Clinical Research in Infectious Diseases
Clinical research (research involving human subjects) may include the evaluation of therapies, treatments, devices, medications, surgeries, and/or diagnostic tools. The results from clinical research advance the efficacy and safety of new treatments and directly improve patient care and quality of life.
The Division of Infectious Diseases has a research team whom coordinates all clinical research with the Infectious Diseases clinical faculty. In addition to clinical research, the faculty members conduct laboratory research both at the UC Davis Medical Center and on the UC Davis Campus.
Each type of clinical research plays an integral part in strengthening our knowledge of certain diseases or conditions. With clinical research, we can implement better techniques to diagnose, treat, and prevent human diseases and conditions.
Clinical Trials
The majority of clinical research consists of clinical trials, which may be sponsored or funded by physicians, foundations, federal health agencies (such as the National Institutes of Health), pharmaceutical companies, or university grants.
A clinical trial is a study that looks for new ways to prevent, detect, diagnose, and/or treat a disease or condition. Clinical trials are research projects that have two main objectives in mind: patient safety and disease treatment/prevention. Patients are at the forefront of medicine when they choose to be a participant in a clinical trial. Not only are they contributing to the medical and scientific understanding of their disease, but they also have access to the newest treatments.
Observational Study
This type of study observes people or specific outcomes are measured and recorded. Clinical data is typically only collected and there isn’t any experimental treatment. Another term for these types of studies are retrospective reviews or registry study.
These studies help us understand specific diseases and to identify any causal relationships. Participating in these studies provide important information that has the possibility to help future patients.
Basic Research
These studies collect biological samples from volunteers who are either healthy or suffer from a specific condition. Subjects typically do not directly benefit from participation but their participation has the possibility to help future patients.
Clinical research studies are very different from regular medical care. Your primary care physician will diagnose and treat you for an illness or condition. Clinical researchers gather new information to help improve future medical care.
