One good thing is that many certifying bodies will write a letter of advocacy to your employer. One main thing I would emphasize is that being a competent and knowledgeable wound clinician would save them TIME AND MONEY. No system wants to pay for their inmate to go OUT to be taken care of. It would also be of great assistance if you were ever called to testify regarding an injury or the care that was given to a wound. www.abwm.org www.wocnb.org
Both of these certifying bodies will write a litter of advocacy after passing the exam. However it sounds like you are wanting one before certifying. I would make sure to outline all the problems your system is currently having wound practices and then propose the benefit and change in procedure that would occur if the prison staffed a competent and certified wound nurse.
Not sure if that helped!
