You can access NNAP data for the audit years 2014 to 2018 on NNAP Online. Data are presented at unit and network level.

Because not all neonatal units have been included in the audit for the whole of this time (for example Scottish units joined the audit in 2015) you may find that data are not available for a unit for a given year. If you have any questions about this, please contact the NNAP team at:

You can access the full details of the NNAP audit measures and standards via the NNAP web pages at:

In the 2017 and 2018 data reports, we report outlier analysis and main report measures using a “no imputation” approach. By this we mean that rates of adherence to standards, or rates of clinical outcomes are described for the babies where the outcome is known. Numbers of patients with missing data are presented alongside clinical data.

This means that the 2017 and 2018 results may not be directly comparable with results from 2016, 2015 and 2104 as displayed in the annual report, unit and network data sections and poster downloads. In previous years missing data were counted as negative outcomes or non-adherence to standards.

All outlier data and longitudinal outlier data are reported using the “no imputation” approach for all years, so are comparable.

You can use the longitudinal outlier analysis section to consider change in unit and network performance for the following measures; Antenatal steroids; Temperature on admission; Consultation with parents; ROP screening; Antenatal magnesium sulphate; Breastmilk feeding at discharge; Two-year follow-up.

Rates of encephalopathy are published for health boards and trusts in England, Scotland and Wales which may be of use in supporting local investigation of cases of encephalopathy. All results for this measure are reported by trust/health board of birth.

The denominator data for this measure are live births greater than 34 weeks gestational age by trust/health board. It is currently not possible to generate unit level encephalopathy rates due to lack of denominator data at hospital level in England and Wales. At the time of analysis, denominator data was not available for the current audit year, so rates are published for the three-year period up to the end of the previous audit year.

The outlier funnel plots show data from all the units or networks contributing to this measure to NNAP. For units, the rates displayed in the funnel plot are shrinkage estimates. For networks, they are the sample rates. In the NNAP outlier detection methodology, the distribution (location and dispersion) of the underlying compliance rates is estimated, and the results are used to improve the estimated compliance rates – these are the shrinkage estimates.

Units or networks are arranged on the horizontal axis according to their caseloads, smallest at the left-hand margin and largest at the right-hand margin. The vertical axis shows the rate associated with the audit measure -- for most measures, higher rates indicate better performance. Each unit or network is represented by a single dot. The standard, or the overall rate, is indicated by a horizontal solid line. The two blue curves delimit the rates that can be expected for a unit (or network) whose performance is equal to this standard.

A unit or network can use this graph to identify an opportunity for quality improvement. One way to do this is by finding a comparator unit or network that has performed much better, and comparing the clinical and other practices in these two units (or networks).

You can access copies of previous NNAP annual reports, including the parent/carer guide ‘Your baby’s care’, via the NNAP web pages at:

Yes, once you have chosen to view the annual summary results for any given network or unit via the Annual reports section of NNAP Online you will see an option for downloading a pdf report version of the results at the top left-hand side by clicking on the link titled "Download all data below as a PDF". You also have an option to download the results in a csv/excel format by clicking on the link titled "Download table as CSV data".

Please select the ‘unit poster’ tab within the blue column on the left-hand side of the page, select the year then your unit name from the drop-down list, then select ‘download PDF of poster’. Don’t forget to download poster two.

Due to rounding of the data to the nearest whole number, there may be a shortfall in the total combined value displayed within the graphs of 1%, or in very rare situations 2%.

No, the results that are available to view in NNAP Online are of an aggregated unit, network, unit type and national level. For some measures, masking is applied to unit level results to reduce the risk of deductive disclosure of sensitive information.
