Exploratory analysis using discrete event simulation modelling of the wait times and service costs associated with the maximum wait time guarantee policy applied in a rheumatology central intake clinic

Adherence to wait time benchmark targets for the diagnosis and initiation of interventions rheumatoid arthritis is crucial in altering disease trajectory. We analysed impact maximum guarantee (MWTG) policy routing referrals initial rheumatologist consults on waiting service costs. modelled a central intake system rheumatology clinic as discrete event simulation (DES) model. Using data from input model system, we simulated arrival visits patients. demonstrated referral performance compared costs an MWTG first-available-appointment scenarios. option management strategy but comes with essential cost considerations. Healthcare managers policymakers should consider DES approach support decision choices.
