1 Preventing Medication Errors in Pediatric and Neonatal Patients

2 Learning Objectives Discuss common medication errors that occur in pediatric and neonatal patient care Describe error reduction strategies for the pediatric and neonatal populations Explain limitations of automated medication error reduction devices in these populations Describe the role of the interdisciplinary team in preventing medication errors

3 Adverse Drug Events ADEs are injuries that result from drug use
May be preventable or nonpreventable Potential ADEs result from medication errors with potential for harm but: Are intercepted before reaching patient, or Reach patient but do not cause harm .

4 Incidence of Adverse Drug Events
Medication error rate: pediatric error rates approximately equal to adult error rates Errors in pediatrics are 3 times more likely to be associated with a potential ADE Neonatal ICU: patient group with highest error and potential ADE rate 74% of errors and 79% of potential ADEs occur in ordering phase Fortescue E, et al. Pediatrics. 2003;111(4 pt 1):722–9. Kaushal R, et al. JAMA. 2001;285:2114–20.

5 Reasons for Increased Risk
Different and changing pharmacokinetic parameters Lack of pediatric formulations, dosage forms, guidelines Calculation errors Inconsistent measurement of preparations Problems with drug delivery systems

6 Pediatric and Neonatal Pharmacokinetics
One size doesn’t fit all Preterm neonates (<36 weeks’ gestation) Full-term neonates (birth to 30 days) Infants (1–12 months) Toddlers (1–4 years) Children (5–12 years) Adolescents (>12 years)

7 Pediatric and Neonatal Pharmacokinetics
Do not use the terms interchangeably Discuss patients in terms of age and weight to provide more accurate kinetic profile Difference between adolescent and preterm neonate drug dose: potentially 100-fold Referring to a patient as being a child is open to interpretation. Be specific (i.e., a 4 year old weighing x kg). This provides a more accurate picture of the child in terms of their pharmacokinetic profile. 7

8 Reasons for Increased Risk
Different and changing pharmacokinetic parameters Lack of pediatric formulations, dosage forms, guidelines Calculation errors Inconsistent measurement of preparations Problems with drug delivery systems

9 Lack of Pediatric Formulations
May lead to: Crushing tablets Opening capsules and adding to food or beverage Utilizing IV formulations for oral use Using ophthalmic preparations in the ear Giving oral anticonvulsants rectally Compounding extemporaneous products

10 Lack of Pediatric Formulations
Pitfalls of altering adult formulations Insufficient data to support practice Expiration dating of compounded formulation Unknown bioavailability Extemporaneous compounding errors

11 Lack of Pediatric Formulations
Barriers to commercial availability Complications of testing in pediatric patients Concerns involving informed consent Recruitment problems (e.g., too few patients) Determining which pediatric subset to test Market limitations Cost of testing may outweigh expected market Market share typically less than in adult market Less financial incentive to manufacturers for most disease states Often times, people will turn to investigational studies when they have no other options for treating a disease state. 11

12 Attempts to Overcome Barriers
American Academy of Pediatrics Shared responsibility to conduct research in children to support rational drug therapy in children Amendments to the Food, Drug, and Cosmetics Act Pediatric Research Equity Act (PREA) and Best Pharmaceuticals for Children Act – 2003, 2007 Manufacturers of drugs or biologics that submit an application to market a new active ingredient, indication, dosage form, dosing regimen, route of administration must include a pediatric data assessment Provided 6-month exclusivity extension Provided funding for research of “orphan” therapies These acts are meant to increase pediatric testing and data for drugs. Waivers are allowed to the PREA, however, the 2007 version added documentation requirements as to why a pediatric formulation could not be manufactured 12

13 Sources of Errors Confusion between adult and pediatric formulations
Confusion among oral liquid concentrations “Look-alike” and “sound-alike” packaging and names Multiple dosing styles

14 Adult Versus Pediatric Formulations
Different concentrations Different volumes Should be stored in separate locations to avoid errors Within the pharmacy On nursing units

15 Oral Liquid Concentrations
Multiple concentrations of same product Fatal overdoses occur annually Example of dangerous situation Available liquid acetaminophen products: 100 mg/mL Infant drops 160 mg/5 mL Children’s liquid 167 mg/5 mL Adult extra strength Ask parent to give a child 5 mL of Tylenol Child is 4 years old Parents only have drops; give 5 mL of drops (500 mg) Correct dose should have been 160 mg

16 Look-Alike, Sound-Alike
Medication names Medication packaging Confusion between IV and oral products This problem has increased in pediatrics as practice of using IV medication for oral administration has increased

17 Additional Information on Look-Alike and Sound-Alike Medications and Packaging Available in Slide Deck for Chapters 6 and 7

18 Multiple Dosing Styles
Daily dosing versus every 6 hours Acetaminophen 10–15 mg/kg/dose q 6–8 hr Ampicillin 100–200 mg/kg/24 hr divided q 6hr Practitioners must read the fine print Watch your units! mcg/kg/min versus mg/hr versus mcg/kg/hr Electrolyte dosage mEq versus mg versus grams

