Chemotherapy Appointment\nScheduling Process Redesign:\u003Cem\u003E \u003C\/em\u003EManual booking\npractices\u0026nbsp;in place at the start of this study limited effective demand\nmanagement and\u0026nbsp;resulted in last-minute\u0026nbsp;rescheduling\u0026nbsp;of\nappointments.\u0026nbsp; The consequence of this\nwas heightened stress for patients and staff and operational challenges for the\npharmacy and outpatient clinics.\u0026nbsp;The implementation in June 2011 of more\nflexible booking\u0026nbsp;procedures combined with a custom-built computerized\nscheduling program based on a multi-criteria discrete optimization model, has\nalleviated these\u0026nbsp;problems by providing a reasonable timeframe to notify\npatients of their appointments.\u0026nbsp; This has\nreduced unnecessary changes to pre-booked appointments, supported\nthe\u0026nbsp;complex task of organizing the\u0026nbsp;daily treatment schedule and\nbalanced nurse\u0026nbsp;and pharmacy workload.\u0026nbsp;\n\u003C\/p\u003E\n\n\n\n\u003Cp\u003E2. Dynamic Radiotherapy (RT) Appointment Scheduling:\u0026nbsp; This research sought to develop good policies\nfor the dynamic scheduling of patients for radiation therapy.\u0026nbsp; A unique feature of this problem is that\nscheduling a patient means committing capacity over a course of treatments that\ncan range from 1 to 28 days depending on cancer site and treatment\nprotocol.\u0026nbsp; Further patients differ with\nrespect to the degree of urgency for their treatment and which RT machines can\ndeliver their therapy.\u0026nbsp; The practical\nproblem motivating the research involved scheduling 11,000 patients per year on\n9 RT machines. To address it, we formulated and solved a discounted\ninfinite-horizon Markov decision process (MDP). We used an affine architecture\nto approximate the MDP value function and solved an equivalent linear\nprogramming model through column generation to obtain an approximate optimal policy\nfor this problem. The benefits of the proposed method are evaluated by simulating\nits performance for a practical example based on data provided by the BCCA in\nwhich relative costs of delays were assessed by RT professionals.\u0026nbsp; We hope this research will provide the basis\nfor development of a scheduling application. \u003C\/p\u003E\n\n\u003Cp\u003ECo-authors\ninclude Antoine Saure, Jonathan Patrick, Scott Tyldesley, John French, Pablo\nSantibanez, Ruben Aristizabal, Vincent Chow, Kevin Huang and Nancy Runzer\u003C\/p\u003E\n\n\n\n\u003Cp\u003EBio:\u003C\/p\u003E\n\n\u003Cp\u003EMartin\nL.
