Lean, derived from the Toyota Production System, is a process improvement methodology focused on reducing waste (steps that do not add value to the final service/product) to improve efficiency. Correspondence to Staff interviews, workshops, and review of patient complaint data were used to identify issues causing prolonged duration and increased variability of patient in-clinic time and clinic inefficiency. Consequently, they could control defects and boost hospital savings by up to $950,000 annually. This involved: moving the start time of screening staff and patient appointments to 7:30am so patients could be screened and ready to see the ophthalmologist at 8am; revising appointment slot time lengths to better align with the needs of each appointment type; creating dedicated on call emergency and inpatient appointment placeholders to reduce ad hoc scheduling of these patients; and providing the on-call registrar with a live scheduling app to allow easier identification of available appointment slots for ad hoc bookings. Itis a leading innovator in health and health care improvement worldwide. In this blog, well provide an overview of the Six Sigma methodology and explain how it can be applied to healthcare. A post-implementation audit was conducted, and the results compared with baseline audit data. Waiting time before check-in or after check-out (e.g. Do you have the necessary skills and resources? Thirdly, as the baseline audit was performed retrospectively, many patient visits had invalid data and were excluded from in-clinic time analysis (1383 of 3624 visits). Within the clinic there are three rooms for screening, three rooms for ophthalmologist review, two rooms for investigations and two rooms for procedures. Together, increasing patient numbers, increasing complexity of patient assessment and management, and limitations on healthcare resources have resulted in prolonged patient wait times, decreased quality of service, and decreased patient satisfaction in many outpatient services across many medical specialities in both developed and developing nations [2,3,4]. This is in accordance with other Lean and/or Six Sigma healthcare applications, in which standardisation was the second most commonly used quality tool . James E.H. Smith. Some of the more common tools are cause and effect diagrams(also known as the Fishbone diagramor Ishikawa diagram), driver diagrams,Failure Modes and Effects Analysis(FMEA),andPareto charts. visits with no end time or total duration of 0 or greater than 480 minutes) were included in the count of patients seen but excluded from analysis of duration and variability of patient in-clinic time. 2. 3a), most patients were scheduled to arrive in the middle of clinics (between 9:00am-10:30am for the morning clinic and 2:00pm-3:00pm for the afternoon clinic).
