Employers face an average increase of 10.6 percent in health care costs in the next 12 months, according to a survey by Aon Consulting of more than 70 leading health care insurers, representing more than 100 million insured individuals. The survey projects that health care costs will increase by 10.6 percent for HMOs, 10.5 percent for POS plans, 10.7 percent for PPOs and 10.5 percent for CDH plans. These represent the lowest trend rate increases since the study began in 2001 and are slightly lower than one year ago, when HMO cost increases were 10.9 percent, 10.8 percent for POS plans, 11.2 percent for PPOs and 10.7 percent for CDH plans. Aon notes that while the medical trend rate is still more than twice the consumer price index, the continuing slow down in health care cost rate increases is encouraging. It attributes the decrease in the medical trend rate to more employers and employees taking advantage of wellness, health promotion and consumer driven programs.
