1.2 KPI FA3

1.3 KPI FA4: combined samples

FA4 (see standard FASP-SO6) was introduced in 2020 to 2021. New KPIs are not published in the first year of data collection. This time is used to improve the data quality and completeness, by revising the definition, adding clarity and / or setting thresholds as required.

In quarter 2 2024 to 2025, national performance of FA4 for inadequate combined samples was 3.5%. FA4 is a KPI where a lower performance is better.

Quarter 2 performance

1.4 KPI FA4: quadruple samples

FA4 (see standard FASP-S06) was introduced in 2020 to 2021. New KPIs are not published in the first year of data collection. This time is used to improve the data quality and completeness, by revising the definition, adding clarity and / or setting thresholds as required.

In quarter 2 2024 to 2025, national performance of FA4 for inadequate quadruple samples was 7.6%. FA4 is a KPI where a lower performance is better.

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

National performance of ID2 (see standard IDPS-S06) in quarter 2 2024 to 2025 was 64.1%. 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.

In April 2023 the acceptable threshold changed from greater than or equal to 70% to greater than or equal to 75%. Due to the way the chart is currently produced, the acceptable threshold is presented as greater than or equal to 75% for all time periods.

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