- Barriers to progress: miasma and the absence of a theory of cause — Miasma theory was wrong. Why did acting on it save so many lives?
- Nightingale, Scutari, and changes in nursing and hospitals — The death rate at Scutari fell from about 42 per cent to about 2 per cent. Who or what caused that?
- Pain, infection and bleeding; Simpson and chloroform — How can a genuine advance make outcomes worse?
- Chadwick, the 1848 Public Health Act, cholera and Snow — Snow proved cholera was waterborne in 1854. Why did it take a smell in 1858 to get anything built?
The teaching route this belongs to: Progress in the mid-19th century; Nightingale, Chadwick, Snow and Simpson — Changes in medicine — the lessons in order, with every gate.
Specification coverage
Paper 2, Section B — B2 Changes in medicine, c1848–c1948, key topic 1
Assessment objectives: AO1, AO2. Suggested learning time: 90 minutes.
Required knowledge
- Barriers to progress, especially the lack of understanding of causes of disease
- Florence Nightingale and changes in nursing and hospitals at Scutari
- Dangers in surgery: pain, infection and bleeding; the impact of Simpson and chloroform
- Problems and improvements in public health, including the work of Chadwick and the effects of the Public Health Act (1848), the cholera threat and the work of Snow
Required skills
- Explain and analyse using second-order concepts: causation, consequence, change, continuity, similarity, difference and significance
- Track change and continuity across the whole period, not just within one key topic
- Reach a supported judgement rather than describing events
How it is examined
- (a) 6 marks — “Explain TWO ways in which X was different from Y” (AO1 2, AO2 4)
- (b) 8 marks — “Explain TWO causes of…” (AO1 4, AO2 4)
- (c) 16 marks — significance or causation across the period, choice of two, with two bullet prompts (AO1 7, AO2 9)
Common mistakes
- Saying Snow discovered germ theory. He demonstrated cholera's transmission through water without knowing the mechanism — that distinction is the point.
- Reducing Nightingale to kindness. Her significance is administrative and statistical.
