The three core functions of public health, as defined by the National Institutes of Health in 1998, are assessment, assurance, and policy development. These include:

Assessment

Monitoring health status in order to identify health issues within the community

Investigation/diagnosis of health issues and hazards within the community

The Nurses' Health Study (NHS) is a collection of progressive studies investigating epidemiological and long-term health impacts from the dietenvironment, and disease development.

The study has been one of the greatest risk factors researchers have undertaken for major chronic illnesses.

Nurses' health studies have provided a wealth of information, knowledge, and discoveries about health and human well-being, including cancer prevention.

On the other hand, Health information refers to the data on a person's medical record, such as symptoms, diagnosis, treatments, and results.

A patient's health information can be evaluated separately to observe how their health has evolved, or as part of a wider dataset to determine whether a population's health has improved and how medical treatments can affect health outcomes.

The examples of health information that comes from Nurses’ Health Study includes:

  • surveys,
  • assessment and
  • monitoring

Surveys are a valuable tool for gathering health information and data from a standardized sample of individuals in order to gain a better understanding of a wider population.

Surveys can be conducted using a variety of methods, such as questionnairesin-depth interviews conducted over the cellphone, email, or in person.

The health information gathered is being accessed by health practitioners to check the validity of the information gathered.  

Given the limited resources available to promote global health, it has become increasingly vital for people who create and transmit health-related information to assess the effect of their efforts.

This is where monitoring of health information by NHS comes into play, such as:

  • providing a uniform set of metrics for assessing the reach, usefulness, usage, and effect of information gathered.
  • Simplify the selection and implementation of indicators to enhance monitoring and assessment.

Therefore, from the above explanation, we can understand the impact of the health information that comes from the Nurses' Health Study.