19 Reasons for Increased Risk
Different and changing pharmacokinetic parameters Lack of pediatric formulations, dosage forms, guidelines Calculation errors Inconsistent measurement of preparations Problems with drug delivery systems

20 Calculation Errors Misuse of decimals Ordering a dose in volume
Wrong Right .1 mg 0.1 mg 1.0 mg mg Way to remember: if the decimal is not seen, 10-fold error might be made Ordering a dose in volume Creates ambiguity if medication is available in several different concentrations

21 Calculation Errors Single dose divided by frequency
3 mg/kg every 8 hours Example: 10 kg patient Correct: 30 mg every 8 hours Incorrect: 30 mg daily divided every 8 hours (10 mg every 8 hours) Not dividing daily dose by frequency 6 mg /kg/day divided every 8 hours Correct: 20 mg every 8 hours (60 mg total daily dose) Incorrect: 60 mg every 8 hours

22 Calculation Errors Errors in unit conversion
Miscalculation of body surface area Misplaced decimals Compounded errors: 10-fold errors Errors calculating drip rates Weight-based errors Using wrong weight or old weight Expressing weight as lb (wrong) instead of kg (right)

23 Insulin Dilution For insulin doses ≥5 units
May use the 100 units/mL concentration For insulin doses <5 units Dilute insulin in pharmacy to 10 units / mL Only send individual, patient-specific doses to nursing unit Vials of diluted insulin should not leave pharmacy A 1 mL tuberculin syringe is used to administer

24 Reasons for Increased Risk
Different and changing pharmacokinetic parameters Lack of pediatric formulations, dosage forms, guidelines Calculation errors Inconsistent measurement of preparations Problems with drug delivery systems

25 Oral Measuring Devices
Oral medications more likely to be dispensed in bulk and not in unit of use 3 out of 4 households still use kitchen teaspoons for measuring* Pre-packaged dispensing cups or droppers Mistaken for whole doses versus graduated dosing Various calibration units on syringes Varies on different syringe sizes *Institute for Safe Medication Practices. Safety briefs. ISMP Medication Safety Alert! February 26, 1997;2:1.

26 Rule of 6 The “Rule of 6” is an equation used to calculate the amount of drug to add to 100 mL of IV fluid so that an infusion rate of 1 mL/hr will deliver 1 mcg/kg/min 6 x weight (kg) = amount of drug (mg) 100 mL of solution

27 Concerns With Rule of 6 Not consistently used
Calculations and mixing may be completed at bedside without pharmacy double check Typically done with critical care, high-risk drugs Dosage adjustments can result in fluid overload Error risk compounded when double or triple concentrating infusions Drug waste

28 The Joint Commission and the Rule of 6
2002: National Patient Safety Goal (NPSG) requiring standardization and limitation of concentrations of high-alert medications in all patients Hospitals were allowed to apply for exemption for Rule of 6 By December 31, 2008, all hospitals must comply with standardization

29 Reasons for Increased Risk
Different and changing pharmacokinetic parameters Lack of pediatric formulations, dosage forms, guidelines Calculation errors Inconsistent measurement of preparations Problems with drug delivery systems

30 Administration of Enteral Fluids
Enteral pumps may not be able to deliver small enough volumes to neonates Parenteral syringe pumps have been used instead Increases risk for accidental IV administration To prevent accidental IV administration of enteral products Trace tubing to point of origin prior to connecting tubing Label tubing, administration sets, pumps Use non-Luer feeding tubes Will connect only with oral syringes

31 Strategies for Medication Error Reduction

32 Strategies With Highest Error Prevention Potential in Pediatric Patients
Improved communication among physicians, nurses, and pharmacists Unit-based clinical pharmacists making rounds with the health care team Use of computerized prescriber order entry (CPOE) with decision support Fortescue E, et al. Pediatrics. 2003;111(4 pt 1):722–9.

33 Staff Competencies Require math competencies for all staff
Develop competencies for entire team before new service is implemented Provide resources for maintaining competency for pediatric and neonatal pharmacology Ensure competency on all staffing shifts

34 Patient Information Provide patient age and date of birth
Decreases risk of confusing age in years versus months Weight and height in metric measures only Patient’s medication history Include concentration of all medications Record doses in milligrams, not in volume Specifically ask about common OTCs Acetaminophen, ibuprofen, vitamins

35 Know Your Own Height and Weight
Provides a frame of reference Know your height in centimeters Know your weight in kilograms

36 Reduction of Calculation Errors
Establish reliable method of providing current patient weight in kg to the health care team Require calculated dose and dose per weight (i.e., mg/kg) on each order Acetaminophen 100 mg (10 mg/kg) every 6 hours by mouth Exceptions Vitamins, topicals, other medications not requiring weight-based dosing Require independent double check of dosing calculations

37 Reduction of Calculation Errors
Use pre-calculated dose sheets Emergency medication sheets Commonly used medications Standardize dosing and concentrations IV drip rates or concentrations Recipes and strengths for extemporaneous compounds Provide pediatric references in ordering, dispensing, and administration locations Encourage rounding to whole numbers when possible

