Senior Design, Spring 2001 Pediatric Dental Office Simulation: Patient Scheduling System Presented By: Erin Hopper Meagan Simmons Abby Sly

Senior Design, Spring 2001 The Problem Dr. Roy Green of Ft. Myers, Florida approached our team to evaluate the efficiency of his current block scheduling system with regards to:  Chair Idle Time  Server Idle Time  Patient Waiting Time

Senior Design, Spring 2001 The Current Problem Scenario  Patient Volume  Staff Resources  Chair Use  Procedure Distribution (Dr. Hours)

Senior Design, Spring 2001 The Current Problem Scenario: Categorization of Procedures RC : Regular Check-up OP : Regular Restorative PM: Oral Sedation IM : Intra-muscular Sedation

Senior Design, Spring 2001 The Current Problem Scenario: Block Scheduling  Horizontal  Treatment Dependent  Deterministic  Dynamic

Senior Design, Spring 2001 Block Scheduling Example

Senior Design, Spring 2001 Approach to Problem Using ProModel simulation software, we created the current block scheduling system used by Dr Green’s practice.

Senior Design, Spring 2001 Assumptions in Model Creation  Patient Arrival  Staff Behavior  1/1/1 Ratio  Independent Sessions  Emergencies

Senior Design, Spring 2001 Influential Historical Data  Variability within Procedure Time  Variability due to Dentists  Distribution of No-Shows

Senior Design, Spring 2001 Results of Current Scenario: Chair Idle Time

Senior Design, Spring 2001 Results of Current Scenario: Resource Idle Time

Senior Design, Spring 2001 Results of Current Scenario: Patient Wait Time 93.45% 13.28%

Senior Design, Spring 2001 Sensitivity Analysis: 3 Scenarios  Scenario (1): Addition of an Extra Dentist  Scenario (2): Addition of an Extra Chair  Scenario (3): Addition of both an Extra Dentist and Chair

Senior Design, Spring 2001 Results of Varying the Model:

Senior Design, Spring 2001 Recommendations Best Scenario: ADD A DENTIST Decrease in Dentist Idle Time Decrease in Chair Idle Time Decrease in Patient Waiting Time

Senior Design, Spring 2001 Critiques Account for: Patient Volume Pediatric Dentist Duties Appointment Call-In Procedure

Senior Design, Spring 2001 Conclusions We feel our recommendation of incorporating another pediatric dentist in Dr. Green’s practice will improve the quality of patient care while increasing profitability.
