General Survey and Measurement

Overview of the General Survey

  • Definition: The general survey is an overarching, systematic assessment of the whole person that begins at the very first moment of clinical encounter.

  • Core Domains of Assessment:

    • Physical Appearance: Evaluation of visual attributes including age, sex, level of consciousness, skin color, facial features, and overall appearance.

    • Body Structure: Evaluation of anatomical build including stature, nutritional status, symmetry, posture, position, and body build or contour.

    • Mobility: Observation of gait, range of motion, and physical movement.

    • Behavior: Observation of facial expression, mood, affect, speech, dress, and personal hygiene.

Physical Appearance Assessment

  • Age: Evaluation of whether the person appears their stated age or visually appears older or younger.

  • Sex: Assessment of sexual development appropriate for age and stated gender.

  • Level of Consciousness: Assessment of alertness, orientation to person, place, time, and situation, as well as responsiveness to external stimuli.

  • Skin Color: Observation of skin tone evenness, pigmentation, cyanosis, jaundice, pallor, erythema, or visible lesions.

  • Facial Features: Inspection of facial symmetry, features at rest, and facial movement during speech or expression.

  • Overall Appearance: Global evaluation for acute distress, wellness, or signs of acute or chronic illness.

Body Structure Assessment

  • Stature: Height within normal age and developmental limits.

  • Nutrition: Evaluation of weight within normal range for height and body frame, including fat distribution.

  • Symmetry: Bilateral comparison of body parts for equal size, proportion, and position.

  • Posture: Observation of standing or sitting alignment and spinal curvature.

  • Position: Observation of how the person positions themselves naturally and comfortably (e.g., sitting comfortably vs. tripoiding or lying rigid).

  • Body Build and Contour: Assessment of physical proportions and proportions of limbs to trunk.

Anthropometric Measurements

  • Weight Assessment Protocol:

    • Preparation: Direct the individual to remove shoes and heavy outer garments (such as coats or jackets) prior to stepping onto the balance scale.

    • Serial Weight Monitoring: When taking sequential weight measurements over time, obtain measurements at approximately the same time of day each time and with the individual wearing identical or similar clothing.

    • Documentation: Record measured weight values in both kilograms (kg\text{kg}) and pounds (lb\text{lb}).

  • Height Assessment Protocol:

    • Equipment: Utilize a wall-mounted measuring device or the stadiometer pole attached to a standing balance scale.

    • Technique:

    • Ensure the individual is shoeless.

    • Have the person stand straight, looking directly ahead.

    • Position the person so that heels, buttocks, shoulders, and head contact or align with the vertical plane.

    • Lower the extended horizontal headpiece until it rests flat against the crown of the head.

  • Body Mass Index (BMI):

    • Clinical Function: Serves as a practical clinical index of optimal body weight relative to height.

    • Diagnostic Utility: Acts as a reliable indicator for assessing obesity, overweight status, ideal weight maintenance, or protein-calorie malnutrition.
