A clinical investigation of chronic pain in subjects with HIV-associated sensory neuropathy

HIV-associated sensory neuropathy (HIV-SN) is a debilitating complication of HIV infection and its treatment. However, no commercially available pharmacotherapy has demonstrated consistent efficacy at clinical trial. This study aims to identify strategies to improve clinical trial design in HIV-SN by deeply phenotyping a cohort of people living with HIV, and through a meta-analysis of the placebo response in HIV-SN trials. 148 subjects were recruited, including 81 with HIV-SN. Age was the only independent predictor of neuropathy in this cohort. The prevalence of multiple chronic pain diagnoses was high, especially in those with HIV-SN (82.5% versus 61.2%, p=0.0008). This indicates that careful characterisation of painful conditions at trial entry is required to identify efficacy of the intervention with respect to HIV-SN-related symptoms specifically. Subjects showed heterogeneity of symptoms and signs, determined by symptom-based questionnaires and quantitative sensory testing, and could be allocated to distinct ‘sensory profiles’. Those with HIV-SN displayed predominantly ‘mechanical hyperalgesia’ (43.2%) and ‘sensory loss’ (30.3%) profiles. Similar profiling at clinical trial enrolment could allow for the identification of differential responses to therapy at a sub-group level. A preliminary healthy volunteer study allowed for assessment of reliability and measurement error in conditioned pain modulation (CPM). There was no difference in CPM response between those with and without neuropathy, but the response was heterogeneous. CPM may not yet be robust enough to recommend as a profiling measure in trials of HIV-SN. Corneal confocal microscopy and a point-of-care nerve conduction device were assessed for their effectiveness as tools for screening and monitoring HIV-SN. Both were shown to be useful and have the potential to increase the certainty of a diagnosis of neuropathic pain at trial enrolment. A 2012 meta-analysis identified a greater placebo response in trials of HIV-SN compared to other neuropathic pain conditions. Repeat meta-analysis identified no difference in placebo response between HIV-SN and a comparable sensory neuropathy, diabetic polyneuropathy.Open Acces

The Second Victims: A Grounded Theory explanation of the experience and impact of traumatic births amongst midwives and obstetricians

Aim: Midwives, and obstetricians may be at increased risk of becoming “Second Victims” (SVs) due to increased exposure to severe medical events. However, current evidence exploring their experiences of adverse events is sparse. The current study aims to better understand the perception and impact of traumatic perinatal events amongst midwives and obstetricians, and to generate clear theoretical frameworks that can be translated into clinical settings. Method: Eight midwives and six obstetricians working within the NHS were interviewed about their experiences of traumatic perinatal events. Semi-structured interviews were conducted and analysed using constructivist Grounded Theory (Charmaz, 2008). Results: Two theoretical frameworks emerged from the data. Six main themes reflected participants’ experiences: traumatic births; exacerbating factors; buffering factors; the aftermath; position in hierarchical system; and cultural change. Conclusion: The study provided novel insights, revealing similarities and differences between midwives’ and obstetrician’s experiences of traumatic events. Position in hierarchical system was influential in the differences observed. In both groups, organisational factors contributed significantly to the perception and impact of traumatic events. Maternity organisations have the power to reduce the risk the “Second Victim” (SV) phenomenon amongst staff and mitigate potential consequences to the mothers' birthing experience

The effectiveness and cost-effectiveness of first aid interventions for burns given to caregivers of children: A systematic review

Objectives: the effectiveness and cost-effectiveness of burns first-aid educational interventions given to caregivers of children. Methods: Systematic review of eligible studies from seven databases, international journals, trials repositories and contacted international experts. Results: Of 985 potential studies, four met the inclusion criteria. All had high risk of bias and weak global rating. Two studies identified a statistically significant increase in knowledge after of a media campaign. King et al. (41.7% vs 63.2%, p<0.0001), Skinner et al. (59% vs 40%, p=0.004). Skinner et al. also identified fewer admissions (64.4% vs 35.8%, p<0.001) and surgical procedures (25.6% vs 11.4%, p<0.001). Kua et al. identified a significant improvement in caregiver’s knowledge (22.9% vs 78.3%, 95% CI 49.2, 61.4) after face-to-face education intervention. Ozyazicioglu et al. evaluated the effect of a first-aid training program and showed a reduction in use of harmful traditional methods for burns in children (29% vs 16.1%, p<0.001). No data on cost-effectiveness was identified. Conclusion: There is a paucity of high quality research in this field and considerable heterogeneity across the included studies. Delivery and content of interventions varied. However, studies showed a positive effect on knowledge. No study evaluated the direct effect of the intervention on first aid administration. High quality clinical trials are needed

Factors influencing child protection professionals' decision-making and multidisciplinary collaboration in suspected abusive head trauma cases: a qualitative study

