Unformatted text preview: t, the statistical signiﬁcance of the results
is often less important than the practical interpretation or
the visual impact of differences in a graphic presentation.
For example, data from these initiatives are often presented
as run charts, indicating a rate or score trend over time,
with clinically important changes illustrated as crossing lines Process-based measures of health care quality representing acceptable upper or lower bounds rather than
statistically signiﬁcant differences.
Purchasers and patients
If the audience for the measures is purchasers or patients and
the intent to provide information for health care purchasing
decisions, summary or aggregated data are more helpful.
These groups may prefer a comprehensive measure that is
presented in a way that is understandable to patients, beneﬁt
managers, and enrollees. For these groups, it is important
that the process measure is already demonstrated to have a
strong link to outcome, as they do not perceive it as their
role to conduct clinical studies establishing these links. It is
more important for these audiences that patients and enrollees
rather than providers believe the measure evaluates an important domain of quality. Statistical signiﬁcance among
groups becomes increasingly important; patients and enrollees
want to know ‘which is better’. Despite this, further research
is needed to design and present quality measures that enable
patients to make informed decisions regarding quality of care.
Accreditation and regulatory to develop and maintain process measures have made them
more feasible. To be valid, process measures should have
links to important outcomes, or should at least be determined
by consensus methods to be judged by clinical experts to be
important to patient outcomes. The past decade has brought
a greater emphasis on synthesizing the evidence basis for
how process of care affects outcomes and has made this
information more readily available to the provider community
as well as the public. In the future this will provide the
ultimate base for the development of process measures of
