<p>A Conceptual Model of an Oncology Information System</p>

Abstract

Introduction: Oncologists are usually faced with a huge amount of diagnostic and therapeutic data in the process of cancer care. However, they do not have access to the integrated data. This research aimed to present a conceptual model of an oncology information system based on the users' requirements. Methods: This study was conducted in 2019 and composed of two phases. Initially, a questionnaire was designed, and clinical experts (n=34) were asked to identify the most important data elements and functional requirements in an oncology information system. In the second phase, conceptual, structural and behavioral diagrams of the system were drawn based on the results of the first phase. These diagrams were also reviewed and validated by five experts. Results: Most of the data elements and all functional requirements were found important by the experts. The data elements were related to different phases of cancer care including screening, prevention, diagnosis, treatment, mental care and pain relief, and end-of-life care. Then, conceptual, structural and behavioral diagrams of the system were designed and approved by the experts or revised based on their comments. Conclusion: The conceptual model and the diagrams presented in the current study can be used for developing an oncology information system. This system will be able to manage patients' cancer data from screening to the end-of-life care. However, the system needs to be designed and implemented in a real healthcare setting to see how it can meet users' requirements.

“…In this regard, Sicotte et al [ 19 ] has shown that recording patient data and using electronic medical records led to improved flow of information, increased quality of care, and reduced the average waiting time in cancer outpatient centers. In addition, Yazdanian et al [ 20 ] stated it is possible to record patients’ clinical data electronically and manage the course of cancer from screening and prevention to treatment and beyond, despite the breadth of data elements related to cancer patient care. Levy et al [ 21 ] also created a form to collect data related to the chemotherapy protocol, assess pretreatment symptoms and provide chemotherapy training in the electronic health record.…”
