Health promotion and primary prevention
What are the levels of Prevention? Give examples
Primary prevention
Prevention before it occurs by promoting and maintaining good health.
E.g. interventions to address wider health determinants (poverty, housing, eduction, employment). Reduce risk factors (exercise, quit smoking). Immunisation
Secondary prevention
Early Dx & Rx of disease before onset of Sx - to reduce the impact of a disease
E.g. Screening (breast Ca), care pathways, Rx like diet or exercise to reduce risk
Tertiary prevention
Optimal Rx of established condition to soften the impact and improve QOL.
E.g. limit disease progression, rehabilitation, support groups
Quaternary prevention
Avoid over medicalisation - protect from unnecessary intervention / medical harm
Define health as “ absense of disease”, “well being”, and as “resource”.
Absence of disease - medical model of health
Well being - health seen as complete physical, mental and social wellbeing
A resource - Health is resource of everyday life, benefits social and personal factors not just physical and mental health
What factors determine health ?
Income
Education
Employment
Housing
Social connection
Environment
Commercial influences
Healthcare
Doctors treat disease while health promotions addresses the conditions that create diseases
Define promotion
The process of enabling people to increase control over, and improve their health (Ottawa charter)
The combination of educational and environmental supports for actions and conditions of living conducive to health (Green L, Kreuter M 1990)
Give examples of health promotions
• Vaccination programmes
• Diabetes Prevention Programme
• Smoking cessation
Community
• Active travel schemes
• Green social prescribing
Policy
• Soft drinks levy
• Tobacco legislation
Digital
• Online safety regulations
• Digital literacy programmes
What are the 3 methods to promotion ?
Bio Medical (clinicians)- Absence of disease, promoting models
Rx BP, assess risk factors, GP review
Behavioural (individual)- Health as energy, functional ability of an individual, disease-preventing lifestyles.
salt reduction, smoking cessation, weight management
Socio-environmental (local athority / Gov)- Connected to one’s family/friends/community, being in control, ability to carry out tasks that are important or have meaning.
living condition, active travel, work/school health policies
What are the 2 methods of targeting a population when it comes to promotion?
High-risk approach
identify few who are at high risk & target intervention on them > large benefit to those at high risk. E.g. CVD screening in primary care
Cons: leaves the root cause untouched > small impact on total disese burden
Population approach
target whole population for intervention - modify their risk > great population benefit. E.g get everyone to reduce salt to better their BP
Cons: although huge benefit to community, it offers little benefit to each individual
Describe the key features of prevention vs promotion
PREVENTION
PROMOTION
Comes from Medical model of thinking
Comes from Positive holistic model
Focus on specific disease
General, and benefits are wider
Targeted at risk group
Whole population approach
Most interventions prevent disease and promote health
Health promotion largely aligns with primary prevention, but also influences secondary and tertiary prevention.
What are the behaviour change theories?
BCT help to understand why people behave the way they do.
Individual level theories
Interpersonal level theory
Community level theories
Note: learn about behaviour change wheel (COM-B model)
Capability - do they know how?
Opportunity - can they?
Motivation - Do they want to?
What does the intervention ladder offer and what are they?
It demonstrate the strategies that are available.
Eliminate choice - isolation of patients with infectious diseases.
Restrict choice - remove unhealthy ingredients from food.
Guide choice through disincentives - taxes on cigarettes
Guide choices through incentives - tax breaks for buying bikes used to travel to work.
Guide choices through changing the default policy: instead of chips provide another healthy option
Enable choice: enable individuals to change their behaviours > participation in stop smoking programmes.
Provide information to public - encourage to walk more.
Do nothing or simply monitor the current situation.
Name the health promotion strategies
Health communication - to positively influence e.g ads, billboards, leaflets, food labelling
Health education - aim to improve knowledge / skills beneficial to health to patient / community. E.g how to manage asthma / DM, 1:1 sessions
Self-help / mutual aid - people with common experiences support eatch other e.g. alcoholic anonymous, CVD rehabs
Organisational change - create supporting evironment to make healthy choices e.g no smoking /healthy eating policy
Community development / mobilisation - petitions by locals
Policy / legislation - enforced by law e.g smoke free zones, seat belt, sugar tax
Given an example of a disease where medical vs social interventions can be used.
