Hospitals fall short evaluating AI biases, study suggests
Hospitals are more likely to assess artificial intelligence and predictive models for accuracy than for potential biases, according to a study published Jan. 6 in Health Affairs. Researchers at the University of Minnesota School of Public Health analyzed data from 2,425 hospitals nationwide that participated in the 2023 American Hospital Association Annual Survey. Hospitals with higher operating margins, in-house model development capabilities or membership in a health system were more likely to evaluate models for bias.
The AARP Public Policy Institute published a report this month that concluded that prices for top Medicare Part D medications have almost doubled since being brought on the market. Leigh Purvis of the Public Policy Institute wrote that the growing drug prices are "challenging for Medicare Part D enrollees, who take an average of four or five prescription drugs every month and often face cost-sharing that is directly affected by drug price increases."
A new study shows that the risk of developing dementia at any time after age 55 among Americans is 42 percent, more than double the risk reported by older studies. That dementia risk translates into an estimated half-million cases this year, rising to a million new cases a year by 2060, according to the new work. Dementia involves progressive declines in memory, concentration, and judgment. The increasing number of cases is directly tied to the aging of the U.S. population.
More than 23 million people have selected coverage on the Affordable Care Act's exchange as part of open enrollment, according to data from the Centers for Medicare & Medicaid Services (CMS).

That means the number of people with marketplace coverage has grown by 11.6 million since the 2021 open enrollment period.
