Trepidation: a family member's response to shift change in the intensive care unit.

Every shift change in the intensive care unit presents an opportunity for uncertainty among family members regarding rules and information exchange. High levels of uncertainty maintain a presence in the intensive care unit environment, and feelings of trepidation can increase with uncertainty. Critical care nurses in the intensive care unit play a pivotal role in mediating family members' feelings of trepidation by what they do or do not do. Further research into family members' responses to shift change and into inconsistencies in nursing decisions regarding rules and information exchange in the intensive care unit is needed to better understand the feelings that family members experience in the intensive care unit environment and to motivate meaningful changes that will contribute to a clearer sense of purpose for family and their loved ones.
