The cost of printed information can vary enor- mously 250mg chloromycetin visa, and the key variable is knowledge of the techniques discount 250 mg chloromycetin overnight delivery. Put another way, you can spend an awful lot of money and produce something that is unreadable, and spend next to nothing and produce something that does precisely what you intended. Usually they will be happy to advise out of goodwill; they may even find it therapeutic. Ignore the views of your colleagues – their comments will almost certainly be criticisms of the content rather than judgements over whether you are getting the right messages across. Test any information on the target audi- ences – ask your patients to read it and then ask for their comments. You could gently probe them to see whether they have taken home the messages that you intended them to take home (see payoff). Remember, this is not a test of your knowledge, but an attempt to put across some useful bits of information to people who are often frightened and confused, and delighted when they receive clear advice. Patronizing language One of the problems of writing, particularly for patients, is that if you use long words you are criticized for not being concise – and if you use short ones you are criticized for being patronizing. The tabloids, for instance, use this kind of language – and are rewarded by millions of readers daily. Where language becomes patronizing is not when the words are simple, but when certain phrases are introduced that define the reader as an outsider. In other words, there is an assumption that the reader will not understand. The solution, I suspect, lies not in changing our style but in having a more robust attitude. If it is your target readers who are complaining, then you can easily make changes. But most of the accusations tend to come from those who have appointed themselves to be their spokespeople (see false feedback loop). Peer review The system of peer review started in the mid- 17th century when scientists decided that, before they published an article, they should ask the opinion of others working in the same field. The assumption is that exposing work to the criticism of others will identify shortcomings and improve the quality of published material. It is a cornerstone of modern science publishing, with complicated structures developed to carry it out, and more recently a growing peer review research industry giving it added status. Most papers go through to the second stage, which is assessment by others in the field who are known to the journal.
