Pediatric Weight Errors and Resultant Medication Dosing Errors in the Emergency Department

A retrospective study of 79,000 ED encounters at a children’s hospital and two general hospitals. The intent of the study was to characterize the frequency of weight errors and to determine of the children’s hospital was any better at correcting errors than the general hospitals. The findings were that weight errors were uncommon (0.63% of all weights, as defined by the weight being a new extreme value on the growth chart) in the 3 EDs, but they led to identifiable weight-based medication-dosing errors with the potential to cause harm. The rates of error where similar across hospitals, and it looked like the children’s hospital was slightly better at intercepting errors once they were committed. Common weight errors included the weight in pounds being substituted for the weight in kilograms and decimal placement errors.

Tenfold Medication Errors: 5 Years’ Experience at a University-Affiliated Pediatric Hospital

A study of pediatric inpatient safety reports. From the abstract: “From 6643 medication-related safety reports, 252 10-fold medication errors were identified at a mean reporting rate of 0.062 per 100 total patient days. Morphine was the most frequently reported medication, and opioids were the most frequently reported drug class. Twenty-two reports described patient harm. Intravenous formulations, paper ordering, and drug-delivery pumps were frequent error enablers. Errors of dose calculation, documentation of decimal points, and confusion with zeroes were frequent contributing causes to 10-fold medication error.”

The Effect of an Electronic Health Record–based Tool on Abnormal Pediatric Blood Pressure Recognition

Evaluation of whether provider recognition of abnormal BP (greater than 90th percentile) differed before versus after the introduction of an app that extracts age, sex, height and BP data from the EHR to calculate and track a patient’s BP percentile longitudinally. The app was based on the Substitutable Medical Applications & Reusable Technology (SMART) platform and is available In the SMARTApp Gallery. Examining ~79,000 records of outpatients (primary care, endocrinology, cardiology, nephrology clinics), of which ~3500 had elevated blood pressure, showed that abnormal BP was recognized in 4.9% of visits before the app was available and 7.1% of visits afterwards. The app was used in 13% of encounters where an elevated BP was present; significantly, when the app was used, recognition of elevated BP was much higher (OR 3.17, CI 2.29-4.41).

Automated Identification of Implausible Values in Growth Data from Pediatric Electronic Health Records

Reports the development of an automated method for identifying implausible values in pediatric EHR growth (weight and height) data, tested via data points collected in the primary care environment on over 280,000 patiets. The method compares each measurement’s z-score to a weighted moving average of prior measurements. The method had a sensitivity of 97% and a specificity of 90% for identifying implausible values compared to physician judgment, and identified almost all simulated errors.

Recognition of Elevated Blood Pressure in an Outpatient Pediatric Tertiary Care Setting

Another study suggesting we are not very good at officially diagnosing elevated blood pressure in children when the record shows BP readings that are repeatedly elevated. Of 29,000 records retrospectively reviewed, only about 1 in 6 of those with repeatedly high blood pressure values were diagnosed in the encounter diagnoses or problem list.
