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, some providers were justifiably unable 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 in Q4 2020 to 2021 was 99.2%, the same as 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 2017.
All screening services that submitted data (138 out of 143) met the acceptable threshold of 90%, with 135 meeting the achievable threshold of 95% and 26 of them reporting performance of 100%.

In Q4, 139 out of 143 screening services submitted data.
1.3 KPI FA4: combined samples
FA4 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 Q1 2021 to 2022, national performance of FA4 for inadequate combined samples was 3.4%. FA4 is a KPI where a lower performance is better.
Of the 143 screening services, combined sample data was reported for 140 of them through data returns from 20 of the 22 FASP laboratories.

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.
141 out of 143 screening services submitted data for this KPI for Q1.

4.2 KPI NB2: test – quality of the blood spot sample
National performance of NB2 in Q1 was 2.3%, the same as 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.
All 143 screening services submitted data, 60 met the acceptable threshold and 20 met the achievable threshold of 1%.

5.1 KPI NH1: coverage
National performance of NH1 in Q1 was 98.7%, slightly higher than the previous quarter. The trend graph below shows that England NH1 performance has met the acceptable threshold of 98% for the second time since Q4 2019 to 2020.
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 in Q1 was 90.0%, lower than the previous quarter but still meeting the acceptable threshold of 90%. 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 to above the acceptable threshold.
During the COVID-19 pandemic in line with NHSE guidance, many audiology departments closed. This resulted in a delay in the assessment of babies referred from the screen in most services.

6.2 KPI NP3: diagnosis/intervention – timeliness of ultrasound scan of the hips for developmental dysplasia
NP3 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. After this time, NHSEI will review the data with the aim of publishing it from the following year.
