Common Errors

Understanding the Prescription Drug’s Path through a Pharmacy can Reduce Error

December 28, 2009 | Lebowitz & Mzhen

In a recent study that our Maryland Pharmacy Error Attorneys have been following, USA Today investigated every step of a prescription’s path in a pharmacy—to uncover the potential for medication mistakes with each step of the filling process, that can lead to patient injury or wrongful death.

In the research, USA Today interviewed pharmacy experts and toured two pharmacies, a CVS and Walgreens, to study the six steps of the prescription filling process, and the potential errors that can happen along the way, as well as real cases that have caused actual injuries or death.

Step 1: Prescription received

When the customer drops off the prescription to the technician, or the doctor’s office calls in the prescription, errors can occur if a technician misunderstands a doctor’s handwriting, prescription codes and abbreviations or misunderstands the oral instructions over the phone. In one case, a doctor’s prescription for methadone read “sig 4 tablet BID for chronic pain,” which means “Please label (sig) this drug to say: take 4 tablets twice per day (BID) for chronic pain. The technician typed, “Take 4 tables by mouth as needed for chronic pain.” The patient allegedly died of an overdose of methadone.

Step 2: Prescription entry
A technician then scans the original prescription into the computer and manually enters the patient’s personal data, like name, address, date of birth and phone number, as well as drug information, strength, dosage instructions and quantity. If a technician incorrectly types the prescribed drug dosage, formulation or the patient’s medical condition, history or allergies into the computer, then serious errors can occur, including personal injury. Also if the wrong drug code is chosen in the computer system, it can be mistaken for a similarly named drug. In one instance, a pharmacy was asked to fill a prescription for compazine, an anti-nausea drug, (COM) and accidentally gave the patient a generic substitute for coumadin, a blood thinner (COU).

Pharmacy Mistake Leads to Wrongful Death—Rite Aid Faces Lawsuit

December 22, 2009 | Lebowitz & Mzhen

Our Maryland Pharmacy Error Injury Lawyers have been following the recent case filed last week on behalf of John Sheridan, a man who died after being prescribed the wrong dosage of a cancer medication.

According to the suit, Sheridan was prescribed Temodar, a powerful drug for brain tumors that was part of his treatment of cancer in September 2007. The prescription was allegedly written incorrectly, and Sheridan was wrongly prescribed 10 times the correct dosage—he reportedly took the medicine daily when it was only to be used every other week. Rite Aid Pharmacy allegedly dispensed the drug to Sheridan, without checking with Sheridan’s oncologist for a second opinion to clarify the prescription mistake.

The lawsuit accuses a Rite Aid pharmacy for contributing in the wrongful death of Sheridan, who reportedly had consumed toxic doses of the cancer medication. According to the Associated Press, the doctor who wrote the incorrect prescription has settled with Sheridan’s estate.

According to a 2006 report from the Institute of Medicine, at least 1.5 million Americans are injured by medication mistakes every year, and nearly 7,000 people die every year from medication errors annually.

QJM: How to Prevent Medication Errors and Injury with Balanced Prescribing

November 30, 2009 | Lebowitz & Mzhen

As Maryland Medication Mistake Attorneys we have recently read an article published in the QJM, the long-established leading general medical journal, on the topic of medication errors—giving an overview of what medication mistakes are, how they happen, and how to prevent them from happening in the future.

According to the article, published in August 2009, a medication error is a failure in the process of treatment that can lead to the harming or personal injury of a patient. Medication errors can often occur in:

• Prescribing faults: ineffective prescribing, irrational or inappropriate prescribing, under-prescribing and over-prescribing when deciding which treatment and dosage plan to take.

• Prescription writing: illegibility
• Formulation manufacturing: incorrect strength, misleading packaging
• Drug formulation dispensing: incorrect drug, formulation and label
• Administering the medicine: incorrect dosage, wrong directions for frequency, invalid duration of treatment
• Monitoring drug therapy treatment and drug treatment alteration when required

Medication errors can be classified, according to the article, by the use of psychological error classifications—knowledge-errors, rule-errors, action-errors, and memory-based errors. It is important to detect the medication mistakes, that can range from trivial to serious, and to create a working environment that is free of blame, and encourages the reporting of errors.

The article also recommends, “balanced prescribing” to avoid medication errors. In balanced prescribing, the mechanism of action of the drug should complement the pathophysiology of the disease—optimizing the balance of benefit to harm.

Alert for Public Safety—FDA Reports Medication Error with Tamiflu

November 18, 2009 | Lebowitz & Mzhen

The FDA has recently published a patient safety alert, reporting medication dosage errors associated with Tamiflu, (for oral suspension), the top doctor prescribed anti-viral flu medication, administered to both adults and children. Our Maryland Pharmacy Misfill Injury Attorneys have been following this prescriber and pharmacy alert report, and how it could effect patient safety in this current H1N1 influenza pandemic.

