11 + Analyze Define Measure Analyze ImproveControl

12 + Possible reasons (selected) Unnecessary stations Unnecessary / overdoing investigations (over- processing) Unpredictable workload Huge patient load Clinic design for patient flow

13 + Waiting time for VA

14 + Waiting time for doctors consultation

15 + Waiting time for Appointment booking

16 + Improve Define Measure Analyze Improve Control

17 + What have we done for the bottleneck (TOC) - VA? Leveling Quota for VA / no VA for each time slot DA FU checklist Decide what investigations to be done next visit before seeing doctor Major change of work pattern in many parties! TL clinic Add 1 ECA VA only if necessary Change of optometrist break time (prn)

18 + What have we done for the bottleneck (TOC) - VA? Enhanced IT system for appointment booking Allow checkbox for investigations next visit

19 + Other improvements OT appointment counter help booking next appointment Less one station for patients OT appointment staff take up PM DSC admission Free up one more appointment staff at 11 am

20 + Other improvements MP allergy data entry into record Risk management Drug payment Kiosk (Finance) Less one station for patients Nursing / ECA staff help promote Utilization rate now 18.9%