38 Reduction of Calculation Errors
Include warnings for potentially low or high doses in the pharmacy and CPOE systems Appropriately use decimal points Utilize leading zeros: (right) (wrong) Do not use trailing zeros: (right) (wrong)

39 Reduction of Prescribing Errors
Verbal orders Only for emergent/urgent situations Always write down order and read back Not allowed when the prescriber and chart are available Not accepted by pharmacy without written confirmation (prescription faxed/sent prior to dispensing) Limit to formulary drugs Received only by those authorized by the hospital to do so Spell drug names and pronounce numeral digits Fifty, Five Zero Never accept verbal chemotherapy orders Have order signed by prescriber as soon as possible Cohen MR. Medication Errors. Causes, Prevention, and Risk Management; 11.1–11.16.

40 Reduction of Prescribing Errors
Write directly into patient’s chart Avoid abbreviations Do not use u for unit; spell out “unit” U can be misread as a zero 10u can be misread as 100 Do not use cc; use mL cc can be misread as 00 1cc has been interpreted as 100 Include patient weight in each order

41 Reduction of Dispensing Errors
Standardize concentrations Use one consistent formula or standard concentration Use commercially available unit of use preparations whenever feasible Have pharmacy prepare all IV admixtures and oral liquid preparations Independently double check prior to dispensing

42 Reduction of Administration Errors
Oral liquids Dispense in unit of use Oral syringes Dispensing bottles Do not administer oral liquids with IV syringes Syringe tips are a choking hazard Only utilize dosing graduated cups or oral syringes Oral syringes have caps that are harder to remove

43 Reduction of At-Home Administration Errors
Dispense appropriate measuring device with each prescription and refill Review dosing instructions with caregivers Suggest a “1 caregiver” administration policy Prevents overdoses by well-meaning multiple caregivers administering doses Ask caregiver to demonstrate administration technique Including measuring doses

44 Medication Safety in Pediatric Emergencies
Broselow tape “Measuring tape” placed next to a supine child Based on child’s length, tape estimates child’s weight Broselow tape and code medication concentrations must match within a facility Educate staff on proper use and limitations of using tape Utilize most recent tape version Limitations for Broselow tape Incorrect positioning next to child Doses may be expressed in volume Provides directions to make infusions with non-standard concentrations Broselow tape utilizes height or length to determine doses in an emergency. Realizing that weight and age may not be available during an emergency situation in a pediatric patient. Color coded 44

45 Section of Broselow Tape

46 Medication Safety in Pediatric Emergencies
Provide age-appropriate code trays Adult, pediatric, neonatal Set appropriate par levels Provide pre-printed “code sheets” Weight-based dosing algorithms Ideally, print individualized code sheets for each patient Establish verbal order procedures Involve a pharmacist in ED medication use

47 Reducing Errors in the Pediatric OR
Within therapeutic classes Reduce number of drugs and concentrations Label all medications placed on and off sterile field including: Drug name Concentration/strength Date and initials of person preparing The Joint Commission NPSG Segregate neuromuscular blocking agents from other medications

48 Reducing Errors in the Pediatric OR
Add required medications to surgeon’s preference cards or pre-printed order forms Avoids verbal orders or faxes from OR Standardize medications and concentrations for same procedures Advocate for weight-based preparation of anesthesia supplies Provide standardized trays Communicate information about perioperative medication use to postoperative care team

49 Pre-Procedure Sedation
Often prescribed for administration at home prior to arrival at physician’s office Chloral hydrate and benzodiazepines most common American Academy of Pediatrics Children should not receive sedatives without supervision and monitoring by skilled medical personnel with appropriate resuscitation equipment

50 Automation Automated Dispensing Cabinets (ADC)
Bar Code Point of Care (BPOC) Computerized Prescriber Order Entry (CPOE) “Smart” Infusion Pumps

51 Role of Automation in Pediatric and Neonatal Services
Safety CPOE: Ability to check prescribed doses against patient weight ADCs make dosages available for emergent or after hours use Bar coding checks for correct patient, drug, dose, dosage form, and time at point of drug administration Smart infusion pumps allow for safety checks on standard concentrations prior to infusion

52 Pitfalls of Automation in Pediatric and Neonatal Services
CPOE Data are only as accurate as information entered Correct patient weight may not be in system Labels may not be appropriate for pediatric dosage forms Bar code reading Difficult on pediatric dosages Difficult on pediatric and neonatal arm/leg bands

53 Pitfalls of Automation in Pediatric and Neonatal Services
ADCs Medications requiring further preparation or measurement by the nurse may be stored in ADC Drugs may be obtained before pharmacist review (override) When accessing one particular drug, nurse may have access to other drugs “Smart” infusion pumps (use a drug library to provide alerts if pump is potentially misprogrammed) Systems may not allow for hundredths decimal place Doses in small total volumes may not account for volume needed to fill tubing Infusion rates can be checked only if IV drug is a standard concentration
