Case 1: Dana-Farber Cancer Institute
The Dana-Farber Cancer Institute’s (DFCI) outpatient clinic is located in Boston, MA. DFCI is considered to be one of the best ambulatory cancer institutes in the world. Its repu- tation attracts approximately 1000 patients each day, who often must travel from around the globe for DFCI’s top-notch cancer treatment. Patient’s visit duration ranges from one hour (second opinion patients) to an entire day (chemotherapy infusion patients). The high volume of arriving patients requires an excessive process management initiative supported by state of the art information systems, process experts and data scientists. To this end, a year ago, the DFCI traded its local IT implementations for a single unified Process-aware Information System, named the EPIC. The EPIC is ‘best of breed’ when it comes to medical information systems. The EPIC includes the blood area module, the medication prescriptions production system, the appointment book, and the (E-)medical record (EMR).
The patient flow in DFCI is as follows. Patients arrive during morning hours (alone or escorted by family members). Patients who are newcomers (first visit to DFCI) are required to register at the central registration office (CRO). Subsequently, they continue to the check-in desk, where they are served by the clinical scheduling assistant (CASS). The CASS verifies that the patient indeed appears in the appointment book for that day and hands-out a real-time locating system (RTLS) badge that keeps track of patient whereabouts during their entire stay. Furthermore, patients receive their daily schedule with estimated start times for the various activities.
Next, depending on the patient’s purpose of visit, patients are routed to their next appoint- ment. Approximately 50% of patients arrive for a consultation, which may be due to one of several reasons: (1) second opinion after diagnosis, (2) genetic consulting, and (3) an intake prior to treatment. These patients are routed to a consulting physician and depart immediately after their consultation is over.
The other 50% of patients arrive to start or continue a series of chemotherapy treatments. We shall refer to these patients as on-treatment patients (OTP). All OTP are required to perform a blood draw at the entry. Patients check-in at the blood-draw department and receive a virtual timer that measures their wait time while they wait for their turn. When patients are waiting longer than 45 minutes, a nurse is notified. He then must find the patient and apologize for the long wait time. Waiting patients are categorized to one of two types: (1) complex patients who are served by a nurse, or (2) regular patients who are served by a phlebotomist. (Phlebotomists may only draw blood, while nurses may also provide additional care.)
When OTPs exit the blood-draw area, they continue to their next appointment, while their blood samples are sent via a designated vacuum elevator to the central lab facilities of DFCI. There, samples are processed by the lab’s staff members, and the results are inserted into the EPIC system. Patients that do not require a doctor’s examination on the day of their treatment continue directly to chemotherapy infusion, which is conditioned on their blood results (i.e., infusion may be canceled if blood results are not satisfying).
The other OTPs require a physician’s examination prior to entering chemotherapy infusion. When the provider is ready to see the patient, and the patient’s blood result is ready, the patient may enter the examination room. During the examination, the physician may decide that the patient will not receive a chemotherapy infusion, due to clinical considerations (e.g., due to non- supporting blood results). A patient for whom the infusion is canceled, leaves DFCI through a check-out with a CASS, who may schedule new appointments with the patient. If the patient

is eligible for infusion, the physician inserts the corresponding dosage and drug specifications into the EPIC system. Consequently, the infusion nurse (InfRN) is notified with the relevant instructions via an EPIC module. The patient may then continue and receive chemotherapy treatment.
Prior to infusion, the following preconditions must be fulfilled: the blood results need to be ready, the patient’s chemotherapy drug needs to be prepared, and an infusion chair must become available. Chemotherapy medications in DFCI are produced on the day of treatment (so that they are not wasted, in case a patient does not show up). The pharmacy unit receives prescriptions for all medications that patients require (via the EPIC system). These prescriptions are typed by physicians on the day of treatment. When patient’s medications (there can be more than one) are ready, they are double-checked by the pharmacy’s shift manager, and the drug is sent to the relevant medical floor by a designated elevator. Subsequently, EPIC is updated and the InfRN receives a signal to collect the drug.
Next, the InfRN collects the drug, and carries it to the infusion chair. The drug is then installed in the form of an infusion bag. The InfRN sits the patient into the infusion chair according to a schedule-based ordering protocol, and the infusion is started. Then, the InfRN presses a button on his RTLS badge, which sends an update to the EPIC, notifying it that the infusion has started. Once patients are done with chemotherapy they leave the building after a checkout procedure with a CASS.
