Protocol for the implementation evaluation of an integrated paediatric and primary care model: Strengthening Care for Children (SC4C).

INTRODUCTION: Implementation evaluations provide insight into how interventions are delivered across varying contexts and why interventions work in some contexts and not in others. This manuscript outlines a detailed protocol of an implementation evaluation embedded in a stepped-wedge cluster randomised controlled trial of a model of care, Strengthening Care for Children (SC4C), that integrates paediatric care in general practice. The purpose of this manuscript is to describe the pragmatic methods that will be used to capture implementation evaluation process and outcome data within this trial. METHODS AND ANALYSIS: Our implementation evaluation will use a mixed methods design, with data collected in the intervention arm of the SC4C trial guided by a logic model developed using the Consolidated Framework for Implementation Research (CFIR) and Proctor and colleague's taxonomy of implementation outcomes. Data collection will be via questionnaires and semistructured interviews with general practitioners, paediatricians, general practice administrative staff and children and families. Each of the 21 general practices recruited into the study will be described in terms of staffing, patient throughput and location, in addition to the nuanced inner and outer contexts, use of the intervention and its acceptability. We will quantify implementation effectiveness in each general practice clinic using the CFIR validated scoring system. Importantly, we have embedded data collection post intervention to enable assessment of the sustainable adoption of the intervention. An inductive approach to the analysis of qualitative data will identify additional emerging themes that may not be covered by the formal frameworks underpinning our analysis. ETHICS AND DISSEMINATION: Ethical approval was granted by the Royal Children's Hospital Ethics Committee in August 2020 (HREC: 65955). Results will be submitted for publication in peer-reviewed journals and presented at relevant conferences.

Feasibility of single question mental health surveillance in chronic disease.

OBJECTIVE: To determine the (1) feasibility and acceptability of administering single question mental health surveillance to carers of children with chronic disease in the inpatient setting and (2) sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of this question to detect 'at risk' children compared with the Strengths and Difficulties Questionnaire (SDQ). DESIGN: Cross-sectional pilot SETTING: Day Medical Unit of a tertiary paediatric hospital, 1 April 2021-31 July 2021. PATIENTS: Carers of children aged 2-17 years with chronic medical conditions. INTERVENTIONS: Caregivers were asked to respond to 'Thinking about your child's mental health over the past 4 weeks, are they thriving/coping/struggling/always overwhelmed?' during the admission process. All carers and children 11-17 years were invited to complete the SDQ. MAIN OUTCOME MEASURES: Feasibility and acceptability were determined by nursing feedback. Sensitivity, specificity, PPV and NPV were determined by comparing question responses with clinical cut-points on the SDQ. RESULTS: 213 carers responded to the question. Nurses reported that the question was easy (12/14) or moderately easy (2/14) to use and was 'easily understood' (6/14) or 'understood after some explanation' (8/14) for most carers. The question demonstrated a high specificity (0.98)/PPV (0.87) but low sensitivity (0.2) when thriving/coping were considered together whereas when thriving was compared with all other responses the sensitivity increased to 0.7. CONCLUSIONS: Single question mental health surveillance appears acceptable to carers and nursing staff and has a high level of specificity for children who are 'struggling' or 'always overwhelmed' versus the SDQ screening measure.

T-stage downstaging of locally advanced rectal cancer after neoadjuvant chemoradiotherapy is not associated with reduced recurrence after adjusting for tumour characteristics.

BACKGROUND AND OBJECTIVES: Prior studies examining prognostic outcomes of locally advanced rectal adenocarcinomas achieving a complete pathological response following neoadjuvant chemoradiotherapy (nCRT) did not adjust for adverse prognostic factors in multivariate analyses and account for magnetic resonance imaging tumour staging inaccuracy pre-nCRT. We aimed to clarify prognostic outcomes in mT3 rectal adenocarcinomas with ypT-downstaging post-nCRT in robust adjusted analyses. METHODS: Retrospective analysis of prospectively-collected clinical data from 528 mT3 rectal adenocarcinomas ≤12 cm from the anal verge, any N-stage, no metastases, post-nCRT following total mesorectal excision (TME). Recurrence outcomes (local and distant combined) of tumours with complete ypT-downstaging (ypT0) post-nCRT before TME compared with no ypT-downstaging (≥ypT3) were examined using multivariate Cox regression, adjusting for confounders and accounting for pre-nCRT mT3-staging inaccuracy using bootstrapping. RESULTS: Complete ypT-downstaging was achieved in of 17.6% tumours and correlated strongly with complete pathological response. Complete ypT-downstaging was not associated with reduced recurrence hazards compared with no ypT-downstaging (hazard ratio = 0.60; 95% confidence interval [CI]: 0.23-1.56; p = 0.30). Lymphovascular invasion (LVI) and ypN+ve increased recurrence hazards by 1.8-fold (95% CI: 1.10-2.79; p = 0.02) and 2.3-fold (95% CI: 1.48-3.54; p = 0.0002), respectively. CONCLUSION: Complete ypT-downstaging was not associated with reduced recurrence after adjusting for confounders and accounting for mT3-staging inaccuracy, even in the absence of adverse prognostic factors (ypN+, LVI).

