RESUMO

The NHS 111 service triages over 16,650,745 calls per year and approximately 48% of callers are triaged to a primary care disposition, such as a telephone appointment with a general practitioner (GP). However, there has been little assessment of the ability of primary care services to meet this demand. If a timely service cannot be provided to patients, it could result in patients calling 999 or attending emergency departments (ED) instead. This study aimed to explore the patient journey for callers who were triaged to a primary care disposition, and the ability of primary care services to meet this demand. We obtained routine, retrospective data from the Connected Yorkshire research database, and identified all 111 calls between the 1st January 2021 and 31st December 2021 for callers registered with a GP in the Bradford or Airedale region of West Yorkshire, who were triaged to a primary care disposition. Subsequent healthcare system access (111, 999, primary and secondary care) in the 72 hours following the index 111 call was identified, and a descriptive analysis of the healthcare trajectory of patients was undertaken. There were 56,102 index 111 calls, and a primary care service was the first interaction in 26,690/56,102 (47.6%) of cases, with 15,470/26,690 (58%) commenced within the specified triage time frame. Calls to 999 were higher in the cohort who had no prior contact with primary care (58% vs 42%) as were ED attendances (58.2% vs 41.8), although the proportion of avoidable ED attendances was similar (10.5% vs 11.8%). Less than half of 111 callers triaged to a primary care disposition make contact with a primary care service, and even when they do, call triage time frames are frequently not met, suggesting that current primary care provision cannot meet the demand from 111.

RESUMO

BACKGROUND: Autism Spectrum Disorder (ASD) is a neurodevelopmental disability affecting at least 5 million children in South Asia. Majority of these children are without access to evidence-based care. The UK Pre-school Autism Communication Therapy (PACT) is the only intervention to have shown sustained impact on autism symptoms. It was systematically adapted for non-specialist community delivery in South Asia, as the 'Parent-mediated Autism Social Communication Intervention for non-Specialists (PASS)' and extended 'PASS Plus' interventions. RCTs of both showed feasibility, acceptability and positive effect on parent and child dyadic outcomes. METHODS: The Communication-centred Parent-mediated treatment for Autism Spectrum Disorder in South Asia (COMPASS) trial is now a scale-up two-centre, two-arm single (rater) blinded random allocation parallel group study of the PASS Plus intervention in addition to treatment as usual (TAU) compared to TAU alone, plus health economic evaluation embedded in the India health system. Two hundred forty children (approximately 120 intervention/120 TAU) with ASD aged 2-9 years will be recruited from two tertiary care government hospitals in New Delhi, India. Accredited Social Health Activists will be one of the intervention delivery agents. Families will undertake up to 12 communication sessions over 8 months and will be offered the Plus modules which address coexisting problems. The trial's primary endpoint is at 9 months from randomisation, with follow-up at 15 months. The primary outcome is autism symptom severity; secondary outcomes include parent-child communication, child adaptation, quality of life and parental wellbeing. Primary analysis will follow intention-to-treat principles using linear mixed model regressions with group allocation and repeated measures as random effects. The cost-effectiveness analysis will use a societal perspective over the 15-month period of intervention and follow-up. DISCUSSION: If clinically and cost-effective, this programme will fill an important gap of scalable interventions delivered by non-specialist health workers within the current care pathways for autistic children and their families in low-resource contexts. The programme has been implemented through the COVID-19 pandemic when restrictions were in place; intervention delivery and evaluation processes have been adapted to address these conditions.

