Health-Care Provider Preferences for Time-Sensitive Communications from Public Health Agencies

Objective. The Rapid Emergency Alert Communication in Health (REACH) Trial was a randomized control trial to systematically compare and evaluate the effectiveness of traditional and mobile communication modalities for public health agencies to disseminate time-sensitive information to health-care providers (HCPs). We conducted a sub-study to identify the communication channels by which HCPs preferred receiving public health alerts and advisories. Methods. Enrolled HCPs were blindly randomized into four message delivery groups to receive time-sensitive public health messages by e-mail, fax, or short message service (SMS) or to a no-message control group. Follow-up interviews were conducted 5–10 days after the message. In the final interview, additional questions were asked regarding HCP preferences for receiving public health alerts and advisories. We examined the relationship between key covariates and preferred method of receiving public health alert and advisory messages. Results. Gende
