https://communities.sas.com/t5/SAS-Health-and-Life-Sciences/adhoc-reports/m-p/39963#M1264 Hi:<BR /> It means that somebody needs a one-time report. It could be anything:<BR /> <BR /> How many patients does doctor XYZ have?<BR /> If doctor XYZ dropped out of the trial, what's the age distribution of the patients who are left?<BR /> Who are the patients that had batch 12345 of the drug? <BR /> If this hurricane hits Florida, how many doctors and patients are affected?<BR /> <BR /> These are not questions that you can program in advance, but a general knowledge of SAS procedures will help you satisfy these kinds of requests. I'm sure there are many other examples -- the thing is that these requests are not really predictable -- it could be anything -- that's why they're called "ad-hoc".<BR /> <BR /> cynthia Fri, 22 Aug 2008 17:36:23 GMT Cynthia_sas 2008-08-22T17:36:23Z https://communities.sas.com/t5/SAS-Health-and-Life-Sciences/adhoc-reports/m-p/39960#M1261 Hi<BR /> <BR /> What do you mean by Pooled datasets and Adhoc reports?<BR /> How they are related to clinical trials and how they are created in clinical reports?

Because the contributing trials often have different data specifications, pooling involves a lot of data manipulation to get common variable definitions.