RESUMO

Importance: The growing global prevalence of autism spectrum disorder (ASD) is associated with increasing costs for support services. Ascertaining the effects of a successful preemptive intervention for infants showing early behavioral signs of autism on human services budgets is highly policy relevant. Objective: To estimate the net cost impact of the iBASIS-Video Interaction to Promote Positive Parenting (iBASIS-VIPP) intervention on the Australian government. Design, Setting, and Participants: Infants (aged 12 months) showing early behavioral indicators of autism were recruited through community settings into the multicenter Australian iBASIS-VIPP randomized clinical trial (RCT), a 5- to 6-month preemptive parent-mediated intervention, between June 9, 2016, and March 30, 2018, and were followed up for 18 months to age 3 years. This economic evaluation, including cost analysis (intervention and cost consequences) and cost-effectiveness analyses of iBASIS-VIPP compared with usual care (treatment as usual [TAU]), modeled outcomes observed at age 3 through to 12 years (13th birthday) and was conducted from April 1, 2021, to January 30, 2023. Data analysis was conducted from July 1, 2021, to January 29, 2023. Exposures: iBASIS-VIPP intervention. Main Outcomes and Measures: To project the diagnostic trajectory and associated disability support costs drawing on the Australian National Disability Insurance Scheme (NDIS), the main outcome was the differential treatment cost of iBASIS-VIPP plus TAU vs TAU and disability-related government costs modeled to age 12 years, using a clinical diagnosis of ASD and developmental delay (with autism traits) at 3 years. Costs were calculated in Australian dollars and converted to US dollars. Economic performance was measured through the following: (1) differential net present value (NPV) cost (iBASIS-VIPP less TAU), (2) investment return (dollars saved for each dollar invested, taking a third-party payer perspective), (3) break-even age when treatment cost was offset by downstream cost savings, and (4) cost-effectiveness in terms of the differential treatment cost per differential ASD diagnosis at age 3 years. Alternate values of key parameters were modeled in 1-way and probabilistic sensitivity analysis, the latter identifying the likelihood of an NPV cost savings. Results: Of the 103 infants enrolled in the iBASIS-VIPP RCT, 70 (68.0%) were boys. Follow-up data at age 3 years were available for 89 children who received TAU (44 [49.4%]) or iBASIS-VIPP (45 [50.6%]) and were included in this analysis. The estimated mean differential treatment cost was A $5131 (US $3607) per child for iBASIS-VIPP less TAU. The best estimate of NPV cost savings was A $10 695 (US $7519) per child (discounted at 3% per annum). For each dollar invested in treatment, a savings of A $3.08 (US $3.08) was estimated; the break-even cost occurred at age 5.3 years (approximately 4 years after intervention delivery). The mean differential treatment cost per lower incident case of ASD was A $37 181 (US $26 138). We estimated that there was an 88.9% chance that iBASIS-VIPP would deliver a cost savings for the NDIS, the dominant third-party payer. Conclusions and Relevance: The results of this study suggest that iBASIS-VIPP represents a likely good-value societal investment for supporting neurodivergent children. The estimated net cost savings were considered conservative, as they covered only third-party payer costs incurred by the NDIS and outcomes were modeled to just age 12 years. These findings further suggest that preemptive interventions may be a feasible, effective, and efficient new clinical pathway for ASD, reducing disability and the costs of support services. Long-term follow-up of children receiving preemptive intervention is needed to confirm the modeled results.

RESUMO

BACKGROUND: The economic burden of autism is substantial and includes a range of costs, including healthcare, education, productivity losses, informal care and respite care, among others. In India, approximately, 2 million children aged 2-9 years have autism. Given the likely substantial burden of illness and the need to identify effective and cost-effective interventions, this research aimed to produce a comprehensive cost of illness inventory (COII) suitable for children with autism in South Asia (India) to support future research. METHODS: A structured and iterative design process was followed to create the COII, including literature reviews, interviews with caregivers, pilot testing and translation. Across the development of the COII, thirty-two families were involved in the design and piloting of the tool. The COII was forward translated (from English to Hindi) and back translated. Each stage of the process of development of the COII resulted in the further refinement of the tool. RESULTS: Domains covered in the final COII include education, childcare, relocation, healthcare contacts (outpatient, inpatient, medical emergencies, investigations and medication), religious retreats and rituals, specialist equipment, workshops and training, special diet, support and care, certification, occupational adjustments and government rebates/schemes. Administration and completion of the COII determined it to be feasible to complete in 35 minutes by qualified and trained researchers. The final COII is hosted by REDCap Cloud and is a bilingual instrument (Hindi and English). CONCLUSIONS: The COII was developed using experiences gathered from an iterative process in a metropolitan area within the context of one low- and middle-income country (LMIC) setting, India. Compared to COII tools used for children with autism in high-income country settings, additional domains were required, such as complimentary medication (e.g. religious retreats and homeopathy). The COII will allow future research to quantify the cost of illness of autism in India from a broad perspective and will support relevant economic evaluations. Understanding the process of developing the questionnaire will help researchers working in LMICs needing to adapt the current COII or developing similar questionnaires.

