Clinical research is a branch of medical science that determines the safety and effectiveness of medication, devices, diagnostic products, and treatment regimens intended for human use. These may be used for prevention, treatment, diagnosis, or for relief of symptoms in a disease.

Clinical trials are conducted to allow safety and efficacy data to be collected for new drugs or devices. These trials can only take place once satisfactory information has been gathered on the quality of the product and its non-clinical safety, and Health Authority/Ethics Committee approval granted in the country where the trial is taking place.

Investigator Initiated Study

Many physicians in the department are involved in investigator-initiated studies. An investigator initiated study is an application where the investigator is conducting the study and acting as the sponsor. The investigator both initiates and conducts, alone or with others, a clinical trial, and under whose immediate direction the investigational product is administered to, dispensed to, or used by a subject. An investigator initiated study does not include a corporation or an agency. These are protocols designed and written by our physicians and may receive funding from outside sources such as pharmaceutical companies, professional societies, or government agencies. The obligations of the investigator include both those of a sponsor and those of an investigator.

Retrospective Study

A retrospective study, also called a historic study, is a medical research study in which the medical records of groups of individuals who are alike in many ways but differ by a certain characteristic (for example, female nurses who smoke and those who do not smoke) are compared for a particular outcome (such as lung cancer).
