Yet, major problems impede communications including the frequent use of interruptive and one-way communication paradigms. This is especially frustrating for frontline providers given the dynamic nature of hospital care teams in an environment that is in constant flux.<\/jats:p><jats:p>We conducted a pre-post evaluation of a commercially available secured messaging mobile application on 4 hospital units at a single institution for over one year. We included care providers on these units: residents, hospitalists, fellows, nurses, social workers, and pharmacists. Utilization metrics and survey responses on clinician perceptions were collected and analyzed using descriptive statistics, the Kruskal-Wallis test, and Mann-Whitney U test where appropriate.<\/jats:p><jats:p>Between May 2013 and June 2014, 1,021 providers sent a total of 708,456 messages. About 85.5% of total threads were between two providers and the remaining were group messages. Residents and social workers\/clinical resource coordinators were the largest per person users of this communication system, sending 9 (IQR 2\u201320) and 9 (IQR 2\u201322) messages per person per day, and receiving 18 (IQR 5\u201336) and 14 (IQR 5\u201329) messages per person per day, respectively (p=0.0001). More than half of the messages received by hospitalists, residents, and nurses were read within a minute. Communicating using secured messaging was found to be statistically significantly less disruptive to workflow by both nursing and physician survey respondents (p&lt;0.001 for each comparison).<\/jats:p><jats:p>Routine adoption of secured messaging improved perceived efficiency among providers on 4 hospital units. Our study suggests that a mobile application can improve communication and workflow efficiency among providers in a hospital. New technology has the potential to improve communication among care providers in hospitals.<\/jats:p><jats:p>Citation: Patel N, Siegler JE, Stromberg N, Ravitz N, Hanson CW.