RESUMO

BACKGROUND: Autism is a neurodevelopmental disability affecting over 1% of UK children. The period following a child's autism diagnosis can present real challenges in adaptation for families. Twenty to 50% of caregivers show clinically significant levels of mental health need within the post-diagnostic period and on an ongoing basis. Best practice guidelines recommend timely post-diagnostic family support. Current provision is patchy, largely unevidenced, and a source of dissatisfaction for both families and professionals. There is a pressing need for an evidenced programme of post-diagnostic support focusing on caregiver mental health and adjustment, alongside autism psycho-education. This trial tests the clinical and cost-effectiveness of a new brief manualised psychosocial intervention designed to address this gap. METHODS: This is a multi-centre two-parallel-group single (researcher)-blinded randomised controlled trial of the Empower-Autism programme plus treatment-as-usual versus usual local post-diagnostic offer plus treatment-as-usual. Caregivers of children aged 2-15 years with a recent autism diagnosis will be recruited from North West England NHS or local authority centres. Randomisation is individually by child, with one "index" caregiver per child, stratified by centre, using 2:1 randomisation ratio to assist recruitment and timely intervention. Empower-Autism is a group-based, manualised, post-diagnostic programme that combines autism psycho-education and psychotherapeutic components based on Acceptance and Commitment Therapy to support caregiver mental health, stress management and adjustment to their child's diagnosis. The comparator is any usual local group-based post-diagnostic psycho-education offer. Receipt of services will be specified through health economic data. PRIMARY OUTCOME: caregiver mental health (General Health Questionnaire-30) at 52-week follow-up. SECONDARY OUTCOMES: key caregiver measures (wellbeing, self-efficacy, adjustment, autism knowledge) at 12-, 26- and 52-week follow-up and family and child outcomes (wellbeing and functioning) at 52-week endpoint. SAMPLE: N=380 (approximately 253 intervention/127 treatment-as-usual). Primary analysis will follow intention-to-treat principles using linear mixed models with random intercepts for group membership and repeated measures. Cost-effectiveness acceptability analyses will be over 52 weeks, with decision modelling to extrapolate to longer time periods. DISCUSSION: If effective, this new approach will fill a key gap in the provision of evidence-based care pathways for autistic children and their families. TRIAL REGISTRATION: ISRCTN 45412843 . Prospectively registered on 11 September 2019.

RESUMO

INTRODUCTION: Suicide is a global health concern. Sociocultural factors have an impact on self-harm and suicide rates. In Pakistan, both self-harm and suicide are considered as criminal offence's and are condemned on both religious and social grounds. The proposed intervention 'Youth Culturally Adapted Manual Assisted Problem Solving Training (YCMAP)' is based on principles of problem-solving and cognitive-behavioural therapy. YCMAP is a brief, culturally relevant, scalable intervention that can be implemented in routine clinical practice if found to be effective. METHOD AND ANALYSIS: A multicentre rater blind randomised controlled trial to evaluate the clinical and cost-effectiveness of YCMAP including a sample of 652 participants, aged 12-18 years, presenting to general physicians/clinicians, emergency room after self harm or self referrals. We will test the effectiveness of 8-10 individual sessions of YCMAP delivered over 3 months compared with treatment as usual. Primary outcome measure is repetition of self-harm at 12 months. The seconday outcomes include reduction in suicidal ideation, hopelessness and distress and improvement in health related quality of life. Assessments will be completed at baseline, 3, 6, 9 and 12 months postrandomisation. The nested qualitative component will explore perceptions about management of self-harm and suicide prevention among adolescents and investigate participants' experiences with YCMAP. The study will be guided by the theory of change approach to ensure that the whole trial is centred around needs of the end beneficiaries as key stakeholders in the process. ETHICS AND DISSEMINATION: Ethics approval has been obtained from the Ethics Committee of University of Manchester, the National Bioethics Committee in Pakistan. The findings of this study will be disseminated through community workshops, social media, conference presentations and peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT04131179.

RESUMO

BACKGROUND: Autism presents with similar prevalence and core impairments in diverse populations. We conducted a scoping review of reviews to determine key barriers and innovative strategies which can contribute to attaining universal health coverage (UHC), from early detection to effective interventions for autism in low- and middle-income countries (LAMIC). METHODS: A systematic literature search of review articles was conducted. Reviews relevant to the study research question were included if they incorporated papers from LAMIC and focused on children (

RESUMO

BackgroundWhole genome sequencing (WGS) is increasingly used for pathogen identification and surveillance.AimWe evaluated costs and benefits of routine WGS through case studies at eight reference laboratories in Europe and the Americas which conduct pathogen surveillance for avian influenza (two laboratories), human influenza (one laboratory) and food-borne pathogens (five laboratories).MethodsThe evaluation focused on the institutional perspective, i.e. the 'investment case' for implementing WGS compared with conventional methods, based on costs and benefits during a defined reference period, mostly covering at least part of 2017. A break-even analysis estimated the number of cases of illness (for the example of Salmonella surveillance) that would need to be avoided through WGS in order to 'break even' on costs.ResultsOn a per-sample basis, WGS was between 1.2 and 4.3 times more expensive than routine conventional methods. However, WGS brought major benefits for pathogen identification and surveillance, substantially changing laboratory workflows, analytical processes and outbreaks detection and control. Between 0.2% and 1.1% (on average 0.7%) of reported salmonellosis cases would need to be prevented to break even with respect to the additional costs of WGS.ConclusionsEven at cost levels documented here, WGS provides a level of additional information that more than balances the additional costs if used effectively. The substantial cost differences for WGS between reference laboratories were due to economies of scale, degree of automation, sequencing technology used and institutional discounts for equipment and consumables, as well as the extent to which sequencers are used at full capacity.

