Internists are physicians who specialize in adult medicine and manage a broad spectrum of acute and chronic illnesses. Hospitalists are physicians who care for patients who have been admitted to the hospital, and most are trained in internal medicine; some hospitalists come from family medicine or subspecialties. In general, hospitalists focus on inpatient care, while outpatient care and long-term management are commonly conducted by a patient’s primary care physician or consulting specialists after discharge.

Hospital medicine developed in the United States during the 1990s to meet the growing demand for efficient inpatient care and improved bed turnover. Today, hospital-based internal medicine teams are common in many countries, though the exact models and training pathways vary. Hospitalists may work in academic medical centers, community hospitals, or integrated health systems and may employ nocturnists to provide 24-hour inpatient coverage.

Key roles and responsibilities include admission evaluations, daily inpatient rounds, medication management, coordination with subspecialists, and discharge planning. Hospitalists emphasize care transitions, patient safety, and quality improvement. They often participate in hospital committees, develop protocols, and collaborate with nurses, case managers, pharmacists, and information technology staff to optimize care delivery.

Evidence on outcomes shows potential benefits from hospitalist models, such as shorter average lengths of stay and improved bed availability, along with cost containment and consistent inpatient coverage. However, concerns about continuity of care and the impact on resident education or primary care relationships have been raised, underscoring the importance of effective handoffs and clear communication.

As health systems evolve, hospitalists and internists increasingly emphasize team-based care, data-driven practice, and seamless transitions between inpatient and outpatient settings, with ongoing adaptation to electronic health records and telemedicine tools.
