Tarrant, also a Baltimore Democrat, said he hadn't heard concerns about such a registry being used to detect violations of federal law, but he said administrators' worries about oversight should not be a barrier to improvements in the system.
"If it improves health care, we all have to adjust to the growing pains," he said.
Rosenberg said he is aware that there are some concerns, including that the registry would be used to identify perceived violations of the Emergency Medical Treatment and Active Labor Act.
But he believes that the legislative process will provide opportunities for critics of the registry to voice their concerns, and said that provisions could be added to address those concerns.
"It just struck me that the bill is an opportunity to have a fuller discussion," Rosenberg said. "Just by getting the various parties to the witness table to testify on the bill ... would hopefully have a positive effect."
