An automated system for insuring monitoring of myelosuppression in patients receiving self-administered oral chemotherapy.

296 Background: Protracted outpatient oral chemotherapy regimens have created new challenges for monitoring patients for toxicity. Unlike IV chemotherapy which guarantees clinician access to the patient before proceeding with therapy, oral agents can continue to be taken despite missed follow-up visits and lab draws. After observing patients return from unrecognized lapses in monitoring with severe myelosuppression, we sought to retrospectively measure risks and to prospectively test a software-based monitoring system designed to flag and notify team members of missed lab monitoring. Methods: We evaluated 117 patients who had received a standard 42-day continuous course of oral temozolomide as therapy for newly diagnosed primary malignant brain tumors to assess monitoring compliance, as well as adverse events. Standard practice is to obtain a weekly CBC with differential and platelets during the 6 weeks of concurrent chemoradiation. Grade 3 or higher hematologic events were observed in 9 (7.7%) patients. ...
