Barriers to Progress
poor understanding of disease
many doctors believed in miasma theory (disease caused by bad air)
little knowledge of germs and how infections spread → treatments were ineffective and harmful
Florence Nightingale
Nightingale improved nursing standards during the Crimean War
emphasised cleanliness, ventilation, and organisation in hospitals
trained nurses professionally, improving the quality of care
→ her work changed attitudes towards hygiene in medicine, using statistics to demonstrate the importance of sanitary conditions
Scutari Hospital
Nightingale worked at the military hospital in Scutari during Crimean War, where conditions were initially poor with overcrowding, dirt, and diseases
she introduced better sanitation: clean water, waste removal, ventilation
→ death rates fell significantly
Problems in surgery
Surgery in the mid 19th century was extremely dangerous
patients suffered severe pain as anaesthetics were not yet developed or widely used
infection was common due to unclean instruments and poor hygiene
blood loss was a major risk, as techniques to control bleeding was limited
James Simpson’s introduction of chloroform in 1847
a form of anaesthetic to reduce pain during surgery
→ made operations more tolerable for patients, allowed surgeons to take on longer and more complex procedures
however, early use had risks such as incorrect dosage and occasional death
Public Health problems
rapid industrialisation led to overcrowded cities with poor living conditions
housings were cramped, limited access to clean water and proper sewage systems
diseases such as cholera were common due to contaminated water and waste
Edwin Chadwick 1842
investigated living conditions in towns and cities to form a report in 1842
he argued that disease was linked to poor sanitation and poverty
suggested to improve drainage, sewage, and clean water
→ his work influenced public health reform and government action
(he still supported miasma theory rather than germ theory)
Public Health Act 1848
first attempt to improve public health
set up a Central Board of Health to oversee improvements
local authorities were encouraged but not forced to improve sanitation
measures included better drainage, sewage systems, and a clean water supply
→ its impact was limited as it was not compulsory and faced resistance
Cholera threat
caused widespread death in overcrowded industrial cities
exposed major weaknesses in public health systems
governments faced increasing pressure to act
John Snow 1854
investigated the cholera outbreak, mapped cases and linked to the Broad Street pump
he removed the pump handle and it reduced the spread of disease → proved that cholera was water-borne, challenging miasma theory
(his ideas were not widely accepted)
Extent of improvements (benefits)
anaesthetics (chloroform) reduced pain in surgery
increased public health awareness due to work of individuals like Chadwick and Snow
some government action began (1848 Public Health Act)
hospital conditions improved through Nightingale’s reforms
Extent of Improvements (limitations)
miasma theory remained dominant, limiting understanding
germ theory had not yet been accepted
public health reforms were not compulsory
surgery still faced problems like infection
Louis Pasteur 1860s
carried out experiments that proved microorganisms caused decay and disease
showed that germs in the air caused contamination → germ theory developed
his ideas challenged miasma theory
Impact of Germ theory
transformed understanding of disease by identifying microorganisms as the cause
provided scientific explanation for infection & illness
→ acceptance was slow, but still laid the foundation for later medical advances
Jospeh Lister
applied Pasteur’s germ theory to surgery and used carbolic acid to clean wounds, instruments, and operating theatres
this reduced the number of germs entering surgical sites, preventing infections
Impact of Antiseptic Surgery
significantly reduced infection rates after surgery
death rates fell
surgeons are more confident to perform longer, more complex procedures
→ however, antiseptic methods were difficult and unpleasant to use
Public Health Act 1875
made public health improvements compulsory for local authorities
councils were required to provide clean water, sewage systems, street cleaning
improved living conditions, showed stronger commitment from government
Increased government involvement by the 1870s
laws become more enforced than optional
local authorities were given the responsibility to improve sanitation
→ reflected growing acceptance of the need for intervention
Later work of Florence Nightingale
improved hospital design, focusing on ventilation and cleanliness
established professional nurse training programme → raised standards in British hospitals
Elizabeth Garrett Anderson
first woman to qualify as a doctor in Britain
established opportunities for women in medicine → opened a hospital for women and children staffed by women
Importance of Technology
supported developments such as improved surgical tools and antiseptic methods
better equipment made it easier to apply new medical knowledge into practice
→ Technology was not the main driver of change, it was supportive
Robert Koch
Koch built on Pasteur’s work to identify specific bacteria that caused particular diseases
He discovered the microbes responsible for tuberculosis, cholera, and anthrax