RESUMO

BACKGROUND: Quality of life for children and adolescents living with serious parental mental illness can be impaired, but evidence-based interventions to improve it are scarce. OBJECTIVE: Co-production of a child-centred intervention [called Young Simplifying Mental Illness plus Life Enhancement Skills (SMILES)] to improve the health-related quality of life of children and adolescents living with serious parental mental illness, and evaluating its acceptability and feasibility for delivery in NHS and community settings. DESIGN: Qualitative and co-production methods informed the development of the intervention (Phase I). A feasibility randomised controlled trial was designed to compare Young SMILES with treatment as usual (Phase II). Semistructured qualitative interviews were used to explore acceptability among children and adolescents living with their parents, who had serious mental illness, and their parents. A mixture of semistructured qualitative interviews and focus group research was used to examine feasibility among Young SMILES facilitators and referrers/non-referrers. SETTING: Randomisation was conducted after baseline measures were collected by the study co-ordinator, ensuring that the blinding of the statistician and research team was maintained to reduce detection bias. PARTICIPANTS: Phase I: 14 children and adolescents living with serious parental mental illness, seven parents and 31 practitioners from social, educational and health-related sectors. Phase II: 40 children and adolescents living with serious parental mental illness, 33 parents, five referrers/non-referrers and 16 Young SMILES facilitators. INTERVENTION: Young SMILES was delivered at two sites: (1) Warrington, supported by the National Society for the Prevention of Cruelty to Children (NSPCC), and (2) Newcastle, supported by the NHS and Barnardo's. An eight-session weekly group programme was delivered, with four to six children and adolescents living with serious parental mental illness per age-appropriate group (6-11 and 12-16 years). At week 4, a five-session parallel weekly programme was offered to the parents/carers. Sessions lasted 2 hours each and focused on improving mental health literacy, child-parent communication and children's problem-solving skills. MAIN OUTCOME MEASURES: Phase ll children and parents completed questionnaires at randomisation and then again at 4 and 6 months post randomisation. Quality of life was self-reported by children and proxy-reported by parents using the Paediatric Quality of Life questionnaire and KIDSCREEN. Semistructured interviews with parents (n = 14) and children (n = 17) who participated in the Young SMILES groups gathered information about their motivation to sign up to the study, their experiences of participating in the group sessions, and their perceived changes in themselves and their family members following intervention. Further interviews with individual referrers (n = 5) gathered information about challenges to recruitment and randomisation. Two focus groups (n = 16) with practitioners who facilitated the intervention explored their views of the format and content of the Young SMILES manual and their suggestions for changes. RESULTS: A total of 35 families were recruited: 20 were randomly allocated to Young SMILES group and 15 to treatment as usual. Of those, 28 families [15/20 (75%) in the intervention group and 13/15 (87%) in the control group] gave follow-up data at the primary end point (4 months post baseline). Participating children had high adherence to the intervention and high completion rates of the questionnaires. Children and adolescents living with their parents, who had serious mental illness, and their parents were mainly very positive and enthusiastic about Young SMILES, both of whom invoked the benefits of peer support and insight into parental difficulties. Although facilitators regarded Young SMILES as a meaningful and distinctive intervention having great potential, referrers identified several barriers to referring families to the study. One harm was reported by a parent, which was dealt with by the research team and the NSPCC in accordance with the standard operating procedures. LIMITATIONS: The findings from our feasibility study are not sufficient to recommend a fully powered trial of Young SMILES in the near future. Although it was feasible to randomise children and adolescents living with serious parental mental illness of different ages to standardised, time-limited groups in both NHS and non-NHS settings, an intervention like Young SMILES is unlikely to address underlying core components of the vulnerability that children and adolescents living with serious parental mental illness express as a population over time. CONCLUSIONS: Young SMILES was widely valued as unique in filling a recognised gap in need. Outcome measures in future studies of interventions for children and adolescents living with serious parental mental illness are more likely to capture change in individual risk factors for reduced quality of life by considering their unmet need, rather than on an aggregate construct of health-related quality of life overall, which may not reflect these young people's needs. FUTURE WORK: A public health approach to intervention might be best. Most children and adolescents living with serious parental mental illness remain well most of the time, so, although their absolute risks are low across outcomes (and most will remain resilient most of the time), consistent population estimates find their relative risk to be high compared with unexposed children. A public health approach to intervention needs to be both tailored to the particular needs of children and adolescents living with serious parental mental illness and agile to these needs so that it can respond to fluctuations over time.

