Patient interview

Significance of the classical method in modern clinical practice

Despite the colossal leap in the development of instrumental and laboratory technologies, the classical bedside examination has not lost its fundamental role. Outstanding clinicians of the past, such as E.M. Tareev and Sir W. Osler, emphasized that skilled interviewing and physical examination methods are what trigger the process of continuous clinical thinking. Osler placed special emphasis on the need to constantly train a physician's senses — sight, hearing, and touch.

Novice specialists are strongly discouraged from neglecting traditional approaches in favor of rapid but narrow specialization (for example, limiting themselves exclusively to ultrasound diagnostics). Only a comprehensive mastery of all classical examination skills creates a well-rounded physician and builds a solid foundation for professional growth.

Structure and rules of taking a medical history

The communication process is built on a strict logical scheme, the foundations of which entered medical practice back in the days of G.A. Zakharyin. The physician invariably determines environmental conditions, occupational hazards, lifestyle, domestic habits (including addiction to coffee or tea), and the level of physical activity.

The standard structure of the conversation includes:

1. General patient data: full name, exact age, occupation, and workplace. Special attention is paid to ethnicity, which raises awareness regarding endemic or genetically determined pathologies.
2. Main sections: gathering complaints, history of the present illness (anamnesis morbi), and personal history (anamnesis vitae).

The conversation is cyclical in nature: the interview must be revisited multiple times as new data becomes available. Concurrently, the clinician must assess the person's mental adequacy, memory status, and ability to logically build a chronology of events, as not everyone is able to accurately describe their sensations.

Five key goals of the interview

Information gathering during the dialogue addresses several fundamental tasks:

• Diagnostic — searching for specific facts necessary to make an accurate diagnosis.
• Prognostic — preliminary assessment of the expected severity of the disease course.
• Exploratory — determining additional sources of information (interviewing relatives, colleagues of the patient, reviewing medical documentation from other specialists).
• Deontological — building a trusting relationship (compliance) between the physician and the patient.
• Psychological — studying the patient's personality, their reaction to suffering, and the formation of the so-called "inner picture of the disease".

Working with complaints: from open conversation to detailing

The conversation always starts with open-ended questions: "What is bothering you?", "What brought you to the clinic?". At the initial stage, it is critically important to let the patient speak freely without interrupting them.

Since people often omit important symptoms due to habituation (for example, a patient with hypertension may not feel chronically high blood pressure) or inattention to themselves, the physician proceeds to active questioning. Complaints are divided into:

• Primary (main) — subjectively the most significant for the person. A detailed analysis of these very complaints most often provides the key to the diagnosis, although sometimes they merely reflect the emotional background.
• Additional — identified in a targeted manner during active questioning.

Each identified symptom requires deep detailing across five parameters:

1. Localization — where exactly do the sensations occur?
2. Association — what does the patient themselves associate the onset of the problem with?
3. Background — are there any predisposing factors?
4. Dynamics — do the sensations increase, decrease, or remain stable?
5. Modifying factors — what relieves or worsens the condition?

It is also mandatory to clarify the presence of general symptoms: fever, chills, weakness, changes in weight, appetite, or thirst, and the presence of headaches. If the patient is in a state of "apparent health" and has no complaints, incidental findings during screening (hyperglycemia, radiographic changes) or changes noticed by their surroundings (e.g., skin jaundice) may serve as a reason for examination.
