Challenges • • High patient service times High provider fatigue due to high patient volume and extended hour of service Opportunities • • Reduce service time without compromising LVPEI’s high standard of quality care Increase capacity without compromising LVPEI’s high standard of quality care Team Approach 4 Pre-trip (January to March) On-site (Mid- to late- March) • Engaged Sashi Mohan, Head of Operations, and Raja Narayan, Head of Clinical Services at LVPEI, over Skype • We interviewed key personnel at hospitals in the Boston area, including operations leaders at Massachusetts General Hospital (MGH) and practitioners at Massachusetts Eye and Ear Infirmary (MEEI) and Mount Auburn Hospital • Conducted time and motion studies in two cornea and two retina OPD clinics, collecting timestamps on the flow of patient folders, and noting management practices • Interviewed faculty ophthalmologists and optometrists, and OPD scheduling administrator • Conducted patient surveys at the walk-in counter Post-trip (April to May) • Ran statistical analyses to quantitatively identify relationships between different variables and patient service times • Compared findings to our interviews and observations of management practices • Derived recommendations for addressing systemic causes of increases in patient service times in the OPD GENERAL OBSERVATIONS 5 Patient pathways varied significantly depending on the clinic, and on the type of patient and appointment. Consultation Work-up Retina Check-In Retina Consultation Dilation 30 minutes Yes No Dilation required? Yes Dilation 30 minutes Cornea Consultation Check-out Investigations units are subject to their own process flow management practices. Investigation required? No Start Cornea Retina Investigation Yes Work-up 6 Investigation Cornea Investigation End Additionally, several combinations of factors impact patient service time. Hospital-Specific Factors • Commitment to training medical staff • Patient volume vs.. hospital capacity Scheduling-Specific Factors • Doctor-specified appointment and walk-in templates • Administrator's adherence to doctor-specified appointment templates • Real-time prioritization of patients Clinic-Specific Factors • Management of patient folders and staff • # of Fellows, Optometrists, and Facilitators • Skill levels of staff • Size and layout of clinics • Anticipated vs.. actual patient volume • Types and variety of patients that can be seen • Need for diagnostics Patient-Specific Factors • Lack of awareness of appointment-based system • Bias for early morning arrival • High volume of late arrivals and no shows 7 There is little discrepancy in patient service time between nonpaying and general patients, but high variability ranging from two to four hours.

Walk-in Survey Results Summary Survey Findings 40 patients surveyed in total • 41% of patients had tried unsuccessfully to make an appointment; 50% of these were because the requested appointment time was unavailable • 80% of patients who did not make appointments were unaware of the option • In general, awareness of the appointment option is low • Patients choose the walk-in option because the next available appointment is too far away • The majority of walk-in patients are new to LVPEI Interview Findings • Doctor scheduling for walk-in patients by time and type is often not adhered to due to over demand and incorrect triage • Unexpected walk-ins are disruptive to the patient flow, but doctors have no choice but to accommodate • Incorrect triage results in re-routing patients to other clinics and increased service time • Walk-in patients often have primary care concerns that do not require specialized attention, or ask to see a specific doctor unnecessarily Ideas to Consider 12 • • • • Better promote appointment system, especially among new patients Designate general doctors for walk-in clinic to reduce specialist time on general cases Require referral letters for new patients asking to see a specific doctor Enforce ophthalmologist-set guidelines for appointment booking at the walk-in counter Identify factors contributing to decreasing service times in the late afternoon. Apt.