Children and adolescents living with serious parental mental illness are at increased risk of poorer mental, physical and emotional health but few services are available to them. We worked with young people, parents and professionals to co-develop a community-based intervention called Young Simplifying Mental Illness plus Life Enhancement Skills (SMILES). This involves eight children's sessions over 8 weeks in two age groups (6­11 and 12­16 years) and five separate parent sessions. Each session includes activities designed to improve understanding of mental illness, communication between children and parents, and problem-solving. To assess the feasibility and how acceptable Young SMILES is to those who received (and delivered) the intervention, we recruited 35 families: 20 were offered Young SMILES and 15 continued to receive their usual care. Children and parents completed questionnaires when they entered the research and then after 4 and 6 months. Children and adolescents living with serious parental mental illness assigned to either Young SMILES or usual-care groups reported that their quality of life, mental health, day-to-day functioning and knowledge of mental illness was similar to that of their population peers. Answers to parental questionnaires suggested that overall our participants' parenting style was positive and their levels of stress were as expected for parents in general. Across questionnaires, parents underestimated their children's quality of life and overestimated their difficulties. Children and adolescents living with serious parental mental illness and parents were mainly very positive and enthusiastic about Young SMILES. They liked getting together to discuss their experiences with others in similar situations, but some parents felt unprepared to do this. Children liked having something that focused on their own needs separately from those of their parents; they liked the fun activities and valued the time away from their parents, but also wanted their parents to have support. Facilitators and referrers saw great value in Young SMILES. The needs of children with mentally ill parents remain unmet in the current system; a future evaluation of Young SMILES needs to reconsider the primary outcome and start with a pilot trial with clear criteria for progression to a full trial.

RESUMO

Male-only parental care, while rare in most animals, is a widespread strategy within teleost fish. The costs and benefits to males of acting as sole carer are highly variable among fish species making it challenging to determine the selective pressures driving the evolution of male-only care to such a high prevalence. We conducted a phylogenetic meta-analysis to examine the costs and benefits of paternal care across fish species. We found no evidence that providing care negatively affects male condition. In contrast with other taxa, we also found limited evidence that male care has evolved as a strategy to improve offspring survival. Instead, we found that males already caring for a brood are preferred by females and that this preference is strongest in those species in which males work harder to care for larger broods. Thus, in fish, investment in offspring care does not constrain a male's mating success but rather augments it, suggesting that the relatively high prevalence of male-only care in fish may be in part explained by sexual selection through female preference for caring males.

RESUMO

Inbreeding is often avoided in natural populations by passive processes such as sex-biased dispersal. But, in many social animals, opposite-sexed adult relatives are spatially clustered, generating a risk of incest and hence selection for active inbreeding avoidance. Here we show that, in long-tailed tits (Aegithalos caudatus), a cooperative breeder that risks inbreeding by living alongside opposite-sex relatives, inbreeding carries fitness costs and is avoided by active kin discrimination during mate choice. First, we identified a positive association between heterozygosity and fitness, indicating that inbreeding is costly. We then compared relatedness within breeding pairs to that expected under multiple mate-choice models, finding that pair relatedness is consistent with avoidance of first-order kin as partners. Finally, we show that the similarity of vocal cues offers a plausible mechanism for discrimination against first-order kin during mate choice. Long-tailed tits are known to discriminate between the calls of close kin and nonkin, and they favor first-order kin in cooperative contexts, so we conclude that long-tailed tits use the same kin discrimination rule to avoid inbreeding as they do to direct help toward kin.

