When the manager of singer Gurrumul looked at Royal Darwin Hospital's clinical notes on the acclaimed indigenous artist his reaction was: "They've just put him in a corner to die."
Mr Grose has accused the hospital of either being incompetent or racially profiling Gurrumul and failing to operate on him when he was admitted on Easter weekend for internal bleeding related to his liver and kidney problems, leaving him for eight hours without surgery after he vomited blood.
The hospital says there was no delay and that Gurrumul was treated appropriately.
ARIA-award-winning Gurrumul was Northern Territory Australian of the Year and is one of the country's most famous Aboriginal musicians.
Mr Grose says the hospital assumed Gurrumul's health problems were caused by alcohol abuse, as opposed to the hepatitis B he contracted as a child.

The racial profiling allegations were "completely ridiculous", said hospital spokesman Professor Dinesh Arya.
"It is nonsensical to even consider that very hard-working health professionals would consider racially profiling anyone or making clinical decisions not based on clinical need," he told reporters.
"Yes, we do prioritise, but prioritisation occurs on the basis of clinical need, and occurs on the basis of urgency."
He denied Mr Grose's allegations that Gurrumul's clinical notes referred to him being a drinker.
"No, not at all," he said.
"There is no one who comes to our service who gets either labelled or documented as a drinker, that's completely inappropriate."
Mr Grose maintains that the clinical notes contain references to alcohol.
"It clearly says to me that he is Aboriginal, as a result of heavy drinking his conditions has developed. He's unlikely to survive, therefore not sure really if any action is needed, that's the message essentially in his notes," he said.
He said both he and Gurrumul's specialist had sighted the notes.
"I was shocked, I looked at someone and said, 'they've just put him in the corner to die'."
Professor Arya said he personally visited Gurrumul on Tuesday, which Mr Grose also refutes, saying Gurrumul had no memory of seeing anyone, and nor did the ward staff.
"I need the hospital to admit now that there's a problem in the system," Mr Grose said.
"We don't know what happened but whatever it was, it wasn't right. The decisions made weren't right."
The hospital is undertaking an internal review to determine whether Gurrumul received appropriate care and what improvements if any can be made.
Gurrumul will undergo day surgery on Thursday, and is in good spirits, Mr Grose said.
