Summary

Looking at information on the numbers of national data opt-outs and how this might affect data. 

9.1: National data opt-out publication

A national data opt-out publication provides statistics on the volume and spread of national data opt-outs. The publication gives a breakdown of national data opt-outs against different demographic metrics including age, gender, GP practice, Clinical Commissioning Group (CCG) and Lower Layer Super Output Area (LLSOA).  This is updated annually or when the national data opt-out rate changes by more than 0.1 per cent.

9.2: Bespoke analysis

Health and adult social care organisations may wish to undertake more bespoke or specific analysis to understand the potential impact of national data opt-outs on the data that they disclose or receive. Any analysis needs to meet the following principles:

  • undertaken in a way that prevents the identification of an individual with a national data opt-out, for example by comparing counts where opt-outs have and have not been applied. National data opt-outs must not be directly linked to other datasets.
  • dimensions analysed independently of each other/small number of dimensions combined to reduce risks of re-identification
  • resulting analysis must be fit for publication/anonymised in line with the ICO Code of Practice on Anonymisation
