Improving intravenous-to-oral antibiotic switch in children: a team-based audit and implementation approach.

Children in hospital are frequently prescribed intravenous antibiotics for longer than needed. Programmes to optimise timely intravenous-to-oral antibiotic switch may limit excessive in-hospital antibiotic use, minimise complications of intravenous therapy and allow children to go home faster. Here, we describe a quality improvement approach to implement a guideline, with team-based education, audit and feedback, for timely, safe switch from intravenous-to-oral antibiotics in hospitalised children. Eligibility for switch was based on evidence-based guidelines and supported by education and feedback. The project was conducted over 12 months in a tertiary paediatric hospital. Primary outcomes assessed were the proportion of eligible children admitted under paediatric and surgical teams switched within 24 hours, and switch timing prior to and after guideline launch. Secondary outcomes were hospital length of stay, recommencement of intravenous therapy or readmission. The percentage of children switched within 24 hours of eligibility significantly increased from 32/50 (64%) at baseline to 203/249 (82%) post-implementation (p=0.006). The median time to switch fell from 15 hours 42 min to 4 hours 20 min (p=0.0006). In addition, there was a 14-hour median reduction in hospital length of stay (p=0.008). Readmission to hospital and recommencement of intravenous therapy did not significantly change postimplementation. This education, audit and feedback approach improved timely intravenous-to-oral switch in children and also allowed for more timely discharge from hospital. The study demonstrates proof of concept for this implementation with a methodology that can be readily adapted to other paediatric inpatient settings.

Spinal cord anomalies in children with anorectal malformations: Ultrasound is a good screening test.

PURPOSE: The purpose of this study is to correlate spinal ultrasound (US) and magnetic resonance imaging (MRI) findings in patients with anorectal malformations (ARMs). METHODS: A retrospective analysis of records was performed for children with ARM presenting to two major pediatric hospitals between 2009 and 2017. The primary outcome analyzed was detection of spinal cord anomalies. Spinal US was performed up to 4 months and MRI within the first year of life. The conus medullaris was considered normal if it had a tapering contour and terminated at or above the Lumbar 2-3 disk space. RESULTS: One hundred ninety-three patients with ARM presented during the study period with a slight male preponderance (108, 56%). Spinal imaging was performed in 157(82%) - 137(87%) had US, 64(41%) had MRI and 44 (28%) had both. Of the 44 who had both; US was abnormal in 25 children-confirmed by MRI in 20 (80%). US was normal in 17 children- MRI showed a filum cyst in 1 and a lipoma in 2 children and was inconclusive in 2 children (p<0.001). All who required surgery except one child, were reported on spinal US to have a low lying cord, borderline low cord or tethered cord (p<.05). No child who was reported to have a normal spinal US required de-tethering at a later stage. Spinal US had an overall sensitivity of 91% and specificity of 75% compared to MRI for detecting spinal cord anomalies in children with ARM CONCLUSIONS: Spinal US performed in a tertiary pediatric imaging department was a good screening test for spinal cord anomalies in children with ARM. The finding of a low, borderline low or tethered cord on US mandates an MRI to confirm the findings and correlates with the need for operative correction of spinal cord tethering. STUDY TYPE: Clinical research paper. LEVEL OF EVIDENCE: 2.

Adherence to surgical antibiotic prophylaxis guidelines in children: A cohort study.

AIMS: Surgical antimicrobial prophylaxis (SAP) is an important measure to reduce post-operative infections. Guidelines exist, but their efficacy and performance in children is poorly understood compared with adults. To review adherence to SAP guidelines, this study assesses risk factors for non-adherence and rate of early post-surgical infections. METHODS: A retrospective cohort study of paediatric surgical cases (0-<18 years) at a tertiary children's hospital was performed. Patient characteristics, surgical factors and antimicrobial details were evaluated against hospital guidelines for overall adherence and domains of: antimicrobial choice, dose, re-dosing, timing and duration. Multiple regression analysis was used to determine risk factors for non-adherence. Hospital records were reviewed for post-operative infections at 7 and 30 days. RESULTS: Among 326 cases, overall guideline adherence was 39.6% but varied by domain and surgical subspecialty. Incorrect wound classification was associated with overall non-adherence on multivariate regression (odds ratio (OR): 2.59; P < 0.001). Incorrect antimicrobial choice was more likely in children with penicillin hypersensitivity (OR 138.34, P = 0.004) and incorrect dosing more likely in adolescent patients (OR 4.33; P = 0.004). Presence of invasive devices was associated with prolonged duration of antimicrobials (OR 2.92, P = 0.016). Only two post-operative infections were documented by 30 days, but data were insufficient to exclude mild infections managed in the community. CONCLUSIONS: SAP was suboptimal in children, with areas for improvement including better guidance on wound classification, allergy management and care for adolescent patients. Documented infections were rare, but mild infections were unable to be excluded due to limited post-discharge information.

Assessment of cooling on an acute scald burn injury in a porcine model.

The current Australian and New Zealand Burn Association (ANZBA) recommended Burns First Aid Treatment is place the burn under cool running water for 20 minutes. Wet towels and water spray also have been used frequently. No scientific data exist to compare the effectiveness of these methods of cooling. This study sought to determine experimental evidence for current Burns First Aid Treatment recommendations and the optimal mode of cooling. Four partial-thickness scald burn injuries were induced in 10 piglets each. First aid was then applied for 20 minutes via cool running water, wet towels, or water spray, with no treatment as a control. At day 1 and day 9, biopsies and clinical photographs were assessed in a blinded manner. The control group showed worsening or no change of depth over the course of 9 days. The outcomes with wet towels and water spray were variable. Cool running water consistently demonstrated improvement in wound recovery over the course of 9 days (P < .05). This study demonstrated that cool running water appeared the most effective first aid for an acute scald burn wound in a porcine model compared with wet towels and water spray.
