YEAR 2 EXTRAS FROM BLOCK LEARNING OUTCOMES Flashcards
What does an evidence based decision involve?
evidence from research
clinical experience
available resources
patient preferences
why are evidence based decisions important?
as it gives us a way of dealing with uncertainty, medical knowledge is incomplete, the quanity of medical facts is ever expanding, medical knoqledge is constantly shifting, it ensures patients receive the most appropriate treatment, it improves efficiency of health care services, it reduces variations in practices etc.
outline how to carry out an evidence based decision?
- Creating an answerable PICO question
- Identifying the best evidence to answer that question
- Critically appraising the evidence for validty, impact and applicability
- Intergrating the critical appraisal with clinical expertise and patient’s unique circumstance
- Evaluating effectiveness and efficiency. Seek ways to improve
what are the 3 theories of decision making?
normative, descriptive and prescriptive
what is normative decision making?
what people should do
what is descriptive decision making?
what people do or have done
what is prescriptive decision making?
what people should and can do
what is the hypothetic-deductive model of decision making?
cue acquisition -> hypothesis formation -> cue interpretation -> Hypothesis evaluation.
in which situations would you use the hypothetic deductive model of decision making?
This model is more commonly used in less experienced individuals or for diagnostic problems that are less familiar.
what is the prospect theory of decision making?
Prospect theory assumes that losses and gains are valued differently, and thus individuals make decisions based on perceived gains instead of perceived losses.
aka loss aversion (you would rather have 25 pounds than have 50 and lose 25 even though they ahev the same outcome)
what are the 2 stages of prospect theory?
framing +editing
and evaluation
what is the framing and editing stage of prospect theory?
how you characterise your choices
what s the evaluation stage of prospect theory?
the framed prospects evaluated and the prospect with the highest value is selected.
how do evidence based decisions improve clinical care?
ensure patients recieve the most appropriate treatment
increases the efficiency of health care systems
reduces variations in practice amongst health care professionals

mortality safety of care readmissions patient experiences effectiveness of care timeliness of care QUALY morbidity
what are the benefits of using NICE guidelines?
they are evidence based
they take into account cost effectiveness as well as clinical effectiveness
theres a formal process
they aim to ensure all individuals are treated equally
what do NICE do?
produce guidelines and provide advice to clinicians about best practice. They do technology appraisals, make clinical guidelines, produce interventional procedure programmes etc
what is the Cochrane
a British international charitable organisation formed to organise medical research findings to facilitate evidence-based choices about health interventions involving health professionals, patients and policy makers.
what is a case control study?
a type of observational study in which two existing groups differing in outcome are identified and compared on the basis of some supposed causal attribute.
what is a cross-sectional study?
a type of observational study, or descriptive research, that involves analyzing information about a population at a specific point in time

preventing a disease from getting worse and minimising effects by symptoms management, palliative care etc
what are some dilemmas around health promotion?
the opportunity cost - resources are already scarce and people are dying from disease so why should we take money away from treatment
its difficult to determine whats effective and ineffective
who should be responsible for health i.e. the individual, the community, the government?
what is the prevention paradox?
a preventative measure which brings much benefit to the population offers little benefit to each participating individual
if autonomy is sacrosanct, should the right to treatment be?
should smokers be treated
i.e. smoking led to the disease, smoking limits effectiveness of surgery, poor outcome will result in more surgery, expensive when resources are limited
but…
doctors have an ethical obligation to treat on the basis of need, its a slippery slope with self harm/drunk drivers etc, lower SES smoke more than HES

outline the health belief model?
its a psychological health behaviour change model developed to explain and predict health related behaviour
percieved seriousness and percieved susceptibility affect a percieved threat
this along with percieved benefits + barriers, self-efficacy and stimulus/cues to action all affect the likelihood in engaging in health promoting behaviour
what is the high-risk prevention approach?
the objective is to target the intervention at those who are at highest risk for the disease and move them to lower risk levels
what are the pros and cons for the high-risk prevention approach?
pros - appropriate for individual so motivates patient, cost effective as not medicating those who dont need it, benefit:risk ratio good
cons - hard to find these high risk groups, limited potential as only targets a small proportion, temporary, labelling issues
what is the population prevention approach?
the objective is to reduce the burden of disease across the entire population. This should shift the curve of risk to the left
what are the pros and cons of the population prevention approach?
pros - large potential as targets everyone
cons - population paradox, poor motivation, benefit: risk ratio low, treating those who dont need it
what are some causes of antimicrobial resistance?
irrational use of antibiotics in humans/animals
