Primary Outcome Measures:
  • Evaluation of test case scenarios with observation and performance measures [ Time Frame: 8 days ]
    Test case scenarios were designed to determine if the potential risks associated with the use of the prefilled pen were mitigated by information contained in the patient leaflet and the training provided to each patient or caregiver. The test case scenarios with observation and performance measures will be evaluated.
