Mental health and other factors associated with work productivity after injury in the UK: multicentre cohort study.

INTRODUCTION: Mental health conditions are a major contributor to productivity loss and are common after injury. This study quantifies postinjury productivity loss and its association with preinjury and postinjury mental health, injury, demographic, health, social and other factors. METHODS: Multicentre, longitudinal study recruiting hospitalised employed individuals aged 16-69 years with unintentional injuries, followed up at 1, 2, 4 and 12 months. Participants completed questionnaires on injury, demographic factors, health (including mental health), social factors, other factors and on-the-job productivity upon return to work (RTW). ORs were estimated for above median productivity loss using random effects logistic regression. RESULTS: 217 adults had made an RTW at 2, 4 or 12 months after injury: 29% at 2 months, 66% at 4 months and 83% at 12 months. Productivity loss reduced over time: 3.3% of working time at 2 months, 1.7% at 4 months, 1% at 12 months. Significantly higher productivity loss was associated with preinjury psychiatric conditions (OR 21.40, 95% CI 3.50 to 130.78) and post-traumatic stress avoidance symptoms at 1 month (OR for 1-unit increase in score 1.15, 95% CI 1.07 to 1.22). Significantly lower productivity loss was associated with male gender (OR 0.32, 95% CI 0.14 to 0.74), upper and lower limb injuries (vs other body regions, OR 0.15, 95% CI 0.03 to 0.81) and sports injuries (vs home, OR 0.18, 95% CI 0.04 to 0.78). Preinjury psychiatric conditions and gender remained significant in analysis of multiply imputed data. CONCLUSIONS: Unintentional injury results in substantial productivity loss. Females, those with preinjury psychiatric conditions and those with post-traumatic stress avoidance symptoms experience greater productivity loss and may require additional support to enable successful RTW.

The COVID-19 Clinician Cohort (CoCCo) Study: Empirically Grounded Recommendations for Forward-Facing Psychological Care of Frontline Doctors.

This study aimed to develop empirically grounded recommendations and a coherent model of psychological care derived from the experiences and psychological care needs of COVID-19 frontline doctors, using semi-structured interviews and thematic analysis. Participants were UK frontline doctors specialising in Emergency Medicine, Anaesthetics, or Intensive Care (n = 31) purposively sampled for maximum variation on gender, specialty, ethnicity, and trauma-related distress; most worked in ICU during the pandemic (71%). Four themes were derived: (1) 'coping strategies', participants used many, including exercise, mindfulness, and "wait until it gets really bad"; (2) 'sources of support', participants valued embedded psychological support, digital services, and informal conversations with colleagues or family, though there was little opportunity; (3) 'organisational influences on wellbeing', participants reported a love-hate relationship for concepts like 'wellbeing', seen as important but insulting when basic workplace needs were unmet; (4) 'improving engagement with support', analysis suggests we must reduce physical and psychological barriers to access and encourage leaders to model psychologically supportive behaviours. Doctors' frontline COVID-19 working experiences shine a 'spotlight' on pre-existing problems such as lack of physical resources and access to psychological care. Empirically grounded recommendations and a model of incremental psychological care are presented for use in clinical services.

Embracing complexity and uncertainty to create impact: exploring the processes and transformative potential of co-produced research through development of a social impact model.

The potential use, influence and impact of health research is seldom fully realised. This stubborn problem has caused burgeoning global interest in research aiming to address the implementation 'gap' and factors inhibiting the uptake of scientific evidence. Scholars and practitioners have questioned the nature of evidence used and required for healthcare, highlighting the complex ways in which knowledge is formed, shared and modified in practice and policy. This has led to rapid expansion, expertise and innovation in the field of knowledge mobilisation and funding for experimentation into the effectiveness of different knowledge mobilisation models. One approach gaining prominence involves stakeholders (e.g. researchers, practitioners, service users, policy-makers, managers and carers) in the co-production, and application, of knowledge for practice, policy and research (frequently termed integrated knowledge translation in Canada). Its popularity stems largely from its potential to address dilemmas inherent in the implementation of knowledge generated using more reductionist methods. However, despite increasing recognition, demands for co-produced research to illustrate its worth are becoming pressing while the means to do so remain challenging. This is due not only to the diversity of approaches to co-production and their application, but also to the ways through which different stakeholders conceptualise, measure, reward and use research. While research co-production can lead to demonstrable benefits such as policy or practice change, it may also have more diffuse and subtle impact on relationships, knowledge sharing, and in engendering culture shifts and research capacity-building. These relatively intangible outcomes are harder to measure and require new emphases and tools. This opinion paper uses six Canadian and United Kingdom case studies to explore the principles and practice of co-production and illustrate how it can influence interactions between research, policy and practice, and benefit diverse stakeholders. In doing so, we identify a continuum of co-production processes. We propose and illustrate the use of a new 'social model of impact' and framework to capture multi-layered and potentially transformative impacts of co-produced research. We make recommendations for future directions in research co-production and impact measurement.

