Stop Wrong-site nerve blocks

Perform your time with EZCOVER®

Wrong-site nerve blocks (WSNB) are considered as “never events” in health care, yet they continue to occur and pose a risk of serious consequences.1 WSNB can harm the patient, increase treatment costs and lead to a loss of trust in the health care system. Medico-legal claims arising from WSNB are indefensible, and typically settle as a malpractice damage.2
