Summary: Instrument trays revised
A research into the benefits of alternative trays compositions for
the surgery department in the Medisch Spectrum Twente
Pieter Wolbers
Abstract
Instrument trays hold sets of instruments used during surgery. Some
trays are specifically matched to particular procedures. However, most
trays hold large instrument sets that are used by a wide range of proce-
dures. Regardless of the number of instruments available from the tray
that are actually used during surgery, the complete content of the tray
has to be (re-)sterilized afterwards. By more closely matching the content
of instrument trays to the procedures they are used for, sterilization costs
might be reduced drastically. In this research we define a methodology
for minimizing the number of sterilizations per year. We therefore change
the composition of some frequently used instrument trays. This research
is performed in the Medical Spectrum Twente and focusses on 11 surgi-
cal procedures of the surgery department. We reallocate the instruments
currently used for these procedures by using an LP model. We estimate
the savings that can be realized when reallocating instruments for a par-
ticular set of procedures. We expect the costs can be reduced by at least
