Associations between double-checking and medication administration errors: a direct observational study of paediatric inpatients.

BACKGROUND: Double-checking the administration of medications has been standard practice in paediatric hospitals around the world for decades. While the practice is widespread, evidence of its effectiveness in reducing errors or harm is scarce. OBJECTIVES: To measure the association between double-checking, and the occurrence and potential severity of medication administration errors (MAEs); check duration; and factors associated with double-checking adherence. METHODS: Direct observational study of 298 nurses, administering 5140 medication doses to 1523 patients, across nine wards, in a paediatric hospital. Independent observers recorded details of administrations and double-checking (independent; primed-one nurse shares information which may influence the checking nurse; incomplete; or none) in real time during weekdays and weekends between 07:00 and 22:00. Observational medication data were compared with patients' medical records by a reviewer (blinded to checking-status), to identify MAEs. MAEs were rated for potential severity. Observations included administrations where double-checking was mandated, or optional. Multivariable regression examined the association between double-checking, MAEs and potential severity; and factors associated with policy adherence. RESULTS: For 3563 administrations double-checking was mandated. Of these, 36 (1·0%) received independent double-checks, 3296 (92·5%) primed and 231 (6·5%) no/incomplete double-checks. For 1577 administrations double-checking was not mandatory, but in 26·3% (n=416) nurses chose to double-check. Where double-checking was mandated there was no significant association between double-checking and MAEs (OR 0·89 (0·65-1·21); p=0·44), or potential MAE severity (OR 0·86 (0·65-1·15); p=0·31). Where double-checking was not mandated, but performed, MAEs were less likely to occur (OR 0·71 (0·54-0·95); p=0·02) and had lower potential severity (OR 0·75 (0·57-0·99); p=0·04). Each double-check took an average of 6·4 min (107 hours/1000 administrations). CONCLUSIONS: Compliance with mandated double-checking was very high, but rarely independent. Primed double-checking was highly prevalent but compared with single-checking conferred no benefit in terms of reduced errors or severity. Our findings raise questions about if, when and how double-checking policies deliver safety benefits and warrant the considerable resource investments required in modern clinical settings.

Cause, treatment costs and 12-month functional outcomes of children with major injury in NSW, Australia.

BACKGROUND: Information about children treated in New South Wales (NSW), Australia following major injury has been limited to those treated at trauma centres using mortality as the main outcome measure, restricting assessment of the effectiveness of the Trauma System. This study sought to describe the detailed characteristics as well as functional and psychosocial health outcomes of all children suffering major injury in NSW. METHODS: A longitudinal study was conducted between July 2015 and November 2017 and included children < 16 years requiring intensive care or an injury severity score (ISS) ≥ 9 treated in NSW or who died following injury. Children were identified through the three NSW Paediatric Trauma Centres (PTC), the NSW Trauma Registry, NSW Aeromedical Retrieval Registry (AirMaestro) and the National Coronial Information System (NCIS). Health-related quality of life (HRQoL) outcomes for children treated at the three PTCs were collected at baseline, 6 and 12 months using the Paediatric Quality of Life inventory (PedsQL 4.0) and EuroQol five-dimensional EQ-5D-Y. RESULTS: There were 625 children, with a median (interquartile range) age of 7 (2-13) years and 71.7% were male. Around half were injured in major cities (51.2%). The median (IQR) injury severity score (ISS) was 10 (9-17). Twelve-month HRQoL measured by PedsQL remained below baseline for psychosocial health. Treatment costs increased with injury severity (p=<0.001) and polytrauma (p=<0.001). No survival benefit was demonstrated between PTC versus non-PTC definitive care. Injured females and children from rural / remote NSW were overrepresented in the deceased. CONCLUSION: Children treated in NSW following major injury have reduced quality of life and in particular, reduced emotional well-being at 12 months post-injury. Improved psychosocial care and outpatient follow-up is required to minimise the long-term emotional impact of injury on the child.

Management of fever in Australian children: a population-based sample survey.

BACKGROUND: Fever in childhood is a common acute presentation requiring clinical triage to identify the few children who have serious underlying infection. Clinical practice guidelines (CPGs) have been developed to assist clinicians with this task. This study aimed to assess the proportion of care provided in accordance with CPG recommendations for the management of fever in Australian children. METHODS: Clinical recommendations were extracted from five CPGs and formulated into 47 clinical indicators for use in auditing adherence. Indicators were categorised by phase of care: assessment, diagnosis and treatment. Patient records from children aged 0 to 15 years were sampled from general practices (GP), emergency departments (ED) and hospital admissions in randomly-selected health districts in Queensland, New South Wales and South Australia during 2012 and 2013. Paediatric nurses, trained to assess eligibility for indicator assessment and adherence, reviewed eligible medical records. Adherence was estimated by individual indicator, phase of care, age-group and setting. RESULTS: The field team conducted 14,879 eligible indicator assessments for 708 visits by 550 children with fever in 58 GP, 34 ED and 28 hospital inpatient settings. For the 33 indicators with sufficient data, adherence ranged from 14.7 to 98.1%. Estimated adherence with assessment-related indicators was 51.3% (95% CI: 48.1-54.6), 77.5% (95% CI: 65.3-87.1) for diagnostic-related indicators and 72.7% (95% CI: 65.3-79.3) for treatment-related indicators. Adherence for children < 3 months of age was 73.4% (95% CI: 58.0-85.8) and 64.7% (95% CI: 57.0-71.9) for children 3-11 months of age, both significantly higher than for children aged 4-15 years (53.5%; 95% CI: 50.0-56.9). The proportion of adherent care for children attending an ED was 77.5% (95% CI: 74.2-80.6) and 76.7% (95% CI: 71.7-81.3) for children admitted to hospital, both significantly higher than for children attending a GP (40.3%; 95% CI: 34.6-46.1). CONCLUSIONS: This study reports a wide range of adherence by clinicians to 47 indicators of best practice for the management of febrile children, sampled from urban and rural regions containing 60% of the Australian paediatric population. Documented adherence was lowest for indicators related to patient assessment, for care provided in GP settings, and for children aged 4-15 years.

