Most hospitals have centralized phlebotomy where the phlebotomist is dispatched from the laboratory to collect blood samples. Having a phlebotomist with a single job helps the other medical staff focus on their own tasks at hand. Often times with this there can be no work for the phlebotomist and in other instances there is more work than can be done in the time period given. Decentralized phlebotomy, not as common as centralized phlebotomy, is where more people are collecting blood samples when it is busy. This makes it simpler than hiring a phlebotomist who is not always needed because you can use the people who are already there. The con is that studies show with decentralized phlebotomy there is more errors.

Discuss the pros and cons of a hospital having centralized or decentralized phlebotomy.
