The orthopedics clinic at an academic medical center has low patient satisfaction rates for patients that require an X-ray and have difficulty ambulating. The project aimed to reduce the 'non-value-added' time during appointments by using Lean and Six Sigma methodologies and enhance patient experience.INTRODUCTIONThe orthopedics clinic at an academic medical center has low patient satisfaction rates for patients that require an X-ray and have difficulty ambulating. The project aimed to reduce the 'non-value-added' time during appointments by using Lean and Six Sigma methodologies and enhance patient experience.An analysis of the current state was conducted using Gemba walks, interviews with subject matter experts and an interrupted time study to assess baseline data. The project was implemented using a three-phase Kaizen event approach.METHODSAn analysis of the current state was conducted using Gemba walks, interviews with subject matter experts and an interrupted time study to assess baseline data. The project was implemented using a three-phase Kaizen event approach.Interventions implemented included: (i) re-engineering patient flow and (ii) standardizing appointment scheduling guidelines. The 'non-value-added' appointment time was measured post-intervention and it decreased from 17 to 8 min (51%), and 87% (N = 47) of patients rated the scheduling process positively.RESULTSInterventions implemented included: (i) re-engineering patient flow and (ii) standardizing appointment scheduling guidelines.
