Q

UCLH Pathway Programming

A

For homeless patients admitted to hospital. Involves hospital GP’s and nurses working with others to address the social determinant’s of housing, financial and social issues of patients. After its introduction, A&E attendance by supported individuals fell by 38% with a 78% reduction in bed days

Sensitivity
% of people with disease who test +ve. Screening tests should be highly sensitive
26
Specificity
% of people without disease who test -ve. Diagnostic tests should be highly spp
27
Evidence about effectiveness of screening
RCTs provides best evidence Time trends in disease incidence and outcomes – compared to countries/ regions without screening Case control studies Systematic reviews of evidence Modelling (combining a variety of evidence)
28
Common sources of bias in screening evaluation
Healthy Screening effect Length time bias Lead time bias
29
Healthy Screening effect
People who take part tend to be healthier than those who don’t
30
Lead time bias
Earlier detection makes duration of survival after diagnosis longer, even if treatment is ineffective
31
Length time bias
Disease is more likely to be detected in people with longer lasting and slowly progressive types of the disease —> have better outcomes anyways
32
Common chemical hazards
``` Arsenic Asbestos Benzene Vinyl Chloride Alpha-naphtylamine Hydrocarbons Nitrates ```
33
Which cancer site does arsenic affect
Lung
34
Which cancer site does asbestos affect
Lung
35
Which cancer site does benzene affect
Leukaemia
36
Which cancer site does vinyl-chloride affect
Liver
37
Which cancer site does alpha-napthylamine affect
Bladder
38
Which cancer site does hydrocarbons affect
Scrotum
39
Which cancer site does nitrates affect
Stomach
40
Vector for malaria
Anopheles Mosquito (female)
41
Environment needed for malaria
Needs suitable temperature and rainfall
42
IPCC main risks of climate change
Greater risk of injury, disease and death due to more intense heat waves and fires Increased risk of undernutrition resulting from diminished food production in poor regions Consequences for health of lost work capacity and reduced labour productivity in vulnerable population Increased risks of food and water-borne disease and vector-borne diseases
43
IPCC main opportunities of climate change
Modest reductions in cold-related mortality and morbidity in some areas due to fewer cold extremes Geographical shifts in food production Reduced capacity of disease-carrying vectors due to exceedance of thermal thresholds
44
What does the impact of the environment on human health depend on
Vulnerability both at the individual and society levels
45
What can heat and air pollution exacerbate
Cardiovascular, cerebrovascular and respiratory issues
46
What can cause GE and cholera
Contamination due to floods and disruption of clean water supplies and sewage treatment
47
How can climate change cause more vector-borne infectious
Changes in vector number and geographic distribution of clean water supplies and sewage treatment, after heavy rains and other environment disasters
48
How can climate change cause malnutrition
Changes in local climate that disrupt crop production
49
Xenobiotics
Exogenous chemicals in the environment that may be absorbed by the body through inhalation, ingestion, or skin contact
50
Metabolism of xenobiotics
Phase 1: Chemicals undergo hydrolysis, oxidation, or reduction Phase 2: reactions of glucuronidation, sulfation, methylation, and conjugation with glutathione (GSH). Water-soluble compounds are readily excreted
51
Air pollution

75
What does specific characteristics involve
Protected characteristics such as sex, ethnicity, religion and disability.
76
