This study's aim was to examine the impact of pandemic emergency Home- and Community-Based Services (HCBS) payments on the continuity and security of people with intellectual and developmental disabilities (IDD). Using a multilevel logistic regression, we analyzed secondary Personal Outcome Measures interviews from 738 people with IDD (March 2020 through April 2022), and state pandemic emergency HCBS payment data from 16 states. The odds of people with IDD experiencing continuity and security during the pandemic increased by 3% for every 1% states increased their payment rates, and by 398% when states offered retainer payments. Increased reimbursement rates and retainer payments can help providers maintain operations and promote the continuity and security of people with IDD.
