This trial is conducted in the United States of America (USA). The aim of this trial is to examine whether nurses prefer to use the NovoFine® Autocover Needle or the BD Safety Glide (TM) Syringe (only) in a hospital setting. The number of needle stick injuries will also be evaluated and whether these hospital nurses prefer the safety features of the NovoFine® Autocover Needle versus those of the BD Safety Glide (TM) Syringe. The identified hospital nurses will evaluate the two types of needles during standard administration of insulin to patients being treated for diabetes.
