Design outcomes

Primary

MeasureTime frameDescription
The Relative Ease of Use of NordiFlex® Compared to the Device Previously UsedWeek 6Analysed for the ITT (intent-to-treat) analysis set: The relative ease of use of the trial injection device compared to the device previously used was assessed using a quantitative scale, ranging from 0 to 10 with 0 = NordiFlex® is far less simple, 5 = equivalent simplicity and 10 = NordiFlex® is far more simple. The participants had to circle the number that represented their perception of the current state.

MeasureTime frameDescription
Percentage of Participants Evaluating Simplicity of Use: Dose ModificationWeek 0The overall simplicity of use was evaluated at every step of the injection preparation (dose selection, injection and dose modification) and using the time spent in the preparation of the injection. Ordinal variables were used for the evaluation (very easy, easy, fairly easy, difficult and very difficult).
Percentage of Participants Evaluating Simplicity of Use: Injection EasinessWeek 0The overall simplicity of use was evaluated at every step of the injection preparation (dose selection, injection and dose modification) and using the time spent in the preparation of the injection. Ordinal variables were used for the evaluation (very easy, easy, fairly easy, difficult and very difficult).
Percentage of Participants Evaluating Simplicity of Use: Time Spent in the Preparation of the InjectionWeek 0The overall simplicity of use was evaluated at every step of the injection preparation (dose selection, injection and dose modification) and using the time spent in the preparation of the injection. This was evaluated using time intervals: below 5 minutes, 5-10 minutes, 10-20 minutes.
Ease of Learning Assessed by the Physician or the Nurse: Ease of TrainingWeek 6The person in charge, physician or nurse, of giving all the instruction of use to patients or parents assessed the ease of learning of the Nordiflex® device. Ease of learning was evaluated using ordinal variables (very easy, easy and difficult).
Percentage of Participants Evaluating Simplicity of Use: Dose Selection EasinessWeek 0The overall simplicity of use was evaluated at every step of the injection preparation (dose selection, injection and dose modification) and using the time spent in the preparation of the injection. Ordinal variables were used for the evaluation (very easy, easy, fairly easy, difficult and very difficult).
Ease of Learning Assessed by the Physician or the Nurse: Added Values of the ProductsWeek 6The person in charge, physician or nurse, of giving all the instruction of use to patients or parents assessed the ease of learning of the Nordiflex® device. An added value of device was evaluated by the physician or the nurse using categorical variables.
Patient Autonomy: Percentage of Patients Performing Operations for Treatment InjectionWeek 0The patient autonomy was evaluated using percentage of participants who performed all the operations of the treatment administration including dose selection, dose modification in case of error and injection.
Patient Preference: Percentage of Participants Preferring System for Continuation of Growth Hormone TreatmentWeek 6The patient preference was evaluated using the percentage of participants preferring the new system, old system or none of them for their growth hormone therapy.
Number of Participants Reporting Adverse Events, Medical Events of Special Interest (MESI) and Technical Problems With Devices Used in TrialWeeks 0 - 6
Ease of Learning Assessed by the Physician or the Nurse: Time LearningWeek 6The person in charge, physician or nurse, of giving all the instruction of use to patients or parents assessed the ease of learning of the Nordiflex® device. Time to learning was assessed using time intervals: 6-10 minutes, 11-15 minutes, 16-30 minutes and 31 minutes to 1 hour.

Participant flow

Recruitment details

The trial was conducted in France (38 sites). Recruitment period occurred from 17-Nov-2010 to 18-Apr-2011.

Pre-assignment details

Eligible participants had to receive training for the use of Nordiflex® system. A member of the investigator's team, physician or nurse, was in charge of this training. At inclusion and before receiving treatment, participants or parents had to complete a questionnaire about the ease of use of the previously used device.

Outcome results

Primary

The Relative Ease of Use of NordiFlex® Compared to the Device Previously Used

Analysed for the PP (per protocol) analysis set: The relative ease of use of the trial injection device compared to the device previously used was assessed using a quantitative scale, ranging from 0 to 10 with 0 = NordiFlex® is far less simple, 5 = equivalent simplicity and 10 = NordiFlex® is far more simple. The participants had to circle the number that represented their perception of the current state.

Time frame: Week 6

Population: Per protocol set (PP): All subjects in the ITT set using NordiFlex® and had completed the trial without any significant violation of the inclusion/exclusion criteria or any other aspect of the protocol considered to potentially affect the efficacy results.
