I am looking for information giving evidence to the value of training/educating Patient Care Assistants. Since many acute care facilities are abandoning the utilization of Licensed Practical Nurses as part of their staff, many of their duties are being taken over by PtCAs/Nursing Assistants. Have patient outcomes changed? Is there a high attrition rate among this population of nursing support staff? If so, what is the predominant reason(s) and what is being done to retain these employees?
