Difficulties with assessment and management of an infant\u27s distress in the postoperative period: optimising opportunities for interdisciplinary information-sharing
OBJECTIVES: The importance of accurate paediatric patient assessment is well established but under-utilised in managing postoperative medication regimens.METHODS: Data for this case report were collected through observations of clinical practice, conduct of interviews, and retrieval of information from the medical record. This case report involving a hospitalised 1-year-old boy demonstrates the difficulties associated with assessing and managing postoperative distress, including pain and other clinical conditions related to the surgical procedure.RESULTS: Postoperatively, there were difficulties in managing pain and an episode of over-sedation, occasioning opiate reversal with naloxone. In addition, he had decreasing oxygen saturation and increased work of breathing. X-ray showed changes consistent with either atelectasis or aspiration, and he was commenced on antibiotics. The patient experienced respiratory distress and required intervention from the medical emergency team.CONCLUSION: This case demonstrated the importance of comprehensive assessment and careful consideration of alternative causes of an infant\u27s distress using the results of assessment tools to aid decision-making. Communication moderates effective patient care, and more favourable outcomes could be achieved by optimising interdisciplinary information-sharing
A randomized controlled trial investigation of a non-stimulant in attention deficit hyperactivity disorder (ACTION): Rationale and design
<p>Abstract</p> <p>Background</p> <p>The ACTION study (<it>Attention deficit hyperactivity disorder Controlled Trial Investigation Of a Non-stimulant) </it>is a multi-center, double-blind, randomized cross-over trial of the non-stimulant medication, Atomoxetine, in children and adolescents with attention deficit hyperactivity disorder (ADHD). The primary aims are to examine the efficacy of atomoxetine for improving cognition and emotional function in ADHD and whether any improvements in these outcomes are more pronounced in participants with comorbid anxiety; and to determine if changes in these outcomes after atomoxetine are more reliable than changes in diagnostic symptoms of ADHD. This manuscript will describe the methodology and rationale for the ACTION study.</p> <p>Methods</p> <p>Children and adolescents aged 6 - 17 y with ADHD will be enrolled. Clinical interview and validated scales will be used to confirm diagnosis and screen for exclusion criteria, which include concurrent stimulant use, and comorbid psychiatric or neurological conditions other than anxiety. Three assessment sessions will be conducted over the 13-week study period: Session 1 (Baseline, pre-treatment), Session 2 (six weeks, atomoxetine or placebo), and Session 3 (13 weeks, cross-over after one-week washout period). The standardized touch-screen battery, "IntegNeuroâ˘", will be used to assess cognitive and emotional function. The primary measure of response will be symptom ratings, while quality of life will be a secondary outcome. Logistic regression will be used to determine predictors of treatment response, while repeated measures of analysis will determine any differences in effect of atomoxetine and placebo.</p> <p>Results</p> <p>The methodology for the ACTION study has been detailed.</p> <p>Conclusions</p> <p>The ACTION study is the first controlled trial to investigate the efficacy of atomoxetine using objective cognitive and emotional function markers, and whether these objective measures predict outcomes with atomoxetine in ADHD with and without comorbid anxiety. First enrollment was in March 2008. The outcomes of this study will be a significant step towards a 'personalized medicine' (and therefore a more efficient) approach to ADHD treatment.</p> <p>Trial registration</p> <p>Australian and New Zealand Clinical Trials Registry <a href="http://www.anzctr.org.au/ANZCTRN12607000535471.aspx">ANZCTRN12607000535471</a>.</p
Impact of antibiotic allergy labels on patient outcomes in a tertiary paediatric hospital
Aims
Antibiotic allergies are reported in 5â15% of children. This study aimed to evaluate the impact of common βâlactam antibiotic allergy labels (AALs) on hospital treatment, focusing on length of stay and appropriateness of antibiotic prescribing. Methods
This was a retrospective cohort study over 21âmonths at the Royal Children's Hospital Melbourne, Australia. A subset of children with the most common βâlactam allergies, and who required admission for intravenous antibiotics over a 12âmonth period, was analysed for appropriateness of prescribing. Nonâallergic patients were matched to evaluate associations between AALs and hospital treatment. Results
There were 98â912 children admitted over the study period, of whom 938 (1%) had at least one AAL on first admission. Of all encounters, 5145 (2.5%) were for children with AALs. The most common AALs were to amoxicillin and amoxicillinâclavulanic acid combinations (40.8%), cefalexin (14.4%) and trimethoprimâsulfamethoxazole (9.7%). For the subset, there were 66 admissions for children who required intravenous antibiotics. Documentation was adequate for 27% of AALs. Inappropriate prescribing occurred in almost half (47%). Hospital stay was longer for children with AALs (median 4.7 days; IQR 2.3â9.2) compared to nonâallergic controls (median 3.9 days; IQR 1.9â6.8; P â=â.02). Children with AALs were more likely to receive restricted antibiotics (aOR 3.03; 95% CI, 1.45â6.30; P â=â.003). Conclusion
This is the first study to demonstrate high rates of inappropriate prescribing in children with AALs. Children with AALs were significantly more likely to receive restricted antibiotics and had a longer length of stay compared with nonâallergic controls.</p
Optimizing mycophenolic acid exposure in kidney transplant recipients: time for target concentration intervention
The immunosuppressive agent mycophenolate is used extensively in kidney transplantation, yet dosing strategy applied varies markedly from fixed dosing ("one-dose-fits-all"), to mycophenolic acid (MPA) trough concentration monitoring, to dose optimization to an MPA exposure target (as area under the concentration-time curve [MPA AUC0-12]). This relates in part to inconsistent results in prospective trials of concentration-controlled dosing (CCD). In this review, the totality of evidence supporting mycophenolate CCD is examined: pharmacological characteristics, observational data linking exposure to efficacy and toxicities, and randomized controlled trials of CCD, with attention to dose optimization method and exposure achieved. Fixed dosing of mycophenolate consistently leads to underexposure associated with rejection, as well as overexposure associated with toxicities. When CCD is driven by pharmacokinetic calculation to a target concentration (target concentration intervention), MPA exposure is successfully controlled and clinical benefits are seen. There remains a need for consensus on practical aspects of mycophenolate target concentration intervention in contemporary tacrolimus-containing regimens and future research to define maintenance phase exposure targets. However, given ongoing consequences of both overimmunosuppression and underimmunosuppression in kidney transplantation, impacting short- and long-term outcomes, these should be a priority. The imprecise "one-dose-fits-all" approach should be replaced by the clinically proven MPA target concentration strategy
