Aim: Studies on frequencies of manipulated medicines in paediatric care are common, but there is little knowledge of experiences of pharmacists and registered nurses in this area. The aim of this study was to explore registered nurses' and pharmacists' reasoning in the manipulation of medicines to paediatric inpatients., Methods: Semistructured interviews with twelve registered nurses and seven pharmacists were performed at a Swedish paediatric university hospital. The interviews were transcribed verbatim and analysed using content analysis., Results: Four major categories emerged from the analysis of the interviews: medicines management, knowledge, consulting others and organisation. Medicines management involved the process of drug handling, which is prescribing, reconstitution or manipulation and administration. Knowledge concerned both the knowledge base and how healthcare personnel seek information. Consulting others involved colleagues, registered nurses and pharmacists, between registered nurses, pharmacists and physicians and between registered nurses, pharmacists and caregivers. Organisation covered documentation, time and working environment., Conclusion: Both pharmacists and registered nurses stated that manipulation of medicines to paediatric patients was often necessary but felt unsafe due to lack of supporting guidelines. Pharmacists were natural members of the ward team, contributing with specific knowledge about medicines and formulations., (© 2023 The Authors.

Aim: To explore the incidence and characteristics of inpatient neonatal adverse events in a Swedish setting., Methods: A retrospective record review, using a trigger tool, performed by registered nurses and a neonatologist, at a University Hospital. The identified adverse events were categorised by, for example, preventability, severity and time of occurrence., Results: A random selection of 150 admissions representing 3531 patient days were reviewed (mean [SD] birthweight 2620 [1120]g). Three hundred and sixty adverse events were identified in 78 (52.0%) infants, and 305 (84.7%) of these were assessed as being preventable. The overall adverse event rate was 240 per 100 admissions and 102.0 per 1000 patient days. Preterm infants had a higher rate than term infants (353 versus 79 per 100 admissions, p = 0.001); however, with regard to the length of stay, the rates were similar. Most adverse events were temporary and less severe (n = 338/360, 93.9%) and the most common type involved harm to skin, tissue or blood vessels (n = 163/360, 45.3%). Forty percent (n = 145) of adverse events occurred within the first week of admission., Conclusion: Adverse events were common in neonatal care, and many occurred during the first days of treatment. Characterisation of adverse events may provide focus areas for improvements in patient safety., (© 2023 The Authors.

Aim: The aims were to characterise paediatric medication errors and to identify the prevalence of known high-alert substances in these errors., Methods: All paediatric drug-related incident reports and complaints nationally reported to the Health and Social Care Inspectorate in Sweden 2011-2017 regarding inpatients were characterised by context and modal details. In addition, drug use at a university hospital was matched to local incident reports. Drug substances were classified using three high-alert lists., Results: On a national level, there were 160 reports (2.5 per 10 000 patients) in which the three high-alert lists were found in different degrees (17/35/47%). Morphine (n = 12), vancomycin (n = 11) and potassium (n = 7) were most frequently involved. Eighty per cent of the reports concerned patients aged 0-6 years. Intravenous was the most common route of administration (66%). On a university hospital level, the prevalence of all types of drug incidents reports was 1.7% among all inpatients. The prevalence of local incident reports involving high-alert substances was almost double that of non-alert substances., Conclusion: Existing high-alert drug lists are relevant for paediatric inpatients. A higher awareness and usage of such lists among hospital staff prescribing, dispensing and administering drugs to children may have the potential to reduce medication errors., (© 2020 The Authors.

Aim: The aim of the present study was to validate the Mosteller formula for the estimation of body surface area (BSA) in various childhood ages. Many physiological processes including drug metabolism correlate with values for BSA. In addition, dosing of many drugs, especially drugs with low therapeutic index, for example, anti-neoplastics, are based on estimated values of BSA., Methods: Published data from measured BSA in 268 children and infants (median age: 8 month; range: 0-18 years) were compared with BSA values estimated by the Mosteller formula. Correlation between estimated and measured BSA values was performed by the Spearman rank correlation. Bias and precision were evaluated as outlined by Sheiner and Beal. Measured and estimated BSA values were compared by the Eksborg's plot., Results: Measured values of BSA and BSA values estimated by the Mosteller formula were closely correlated (r(s) = 0.973; p < 0.0001). The formula of Mosteller had with a precision of 9.38% and underestimated BSA by 4.06%. The quotients Estimated/Measured BSA were within the range 0.9-1.1 in 71.3% of the observations, but deviation up to 35% occurred., Conclusion: The Mosteller formula underestimates BSA in the paediatric population and must be used with precautions because of low precision, most pronounced in neonates and infants., (© 2011 The Author(s)/Acta Paediatrica © 2011 Foundation Acta Paediatrica.)