Clinicians face unique challenges when assessing suspected child abuse cases. The majority of the literature exploring diagnostic decision-making in this field is anecdotal or survey-based and there is a lack of studies exploring decision-making around suspected abusive head trauma (AHT). We aimed to determine factors influencing decision-making and multidisciplinary collaboration in suspected AHT cases, amongst 56 child protection professionals. Semi-structured interviews were conducted with clinicians (25), child protection social workers (10), legal practitioners (9, including 4 judges), police officers (8), and pathologists (4), purposively sampled across southwest United Kingdom. Interviews were recorded, transcribed and imported into NVivo for thematic analysis (38% double-coded). We identified six themes influencing decision-making: ‘professional’, ‘medical’, ‘circumstantial’, ‘family’, ‘psychological’ and ‘legal’ factors. Participants diagnose AHT based on clinical features, the history, and the social history, after excluding potential differential diagnoses. Participants find these cases emotionally challenging but are aware of potential biases in their evaluations and strive to overcome these. Barriers to decision-making include lack of experience, uncertainty, the impact on the family, the pressure of making the correct diagnosis, and disagreements between professionals. Legal barriers include alternative theories of causation proposed in court. Facilitators include support from colleagues and knowledge of the evidence-base. Participants’ experiences with multidisciplinary collaboration are generally positive, however child protection social workers and police officers are heavily reliant on clinicians to guide their decision-making, suggesting the need for training on the medical aspects of physical abuse for these professionals and multidisciplinary training that provides knowledge about the roles of each agency

Acceptability of the Predicting Abusive Head Trauma (PredAHT) clinical prediction tool: A qualitative study with child protection professionals

The validated Predicting Abusive Head Trauma (PredAHT) tool estimates the probability of abusive head trauma (AHT) based on combinations of six clinical features: head/neck bruising; apnea; seizures; rib/long-bone fractures; retinal hemorrhages. We aimed to determine the acceptability of PredAHT to child protection professionals. We conducted qualitative semi-structured interviews with 56 participants: clinicians (25), child protection social workers (10), legal practitioners (9, including 4 judges), police officers (8), and pathologists (4), purposively sampled across southwest United Kingdom. Interviews were recorded, transcribed and imported into NVivo for thematic analysis (38% double-coded). We explored participants’ evaluations of PredAHT, their opinions about the optimal way to present the calculated probabilities, and their interpretation of probabilities in the context of suspected AHT. Clinicians, child protection social workers and police thought PredAHT would be beneficial as an objective adjunct to their professional judgment, to give them greater confidence in their decisions. Lawyers and pathologists appreciated its value for prompting multidisciplinary investigations, but were uncertain of its usefulness in court. Perceived disadvantages included: possible over-reliance and false reassurance from a low score. Interpretations regarding which percentages equate to ‘low’, ‘medium’ or ‘high’ likelihood of AHT varied; participants preferred a precise % probability over these general terms. Participants would use PredAHT with provisos: if they received multi-agency training to define accepted risk thresholds for consistent interpretation; with knowledge of its development; if it was accepted by colleagues. PredAHT may therefore increase professionals’ confidence in their decision-making when investigating suspected AHT, but may be of less value in court

Qualitative analysis of clinician experience in utilising the BuRN Tool (Burns Risk assessment for Neglect or abuse Tool) in clinical practice

Introduction The BuRN-Tool (Burns Risk assessment for Neglect or abuse Tool) is a clinical prediction tool (CPT) aiding the identification of child maltreatment in children with burn injuries. The tool has been derived from systematic reviews and epidemiological studies, validated and is under-going an implementation evaluation. Clinician opinion on the use of this CPT is a key part of its evaluation. Objectives To explore the experience of emergency clinicians use of the BuRN-Tool in an emergency department (ED). Methods Three focus groups were conducted over a six-week period by the research team in the ED in the University Hospital of Wales; 25 emergency clinicians attended. A semi-structured approach was taken with pre-determined open-ended questions asked followed by a series of case vignettes to which the CPT was applied. The focus groups were recorded and transcribed verbatim. Thematic analysis was conducted for identification of pre-set and emergent themes. All data were double-coded. Results All participants said that it was acceptable to use the BuRN-Tool to aid in the decision-making process surrounding child maltreatment. All participants said that the BuRN-Tool was helpful and straight forward to use. All participants said that the tool was clinically beneficial, particularly for junior staff and those who do not always work in a paediatric environment. The clinical vignettes identified subjectivity in interpretation questions around adequate supervision, previous social care involvement and full thickness burns. This resulted in some variation in scoring. Conclusions This study confirms that the BuRN-Tool is acceptable in an ED setting. The focus groups demonstrated a homogenous and positive attitude regarding the layout, benefits and use of the BuRN-Tool. The subjective interpretation of some variables accounts for the non-uniformity in the scores generated. Clarification of questions will be made

