Personal health records (PHRs) and patients' access to their own clinical information through a patient portal are changing the patient-physician relationship. Historically, health care providers have been gatekeepers of patients' medical records. Now, these portals provide patients access to clinical information, electronic messaging with the clinical team, and appointment and billing information. This type of access supports patient empowerment by engaging patients in their own care. Patients desire online access to information. The health care industry, like any other, must respond to the needs of its consumers. Oncology practices face unique challenges to meeting this need because of the complex nature of medical records of patients with cancer. Health care providers worry about the consequences of patients receiving "bad news" online, thereby increasing patient anxiety. This anxiety may, in turn, increase providers' workload by creating additional calls or visits to the office. These valid concerns require careful consideration when implementing a PHR or patient portal into a practice. Providers will benefit from a clear understanding of actual compared with potential risks and benefits. Much of the concerns about the negative effect on providers' workload and the potential increase in patients' anxiety have not been borne out. On the other hand, the implementation strategy, governance structure, and end-user education are crucial components to ensuring success. Successful implementation of a PHR or patient portal affords the opportunity to improve patient satisfaction and increase efficiency in provider workflow. The possibility exists to improve patient outcomes by engaging the patient in decision making and follow through.
