Posted By Stevie C Hi all, I was asked this question today and I haven't had much experience with epidemiological analyses. If any one good give me some sound advice i would really appreciate it. Thanks in advance. Stevie

Posted By CFT Stevie To save me the job of duplicating one of my favourite explanations, see the link here; http://www.fao.org/Waird...ILRI/x5436E/x5436e04.htm If one assumes that ES is restricted to disease, we have our share of studies such as Asthma, Asbestos related, skin, and so on; we use the methodology ourselves from time to time but probably to be fair do not refer to it specifically as an epidemiological study although if the cap fits and everyone understands the terminology why not? A.N. Other organisation UK wide producing (whatever) which despite health surveillance and everything else ticked may have a substantial level of absenteeism to sickness/repetitive ill-health, what trend is there, what is the cause, are there repeats and similarities? What a surprise to find that perhaps 85% of the work force are all suffering the same problem/disease caused by whatever the study has revealed; it easily allows the investigator to address the root cause of the problem rather than permitting a degree of guess-work and time consuming trial and error which ultimately helps no-one. It can be addressed quickly on a grander sale which is relative to the problem. It can also be used in advance of any ‘likely’ occurrence/outbreak to examine possible consequence; this is extremely useful to Governmental related control measures for outbreaks. be one step ahead (proactive) v (reactive). Hope this helps some. CFT
