Aim 2: Characterize information needs of hospital patients and assess clinicians' attitudes toward patient engagement in the hospital setting. We will analyze the questions and comments that patients record within the PHR portal application and assess the salience of patient-entered information to issues of care quality and safety. This aim will expand our previous work in taxonomy development and hazard and near-miss recognition. A survey will be administered to collect clinicians' perceptions of the barriers to and facilitators of system use. EHR documentation will be reviewed to assess whether patient-entered information was acknowledged by clinicians, and whether changes were made to the patient's plan of care as a result.