Tuberculosis
Social interventions (improved housing, hygiene, wealth) allowed for a drastic reduction in the prevalence of TB
Medical interventions (antibiotics and immunization) allowed for further reductions in prevalence.
What are the roles of a doctor in health promotion?
Should consider health promotion in all consultations.
Ask about lifestyle (smoking / exercise)
Offer advice and appropriate referral, e.g., dietician and smoking cessation service
Empower patients to manage chronic disease and offer appropriate support.
Goal setting, review, monitor
Undertake public health research.
Contribute to national reports.
Advocacy by professional bodies/coalitions (have huge influence in governments - help change policies)
define screening, interpret the sensitivity / specificy & predictive values of a screening test
Differentiate between screening programmes & diagnostic test
Potential harms of screening
Describe the criteria for assessing the appropriateness of implementing a population screening programme
Explain “ volunteer bias”, “lead time bias” and length time bias
What is screening?
It is a process of identifying apparently healthy people who may be at increased risk of disease / condition
They can be offered information, further tests, Rx to reduce their risk +/- any complications arising from the disease
Leads to early detection of - disease (Cancer), pre-cursor to disease or susceptibility to disease (CVD) in people with no signs or Sx of the disease
Can be done by - questionnaire (score), exam (BP check), lab (smear test) or imaging (mammography)
What does sensitivity and specificity means when applying screening test results ?
Sensitivity = rate of true +ves (TP) - proportion of diseased people correctly identified as diseased (i.e how good is the test at picking up the disease) > few false -ve
Sensitivity = a/(a+c)
More useful when the test result is -ve > ideal for screening where missing a disease > serious consequences e.g transfusing HIV +ve blood
Specificity = rate of true -ves (TN) - proportion of healthy people identified as healthy. (i.e how good the test is at R/O people without the condition) > few false +ve
Specificity = d/(b+d)
Most useful when test result is +ve > less likely to label healthy person as diseased = ideal for screening where false Dx can be serious e.g. TOP as Dx Down’s
In summary:
Higher sensitivity is good at ruling people out through an increasing rate of true positives
Higher specificity is good at ruling people in through an increasing rate of true negatives
What is the purpose of predictive values and how is it calculated?
Predictive values can be calculate to figure out how positive or negative a result actually is. i.e:
If you test positive, how likely is it that you really have the disease? -> PPV = a/(a+b)
If you test negative, how likely is it that you really don't have the disease? -> NPV = d/(c+d)
What is prevalence and how is it calculated?
Prevalence = how common or rare the disease is in the group being tested?
Single best factor which impacts the PPV / NPV
Prevalence of a disease = (a+c) / (a+b+c+d)
A new test is being promoted to screen for HIV. The test has sensitivity of 99% (TPs) and specificity of 99% (TNs).
Suppose the test is used on 100,000 people, where the prevalence of HIV is 1 in 1000:
Calculate the values of True +ve (a), false -ve (c), false +ve (b) and true -ve (d)
To calculate ‘a’ - work out no of true +ve
Prevalence is 1 in 1000 > in a population of 100k, 100 pts with HIV. Out of these, the test wil identify 99% (sensitivity) as having the disease -> so ‘a’ = 99
Using this, can calculate ‘c’ - false -ve = 100-99 = 1
This leaves population of 99,900 without disease (100k-100
To calculate ‘d’ -work out true negative
There are 99,900 people without HIV - of these the test will correctly identify 99% (specificity) —> 99,900 x 0.99 = 98,901 TNs = ‘d’
Using this, calculate ‘b’ - false +ve
Test would have flagged 1% as +ve falsly > 99,900 (without the disease) - 98,901 (correctly identified as without disease) = 999 = FPs = ‘b’
Using these, +ve predictive value (PPV) and -ve predictive value (NPV) can be calculated
In this E.g. the +ve PV of 9.02% = of those tested +ve, only 9.02% actually had the disease, the rest are false +ve
The -ve PV of 99.99% means if you tested -ve, its 99% reassuring that you dont have the disese.
What is the difference between screening programme and diagnostic testing?
Screening programmes:
Comprehensive disease control activity based on the identification & Rx of persons with either unrecognised disease or unrecognised risk factor for disease
The benefit must outweights the risk caused by screening
Screening test:
Specific technology (survey questionnaire, physical observation or measurement, laboratory test, radiological procedure, etc.) used to help identify persons with unrecognized disease or unrecognized risk factors for disease.
