Lec 3 Flashcards
what does a research study try to do
tries to answer a question
what is the one aim of a research study
to underpin the understanding of clinical research methods relevant to the practising optometrist (wants us to have that knowledge)
what is the aim of experiments in clinical research
proving or contradicting a hypothesis with data (to prove something is best clinical practice)
what are experiments in clinical research interested in
an outcome (dependent) which may be influenced by an attribute (independent)
what did john snow do a experiment in
the cholera epidemic in london - the link between cholera and drinking water
what year did john snow carry out his experiment
1854
what is an epidemiology
the study of causes and risk factors of a certain disease, or someone getting the disease
what does a epidemiology prove
if a certain treatment will work
what is the purpose of evidence based medicine
to apply the best available evidence gained from the scientific method to medical decision making
(about collecting information and data to support a hypothesis)
what does evidence based medicine (EBM) seek to assess
the quality of evidence of the risks and benefits of treatments (including lack of treatment)
which two bodies is EBM used by
NHS and NICE
what does NICE do
it publishes clinical appraisals of whether particular treatments should be considered ‘worthwhile’ by the NHS
it decides what search evidence to be used in the clinical domain and decides what healthcare service is affordable, so they decide on the costs and benefits of treatments
why is EBM important for optometrists too
as we are primary clinical care providers e.g. with the OCT, research study was done to decide if its a good tool to use e.g. in AMD etc
what two types of research is EBM found in
primary and secondary
where does primary research come from
the researchers themselves written in journal articles/research papers
