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.
1. Fetal anomaly screening
1.1 KPI FA2: coverage: fetal anomaly ultrasound
National performance of FA2 in Q4 2019 to 2020 was 98.9%, slightly lower than the previous 4 quarters. FA2 is collected 6 months (2 quarters) in arrears. The national trend graph below shows that FA2 performance has remained above the achievable threshold of 95% since 1 April 2017.
All screening services that submitted data (140 out of 143) met the acceptable threshold of 90%. 137 services met the achievable threshold of 95% and 23 of them reported performance of 100%.

1.2 KPI FA3
There is no intention to publish FA3 by individual maternity service. We are reviewing the data with the aim of publishing it nationally in the future.
In Q1, 137 out of 142 screening services submitted data.
1.3 KPI FA4
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. After this time we will review the data with the aim of publishing it from the following year.

National performance of ST2 in Q1 was 41.3%. The national trend graph below shows that ST2 performance has dropped below above the achievable threshold of 50% for the first time since 1 April 2017.
Data suggests that while services were maintained, performance was affected for this KPI during COVID-19. This is not unexpected as technical guidance in place at the time stated that services could offer screening later than 10 weeks.
136 out of 142 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 1.4%. The national trend graph below shows that NB2 performance is at its lowest level since 1 April 2017.
Due to COVID-19, during this 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.
All 142 screening services submitted data.

5. Newborn hearing screening
5.1 KPI NH1: coverage
National performance of NH1 in Q1 was 93.7%. The national trend graph below shows that NH1 performance has dropped below the acceptable threshold of 98% in the last 2 quarters.
During the COVID-19 pandemic 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 64.7%. The national trend graph below shows that NH2 performance has dropped significantly below the acceptable threshold of 90% in the last 2 quarters.
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.

We recommend not to use NP2 data as a performance measure because of issues with data quality. Work to improve this data is ongoing through the NIPE data quality improvement project.