Discuss the potential harms of a screening programme?
Despite potential benefits such as early Dx, less invasive Rx, better outcomes & reduced mortality, there are potential harms:
True +ve > being labelled
False -ve > false reassurance, disregard Sx, delayed intervention
False +ve > cost of futher test, anxiety, fear of future screening
True -ve > cost & risks of screening programme
Who overseas the screening programmes in the UK, give examples of existing screening?
Screening in UK employes national screening committee that
Addvises ministers using latest research evidence, MDT expert groups & patient/service users.
Assess proposed new screening against the crieteria to ensure it will do more good than harm at resonable cost
Examples of screening programmes:
AAA, bowel cancer, cervical screening, newborn / preg screening, breast and diabetic eye
Describe the criteria used by NSC for assessing the appropriateness of implementing a population screening programme
-> Natural Hx of disease - conditions worth screening only if the natural Hx of disease is understood. To do this, need:
Pre-clinical detectable period, tests that can be applied and treatment that will alter outcome
-> Criteria used by NSC (pic)
Explain what is meant by “volunteer bias”, "lead time bias" and
"length time bias
Biases can occur when comparing outcomes (e.g survival time) of patients identified by screening to those identified clinically, bias can occur:
-> Volunteer bias
Decision to attend screening is often influenced by individual’s health awreness.
?more healthy people attend screening - important to consider how participants recruited for screening
-> Lead time bias
Amount of time gained by earlier detection of a cancer by screening than by later detection with Sx -> apparent increase survival.
To minimise this bias, mortality rate should be Ax rather than survival
Early Dx doesnt necessarily mean longer life
-> Length time bias
Those with long pre-clinical phase more likely to be detected by screening + have better progosis (less aggressive disease)
Define tertiary prevention
Describe some examples
Integrate prevention concepts
Reducing impact of disease (once established) in symptomatic patients. Main goals are:
Provision of Rx and rehab to minimise progression & complication e.g # prevention in osteoporosis
Who are the target audience of a tertiary prevention?
Targets patients with establised (chronic) disease
Intervention starts after acute pahse is over
Focused on specific, often small group of people living with the illness
Focus is to improve function & prevent further disabiity / complications & disease progression
There is lack of clear boundaries:
Ongoing process > long term interventions > No clear end point
In most areas, there is limited evidences & poor consensus = need to be adaptive, MDT
What are the tertiary prevention strategies / method?
Can be carried out either via rehab programme or chronic disease management.
Typically complex interventions - multifaceted at multiple levels that work together
Possible strategies:
Medical Rx + routine reviews
E.g. DM (monitor BMs / U+E / eye), cancer survivor (monitor for recurrence / Rx SE), chronic pain, osteoporosis (bisphophonates)
Rehabilitation (PT/OT)
E.g post CVD, CVA (speech / mobility / motor skills), pulmonary (breathing / QOL) and amputation (for functional independence)
Patient education & self-management - mobile apps / support groups
Input comes from MDT
Doctor, specialist nurse, OT, PT, dietician, pharmacist, social worker, SALT, psychologist
Give an example of primary, secondary & teriary prevention measures stroke
Primary:
Health promotion around smoking, alcohol, exercise, healthy weight, diet.
Rx CVD risks - HTN, high cholesterol, obesity, DM
Secondary:
Early recognition using FAST (Face, Arms, Speech, Time).
Management of TIA via medications and surgeries. E.g. anti-platelents, statin, anti-HTN, carotid endarterectomy
Tertiary
Stroke rehab to regain lost functions and improve QOL.
MDT for holistic approach, Long term process with specialist stroke units, tailored to patient’s need
Evidence based - stroke rehab reduces disability & mortality
E.g SALT (speech,swallowing), PT (mobility, balance, coordination), OT (care needs, ADL), cognitive therapy (momory, attention), psychological counselling (depression, anxiety)
Give example of tobacco control measures
Tobacco is the leading cause of illness, disability & death
Has significant cost impact, accounts for 25% of cancers
High prevalence in - men, unemployed, in deprived areas, gay / lesbian / bisexual, lack of qualifications
Control measures
Public awareness campaigns, health warning on packaging, tobacco duty & tax
Age restrictions, ban open display, ban public smokin
Offer pharmacotherapy & behaviour support
End of life care
What is palliative care?
