What is known
″ HIA: combination of
procedures, methods and
tools by which a policy may
be judged as to its potential
health effects on a
population, and the
distribution of these effects
within that population.
″ 1st Step: Screening policies
to identify candidates for
applying HIA, generally a
qualitative process.
Aim
″ Show how multivariate statistical
methods such as cluster analysis
may helps us screen policies for HIA
in a quick and reliable way, by
grouping, shortlisting policies and
prioritizing scenarios
Data
″ Ratings (1-Very low to 10-Very high) of
76 policies proposed by the Technical
Group planning the Portuguese
hospital reform regarding Potential
impact, Ease of implementation and
Implementation costs (2011 public
health experts panel)

″ 7 groups of policies were identified with hierarchical cluster analysis
″ K-means cluster analysis, Principal Component Analysis (PCA) and
Multiple Correspondence Analysis (MCA) were used as complementary
multivariate methods, to validate results and help its interpretation

″ Group C1 lead all possible scenarios when re-ranking policies according
to different priority criteria: group of most obvious candidates for HIA,
policies linking hospital and primary care services

What this Study Adds
″ Quantification and multivariate statistical methodologies lead to evidence-
based screening results easy to grasp by public health experts,
epidemiologists and decision-makers;
″ Applying hierarchical cluster analysis helps choose among different scenarios
when screening policies for HIA;
″ This methodology is applicable in other forms of impact assessments, other
countries, and may integrate stakeholders’ and public’ concerns into the
decision-making process.
