Physician's interviewing styles and medical information obtained from patients

Area of Science:

• Medical Communication
• Physician-Patient Interaction
• Clinical Information Gathering

Background:

• Effective communication is vital for accurate medical diagnosis.
• Physician interviewing techniques significantly influence the quality of patient information obtained.
• Understanding factors affecting information elicitation is key to improving patient care.

Purpose of the Study:

• To examine the relationship between physicians' interviewing styles and the amount of medical information gathered.
• To identify specific communication strategies that enhance patient disclosure.
• To assess the impact of physician expertise on information elicitation.

Main Methods:

• Analysis of audiotapes and transcripts from simulated patient encounters with 43 primary care practitioners.
• Content analysis of transcripts to evaluate physician communication processes and information content.
• Scoring of physician proficiency and patient disclosure using expert-generated criteria.

Main Results:

• Physicians elicited only slightly over 50% of expert-recommended medical information.
• Both open and closed questions correlated with patient disclosure, with open questions showing a stronger association (r=0.72).
• Patient education (prognosis, cause, prevention) and physician interviewing styles were significantly related to information disclosure, whereas clinical expertise showed a weak association (r=0.16).

Conclusions:

• Physician interviewing styles, particularly the use of open-ended questions, are critical for maximizing patient information disclosure.
• Enhancing patient education during consultations can improve the completeness of medical information gathered.
• Strategies focusing on communication skills and patient education may be more effective than relying solely on clinical expertise to improve information gathering.
