Objective data includes measurable and observable criteria that are specific to a clinical problem. Objective indicators are factual that can be observed. These types of data are obtained through the assessment process using the techniques inspection, palpation, percussion, and auscultation when examining the patient. Objective data is also referred to as “signs”. In medicine, a symptom is generally subjective while a sign is objective.
Subjective data is information provided by the patient or significant knowledgeable other. Objective data is information a healthcare provider obtains directly through observation or measurement, from patient records, or from diagnostic studies.
I will address What are Symptoms? What are Signs? is subsequent posts. Stay tuned.

Does your electronic medical record have a place where you can enter the “details” of your objective data? Or is it in general terms like, within normal limits, within expected range? The extent of your vulnerability may come down to the “details”. Take time to record completely your patient care.
