A Honor Society of Nursing (STTI) answered. The rate of incidence for pancreatitis each year in the United States is over 300,000 people. Roughly 200,000 people are hospitalized each year for treatment of acute pancreatitis.
As reported in Diabetes Technology & Management, recent research shows that smaller 8 millimeter (mm), 6 mm, and 4 mm needles are as effective, regardless of body mass. This makes insulin injections more acceptable and less painful than it was in the past.
Some insulin pens contain a cartridge of insulin that is inserted into the pen and some are pre-filled with insulin and discarded after all the insulin has been used. The insulin dose is dialed on the pen, and the insulin is injected through a needle, much like using a syringe. Cartridges and pre-filled insulin pens only contain one type of insulin. Two injections must be given with an insulin pen if using two types of insulin.