RESUMO

The introduction of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) was accompanied by the elimination of the Global Assessment of Functioning (GAF) scale, which was previously used to assess functioning. Although the World Health Organization Disability Assessment Schedule, Version 2.0 (WHODAS 2.0) was offered as a measure for further study, widespread adoption of the WHODAS 2.0 has yet to occur. The lack of a standardized instrument for assessing posttraumatic stress disorder (PTSD)-related disability has important implications for disability compensation. Accordingly, this study was designed to determine and codify the utility of the WHODAS 2.0 for assessing PTSD-related disability. Veterans from several VA medical centers (N = 1109) were included. We examined PTSD using several definitions and modalities and considered results by gender and age. Across definitions and modalities, veterans with PTSD reported significantly greater WHODAS 2.0 total (large effects; all ts > 6.00; all ps < .01; all Cohen's ds > 1.03) and subscale (medium-to-large effects; all ts > 2.29; all ps < .05; all Cohen's ds > .39) scores than those without PTSD. WHODAS 2.0 scores did not vary by gender; however, younger veterans reported less disability than older veterans (small effects; all Fs > 4.30; all ps < .05; all η2s < .05). We identified 32 as the optimally efficient cutoff score for discriminating veterans with and without PTSD-related disability, although this varied somewhat by age and gender. Findings support the utility of the WHODAS 2.0 in assessing PTSD-related disability.

RESUMO

Parasites have profound fitness effects on their hosts, yet these are often sub-lethal, making them difficult to understand and quantify. A principal sub-lethal mechanism that reduces fitness is parasite-induced increase in energetic costs of specific behaviours, potentially resulting in changes to time and energy budgets. However, quantifying the influence of parasites on these costs has not been undertaken in free-living animals. We used accelerometers to estimate energy expenditure on flying, diving and resting, in relation to a natural gradient of endo-parasite loads in a wild population of European shags Phalacrocorax aristotelis We found that flight costs were 10% higher in adult females with higher parasite loads and these individuals spent 44% less time flying than females with lower parasite loads. There was no evidence for an effect of parasite load on daily energy expenditure, suggesting the existence of an energy ceiling, with the increase in cost of flight compensated for by a reduction in flight duration. These behaviour specific costs of parasitism will have knock-on effects on reproductive success, if constraints on foraging behaviour detrimentally affect provisioning of young. The findings emphasize the importance of natural parasite loads in shaping the ecology and life-history of their hosts, which can have significant population level consequences.

RESUMO

BACKGROUND: Self-harm in adolescents is common and repetition rates high. There is limited evidence of the effectiveness of interventions to reduce self-harm. OBJECTIVES: To assess the clinical effectiveness and cost-effectiveness of family therapy (FT) compared with treatment as usual (TAU). DESIGN: A pragmatic, multicentre, individually randomised controlled trial of FT compared with TAU. Participants and therapists were aware of treatment allocation; researchers were blind to allocation. SETTING: Child and Adolescent Mental Health Services (CAMHS) across three English regions. PARTICIPANTS: Young people aged 11-17 years who had self-harmed at least twice presenting to CAMHS following self-harm. INTERVENTIONS: Eight hundred and thirty-two participants were randomised to manualised FT delivered by trained and supervised family therapists (n = 415) or to usual care offered by local CAMHS following self-harm (n = 417). MAIN OUTCOME MEASURES: Rates of repetition of self-harm leading to hospital attendance 18 months after randomisation. RESULTS: Out of 832 young people, 212 (26.6%) experienced a primary outcome event: 118 out of 415 (28.4%) randomised to FT and 103 out of 417 (24.7%) randomised to TAU. There was no evidence of a statistically significant difference in repetition rates between groups (the hazard ratio for FT compared with TAU was 1.14, 95% confidence interval 0.87 to 1.49; p = 0.3349). FT was not found to be cost-effective when compared with TAU in the base case and most sensitivity analyses. FT was dominated (less effective and more expensive) in the complete case. However, when young people's and caregivers' quality-adjusted life-year gains were combined, FT incurred higher costs and resulted in better health outcomes than TAU within the National Institute for Health and Care Excellence cost-effectiveness range. Significant interactions with treatment, indicating moderation, were detected for the unemotional subscale on the young person-reported Inventory of Callous-Unemotional Traits (p = 0.0104) and the affective involvement subscale on the caregiver-reported McMaster Family Assessment Device (p = 0.0338). Caregivers and young people in the FT arm reported a range of significantly better outcomes on the Strengths and Difficulties Questionnaire. Self-reported suicidal ideation was significantly lower in the FT arm at 12 months but the same in both groups at 18 months. No significant unexpected adverse events or side effects were reported, with similar rates of expected adverse events across trial arms. CONCLUSIONS: For adolescents referred to CAMHS after self-harm, who have self-harmed at least once before, FT confers no benefits over TAU in reducing self-harm repetition rates. There is some evidence to support the effectiveness of FT in reducing self-harm when caregivers reported poor family functioning. When the young person themselves reported difficulty expressing emotion, FT did not seem as effective as TAU. There was no evidence that FT is cost-effective when only the health benefits to participants were considered but there was a suggestion that FT may be cost-effective if health benefits to caregivers are taken into account. FT had a significant, positive impact on general emotional and behavioural problems at 12 and 18 months. LIMITATIONS: There was significant loss to follow-up for secondary outcomes and health economic analyses; the primary outcome misses those who do not attend hospital following self-harm; and the numbers receiving formal FT in the TAU arm were higher than expected. FUTURE WORK: Evaluation of interventions targeted at subgroups of those who self-harm, longer-term follow-up and methods for evaluating health benefits for family groups rather than for individuals. TRIAL REGISTRATION: Current Controlled Trials ISRCTN59793150.

