Basic Information
Dataset Full Name National Nursing Home Survey
Dataset Acronym NNHS
Summary The NNHS is a nationwide sample survey of nursing homes, staff, and residents. It collects data at the provider and resident level. The provider-level characteristics include the number of beds, ownership status, certification status, and provision of services and program to residents. The resident-level characteristics contain demographic characteristics of residents, health-related factors, services received, and source of payment used by residents. The survey uses Computer-Assisted Personal Interviews (CAPI) for data collection from nursing home administrators, staff, and residents.
