California Newborn Screening Disorder Counts 2009-2019

Aggregated data from 2009-2019 presents counts of newborn screening disorders diagnosed by the California Newborn Screening Program. The dataset includes three tables with statewide, race/ethnicity, and regional breakdowns, covering 33 core disorders from the Recommended Uniform Screening Panel. Counts are suppressed for disorders with fewer than 6 cases.

Use Cases

• Analyze statewide disorder counts to identify trends in the prevalence of core RUSP conditions over the 2009-2019 period.
• Compare disorder counts by race/ethnicity to investigate potential demographic disparities in newborn screening outcomes.
• Examine counts by California region to assess geographic variations in the diagnosis of conditions like Sickle Cell Disease.
• Track the reporting of specific disorders like SCID, ALD, Pompe, and MPS I from their respective program start dates.

Strengths

• Covers 11 years of newborn screening data from 2009 to 2019.
• Includes data on 33 core disorders from the federally recommended uniform screening panel.
• Provides breakdowns across three analytical dimensions: statewide, race/ethnicity, and region.

Limitations

• Counts are suppressed for disorders with fewer than 6 cases, limiting analysis of rare conditions.
• Data is archived and does not include screenings for Spinal Muscular Atrophy, which began in June 2020.
• The description cautions that screen-positive results do not have a one-to-one relationship with final diagnoses.
