129,898 sepsis events
CDC Adult Sepsis Event criteriaTotal CDC Adult Sepsis Events across the selected cohort. The criteria do not require an ICU stay — sepsis is identified from infection, organ dysfunction and treatment signals wherever they occur — and one hospitalization can contribute more than one event.
about 1 in 3 hospitalizations in this cohort had at least one sepsis event — 59,819 of 179,134 (33.4%)
130,007 ICU episodesTotal number of separate ICU stays. A new episode begins when the patient passes through ward, stepdown, L&D, hospice, psych, rehab or other between two ICU rows. Lateral ICU-to-ICU transfers and trips to procedural, radiology or dialysis stay within the same episode.

ventilator hoursTotal invasive ventilation hours summed across every hospitalization in the cohort.

Median hours to extubationA patient counts as extubated when two consecutive readings on invasive ventilation are followed by two consecutive readings off it. Requiring two on each side stops a single stray reading registering as an extubation. Patients already ventilated on arrival are excluded, since their true start time is unknown.
Ventilator-free days28-day ventilator-free days. The window is ventilation start through day 27. Death inside the window scores 0; still ventilated at day 28 scores 0; never re-ventilated scores 28. Free days between a reintubation do NOT count. 0 of 28 days

Non-invasive device-free days28-day non-invasive device-free days, computed like VFD but counting time off non-invasive support (ONLY hospitalizations that received NIPPV or CPAP, or high-flow nasal cannula at 30 L/min or more) — not every hospitalization on respiratory support. 0 of 28 days

First Location at IMV StartThe ADT location the patient occupied when invasive ventilation began — where they were intubated, not where they were admitted.
Initial Ventilator ModeThe first ventilator mode charted at or after ventilation start — one per invasively ventilated hospitalization. Other pools APRV, blow by, standby, volume support and the upstream "other" category. Hospitalizations with no mode charted are excluded.

Interactive Data Explorer
Explore consortium data across 12 institutions and 16 years. Use the filters below to customize your view.
Note: To protect patient privacy, values with n < 10 are shown as "-" and excluded from export. Sub-categories may therefore not add up exactly to their parent totals — small counts are suppressed, rare categories are combined into "other" (see each row's for what it covers), and some unknown or missing categories are not displayed.
Data Coverage: Sites have varying data coverage periods. Use the Table view to see years covered for each site, then select appropriate sites and years for valid comparisons.

Hourly Trends
Explore medication and respiratory support patterns over the first 7 days of ICU admission across 12 institutions.
Note: Data shows medication administration patterns aggregated across all ICU encounters at each institution.
Time is measured from each patient's first ICU admission (hour 0 = first hour in ICU, hour 24 = end of day 1, hour 167 = end of day 7).
Data Distributions
Compare lab values, vital signs, and respiratory parameters across institutions using histograms and empirical cumulative distribution functions (ECDF).
Measurement window:
Reference units: some sites' values are under review for reference-unit mismatches, so a site's curve may sit on a different scale than its peers for a given parameter.
How to interpret the chart:
Histogram bars show frequency - what percentage of measurements fall in each value range.
ECDF lines show cumulative probability - what percentage of ALL measurements are at or below that value.
Example: If you hover at Albumin = 3.0 g/dL and see:
- Site A: 25% → 25% of Site A's albumin values are in the bin around 3.0
- Site A ECDF: 60% → 60% of Site A's albumin values are ≤ 3.0 g/dL
The ECDF tells you "how many patients have values this low or lower" while the histogram shows "how common is this specific value range."
Tip: First select a parameter from the sidebar, then choose which sites to compare. We recommend selecting 2-3 sites at a time for cleaner visualizations.

Data Source
This dashboard presents aggregated, de-identified data from the CLIF Consortium spanning 2011-2026. All data has been standardized according to CLIF data format specifications and undergoes rigorous quality assurance processes. MIMIC IV data is included for benchmarking purposes.
Methodology: Median values shown are weighted medians calculated using site-specific sample sizes. Interquartile ranges (IQR) represent the minimum Q1 to maximum Q3 observed across sites as an approximation for aggregated data.
