WINNIPEG A group of critical care nurses from the Health Sciences Centre Medical Intensive Care Unit (MICU) have penned a letter to the Manitoba government expressing their concerns regarding a new model of care that’s diluting nurse-patient ratios. According to the letter, which is addressed to Premier Brian Pallister and Health Minister Cameron Friesen, the usual model of care in the MICU is based on the Australian College of Critical Care Nurses’ (ACCCN) workforce standards for intensive care nursing. The nurses note this model of care is endorsed by the Canadian Association of Critical Care Nurses, is based on an evidence-based review, and was developed in collaboration with nurses.
