ED Metrics

The metrics that determine your ED's operational performance

Mediflowly surfaces these in real time, not in next month's dashboard. Each metric below is calculated from your EHR data within 60 seconds of event capture.

LOS

ED Length of Stay

Time from arrival registration to discharge or inpatient admission. Tracked by acuity level (ESI 1–5) and care pathway. Mediflowly surfaces rolling median, 90th percentile, and individual outliers in real time.

National median (CMS OP-18): ~180 min

LWBS

Left Without Being Seen

Percentage of registered patients who leave before receiving physician evaluation. A leading indicator of wait-time perception and capacity pressure. Mediflowly flags rising LWBS risk by hour and flags queue length thresholds.

Target range: <2% for most regional EDs

Door-to-Bed

Triage-to-Bed Assignment Time

Time elapsed between triage completion and first bed assignment. A key driver of LWBS and overall LOS. Mediflowly tracks this in real time by triage nurse, acuity level, and time of day to surface staffing and capacity patterns.

Benchmark top quartile: <20 min

Boarding

Boarding Patient Time

Time an admitted ED patient waits for an inpatient bed after admission order. The single largest driver of ED overcrowding. Mediflowly alerts bed management at 2-hour and 4-hour boarding thresholds and surfaces the downstream bed pipeline.

Boarding >4h is a patient safety signal
Regulatory Context

CMS OP-18 Reporting Context

CMS OP-18 (Outpatient Emergency Department — Median Time from ED Arrival to ED Departure for Admitted ED Patients) is a Hospital Outpatient Quality Reporting measure that affects hospital star ratings and public reporting. Mediflowly is designed to surface the underlying patient flow data that drives your OP-18 metric — giving your operations team visibility into contributing factors before they show up in quarterly reports.

Note: Mediflowly is designed to surface data relevant to CMS OP-18 tracking. It is not a CMS-certified reporting tool and does not submit data to CMS directly. Consult your quality reporting team for official submission requirements.
