Growth Assessment Protocol (GAP)                 GAP Gazette December 2021

The Perinatal Institute has put together a comprehensive programme which is offered to units already using the GROW software
and new units who now want to implement GROW. The following links give details of the programme: GAP SLA

GAP is based on the following key elements:

  1. Evidence based guidance and risk assessment algorithms
  2. Training and accreditation of all staff involved in clinical care
  3. Implementation of customised GROW chart and audit tool
  4. Rolling audit and benchmarking of performance

Rationale

• Most 'unexplained' stillbirths were growth restricted    • Customised charts and appropriate protocols should be used   
• Most stillbirths with IUGR are avoidable    • Standardised FH measurement and referral improves detection      
• A/N detection improves outcome and reduces SB    • In high risk pregnancy, serial scans improve detection   

Effect on Stillbirth

A co-ordinated growth assessment programme has reduced ONS stillbirth rates in three English regions with high uptake (West Midlands, Yorkshire & The Humber, North East). For detailed analysis, see BMJ Open 2013 and J Public Health 2014

The reduction is mainly in stillbirths with IUGR                             The Times Leading Article

According to the latest (2020) ONS figures, stillbirth rates in England have fallen consistently for 9 years to 3.80/1000.

This represents a 29.0% reduction from the 2000-09 (10 year) average of 5.35, and equates to 1,022 babies saved per year.

The recently published 10 year analysis of unit level ONS data in England doi.org/10.1002/uog.22187 showed that:

  • There was an overall decline, associated with better protocols & awareness
  • NHS Trusts that fully implemented the GAP programme achieved a larger reduction
  • Steepest drop was observed in GAP units with best SGA detection rates
  • The study also highlighted that there is much more room for improvement!
