Objective: Hospital utilisation research is important in pursuing cost-saving healthcare models. Tonsillectomy is one of the most common paediatric surgeries and the most frequent reason for paediatric hospital readmission. This study aimed to report the government-funded costs of paediatric tonsillectomy in the state of Victoria, Australia, extrapolate costs across Australia, and identify the cost determinants. Methods: A population-based longitudinal study was conducted with a bottom-up costing approach using linked datasets containing all paediatric tonsillectomy and tonsillectomy with adenoidectomy surgeries performed in the state of Victoria between 2010 and 2015. Results: The total average annual cost of tonsillectomy hospitalisation in Victoria was A$21 937 155 with a median admission cost of A$2224 (interquartile range (IQR) 1826–2560). Inflation-adjusted annual tonsillectomy costs increased during 2010–2015 (P < 0.001), not explained by the rising number of surgeries. Hospital readmissions resulted in a total average annual cost of A$1 427 716, with each readmission costing approximately A$2411 (IQR 1936–2732). The most common reason for readmission was haemorrhage, which was associated with the highest total cost. The estimated total annual expenditure of both tonsillectomy and resulting readmissions across Australia was A$126 705 989. Surgical cost in the upper quartile was associated with younger age, male sex, lower socioeconomic status, surgery for reasons other than infection alone, overnight vs day case surgery, public hospitals and metropolitan hospitals. Surgery for obstructed breathing during sleep had the strongest association to high surgical cost. Conclusions: This study highlights the cost of paediatric tonsillectomy and associated hospital readmissions. The study findings will inform healthcare reform and serve as a basis for strategies to optimise patient outcomes while reducing both postoperative complications and costs. What this known about the topic? Tonsillectomy is one of the most common surgeries in childhood and the most frequent reason for paediatric unplanned hospital readmissions. There is growing interest in cost containment and a value-based model of funding. What does this paper add? This is the first study to investigate the economic effect of paediatric tonsillectomy at a national level worldwide. The estimated national annual cost of tonsillectomy was A$126 705 989 and rising. What are the implications for practitioners? These findings will inform healthcare reform that aims to contain costs while optimising patient outcomes. [ABSTRACT FROM AUTHOR]

Background: Tonsillectomy, with or without adenoidectomy, is the leading reason for paediatric unplanned hospital readmission, some of which are potentially avoidable. Reducing unplanned hospital revisits would improve patient safety and decrease use of healthcare resources. This study aimed to describe the incidence, timing and risk factors for any surgery-related hospital revisits (both emergency presentation and readmission) following paediatric tonsillectomy and adenotonsillectomy in a large state-wide cohort. Methods: We conducted a population-based cohort study using linked administrative datasets capturing all paediatric tonsillectomy and adenotonsillectomy surgeries performed between 2010 and 2015 in the state of Victoria, Australia. The primary outcome was presentation to the emergency department or hospital readmission within 30-day post-surgery. Results: Between 2010 and 2015, 46,583 patients underwent 47,054 surgeries. There was a total of 4758 emergency department presentations (10.11% total surgeries) and 2750 readmissions (5.84% total surgeries). Haemorrhage was the most common reason for both revisit types, associated with 33.02% of ED presentations (3.34% total surgeries) and 67.93% of readmissions (3.97% total surgeries). Day 5 post-surgery was the median revisit time for both ED presentations (IQR 3–7) and readmission (IQR 3–8). Predictors of revisit included older age, public and metropolitan hospitals and peri-operative complications during surgery. Conclusions: Haemorrhage was the most common reason for both emergency department presentation and hospital readmission. The higher risk of revisits associated with older children, surgeries performed in public and metropolitan hospitals, and in patients experiencing peri-operative complications, suggest the need for improved education of postoperative care for caregivers, and avoidance of inappropriate early discharge.

