Declarations
:
: The Institutional Review Board (IRB) at the University of Nevada Las Vegas (UNLV) found the current study to be exempt with negligible risks to subjects. It was practically not feasible to receive patient consent from a deidentified large secondary dataset. The federal government intentionally made it impossible to link any hospital discharge in NIS with the state the patient resides in to protect the patient’s privacy and confidentiality. The patient consent process was a part of the UNLV IRB review and the IRB approved this study (IRB no. 1098939–3). All methods were carried out in accordance with Helsinki declaration.
