title: Assessment of user-friendliness of the Norditropin FlexPro for pediatric patients treated with recombinant human growth hormone: results of an open-label user survey.
abstract: OBJECTIVE
  To assess the user-friendliness of the Norditropin FlexPro (Novo Nordisk A/S, Bagsvaerd, Denmark), a newly developed growth hormone (GH) injection pen.
  
  
  METHODS
  This study consisted of a single-center, single-arm, open-label, questionnaire based survey of patients undergoing GH treatment for diverse indications who were scheduled to switch from the formerly used device Norditropin NordiFlex (Novo Nordisk A/S) to the FlexPro and evaluate each device's usability.
  
  
  RESULTS
  A total of 82 patients participated in the study. Compared to the NordiFlex, the FlexPro was regarded as easier to grip, easier to hold during injection, and more stable during injection. The degree of pain at insertion perceived by the patient and the patient's fear of injection were significantly decreased when using the FlexPro, and 81% of the respondents selected the FlexPro as the more preferable device.
  
  
  CONCLUSIONS
  The FlexPro was more user-friendly than the NordiFlex. Perception of pain at insertion and fear of injection were lessened by using the FlexPro.