It is about caring for people in incurable illness to relieve their suffering & supporting them through difficult time.
WHO - An approach that improves QOL of patients & families facing life threatening illness through prevention & relief by early identification, assessment & Rx of pain, physical, psychosocial & spiritual needs.
Can be in conjunction with other therapies to prolong life e.g chemo or RT
Supportive palliative care
Is about living as well as dying - aim is not to prolong life or shorten it, but to improve QOL for the time left. Can complement the Rx already being given.
As the population is increasing & more people are living longer > more people surviving iwth chronic conditions = more people will need palliative as time progresses.
What is end of life care?
Enables the supportive and palliative care needs of both patient and family to be identified and met throughout the last phase of life and into bereavement.
Aim to help somone nearing EOL to be comfortable.
Supportive care = management & prevention of adverse effects caused by cancer & its Rx. - including physical & psychosocial support. e.g Macmillian
It is not same as palliative care - it is a form of palliative care to help those in their final months / yr of their life.
What does Holistic approach means?
There should be a holistic approach to palliative care where we look at the patient’s:
Physical symptoms and needs.
Psychological well being.
Social factors and situations.
Spiritual beliefs and needs.
Total pain - one issue affecting / causing issues in other areas.
What are the common trajectories why someone may need palliative / EOL care?
Frailty / co-morbidities / dementia
Organ failure
Cancer
sudden unexpected death
-> Most people now a days die in the hospital, next is their own home, then NH & few in hospice.
What are the current NHS EOL policy?
NHS EOL policy 2008
Covers all conditions & all settings.
Aim to bring QOL to those approaching EOL, enchance choice in life and invest in palliative.
Liverpool care pathway 2013
Removed due to lack of communications with family.
Later replaced with individual EOL care plan - patient should be placed on EOL by senior cons with patient & health care team.
New national framework 2021-2026
Each patients should be seen as individual & should have tailored EOL care specific to them. Should be well informed by HCPs on what their next Rx is.
To maximise comfort & welbeing.
What is advance care plan and what are the 3 elements it inculdes?
How people prepare for EOL care, and includes 3 elements.
What do you want to happen (Advance statement): Statements of wishes and preferences, not legally binding.
What do you NOT want to happen (Advance decision): Decision to refuse treatment (legally binding)
Who will speak for you if you lack capacity: Assigning a proxy or lasting power of attorney.
Introduction to Health Economics 70126802
1. Define the concepts of scarcity and opportunity cost
2. To recognise health care as an economic good
3. Define and distinguish between the concepts of technical
efficiency and allocative efficiency
4. Define economic evaluation
Key take home from this lecture:
We can think of health care as being an economic good.
No health care system in the World has ever achieved levels of spending sufficient to meet all the wants of all its clients.
Health economics seeks to inform the allocation of scarce resources. It is NOT about choosing the cheapest option. It is about directing resources to treatments which bring about the greatest health improvement across the population.
What is scarcity and economics?
Scaricity is the heart of all economics - how to use limited resources:
Resources are limited or constrained. (finite resources)
The potential uses of these resources are unbounded. (infinite wants)
-> As a society, we have finite resources but infinite wants - so need to be careful with how we use the limited resources.
-> Economics is therefore study of how decisions are made in the context of sarcity
Quantify the costs & benefits of healthcare interventions
-> Economic goods = any good or service that is scarce relative to out wants for it
Define Opportunity cost - give example
Value of the consequences forgone by choosing to depoly resources in one way rather than in their best alternative use
Given in a fixed budget in NHS, increasing production in one speciality > diverting resources away from other
E.g If hospital have 1m for budget and it choose to spend it on new lab, the opportunity cost would have been extra nurse hire / other outreach programme that it can no longer fund
Define positive and normative economics
Positive economics
An objective, fact-based stream of economics, focusing on data analysis and the use of facts and figures
Makes objective statements that can be proven / disproven by researching the data
“how does life expectancy in UK compared to Europe?”
Normatice economics
Value based, sujective stream of economics which considers personal opinons & values to make decision on what is the right thing to do.
“UK gov should increase spending on healthcare”
What is priority setting / Rationning in healthcare?
Most rationing is by price in daily life
When healthcare is free, there need to be other form of rationing or priority setting
Prioritise treatment which are most cost-effective > gives greatest amount of benefit / outcome for investment
If we accept that scarcity and opportunity costs are real, then how do we make the most of the resources we actually have?