Objective: To describe the contemporary epidemiology of paediatric adenotonsillectomy in an Australian setting, examine the incidence rate over 2010‐2015 and investigate factors associated with inter‐hospital transfer. Design: Retrospective population‐based study. Setting: Multicentre study in the state of Victoria, Australia. Participants: From the Victorian Admitted Episodes Dataset, which included all patients aged 0‐19 years who underwent adenoidectomy and/or tonsillectomy in Victoria, Australia between 2010 and 2015. Main Outcome Measures: Annual incidence rate, hospital volume, inter‐hospital transfer. Results: Between 2010 and 2015, 59 008 patients underwent 61 281 procedures, with highest number performed in males (52.7%), children aged under 10 years (73.5%) and in the higher socioeconomic groups (24.6% in quintile 4 and 23.2% in quintile 5). Seventy‐five cases (0.12%) resulted in inter‐hospital transfer, which was significantly associated with young age (under 5 years). More than a third of hospitals (35.7%) performed an average rate of <1 procedure per week. Hospital volume was not associated with risk of inter‐hospital transfer. The incidence rate of adenotonsillectomy procedures significantly increased over the study period (P < .001), driven by a significant increase in the rate of surgery performed for obstructive symptoms (P < .001). Conclusions: The rate of adenoidectomy/tonsillectomy procedures is rising, with a higher proportion being performed in socioeconomically advantaged patients. This raises concerns regarding healthcare access, given the literature supporting higher rates of obstructive sleep‐disordered breathing and sore throat in lower socioeconomic groups. A third of hospitals performed small numbers of procedures, but we found no association between hospital volume and inter‐hospital transfers. [ABSTRACT FROM AUTHOR]

Objectives: To describe the incidence of and patterns of 'escalated care' (care in addition to standard treatment with systemic corticosteroids and inhaled bronchodilators) for children receiving prehospital treatment for asthma., Design: Retrospective observational study., Setting: State-wide ambulance service data (Ambulance Victoria in Victoria, Australia, population 6.5 million) PARTICIPANTS: Children aged 1-17 years and given a final diagnosis of asthma by the treating paramedics and/or treated with inhaled bronchodilators from 1 July 2019 to 30 June 2020., Primary and Secondary Outcome Measures: We classified 'escalation of care' as parenteral administration of epinephrine, or provision of respiratory support. We compared clinical, demographic and treatments administered between those receiving and not receiving escalation of care., Results: Paramedics attended 1572 children with acute exacerbations of asthma during the 1 year study period. Of these, 22 (1.4%) had escalated care, all receiving parenteral epinephrine. Patients with escalated care were more likely to be older, had previously required hospital admission for asthma and had severe respiratory distress at initial assessment.Of 1307 children with respiratory status data available, at arrival to hospital, the respiratory status of children had improved overall (normal/mild respiratory distress at initial assessment 847 (64.8%), normal/mild respiratory distress at hospital arrival 1142 (87.4%), p<0.0001)., Conclusions: Most children with acute exacerbations of asthma did not receive escalated therapy during their pre-hospital treatment from ambulance paramedics. Most patients were treated with inhaled bronchodilators only and clinically improved by the time they arrived in hospital., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Geographic variation of paediatric tonsillectomy, with or without adenoidectomy, (A/T) has been described since the 1930s until today but no studies have investigated the factors associated with this variation. This study described the geographical distribution of paediatric A/T across the state of Victoria, Australia, and investigated area-level factors associated with this variation. We used linked administrative datasets capturing all paediatric A/T performed between 2010 and 2015 in Victoria. Surgery data were collapsed by patient residence to the level of Local Government Area. Regression models were used to investigate the association between likelihood of surgery and area-level factors. We found a 10.2-fold difference in A/T rates across the state, with areas of higher rates more in regional than metropolitan areas. Area-level factors associated with geographic variation of A/T were percentage of children aged 5-9 years (IRR 1.07, 95%CI 1.01-1.14, P = 0.03) and low English language proficiency (IRR 0.95, 95% CI 0.90-0.99, P = 0.03). In a sub-population analysis of surgeries in the public sector, these factors were low maternal educational attainment (IRR 1.09, 95% CI 1.02-1.16, P < 0.001) and surgical waiting time (IRR 0.99635 95% CI 0.99273-0.99997, P = 0.048). Identifying areas of focus for improvement and factors associated with geographic variation will assist in improving equitable provision of paediatric A/T and decrease variability within regions., (© 2021.

Aim: Pulse oximetry has become a widely used technology in medicine and is a standard part of monitoring in neonatal medicine. Knowledge of basic principles, clinical and technical considerations is important to optimise clinical benefit of use, but have been shown to be insufficient in paediatric staff. We aimed to assess knowledge of pulse oximetry in neonatal medical staff, a population not previously studied., Methods: A 21-item questionnaire (seven demographic, 14 knowledge) was devised and then administered to neonatal medical staff at all postgraduate levels working in the major public neonatal services in the state of Victoria, Australia., Results: Average test score was 64.4% (range 30.8-92.3%) with no correlation between years of experience and score. All respondents reported experience with oximetry, but only 57% reported adequate training in practical oximetry skills and only 28% in interpretation of downloaded oximetry data. About 45% reported knowing what an averaging time was but only 29% were able to provide an acceptable definition and only 10% knew what averaging time was used on devices in their units., Conclusion: Significant knowledge deficits regarding oximetry are evident in neonatal staff, supporting the need for targeted and continuous training in oximetry., (©2018 Foundation Acta Paediatrica.