A population-based comparison of the post-operative outcomes of open and laparoscopic appendicectomy in children.

OBJECTIVE: To assess and compare the post-operative outcomes of open and laparoscopic appendicectomy in children. DESIGN: Record linkage analysis of administrative hospital (Admitted Patient Data Collection) and emergency department (Emergency Department Data Collection) data.Participants, setting: Children under 16 years of age who underwent an appendicectomy in a public or private hospital in New South Wales between January 2002 and December 2013. MAIN OUTCOME MEASURES: Association between type of appendicectomy and post-operative complications within 28 days of discharge, adjusted for patient characteristics and type of hospital. RESULTS: Of 23 961 children who underwent appendicectomy, 19 336 (81%) had uncomplicated appendicitis and 4625 (19%) had appendicitis complicated by abscess, perforation, or peritonitis. The proportion of laparoscopic appendicectomies increased from 11.8% in 2002 to 85.8% in 2013. In cases of uncomplicated appendicitis, laparoscopic appendicectomy was associated with more post-operative complications (mostly symptomatic re-admissions or emergency department presentations) than open appendicectomy (7.4% v 5.8%), but with a reduced risk of post-operative intestinal obstruction (adjusted odds ratio [aOR], 0.59; 95% CI, 0.36-0.97). For cases of complicated appendicitis, the risk of wound infections was lower for laparoscopic appendicectomy (aOR, 0.67; 95% CI, 0.50-0.90), but not the risks of intestinal obstruction (aOR, 0.97; 95% CI, 0.62-1.52) or intra-abdominal abscess (aOR, 1.06; 95% CI, 0.72-1.55). CONCLUSION: Post-appendicectomy outcomes were similar for most age groups and hospital types. Children with uncomplicated appendicitis have lower risk of post-operative bowel obstruction after laparoscopic appendicectomy than after open appendicectomy, but may be discharged before their post-operative symptoms have adequately resolved.

A Child With a Burn-Related Foot and Ankle Contracture Treated With Multiple Modalities.

PURPOSE: The presence of hypertrophic scars, which cross lower extremity joints, can often result in decreased range of motion, limitations in functional mobility, and gait deviations. This article reviews a case and describes a multimodal treatment approach. SUMMARY OF KEY POINTS: A 6-year-old girl developed aggressive hypertrophic scars following a burn injury. A multimodal treatment approach, including splinting, elastomers, and physical therapy, was developed. CONCLUSIONS: Rapid improvements were demonstrated in measured objective outcomes. RECOMMENDATIONS FOR CLINICAL PRACTICE: Early multimodal intervention, in addition to range of motion, stretching, massage, and compression garments, is recommended when treating hypertrophic scars. This case suggests that further study into a multimodal treatment approach may be beneficial to develop a standardized protocol for more efficient scar management.

Detection and identification of bacteria using antibiotic susceptibility and a multi-array electrochemical sensor with pattern recognition.

This work proposes the use of amperometric signals generated by a 96-well multi-array dissolved oxygen multi-electrode sensor (DOX) coupled with principal component analysis for continuous monitoring, identification and differentiation of bacteria. Two types of differentiation mechanisms were tested: (1) direct monitoring of respiratory activity via oxygen consumption and (2) quantification of the effect of three broad-spectrum antibiotics on bacteria growth and respiration over time. Five species of bacteria were examined including: Escherichia coli, Escherichia adecarboxylata, Comamonas acidovorans, Corynebacterium glutamicum and Staphylococcus epidermidis. The addition of small concentrations of antibiotics to the growth medium alters the oxygen consumption of the cells and a unique fingerprint is created for a specific cell. This fingerprint is shown to evolve over a specific concentration range that is dependant of instrumental constraints of the DOX system. The application of principal component analysis (PCA) to classify the data was also examined. It was shown that bacteria could be classified simply by their oxygen consumption rates over a varying concentration range. Discrimination between species can also be increased by the effects of the antibiotics on the oxygen consumption of varying concentrations of cells. The proposed DOX-PCA system illustrates a generic template that can be tailored to meet specific research goals by the selection of specific cell/antibiotic combinations and concentrations.

Assay of teicoplanin in serum: comparison of high-performance liquid chromatography and fluorescence polarization immunoassay.

A simple liquid extraction coupled with reverse-phase HPLC and UV detection was shown to correlate well with fluorescence polarization immunoassay (FPIA) on the Abbott TD(x) analyser for serum teicoplanin analysis, r(2) = 0.974, HPLC = 0.908 TDx + 2.324. A Bland-Altman plot showed no significant bias between the results. The HPLC method was linear over the range 10-100 mg/L. The HPLC method showed very good reproducibility, comparable to FPIA. The inter-assay coefficients of variation were 2.76%, 2.29% and 2.65% at 10.3, 51.4 and 77.1 mg/L, respectively, with intra-assay coefficients of variation of 1.86%, 1.97% and 1.17% at 9.13, 50.65 and 75.1 mg/L, respectively. Recoveries were between 99.1 and 101.8% within the analytical range. The HPLC method described is simple, robust, highly reproducible and suited to a clinical laboratory with the appropriate equipment.
