Secure Text Messaging in Healthcare: Latent Threats and Opportunities to Improve Patient Safety

Text Messaging Inappropriately Replaces Critical Communications that Should Happen in Person or by Phone

Text messaging has de-emphasized interpersonal communication skills and behaviors critical for quality and safety in hospital-based care. This concern emerges alongside evidence suggesting that new generations of physician trainees have profoundly different communication habits, preferences, and skillsets based on their experience in a text-heavy, asynchronous world of communication.¹² There is reason to worry that reliance on text messaging in healthcare leads to similar alterations in relationships and collaboration as it has in our broader cultural context.¹³ Academic medical centers in particular should attempt to mitigate the loss of profound and formative learning that occurs during face-to-face encounters between providers of different disciplines, experience levels, and specialties.

Text Messaging Increases the Risk of Communication Error

Finally, text messaging appears to be highly vulnerable to communication errors in the healthcare setting. Prior work emphasizes the importance of nonverbal communication in face-to-face and even voice-to-voice interactions, highlighting the loss of fidelity when using text-only methods to communicate.¹ Furthermore, the asynchronous nature of text messaging grants little room for clarification of minor misunderstandings that often arise in text-only communication through minor alterations in punctuation or automatic spelling corrections, a frequent occurrence when using medical terminology. Although a seasoned physician may be able to piece together the issues that deserve further clarification, young residents may be more hesitant to ask clarifying questions and determine the right course of action due to clinical inexperience.

Deliberate Design and Implementation

A recent systematic review identified a lack of high-quality evidence evaluating the impact of mobile technologies on communication and teamwork in hospital settings.¹⁴ This paucity of understanding renders communication via STMS in the healthcare setting uniquely vulnerable to latent safety threats unless the design and implementation of these systems are purposeful and proactive.

These concerns led us to postulate that deliberate and proactive implementation of these systems, rather than passive adoption, is needed in the healthcare environment. We propose a number of approaches and interventions that may guide institutions as they seek to implement STMS or redesign communication in the inpatient setting. At the core of these proposals lies an important tension: can implementation of STMS occur in isolation or should the arrival of these systems prompt an overhaul of an institution’s clinical communication system and culture?¹⁵

Proactive Surveillance

Surveillance is one proactive method for healthcare systems to understand where and how the implementation of STMS might lead to safety threats. From a quantitative standpoint, understanding the burden of messaging for each user across the system can reveal the clinical roles in the system that are particularly vulnerable to alert fatigue or information overload. Quality assurance monitoring of critical roles in the hospital (ie, airway emergency team, rapid response teams) could be conducted to ensure accurate directory listings at all times. Associating conversations with events, from serious safety events to near misses, could help leaders understand when and how text messaging contributes to safety events and create actionable learnings for safety learning systems.
