new YORK (Reuters Health) – the use of drugs in

dose 10 times higher or lower than the indicated is a

threat to pediatric patients.

“Given that the rates quoted are of voluntary reports

and anonymous, unlike the existing error figures

physicians, is difficult to determine what the actual incidence”, said

Dr. Conor McDonnell, of the Hospital for sick children of

Toronto, Canada.

“Even so, I am not surprised to have found that amount of

dosing errors because pediatric patients are

especially exposed to such a risk”, he added.

Large variations in age, weight, dose and practices not

authorized favour the Commission of these errors, although few

studies had tried to identify them.

McDonnell and Catherine Doherty doctors analyzed the

errors in dosage that had identified reports

volunteers for five years to determine what classes of

drugs occurred more frequently and in what circumstances

these misdeeds.

252 Errors were recorded in the period 2004-2009, with the

(178 overdose and 74 subdosis) doses of 6,643 reports on

Security associated with the use of medications, which reveals a

upward trend. The average rate was 0,062 each 100

patient per day.

The most common errors occurred with the indication and the

Administration of drugs. Only 123 252 errors are

detected before they affect the patient.

Opioid analgesics were the pharmacological class with

which were committed more errors (18 per cent of all the

dosage errors), while morphine was the

only use more errors with medication (11 per cent of

all errors), followed by antimicrobials and in third

place, anticoagulants (exclusively heparin).

For these three classes of medicinal products, the origin

common error was in the calculation of the dose (44 cases)

and the incorrect administration device programming

(22 cases). The Elimination of the alarms and limits

suggested allowed that 25 of those mistakes were committed.

Opioids were the most reported drug class in

the 22 reports on damage to patients, while the

morphine was more specified medication.

“Despite the number of errors identified in the

study, no deaths were recorded or morbidities in the long

period”, said McDonnell.

With these results, the authors prepared a list with

more than two dozen recommendations to reduce the frequency

of errors in dosage in its Center.

McDonnell considered that “the most important factors still

being the recognition and identification of errors. “Not

all centres will commit the same mistake with them

drugs; therefore, it is important that centres

identify which medications are associated with errors and

local damage, and plan their interventions”.

“Having said that, opioids (notably morphine and

hydromorphone) are the drugs that most errors are

they are committed and take measures such as the use of fixed-dose sets

according to weight, clinical pharmacologists have of

guard, detect stress of clinical tasks and the

human factors (stress, distraction, fatigue) that favor the

appearance of these errors, like thus also take into account the

mistakes that can be made with intravenous administration

of opioids via the use of bombs, will reduce the frequency and

the results of medical errors associated with the

10 times greater or lesser drug dosage”,

added.
