o Sub Part 1.4.3: Professional conduct and ethical issues in clinical practice Introduction Clinical medicine begins not with stethoscopes or investigations but with conversation. The clinical interview is the most powerful diagnostic tool available to any physician: it provides the majority of the information needed for diagnosis in most medical encounters, guides the subsequent examination, and determines the therapeutic relationship that will influence whether the patient follows advice and returns for follow-up. A physician who cannot conduct an effective clinical interview is handicapped regardless of their technical skills. The aim of this Series is to define the clinical interview and describe its components, examine the structure and content of the medical history, develop the communication skills essential for effective clinical encounters, and establish the ethical and professional framework within which clinical interviews are conducted. We shall commence by defining the clinical interview and examining its components and types. Next, we will examine the detailed structure of the medical history. Moving on, we will address the communication skills that make clinical encounters effective. Finally, we will close by examining the ethical and professional dimensions of the clinical interview. Series Learning Outcomes Upon completing this Series, you should be able to: • SLO 1.1 define the clinical interview and describe its purpose and components, • SLO 1.2 take a structured and comprehensive medical history, • SLO 1.3 apply effective verbal and non-verbal communication skills in a clinical encounter,
• SLO 1.4 describe the approach to breaking bad news and managing sensitive communication, and • SLO 1.5 explain the ethical principles of informed consent, confidentiality, and professional conduct in the clinical interview. 1.1 The Clinical Interview 1.1.1 Definition and purpose of the clinical interview The clinical interview is a structured, purposeful conversation between a clinician and a patient (and sometimes a third party such as a relative or carer) aimed at gathering the information necessary to understand the patient health problem, establish a diagnosis, and formulate a management plan. It is the first and most fundamental clinical skill, because without accurate and comprehensive information from the patient, no examination finding or investigation result can be correctly interpreted. The purposes of the clinical interview extend beyond data collection. It establishes the therapeutic relationship between doctor and patient, creating the trust that underpins the patient willingness to disclose sensitive information and adhere to treatment. It identifies the patient agenda (the concerns, expectations, and ideas that the patient brings to the consultation, which may differ substantially from the presenting complaint). It also serves an educational function, providing the patient with information and explanation, and a therapeutic function, since the experience of being heard and understood has direct psychological benefit. Fill in the blank: The clinical interview serves multiple purposes including data collection, establishing the therapeutic __________ , identifying the patient agenda, providing education, and offering therapeutic benefit through being heard. 1.1.2 Components of the clinical interview
The clinical interview has two broad components: the history-taking component (the systematic collection of medical information through structured questioning, examined in detail in Part 1.2) and the communication component (the interpersonal process through which this information is exchanged, examined in Part 1.3). These two components are inseparable in practice: even the most thorough history-taking framework produces incomplete or inaccurate information if the communication process fails to put the patient at ease, fails to ask questions in a manner the patient understands, or fails to probe appropriately when initial answers are vague. The structural components of the clinical interview include: opening (establishing rapport, clarifying the reason for the visit, and setting the agenda for the consultation); information gathering (systematic history-taking using open and closed questioning techniques); physical examination (which follows and is guided by the history); explanation and planning (sharing the clinician assessment and negotiating a management plan with the patient); and closure (summarising, checking understanding, and arranging follow-up). This structure is often described as the Calgary-Cambridge framework for the medical consultation. Fill in the blank: The Calgary-Cambridge framework for the medical consultation describes five structural components: opening, information gathering, physical examination, explanation and planning, and __________ . 1.1.3 Types of clinical interview Clinical interviews vary in purpose and structure. The new patient or initial consultation is the most comprehensive, involving a full history, examination, and plan for a patient presenting for the first time. The follow-up consultation reviews progress, assesses response to treatment, and adjusts the management plan. The focused or problem-specific consultation addresses a single defined issue, typically in a patient known to the clinician, and does not require a full history from the beginning. The emergency consultation is abbreviated and directed, prioritising immediate life threats over comprehensive history. Special types include the third-party interview (conducted with a relative, carer, or interpreter when the patient cannot provide history due to altered consciousness, cognitive impairment, age, or language barrier), the paediatric consultation (which adapts questioning and communication
to the developmental stage of the child while also engaging the parent or guardian), and the psychiatric interview (which explores mental state, thoughts, perceptions, and feelings in addition to the standard medical history). Recognising which type of interview is appropriate for the specific clinical context is itself an important clinical skill. Fill in the blank: The __________ consultation is abbreviated and directed, prioritising immediate life threats over comprehensive history-taking when a patient presents in an acute or emergency situation. Figure 1.1: Components and types of the clinical interview Pilot questions 1.1 1. Define the clinical interview. 2. Name five purposes of the clinical interview beyond data collection. 3. Name the five structural components of the Calgary-Cambridge consultation framework.
4. Distinguish between a new patient consultation and a follow-up consultation. 5. When would a third-party interview be required? 1.2 The Medical History 1.2.1 Chief complaint and history of presenting illness The chief complaint (CC) is the primary symptom or problem that brings the patient to seek medical attention, recorded in the patient own words and as brief as possible (for example, "chest pain for two hours" or "difficulty breathing since yesterday evening"). The chief complaint anchors the consultation and directs the remainder of the history. It should be identified at the outset and confirmed with the patient, since the presenting complaint as documented in a referral letter or appointment record may differ from what the patient most wants to discuss. The history of presenting illness (HPI) is the detailed chronological account of the development of the chief complaint from its onset to the present. The HPI should address: onset (when and how suddenly the symptom began), duration (how long it has been present), character (quality and nature of the symptom), severity (intensity on a scale, functional impact), location and radiation (for pain), associated symptoms (other symptoms occurring concurrently), modifying factors (what makes it better or worse), and previous similar episodes. The mnemonic SOCRATES (Site, Onset, Character, Radiation, Associations, Time course, Exacerbating and relieving factors, Severity) is a commonly used framework for characterising pain. Fill in the blank: The mnemonic __________ (Site, Onset, Character, Radiation, Associations, Time course, Exacerbating/relieving factors, Severity) is used to systematically characterise a patient pain in the history of presenting illness. 1.2.2 Past medical, family, and social history
The past medical history (PMH) documents all previous significant illnesses, hospitalisations, surgical procedures, and medical conditions, including childhood illnesses, chronic diseases (diabetes, hypertension, asthma, HIV), and any known complications or sequelae. It provides the clinical context within which the presenting illness must be understood: a patient with known ischaemic heart disease presenting with chest pain carries a very different prior probability than a 20-year-old with no cardiac history. Past obstetric history is recorded separately for female patients of reproductive age. The family history (FH) documents significant illnesses in first-degree relatives (parents, siblings, children), particularly conditions with known hereditary components such as ischaemic heart disease, diabetes, hypertension, cancers, and inherited disorders. The social history (SH) documents the patient occupation, living situation, marital and family status, smoking and alcohol use, recreational drug use, dietary habits, exercise, recent travel, and any relevant social stressors. The social history is often the most neglected component of the history despite its
