This source reproduces the legacy V4
nhsnsource, itself the continuation of the earlierhhshospitalization source. V5 expands coverage from raw admission counts to the complete NHSN metric suite (including bed capacity and occupancy, current inpatient and ICU census, age-stratified admissions, population-adjusted rates, and hospital reporting compliance), adds census-level aggregation, and folds the preliminary dataset into each signal’s revision history rather than publishing separate_prelimsignals. See Relationship to V4.

Overview
The National Healthcare Safety Network (NHSN) collects weekly respiratory admission, inpatient and ICU census, bed capacity, and reporting compliance metrics from acute care hospitals across the United States. Delphi ingests the weekly Hospital Respiratory Data release published by the CDC on HealthData.gov, covering COVID-19, influenza, and RSV admissions, patient census, bed occupancy, reporting coverage, and seasonal cumulative totals.
All 319 active indicators defined in the upstream CDC dataset schema are ingested and standardized into Delphi’s unified V5 schema.

Estimation
Metric Definition
Signals correspond to source fields in the upstream CDC NHSN Hospital Respiratory Data release (see the CDC Socrata dataset ua7e-t2fy). In each table above, the “CDC Field Name” column records the original column identifier (fieldName) from the CDC dataset. Metrics fall into several distinct families:
- Counts. Raw counts (e.g.,
confirmed_admissions_*_ew,*_inpatients_*_ew,inpatient_beds_*_ew,hosprep_*_ew,*_cumulative_ew). - Percentages. Ratios multiplied by 100. Identified by
_pct_in the signal name (e.g.,inpatient_beds_occupied_pct_ew,confirmed_admissions_*_pct_ew,*_inpatients_icu_pct_ew). - Rates per 100,000 Population. Confirmed new admissions normalized per 100,000 population, calculated using U.S. Census Bureau population estimates (with national rates incorporating U.S. territories). Identified by
_per100k_(e.g.,confirmed_admissions_*_per100k_ew). - Week-over-Week Percent Change. Relative percent change in weekly admissions compared to the prior week. Identified by
_chg_pct_(e.g.,confirmed_admissions_*_chg_pct_ew). - Reporting Coverage Percentages. Percentage of total active facilities in the jurisdiction submitting data for each metric. Identified by
hosprep_pct_(e.g.,hosprep_pct_*_ew). - Absolute Percentage Points Change. Week-over-week absolute change in facility reporting coverage percentage points. Identified by the prefix
abs_chg_(e.g.,abs_chg_hosprep_pct_*_ew). - Reporting Threshold Flags. Binary indicator variables taking value
1if jurisdiction hospital reporting coverage meets or exceeds the threshold (80% or 90%), and0otherwise. Identified by the prefixflag_(e.g.,flag_hosprep_*_ew).
Temporal Handling
All signals are reported weekly and labeled by the Saturday week-ending date (reference_time). The time window represented depends on the metric:
- New admissions are measured across the full 7-day surveillance week (Sunday through Saturday).
- Bed capacity, occupancy, and patient census represent single-day snapshot values captured on Wednesday of the reporting week.
The CDC publishes a preliminary weekly file about 4 days after the reference week ends (Wednesday), followed by a finalized file 2 to 3 days later (Friday or Saturday). Both releases share the same signal names and are distinguished by publication date (report_time). Default snapshot queries return the latest finalized values, while earlier preliminary releases remain accessible by specifying a past snapshot_date or through the /archive/ endpoint.
Geographic Handling
The source file carries values for states (state), HHS regions (hhs), and the nation (nation), which Delphi reads directly from the upstream CDC file.
Census divisions (census_division) and census regions (census_region) are derived from state values:
- Count metrics are summed directly across member states based on the U.S. Census Bureau regions and divisions.
- Rate and percentage metrics are aggregated using population-weighted averages based on 2020 U.S. Census state populations.
- Week-over-week percentage change signals are omitted from census division and census region roll-ups.
Values are ingested directly or aggregated without imputation, so fill_method is always source.
Relationship to V4
The V4 nhsn source published admission counts for nation, HHS regions, and state. The signal names that overlap remain the same in the V4 to V5 transition.

What changed in V5:
- New Signals. V5 expands the signal catalog from 6 basic admission counts to 319 comprehensive indicators.
- Expanded Geographies. V5 adds census divisions and census regions.
- Preliminary Data. The CDC publishes a preliminary weekly file a few days ahead of the finalized file. V4 presented the preliminary file as separate
_prelimsignals. V5 writes both files to the same signal names, so the preliminary numbers appear as an earlier release and the finalized numbers supersede them on the next update. Read a pastsnapshot_date, or use the/archive/endpoint, to recover the preliminary values.

Missingness & Privacy
The source applies no cell suppression or volume masking. All reported counts and percentages are published directly without privacy thresholds.
Unobserved values reflect facility non-reporting and changes in reporting mandates over time:
- Reference dates before December 1, 2020 predate routine data quality review procedures, such as automated exclusion of invalid values and systematic error correction. Data from this early period may contain anomalies.
- Reference dates through April 30, 2024 reflect a federal reporting mandate instituted by the Department of Health and Human Services.
- Reference dates between May 1, 2024 and October 31, 2024 fall into a voluntary reporting interval following the expiration of the original federal mandate. Facility participation dropped significantly during these months, meaning reported admissions undercount total admissions.
- Reference dates beginning November 1, 2024 reflect the current federal reporting mandate established under updated CMS conditions of participation.
Missing hospital reports are not imputed. In census division and region roll-ups, missing states are omitted from the sum.
Limitations
NHSN collects data from acute care hospitals. Psychiatric, rehabilitation, and religious non-medical facilities are excluded.
Hospital counts reflect the NHSN unique hospital identifier rather than the CMS certification number. Only facilities designated as active reporters are included.
Admissions during the voluntary reporting window from May 1, 2024 through October 31, 2024 are incomplete because many hospitals did not submit data.
RSV data collected before November 1, 2024 has low completeness. Only a small fraction of hospitals voluntarily reported RSV admissions prior to the November 2024 mandate, undercounting true admissions by an estimated two orders of magnitude. The CDC RSV-NET surveillance network offers a more reliable historical benchmark for RSV admissions during that period.
Administration of this surveillance system moved from HHS Protect to NHSN in late 2023. Comparisons across the transition indicate that COVID-19 and influenza figures are largely consistent between both systems. Notable discrepancies exist for a few states, with Georgia until 2023, Louisiana, Nevada, Puerto Rico in late 2020, and Tennessee reporting lower counts in legacy HHS Protect files than in NHSN.
These indicators reflect direct census counts from reporting hospitals rather than statistical samples. Standard errors and sample sizes do not apply.
Lag & Backfill
The CDC publishes preliminary weekly data on Wednesdays, approximately 4 days after the reference week ends. Finalized weekly files publish on Fridays or Saturdays, 6 to 7 days after the reference week ends. In V5, preliminary data is ingested first and then superseded by finalized data under the same signal name.
The CDC continuously updates data for prior weeks as facilities submit late or corrected reports. Most revisions occur within 2 months of initial release. Older data rarely changes.
Approximately 20 percent of values reported within the preceding 2 months undergo revisions. These adjustments usually occur only once or twice per observation. Revisions generally increase reported counts as late submissions arrive, with a median difference of 2 percent between initial and final values.
Large revisions occur occasionally when a facility submits bulk retrospective corrections. Revision volume also varies geographically. For example, Texas experiences more frequent revisions than most states but with small shifts, typically with a median change below 0.1 percent. Other states, including Idaho, New Hampshire, Hawaii, and North Dakota, have exhibited higher percentage volatility when revised.