According to the agency alert, the FDA has received reports that the Tamiflu (oral suspension) dosing instructions for the patient do not match the dosing dispenser. U.S. health providers often write liquid medicine prescriptions in teaspoons or milliliters (mL), while the dosage of Tamiflu is in milligrams (mg). Prescribers and pharmacists have been warned that Tamiflu’s dosing dispenser included in the package has markings only in mg—30, 45, and 60.

The alert recommends that:

Dangerous Drug Abbreviations that Lead to Medical Injury

November 13, 2009 | Lebowitz & Mzhen

In the ongoing topic of medical error and injuries that our Maryland Medication Mistake Lawyers covered earlier this week in a previous blog, the National Coordinating Council for Medication Error Reporting and Prevention (NCCMERP) recommends that in order to help prevent medical error injury and death every year, it is important that the prescribers of medication avoid the use of dangerous abbreviations in prescriptions, including those for drug names and Latin directions for use.

The current NCCMERP list of dangerous abbreviations commonly made by prescibers include:

• Mistaking “µg” for “mg” or milligrams, resulting in an overdose

• “U” is mistaken for zero or a 4, which also results in an overdose. “U” is intended to mean “Units” but with poor handwriting, it can also be mistaken for “cc” or cubic centimeters.

• “Q.D.” means “every day” in Latin. The period after the “Q” is sometimes mistaken for an “I”—and the drug is given “QID” (four times daily), which results in an overdose.

• “T I W” means three times a week. This is often misinterpreted as “three times a day”
• “IU” means International Unit, and is often mistaken for “IV” or intravenous

• “AU, AS, AD” are the Latin abbreviations both ears, left ear and right ear. These are often misinterpreted as the Latin abbreviation “OU” (both eyes), “OS” (left eye), and “OD” (right eye)

The Council also recommends that in order to enhance the accuracy of prescription writing and communications, doctors, nursing and pharmacy staff should:

• Make sure all prescriptions are legible and include notes on medication purpose—like cough, or allergies—maintaining that the proper medication is dispensed.

• All prescription orders should be written in the metric system, except for orders that use standard units like vitamins or insulin. Units should also be written out, rather than abbreviated with “U”

• Medication orders should include the exact drug name, metric weight or concentration, dosage form, with strength and concentration expressed in metric amounts.

• The NCCMERP reports that numerous errors in drug strength and dosage have occurred with the use of decimals—due to the trailing zero (1.0 mg) or the lack of a leading zero (0.1 mg). A leading zero should always be used before a decimal, and trailing zeros should never be used.

Death from Medication Error Leads to Prevention Awareness

November 10, 2009 | Lebowitz & Mzhen

As Maryland Medication Error Injury Attorneys, we have recently read data from the U.S. Food and Drug Administration (FDA) stating that in the United States, 1.3 million people are injured by medication errors every year, with at least one death reported every day.

According to the National Coordinating Council for Medication Error Reporting and Prevention, (NCCMERP), injury from medication error is an urgent, a widespread public problem, that needs to receive far more public attention. The NCCMERP estimates that 98,000 people die annually from medical errors that occur in hospitals—an amount that is greater than deaths from motor vehicle accidents, breast cancer, AIDS, even workplace injuries. Medication error can happen at any point, and result in injury—from communication, distribution, prescribing, dispensing, administering or monitoring.

A medication error is defined by the the NCCMERP as any event that is preventable, and may cause medication misusage or patient harm while the medication is being controlled by the health care professional, consumer or patient. Medication errors can happen in professional practices and during procedures, as well as in the systems of prescribing, ordering, the labeling of a product, packaging, dispensing, education, monitoring, usage, and naming conventions.

The FDA states that common causes of medication error stem from poor communication between doctor, pharmacist, and patient, with unclear product names or suffixes, medical abbreviations or handwriting, poor techniques or procedures, or a lack of understanding of directions for patient usage. Job stress or lack of training or knowledge can also lead or contribute to pharmacy error injury or misfills.

Cardiac Medication Dosing Errors Reported Most Commonly With Infants

October 23, 2009 | Lebowitz & Mzhen

As Maryland Medication Mistake Attorneys, we have been following a recent article from Cardiology Today, revealing that cardiac medication mistakes are reported most commonly with infants—in community hospitals, university hospitals, and pharmacies.

The results of a study showed that diuretics and antihypertensive agents are the most commonly reported drugs that are improperly dosed with infants—frequently prescribed by doctors for pediatric patients with heart disease. According to the article, these drugs have the potential for more widespread use because of neonatal care advances, and the increasing incidence of metabolic syndrome and childhood obesity.

