It notes that patient boarding for over 6 hours is correlated with increased mortality and longer hospital stays. It also reports that over 20 million unnecessary patient days and over $100 billion per year are lost due to operational inefficiencies while 39% of hospital beds remain unoccupied. The document advocates for better operational efficiencies and patient flow to help address these issues.
