The OHS report was designed for a specific managed care plan in Florida called Oral Health Services (OHS). once it's exports it's then uploaded to their service and is used in some capacity. Though we do not have anything on what it is exactly used for by that group.
This report is rarely asked about so we don't really have any documentation for what data is in it.
From what i can tell from running it on my data it shows Columns (in .csv format) for
SSN | Home phone | another unknown origin number | Last name | First name | another unknown origin number
I'm attaching the PDF that we have on file for it though if you'd like to take a look at it.
