The present article is based on “Hydromorphone intended for an adult patient inadvertently administered to an infant”, ISMP Canada Saf Bull 2008;8(6):1–3. From time to time, ISMP Canada invites others to share learning based on local initiatives.
A Canadian study assessing the incidence of medication errors in a pediatric emergency department found prescribing errors in 10.1% of charts reviewed and administration errors in 3.9%.1 The authors cited earlier work by others indicating that preventable errors are significantly more common in the emergency department than in other hospital departments.2,3 This heightened risk in the emergency department is thought to result from the need for medications to be given urgently, which means that many drugs are kept in ward stock. In addition, there is generally no pharmacist review of medication orders originating in the emergency department; patients seen in the emergency department may have only a brief, focused encounter with the physician and nurse before medications are ordered and given; a complete medical and drug history may not be available; physicians and nurses are often caring for several patients at the same time in an environment where interruptions are common; and use of high-alert drugs is common.1,4,5 The authors suggested that of the approximately 50 000 children seen annually in their emergency department, 5000 may be subjected to a medication error, and half of these errors might be clinically significant. Adding to these identified risks for emergency departments in pediatric specialty hospitals is the fact that many Canadian hospitals provide care to pediatric patients alongside adults in the emergency department, which greatly increases the risk of harm associated with an “incorrect patient” error. This risk of harm is compounded when a high-alert medication is involved, as is illustrated by the following case, in which an infant inadvertently received a dose of hydromorphone intended for an adult patient. This incident was highlighted in a recent ISMP Canada Safety Bulletin.6 The current article describes findings from an analysis of the incident and suggests opportunities for pharmacist intervention in the emergency department to reduce the likelihood of medication errors.
A mother brought her 9-month-old infant to the emergency department of a community hospital with fever and symptoms of ear pain. Around the same time, an adult patient who was receiving palliative care, whose surname was similar to that of the infant, presented to the emergency department with uncontrolled pain. She was a patient of the attending physician on duty, who was also a family practitioner in the community. After examining the adult patient, the physician inadvertently picked up the infant’s chart and wrote an order for hydromorphone (Dilaudid) 4 mg to be given orally.
Shortly afterward, the infant’s nurse picked up the chart and reviewed the order. She immediately conferred with another nurse about the appropriateness of the order for an infant. She then approached the physician to ask if he had intended to order the hydromorphone 4 mg. The physician verbally confirmed the order as written.
The nurse retrieved the hydromorphone from the automated dispensing cabinet and performed a double check of the drug and dose with another nurse. She verified the infant’s identification, age, and allergies with the mother before administering the hydromorphone. In response to questioning from the mother, the nurse explained that the medication was ”for pain”. After administering the hydromorphone, the nurse asked the mother what other instructions the physician had given her, at which point the mother indicated that her child had not yet been examined by a doctor.
The nurse realized that an error had probably occurred and immediately informed the physician, who disclosed the error to the mother. Immediate remedial steps were taken, including administration of activated charcoal via a nasogastric tube and administration of intravenous naloxone. The infant was transferred to a regional pediatric referral centre and was discharged the following day.
The facility undertook a root cause analysis of the incident and identified the following possible contributing factors:
The root cause analysis conducted by the hospital identified several themes, all of which present opportunities to enhance safety, including availability of medications, communication, education, and the care processes for pediatric and adult patients.
The following selected recommendations are relevant to pharmacists:
Additional details and recommendations can be found in the full report of this case, published in the ISMP Canada Safety Bulletin.6
The importance of reviewing external reports of errors, such as this one, to assess the potential for local occurrence cannot be overemphasized.7,8 Such reviews provide pharmacists with an opportunity to enhance their leadership role in advocating for safe medication practices within their organizations. Selbst and others9 identified pharmacist involvement in the emergency department as a strategy for preventing medical errors in pediatric emergency medicine, based on success in inpatient care. Idrees and Clements5 noted that “Pharmacists are established members of multidisciplinary teams throughout other areas of the hospital. . . . However the emergency department has been an area that is largely neglected.”
“Incorrect patient” errors represent only one of the types of medication error that can occur in the emergency department. Some additional practical ways in which pharmacists can help to enhance medication safety for pediatric patients in the emergency department include the following:
Ideally, these activities would be conducted by a dedicated emergency department pharmacist. The level of pharmacist involvement in emergency departments in Canadian hospitals is highly variable, however, and service may be limited to one shift or a portion of a shift per day, with limited availability on weekends. Of 126 institutions that responded to the 2007/2008 survey of hospital pharmacy in Canada,11 77 (61%) indicated that pharmacists were assigned to the emergency department. Among respondents, teaching hospitals were more likely to provide this service than nonteaching hospitals (72% vs 58%). The actual number of Canadian emergency departments with dedicated pharmacists is not known, but given US data, it is likely to be substantially lower than this report would suggest. New US survey results of facilities offering emergency medicine residency programs found that 8% of institutions had a dedicated pharmacist in the emergency department 24 h/day, 22% had partial coverage, and 77% had no pharmacist coverage.12 Two previous US studies found dedicated pharmacists in 3.5%13 and 14%14 of hospital emergency departments. In those hospitals where pharmacists are available in the emergency department, orders for pediatric patients, particularly orders for identified high-alert medications, can be given priority for review by the pharmacist before administration. In hospitals without a dedicated emergency department pharmacist, there is opportunity to consider additional supports that can be provided within available resources, as well as opportunities for future implementation.
A key patient safety principle is the need to assess the potential for harm related to the particular populations served by a health care organization; pediatric patients clearly represent a vulnerable patient group requiring special attention. Emergency departments, with high patient turnover and diverse and unpredictable patient needs, have greater medication safety challenges than do inpatient units, and these challenges are magnified for pediatric patients. In a guideline for preventing medication errors in pediatrics, Levine and others15 stated that “Because of their specialized knowledge of medications and their role in the drug distribution process, pharmacists are in a unique position to prevent medication errors and ensure appropriate medication use”. These authors also identified a key role for pharmacists in preventing medication errors in pediatrics as simply “be[ing] available regularly in patient-care areas to serve as a source of information”.15 It is hoped that this overview of a medication-related incident involving a young child and the recommendations that have been suggested for consideration will encourage individual pharmacists in hospital settings to take action to review the management of pediatric patients in their own emergency departments and to identify ways in which they can provide assistance to enhance safe medication practices in this specialty area of the hospital.
