Insights
Tenfold medication errors in children are dangerous. Their incidence varies greatly depending on how they are detected, with spontaneous reporting underestimating the true rate, especially during resuscitations.
Area of Science:
- Pediatric Pharmacology
- Medication Safety
- Clinical Pharmacy
Background:
- Tenfold errors in pediatric drug dosing pose significant life-threatening risks.
- The full extent and characteristics of these critical medication errors remain underexplored.
Purpose of the Study:
- To determine the incidence and nature of tenfold medication errors in pediatric patients.
- To evaluate how different methods of error detection impact the identification of these errors.
Main Methods:
- Analysis of medication incident reports submitted to a hospital's Medication Incident Committee.
- Chart audits of 1532 patients in the emergency department (ED).
- Prospective study of medication errors during simulated resuscitation events in the ED.
Main Results:
- Twenty tenfold errors were reported via incident reports (incidence: 1 per 22,500 prescribed doses).
- Chart audits identified two tenfold errors among 1678 orders.
- Four tenfold errors were found in 125 drug orders during eight mock resuscitations.
Conclusions:
- The detected incidence of tenfold errors in pediatrics is highly dependent on the detection method employed.
- Spontaneous reporting significantly underestimates the occurrence of these errors.
- Resuscitation scenarios may present a particularly high rate of tenfold medication errors.
Background:
Tenfold errors in calculation of paediatric drug doses are often life threatening. The magnitude and characteristics of this phenomenon have not been fully described.
Objectives:
The objective of this study was to describe the incidence and nature of paediatric tenfold errors and to describe the effect of different detection approaches on the detection of such errors.
Methods:
To evaluate the incidence of tenfold errors, data were collected from three different studies on medication errors all conducted at a large tertiary care paediatric hospital: (i) a study investigating medication event reports to the hospital's Medication Incident Committee; (ii) a study auditing the charts of 1532 patients in the emergency department (ED) and; (iii) a prospective study of medication errors occurring during mock code resuscitations in the ED.
Results:
In the first study, 20 tenfold errors were reported during the surveyed period. Almost all errors were prescribing errors. The calculated incidence was 1 per 22 500 doses prescribed. In chart auditing study in the ED, two tenfold errors where found in 1678 orders. In the prospective study, four tenfold errors were identified in eight mock resuscitations (125 orders for drugs).
Conclusion:
The incidence of tenfold errors in paediatrics varies dramatically when different detection approaches are used. The rate of tenfold errors may be especially high in resuscitation situations and is underestimated by spontaneous reporting.

Types of Errors: Detection and Minimization
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
Systematic or...
Systematic Error: Methodological and Sampling Errors
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...
Accuracy and Errors in Hypothesis Testing
In hypothesis testing, the probability of making a Type I error, denoted as α, is commonly set at 0.05. This significance level indicates a 5% chance...

Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...