Corrigendum to: Survey of paediatric telehealth benefits from the caregiver perspective.

Objective This study determined caregivers' evaluations of telehealth consultations for their child, preference over in-person consultations and potential cost savings by child condition, family socioeconomic status and location. Methods A survey was conducted of 2436 caregivers attending a telehealth consultation with their child for a broad group of conditions between 3 June and 25 August 2020 at a tertiary paediatric hospital in Melbourne, Australia. Results Most caregivers found telehealth consultations convenient, acceptable, safe and private, and capable of answering their questions and concerns. However, caregivers who spoke a language other than English and patients attending for behavioural and mental health, developmental or other (e.g. allied health) concerns were more likely to prefer in-person consultations over telehealth. Mean (±s.d.) reported cost savings on caregiver time were A$144.98 ± 99.04 per family per consultation, whereas mean (±s.d.) transport cost savings were A$84.90 ± 100.74 per family per consultation. Cost savings were greatest for families living in low and middle socioeconomic areas and regional or rural areas. Conclusions Paediatric telehealth video consultations were largely viewed favourably by caregivers, except for those attending for behavioural and mental health or developmental concerns. What is known about the topic? Adult consumers of telehealth consultations view them as useful, convenient and cost saving, but less is known about caregivers' evaluations of telehealth consultations and potential cost savings for paediatric patients, and whether these differ by family location, socioeconomic status or child condition. What does this paper add? This is the first Australian paper to report on caregivers' evaluations across a range of paediatric conditions and locations. Most caregivers found telehealth consultations convenient, safe, acceptable, able to answer their questions and concerns about their child's health and cost saving. What are the implications for practitioners? Caregivers of children with behavioural, mental health or developmental problems were less likely to prefer telehealth over in-person consultations, so practitioners should consider providing such consultations in person.

Acting with the future in mind: Testing competing prospective memory interventions.

Prospective memory (PM) is a critical determinant of whether a person is able to lead an independent life. Because PM declines in late adulthood, an important question is therefore whether, and if so, which types, of PM interventions might lead to meaningful benefits. In the present study, we randomly assigned older adults to one of four conditions, in three of which participants received a structured PM intervention (Restorative, Compensatory, and Combined Restorative and Compensatory); the fourth was an Active Control condition. The results showed that there were significant gains on the PM training task used for both the Restorative and Combined conditions. We then analyzed change in PM tasks that were independent of the PM training task (Near Transfer). Only the Combined condition led to post-training improvement. Finally, we analyzed performance on measures of untrained cognitive abilities and everyday functioning: Far transfer effects were not evident for any intervention. These data align with prior literature in showing that interventions that target a single cognitive ability do not reliably generate far transfer effects, and additionally extend our understanding of these effects in two important ways. Firstly, they indicate that, even when the memory challenges that older adults are most concerned about are the direct target of restorative training, transfer effects to untrained cognitive domains may be difficult to achieve. Secondly, they indicate that for older adults whose primary goal is to enhance PM function, combining Restorative and Compensatory approaches is an effective approach.

Patients presenting for hospital-based screening for the coronavirus disease 2019: Risk of disease, and healthcare access preferences.

OBJECTIVE: Early during the coronavirus disease 2019 (COVID-19) pandemic, Australian EDs experienced an unprecedented surge in patients seeking screening. Understanding what proportion of these patients require testing and who can be safely screened in community-based models of care is critical for workforce and infrastructure planning across the healthcare system, as well as public messaging campaigns. METHODS: In this cross-sectional survey, we screened patients presenting to a COVID-19 screening clinic in a tertiary ED. We assessed the proportion of patients who met testing criteria; self-reported symptom severity; reasons why they came to the ED for screening and views on community-based care. RESULTS: We include findings from 1846 patients. Most patients (55.3%) did not meet contemporaneous criteria for testing and most (57.6%) had mild or no (13.4%) symptoms. The main reason for coming to the ED was being referred by a telephone health service (31.3%) and 136 (7.4%) said they tried to contact their general practitioner but could not get an appointment. Only 47 (2.6%) said they thought the disease was too specialised for their general practitioner to manage. CONCLUSIONS: While capacity building in acute care facilities is an important part of pandemic planning, it is also important that patients not needing hospital level of care can be assessed and treated elsewhere. We have identified a significant proportion of people at this early stage in the pandemic who have sought healthcare at hospital but who might have been assisted in the community had services been available and public health messaging structured to guide them there.

