text: Yo, digital health management, it's crucial for diabetes patients' arrangement,
  This review aims to assess smart insulin pens' clinical gains, no need for alteration.
  We searched PubMed and PubMed Central, May 15, 2019, the date,
  To find studies on insulin pens, connectivity, the key trait.
  
  Included studies had pens with Bluetooth or Near Field Communication,
  Or an electronic device for connectivity, or a memory function, no hesitation.
  Nine studies were found in this quest,
  But most focused on pens with memory, leaving us stressed.
  
  Patient preference, usability, and technical accuracy, they explored,
  But clinical outcomes were scarce, only three, they ignored.
  Yet, eight studies reported patients preferred smart insulin pens,
  Boosting confidence in self-management, a message that transcends.
  
  The lack of published data on connected smart pens is clear,
  But usability and patient preference show potential, have no fear.
  Smart insulin pens hold promise for simplifying and enhancing,
  Diabetes self-management, a future worth advancing.