RESUMO

There is a lack of measures that reflect the intervention priorities of parents of children with autism spectrum disorder (ASD) and that assess the impact of interventions on family experience and quality of life. The Autism Family Experience Questionnaire (AFEQ) was developed through focus groups and online consultation with parents, and reflected parental priorities. It was then administered to the parents of children enrolled in the Pre-school Autism Communication Trial and its 6-year follow-up study. The AFEQ showed good convergent validity with well-established measures of child adaptive functioning, parental mental health and parental wellbeing. It was sensitive to change in response to a parent-mediated intervention for young children with autism, showing treatment effect at treatment endpoint which increased at six-year follow-up.

RESUMO

Several known risk factors for nonsuicidal self-injury (NSSI), such as negative emotionality and deficits in emotion skills, are also associated with masculinity. Researchers and clinicians suggest that masculine norms around emotional control and self-reliance may make men more likely to engage in self-harm. Masculinity has also been implicated as a potential risk factor for suicide and other self-damaging behaviors. However, the association between masculinity and NSSI has yet to be explored. In the current study, a sample of 912 emerging adults from two universities in the Northeastern United States completed a web-based questionnaire assessing adherence to masculine norms, engagement in NSSI, and known risk factors for NSSI (demographics and number of self-injurers known). Stronger adherence to masculine norms predicted chronic NSSI (five or more episodes throughout the life span) above and beyond other known risk factors. Adherence to masculine norms was related to methods of NSSI. Clinical implications are discussed, including discussions of masculine norms in treatment settings. Future research should examine what specific masculine norms are most closely linked to NSSI and other self-damaging behaviors.

RESUMO

INTRODUCTION: More than half of all patients attended by the South Western Ambulance Service NHS Foundation Trust are over the age of 65. In 2017, 62% of older patients who were the subject of a frailty assessment were believed to have at least mild frailty (1/5 of all patients). Frailty is an increasingly relevant concept/diagnosis and ambulance services are well positioned to identify frailty and influence the 'care pathways' through which patients are directed (thereby influencing health outcomes). Throughout the South Western Ambulance Service NHS Foundation Trust, a mandatory training session regarding frailty was delivered to clinical personnel in 2017 and frailty assessment tools are available on the electronic Patient Clinical Record. AIM: To explore and gain insight into the current knowledge, practice and attitudes of ambulance clinicians regarding frailty and patients with frailty. METHODS: Two focus groups of ambulance clinicians (n = 8; n = 9) recruited from across the South Western Ambulance Service NHS Foundation Trust were held in October 2017. Focus group discussions were analysed thematically. RESULTS: Knowledge of conceptual models of frailty, appropriate assessment of patients with frailty and appropriate care pathways varied substantially among focus group participants. Completion of the 'Rockwood' Clinical Frailty Scale for relevant patients has become routine. However, conflicting opinions were expressed regarding the context and purpose of this. The Timed-Up-and-Go mobility assessment tool is also on the electronic Patient Clinical Record, but difficulties regarding its completion were expressed.Patient management strategies ranged from treatment options which the ambulance service can provide, to referrals to primary/community care which can support the management of patients in their homes, and options to refer patients directly to hospital units or specialists with the aim of facilitating appropriate assessment, treatment and discharge. Perceptions of limited availability and geographical variability regarding these referral pathways was a major feature of the discussions, raising questions regarding awareness, capacity, inter-professional relationships and patient choice. CONCLUSION: Knowledge, practice and attitudes of ambulance staff, with regard to frailty, varied widely. This reflected the emerging nature of the condition, both academically and clinically, within the ambulance profession and the wider healthcare system.

