I've developed an interest in the Government's inability to get its hands on health data. Guildford MP and Shadow Health Minister Anne Milton has uncovered another case with a written question:
To ask the Secretary of State for Health on how many occasions electro-convulsive therapy was administered to a mental health patient (a) in total and (b) as part of compulsory treatment in each of the last five years. 
|Total and average number of procedures for electro convulsive treatment per patient where the relevant operative procedure code (OPCS-4 code= A83) recorded in either main or in any of the secondary operative procedure fields 2003-04 to 2007-08, England|
|Total Procedures||Patient count||Average procedures per patient|

We do not have the data requested about ECT and compulsory treatment. However, patients who are detained under the Mental Health Act 1983 cannot generally be given ECT without their consent, unless it is authorised by a Second Opinion Appointed Doctor (SOAD). The following table shows the number of second opinion requests in England and Wales for ECT received in each calendar year followed by the percentage of those requests that resulted in the Second Opinion Appointed Doctor issuing a statutory certificate authorising ECT.
