Minimal Data Set

NAQC published the original Minimal Data Set (MDS) in mid-2005 and all quitlines in the U.S. and Canada had adopted it by early 2006. The MDS includes required and optional questions that are asked of callers at intake and seven-month follow-up. The standardized MDS questions create data that is useful for delivery of cessation services, surveillance of quitline callers and evaluation of quitlines. 

A major strength of the MDS is its ability to evolve over time to reflect new topics and issues of importance to both the quitline and research communities.

Announcement of MDS Updates – October 2019

In response to member feedback and concern about the increasing length of time for intake, NAQC initiated a review of MDS intake and follow-up questionnaires. The review was conducted from October 2016 to October 2019, and included a robust process of gathering feedback from members, convening a workgroup, gathering current intake and follow-up questionnaires used by quitlines, and consultation with subject matter experts.

Below are key documents presenting the information on changes to the MDS. If you need assistance or have questions about the MDS please contact
