During forming a group of cases, it is necessary to apply strict, objective criteria for the result. You should be sure of the homogeneity of the result because similar illness or effects may have different risk factors, for example not all diseases of the intestinal infections that are detected in the population under study only in the presence of diabetic syndrome can be selected for the study. Observational studies proved, that case-control studies have less reliability than cohort studies. This is not entirely true: a well-organized case-control study in a number of situations can provide much more reliable results than cohort studies. The main stages are:.

Case study design | definition of case study design by Medical dictionary
A case study is a research method that relies on a single case rather than a population or sample. When researchers focus on a single case, they can make detailed observations over a long period of time, something that cannot be done with large samples without costing a lot of money. Case studies are also useful in the early stages of research when the goal is to explore ideas, test, and perfect measurement instruments, and to prepare for a larger study. A case study is unique within the social sciences for its focus of study on a single entity, which can be a person, group or organization, event, action, or situation. It is also unique in that, as a focus of research, a case is chosen for specific reasons, rather than randomly , as is usually done when conducting empirical research.

Metrics details. The case study approach allows in-depth, multi-faceted explorations of complex issues in their real-life settings. The value of the case study approach is well recognised in the fields of business, law and policy, but somewhat less so in health services research.