If positive behavior is identified, this practice should be replicated during the rest of the day. 13 Monitor practitioner fatigue in latter half of workday, as high pressure to serve customers can lead to increased errors and reduced service quality. Interview Findings • Error rate of providers rises throughout the day for both optometrists and ophthalmologists • After 4:00PM, doctors begin to observe fatigue in their teams • After 4:00PM, doctors begin to observe work being completed in a hurry 4:22 Apt. Based Patients Arrivals & Service Times (all clinics) 3:53 3:24 2:55 2:26 1:58 1:29 Key Observations • Patients who arrive later in the day and patients who arrive significantly late for their appointments tend to experience lower service times. • Average service time decreases with time of day • With time of day, providers and staff tend to get fatigue and are prone to mistakes/errors 1:00 Service Pressure vs.. Time per Patient Time per Patient Ideas to Consider • Closely observe the error rate that is created at any given time • Closely observe the frequency of re-work over a given time period • Determine the cause of the decline in service times during latter half of the day 14 10am 1pm Time of Day 4pm Monitor practitioner fatigue in latter half of workday, as high pressure to serve customers can lead to increased errors and reduced service quality. Insights • Workday is scheduled for 8am – 5:30pm. Providers observed working until 7/8pm to service all patients • High patient backlog increases pressure on LVPEI providers to service all patients in a given day • Latter part of the day has been observed (via interviews) to increased fatigue and errors in service • High pressure situation coupled with long workdays will lead to high turnover of staff Perception of Long Wait Times at LVPEI Rate of Change in Perception about Wait Times + Perception Buildup Time Walkin Patients Apt.

Workday for Past Month Fatigue Buildup time Ideas to Consider • Adherence to apt. based system and reducing number of walk-in patients • Consider provider/staff rotation between highpressure clinics and regular clinics • Identify rework and errors created by time of day 15 Modeling Next Steps • Consider long term impact to quality of service and reputation due to high service times and errors/rework • Identify impacts to staffing and turnover due to high pressure environment • Consider competitor/alternate emergence scenario Identify and encourage best cross-consultation management practices Relevant Clinic Observations • Cross-consultation cases comprise a non-negligible percentage in each clinic: 10 to 15% • 3 out of 4 clinics employed practices to manage and integrate cross-consultation cases into existing patient flow • Management of cross-consultation cases differed across clinics • Passive cross-consultation management was disruptive to regular patient flow Sample Cross-Consultation Management Practices • Fixed time allocation: 15 minutes every 2 hours for cross-consultations and short follow-ups • Real-time prioritization: integration and prioritization of cross-consultations with existing patients • Prioritization by check-in: prioritization of cross-consultation patients according to check-in time • • • • 16 Ideas to Consider Conscious management of cross-consultation patients in each clinic Identification of good cross-consultation management practices Closer observation of the decision-making process behind the need for cross-consultation Guidelines for providers on the necessity for cross-consultation Remove annual post-surgery follow-up requirement and divert patients to comprehensive clinic for ongoing long follow-ups Observations • • • • 60-70% of doctor’s appointment templates are dedicated to seeing new patients 20% of all patients seen across the four days of study are new patients. Providers perform over 500 surgeries a year All patients are requested to come back for follow-ups at least once a year regardless of the need. Insights Surgical Case Fraction NS Patient Dep Rate Total Addressable Market Adoption Rate LVPEI Non-Surgical Patients + Surgery Rate B Hotel California + New Patient Arrival Rate + LVPEI OPD Patient Backlog Patient Service Rt. Follow Up Patient Arrival Rt 17 - Follow Up Appointments • Continuing with the policy of requiring patients to come back for simple follow ups exhausts LVPEI doctors’ capacity to serve new patients. • Dedicating more of providers’ time to follow up patients reduces opportunities to learn from diverse and complex cases. • Ongoing reduction in time available to see new patients limits LVPEI’s ability to realize its vision to reach all those in need. Ideas to Consider • Removing the requirement for all patients to come in for yearly follow-ups post-surgery • Transitioning fully recovered patients to comprehensive clinic for ongoing long follow-ups + New Patient Appointment Slots LVPEI Post Surgical Patients SG Patient Dep Rate + NEXT STEPS 18 Additional studies and modeling exercises will build a comprehensive understanding of the factors contributing to patient service time in the OPD. Future Studies • • • • • • • Time and motion studies that include cross consultation patients Time and motion studies on cornea diagnostics Patient flow of patients before they get to clinics Triage process at the walk-in counter Patients returning to LVPEI due to incorrect diagnosis Effectiveness of short-term recommendations Identification of best practices in clinic management Simulation Models • Additional data collection needed to quantify key relationships • LVPEI’s patient flow system for cornea and retina clinics 19 QUESTIONS? 20 APPENDIX 21 Monitor practitioner fatigue in latter half of workday, as high pressure to serve customers can lead to increased errors and reduced service quality.
