Nursing staff at both sites was asked to complete a questionnaire after recruitment had finished. These were the original formulations:
1. “How well was the patient’s blood glucose stabilised in the target range from 4.4 and 8.3 mmol/l?”
2. “Was your workload using Space TGC System reduced or increased?”
3. “Do you think that control of the patient’s blood glucose was maintained more effectively by the use of the Space TGC system compared with normal practice?”
4. “Is the Space TGC system user friendly?”
5. “Were there any problems with the use of the Space TGC system?”
6. “Did you feel confident using the Space TGC system?”
7. “Do you think that using the Space TGC system can help to avoid making mistakes when controlling the blood glucose?”
8. “Do you think that the Space TGC system may be a worthwhile tool for routine use in the ICU?”
9. “Did you trust the Space TGC system would maintain the blood glucose at a safe level?”
