Role of the Admitting Physician: Responsibilities, Workflow & Care Coordination

The admitting physician (typically a hospitalist or attending with admitting privileges) serves as the primary physician responsible for a patient's inpatient care from admission through discharge.

Core Responsibilities

1. Admission Assessment & Decision-Making

• Evaluate medical necessity for inpatient level of care (InterQual/MCG criteria)
• Perform/admit H&P within 24 hours (CMS/Joint Commission)
• Determine admission status: Inpatient vs. Observation (critical for reimbursement)
• Identify code status, advance directives, surrogate decision-makers

2. Diagnostic & Therapeutic Planning

• Order/interpret labs, imaging, diagnostics
• Formulate differential diagnosis, working diagnosis
• Initiate evidence-based treatment plan
• Anticipate complications, arrange monitoring

3. Initial Orders & Protocols

• Admission order set (vitals, nursing, activity, diet, DVT prophylaxis, glucose monitoring)
• Medication reconciliation (admission, transfer, discharge)
• Condition-specific pathways (sepsis, STEMI, stroke, COPD, heart failure)

4. Daily Management & Clinical Oversight

• Daily rounds: interval history, exam, data review, plan adjustment
• Multidisciplinary coordination: nursing, pharmacy, case management, therapy, consulting services
• Clinical deterioration recognition: rapid response, ICU transfer criteria
• Procedure coordination: consent, pre-op, post-op management

5. Communication & Education

• Patient/family updates: diagnosis, plan, expectations, goals of care
• Outpatient PCP/specialist communication: admission notification, discharge summary
• Health literacy-appropriate education: teach-back, written materials, interpreter services

6. Discharge Planning & Transition

• Early discharge planning (admission +1 day): anticipated date, barriers, resources
• Discharge criteria met: clinical stability, oral intake, ambulation, outpatient follow-up arranged
• Discharge summary: completed at discharge, transmitted to PCP <24h
• Medication reconciliation at discharge: accuracy, affordability, understanding
• Post-discharge outreach: 48-72 hr phone call, transition clinic

Admitting Models

• Hospitalist Model (Dominant): Dedicated inpatient physicians; shift-based; 15-18 patient census
• Primary Care Admission: PCP admits own patients (declining)
• Specialty Admission: Surgery, OB, oncology, cardiology admit to own services
• Co-Management: Hospitalist + consulting specialist (e.g., ortho-hospitalist)

Quality & Performance Metrics

• Length of stay (observed/expected)
• 30-day readmission rate
• Patient experience (HCAHPS)
• Mortality indices (risk-adjusted)
• Core measure compliance (sepsis, VTE, stroke, AMI)
• Documentation completeness (CDI)

The admitting physician is the quarterback of inpatient care—orchestrating diagnostics, therapeutics, consultations, and transitions to ensure safe, effective, patient-centered hospitalization.