Feasibility of Safe-Tea: A parent targeted intervention to prevent hot drink scalds in pre-school children

Objective Despite the high prevalence of preventable hot drink scalds in preschool children, there is a paucity of research on effective prevention interventions and a serious need to improve parents’ knowledge of first aid. This study investigates the feasibility of ‘Safe-Tea’, an innovative multifaceted community-based intervention delivered by early-years practitioners. Methods ‘Safe-Tea’ was implemented at Childcare, Stay&Play and Home Visit settings in areas of deprivation in Cardiff, UK. A mixed-methods approach was used, including preintervention and postintervention parent questionnaires and focus groups with parents and practitioners to test the acceptability, practicality and ability of staff to deliver the intervention, and parents’ knowledge and understanding. Results Intervention materials, activities and messages were well received and understood by both parents and community practitioners. Interactive and visual methods of communication requiring little to no reading were most acceptable. Parents’ understanding of the risk of hot drink scalds in preschool children and knowledge of appropriate first aid improved postintervention. Parents knew at baseline that they ‘should’ keep hot drinks out of reach. Focus group discussions after intervention revealed improved understanding of likelihood and severity of scald injury to children, which increased vigilance. Parents gained confidence to correct the behaviours of others at home and pass on first aid messages. Conclusion This feasibility study is a vital step towards the development of a robust, evidence-based behaviour change intervention model. Work is underway to refine intervention materials based on improvements suggested by parents, and test these more widely in communities across the UK

Factors influencing clinicians', health visitors' and social workers' professional judgements, decision‐making and multidisciplinary collaboration when safeguarding children with burn injuries: a qualitative study

Burns are a common injury to young children, sometimes related to neglect or physical abuse. Emergency department (ED) clinicians, health visitors and social workers must work collaboratively when safeguarding children with burns; however, little is known about the factors influencing their professional judgements, decision‐making and multidisciplinary collaboration. Objective was to explore factors affecting ED clinicians', health visitors' and social workers' professional judgements and decision‐making when children present to the ED with burns, and experiences of multidisciplinary collaboration, to identify areas for improvement. This was a qualitative semi‐structured interview study using purposive and snowball sampling to recruit participants. Data were analysed using ‘codebook’ thematic analysis. Four themes were identified: ‘perceived roles and responsibilities when safeguarding children with burn injuries’, ‘factors influencing judgment of risk and decision‐making’, ‘information sharing’ and ‘barriers and facilitators to successful multidisciplinary collaboration’. There is limited understanding between the groups about each other's roles. Each agency is dependent on one another to understand the full picture; however, information sharing is lacking in detail and context and hindered by organisational and resource constraints. Formal opportunities for multiagency team working such as strategy meetings can be facilitators of more successful collaborations. Professionals may benefit from multiagency training to improve understanding of one another's roles. Greater detail and context are needed when notifying health visitors of burn injuries in children or making a referral to children's services

Economic evaluation of an Australian nurse home visiting programme : a randomised trial at 3 years

Objectives To investigate the additional programme cost and cost-effectiveness of ‘right@home’ Nurse Home Visiting (NHV) programme in relation to improving maternal and child outcomes at child age 3 years compared with usual care. Design A cost–utility analysis from a government-as-payer perspective alongside a randomised trial of NHV over 3-year period. Costs and quality-adjusted lifeyears (QALYs) were discounted at 5%. Analysis used an intention-to-treat approach with multiple imputation. Setting The right@home was implemented from 2013 in Victoria and Tasmania states of Australia, as a primary care service for pregnant women, delivered until child age 2 years. Participants 722 pregnant Australian women experiencing adversity received NHV (n=363) or usual care (clinic visits) (n=359). Primary and secondary outcome measures First, a cost–consequences analysis to compare the additional costs of NHV over usual care, accounting for any reduced costs of service use, and impacts on all maternal and child outcomes assessed at 3 years. Second, cost–utility analysis from a government-as-payer perspective compared additional costs to maternal QALYs to express cost-effectiveness in terms of additional cost per additional QALY gained. Results When compared with usual care at child age 3 years, the right@home intervention cost $A7685 extra per woman (95$A7006 to $A8364) and generated 0.01 more QALYs (95$A50 000 per QALY. Conclusions Benefits of NHV to parenting at 2 years and maternal health and well-being at 3 years translate into marginal maternal QALY gains. Like previous cost-effectiveness results for NHV programmes, right@home is not cost-effective at 3 years. Given the relatively high up-front costs of NHV, long-term follow-up is needed to assess the accrual of health and economic benefits over time