Efficiency vs Equity
Efficiency:
The allocation of scarce resources in a way that best helps us achieve our goals. Important in both +ve & normative economics
Technical efficiency = Producing output in best way possible, without wasting the limited resources i.e Optimise process for a given output
Allocation efficiency =Producing output that best satisfy the consumer’s wants/needs
In other words, TE looks at doing things right, while AE looks at doing the right thing overall
Equity
Relate more on normatic economics & is synonymous with fairness & social justice.
Most equitable outcome may not be most efficient
What is the use of Economic evaluation and what are the methods used ?
Decision in NHS is made ideally based on evidence - which need to be generated -> economic evaluation
Its the comparative analysis of alternative courses of action in terms of both cost & consequences - comparing standard Rx to new intervention
Cost benefit analysis = monetary value of health improvement must be assessed
Cost effective analysis = beneficial in techinical efficiency - cost expressed in units and outcome in numbers. E.g no of asthma attacks prevented
Cost utility analysis = beneficial in allocative efficiency - cost expressed in units and outcome expressed as QOL yrs
Methods of economic evaluation:
Above methods usually focuses on efficiency - but don’t address equity
How is Incremental cost effectiveness ratio calculated ?
ICER = difference in cost / difference in outcome
E.g Zopiclone costs £1.75 > 6hrs sleep. Newer drug cost £2 > 7 hrs sleep
Cost difference = £2 -£1.75 = 0.25p
Outcome difference = 7-6 = 1hr
Henve ICER = 0.25/hr = costs 25p to get extra hr of sleep
If the ratio is low, the decision is made to choose new, better Rx as cost is not high.
Measurement of Outcomes and Costs in Economic Analysis
Understand what outcomes and costs can be collected and measured within a health economic analysis
Understand the rationale for their inclusion
Recognise the limitations of different measures of costs and outcomes
What are the key objectives of economic analysis in heathcare?
Promoting the efficient use of heath care resources
Ensuring that maximum total benefit is derived fom the limited resources available
Explore this case study in terms of clinical outcomes and decision making
Economic evaluation - need to identify relevant cost & outcome
Clinical outomes - measured in natural units
Proxy outcome - e.g cancer detected / change in Ch level
Condition specific measures - e.g Questionnaire for pain
Generic measures - Yrs of life gained
Advantages = measured as part of clinical study, easy to understand, transparent to clinicians
Limitations = lack of comparability across different disease, what if more than one outcome?
In the HTN case study above:
Shorterm outcome = BP reduction
Longterm outcome = No of stroke/MIs, No of CVD & death
Which durg to fund A or A?
Drug A - low cost, moderate impact on life expectancy/QOL
Drug B - high cost, large impact on LE & QOL
QALYS = quality adjusted life yrs
Combines length & QOL into one unit -> cost-utility analysis
QOL measured - 1 (perfect health) to 0 (equivalent to death)
QALY = Σ (length of life) x (QoL)
Interpret and Calculate the QALYs using this graph
X axis = yrs of life. Y axis = value of QOL
Solid line = prognosis without treatmnet
Dashed line = prognosis with treatment
A = area where prognosis with Rx has additional QALYs
B = area where no Rx gives more QALYs
White area + B = QALYs without treatment
Calculating QALYs from graph above:
Prognosis without treatment: (0.7x1) + (0.6x2) + (0.4x1) + (0.3x1) + (0.2x1) + (0.1x2) = 3.0
Prognosis with treatment: (0.5x1) + (0.6x1) + (0.7x1) + (0.8x1) + (0.9x4) = 6.2
Total gain in QALYs: 6.2 – 3.0 = 3.2
What are the 5 dimensions of Euro-QoL EQ-5D-5L questionnaire?
A questionnaire with predetermined weights, with each dimension having 5 levels:
The 5 dimentions:
Mobility, self-care, usual activities, pain/discomfort and anxiety/depression
Outcomes of Euro-QoL 5L Health States
Health state is how patient complete these questionnaire & each answers is assigned a number (tariff)
Tariff = QOL value (lower QOL = lower tariff) 1= no problem
E.g QOL with Rx > 11111 (value 1.0) for 10 yrs. vs QOL without Rx >21212 (value 0.743) for 10 yrs
QALYS = QALYs with Rx - without Rx for 10 yrs
(1.0x10) - (0.743x10) = 2.57 QALYs gained
Where can you gather information to obtain data on QOL (utility) to calculate QALYs?
