Critical pathways are healthcare management plans that specify patient goals and the sequence and timing of actions necessary to achieve these goals with optimal efficiency. More than 80% of hospitals in the United States use critical pathways for at least some of their patients. Unfortunately, critical pathway effectiveness in improving clinical efficiency is unclear. ⋯ Although some pathways did reduce LOS or resource utilization or both, most pathways reduced neither. Because substantial resources must be expended on pathway development, implementation, and maintenance, future efforts should be placed on further evaluating the effectiveness of critical pathways and understanding the reasons behind their success or failure before additional resources are consumed for this management strategy.
