Internal Medicine

Overview

Internal medicine physicians provide comprehensive care for adults including diagnosis, treatment and prevention of complex multisystem disease. They coordinate care across specialties and manage chronic conditions such as diabetes, hypertension and heart failure. Many internists subspecialize in areas like cardiology, gastroenterology or infectious disease.

Clinical Practice

Internists perform detailed history and physical examination, order and interpret diagnostic tests and manage inpatient and outpatient care plans. They emphasize continuity of care, preventive medicine and care coordination for multimorbidity. Hospitalists are internists who focus on inpatient management and transitions of care.

Procedures and Tools

Common tools include point of care ultrasound, bedside procedures such as paracentesis and central line placement, and use of EHR based decision support. Internists rely on laboratory and imaging data to guide complex medical decisions. Chronic disease management programs and multidisciplinary clinics support long term outcomes.

Training and Roles

Internal medicine training includes residency with opportunities for fellowship subspecialization; board certification and maintenance of competence are required. Internists often lead primary care teams, quality improvement initiatives and population health programs. They collaborate closely with specialists, nurses, pharmacists and allied health professionals.

Pediatrics

Overview

Pediatricians manage growth, development, acute illnesses and chronic pediatric conditions and provide immunizations and anticipatory guidance. They coordinate care with subspecialists for congenital, genetic and complex pediatric disorders. Pediatric care emphasizes family centered approaches and developmental surveillance.

Clinical Practice

Pediatricians perform well child visits, developmental screening and manage common childhood infections and chronic conditions such as asthma and diabetes. They collaborate with schools, social services and subspecialty teams to support child health and safety. Neonatology and pediatric critical care address the needs of the sickest infants and children.

Procedures and Tools

Common pediatric procedures include immunizations, lumbar puncture, and minor laceration repair; growth charts and developmental screening tools guide care. Pediatric dosing and equipment sizing require specialized knowledge and protocols. Child life specialists and family support services enhance the care environment.

Training and Roles

Pediatricians complete residency training in child health and may subspecialize in areas such as pediatric cardiology, gastroenterology or infectious disease. Certification and maintenance of competence include pediatric specific skills and communication with families. Pediatric nurse practitioners and physician assistants extend access to pediatric care.

Cardiology

Overview

Cardiology manages coronary disease heart failure arrhythmias and valvular disorders using imaging and invasive procedures. Preventive cardiology and risk modification are central to reducing morbidity and mortality. The specialty integrates diagnostics with interventional and device therapies.

Clinical Practice

Cardiologists use ECG echocardiography stress testing cardiac CT and MRI and invasive catheterization for diagnosis and management. Treatments include medical therapy device implantation and percutaneous interventions. Multidisciplinary heart teams coordinate complex care.

Procedures and Tools

Common procedures include cardiac catheterization percutaneous coronary intervention pacemaker and defibrillator implantation and structural interventions. Hemodynamic monitoring and advanced imaging guide decision making. Procedural safety and post procedure care are essential.

Training and Roles

Cardiologists complete internal medicine residency followed by cardiology fellowship and may subspecialize in interventional cardiology electrophysiology or heart failure. Ongoing certification and procedural volume maintain competence. Many participate in research and quality improvement.
