Morning y'all, Am working on something, and I wondered if anyone had seen any research that might have sought to quantify the number of people diagnosed or seen, with e.g. severe, moderate, mild ME/Whatever? I think that generally speaking, as patients, we tend to consider approximately 25% of patients to be 'severe' at any one time and work from there, but I recently looked at a costing's template for use with the NICE Guidelines and noticed that this indicator for service provision was set at 10% There are several reasons for this being set so relatively low, and the figure can be adjusted upwards, but I wondered if there had been any reported evidence you might have seen relating to prevalence of categorisation? I did have a wee look at the 25% Group's website but couldn't see anything relating to their determination/estimate: http://www.25megroup.org/ If not I'll ask them and see if they know of anything. Cheers Oh here's the NICE Guidelines implementation costings template I was talking about: http://guidance.nice.org.uk/CG53/CostingTemplate/xls/English Look at Step Two. Mods: I didn't know where to pop this one - so please move if necessary. Thanks.
