Health forecasting

Health forecasting is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Health forecasting rather than just read about it. In short: Health forecasting is a new health care discipline initiated by the Met Office when Dr William Bird, a GP, became its first clinical director in 2002. It is currently the subject of an innovative project run jointly by the Met Office and the National Health Service (NHS) in the United Kingdom.

Key takeaways

Health forecasting belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Health forecasting to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Health forecasting from memory before moving on to harder problems.

Reference excerpt

Health forecasting is a new health care discipline initiated by the Met Office when Dr William Bird, a GP, became its first clinical director in 2002. It is currently the subject of an innovative project run jointly by the Met Office and the National Health Service (NHS) in the United Kingdom. The natural environment affects human health. There are many cases in which the weather has a direct or indirect effect on the health of an individual. These include:

Heat, which can cause up to a 30% increase in mortality amongst the elderly and very young. Prevention can save lives. Cold, which contributes to 30–40 thousand deaths each winter. Prevention consists of keeping active, eating well, dressing up appropriately, especially hat, gloves and coat when outside and keeping the indoor temperature at 21C. Thunderstorms, which can cause asthma epidemics if they occur during high levels of either pollen or fungal spores in the summer. Low boundary layers, which may increase the way viruses are transmitted by increasing the amount of stagnant air. Health forecasts help professionals and patients know when and where there is a risk of illness. Through this understanding, preventative action can be taken and health care capacity (i.e. hospitals and doctors) managed to reduce illness and death. The main strand of the health forecasting project is forecasting the risk of exacerbation for people with chronic obstructive pulmonary disease (COPD). COPD health forecasts are used to drive the provision of anticipatory care to people with COPD, helping them achieve their potential for independence and wellbeing. The service is being run in around 30 primary care trusts with over 20,000 patient registered to receive alerts. In many areas alerts are provided by an automated interactive telephone. Evidence from several evaluations of the service has shown around a 20% reduction in COPD related emergency admissions for practices using the service. On 26 February 2007, the project won in the Innovative Service Award category at the Health and Social Care Awards 2006. The Health and Social Care Awards are run annually in partnership between the Department of Health and the NHS Institute for Innovation and Improvement and are the most important opportunity within the NHS and social care to identify, recognise and reward excellence in the provision of care at the front line. The specific award recognises an innovative, new or improved service that is benefiting the delivery of health care for patients, users and carers. In 2011 the Shanghai Meteorological Service and Shanghai Municipal Public Health Bureau jointly launched a health meteorological service that includes health forecasting for conditions such as colds, asthma, COPD and a heat health warning service. This will be developed based on a considerable amount of research to provide a service to improve healthcare in Shanghai.

Worked examples

Example 1 — a first encounter with Health forecasting

Start with the simplest possible case. Write down what Health forecasting claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Health forecasting before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Health forecasting ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Health forecasting

In research: Health forecasting appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Health forecasting in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Health forecasting is common in secondary-school and first-year university syllabi. It links to neighbouring topics Public health in the United Kingdom, so understanding it makes those chapters shorter.
In everyday life: Look for Health forecasting outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Health forecasting in simple terms?

Why does Health forecasting matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Health forecasting?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
