[Excerpt from publisher] In 2004, representatives from the Canadian Nurses Association (CNA), the Canadian Practical Nurses Association (CPNA), the Canadian Council for Practical Nurse Regulators (CCPNR) and the (RPNC) developed an evaluation framework to determine the impact of nursing staff mix decisions. The framework was based upon a literature review and was finalized after incorporating feedback from a national consultation (CNA, 2005). It will evolve with additional experience and research. It is anticipated that this framework will enable employers to determine how effectively they are using their nursing resources. This project is one component of a larger initiative, funded by Health Canada, to further develop selected recommendations from the Canadian Nursing Advisory Committee's final report, Our Health, Our Future: Creating Quality Workplaces for Canadian Nurses (2002).
