Scottish Perinatal & Infant Mortality & Morbidity Report (SPIMMR)
Published: 25 March 2014
Scottish Perinatal and Infant Mortality and Morbidity Report
Annual reports on perinatal mortality in Scotland have been produced since 1977. The report now also includes information on late fetal deaths (losses from 20 to 23+6 weeks gestation), late neonatal and post-neonatal infant deaths. In recent years, information on certain congenital anomalies occurring in live births, stillbirths, miscarriages and terminations has also been included. In 2011, a more detailed data collection form was used and a new system for classifying the cause of death was introduced. The quality and completeness of information has improved and causes of death now reflect modern practice and knowledge.
The Scottish Stillbirth and Infant Death Survey and the production of the report, including quality assurance, are managed jointly by the Reproductive Health Programme of Healthcare Improvement Scotland and the Information Services Division of NHS National Services Scotland with collaboration from National Records of Scotland.
The 2012 SPIMMR is the last to be produced in this format. In January 2013, the Scottish Stillbirth and Infant Death Survey was replaced by a revised UK survey, MBRRACE-UK (Mothers and Babies Reducing Risk through Audit and Confidential Enquiries across the UK). This new collaboration was appointed by the Healthcare Quality Improvement Partnership (HQIP) for the national programme of work investigating maternal deaths, stillbirths and infant deaths. Funding is provided by the four UK departments of health.
Annual reports will be produced with the first report anticipated in 2015. All units in Scotland are now registered for the web based data collection process. It is planned that Scottish data will be separately analysed in addition to the UK report and will be used to inform the patient safety programme in maternity services.
Revisions and Updates
Revisions to the 2010 and 2011 SPIMMR reports - changes to funnel plots.
An error has been identified in the methodology used for plotting the x-axes in the stillbirth, neonatal death and congenital anomaly by NHS board of residence funnel charts. The funnel plots in both the 2010 and 2011 SPIMMR reports are affected by this error. This has resulted in the control limits, that is, the lines representing two standard deviations (2SD) and three standards deviations (3SD) from the mean, being incorrectly plotted on these charts.
It should be noted that the mortality rates for the NHS boards were correct and these have been correctly plotted along the y-axis of the funnel plots. The line plotted to represent the mean was also correct on the funnel plots. The impact of the revision of the control limits means that some data points will be re-positioned in relation to these lines on the charts. For example, in the 2011 report in Figure 9.1a, NHS Fife is more than 3 SD from the mean and on the corrected plot is now between 2 SD and 3 SD of the mean. For the majority of data points the change in position, relative to the control limits, is insignificant. However, in a small number of cases the re-positioned data point crossed from previously appearing below the 2 SD or 3 SD limit to now being above it. Similarly, for some NHS boards the re-positioned data point crossed from appearing above the 2 SD or 3 SD limit to below it.

Revised versions of the 2010 and 2011 reports have been placed on the ISD website on 25 March 2014.
An error was recently identified in Table 2.2 in the 2010 report. The rates quoted in the lower part of the table, under the column header "2005", were noted to be incorrectly reported at two decimal places. These data have been corrected and an updated version of the 2010 report placed on the ISD website on 26 March 2013.
