Results of Pediatric Medication Safety Survey (Part 2): Comparing Data Subsets Points Out Areas For Improvement
Preventing medication errors in pediatric patients poses unique challenges for healthcare providers. Pediatric patients are three times more likely than adults to experience a harmful medication error1 or adverse drug reaction2 given their size, immature renal and hepatic functions, inability to communicate symptoms of adverse effects, and other risk factors. Children are particularly vulnerable to errors if they are younger than 2 years, in the neonatal intensive care unit or emergency department, receiving chemotherapy or other IV medications, or if their weight has not been documented.3
In March and April 2015, ISMP conducted a survey to learn about the frequency with which healthcare providers employ key error-prevention strategies and “best practices” when caring for pediatric patients. We received responses from 1,463 clinicians, mostly nurses, pharmacists, and physicians, working in both inpatient and outpatient settings.
In our June 4, 2015 newsletter, we presented the aggregate survey results as Part 1 of our analysis. We also compared the findings to a similar survey we conducted 15 years ago. In Part 2, we compare subsets of the survey data based on the participants’ practice site and professional designation (results in Table 1). Although the results confirm some logical assumptions about the implementation of medication safety best practices in pediatrics, there are areas of exception worth noting.
Practice Site Comparisons
General practices. The majority of survey participants are weighing patients only in metric units and documenting weights using only the metric system. Most participants in pediatric hospitals (87%) and adult-pediatric hospitals (76%) said they always express doses of liquid medications in the metric system, but only 67% of outpatient facilities reported the same. The lowest scoring general strategies included standardizing and limiting the concentrations and dosage strengths of high-alert medications, particularly in outpatient facilities (60%), and separating adult and pediatric medications in storage areas, particularly in adult-pediatric hospitals (49%).
Prescribing practices. Best practices associated with prescribing pediatric medications were reported in higher frequency in both inpatient and outpatient facilities that treat only pediatric patients. Adult-pediatric hospitals tended to report lower compliance. However, approximately one-third or more of all participants did not report full compliance for any prescribing best practices, suggesting the need for improvement.
For example, prescribers consistently include both the basis for the dose (e.g., mg per kg) and the calculated amount per dose in medication orders or prescriptions in just 40% of pediatric hospitals, 41% of outpatient facilities, and 33% of adult-pediatric hospitals. Prescribers consistently order pediatric liquid medication doses in metric doses, not volume alone, in only about half of all participant facilities. The patient’s weight in kg or g is entered into the computerized prescriber order entry (CPOE) system before medication orders are entered in 61% of pediatric hospitals, 63% of outpatient facilities, and 54% of adult-pediatric hospitals. Dose range checking software was reported by 65% of pediatric hospitals, 64% of outpatient facilities, and 55% of adult-pediatric hospitals. Among practice sites where parenteral nutrition (PN) or other complex electrolyte solutions were prescribed, only about two-thirds reported that prescribers order the total amount of each ingredient as dose/kg/day (e.g., mg/kg/day, mcg/kg/day) for younger children, and only about half reported ordering the total amount of each ingredient per day for older children.
Dispensing practices. Overall, pediatric hospitals reported higher frequencies of implementing best practices associated with dispensing medications than adult-pediatric hospitals or outpatient pediatric facilities.
Automated compounding devices are used to prepare solutions much more often in pediatric hospitals (84%) and adult-pediatric hospitals (71%), compared to outpatient facilities (46%). Pediatric hospitals also reported higher compliance with dispensing oral liquid doses in cups or oral syringes and more consistent implementation of entering PN or other complex electrolyte solutions into the pharmacy computer and compounding software exactly as each ingredient is prescribed. Outpatient facilities scored as high as or higher than pediatric hospitals and adult-pediatric hospitals with requiring entry or verification of the patient’s age before medication orders are entered in the pharmacy computer.
Of particular concern is that only 41% of pediatric hospitals, 43% of adult-pediatric hospitals, and 19% of outpatient facilities require the components of pediatric/neonatal compounded sterile preparations to be verified by a pharmacist prior to adding them to a solution. The lowest scoring practices for all practice sites were associated with the pharmacist’s time spent on units; for example, a clinical pharmacist is consistently available in patient care areas in just 16% of adult-pediatric hospitals, 24% of outpatient facilities, and 30% of pediatric hospitals.
Administration practices. Participants from pediatric hospitals reported a higher frequency (78%) of requiring nurses to undergo specialized training and to demonstrate clinical competency than adult-pediatric hospitals (58%) and outpatient pediatric facilities (65%). Pediatric hospitals also reported higher compliance with making available specially designed oral syringes to administer oral/enteral liquid medications. Both pediatric hospitals and outpatient facilities reported higher compliance with providing patient-specific doses of emergency drugs and commonly used medications on each pediatric patient’s chart.
Although smart pumps with an active drug library were consistently used to administer pediatric solutions containing high-alert medications in 59% to 63% of all work places, outpatient facilities were more likely to require an independent double check of high-alert medication solutions to verify the patient, drug, strength/dose, line attachment, and smart pump settings, than adult-pediatric hospitals or pediatric hospitals. Bedside barcode medication administration was fully implemented for medications and breast milk feedings in 58% and 48%, respectively, of pediatric hospitals, in 69% and 47% of adult-pediatric hospitals, and 43% and 13% of outpatient facilities.