Strengthening care for children: pilot of an integrated general practitioner-paediatrician model of primary care in Victoria, Australia.

Objective The aim of this study was to assess the acceptability of a novel, integrated general practitioner (GP)-paediatrician model of care, aiming to reduce referrals to hospitals and improve primary care quality. Methods A pre-post study was conducted with five general practice clinics in north-west Melbourne. Over 12 months, 49 GPs and 896 families participated in the intervention that included weekly to fortnightly paediatrician-GP co-consultation sessions at the general practice, monthly case discussions and telephone or email clinical support for GPs. GPs and families completed surveys or interviews at three time points (before the intervention, after running the model for 4 months and at the end of the implementation). Non-identifiable consultation data were extracted from general practice medical records. Results All GPs found the model acceptable. Although not significant, there was a trend towards a lower proportion of referrals to private paediatricians after the intervention (from 34% to 20%) and emergency departments (from 19% to 12%). Outpatient clinic referrals remained steady, and then increased as the paediatrician left the clinics (31% vs 47% before and after the intervention respectively). Unnecessary prescribing of acid suppression medications decreased by 20% (from 29% to 9%). GPs reported improved confidence in paediatric care (88% vs 100% before and after the intervention respectively). Families reported increased confidence in GP care (78% vs 94% before and after the intervention respectively). Model cost estimates were A$172 above usual care per child seen in the co-consultations. Conclusions This novel model of care is acceptable to GPs and families and may improve access and quality of paediatric care. What is known about the topic? A GP-paediatrician integrated model of care appears effective in reducing hospital burden in England, but has not been implemented in Australia. What does this paper add? This pilot, an Australian first, found that a GP-paediatrician integrated model of care is feasible and acceptable in Australia's primary healthcare system, improves GP confidence and quality of paediatric care, may reduce paediatric referrals to outpatient clinics and emergency departments and improves family confidence in, and preference for, GP care. What are the implications for practitioners? This model may reduce hospital burden and improve quality in GP paediatric care while potentially producing cost savings for families and the healthcare system.

Task characteristics influence facial emotion recognition age-effects: A meta-analytic review.

Relative to their young counterparts, older adults are poorer at recognizing facial expressions. A 2008 meta-analysis of 17 facial emotion recognition data sets showed that these age-related difficulties are not uniform. Rather, they are greatest for the emotions of anger, fear, and sadness, comparative with happiness and surprise, with no age-effect found for disgust. Since then, there have been many methodological advances in assessing emotion recognition. The current comprehensive meta-analysis systematically tested the influence of task characteristics (e.g., photographs vs. videos). The meta-analysis included 102 data sets that compared facial emotion recognition in older and young adult samples (N = 10,526). With task type combined, the pattern of age-effects across emotions was mostly consistent with the previous meta-analysis (i.e., largest age-effects for anger, fear, sadness; no effect for disgust). However, the magnitude and direction of age-effects were strongly influenced by elements of task design. Specifically, videos produced relatively moderate age-effects across all emotions, which indicates that older adults may not exhibit a positivity effect for facial emotion recognition. For disgust recognition, older adults demonstrated superior accuracy to young adults for the most common image set (Pictures of Facial Affect). However, they were poorer than young adults at recognizing this emotion for all other stimulus formats and image sets, which suggests that they do not retain disgust recognition. We discuss the implications that such diversity in the age-effects produced by different facial emotion recognition task designs has for understanding real-world deficits and task selection in future emotion recognition studies.

Small Molecule Inhibitors Limit Endothelial Cell Invasion by Staphylococcus aureus.

Staphylococcus aureus is a leading causative agent in sepsis, endocarditis, and pneumonia. An emerging concept is that prognosis worsens when the infecting S. aureus strain has the capacity to not only colonize tissue as an extracellular pathogen, but to invade host cells and establish intracellular bacterial populations. In previous work, we identified host CDC42 as a central regulator of endothelial cell invasion by S. aureus. In the current work, we report that ML 141, a first-in-class CDC42 inhibitor, decreases invasion and resultant pathogenesis in a dose-dependent and reversible manner. Inhibition was found to be due in part to decreased remodeling of actin that potentially drives endocytic uptake of bacteria/fibronectin/integrin complexes. ML 141 decreased binding to fibronectin at these complexes, thereby limiting a key pathogenic mechanism used by S. aureus to invade. Structural analogs of ML 141 were synthesized (designated as the RSM series) and a subset identified that inhibit invasion through non-cytotoxic and non-bactericidal mechanisms. Our results support the development of adjunctive therapeutics targeting host CDC42 for mitigating invasive infection at the level of the host.
