Hospital medicine

Hospital medicine is the discipline concerned with the general medical care of hospitalized patients. Doctors whose primary professional focus is hospital medicine are called hospitalists. Their activities may include patient care, teaching, research, and leadership related to hospital care. Hospital medicine, like emergency medicine, is a specialty organized around a site of care (the hospital), rather than an organ (like cardiology), a disease (like oncology), or a patient’s age (like pediatrics). However, unlike medical specialists in the emergency department or critical care units, hospitalists help manage patients throughout the continuum of hospital care, often seeing patients in the ER, admitting them to inpatient wards, following them as necessary into the critical care unit, and organizing post-acute care.

About 78 percent of practicing hospitalists are trained in general internal medicine. Another 4 percent are trained in an internal medicine subspecialty, most commonly pulmonary or critical care medicine. About 3 percent of hospitalists are trained in family practice; about 8 percent are pediatricians and 2 percent are trained as med-peds. The remaining 5 percent of hospitalists are non-physician providers, usually nurse practitioners and physician assistants.

Hospital medicine constitutes a relatively new phenomenon in American medicine. Almost unheard of a generation ago, this type of practice arose from three powerful shifts in medical practice:

• Nearly all states, as well as the national residency accreditation organization (the ACGME), have established limitations on house staff duty hours, the number of hours that interns and residents can work. This effectively reduces by 10-25% the amount of inpatient coverage provided per. Many hospitalists are coming to perform the same tasks formerly performed by residents.
• Most primary care physicians are experiencing a shrinking role in hospital care. Many primary care physicians find they can generate more revenue in the the office during the hour or more they would have spent on inpatient rounds, including traveling to and from the hospital. Furthermore, the increasingly specialized care provided in the hospital makes it difficult for primary care physicians to keep abreast of developments. Finally, fewer physicians are establishing solo practices; if one physician of a large group is delegated to make hospital rounds, most of the patients have already lost their familiar contact.
• With strong pressure to decrease inpatient length of stay, coupled with the increasing severity of illness of hospitalized patients required to justify admission, hospitalists are able to provide the increasingly necessary continual on-site availability. It has become significantly more difficult for an office-based physician to effectively direct this.

Hospitalists represent one of the most rapidly growing forms of medical practice in the US. Currently a large proportion of hospitalists are recently-graduated residents, who continue familiar duties for a few years. As residency programs are encouraged to limit inpatient duty hours and provide more outpatient education, this mattern may shift. If this specialty evolves as emergency and intensive care medicine did, it will become a formal speciality with its own residencies and board certification within a decade or two. A few distinct residency and fellowship training programs are currently operating at major universities.
