7. Health Technology Evaluation Flashcards
1
Q
what is HTA/HTE & it’s pillars
A
systematic evaluation of health tech, pertaining to it’s properties & effects/impacts
pillars = quality, safety, affordability & accessibility
2
Q
why is HTA/HTE important
A
- improve uptake of cost-effective new tech
- prevent uptake of doubtful value tech
- increasing transparency of procurement/policy
- slower uptake of tech with persistent uncertainty
3
Q
at what stage of the health technology life cycle do you perform HTA/HTE
A
- R&D
- experimental & clinical research
- general clinical use
- obsolescence & replacement
4
Q
what are some user evaluation methods
A
- system usability scale
- perceived usefulness scale
- perceived ease of use scale
5
Q
what are the 4 phases of clinical trials
A
- identify effects & appropriate doses. first time testing with humans
- identify side effects. larger group of people e.g. several hundred
- testing on larger group - several hundred thousand people
- approved for public use. effectiveness monitored in general population
6
Q
what models can be used to summarise evidence
A
- correlations
- statistical distributions
- statistical significance testing
- hypothesis testing with p values for reliability
7
Q
how do the hypotheses tests & p-values work
A
define the hypotheses e.g.
H0: there is no difference longevity between the 2 groups
H1: there is a difference in longevity between the 2 groups
set a level of significance alpha, typically 1% or 5%
p <= alpha: strong evidence against H0
p = alpha: marginal
p > alpha: weak evidence against H0
