Epidemiology and Nursing; How Nurses Use It in their Practice

Posted: July 26th, 2022

Epidemiology and nursing are vital in medicine and society’s advancement. Even though they are two different fields, they depend on one another to build a better healthcare system. Nurses take care of patients and ensure their wellbeing.
Through epidemiology, they can track diseases and risk factors and create ways to mitigate health problems before they occur. It also allows them to research and use the findings to build better systems.

What is Epidemiology?

Epidemiology is the study of disease in populations. It is a branch of medicine that deals with incidence, distribution, and control of diseases. Nursing, on the other hand, is a profession that provides care for patients.

Principles of Epidemiology

There are four basic principles of epidemiology:

1. Disease occurs in populations and not in individuals.

The study of epidemiology is crucial because it helps identify risk factors for diseases. It also helps to develop strategies for preventing and managing diseases.

2. The health of a population depends on its ability to resist or recover from the disease.

Identify some of the determinants of health, such as genetics, environment, lifestyle, and access to healthcare.

3. The distribution of diseases in populations is affected by many factors.

Factors that may affect the distribution of diseases include age, sex, race, and socioeconomic status.

4. Disease prevention is more effective than treatment.

This principle emphasizes the importance of preventing disease rather than treating it. Disease prevention strategies include vaccinations, early detection, and lifestyle changes.

4. The distribution of disease in a population is described by measures of frequency.

The study of disease requires the collection of data.

Epidemiological studies identify risk factors for disease.

Epidemiology Study Designs

There are three main types of epidemiological study designs: observational, experimental, and quasi-experimental.

1. Observational studies

2. Experimental studies

3. Quasi-experimental studies

Observational studies describe the distribution of disease in a population and to identify risk factors for disease. 

Experimental studies test cause-and-effect relationships. 

Quasi-experimental studies are similar to experimental studies, but do not use randomization. They evaluate interventions.

The Relationship Between Epidemiology and Nursing

There is a close relationship between epidemiology and nursing. Epidemiological studies provide information that improve the care of patients. For example, epidemiological studies can identify risk factors for diseases. This information can develop interventions to prevent or treat these diseases.

Nurses play a vital role in the implementation of epidemiological studies. They can collect data on patients that are useful in these studies. Nurses can also provide care for patients who are participating in these studies.

Nurses’ Role in Epidemiology

Curative Role

Healthcare and cure requires the collaboration of all health workers. Nurses play an active role in providing care and administering medicine to patients.

Preventative Role

Nurses spearhead surveys and other methods that investigate risk factors that cause illnesses in society. They also tend to patients by giving primary care they need.

Promotive

Nursing promotes patient well-being. They also teach the general public about health risks and how to stay healthy. Nurses

Rehabilitative

Nurses play an active role in the rehabilitation of the sick. They play an active role in the well-being of patients and seeing to it they recover and

Epidemiology and nursing are two vital disciplines that work together to improve the health of populations.
