Studies show that conservative management in acute uncomplicated appendicitis (AUA) is an alternative to surgery. This study aims to determine factors affecting parental preference in management of AUA and their decision for research participation. We conducted surveys on parents whose children were admitted with suspicion of appendicitis but later confirmed not to have appendicitis. Information on appendicectomy versus conservative treatment with antibiotics was provided using a fixed script and standard information leaflet. Questionnaires covered factors influencing decisions, opinions regarding research, treatment preference and demographic data. We excluded parents not fluent in English. Of 113 respondents, 71(62.8%) chose antibiotics, 39(34.5%) chose appendicectomy, and 3(2.7%) had no preference. Reasons given for choosing antibiotics were fear of surgical risks and preferring less invasive treatment. Those choosing appendicectomy expressed preference for definitive treatment and fear of recurrence. Majority were against randomisation (n = 89, 78.8%) and blinding (n = 90, 79.7%). Over half found difficulty involving their child in research (n = 65, 57.5%). Most thought that research is important (66.4%) and beneficial to others (59.3%). Parents who perceived their child as healthy found research riskier (p = 0.039). Educated parents were more likely to find research beneficial to others (p = 0.012) but less accepting of randomisation (p = 0.001).Conclusion: More parents appear to prefer conservative treatment for acute uncomplicated appendicitis. Researchers must consider parental concerns regarding randomisation and blinding.What is Known:• Conservative management of acute uncomplicated appendicitis in paediatric patients is safe and effective, sparing the child the need for an operation; however, neither conservative nor surgical management is proven to be superior.• Randomised controlled trials provide the highest level of evidence, but it is challenging to recruit paediatric patients as participants in such clinical trials.What is New:• More parents prefer conservative management of uncomplicated appendicitis over surgical management for their children due to fear of surgical risks and complications• Randomisation in trial design is significantly associated with a parent's decision to reject their child's participation in a clinical trial.
A pilot study comparing parent and adolescent online health information seeking behaviours in elective pediatric surgical situations

Wong SSM, Wong KPL, Angus MIL, Chen Y, Choo CSC, Nah SA

Pediatr Surg Int, 2020 Feb;36(2):227-233.
PMID: 31654110 DOI: 10.1007/s00383-019-04592-0

PURPOSE: Little is known of how children seek health information. This study evaluates online health information (OHI) seeking behaviours in adolescents undergoing major elective surgical procedures and compares responses within parent-child dyads.
METHODS: With institutional approval, we prospectively surveyed parents of children admitted to our institution for major elective operations between November 2017 and November 2018, using convenience sampling. Patients aged 12 years and above were also invited. Each respondent completed an anonymized modification of a previously published survey on Internet usage. Chi squared tests were used for categorical data, with significance at P value
Fulltext Management of acute testicular pain in children: changing trends with improvements in scrotal ultrasonography over 18 years

INTRODUCTION: Doppler scrotal ultrasonography (US) is the modality of choice in diagnosing testicular torsion. We aimed to evaluate the performance of scrotal US in diagnosing testicular torsion over the past 18 years in our institution and determine the factors contributing to the length of wait times for it.
METHODS: A retrospective review was conducted of boys who presented with acute scrotal pain from 2014 to 2015. US reports, operative findings, final diagnosis and key time points of the patients' journey (time to emergency department consultation, time to admission, time to US and time to operating theatre [OT]) were collected. US performance results were compared with those observed in a historical cohort from 1998 to 2004. Wait times were compared between operated and non-operated patients.
RESULTS: Data from 519 boys with a mean age of 9.15 years was collected. Of these, 438 (84.4%) boys had undergone initial scrotal US; of these scrotal US cases, 28 were surgically explored, with 23 confirmed to have torsion. Another five cases were explored without prior US, and all were confirmed to have torsion. Performance analysis of US showed a sensitivity of 100% and a specificity of 98.8%. There was no significant difference between wait times of operated and non-operated patients. Time to US (P < 0.0001, r = 0.96) and time to OT (P < 0.0001, r = 0.64) correlated significantly with the total time from presentation to surgery.
CONCLUSION: There has been an improvement in the diagnostic performance of scrotal US for testicular torsion over the past 18 years. Quality improvement programmes targeted at reducing wait times for patients presenting with acute scrotum should target time to US and time to OT.
Home-Initiated-Programme-to-Prepare-for-Operation: evaluating the effect of an animation video on peri-operative anxiety in children: A randomised controlled trial

Nair T, Choo CSC, Abdullah NS, Lee S, Teo LLE, Chen Y, et al.

Eur J Anaesthesiol, 2021 Aug 01;38(8):880-887.
PMID: 33186309 DOI: 10.1097/EJA.0000000000001385

BACKGROUND: Hospital admissions and surgical operations commonly trigger anxiety in young children. Despite employing numerous support measures in our hospital, such as a pre-operative play room, the encouragement of parental companionship during induction of anaesthesia and distraction therapy, allaying the anxiety of our young surgical patients remains a challenge.
OBJECTIVES: To evaluate the effectiveness of a Home-Initiated-Programme-to-Prepare-for-Operation (HIPPO) on emotional manifestation and anxiety in children undergoing surgery.
DESIGN, SETTING AND PATIENTS: One hundred and thirty children were randomly assigned to either control or intervention group between February 2018 and April 2019 in a tertiary paediatric hospital in Singapore.
INTERVENTION: In addition to our standard pre-operative workflow, the intervention group received an additional home preparation kit consisting of an animated video on preoperative preparation and age-specific preoperative preparation activity sheets.
MAIN OUTCOME MEASURES: The primary outcome was the Children's Emotional Manifestation Scale score to evaluate behaviour and emotion in the children before and during induction of anaesthesia. Secondary outcomes evaluated anxiety levels in parents and children, the child's behaviour and degree of co-operation using the State-Trait Anxiety Inventory scores, State-Trait Anxiety Inventory Children scores, the Induction Compliance Checklist scores, the Visual Analogue Scale scores for anxiety and the feedback questionnaire.
RESULTS: The difference between the Children's Emotional Manifestation Scale score in control and intervention groups was not statistically significant. A promising difference was however observed in one of the secondary outcomes where the state-State-Trait Anxiety Inventory Children scores of 7 to 10-year olds in the intervention group almost reached significance; P = 0.067.
CONCLUSION: Despite being a child-friendly, easily accessible and affordable tool for patient education, HIPPO did not reduce anxiety experienced by children in the pre-operative waiting area or during induction of anaesthesia.
