Living with chronic illness: self-management and the nurse's role
- Fundamental
A chronic illness lasts for years; the person manages it every day, and the nurse helps them gain the knowledge, skills and confidence to do it.
What it is
Noncommunicable diseases (cardiovascular disease, cancer, chronic respiratory disease and diabetes) cause about three in four non-pandemic deaths worldwide, most of them in low- and middle-income countries. Their main shared risk factors are tobacco, physical inactivity, harmful use of alcohol and unhealthy diet. A chronic illness is not cured with one treatment: the person lives with it and takes daily decisions about medicines, food, activity and symptoms. Self-management is the person's active, day-to-day management of their condition. The nurse's role is to support it: assess what the person already knows and can do, teach in small steps, agree realistic goals, help with coping and involve the family and the community programmes.
Key points
- Chronic illness lasts a long time, often for life, and usually has periods of stability and of worsening.
- Self-management covers knowledge of the illness, taking treatment as agreed, recognising and acting on symptoms, and lifestyle changes.
- Early detection, treatment and palliative care delivered through primary care are key parts of the response.
- Chronic stress and illness affect mood; adaptive coping and social support protect health.
- The family often shares the burden of care and needs teaching and support too.
Components
- Knowledge: what the illness is, what the treatment does and what warning signs to watch for.
- Skills: for example, measuring blood pressure or glucose at home, using an inhaler, caring for the feet.
- Confidence (self-efficacy): believing one can carry out the changes.
- Support: family, peers, community and health programmes.
- Follow-up: regular check-ups and a clear plan for what to do when symptoms worsen.
What it is for
- Fewer complications and fewer hospital admissions.
- More autonomy and better quality of life for the person.
- Shared decisions between the person and the health team.
In nursing practice
- Ask first what the person already knows and does; correct misconceptions without blame.
- Teach one topic at a time and check understanding with teach-back.
- Agree one or two concrete, achievable goals per visit rather than a long list of changes.
- Assess coping and mood: sadness, denial or anger after a diagnosis are common and may need support or referral.
- Connect the person with the institution's chronic-disease programme and community resources.
Common mistakes
- Giving a lot of information at once and assuming it was understood.
- Labelling the person as «non-adherent» without asking about cost, side effects, beliefs or access.
- Setting the goals for the person instead of with them.
- Forgetting the family and the person's emotional response to the illness.