RESUMO

Objectives To examine temporal trends in sex and age specific incidence of self harm in children and adolescents, clinical management patterns, and risk of cause specific mortality following an index self harm episode at a young age.Design Population based cohort study.Setting UK Clinical Practice Research Datalink-electronic health records from 647 general practices, with practice level deprivation measured ecologically using the index of multiple deprivation. Patients from eligible English practices were linked to hospital episode statistics (HES) and Office for National Statistics (ONS) mortality records.Participants For the descriptive analytical phases we examined data pertaining to 16 912 patients aged 10-19 who harmed themselves during 2001-14. For analysis of cause specific mortality following self harm, 8638 patients eligible for HES and ONS linkage were matched by age, sex, and general practice with up to 20 unaffected children and adolescents (n=170 274).Main outcome measures In the first phase, temporal trends in sex and age specific annual incidence were examined. In the second phase, clinical management was assessed according to the likelihood of referral to mental health services and psychotropic drug prescribing. In the third phase, relative risks of all cause mortality, unnatural death (including suicide and accidental death), and fatal acute alcohol or drug poisoning were estimated as hazard ratios derived from stratified Cox proportional hazards models for the self harm cohort versus the matched unaffected comparison cohort.Results The annual incidence of self harm was observed to increase in girls (37.4 per 10 000) compared with boys (12.3 per 10 000), and a sharp 68% increase occurred among girls aged 13-16, from 45.9 per 10 000 in 2011 to 77.0 per 10 000 in 2014. Referrals within 12 months of the index self harm episode were 23% less likely for young patients registered at the most socially deprived practices, even though incidences were considerably higher in these localities. Children and adolescents who harmed themselves were approximately nine times more likely to die unnaturally during follow-up, with especially noticeable increases in risks of suicide (deprivation adjusted hazard ratio 17.5, 95% confidence interval 7.6 to 40.5) and fatal acute alcohol or drug poisoning (34.3, 10.2 to 115.7).Conclusions Gaining a better understanding of the mechanisms responsible for the recent apparent increase in the incidence of self harm among early-mid teenage girls, and coordinated initiatives to tackle health inequalities in the provision of services to distressed children and adolescents, represent urgent priorities for multiple public agencies.

RESUMO

Two main techniques have dominated the field of ecological energetics: the heart rate and doubly labelled water methods. Although well established, they are not without their weaknesses, namely expense, intrusiveness and lack of temporal resolution. A new technique has been developed using accelerometers; it uses the overall dynamic body acceleration (ODBA) of an animal as a calibrated proxy for energy expenditure. This method provides high-resolution data without the need for surgery. Significant relationships exist between the rate of oxygen consumption (V̇O2 ) and ODBA in controlled conditions across a number of taxa; however, it is not known whether ODBA represents a robust proxy for energy expenditure consistently in all natural behaviours and there have been specific questions over its validity during diving, in diving endotherms. Here, we simultaneously deployed accelerometers and heart rate loggers in a wild population of European shags (Phalacrocorax aristotelis). Existing calibration relationships were then used to make behaviour-specific estimates of energy expenditure for each of these two techniques. Compared with heart rate-derived estimates, the ODBA method predicts energy expenditure well during flight and diving behaviour, but overestimates the cost of resting behaviour. We then combined these two datasets to generate a new calibration relationship between ODBA and V̇O2  that accounts for this by being informed by heart rate-derived estimates. Across behaviours we found a good relationship between ODBA and V̇O2 Within individual behaviours, we found useable relationships between ODBA and V̇O2  for flight and resting, and a poor relationship during diving. The error associated with these new calibration relationships mostly originates from the previous heart rate calibration rather than the error associated with the ODBA method. The equations provide tools for understanding how energy constrains ecology across the complex behaviour of free-living diving birds.

RESUMO

BACKGROUND: Gun buyback programs represent one arm of a multipronged approach to raise awareness and education about gun safety. METHODS: The city of Worcester, MA has conducted an annual gun buyback at the Police Department Headquarters since 2002. We analyzed survey responses from a voluntary, 18-question, face-to-face structured interview from December 2009 to June 2015 using descriptive statistics to determine participant demographics and motivations for participation. RESULTS: A total of 943 guns were collected, and 273 individuals completed surveys. The majority of participants were white males older than 55years (42.4%). Participants represented 61 zip codes across Worcester County, with 68% having prior gun safety training and 61% with weapons remaining in the home (27% of which children could potentially access). The top reasons for turning in guns were "no longer needed" (48%) and "fear of children accessing the gun" (14%). About 1 in 3 respondents knew someone injured/killed by gun violence. Almost all (96%) respondents claimed the program raised community awareness of firearm risk. CONCLUSION: The Worcester Goods for Guns Buyback has collected more than 900 guns between 2009 and 2015. The buyback removes unwanted guns from homes and raises community awareness about firearm safety.
