In medical English, ‘has’ appears frequently, often in ways that require careful understanding. It’s crucial to differentiate its usage as a verb indicating possession, a part of the present perfect tense, and, indirectly, its role in scales like HAS-BLED.

‘Has’ as Possession and the Present Perfect
‘Has’ signifies possession when used with singular, third-person subjects (he, she, it). For example, “The patient has a fever.” It also forms the present perfect tense, indicating actions completed at an unspecified time in the past with relevance to the present. “The patient has been treated with antibiotics.”
‘Has Been’ vs. ‘Has Gone’
The distinction between “has been” and “has gone” is important. “Has been” implies the subject visited a place and returned. “He has been to the clinic.” “Has gone” means the subject is still there. “He has gone to the operating room.”
‘Has Been Done’ vs. ‘Has Done’
“Has been done” is passive voice, indicating something was performed on a subject. “The procedure has been done.” “Has done” is active, showing the subject performed the action. “The surgeon has done the procedure.”
HAS-BLED Score
The HAS-BLED score assesses bleeding risk in patients with atrial fibrillation. It uses clinical factors to estimate the likelihood of bleeding.
‘Has’ in Medical History Taking
When taking a patient’s medical history, ‘has’ is indispensable. Questions like “Has the patient experienced chest pain?” or “Has there been any family history of heart disease?” are standard. The present perfect tense allows for capturing information about past events that are still relevant to the current clinical picture. A negative form, often constructed using “does not have” or “has not,” is equally important. For instance, “The patient does not have any known allergies.” or “The patient has not been vaccinated against influenza this year.”
‘Has’ and Medical Devices
In the context of medical devices, ‘has’ can describe features or functionalities. For example, “This defibrillator has automatic external defibrillation (AED) capabilities.” or “The new MRI machine has improved image resolution.” These statements highlight the device’s capabilities at the present time.
‘Has’ in Research and Publications
Medical research often relies on ‘has’ to describe findings and observations. “The study has shown a significant correlation between smoking and lung cancer.” or “The research has identified a new genetic marker for Alzheimer’s disease.” In publications, ‘has’ is used to summarize previous research and to present novel findings.
Common Mistakes and Clarifications
A common mistake is using ‘have’ with third-person singular subjects. Remember, it’s always ‘he/she/it has’. Another point of confusion is the appropriate use of auxiliary verbs to form negative sentences and questions. Using ‘do/does’ correctly is essential for grammatical accuracy. For example, instead of “Has he fever?”, the correct form is “Does he have a fever?”
Understanding the different uses of ‘has’ in medical English is crucial for clear communication, accurate record-keeping, and effective patient care. By mastering its nuances, healthcare professionals can avoid misunderstandings and ensure the delivery of high-quality medical services.
