Dataset: Medicare Health Outcomes Survey (HOS)

Basic Information
Dataset full name: Medicare Health Outcomes Survey
Dataset acronym HOS
Summary The Medicare HOS is a longitudinal survey of a nationally-representative sample of the beneficiaries enrolled under the Medicare Advantage plan or Medicare managed care (HMO) plan. The survey selects a random national sample of beneficiaries from each participating Medicare Advantage Organization (MAO) who are surveyed in the spring. The same cohort is re-surveyed after two years. The main objective of the HOS is to collect information on beneficiaries related to physical health and mental health in order to track and improve the quality of Medicare Advantage program. A modified version of the Medicare Health Outcomes Survey-Modified (HOS-M) is administered to vulnerable Medicare beneficiaries with the greatest risk of poor health outcomes. The main goal of the HOS-M is to assess the frailty of the population in these health plans in order to adjust reimbursement rates for this population. These beneficiaries are enrolled in the Program of All-Inclusive Care for the Elderly (PACE).

Strengths and limitations
Strengths Longitudinal design allow researchers to determine trajectories of physical and mental health status. Dataset employs a combination strategy of data collection (administrative and survey). Adequate and appropriate data documentation available.
Limitations Data collection is limited to only those individuals enrolled under Medicare advantage plan (HMO plan) thus excluding all enrollees on Medicare fee-for-service plan.
