Building a Reliable Health Care System: A Lean Six Sigma Quality Improvement Initiative on Patient Handoff.

Background: There is limited evidence available identifying best practices to promote and sustain optimal outpatient-to-inpatient handoff processes to ensure safe and reliable continuity of care.

Local Problem: A sentinel event occurred during the transition of care from the outpatient-to-inpatient setting. A root cause analysis revealed that the facility's standard operating procedure for patient handoffs was not consistently followed.

Methods: A Lean Six Sigma approach was used to improve patient transfer with the implementation of a Situation-Background-Assessment-Recommendation handoff policy. Inferential and statistical process control methods were used to assess performance outcomes pre- and postdissemination.

Results: Over 36 months there was a slow, steady decrease in patient transfer time including reduced variability. The most significant improvement effect occurred in the third year with a 50% reduction in transfer time.

Conclusions: Longitudinal monitoring provides the opportunity to accurately identify beneficial outcomes, which develop downstream from initial quality improvement efforts.
