I just reviewed the slides of a presentation Dr. Barbara Starfield gave at a conference this past week in Vancouver Canada. She wrote:
Patients’ health problems are not synonymous
with their diagnoses. The health problems of
people and populations are not the same as
the sum of their individual “diseases”.
Diseases:• are professionally defined entities, not
pathophysiologic “truths”
• have variable manifestations, pathways of
genesis, and prognosis
• do not exist in isolation from each otherResource use is determined by
the extent of co-morbidity, not
by the presence or absence of
particular diagnoses.
Management focused primarily on diseases
does not make sense for primary care.
The benefits of primary care (person-focused,
comprehensive, and coordinated) are greatest
for people with high morbidity burdens.
This is at least part of the reason why disease
management has not proven useful in
improving health. Even the chronic care model
will not be useful unless it is carried out in the
context of good primary care.
Primary care performance measurement using
disease-oriented guidelines will
• create inappropriate incentives in caring for
people with multiple conditions
• create incentives based on flawed evidence
(inadequate outcomes; unrepresentative
populations)
• create perverse incentives based on easily
measured rather than important
characteristics
• create incentives for avoiding the care of
disadvantaged populations
