The Keyword Effect: A Grounded Theory Study Exploring the Role of Keywords in Clinical Communication

OBJECTIVES

Keywords, also known as "buzzwords" or "trigger words," serve as memorable descriptors to associate physical findings with specific diagnoses. These terms, such as "target lesion" and "steeple sign," liken a physical or radiographic finding to a nonmedical comparator as a means to elicit an associated diagnosis. Keywords permeate medical literature and clinical conversations. However, the potential for miscommunicating critical information exists and the impact of keywords on communication-related medical error is unknown. We explored the use of keywords and how physicians perceive their use in their clinical communication as part of patient care.

METHODS

With a grounded theory approach, semistructured interviews were completed in 2016 to 2017 with a purposive sample of 15 resident and attending physicians working in one pediatric emergency department, where clinical conversations occur frequently between providers of different specialties and levels of training. Constant comparative analysis for emergent themes was conducted. We identified key themes and examined their relationships to theorize how keywords affect clinical communication.

RESULTS

We identified three major aspects: 1) keywords belong to the culture of medicine, by which providers connect with each other using specialized terms that imply a shared experience and knowledge base. This culture encourages keyword use. 2) By encapsulating a pattern of clinical findings into one word or short phrases, keywords allow for convenient, efficient communication of both diagnoses and of thought processes between providers. 3) Keywords, however, may mislead; if incorrectly applied to a given clinical situation, they may be misinterpreted by the receiver, or they may introduce bias to diagnostic decision making.

CONCLUSIONS

More than simple descriptors, keywords can communicate entire diagnoses and activate illness scripts between providers. Also, keywords are integral to the culture and language of medicine. However, providers should be aware of the potential negative effects of keywords in clinical conversations and must balance the demands of efficient and accurate communication with the potential for miscommunication and error.

Why Is Treatment Urgency Often Overestimated? An Experimental Study on the Phenomenon of Over-triage

In the 19th century, triage emerged as an administrative concept to overcome the unjust and medically unreasonable consequences of an unsystematic adhoc selection of casualties. Until today, however, triage concepts are often applied incorrectly. High over-triage rates are a well-known phenomenon, which increase mortality rates. In order to examine their frequent occurrences, the article discusses different reasons and presents results of an experimental study. Two triage exercises were conducted: a paper-based triage exercise and a real-world simulation. Both exercises used the same case-vignettes consisting of 5 pairs. Each pair described a patient with the same injury pattern and vital parameters but with differing behaviour (calm/highly excited). Different behavior has a minor but no significant effect on over-triage rates. Over-triage is significantly higher in the real-world simulation than in the paper exercise. This is explained by the characteristics of face-to-face situations themselves: they are more complex and ambiguous, and hold more normative power. Accordingly, over-triage is understood as a means to resolve unclear situations ("better to over- than to under-triage") and to comply with normative demands "within" the strict margins of an administrative concept.
