Decreasing Length-of-Stay in Elective Neurosurgery: Success of a Quality Improvement Initiative

Le résumé fourni par la source

Purpose To describe the design, implementation, and the results of a longitudinal multidisciplinary quality improvement (QI) initiative to improve length of stay (LOS) in elective neurosurgical patients at an academic satellite hospital. Methods A comprehensive quality improvement initiative to decrease LOS in elective neurosurgery patients. LOS was measured on a per-patient basis using an individualized LOS Index (LOSI), defined as an observed-to-expected LOS ratio. Interventions were identified and implemented using QI methodology and results were tracked in real-time using Shewhart control charts over a 12-month period. Bi-monthly meetings with a multidisciplinary working group enabled continuous and iterative development, review and implementation of effective interventions. Notable interventions include standardizing electronic medical record (EMR) order sets to include Extended Recovery After Surgery (ERAS) components, standardizing physical therapy, social work and case management processes, streamlining radiology workflows, and standardizing interdisciplinary communication. Results The initiative led to a sustained reduction in LOSI, with several consecutive months surpassing the institutional target of <1, accomplishing the project’s primary aim. Furthermore, at the completion of the project there was a statistically significant improvement in LOSI from the pre- to post-intervention groups (1.13 vs. 0.93, p=0.033). Conclusion This initiative demonstrates that longitudinal, multidisciplinary QI efforts based on realtime analysis and data-driven adjustments can lead to impactful, sustained reductions in LOS for elective neurosurgical patients. Our initiative provides a sustainable and adaptable framework that may serve as a model for other institutions seeking to improve perioperative efficiency and patient care outcomes.
