Medication Mistakes And Pharmacy Errors Continue To Be A Large Problem

Prescription Drugs Wrongly Prescribed Or Improperly Dispensed Are Preventable Adverse Events Which Need To Be Reduced In Number -- And This Can Be Done

(Posted by Tom Lamb at DrugInjuryWatch.com)

In a February 14, 2008 article, "1 in 10 patients gets drug error", Boston Globe reporter Patricia Wen presented some disturbing data from a study which examined adverse events involving prescription errors that occurred in six undisclosed Massachusetts community hospitals:

One in every 10 patients admitted to six Massachusetts community hospitals suffered serious and avoidable medication mistakes, according to a report being released today by two nonprofit groups that are urging all hospitals in the state to install a computerized prescription ordering system.

The report is the first large-scale study of preventable prescription errors in community hospitals, and its author, Dr. David Bates of Brigham and Women's Hospital in Boston, said he was surprised that these mistakes were so frequent in these community hospitals....

The researchers reviewed a total of 4,200 randomly selected patient medical charts at the six community hospitals, covering stays from January 2005 to August 2006. An average of 10.4 percent of patients suffered a preventable "adverse drug event" - defined as a case in which the patient was given a drug even though the medical records noted that the medication could trigger a drug allergy or that the dose given would exacerbate a medical condition. Medication errors were counted only when patients suffered serious reactions, including going into shock or suffering kidney failure. In nearly every instance, the patients remained in the hospital longer to recover from the mistake. Nobody died from any of the mistakes, researchers said.

This February 14 article in the Globe goes on to describe how the computerized prescription ordering system mentioned above works, as well as what types of results its use can produce:

[T]e computerized physician order entry system, which requires doctors to type into a central database every medical order, including prescriptions, diagnostic tests, and blood work. The doctors' orders are matched against the patient's medical history, triggering red flags to prevent problems related to drug allergies, overdoses, and dangerous interactions with other drugs.

Bates said that after this system was put in place at Brigham and Women's Hospital in 1995, preventable medication errors declined by 55 percent over the next two years....

Ms. Wen includes in her article various discussions about how medical insurers, government officials, and healthcare providers, all, would benefit from the computerized system being used at more hospitals in Massachusetts and across the nation.

Turning to another aspect of medication errors, on February 12, 2008 the Indianapolis Star published a lengthy USA Today article, "Too many prescriptions, too few pharmacies", which reported the results of an investigation that USA Today conducted:

The investigation reviewed policies and alleged errors at rivals Walgreens and CVS, the nation's two largest drugstore chains, which fill nearly one-third of all retail prescriptions nationwide. It included a review of scores of lawsuits, as well as pharmacy board disciplinary actions in 10 states and interviews with pharmacists, drug-error victims, their families and attorneys. Some common factors emerged:

• Too many prescriptions, too few pharmacists....
• An emphasis on speed....
• A reliance on technicians....
• Pharmacist incentive awards....
• Counseling gaps....

We learned from this February 2008 USA Today article about prescriptions being improperly filled by pharmacists that, remarkably, the North Carolina Board of Pharmacy is the only state board that requires all major drug errors to be reported to the agency.

The online version of this USA Today article has an interactive graphic component, "How prescriptions are filled and where errors can occur", which gives one a better idea about what goes on behind the counter at your typical chain-store pharmacy.

For anyone interested in the causes and effects of medication errors, both of these February 2008 news reports are well worth your time.
