Table 4 Example of a question in the DCE

In order to help improve the quality of the theatre environment for laparoscopic surgeons it is important to understand which features of laparoscopic theatres are valued and which are not valued.

In the next set of questions you will be asked to choose between two different theatre configurations. Although the options may seem contrived please try to choose between the options in an honest way as this will help to evaluate the options.

Please choose option A or B.

Option A.

The screens and stacks are floor mounted.

The screens are not adjustable for height, angle or position.

The C02 is in canisters.

The laparoscopy light, CO2 gas on/ off and room lights are controlled by the non scrubbed nursing staff.

There are wires on the floor and there is no external transmission of the images.

Option B.

The stacks and screens are ceiling mounted and fully adjustable for height, angle and position.

The CO2 is piped (continuous) and the sterile personnel (surgeon or scrub nurse) can control the laparoscope light, CO2 gas on/off and the overhead room lights.

The floor is wire free and the there is external transmission of video set up.
