Biomedical and behavioral research necessary to improve human health and medical care depends on the participation of human subjects. The usual justification offered for paying research subjects is that payment facilitates the timely recruitment of an adequate number and type of subject.
Paid clinical research studies refers to all research carried out on humans (healthy or sick people). It focuses on improving knowledge of diseases, developing diagnostic methods and new treatments or medical devices to ensure better patient care.
TYPES OF CLINICAL RESEARCH:
OBSERVATIONAL STUDIES:
They improve the knowledge of the disease and its evolution over time. They are carried out within the framework of the follow-up of the patients in the reference centers. They also contain the natural history studies.
INTERVENTIONAL STUDIES:
Interventional studies, also called experimental studies, are those where the researcher intercedes as part of the study design. Additionally, study designs may be classified by the role that time plays in the data collection, either retrospective or prospective.
Each clinical study has a protocol, or a list of guidelines or a research plan. Included in the protocol is the goal or purpose of the study, how many participants will be enrolled, what will be done at every study visit, and the plan for data analysis. The protocol also identifies how researchers will define outcomes. For example, a study may say that if 30% of participants improve by a minimum of 60% then the drug will be considered effective. The protocol will also include the results from animal models and previous phases of the study; eligibility and exclusion criteria for participants; a schedule of the tests and gathered from the volunteers; and the length of the study.
RISK FACTORS OF CLINICAL RESEARCH:
There are always risks and potential benefits to participating in a clinical study. The risks may include:
Time commitment
Frequent drawing of blood
Unknown side effects of the treatment,
No immediate benefits
Potential benefits may include:
Additional care and attention from the research team
Access to experimental and new treatments
Knowing that the knowledge gained may benefit others in the future.
