Medical history

From WikiMD's Wellnesspedia

Medical history, also referred to as case history or anamnesis (from the Greek: ἀνά, aná, meaning "open", and μνήσις, mnesis, meaning "memory"), is a systematic collection of information about a patient's past and present health. It provides invaluable data for physicians and other health professionals to understand, diagnose, and treat ailments.

Introduction[edit | edit source]

The process of gathering a medical history revolves around physicians seeking answers to specific questions. These questions can be directed towards the patient or people acquainted with the patient, such as family members or caregivers. The ultimate goal is to accumulate data that assists in formulating a precise diagnosis and in devising an appropriate care plan for the patient.

While patients report their issues, which are known as symptoms, health professionals discern clinical signs through direct examination. Virtually all healthcare encounters involve the recording of a medical history. However, the depth and breadth of these histories can vary widely based on context and the specific medical professional involved. For instance, an ambulance paramedic would focus on the most critical information, like the patient's name and immediate symptoms, whereas a psychiatric history could delve deeply into numerous aspects of a patient's life.

The Importance of Medical History[edit | edit source]

The data derived from this historical account, combined with a physical examination, empowers physicians and other health professionals to make an accurate diagnosis and establish a treatment plan. When a clear diagnosis isn’t immediately evident, a provisional diagnosis becomes the starting point. From here, multiple potential diagnoses, known as differential diagnoses, are outlined, conventionally ordered from most to least likely. Depending on the situation, further tests might be needed to clarify the diagnosis.

Furthermore, the history and physical examination (often abbreviated as H&P) is a standardized procedure wherein medical professionals gather past and current health data to make informed clinical decisions. A clinician's expertise in posing the right questions is essential to deriving insights from the patient's responses. This structured approach generally begins with understanding the primary reason for the patient's visit, followed by a thorough investigation of their medical past and an exhaustive review of symptoms spanning various body systems. Subsequent to the comprehensive history assessment, a pertinent physical exam is conducted. Decisions regarding further tests and treatments hinge on the insights derived from the H&P.

Example

Conducting a medical history involves understanding various facets of a patient's health and life:

  • Identification and Demographics: This includes name, age, height, and weight.
  • Chief complaint (CC): Pinpointing the primary health concern and its duration, like chest pain persisting for the past 4 hours.
  • History of the present illness (HPI): Elaborating on the issues presented in the CC.
  • Past medical history (PMH): This encompasses major ailments, surgeries, ongoing conditions, and so forth.
  • Review of systems (ROS): A systematic probe into symptoms across different organ systems.
  • Family diseases: Particularly those relevant to the main health concern.
  • Childhood diseases: Especially vital in pediatric contexts.
  • Social history (medicine): Delves into the patient's living conditions, occupation, marital status, drug use, travel history, etc.
  • Medication Record: Captures both prescribed medicines and over-the-counter or alternative medicine choices.
  • Allergies: Notes sensitivities to medicines, foods, and environmental factors.
  • Sexual and Reproductive History: Includes sexual behaviors, obstetric/gynecological history, and related topics.

To conclude the medical history-taking process, healthcare professionals either adopt comprehensive history taking, where they ask a predetermined, extensive set of questions, or iterative hypothesis testing, wherein questions are adaptive and tailored based on prior information. The advent of technology has also ushered in computerized history-taking, potentially integrated within clinical decision support systems.

The medical journey doesn't end once the initial history is taken. A continuation process or follow-up, often termed as catamnesis in the medical domain, is set in motion to track the progress and outcomes of treatments or interventions.
