Electronic Decision Support for Intervention in Poorly Controlled Type 2 Diabetes

1. Patients of selected St. Elizabeth Physicians Primary Care Physicians without a new
intervention related to the management of the patient's diabetes in the last 3 months
may be contacted via telephone by research staff.

2. During the telephone call, patients will be offered the opportunity to manage their
diabetic medication by following the PATH decision tool, explaining that PATH is a
computer program which finds a balance between low cost and high effectiveness. If
participation is elected, informed consent will be mailed with a follow up phone call
from staff, or an informed consent will be signed at their upcoming primary care office
visit. Some patients may be approached during their office visit, without a prior phone
call. Patients who do not have an eligible hemoglobin A1c on file, but are expecting to
have an eligible hemoglobin A1c value on an upcoming blood test may consent prior to the
blood test. If the hemoglobin A1c comes back >=7.0, the patient will continue following
protocol. If the hemoglobin A1c comes back <7.0, the patient will be categorized as a
screen failure, but will remain eligible for later enrollment. If the patient becomes
eligible and is later enrolled, the patient will be assigned a new study ID number.

i) If a patient elects not to participate, the reason for not participating may be
recorded in the screening log. As part of the standard of care, patients not selecting
the study will be offered an appointment outside the study to address their poorly
controlled diabetes.

ii) If a patient elects to participate and a hemoglobin A1c has not been drawn in the last 3
months, one will be ordered through their insurance as part of the standard of care, to be
used as the baseline hemoglobin A1c for Path calculations.

3. Patients who agree to participate maybe contacted by telephone by a licensed provider (MD
or ARNP) who will enter non identifiable data from the patient's chart into the PATH decision
support software. Information will be gathered from the Epic EHR and the questionnaire found
on Article #2. This questionnaire may be completed by the patient, or by staff during patient
interview. Some patients may complete this process during their scheduled office visit.

i) Study specific items will be recorded as illustrated in Article #4 ii) Time spent
populating the data will be recorded, as part of the secondary analysis.

4. Patient and provider will discuss options on the telephone or during the office visit, and
will further customize regimen selections while discussing risks and benefits. Once a regimen
is selected, the score and content of the regimen will be recorded by the provider.

i) Regimen selected will be classified by "partial recommendation, full recommendation,
alternate recommendation, or "no action" in relation to the options presented by the PATH
program. --> final score of the course of action will be calculated and recorded.

i. Definitions:

1. Full recommendation: the regimen selected is the exact regimen shown in PATH, with no
additions or deletions.

2. Subset recommendation: the regimen selected is a subset of a regimen shown in PATH
(i.e., with one or more deletions), with no additions.

1. Example: PATH recommends the regimen (A, B, C, D)

2. Valid subset regimens would include (A, B, C), (B, C, D), (A, B), and (A), among
others.

3. Superset recommendation: the regimen selected contains all of the elements of one
regiment recommended by PATH, plus at least one other therapy.

1. Example: PATH recommends the regimen (A, B, C)

2. A valid superset recommendation would be (A, B, C, Exercise).

4. Alternate recommendation: Any other combination of additions and deletions from a PATH
recommended regimen.

5. No action: No regimen was selected.

5. Manufacturer Discount coupons will be offered and mailed if applicable as part of the
normal procedures of the primary care office.

i) Mailed coupons will be documented in the participant's study chart.

6. If Path is completed over the phone, the patient will be offered immediate "in person"
follow up (traditional visit) to review the changes. As this is appropriate to the treatment
of diabetes, traditional CPT billing will be used and the in-person visit will be billed to
insurance as part of standard of care.

i) Patient's choice to participate in a traditional office visit will be recorded in the
participant's study chart.

7. Follow up visit or phone call will be scheduled at 3 months (+/- 30 days) with repeat
hemoglobin A1c, following the standard of care for the treatment of diabetes. The 3 months
(+/- 30 days) follow up window will be calculated from the date patients are informed of
their new medication regimen. During this visit, diabetes evaluation will follow the standard
of care including adherence, efficacy, and adverse events. Adverse events will be categorized
through the "drug intolerance" and "comorbidities" section of the PATH software. See Article
#6 i) Type of follow up will be recorded ("phone follow up, live follow up, no follow up").
Reason for no follow up will also be documented.
