All physicians first complete medical school (MD, MBBS, or DO). To become primary care physicians, medical school graduates then undertake postgraduate training in primary care programs, such as family medicine (also called family practice or general practice in some countries), pediatrics or internal medicine. Some HMOs consider gynecologists as PCPs for the care of women, and have allowed certain subspecialists to assume PCP responsibilities for selected patient types, such as allergists caring for people with asthma and nephrologists acting as PCPs for patients on kidney dialysis. Emergency physicians are sometimes counted as primary care physicians. Emergency physicians see many primary care cases, but in contrast to family physicians, pediatricians and internists, are trained and organized to focus on episodic care, acute intervention, stabilization, and discharge or transfer or referral to definitive care, with less of a focus on chronic conditions and limited provision for continuing care. A set of skills and scope of practice may define a primary care physician, generally including basic diagnosis and non-surgical treatment of common illnesses and medical conditions. 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. 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. Primary care physicians also counsel and educate patients on safe health behaviors, self-care skills and treatment options, and provide screening tests and immunizations. A primary care physician is usually the first medical practitioner contacted by a patient, due to factors such as ease of communication, accessible location, familiarity, and increasingly issues of cost and managed care requirements. In some countries, for example Norway, residents are registered as patients of a (local) doctor, and must contact that doctor for referral to any other. Also many health maintenance organizations position PCPs as 'gatekeepers', who regulate access to more costly procedures or specialists. Ideally, the primary care physician acts on behalf of the patient to collaborate with referral specialists, coordinate the care given by varied organizations such as hospitals or rehabilitation clinics, act as a comprehensive repository for the patient's records, and provide long-term management of chronic conditions. Continuous care is particularly important for patients with medical conditions that encompass multiple organ systems and require prolonged treatment and monitoring, such as diabetes and hypertension. Studies that compare the knowledge base and quality of care provided by generalists versus specialists usually find that the specialists are more knowledgeable and provide better care. However, these studies examine the quality of care in the domain of the specialists. In addition, these studies need to account for clustering of patients and physicians. Studies of the quality of preventive health care find the opposite results
