Entered ER at 4:30pm with projectile vomiting and severe abdominal pain. Was evaluated by nurses and Dr rather quickly. Tests ordered. Treatment was excellent until shift change. Medication for vomiting wore off. Started calling for help at 11pm. No one came until after 3am. Had to unhook myself from IV, heart monitor, ect to use restroom. This was difficult as I was covered in bodily fluids. No beds available on the floor.
This occured due to understaffing not incompetence. The ER was very busy and not set up for long term care. Once on the floor treatment could not have been better. I did speak with a patient advocate prior to discharge concerning understaffing a critical area.
