How long after a complaint is filed before the DOH starts an investigation of an ltc center? My company recently got told the DOH is doing an investigation of my facility due to a complaint, I have no idea with regards to what though. No recent complaints or incidents in the last couple months. I haven't even had an incident report filed in 60 days, it was a nice summer for us. I can't imagine what they are coming to investigate. In the past the DOH call within a week of an incident and asks for charts and report copies I'm a little confused what the complaint was all about. Could someone have filed a report months ago and the DOH is just getting around to the investigation. And why are they not asking for a specific chart?
