Role of PCPs in diagnosing dementia in traditional Medicare and Medicare Advantage.

ABSTRACT:

Introduction

This paper quantifies how incident dementia diagnosis rates vary for similar beneficiaries in traditional Medicare (TM) and Medicare Advantage (MA) seen by the same primary care provider (PCP).

Methods

This cohort analysis used 2016 to 2018 data for Medicare beneficiaries. Using a propensity score-matched sample of beneficiaries with similar likelihood of MA enrollment, we estimated linear probability models with PCP fixed effects of incident dementia diagnosis in 2017 for beneficiaries in MA relative to beneficiaries in TM.

Results

Among a matched sample of 15,410,030 beneficiaries, accounting for both provider and patient characteristics, the incident dementia diagnosis rate was 0.11 percentage points lower for MA beneficiaries compared to TM beneficiar
