Laypeople's (Mis)Understanding of Common Medical Acronyms.

Area of Science:

• Health communication
• Medical education
• Patient safety

Background:

• Medical abbreviations are frequently used in clinical practice.
• Patient and family comprehension of these acronyms is often limited, leading to potential confusion and miscommunication.

Purpose of the Study:

• To assess the general public's understanding of commonly used medical acronyms.
• To identify factors influencing the comprehension of medical abbreviations.

Main Methods:

• A cross-sectional study surveyed 204 English-speaking adults without medical training at a state fair.
• Participants were asked to define five common medical acronyms: ED, PCP, CBC, PRN, and NPO.
• Responses were analyzed using descriptive statistics and logistic regression to identify associations with demographic factors.

Main Results:

• Understanding varied significantly by acronym, with only 32% correctly defining emergency department (ED) and 18% defining primary care provider (PCP).
• Complete blood count (CBC), as needed (PRN), and nothing by mouth (NPO) were understood by 14% and 13% of participants, respectively.
• Female gender was associated with better understanding of NPO, and older age with better understanding of PRN. Education level did not correlate with understanding.

Conclusions:

• Medical acronyms represent a significant barrier to effective patient-provider communication.
• The low comprehension rates underscore the need for clinicians to use plain language and avoid jargon when communicating with patients and their families.
• Simplifying medical terminology can enhance patient understanding and adherence to treatment plans.
