A set of skills and scope of practice may define a primary care physician, generally including basic diagnosis and treatment of common illnesses and medical conditions.[1] Diagnostic techniques include interviewing the patient to collect information on the present symptoms, prior medical history and other health details, followed by a physical examination. Many PCPs are trained in basic medical testing, such as interpreting results of blood or other patient samples, electrocardiograms, or x-rays. More complex and time-intensive diagnostic procedures are usually obtained by referral to specialists, due to either special training with a technology, or increased experience and patient volume that renders a risky procedure safer for the patient.[2] After collecting data, the PCP arrives at a differential diagnosis and, with the participation of the patient, formulates a plan including (if appropriate) components of further testing, specialist referral, medication, therapy, diet or life-style changes, patient education, and follow up results of treatment.
