The effect of dual policy interventions on the rate of central venous catheter associated infections in adult stem cell transplant patients with hematological malignancy in Newfoundland and Labrador
Background: Central venous catheters (CVCs) have a risk of infectious complications. With a suspected rise in cases in stem cell transplants, Eastern Health implemented two changes to reduce infections in June 2018: (1) earlier CVC insertion and (2) restriction of CVC access to specially trained nur...
