McKernan, S.C.; Pooley, M.; Ingleshwar, A.; Momany, E.T.; Damiano, P.C.


This report is one of a series that evaluates the Dental Wellness Plan (DWP) provider network adequacy; previous reports examined network adequacy at baseline1 and at the end of the rst program year2. This current report describes the dentist network during the second year of the DWP, May 2015 through April 26. We also make comparisons with Year 1 (May 2014 – April 2015) to describe changes over time, where appropriate.

The two main types of outcomes considered in this evaluation include dentist supply measures (e.g., dentist ratios) and distance measures (e.g., distance to the nearest dentist). Comparisons are made between DWP members, members of the traditional Medicaid State Plan (MSP), and Delta Dental of Iowa (DDIA) commercial bene ciaries.