1. EQ-5D questionnaire.
2. Value judgement (e.g., by asking clinical experts)
3. Direct measurement of QOL from patients using health state description.
4. Life tables & literature (long term), death recoded in study (short term)
5. Published values in literature.
What are the advantages and disadvantages of using QALYs?
Advantages:
Takes into account impact on quality & QOL
Common unit of measure that can be used across disease areas
Convenient tool for measurement e.g EQ-5D
Disadvantages:
Places no emphasis on who gains the QALY - child vs old patient > not addressing equity
Whose value we take ?patient / carer / clinican
Insensitivity of questionnaire, EOL Rx
Discrimination, may not take broader patient benefit into consideration, or family/carer benefit into consideration.
List some broader outcomes that are not always captured by QALYs
Patient benefits not captured by QALYs:
Control / empowerment - pt feel in control of their condition due to intervention
Reassurance - given by screening test
Knowledge
Satisfaction with care
Capability - e.g independence
Family / carer QOL
Give examples of direct vs indirect costs of health and social services
Health and social care costs:
Intervention / related medications
Primary care cost - GP / nurse visit
Secondary care cost - A&E, OP, IP, surgery, test, Ix
Social services - NH, POC, home adaptations
Patient / carer incurred cost:
Cost of time & transport for health visits
OTC meds / appliances
Paid carers, informal carer time
Indirect costs:
cost due to lost production = unable to work due to diability, time off work due to illness - these dont apply to UK analysis but are collected for reference
How is cost estimation is done for patients?
Measurement of quantities of resources from case notes / data system / patient questionnaire
Assigment of unit cost or price to those resources
Equity in healthcare: - why it matters in economic evaluation
Define quity, types & distinguish from equality
Explain importance of equity in economic evaluation
Describe trade-offs between efficiency & equity in healthcare
Identify methods used to integrate equity in economic evaluation
Apply concepts to motivating economic exaples
Define Equity and why is it important to consider ?
-> Existing Economic evaluation methods such as cost benefit / cost effective & cost utility analysis focus on efficiency but don’t adress equity.
-> The standard cost effecitve analysis (CEA) methods don’t capture the health impacts of Equity.
-> Equity = fairness in the distribution and allocation of health across society.
Equality on the other hand is giving equal access.
Efficiency = greatest good for greatest number
-> Health Equity: addresses differences in population health that can be traced to unequal economic & social conditions
-> Health inequalities / disparities = Preventable health differences between groups of people - this can affect how frequently a disease affects a group & how many get sick
What are the different types of Equity?
Horizontal equity
Equal treatment / use of NHS resources of people who are in equal need > individuals with same need for care have same use of healthcare.
If 2 people need urgent lapchole, horizontal equity states both should get equal access to this service
Varitical Equity
Unequal treatment / use of NHS resources of people who are unequal in needs > individuals with different levels if illness have different level of use
pt with complex illness would get more resources allocated compared to one with minor illness
Give examples of where Cost effective analysis (CEA) is not enough
Comparing extra cost or new Rx against the extra health outcomes, CEA might not be enough because:
Considering equity in economic evaluation in itself impose a cost
Impact of policy decisions in distribution of costs & benefits on variables like gender, age, location, severeity, status
Population wide public health interventions not adequately accounted for
What are the approaches to Equity in Economic evaluation ?
Subgroup analysis of groups / patients:
Do a CEA for particular Rx and consider the population, then repeat the analysis using subgroups experiencing inequality to assess the impact this has
Equity weighting
Attaching different weights to health outcomes > value same health gain differently depends on who receives it (greater value for disadvantaged)
Wight can be based on views of pupulation / decision makers / clinicians
Reflects to what extend society sacrifices health gains for equity
Other tools for promoting equity
Ensure universal health coverage
Target subsidies - e.g free for low income groups
Prioritisation framework - e.g NICE social judgement in UK
What does NICE framework says about Equity consideration?
