Patient Safety Component Modules
Addressing NHSN data quality issues is integral to NHSN’s ability to help facilities collect the data needed to identify areas needing prevention efforts, measure progress of prevention efforts, monitoring antibiotic use and resistance, and push toward healthcare-associated infection elimination. The NHSN Team routinely reviews the data reported to NHSN and will contact facilities to resolve confirmed and suspected data quality flags.
The NHSN team performs routine and ad-hoc data quality analysis and conducts outreach with facilities where needed, and as frequent as monthly per HAI. Our direct data quality outreach is not intended to replace internal and external data quality checks performed by the facility, state health department, or CMS.
Data quality quick tips and updates will also be presented in the NHSN Quarterly Newsletters, under ‘NHSN Data Quality Corner’.
MDRO protocol requires FacWideIN location to be included on monthly reporting plans for MRSA and CDI reporting.
Outreach is conducted for procedures reported with BMI outlier. A procedure is considered as having BMI outlier, if the following is true: procedures are reported with any of the following:
- Procedures in adults 18 years and older with BMI of less than 12 kg/m2 or greater than 60 kg/m2
- Procedures in pediatric patients (under 18 years) with BMI of less than 10.49 kg/m2 or greater than 65.79 kg/m2 (following confirmation of biological plausibility)
Confirmation of data entry for survey variables used for risk-adjustment in the SIR calculation. Facilities with significant differences in reporting from the prior year will be contacted.
Routine checks for the following: date of event before date of admission, event date is less than 3 days of the date of mechanical ventilation, date of mechanical ventilation is before date of birth, date of mechanical ventilation after the event date.
Outreach is conducted for procedures reported with procedure duration outliers. A procedure duration is considered an outlier if the duration is less than 5 minutes or greater than the interquartile range (IQR5) value for the procedure category. The IQR5 is listed in the OPC SSI section of the SIR Guide.
