The short answer is yes, hospice is available in home in Ohio.
Hospice eligibility requires a terminal diagnosis with a life expectancy that is less than 6 months if the disease process runs it's expected course. There are also more defined eligibility criteria for certain diagnosis. This is Medicare/ Medicaid guidelines which are the "gold standard" for hospice eligibility. Most types of insurance go by this, but a few private insurances have additional stipulations. Eligibility is assessed on an ongoing basis and more formally at the end of each certification period. After 2 - 90 day certification periods, additional 60 day certification periods available. Patient's can continue hospice as long as they continue to meet the criteria (which also typically evaluates progression of the disease process/ decline).
Medicare/ Medicaid also outlines the levels of care and basic services a hospice is required to provide within the US so I'm guessing this is standard no matter what state a person is in. Routine hospice care is provided at a patient's place of residence (private residence, group home, SNF, ALF etc).
Hospice facilities are typically only for individuals who have symptom management needs that cannot be managed in any other setting (pain, dyspnea, seizures, anxiety, very complex/ complicated wound care etc). This is referred to as General Inpatient Level of Care and is intended to be short term in most cases; just until symptoms are managed and plan is place for continued management after transfer to another location (returning to routine level of care). Hospice facilities are sometimes also used for the respite benefit; which is up to a 5 night stay to allow for a caregiver to get rest/ relief from caregiving.
A good starting place would be for your friend to either ask their medical provider if they are appropriate for hospice care or contact a hospice provider in the area in which they live.
