Rapid responses are electronic letters to the editor. They enable our users to debate issues raised in articles published on thebmj.com. Although a selection of rapid responses will be included online and in print as readers' letters, their first appearance online means that they are published articles. If you need the url (web address) of an individual response, perhaps for citation purposes, simply click on the response headline and copy the url from the browser window. Letters are indexed in PubMed.
Most people working in the NHS recognise that there will be reorganisations every few years. This costs money, and, as Francis pointed out in his report on the Mid Staffordshire hospitals, can contribute to deaths. In the past 30 years, I do not believe that any reorganisation has truly benefitted the NHS. They are, however, great for politicians and managers to improve their CVs and distract attention from the core problems of the NHS, increased patient demand and expectation, and the rise of defensive medicine.
As Einstein almost certainly did not say, "Insanity is doing the same thing over and over again and expecting different results."