developed methods for staining and growing bacteria → allowed scientists to link specific pathogens to specific illnesses
Bacteriology
study of bacteria and how they cause disease
led to more targeted prevention methods (early vaccines)
supported more accurate diagnosis of diseases
Aseptic surgery
preventing germs from entering wounds in the first place
sterilised instruments, wore gloves, and cleaned operating theatres
→ reduced infection rates during and after operations
Growth of laboratory-based science
medicine increasingly relied on laboratory research and experimentation
scientists used microscopes and controlled experiments to study bacteria
→ more accurate identification of disease causes (more evidence-based approach in science)
Paul Ehrlich
“magic bullets” - chemicals that target specific diseases
built on bacteriology and chemical research
He created Salvarsan (606), an early treatment for syphilis
Blood transfusions
doctors began to understand the importance of blood loss
some improvements were made in transferring blood between patients
→ knowledge of blood groups was still limited until 1901
Marie Curie
researched radioactivity
X-rays allowed doctors to see inside the body, which improved diagnosis of fractures and internal problems
used in early cancer treatments
Liberal Reforms 1906-11
1906, Education (Provision of Meals) Act - provided free school meals for poorer children
1907, Education (Administrative Provisions) Act - medical inspections in schools
1908, Children’s Act - protect children’s welfare and health
1908, Old Age Pensions - financial support for the elderly, improving living conditions
National Insurance Act 1911
Provided health insurance for workers
gave access to doctors and sickness benefits
→ it didn’t cover all groups, such as dependants
First World War
created urgent demand for improved medical care and treatments
developed new techniques: better surgery, blood transfusions, infection control
Advances in surgery for Wounds and Trauma
WW1 led to new types of injuries and severe trauma
surgeons developed new techniques to treat damaged tissues
PLASTIC SURGERY advanced through the work of Harold Gillies
Uses of X-rays
locate bullets, fractures inside the body → surgeons able to operate more accurately and safely
mobile x-ray units were developed and used near the frontline
→ improved diagnosis and reduced risk of unnecessary surgery
Blood Transfusions discovery
discovery of blood groups made transfusions safer and more reliable
methods for storing blood were developed, allowing transfusions away from donors
→ improved survival rates for wounded soldiers
Women in Medicine
women took on new roles in healthcare during war: nurses, doctors, ambulance drivers
VADs trained women in medical care → helped meet demand for medical staff
(equality remained limited after the war)
Improved understanding of infection control
antiseptics were used more effectively on the battlefield
THOMAS SPLINT reduced deaths from infected fractures (1917)
better organisation of casualty clearing stations
Plastic and Facial reconstructive surgery
Harold Gillies developed skin grafts and new surgical methods to rebuild damaged faces → improved survival and quality of life
Advancements
Thomas Splint reduced deaths from femur fractures from 80% to 20% (1917)
Discovery of blood groups and use of stored blood (1917)
Xrays, including mobile units
Antispetics such as Carrel Dakin solution
Plastic surgery using skin grafts
Limitations
infection remained a major cause of death
early antiseptic treatments were ineffective in heavily contaminated wounds
blood transfusions were still risky before full standardisation of blood types and storage
many advanced treatments were only available in better-equipped hospitals, not near front line
plastic surgery was complex and limited to specialists
Alexander Fleming 1928
discovered penicillin (antibiotic)
identified its antibacterial properties but was unable to mass-produce it
his findings were overlooked due to practical limitations
Howard Florey and Ernst Chain 1930s
they successfully purified penicillin
worked with US pharmaceutical companies to mass produce it
By 1944, enough penicillin was produced to treat all Allied soldiers wounded on D-Day
Impact of Antibiotics
penicillin reduced deaths from bacterial infections dramatically
survival rates for wounded soldiers increased in WWII
made surgery safer by preventing post infections
Impact of WWII
accelerated medical advances due to urgent need and government investment
Penicillin mass production (1943-44)
Blood transfusion systems improved: blood banks, plasma storage
Mobile medical units, field hospitals
Women in Medicine during WWII
worked as doctors, nurses, specialists in organisations such as EMS
contributed to research and hospital care
→ proved their capability in medicine yet still faced barriers
Beveridge Report
proposed a system to tackle poverty, disease, and unemployment
recommended a state-funded healthcare system → laid foundation for NHS in 1948
Creation of NHS 1948 by Aneurin Bevan
provided free healthcare for all citizens
hospitals, doctors, medical services brought under government control
funded through taxation, ensuring access regardless of income
Importance of NHS for public health
improved access to doctors, treatments for the whole population
reduced inequality in healthcare between rich and poor
vaccinations and regular check-ups became more widespread
→ long-term system for maintaining national health
