AIDA Interactive Educational Freeware Diabetes Simulator - Randomised Controlled Trial (RCT)

Randomised Controlled Trial (RCT)

The AIDA diabetes simulator has been tested out in a pilot randomised controlled trial (RCT). The protocol used for the RCT was described a priori in the medical / diabetes literature. The study sought to assess whether diabetes educational teaching sessions using the AIDA simulator led to better outcomes than similar diabetes educational teaching sessions without a computer. The study was run at the Ospedale di Marino, near Rome, in Italy by an independent diabetologist / endocrinologist – unconnected with the simulator's development. Twenty-four volunteers (12 male and 12 female) with type 1 diabetes of more than 6-years duration, aged 19-48 years, who gave written informed consent, were randomly assigned to one of two study groups, each receiving different teaching interventions. Group A was exposed to the AIDA diabetes simulator, while Group B (the control group) received conventional lessons with slides and transparencies. Six lessons were held for each group (one per week). At the beginning and end of the study all subjects had their glycated hemoglobin (HbA1c) measured. The subjects also carefully documented the incidence of any symptomatic hypoglycaemic episodes ('hypos'), whether mild (sweating, dizziness), moderate (nausea, vomiting), or severe (requiring assistance).

The results seem encouraging. HbA1c levels in Group A dropped significantly from 7.2% to 6.4% after lessons with the diabetes simulator (p = 0.01). No significant changes in HbA1c were observed in the control group (Group B) between baseline (7.1%) and the end of the control lessons (7.0%). The number of 'hypos' decreased significantly from 31 to 14 in Group A (p = 0.03) after AIDA lessons, but did not change significantly in Group B from baseline (n = 20) to after the control lessons (n = 22). Full details of the study and the results can be found in the medical / diabetes literature. The study authors concluded that "larger trials involving more patients in more centres are clearly needed, but this proof-of-concept (pilot) study does demonstrate the feasibility of using a prospective randomised controlled trial approach for the evaluation of educational diabetes simulation software such as AIDA".

Famous quotes containing the words controlled and/or trial:

    White men have always controlled their wives’ wages. Colored men were not able to do so until they themselves became free. Then they owned both their wives and their wages.
    Susan B. Anthony (1820–1906)

    For he is not a mortal, as I am, that I might answer him, that we should come to trial together. There is no umpire between us, who might lay his hand on us both.
    Bible: Hebrew, Job 9:32-33.
