Application Of Experimental Research In Health

Application Of Experimental Research In Health

Broadly speaking, the application of experimental research methods in the field of Health there are two forms, namely: intervention research and clinical research or better known as a clinical trial. Intervention research is actually similar even the same as experimental research has been described earlier. However, in addition to the explanation described briefly below, clinical trials are described in other chapters of this book.

I. Intervention Research

As with clinical research used in medical clinics, intervention research is used in the field of Public Health (public health). In other words, intervention research is experimental research imposed on society as a unified set of subjects. 

Researchers perform manipulation or provide treatment not with an individual subject approach as in clinical research, but with a group approach. Treatment is given in the form of a package imposed on the subject collectively in the community. The effect of treatment was observed using individual and Group analysis units.

2. Preventive Intervention Research

This study tries to study the relationship of risk factors with the incidence of a disease by providing treatment or manipulation of these risk factors in the subject. Although the effects of a treatment given collectively to individuals in the community can be observed with an individual approach, the observation is more often done with a group approach. 

Example: treatment or intervention in the form of immunization counseling for mothers in a community, the effect will be seen by increasing immunization coverage of children under five; treatment in the form of “PSN” (eradication of mosquito nests) in a village, the effect will be seen by decreasing cases of dengue fever in the village.

3. Curative Intervention Research

These experimental/interventional studies try to provide treatment for the development of a disease. In other words, this study will reveal whether the Natural History of a disease can be manipulated or specifically intervened. Treatment in this type of research is in the form of management of curative measures to the community to overcome community endemic diseases. 

Treatment can be in the form of counseling to the community in dealing with (overcoming) the disease and can be in the form of mass treatment. Examples: mass treatment of worms in children under five in order to reduce the prevalence of stomach worm disease; counseling for regular treatment at the pulmonary tuberculosis clinic in order to reduce the prevalence of pulmonary tuberculosis patients.
