Drug shortages cause hospitals to use older types of medicines

Hospitals across the country are running out of key drugs used in surgeries and to treat some diseases, including cancer, causing doctors to turn to older treatments.

In some cases, hospitals are paying higher prices to get their patients necessary care because wholesalers are hoarding needed medicines.

Part of the shortage is being caused by manufacturing issues and quality-control problems at a number of companies that include Lake Forest, Ill.-based Hospira Inc., one of the primary makers of generic injectable prescription medicines, as they respond to the federal government’s crackdown on drug safety. The quality issues can range from finding toxins and “particulate matter” in medicines to workers inaccurately filling out the required paperwork to verify that the drugs, as well as the devices used to intravenously deliver the products to patients, are safe and effective.

Even after a company restarts production of a drug, it takes time for a plant to catch up to the back orders. And injectable drugs in particular, unlike pills and tablets, tend to require long lead times to produce.

“These are the worst shortages I have ever seen,” said Thomas Wheeler, a hospital pharmacist for three decades and director of pharmacy for Advocate Illinois Masonic Medical Center in Chicago. “The most troubling aspect is that it is critical drugs for which there are limited alternatives. Many are involved in cancer care and surgery.”

About 150 drugs are in short supply — triple the number from just five years ago — according to the American Society of Health-System Pharmacists, a trade group that works with hospital pharmacists on ways to deal with the shortage. About 60 of those are considered by federal health officials “medically necessary,” and they include prescription medicines used to treat or prevent a serious disease or medical condition.

Drugmakers say they are obliging tougher safety rules put in place by the Food and Drug Administration, which has intensified scrutiny to avoid allowing unsafe medicines on the market. The FDA came under fire for its role in monitoring the blockbuster pain pill Vioxx, which was pulled off the market in 2004 by its manufacturer, Merck & Co., after the drug was linked to heart attacks and strokes.

The drug shortage is being exacerbated by consolidation in the pharmaceutical industry, which leaves fewer companies making drugs. For example, Teva Pharmaceuticals makes generic forms of certain cancer medications. So when quality issues temporarily closed its plant in Irvine in April, medical professionals were faced with limited supplies of an array of cancer drugs.

In addition, some drug companies have exited the business of making older, generic injectable drugs, which typically aren’t as profitable as newer brand-name medicines. That puts additional production pressure on the remaining makers of these generic treatments.

Take propofol, a popular anesthetic for surgeries and other medical procedures. Teva decided to exit the propofol business last year after a quality issue with the drug in 2009. In a statement, the company said it believed its “existing, approved technology is not suitable to ensure that we can consistently produce the product to Teva’s high quality standard.”

Teva’s decision came around the time another propofol maker, Hospira, had to stop shipping the drug because of quality issues in its production process. Last summer, the FDA allowed Hospira to begin production again. But the company said its new manufacturing process needed a certain amount of time to ramp up production and fill back orders.

The drug shortages have gained the attention of members of Congress. This month, Sens. Amy Klobuchar (D-Minn.) and Bob Casey (D-Pa.) introduced legislation that would require drugmakers to give the FDA an early notification “when a factor arises that may result in a shortage,” according to a joint statement.

Hospitals are finding ways to deal with the lack of availability.

At Provena Health, which has six facilities in Illinois, products in short supply have had to be moved “from one hospital to another,” spokeswoman Lisa Lagger said.

Other hospitals are dealing with the supply problem by turning to older medicines. Although these drugs can be just as effective, the lack of familiarity among medical professionals can lead to improperly calculated dosages.

About 35% of the healthcare professionals responding to a survey on drug shortages said they “experienced an error that could have led to patient harm during the past year,” according to an Institute for Safe Medication Practices study released in September.

There were more than 1,000 “errors and adverse patient outcomes” reported by those surveyed. Those errors and adverse outcomes were tied to more than 50 drugs on the shortage list that became abruptly unavailable, the institute said at the time the study was released.

Some hospitals are escalating the training of doctors, nurses and others who administer these older drugs, which can require larger dosages or have different side effects than newer treatments.

If Illinois Masonic’s intensive care unit can no longer get propofol, critical care pharmacist Aaron Hoffman said, patients will have to be given benzodiazepines or fentanyl, a shorter-acting narcotic.

For most patients, this would “not be a huge issue,” he said. But in the case of patients with severe liver failure, there could be toxicity concerns with the older drugs.

Some medical facilities have turned to secondary suppliers when their primary source for drugs has run out of needed medicines. And that has caused hospitals to pay double or more for certain drugs because they are working with a supplier that normally doesn’t sell them large volumes of a product.

The drug industry believes the issue will resolve itself relatively soon, and companies say the government’s tougher rules should make consumers and medical professionals feel more confident about their products.

Teva said its Irvine facility would begin producing cancer medications, including many in short supply, next month.

And Hospira has ratcheted up spending on its manufacturing facilities and quality systems. The company hopes to be caught up with production by the second quarter.

On a conference call with analysts and investors this month, Hospira Chief Executive Christopher Begley said the company’s efforts to meet the FDA’s “higher benchmark” would help the company long term.

“We see light at the end of the tunnel,” Begley said.