Diuretics and antihypertensive agents are considered by many to be safe, because of their frequent use by doctors, but according to the research, it would be much more beneficial for the physicians, clinicians and pharmacists to have accurate information on the assessments of harm rates, and the groups of infant patients who are at particular risk—to prevent serious medical mistake errors and injury with children.

The most harmful error reports came from reported dosing error of the heart condition drugs: nesiritide, calcium channel blockers, milrinone, digozin, and antiarrhythmic agents.

According to the results from voluntary CV medication error reports that were submitted to a medication error database from the years 2003 and 2004, 50% of the total errors reported occurred in children younger than 1 year of age, and 90% of the error reports occurred in infants younger than 6 months of age.

In the 1,424 causes reported, the most frequent causes of medication error or pharmacy misfills were:

• Human error
• Improper dosing
• Missed or double doses
• Misunderstanding of drug orders
• Mathematical errors which include dilutional errors

ISMP Medication Error Cases and Prevention Checklist

October 9, 2009 | Lebowitz & Mzhen

In a prior post from this week concerning pharmacy error injury, our Maryland Medication Error Attorneys at Lebowitz & Mzhen Personal Injury Lawyers discussed a recent study published by the Institute of Medication Practices (ISMP), and the ongoing problem with drug naming standards in extended release medications.

In this study, the ISMP revealed a series of cases reported to the institute, in which drug name suffix medication mistakes have frequently occurred. This study showed specific case examples in order to establish clearer naming conventions in the industry, and improve comprehensive pharmacist and patient awareness—to prevent pharmacy error injury and misfills in the future.

The ISMP study reported these specific medication mistake cases:

• Physicians often prescribe extended release products without the correct suffix, or with a suffix that does not exist for that particular product.

• In an analysis of 402 prescribing errors published by Medscape Pharmacists, the most common type of error in the study (280 cases, 69.7%) was failure to specify the controlled release formulation.

• The ISMP received reports of cases in which pharmacists dispensed Metadate ER instead of Metadate CD—two different extended release forms of methylphenidate-UCB, a stimulant medicine commonly used to treat ADHD. In one case, a prescription for Metadate CD 20 mg was misfiled at a pharmacy, where the staff dispensed Metadate ER 20 mg.

• Some products have multiple suffixes for different formulations of the same drug. Diltiazem products for example (calcium channel blockers) are used to slow the heart rate and normalize the heart rhythm in hypertension and arrhythmia. The many suffixes for Diltiazem include SR, CD, XR, XT, and LA.

• Electronic prescribing can also lead to medication errors on behalf of the prescriber. In one case, a prescriber electronically selected metroprolol tartrate instead of metoprolol succinate because of choosing incorrectly on his PDA.

According to this report, pharmacists, practitioners, and patients should take extra care when reviewing the different formulations and medication names, especially if the medication is available in more than one dosage form.

The ISMP recommends the following medication error prevention checklist:

Patient Safety Alert: ISMP Reports Medication Error with Drug Name Suffixes

October 6, 2009 | Lebowitz & Mzhen

As Maryland Medication Error Attorneys, we have been following a recent study published by the Institute of Safe Medication Practices (ISMP), about the lack of prescription drug naming standards in extended release medications that lead to pharmacy error injury.

According to the study, although extended release drug formulations provide multiple benefits for many patients, the titles used for many medications are often confusing, and can cause patient error when the same drug is presented with several different oral dosage forms in the suffix.

Extended release drug formulations play an important role in maintaining consistent prescription therapies, by preventing the need for patients to remember to repeat dosages—delivering a steady dose of the medication throughout a specific period of time. The difficulty with many of these medications comes in the name. According to the study, drug manufacturers add suffixes or modifiers to already well-known medication names, to keep awareness of the brand, yet differentiate between the immediate-release counterparts. For example: Wellbutrin SR is a sustained release anti-depressant, whereas Wellbutrin XL is the extended-release version. Same name, different release rate.

Reminder after Reading a Story from Institute for Safe Medication Practices (“ISMP”)

February 20, 2009 | Lebowitz & Mzhen

One of the sources of information that we read regularly is published by the Institute of Safe Medication Practices. Recently, the ISMP wrote about individuals who were using a dosage cap from one over the counter medication, to measure medication from another medication.

When the measuring cups were swapped as described above, the result was that the individual taking the medication received an overdose of medication. Just as a reminder, Maryland medication error attorneys at Lebowitz & Mzhen Personal Injury Lawyers recommend that measuring cups stay with the produce that they are designed to measure so that easily avoidable, but potentially dangerous, errors are avoided.
