The National Diabetes Prevention Program Diabetes Prevention Recognition Program,
Understanding and Managing Sequences. Presentation Objectives.
The objective of this presentation is to provide CDC-recognized organizations with a detailed
explanation of how participants are evaluated according to when they start the National DPP
lifestyle change program. We will define and explain the concept of the sequence. It is
important that organizations fully understand sequences to understand the evaluations that
will be performed and reflected on the evaluation reports they will receive
once data have been submitted. Having full understanding of how sequences impact evaluations
and outcomes will allow you to understand the reports you receive.
Data Submission Timeline. Once your organization has been fully approved, CDC will send you a data submission timeline
specific to your organization. There are two dates that are important to your organization.
The first is your approval date. The approval date
is the date that your application was approved and the date that you can start holding classes.
Your effective date is the first day of the month following the approval date.
The month of your effective date will set your data submission timeline. Each organization will
submit data every 6 months, starting from the effective date. Defining a Sequence part one.
The periods between data submissions are referred to as sequences. The one exception to this is the
period between the approval and effective dates. This period is called Sequence 0. No
data submission is made at the start of Sequence 1, which is the month of the effective date.
Defining A Sequence part two.
Sequences are used to determine when a participant cohort will be evaluated.
All cohorts that start within the same sequence will be evaluated together.
This could be a single cohort, or it could be multiple cohorts.
Cohorts and the participants in those cohorts will never change sequences.
Sequence assignment has nothing to do with a participant’s progress through the program.
To effectively track your organization’s progress toward advancing in recognition, you should
carefully track the progress of each cohort to determine who will be eligible for evaluation.
Evaluation Process - Cohort Timeline for Participant Evaluation. This timeline is an
example of who will be evaluated at the time the organization makes its required data submission.
Evaluations are performed on participants enrolled in cohorts where the cohort’s first
session date is at least one year but not more than 18 months before the submission due date.
We do not evaluate anyone who has already been evaluated.
If you look at the 12-month point on the submission timeline, the point where the Sequence
2 submission is made, you see that this is the first possibility for an evaluation.
This will only be possible if at least one cohort held its first session
after your approval date but before your effective date: Sequence 0. It is denoted here
by the red “Sequence 0”. We will talk in more detail about Sequence 0 in a moment.
Continuing with this example, you can see that at the 18 month/Sequence 3 submission point in your
timeline, we will evaluate participants who begin the program in Sequence 1.
At the 24-month/Sequence 4 submission point in your timeline, we will evaluate participants
who began the program in Sequence 2. This process continues every 6 months.
Sequence Zero Evaluations. Let’s go over the Sequence 0 evaluation in more detail.
As previously stated, Sequence 0 is the period between an organization’s approval and effective
date. We will only perform an evaluation at the 12-month point in the timeline if it benefits
the organization. That is, if there are at least 5 completers associated with this sequence. If the
organization has less than 5 completers associated with Sequence 0, then these participants will be
added to the Sequence 1 participants who will be evaluated at the 18-month/Sequence 3 point in
the timeline. A completer is a participant who attended at least 8 sessions in the first six
months and whose time from first session attended to last session attended was at least 9 months.
Sequence Impact on Participants. Organizations are not required to have evaluations every 6 months;
however, they are still expected to submit data every 6 months.
We understand that not all organizations are able to start new cohorts more than once a year.
This point emphasizes the importance of tracking cohorts start dates. It also enables you to
understand the progress and evaluation reports you will receive. This concludes this presentation.
Thank you for participating in the Diabetes Prevention Recognition Program.
