TROUGH TIME OF VANCOMYCIN AND AGE 2 Trough Time of Vancomycin and Age Research Question What is the factor effect in reaching goal trough of vancomycin? Design Studies and Subject Selection In the field of Epidemiology and Biostatistics, research design studies are separated into two groups namely observational and experimental. Under observational study design we will choose to employ the case-control approach. Therefore, a case-control study is regarded as an assessment under which two groups of individuals with different outcome are selected and compared on the merit of some underlining causal attribute. The main aim in a case-control study is to establish whether there is an association between exposure and the outcome. As such, in this case control study will investigate goal trough time for vancomycin as a function of age. The objective here is to establish association between age and tough time vancomycin[ CITATION Ren09 \l 1033 ]. With regard to experimental design studies, a retrospective study will be employed. Unlike a prospective design study, a retrospective study is performed after some of the individual have developed or attained the desired outcome. The investigator/researcher is therefore required to go back and identify a particular point in time when the participants had not developed the desired outcome and try to establish their exposure level at that instance. It is then the role of the investigator to determine whether a particular subject developed the desired outcome or not. And if he/she did develop the desired outcome, it is the responsibility of the investigator to establish when and why this took place[ CITATION Phi14 \l 1033 ]. In most instances, a retrospective study is undertaken when dealing with a group of individuals associated with an unusual or new treatment/ disease. Essentially, retrospective studies utilize
