The Medicare Current Beneficiary Survey (MCBS) is a longitudinal survey of a nationally representative sample of the
Medicare population sponsored by the Centers for Medicare & Medicaid Services (CMS) and administered by NORC at the
University of Chicago. The MCBS has been at the forefront of COVID-19 vaccine data collection, closing important policy gaps
by providing more timely data than administrative sources. Notably, MCBS vaccination data can be supplemented by other
MCBS data on key factors like socio-demographics and chronic conditions. The MCBS began collecting COVID-19 vaccination
data in early 2021 after the first vaccine received emergency use authorization. In response to rapidly changing vaccine
availability and booster guidance, MCBS COVID-19 data collection was redesigned in Winter 2022 to add flexibility around
policy changes and improve data quality using a vaccine roster. For each dose, the roster collects the date, manufacturer,
and location received, enabling policymakers to answer questions about vaccination progress for sub-groups. We discuss key
considerations in the design and implementation and preliminary findings from the field and data review.

Many federal surveys use proxy respondents ('proxies') when sampled individuals are unable to participate on their own. This
may increase coverage and flexibility, but also could introduce operational challenges. The Medicare Current Beneficiary
Survey (MCBS), a nationally representative, longitudinal survey of the Medicare population, is conducted by the Centers for
Medicare & Medicaid Services (CMS) through a contract with NORC at the University of Chicago. For beneficiaries living in
the community, the interview is typically conducted with beneficiaries directly, but proxies are often needed for beneficiaries
with physical or mental disabilities or who are deceased. When the MCBS transitioned from in-person to phone interviewing
due to the Covid-19 pandemic, it seemed plausible that the mode change would affect when proxies were needed. This study
investigates changes in the overall proportion of interviews conducted with proxies, characteristics associated with proxy
interviews, and differences in data collection effort between beneficiary and proxy interviews in rounds of data collection
completed before and after the mode transition.

Home health care for Medicare beneficiaries is of growing interest to Medicare policy. According to the U.S. Department of
Health and Human Services (2016), Medicare paid $18.1 billion for home health care for beneficiaries with postacute or longterm skilled care needs. The Medicare Current Beneficiary Survey (MCBS), a nationally representative survey of the Medicare
population conducted by the Centers for Medicare & Medicaid Services (CMS) and administered by NORC at the University of
Chicago, is well-positioned to collect robust home health data. CMS and NORC redesigned the MCBS Home Health
Questionnaire (HHQ) to provide accurate home health data, informed by health care research, policy, and the ability to link
survey data to administrative claims. This presentation discusses how home health differs from other care, why the MCBS is
positioned to collect these data, evaluating the existing vs. preferred data collection design, and key features of new HHQ.
The redesigned HHQ collects data in a way that closely aligns with home health delivery, making it possible for MCBS data to
better support analyses on impact of payment and delivery system reforms and home health care use.
The Impact Of Single- And Mixed-Mode Designs On Establishment Survey Participation, Nonresponse Bias, And Costs

The IAB Job Vacancy Survey (IAB-JVS) is a voluntary nationally-representative establishment survey that quantifies the size
and structure of job vacancies in Germany. Since 2011, it has been carried out using a concurrent mixed-mode design, with
establishments receiving paper questionnaires and the option of online completion. However, this mode design is facing increasing costs and declining response rates. To counteract these trends, a more pronounced push-to-web strategy offers a
promising alternative. However, a change of survey mode might affect response rates bias, nonresponse bias and costs. To
test an implementation of an alternative mode design, a large-scale experiment comparing four self-administered mode
designs was conducted with 155,000 establishments in the 4th quarter of the 2020 IAB-JVS.
