Unit 8 Medication Safety Reflection

[Instructor Name]

[Date]

The child, staff and event are composite; values are bracketed where illustrative, no dose reached the child, and the facility's reporting process governs real events.

The Event

[Jayden], composite, 7, slight for his age, came up from the emergency department with a skin abscess needing IV antibiotics. At triage his weight was recorded as [48] in the kilogram field; the scale had displayed pounds. The antibiotic order was calculated from 48 kg. Nine hours later, during a supervised medication check, I was preparing the dose alongside my assigned nurse. The volume looked large to me, larger than the doses I had drawn up for teenagers. I looked at Jayden, who was small, and I looked at the weight. For about thirty seconds I said nothing. Then I said, "Does 48 kilograms seem right for him?" My nurse stopped, looked, and agreed it did not. He was reweighed at [21.8] kilograms. Pharmacy and the prescriber were called, the order was corrected, and the event was entered in the facility's reporting system as a near miss.

The System

Using the Swiss cheese model, in which an error causes harm only if gaps in successive safeguards happen to align (Reason, 2000), I mapped four layers:

1. Weighing at triage: a scale that could display pounds, in a department that also sees adults. Failed.

2. Entry into the record: a kilogram field with no alert for a weight far above the expected range for a seven-year-old. Failed.

3. Ordering and pharmacy verification: the dose was within the drug's per-kilogram range, so a weight-based check passed it. Failed, because the check trusted the weight.

4. Bedside preparation: a person comparing the number with the child. Held.

Every check after triage checked the arithmetic, and the arithmetic was right; only a person looking at the child could see that the starting number was wrong.

Weight-based calculation errors are a known source of medication error in children, and errors in the weight itself spread into every dose calculated from it (Conn et al., 2019).

Kilograms Only, and the Reason

The fix that would have closed the first hole is simple: scales in pediatric areas that display kilograms only, and weights recorded only in kilograms. Removing the option to weigh in pounds removes the chance of entering one in the wrong field. A record that alerts when a weight is far outside the range for age would close the second (Perry et al., 2022).

The Writer

Why did I wait thirty seconds? I was a student next to an experienced nurse, the order had passed pharmacy, and I assumed someone would have caught a problem by now. I also did not want to sound as though I were accusing anyone. Those are exactly the reasons people stay silent in front of errors. The thirty seconds did no harm this time, because the dose had not been given, but on a busier day the nurse could have hung the bag while I was still deciding. What made me speak was the mismatch between the number and the child. That is the habit I want to keep: look at the patient, not only the paperwork.

What My Nurse Did Next

My nurse did three things I want to copy. She stopped the preparation completely rather than finishing it and checking later. She thanked me in front of the pharmacist, which made it easier for me to speak next time. And she called the emergency department charge nurse that afternoon, not to blame the triage nurse, but to ask whether their scale could be locked to kilograms. A good response to a near miss looks forward to the next child, not back at the person who made the entry.

Reported Before It Was Reflected On

The event was reported the same day, before I wrote this. A near miss reported is a chance for the system to fix the hole; one that is only reflected on stays a personal lesson.

What I Will Do

Before preparing any pediatric dose, I will check that the weight is in kilograms, that it fits the child I see and that it was measured on this admission. If a number does not fit, I will say so in the first five seconds, in a question: "Can we check this weight?" This connects to my third objective for the rotation, and I will record each check in my preparation notes.

What I Am Still Unsure About

I do not know how often weights are wrong in the records I see, because I only noticed this one. I would like to know whether the unit audits weights, and whether reporting this near miss led to a change in the emergency department's scales.
