How is a home health aide different from a personal care aide or a private sitter?
The difference is training, oversight, and scope. A certified home health aide has completed a state-approved training program and met New York State Department of Health requirements. A personal care aide typically has less training, and a private sitter hired informally usually has none of the structure, no agency, no supervision, no backup.
When you hire privately, your family also takes on employer liability and scheduling risk. With an agency aide, there's insurance, RN supervision, documented care, and a replacement when your regular aide is sick. The certificate is the start of the difference, not the end of it.
