 % (destructive elution method). For protein quantification, the modified ortho-phthaldialdehyde (OPA) method [2, 3], as well as the bicinchoninic acid (BCA) method [4] were used. Both methods provided comparable results. However, for both methods influences were observed that were attributed to interfering substances from the instruments. Methods to remove these interfering compounds from the eluates could not be established yet. Experimental series conducted by single laboratories showed that recovery rates were in good match for varying amounts of test soil ranging from 100 - 1000 µg per instrument. Applying the described methods recovery rates showed a good correlation between the participating laboratories, taking into account the complexity of the medical devices analyzed.

FROM THE FIELD

A. Ungänz:
Need and feasibility of cost control for instrument reprocessing in the outpatient setting

Abstract
This paper entitled «Need and feasibility of cost control for instrument reprocessing in the outpatient setting» reports on a study carried out in Bad Kreuznach between 10 June 2013 and 11 October 2013 as part of the qualifying process as Technical Sterilization Assistant on completion of Specialist Training Course III. The main focus of the study was analysis of the costs incurred for instrument reprocessing in outpatient medical/dental practices. Up till now there has not been any concrete information available to put a figure on the costs incurred by such medical/dental practices when reprocessing the various instruments. Hence it was not possible to compare prices or find single-step solutions. This paper now closes that gap. Using a software program that was developed in the course of the project, the costs incurred for reprocessing instruments with different processes can be documented and evaluated. The cornerstone of this calculation is exact registration of all aspects of reprocessing for which costs are incurred, such as for example personnel costs, equipment costs, energy costs as well as fixed costs and overhead costs. The complexity of the cost structure is simplified thanks to this newly developed software. The medical/dental practices using this software need only enter the prices and costs known to them. This information is then processed by the software using complex mathematical formulas and output as exact results. The data are broken down and displayed for different periods of time, e. g. as daily, weekly, monthly or annual costs, and this makes it easier for the medical/dental practice to manage its business activities. The overall reprocessing costs incurred for the example described in this paper was 19,019.64 €, which amounted to daily costs of 74.34 €.
