LINCOLNSHIRE, Ill., June 6, 2013 /PRNewswire/ -- To mitigate rising health care costs, an increasing number of companies are considering adopting strategies that will improve the way they pay for health care services in the future, according to new survey data by Aon Hewitt, the global talent, retirement and health solutions business of Aon plc (NYSE: AON). (Logo: http://photos.prnewswire.com/prnh/20100719/AQ37264LOGO) According to Aon Hewitt's survey of nearly 800 large and mid-size U.S. employers covering more than 7 million employees, 53 percent said that moving toward provider payment models that promote cost effective, high quality health care results will be a part of their future health care strategy, and one in five identified it as one of their three highest priorities. "As health care costs continue to rise, a growing number of employers want to ensure that the health care services they are paying for are actually leading to improved patient outcomes," said Jim Winkler, chief innovation officer for Health at Aon Hewitt. "Just as employers are being more requiring of their employees to take control of their health, employers are seeking to hold providers more accountable. They are beginning to work directly with health plans to embrace more aggressive techniques to reduce unnecessary expenses and create more efficiency in the way they purchase health care." According to Aon Hewitt's survey, the ever-shifting health care landscape has created a broad array of tactics that employers are considering: Increasing Focus on Pay for Performance Models Thirty-one percent of employers said they decrease or increase health care vendor compensation based on specific performance targets, and another 44 percent are considering doing so in the next three-to-five years. Additionally, while just 14 percent of employers currently use integrated delivery models, including patient-centered medical homes, to improve primary care effectiveness, another 61 percent plan to do so in the next few years.
