2.2 KPI ID2: diagnosis/intervention: timely assessment of women with hepatitis B

National performance of ID2 (see standard IDPS-S06) in quarter 1 2024 to 2025 was 69.0%. The submission of data for ID2 has changed in 2023 to 2024 from maternity service self-reporting to the Integrated Screening Outcomes Surveillance Service (ISOSS) to improve consistency and accuracy of data returns. This has led to an expected reduction in performance as a result of more accurate data, and does not reflect a change in practice for screening providers.

ID2 is a small number KPI, therefore the data should be interpreted with caution.
