The introduction of a color liquid–crystal display (LCD) on a novel artificial pancreas (STG-55, Nikkiso Co. Ltd. Tokyo, Japan) allowed nurses to more easily monitor changes in patients’ blood glucose levels, compared to the previous model (STG-22). This study was conducted to examine the hypothesis that the STG-55 provided nurses with a feeling of security due to the introduction of the LCD screen. A questionnaire survey was conducted 6 months after the STG-55 was introduced (Survey 2012), among intensive care unit (ICU) nurses who had used both the STG-22 and the STG-55 for patient glycemic control. The results were then compared with the results from a questionnaire survey that was conducted after the STG-22 was introduced (Survey 2006). All ICU nurses (n = 19) responded to Survey 2012, and 95 % of these nurses had responded to Survey 2006 (n = 19). After the introduction of the STG-22, 11 nurses (58 %) reported becoming conscious of anxiety regarding hypoglycemia when they performed conventional glucose control with the sliding scale method. This anxiety awareness increased significantly (19 nurses, 100 %; p < 0.01) after the STG-55 was introduced. However, there were no significant differences in the proportion of respondents who requested improvements in the blood withdrawal process. In conclusion, the results of our survey indicate that all ICU nurses became conscious of anxiety regarding the risk of hypoglycemia when using the conventional sliding scale method after the introduction of the STG-55. However, the respondents were not satisfied with the STG-55, due to difficulties encountered during blood withdrawal.
