Background Prescribing errors in children are common due to individualization of dosage regimen. It potentially has a great impact especially in this vulnerable population. Objective To determine the prevalence and common types of prescribing errors in a Malaysian pediatric outpatient department and to determine the factors contributing to prescribing errors. Setting Pediatric Outpatient Department and Outpatient Pharmacy at a tertiary care hospital in Malaysia. Method This is a prospective, cross sectional observational study where all new prescriptions received by the outpatient pharmacy from patients attending pediatric out-patient clinic were included for analysis. Descriptive statistics and logistic regression were used to analyze the data. Main outcome measure Frequency, types, potential clinical consequences and contributing factors of prescribing errors. Results Two hundred and fifty new prescriptions with 493 items were analyzed. There were 13 per 100 prescriptions with at least one prescribing error and 7.3% of the total items were prescribed incorrectly. The most common types of prescribing error were, an ambiguous prescription (61.1%) followed by an unrecommended dose regimen (13.9%). Logistic regression analysis showed that the risk of a prescribing error significantly increased when the prescription was written by a house officer (OR 4.72, p = 0.029). Errors were judged to be potentially non-significant (33.3%), significant (36.1%), or serious (30.6%). Conclusion The experience of prescribers is an important factor that contributes to prescribing errors in pediatrics. Many of the errors made were potentially serious and may impact on the patients' well-being.

Background Antihistamines are widely prescribed to children but should be used with caution in young children. Objective To determine the paediatric prescribing pattern of antihistamines with a focus on the off-label prescribing and factors that influence such prescribing. Setting Paediatric wards of a tertiary care hospital setting in Malaysia. Methods The pharmacy-based computer system and medical records were used to collect the required data. Labelling status of each antihistamine was determined based on the information provided in the product leaflets. Main outcome measure Antihistamines prescribed off-label and factors associated with such prescribing. Results Of the 176 hospitalised children aged <18 years prescribed with an antihistamine in the year 2012, 60.8 % received it in an off-label manner. Of 292 antihistamine prescription items, 55.5 % were prescribed off-label. Loratadine (35.3 %) was the most frequently prescribed antihistamine and chlorpheniramine maleate (34.0 %) was the most common antihistamine prescribed off-label. The main reason for the off-label prescribing of antihistamines was prescribing at higher than the recommended dose (30.2 %). Binary logistic regression showed that children aged <2 years (OR 12.65; 95 % CI 2.87-55.67) and the number of medications received (OR 1.14; 95 % CI 1.00-1.29) were significant predictors for the off-label prescribing of antihistamines. Conclusion Prescribing antihistamines for children in an off-label manner was prevalent at the studied locations and warrants further investigation on the consequences of such prescribing.
