Background: Continuity
Continuity of care with a provider a key component of primary care
Little is known about importance of continuity for patients with type 2 diabetes
Self-care activities: diet, exercise, glucose monitoring, are fundamental in the management of DM.
Background: Stages of Change
People move through “Stages of Change” for self-care behaviors:
Precontemplation
Contemplation
Preparation
Action
Maintenance
Little is known about Stage of Change for self-care activities for diabetes
Stage of Change Question
Do you always follow your diabetic diet in the way that you were instructed?
No, and I do not intend to
in the next 6 months [Precontemplation]
No, but I plan to
in the next 6 months [Contemplation]
No, but I plan to
in the next month [Preparation]
Yes, I have been
but for less than 6 month [Action]
Yes, I have been
for more than 6 months [Maintenance]
Research Questions:
Is Continuity of care associated with glucose control?
Is Continuity of care associated with Stage of Change for diabetes self-care behaviors?
If so, is the relationship between Continuity and glucose mediated by Stage of Change?
Hypothetical Model
Methods
Patient surveys:
20 per physician
Continuity: physician visits last 12 months
Stage of Change: 5-item questionnaire
Diabetes control: glycosylated hemoglobin [hgb a1C]
Chart data:
last 2 blood pressure measurements
Office Procedure
20 Consecutive patients with type 2 DM
Nurse records most recent hgb a1C and last 2 BP readings
Patient completes survey, returns it to office staff.
Surveys mailed to TAFP R-Net Coordinator (Anna Jenkins)
Results
9 practices, 118 surveys,
hgb a1c recorded: n=97
56.1% female
mean age: 55.4 (std. dev’n: 12.7)
race/ethnic background:
Hispanic 50%
Non-Hispanic, White 37.2%
African American 11.5%
Descriptives
Education: 76.6% finished high school
Income:
< $10,000: 25.9%
> $30,000: 31.5%
How long a patient of this:
Doctor: 4.9 years
Practice: 6.1 years
Same doctor now as 12 months ago?
77.7% Yes
Stages of Change
Glucose Control
Continuity
Usual Provider Continuity [UPC] =
visits to PCP/total visits in last 12 mos
Mean 0.72 (std dev’n: 0.25)
Question #1
Is Continuity of care associated with glucose control?
No: Continuity & hgb a1C
(Pearson r = -.032, p = .81)
Question #2:
Is Stage of Change associated with glucose control?
Yes: hgbA1C & Stage of Change
Question #3
Is Continuity of care associated with Stage of Change?
Sometimes: Continuity Score and Stages of Change
How are Continuity and Glucose Related?
Conclusions
Continuity of care was not associated with glucose control in this study
Patients with higher levels of continuity are significantly more likely to be in maintenance stage for exercise
Patients in maintenance stage of change for diet and SMBG have significantly better glucose control

TAFP R-Net
10. Nobody, except our patients (and us) knows what FP’s do.
9. Sometimes, even our patients don’t know
8. Often, even we don’t know
7. Managed Care loves us, but for the wrong reasons
6. It’s hard to improve practice without understanding it

5. Because it’s fun!
4. We need to know how to take care of the “problems that most of the people have most of the time.”
3. Practice should be based on science.
2. Family Practice is the hardest science of them all.
1. Knowledge is power.
