It has been found that medical and nursing staff, have limited knowledge about insulin and how to adjust doses. To aid education of hospital staff about insulin action, a tabletop tool was designed to provide a hands-on, visual aid to be used in workshop style education. Two diabetes educators experienced in insulin stabilisation presented the workshop to 25 junior medical officers. The session began with; information on insulin regimens, insulin action profiles and the relationship of insulin to carbohydrate intake. Participants were then divided into two groups, each group gathered around a table with a diabetes educator and a table-top tool at each table. The tool shows a time-line of hours of the day and is overlaid with pictures representing meals and snacks. There are a number of schematics of insulin action profiles on clear plastic that can then be overlaid and moved around on the tool. The group is then better able to visualise insulin onset, peak action and duration in relation to time of day and carbohydrate intake. Clinical cases were discussed and participants moved the profiles around discussing options for insulin adjustment. There was a pre and post workshop knowledge test, and an evaluation questionnaire. Results: At the end of the workshop, there was increased knowledge about insulin onset, peak action and duration times. Participants reported that their knowledge had improved and the tabletop tool was very helpful. The presenting educators believed that the workshop was effective but groups should be limited to eight participants per table with follow up workshops. Conclusion: Interactive workshop tutorials using a hands-on visual aid are helpful in teaching hospital staff about insulin. Follow up workshops of smaller groups of up to eight participants are recommended.
