Type
not stated
Format
Tabular survey microdata (respondent-level weighted panel with year, segment, plan type, switch outcome, NPS, channel-preference and benefit-usage fields) plus long-form qualitative responses; delivered today as PDF reports and an interactive county-level tool
Volume
est. thousands of respondent-level records per year and plausibly 20,000-40,000+ respondents cumulatively across the multi-instrument annual cadence (a 3,100+ sample on the flagship study alone, with several additional instruments per year), each carrying dozens of measures, plus county-level disruption data covering the national MA/PDP universe
Users
No registered-user product — respondent panel is the asset: 3,100+ Medicare eligibles on the 2025 flagship wave plus separate ANOC Pulse, Onboarding, AEP Gut Check and OEP instruments each year; client base is subscribing payers/vendor accounts
History
12 years
Update frequency
not stated
Growth
Active — published the 2025 Medicare Member Experience Study on 10/31/2025 and a 2026 study already exists as a live product page; the disruption tool is described as updated even where CMS crosswalk files were unavailable, indicating continuous fieldwork
Launched
~2012-2015 (organization record established ~2015 in Minneapolis with 21 staff; the firm's study series and client-services structure indicate it was operating commercially at that point, and its MA analysis references the multi-year term-member history since the inception of the Medicare Advantage program)
