What the SIR means
Many hospital infection measures use a standardized infection ratio, often called an SIR. An SIR compares observed infections with the number predicted after risk adjustment. A value above one means more infections were observed than predicted, while a value below one means fewer were observed than predicted. The comparison flag in this NYSDOH dataset identifies whether a reported measure was significantly higher, lower, or not significantly different than the NYS 2023 average.

What this can and cannot show
A higher infection flag is a warning signal in public health reporting, not proof that a hospital committed malpractice in any individual case. Hospitals differ in patient mix, services, and reporting volume, and many measures are not compared when denominators are too small. The cleanest reading is comparative and cautious. It identifies where reported infection measures were elevated, not why a specific patient was harmed.

Methodology
Figures come from the NYSDOH Hospital-Acquired Infections Beginning 2008 dataset for calendar year 2023, the most recent full year in the public file reviewed for this report. County is assigned from each hospital geocode using the plugin county GeoJSON. Rows are counted as comparable when the comparison result begins with significantly or not significantly. A worse measure is a row where the comparison result is Significantly higher than NYS 2023 average. County map values divide worse measures by comparable measures. Hospital table counts use the same rule at the facility level. Rows without usable geocodes are excluded from county and hospital rankings. This report uses aggregate public reporting and does not assess medical causation, standard of care, or any individual patient outcome.
