An Internet-Based Patient-Provider Communication System: Randomized Controlled Trial

BACKGROUND: Internet-based interactive websites for patient communication (patient portals) may improve communication between patients and their clinics and physicians. OBJECTIVE: The aim of the study was to assess the impact of a patient portal on patients' satisfaction with access to their clinic and clinical care. Another aim was to analyze the content and volume of email messages and telephone calls from patients to their clinic. METHODS: This was a randomized controlled trial with 606 patients from an academic internal medicine practice. The intervention "portal" group used a patient portal to send secure messages directly to their physicians and to request appointments, prescription refills, and referrals. The control group received usual care. We assessed patient satisfaction at the end of the 6-month trial period and compared the content of telephone and portal communications. RESULTS: Portal group patients reported improved communication with the clinic (portal: 77/174 44% "a little better" or "a lot better;" control: 18/146 12%; chi2 = 38.8, df = 1, P < .001) and higher satisfaction with overall care (portal: 103/174 59% "very good" or "excellent;" control: 78/162 48%; chi2 = 4.1, df = 1, P = .04). Portal group patients also reported higher satisfaction with each of the portal's services. Physicians received 1 portal message per day for every 250 portal patients. Total telephone call volume was not affected. Patients were more likely to send informational and psychosocial messages by portal than by phone. Of all surveyed patients, 162/341 (48%) were willing to pay for online correspondence with their physician. Of those willing to pay, the median amount cited was 2 USD per message. CONCLUSIONS: Portal group patients demonstrated increased satisfaction with communication and overall care. Patients in the portal group particularly valued the portal's convenience, reduced communication barriers, and direct physician responses. More online messages from patients contained informational and psychosocial content compared to telephone calls, which may enhance the patient-physician relationship.
