Hi I turn shiny fell for UAB School of Medicine in this video I'm going to discuss the general design principles of cohort studies I'll talk about when they're useful, and I'll also discuss the limitations that they have in answering epidemiological questions so as a reminder of how study designs or organized studies can be either descriptive or analytic studies can be either experimental studies like randomized control trials or observational studies like cohort and case-control studies we're going to focus this video on cohort studies and their observation what observational means as researchers we don't intervene we just watch what happens to people naturally in the case of a cohort study watch to see what outcomes develop in these people as a further reminder primary research is broken up into randomized control trials the observational studies cohort and case-control studies and a couple other study designs were not going to talk about now the ordering of this hierarchy is important it goes in reverse order of bias, so the risk of bias is lowest and randomized control trials followed by cohort studies followed by case control studies so what our cohort studies, so cohort studies start out with a group of patients who are healthy they don't have the disease that were interested in and the patients are broken up into an exposed cohort and an unexposed cohort and then these two cohorts are followed forward in time for the development of disease, so this is a prospective cohort study now cohort is just a group of people it's nothing more than that so in this case we have an exposed cohort and an unexposed cohort now cohort studies can also be done retrospectively instead of starting at the present and going forward we actually go back in time assemble our exposed and unexposed cohorts come forward to the present time and look to see in each of these cohorts how many people have developed disease or not so why might we do a retrospective cohort well a couple of reasons one is if a disease takes a long time to develop we can go backwards in time break people up and to expose an unexposed cohort come forward in time till the present time has elapsed, so we've saved ourselves a lot of time the other thing that retrospective cohort studies are often done within is other studies that have already been done and the data is just sitting there, so you can go back and break people up into exposed and unexposed groups depending on your exposure of interest, so that's probably the two most common reasons that you see a retrospective cohort study still design the same way broken up on exposure status followed forward for the development of disease now cohort studies odds can be used to determine prognosis and harm, so prognosis is once people have a disease we look to see what happens to them and then harm is people who don't have disease, yet we look to see the risk or the rate of them developing new disease, so the same study design can be used in two...
