Different roles in cancer care require varying levels of access to information and resources: - Oncologists: Need full access to patient medical records, treatment plans, and diagnostic results to make informed decisions about patient care. - Nurses: Require access to patient records and treatment plans but may not need access to sensitive genetic information or administrative data. - Researchers: Often require access to de-identified patient data for studies and clinical trials. - Administrative Staff: Need access to scheduling systems, billing information, and other logistical data, but not necessarily to detailed medical records.
