Antenatal and newborn screening KPI data: Q4 summary factsheets (1 January to 31 March 2023) HTML

Updated 16 January 2024

Applies to England

Please be aware that this data covers the time period through the COVID-19 pandemic. Provider performance should therefore be interpreted with caution.

In addition to this, some providers were justifiably not able to make timely data returns or validate their data in this period. We recommend looking at the historical trend data of services before the COVID-19 pandemic to help interpret the data.

This report should be read in conjunction with the full KPI data tables published each quarter.

1. Fetal anomaly screening

1.1 KPI FA2: coverage: fetal anomaly ultrasound

National performance of FA2 (see standard FASP-SO2) in Q3 2022 to 2023 was 98.8%, similar to the previous quarter. FA2 is collected 6 months (2 quarters) in arrears. The trend graph below shows that England FA2 performance has remained above the achievable threshold of 95% since 1 April 2019.

Out of all screening services who submitted data (137 out of 139) 136 met the acceptable threshold of 90%, with 132 meeting the achievable threshold of 95% and 16 of them reporting performance of 100%.

Activity for Q3 is presented by NHS regions. Coverage ranged from 98.2% in London to 99.3% in the North East and Yorkshire.

1.2 KPI FA3

There is no intention to publish FA3 (see standard FASP-S01) by individual maternity service. We are reviewing the data with the aim of publishing it nationally in the future.

In Q4 138 out of 139 screening services submitted data.

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 Q4 2022 to 2023, national performance of FA4 for inadequate combined samples was 3.7%. FA4 is a KPI where a lower performance is better.

All 21 FASP laboratories submitted data, for a total of 138 maternity services.

3.2 KPI ST2: test: timeliness of antenatal screening

National performance of ST2 (see standard SCT-S02) in Q4 was 58.3%, lower than the previous quarter. The trend graph below shows that England ST2 performance dropped below the acceptable threshold of 50% for Q1 and Q2 of 2020 to 2021 but has been back above the acceptable threshold in every quarter since then.

Data suggests that while services were maintained, performance was affected for this KPI during COVID-19 in 2020. This is not unexpected as technical guidance in place at the time stated that services could offer screening later than 10 weeks.

138 out of 139 screening services submitted data for this KPI for Q4.

4.2 KPI NB2: test: quality of the blood spot sample

National performance of NB2 (see standard NBS-S06) in Q4 was 2.4%, lower than the previous quarter. The trend graph below shows that England NB2 performance is above the acceptable threshold of 2%. NB2 is a KPI where a lower performance is better.

Due to COVID-19, during the Q1 (April to June 2020) time period newborn screening laboratories were instructed to relax blood spot acceptance criteria on samples that would normally have been rejected and to accept day 4 samples. Together these factors are likely to explain the reduced ‘avoidable repeat’ rate observed during Q1 2020 to 2021.

138 out of 139 screening services submitted data, 66 met the acceptable threshold and 25 met the achievable threshold of 1%.

5. Newborn hearing screening

5.1 KPI NH1: coverage

National performance of NH1 (see standard NHSP-S01) in Q4 was 98.9%, slightly higher than the previous quarter. The trend graph below shows that England NH1 performance has met the acceptable threshold of 98% since Q3 2020 to 2021.

During the COVID-19 pandemic in 2020 NHSP encouraged services to continue screening where safe to do so in line with national standards and the NHSP technical guidance. However, in some areas screening was delayed due to COVID-19 and we have seen lower coverage as a result. This particularly affected community services where Health Visitors suspended home visits.

5.2 KPI NH2: diagnosis/intervention – time from screening outcome to attendance at an audiological assessment appointment

National performance of NH2 (see standard NHSP-S05) in Q4 was 89.6%, higher than the previous quarter. The trend graph below shows that England NH2 performance dropped significantly in Q4 2019 to 2020 and Q1 2020 to 2021, however since then it has risen again.

During the COVID-19 pandemic in line with national guidance, many audiology departments closed. This resulted in a delay in the assessment of babies referred from the screen in most services.

NP3 (see standard NIPE-S03) was introduced in 2021 to 2022. 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 Q4 2022 to 2023, national performance of NP3 was 73.6%.

Out of 126 screening services, 10 met the acceptable threshold of 90.0%.
