Design and feasibility of a national Medicaid Access Survey with state-specific estimates

Abstract

This article presents the results of a study to design and assess the feasibility of conducting a national Medicaid Access Survey to generate timely, state-specific estimates of access to care for Medicaid enrollees. State-specific data on Medicaid access is especially relevant because state programs and environments vary considerably and are changing rapidly in ways that could influence access. We analyze (1) basic survey design parameters and instrument content, (2) alternative sampling approaches and their feasibility, (3) pilot test results, (4) the feasibility of using existing national surveys to generate comparison estimates for state-based surveys, and (5) estimates of the required sample size and costs for such a national Medicaid Access Survey. We conclude that a survey generating timely, state-specific estimates of Medicaid access is both feasible and affordable if attention is paid to key design challenges while keeping objectives and design simple.
