Is case series the same as case study?
Case Study / Case Report / Case Series A case study, also known as a case report, is an in depth or intensive study of a single individual or specific group, while a case series is a grouping of similar case studies / case reports together.
What are case series studies?
From Wikipedia, the free encyclopedia. A case series (also known as a clinical series) is a type of medical research study that tracks subjects with a known exposure, such as patients who have received a similar treatment, or examines their medical records for exposure and outcome.
How many patients are in a case series?
Conclusions. The concept of “case series” is not well defined in the literature and does not reflect a specific research design. We suggest that a case series should have more than four patients while four paitents or less should be reported individually as case reports.
What is the difference between a case series and a cohort study?
The only difference between cohort studies and case series in many definitions is that cohort studies compare different groups (i.e., examine the association between exposure and outcome), while case series are uncontrolled [3,4,5].
What is the main limitation of a case series?
There are several important disadvantages of a case series. First, if the report or series is retrospective, it will depend on the availability and accuracy of the data records. Second, a case series is subject to selection bias because the clinician or researcher self-selects the cases.
What are the advantages of case series?
The biggest advantage is that case series are feasible study designs, are easy to conduct and require less time and financial resources than randomised-controlled trials, case-control, or cohort studies. However, readers need to be conscientious of the inherent biases in case series, particularly selection bias.
What are case series good for?
Case series is an observational, descriptive research design. It is most useful for describing the potential effectiveness of new interventions, for describing the effectiveness of interventions on unusual diagnoses, and for describing unusual responses (either good or bad) to interventions.

What makes a good case report?
Generally, a case report should be short and focussed, with its main components being the abstract, introduction, case description, and discussion. This article discusses the essential components of a case report, with the aim of providing guidelines and tips to novice authors to improve their writing skills.
How are case studies and case series selected?
If a comparison group is included, a relative risk can also be calculated. Patients with a particular disease or disease-related outcome are sampled. Case series exist in 2 types: 1. Sampling is based on a specific outcome and presence of a specific exposure. Cases are selected on the basis of a striking association between exposure and outcome.
What’s the difference between a cohort study and a case series?
The term “enables/can” means that a predefined analytic comparison is not a prerequisite (i.e., the absolute risks per group and/or a risk ratio are provided). Instead, all studies for which sufficient data are available for reanalysis to compare different exposures (e.g., sufficient data in the publication) are classified as cohort studies.
What’s the difference between case series and descriptive study?
case series is descriptive study, the observational study , observes Experience of a group of patients with a similar diagnosis,Generally report on new/unique condition,May be useful for rare disorders.
When do you use case series in neurosurgery?
Case series (CS) are well-known designs in contemporary use in neurosurgery but are sometimes used in contexts that are incompatible with their true meaning as defined by epidemiologists. This inconsistent, inappropriate and incorrect use, and mislabeling impairs the appropriate indexing and sorting of evidence.