Offers a framework for incorporating social & ethical values for funding interventions above the threshold
Recognises that society & patients have valid claims to resources over and above the cost-effectiveness evidence
Health technology assessment (HTAs) - Cost effectiveness threshold by NICE is £20-30K
If cost per QALY of new Rx is within this range, it is considered acceptable use of taxpayers money for the benefit it gives
Some exceptions to this are - EOL care, ultra-orphan drugs to Rx rare conditions and cancer drung funds
-> NICE primarily centered on maximising health gains but it allows for exceptions based on fairness, justice & compassion.
NICE and national level decision making
What is Rationing?
Ways in which healthcare interventions are restricted in order to control spending or increase efficiency
Rationing is a response to situation where demand exceeds supply for healthcare
Why does Rationing happens?
Demography - change in population demographics
People have high life expectancy / larger proportion of elderly population
Pattern of disease - rates of different disease rise or fall in the population > resources managed to match this e.g Covid
Medical technology - As tech improves, less priority may be needed on certain condition / disease to invest in newest intervention which may be more expensive
Staffing & service organisation - each speciality has sub-specialities > raise cost > minimum staff > create pressure
Expectation & culture - as population ageing, expectations are changing
How does rationing take place / operate?
Rationing can be done either Explicitly or implicitly - most healthcare systems use mix of both to manage resources
-> Implicit rationing
Not acknowledged, less visible & based on hidden allocations.
Involves decisions made by managers / professionals / front line staff as they allocate resources within fixed budget
E.g Delays, weighting list, dilution (less time/pt) and denial of Rx based on eligibility
E.g Nuse or doctor prioritse task / time spend with patient depending on staffing / pressure
-> Explicit rationning
uses public, formal & clear set of rules to determine who receives resources and who don’t.
Political methods = discussion & consensus via surveys, voting & conferences
Technical methods = cost effectiveness evaluation
E.g Triage system in A&E uses formal crieteria to priotise patients based on severity of conditions
What is the purpose of NICE and what does it hope to tackle?
NICE is the independent organisation responsible for providing national guidance on the promotion of good health and the prevention and treatment of ill health.
-> Hopes to tackle
underachievement of health services
Unacceptable variation in care
Poor uptake of effective practice
Excessive use of inappropriate treatments
Continued use of ineffective treatments.
What explicit criteria used by NICE for decision making?
ICER = incremental cost-effectiveness ration
ICER <£25K/QALY = usually accepted unless poor evidence
ICER £25-35/QALY = judgement considered:
?health-related QOL was properly measured, innovating nature of technology & non health objectives
ICER >£35K/QALY = usually rejected unless there is strong arguments with respect to above criteria.
EOL has additional guidance
Justice and Rationing
- Outline some common models of distributive justice and provide some critiques of these
- Identify and discuss the models mentioned in the NHS constitution
- Discuss the necessity for rationing and outline some potential approaches
- Define an ‘orphan drug’ and present ethical arguments for and against investment in unprofitable pharmaceuticals
Explain the founding purpose and core principles of the NHS. How do these reflect a humanist approach?
The NHS was founded in 1948 to address social injustice by providing healthcare for everyone.
Its principles include universal access, care free at the point of delivery, central funding, comprehensive services, high quality and equity.
Why does healthcare require decisions about distributing resources? Briefly explain the main models of distributive justice.
Healthcare resources are limited, while demand is high - hence models of distributive justice employed:.
Egalitarianism - favours equal shares (everyone get same)
Meritocracy - rewards contribution (everyone gets according their contribution)
Socialism - allocates according to need / ability
Libertarianism - prioritises individual choice
Rawlsian fairness asks what rules people would choose without knowing their social position.
Describe the egalitarian model of distributive justice and how it might guide healthcare allocation. Discuss its limitations.
Egalitarianism supports equal rights and access to care.
Resources should be allocated equally amongst all members of the society
A lottery allocation may be used when a resource is scarce.
However, equal allocation may overlook differences in clinical need & do not take account of different needs. e.g organ need or congenital issues
Explain meritocratic distribution and its possible application to healthcare. What difficulties arise when deciding who deserves priority?
Meritocracy allocates rewards according to merit or contribution. = Those who contribute more, receives more
In healthcare, this could favour people considered more deserving. > prosocial behaviours.
Advocates for people e.g parents, veterans, tax payers, business owners & volunteers
But merit can reflect unearned advantages, and responsibility for health-related behaviour is often difficult to judge. e.g private education can be purchased, business owners contribute my exploiting their workers?
