How accurate is information that patients contribute to their Electronic Health Record?

Increased patient interaction with medical records and the advent of personal health records (PHRs) may increase patients' ability to contribute valid information to their Electronic Medical Record (EHR) medical record. Patient input through a secure connection, whether it be a patient portal or PHR, will integrate many aspects of a patient's health and may help lessen the information gap between patients and providers. Patient reported data should be considered a viable method of enhancing documentation but will not likely be as complete and accurate as more comprehensive data-exchange between providers.
