Transitions of Care, Levels of Care & Discharge

Match the unit to the patient's needs, admit as inpatient when care should cross two midnights, reconcile medications at every handoff, and plan post-acute care early.

Key numbers

Inpatient if care crosses two midnights≥ 2 midnights

SNF coverage needs 3 inpatient days3-day inpatient stay

Observation over 24 hours needs MOONMOON ≤ 36 h

IRF: 3 hours of therapy, 5 days/week3 h/day × 5 days/wk

01 · The ruleICU: ventilator, vasopressors, hourly invasive monitoring

Admit to the ICU patients who need invasive mechanical ventilation, vasopressors, ECMO, an intra-aortic balloon pump, continuous renal replacement or hourly invasive monitoring (nurse ratio 1:1 to 1:2); sepsis with life-threatening illness belongs there too.

02 · The ruleInpatient if care crosses two midnights

Medicare Two-Midnight Rule: inpatient admission is generally appropriate when the admitting practitioner expects medically necessary hospital care to cross two midnights; document the history, severity and risk that justify that expectation.

03 · The ruleSNF coverage needs 3 inpatient days

Medicare covers skilled nursing facility care only after at least 3 consecutive inpatient days (discharge day excluded); observation and ED time do not count, and the patient generally enters within 30 days.

The rules

Know these

Step-down: noninvasive ventilation, titrated drips, q2–4h checks must knowIntermediate (step-down) care fits unstable patients needing monitoring or interventions every 2–4 hours — noninvasive ventilation, IV infusions, titration of vasodilators or antiarrhythmics — at a nurse ratio of 1:3 or less.

Observation over 24 hours needs MOONObservation is outpatient care; a Medicare patient in observation over 24 hours must get the written Medicare Outpatient Observation Notice with an oral explanation no later than 36 hours after observation starts.

Telemetry ≤ 1:4; general ward ≤ 1:5Telemetry suits stable patients needing ECG monitoring for nonmalignant arrhythmias (nurse ratio ≤ 1:4); the general ward suits stable patients checked no more often than every 4 hours (≤ 1:5).

Leave the ICU when stable, not overnightTransfer a patient out of the ICU once physiology has stabilized and ICU monitoring and treatment are no longer needed; avoid after-hours (night) discharge and give a standardized oral and written handoff.

Don't wean ventilators on the general wardDo not wean mechanical ventilation on a general ward unless it is a high-dependency or intermediate unit, and do not use severity-of-illness scores alone to set or step down the level of care.

IRF: 3 hours of therapy, 5 days/weekInpatient rehabilitation fits a patient who needs multiple therapies (one being PT or OT), can tolerate about 3 hours of therapy a day at least 5 days a week, and should improve measurably.

LTACH: hospital-level care beyond 25 daysA long-term acute care hospital (average Medicare stay > 25 days) serves patients with several serious conditions who still need hospital-level care such as respiratory therapy for prolonged illness.

Home health: homebound plus face-to-face visitMedicare home health requires a homebound patient needing intermittent skilled nursing or therapy and a related face-to-face encounter within 90 days before or 30 days after the start of care; NPs may certify it.

SNF: days 1–20 covered, then coinsuranceMedicare Part A covers up to 100 SNF days per benefit period: days 1–20 fully, days 21–100 with a daily coinsurance; the patient must need daily skilled nursing or therapy.

Patients choose their post-acute providerDischarge planning must center the patient's goals and caregivers, share quality data on home health agencies, SNFs, IRFs and LTACHs, respect the patient's freedom to choose, and send necessary medical information to the next provider.

Important Message from Medicare within 2 daysGive inpatients the Important Message from Medicare (discharge appeal rights) within 2 calendar days of admission, and a follow-up copy no more than 2 calendar days before discharge.

Management

Orders

Reconcile medications at every transition must knowAt admission, transfer and discharge, take a complete medication history, compare it with the new orders and resolve every unintended discrepancy — omissions, duplications and wrong doses drive post-discharge adverse drug events.

Two-midnight exceptions: inpatient-only procedures (a list CMS began phasing out over 3 years in 2026) and shorter stays when the admitting practitioner's documented judgment supports inpatient care.

An Accountable Care Organization with an approved SNF 3-Day Rule Waiver can send a patient to a skilled nursing facility without a 3-day inpatient stay.

Pharmacist-led reconciliation prevents discrepancies, but reconciliation alone has not reduced readmissions; target it at high-risk patients — older adults, polypharmacy, anticoagulants and insulin.

SCCM suggests moving critically ill nontrauma patients from the ED to the ICU within 6 hours and using rapid response systems to find ward patients who need ICU care.

Discharge patients at high risk of death or readmission from the ICU to a step-down unit or long-term acute care hospital rather than a regular ward.

A Medicare patient changed from inpatient to observation status may appeal the denial of Part A coverage, which can restore SNF coverage.

Pearl

Observation is outpatient: those nights do not count toward the 3-day inpatient stay Medicare needs before covering a skilled nursing facility.
