The PARiHS system can be used to bring about a change in the
practice in the following ways
- The PARiHS system consolidates all types of evidence that
supports a change in practice.
 
- This evidence includes evidence obtained from research,
experience of the clinicians and patients, organisation's data and
local observations.
 
- This evidence is more robust as compared to mere research base
evidence to bring about a change.
 
- Such type evidence is comprehensive and an organisation will
find it easy to adapt itself to it.
 
- The PARiHs system also evaluated the 'context'.
 
- Here the word context means the organisation that is looking
for a change.
 
- This system evaluated the organisation and hopes to answer the
following questions
- Is this proposed change relevant to the organisation?
 
- Does the organisation has the capacity to adopt this
change?
 
- What are the resources needed to bring about this change?
 
 
- Answering these questions is important before implementing the
change.
 
- The PARiHS also looks into facilitation of the change.
 
- Here facilitation means, the support needed by the members of
the organisation to adopt a change.
 
- After the decision is made about adopting a new policy, certain
people will be required to bring about this change.
 
- These people can help the members of an organisation by
personally doing work or by empowering the members by educating
them with the new policy.