Practitioner Type Comparisons
Prescribing practices. Physicians and nurses tended to report higher (and similar) rates of full compliance with prescribing best practices, while pharmacists—who see prescribed orders daily—tended to report lower compliance. For example, physicians and nurses reported 41% and 45% compliance, respectively, with prescribers including the mg/m2 or mg/kg dose and the final calculated dose with pediatric drug orders, but pharmacists reported just 26% compliance with the practice. More than two-thirds of physicians and nurses reported that the pediatric patient’s weight must be entered or verified in the CPOE system before medications can be entered, but only 43% of pharmacists agreed. Seventy-six percent of physicians and nurses reported full implementation of prescribing each ingredient of PN and other complex electrolyte solutions as dose/kg/day for younger children, while only 53% of pharmacists agreed.
Dispensing practices. More pharmacists reported full compliance than nurses or physicians for several dispensing practices, which may be due to professions outside of pharmacy not being aware of exactly what the pharmacist does. But one practice stands out: 74% of pharmacists reported full compliance with dispensing patient-specific doses of liquid oral/enteral medications for pediatric patients in cups or oral syringes; only 15% of nurses reported that the pharmacy dispenses these medications in cups or oral syringes.
Pharmacists did report less compliance than the other two professions for some specific tasks, suggesting the possibility that nurses and physicians may rely on pharmacy to complete these tasks without realizing they are not being carried out. Examples include:
- Available and enabled dose range checking software in the pharmacy computer
- Barcode scanning to verify the ingredients of pediatric IV and oral liquid doses during preparation
- Verification of components and amounts of pediatric and neonatal compounded sterile preparations prior to adding them to a solution
- Providing specialized training and requiring demonstrated clinical competency before pharmacists/technicians can prepare or check pediatric parenteral solutions
Administration practices. Nurses were much more reluctant than physicians or pharmacists to report full compliance for most of the best practices associated with drug administration, although they frequently indicated full compliance for prescribing and dispensing best practices. Even if we combine full compliance with partial compliance frequencies for comparison, nurses still reported lower compliance than pharmacists or physicians for many administration best practices. The most significant differences included:
- Use of a smart pump with an enabled library to administer pediatric IV parenteral solutions
- Conducting an independent double check of a solution against the medication administration record or order to verify the patient, drug, strength/dose, line attachment, and pump settings
- Providing specialized training and requiring demonstration of competency for nurses who administer medications to pediatric patients
- Availability of oral syringes in patient care units to administer all liquid oral/enteral medications
- Barcode scanning at the bedside for patient identification and medication verification
- Barcode scanning for patient identification and verification of breast milk prior to feeding
Patient Care Unit Comparisons
Pediatric inpatient units. When comparing implementation of medication safety best practices among different patient care units, we found that pediatric inpatient units in a pediatric hospital scored higher than pediatric units in a general hospital. There was one exception: entry or verification of the patient’s age before entering or verifying orders in the pharmacy, for which 60% of pediatric units in general hospitals reported full implementation compared to 47% of pediatric units in pediatric hospitals.
Emergency departments (EDs). When comparing practices in EDs, we found that the best practices were reported most frequently in pediatric hospital EDs than in EDs in general hospitals. But again, there was one exception: availability and activation of dose checking software in the CPOE system—there was 53% full implementation in EDs in general hospitals, compared to 41% in EDs in pediatric hospitals.
Oncology units. Participants who worked in pediatric outpatient oncology units reported a higher frequency of implemented practices associated with prescribing and drug administration. But implementation of dispensing best practices was reported more frequently in inpatient oncology units, especially practices associated with preparing PN and other complex electrolyte solutions or sterile compounds, preparing doses of liquid oral/enteral medications in oral syringes or dose cups, and use of barcoding to verify the ingredients.
Neonatal nurseries. When comparing the different units providing neonatal care, those working in level II nurseries reported a higher frequency of implementing best practices in most areas except the presence of a clinical pharmacist; 30% of participants who worked in level III or IV nurseries reported a consistent clinical pharmacist on the unit, compared to 21% in level II nurseries.

Overall, ISMP’s survey shows that improvements are still needed to protect pediatric patients from harmful medication errors. And all facilities and units that treat pediatric patients have something to learn from each other.
Not unexpectedly, pediatric hospitals rank higher in implementing many best practices associated with medication use than hospitals that treat both adult and pediatric patients and outpatient pediatric facilities. But the survey reveals some notable exceptions. It also uncovers areas of variation between practitioners and patient care units, including the fact that physicians, nurses, and pharmacists report different levels of compliance with best practices, which offers insight into how each discipline views their own and others’ contributions to pediatric medication safety.
ISMP hopes that all healthcare providers who care for pediatric patients will assess their practices, using Table 1 as a guide, and develop a plan to improve implementation. Although partial adoption of the surveyed best practices is safer than none at all, any variance in practice can lead to an error—particularly if staff expect a strategy to be in place when it is not. Providers should examine their exceptions and settle for nothing less than full compliance in order to better protect children receiving medical care in any setting.
