The U.S. market for advanced patient monitoring systems has grown from $3.9 billion in 2007 to $8.9 billion in 2011 and is forecast to reach $20.9 billion by 2016, according to a study by Kalorama Information. Efforts to reduce costs in healthcare, avoid emergency room overcrowding, and prepare for a growing number of elderly patients in the years to come are a few of the drivers for the adoption of these systems. In Kalorama Information's recently published report, "Remote and Wireless Patient Monitoring Markets", researchers predict the U.S. healthcare system faces "a looming healthcare crisis of unseen proportions," and there will be fewer healthcare personnel and funds to address the industry's growing needs.
