Hospital executives have expressed frustration when essential drugs like heart medicines have become scarce, or when prices have skyrocketed. Now, some of the country's largest hospital systems are taking an aggressive step to combat the problem: They plan to go into the drug business themselves, in a move that appears to be the first on this scale. This is a shot across the bow of the bad guys," said Dr. Marc Harrison, the chief executive of Intermountain Healthcare, the ... hospital group that is spearheading the effort. Several major hospital systems, including ... the nation's largest nonprofit hospital group, plan to form a new nonprofit company, that will provide a number of generic drugs to the hospitals. The Department of Veterans Affairs is also expressing interest in participating. The idea is to directly challenge the host of industry players who have capitalized on certain markets, buying up monopolies of old, off-patent drugs and then sharply raising prices, stoking public outrage and prompting a series of Congressional hearings and federal investigations. The most notorious example is of Martin Shkreli, the former hedge fund manager who raised the price of a decades-old drug, Daraprim, to $750 a tablet in 2015, from $13.50. Hospitals have also struggled to deal with shortages of hundreds of vital drugs over the past decade, ranging from injectable morphine to sodium bicarbonate (the medical form of baking soda), shortfalls that are exacerbated when only one or two manufacturers make the product.
