Population-based nursing: caring for individuals, families, communities and systems
- Fundamental
Population-based nursing looks after the health of a whole group, not only the person who consults, and acts where people live, study and work.
What it is
Population-based nursing takes a defined population as its client: a neighbourhood, a rural district, a school or a group at higher risk. It starts from a systematic assessment of the community's needs and assets, looks at the social determinants of health and then acts at several levels at once: with individuals and families, with the community as a whole, and on the systems (rules, services and environments) that shape everyone's health. The public health intervention wheel names these three levels of practice. In Colombia, the basic health teams organise this work by micro-territory and deliver collective interventions in the everyday settings where people live: the home, schools, the community, workplaces and institutions.
Key points
- A community health needs assessment is a systematic process to identify and analyse needs and assets, rank them and plan action.
- Health disparities are differences linked to social, economic or environmental disadvantage; health inequities are avoidable differences within and between communities.
- Interventions can be clinical (one to one, in a care setting), behavioural (changing habits) or environmental (laws, policies or the physical environment).
- Two prevention frameworks guide planning: primordial to quaternary prevention, and universal, selective and indicated prevention.
Components
- Individual and family level: care, teaching and follow-up for people and households at risk, for example during a home visit.
- Community level: work with the whole group or a sub-population, for example a blood pressure screening day in a neighbourhood.
- Systems level: changes to the rules, services and environments that affect everyone, for example smoke-free spaces or safe water.
- Vulnerable sub-populations: groups inside the community with higher risk, identified from the data and asked for their own views.
What it is for
- Reaches people who never come to the health centre.
- Lets the team set priorities from community data, not only from who happens to consult.
- Acts on the causes in the environment and in policies, not only on illness once it appears.
In nursing practice
- Start with the data that already exist (secondary analysis), then collect new data with forums, focus groups, windshield surveys, surveys or observation.
- Compare trends over time and with similar communities, and look for vulnerable sub-populations inside the averages.
- Involve the target population in the assessment and in planning; this is part of culturally competent care.
- Write outcomes that are specific, measurable, achievable, realistic and time-bound, and later check whether the community's health improved.
- In a Colombian basic health team, each micro-territory has an assigned nursing assistant, and each household contact is a chance to review the whole family.
Common mistakes
- Counting only the people who consult and missing those who never come.
- Planning for the community instead of with it.
- Looking at averages and missing the sub-groups with the highest risk.
- Treating individuals one by one when the cause lies in the environment or a policy.
Test yourself
Think of the answer, then tap the question to see it.
What are the three levels of practice in population-based nursing?
The individual and family level, the community level and the systems level.
Is changing a local rule to create smoke-free spaces a clinical, behavioural or environmental intervention?
Environmental: it changes laws, policies or the physical environment for the whole community.
What is the first step before collecting new community data?
Reviewing the data that already exist (secondary analysis), so the team does not repeat work already done.
In which five settings does Colombia deliver collective interventions?
The home, schools (educational setting), the community, workplaces and institutions.