Objective: Sleep-disordered breathing (SDB) is associated with reduced nocturnal dipping of blood pressure (BP) and sleep disruption in adults, and these features confer an increased risk of cardiovascular events. As SDB prevalence in children peaks during the preschool years, we investigated nocturnal dipping and sleep fragmentation in preschool children with SDB., Methods: Children (3-5 years; n=163) grouped by obstructive apnoea hypopnoea index (OAHI): control, no snoring history and OAHI ≤1 event/h; primary snoring, OAHI ≤1 event/h; mild SDB, >1-≤5 events/h; moderate-severe SDB, >5 events/h. Pulse transit time (PTT), an inverse continuous indicator of BP changes, and heart rate (HR) during total sleep time and the first period of rapid eye movement (REM), non-REM (NREM)1/2 and NREM3/4 sleep were expressed as percentage change from wake before sleep onset. The sleep fragmentation index (SFI) was calculated as the number of sleep stage transitions or awakenings per hour of sleep., Results: There were no group differences in the change in PTT or HR from wake to total sleep time or to individual sleep stages or in the proportion of children in the quartile with the smallest change in PTT during total sleep. Children with moderate-severe SDB had higher SFI than primary snoring (PS) or mild SDB groups (p<0.05 for both) and controls (p=0.07)., Conclusions: In contrast to adults, nocturnal dipping is preserved in young children with SDB, despite increased sleep fragmentation. As there is evidence that nocturnal dipping is similarly preserved at the school age, childhood may pose a window of opportunity for resolution of SDB when the cardiovascular effects are less marked., (Copyright © 2014 Elsevier B.V.

Sleep disorders are very common in childhood and are often amenable to simple advice and parental education. Questions about sleep should be an integral part of every paediatric consultation. Children with underlying syndromes or complex medical conditions often have multiple sleep issues. Excessive sleepiness in children requires careful history-taking and consideration of specialised investigation. Obstructive sleep apnoea (OSA) is a common condition in childhood with important health implications. The high prevalence of OSA warrants rigorous attempts to identify children at higher risk and manage them appropriately. Adenotonsillectomy is a highly efficacious therapy for paediatric OSA. A current major issue is to improve ways of distinguishing mild from severe OSA before a child undergoes adenotonsillectomy, as those with more severe disease are at increased risk of postoperative complications and should undergo adenotonsillectomy in a tertiary centre. Children with obesity and other comorbid conditions are at increased risk of persisting OSA despite adenotonsillectomy. Topical (nasal) steroids and/or anti-inflammatory agents have a role in the non-surgical treatment of mild OSA. Continuous positive airway pressure and orthodontic interventions are treatment options for treatment of persisting OSA in children.

Cross-infection by Pseudomonas aeruginosa between unrelated patients with cystic fibrosis (CF) is believed to be uncommon. After detecting a genotypically identical strain of P. aeruginosa in five unrelated children with CF dying from severe lung disease, we determined its prevalence within a large CF clinic using pulsed-field gel electrophoresis and random amplified polymorphic DNA assays. The clinical status of P. aeruginosa-infected patients was also determined. Between September and December 1999, 152 patients, aged 3.9-20.7 years, provided sputum for culture. P. aeruginosa was detected in 118 children of mean (SD) age 13.5 (3.8) years. The genotyping techniques were concordant, showing that 65 (55%) infected patients carried an indistinguishable or closely related strain. No distinctive antibiogram or environmental reservoir was found. Patients with the clonal strain were more likely than those with unrelated isolates to have been hospitalized in the preceding 12 months for respiratory exacerbations. This study demonstrates extensive spread of a single, clonal strain of P. aeruginosa in a large pediatric CF clinic. Whether this strain is also more virulent than sporadic isolates remains to be determined. As transmissible strains could emerge elsewhere, other CF clinics may also need to consider molecular methods of surveillance for cross-infection.