Describe the socialist model of distributive justice and how it is reflected in the NHS and wider society. Discuss potential criticisms.
Socialism asks people to contribute according to their ability and receive according to their need.
The NHS reflects this by pooling public funds to provide care based on clinical need (where most needed). - those who benefited most should contribute most.
Critics point to bureaucracy and possible effects on incentives. - promotes helplessness & dependence on state
Explain the libertarian approach to healthcare and compare its assumptions with those of a publicly funded health service.
Libertarianism prioritises individual choice (autonomy) and responsibility, with a limited role for the state (gov).
People would decide how much to spend on healthcare. e.g health insurance / pay for procedure you want
Critics argue this overlooks how poverty, luck and unequal resources restrict people’s choices.
Outline Rawls’s idea of fairness and the “veil of ignorance.” How might this thought experiment guide decisions about healthcare and social policy?
The veil of ignorance asks people to make social rules without knowing their own health, wealth or status.
This encourages rules that people could accept from any position, including when they are vulnerable or unwell.
The role of society is to ensure that privileges, burdens, and resources are distributed fairly.
Critics - encourages culture of victimhood - e.g if people are allocated based on their disadvantages, they will exagerate their degree of disadvantage.
Also there is no reward for contributing > discourages pro-social behaviour
Distinguish equality from equity in healthcare. Why might equal treatment fail to meet people’s different needs?
Equality gives everyone the same access or treatment.
Equity adapts support to different needs so people have a fairer opportunity to benefit.
Describe the principles that should guide the distribution of NHS services. How do clinical need, patient-centred care and value for taxpayers relate to one another?
NHS services aim to be comprehensive, patient-centred, high quality and available to all according to clinical need.
Decisions must also use public funds responsibly and remain accountable. - best value for taxpayer’s money
Accountable to the public, communities, and patients that it serves.
Explain why the NHS has to ration healthcare. Include relevant demographic, clinical and financial pressures.
Demand rises due to factors such as an ageing population, multimorbidity, increased consumption of resources and costly treatments.
Because funding and resources are limited, choices must be made about which services and treatments to provide.
Role of NICE - decides which novel Rx offers value for money for NHS, calculates cost effectiveness using QALY (how much life is gained)
Discuss how an ICU bed might be allocated when demand exceeds supply. Explain the roles of first-come-first-served allocation, likelihood of recovery and efficient use of the bed.
First-come-first-served gives patients an equal chance of an ICU bed (egalitarian distribution).
But this can block another person who is in greater need from accessing the bed
So when bed is scarce (e.g pandemic), priority is given based on clinical need / better survival rate regardless of who came 1st (utelitarian approach)
Clinicians may also consider likelihood of recovery, duration of admission, utility of resouce, how quickly a bed may become available and whether transfer is possible.
During a public health emergency, should a patient with a better chance of survival take priority over someone who arrived first? Discuss the ethical arguments and concerns raised by this approach.
Prioritising a patient with a better chance of survival may increase the chance of saving a life.
However, changing priority after treatment begins can cause severe distress, and criteria such as age raise concerns about fairness and discrimination.
Explain prioritarian reasoning in healthcare. How might it support giving priority to younger patients, and what ethical concerns could this raise?
Prioritarianism gives extra weight to helping those who are worse off.
It may favour younger patients because they have had less opportunity to benefit from life.
However, age-based priority can disadvantage older people and needs careful justification.
What is meant by “double jeopardy” for people with rare diseases? Explain how reliance on cost-effectiveness or QALYs could disadvantage them.
“Double jeopardy” describes how people with rare diseases may have serious health needs and fewer treatment options.
Cost-effectiveness measures may disadvantage them because treatments benefit smaller numbers of people.
Disadvantaged people find themselves disadvantaged x2
Describe measures that could improve support for people with rare diseases. Include the role and challenges of orphan drugs.
Orphan drugs - drugs to treat rare diseases and may need government support because they are not commercially viable to develop.
They can still be very expensive, making fair access difficult.
Pure utilitarian approach would not justify the invest,ent to save such small no of peple - because they focus on greatest good to larger no of people.
UK strategey for Rare diseases:
Improve recognition - training clinicians
Internationally co-ordinated research
Review of how cost-effectiveness is considered in rare diseases
Improve access to international experts & strategic funding of research in rare diseases.