Psychological morbidity and return to work after injury: multicentre cohort study.

BACKGROUND: The benefits of work for physical, psychological, and financial wellbeing are well documented. Return to work (RTW) after unintentional injury is often delayed, and psychological morbidity may contribute to this delay. The impact of psychological morbidity on RTW after a wide range of unintentional injuries in the UK has not been adequately quantified. AIM: To quantify the role of psychological factors, including anxiety, depression, and post-traumatic distress, on RTW following unintentional injuries. DESIGN AND SETTING: A longitudinal multicentre prospective study was undertaken in Nottingham, Bristol, Leicester, and Guildford, UK. METHOD: Participants (n = 273) were 16-69-year-olds admitted to hospital following unintentional injury, who were in paid employment prior to injury. They were surveyed at baseline, then at 1, 2, 4, and 12 months following injury; demographic data were collected along with injury characteristics, psychological morbidity, and RTW status. Associations between demographic, injury and psychological factors, and RTW between 2 and 12 months after injury were quantified using random effects logistic regression. RESULTS: The odds of RTW between 2 and 12 months after injury reduced as depression scores early in the recovery period (1 month after injury) increased (odds ratio [OR] 0.87, 95% confidence interval [CI] = 0.79 to 0.95) and as length of hospital stay increased (OR 0.91, 95% CI] = 0.86 to 0.96). For those experiencing threatening life events following injury (OR 0.27, 95% CI = 0.10 to 0.72) and with higher scores on the Crisis Support Scale (OR 0.93, 95% CI] = 0.88 to 0.99), the odds of RTW between 2 and 12 months after injury were lower. Multiple imputation analysis found similar results, but those relating to crisis support did not remain statistically significant. CONCLUSION: Primary care professionals can identify patients at risk of delayed RTW who may benefit from management of psychological morbidity and support to RTW.

Evaluating implementation of a fire-prevention injury prevention briefing in children's centres: Cluster randomised controlled trial.

BACKGROUND: Many developed countries have high mortality rates for fire-related deaths in children aged 0-14 years with steep social gradients. Evidence-based interventions to promote fire safety practices exist, but the impact of implementing a range of these interventions in children's services has not been assessed. We developed an Injury Prevention Briefing (IPB), which brought together evidence about effective fire safety interventions and good practice in delivering interventions; plus training and facilitation to support its use and evaluated its implementation. METHODS: We conducted a cluster randomised controlled trial, with integrated qualitative and cost-effectiveness nested studies, across four study sites in England involving children's centres in disadvantaged areas; participants were staff and families attending those centres. Centres were stratified by study site and randomised within strata to one of three arms: IPB plus facilitation (IPB+), IPB only, usual care. IPB+ centres received initial training and facilitation at months 1, 3, and 8. Baseline data from children's centres were collected between August 2011 and January 2012 and follow-up data were collected between June 2012 and June 2013. Parent baseline data were collected between January 2012 and May 2012 and follow-up data between May 2013 and September 2013. Data comprised baseline and 12 month parent- and staff-completed questionnaires, facilitation contact data, activity logs and staff interviews. The primary outcome was whether families had a plan for escaping from a house fire. Treatment arms were compared using multilevel models to account for clustering by children's centre. RESULTS: 1112 parents at 36 children's centres participated. There was no significant effect of the intervention on families' possession of plans for escaping from a house fire (adjusted odds ratio (AOR) IPB only vs. usual care: 0.93, 95%CI 0.58, 1.49; AOR IPB+ vs. usual care 1.41, 95%CI 0.91, 2.20). However, significantly more families in the intervention arms reported more behaviours for escaping from house fires (AOR IPB only vs. usual care: 2.56, 95%CI 01.38, 4.76; AOR IPB+ vs. usual care 1.78, 95%CI 1.01, 3.15). CONCLUSION: Our study demonstrated that children's centres can deliver an injury prevention intervention to families in disadvantaged communities and achieve changes in home safety behaviours.

A mixed-method study of pain management practice in a UK children's hospital: identification of barriers and developing strategies to maintain effective in-patient paediatric pain management.

AIM: To assess Acute Pain Service and paediatric pain management efficacy in a UK specialist paediatric hospital to inform wider recommendations for future sustainability. BACKGROUND: UK paediatric acute pain services vary. Although comprehensive pain management guidelines exist, consensus on the best model of care is lacking. Worldwide, medical and pharmacological advances and rapid patient turnover have increased the challenges of managing hospitalized children's pain. Simultaneously nurses, who deliver the bulk of pain management, have experienced reduction in skill mix and training opportunities. Specialist Acute Pain Services have evolved to meet these demands; their overall efficacy is unknown. DESIGN: This mixed-methods study explores pain management practice at a UK paediatric hospital to assess current efficacy and future sustainability. METHOD: A 2013 case note review of all Acute Pain Services referrals over 14 days were compared with an interval sample of concurrent non-referred inpatient children; seven semi-structured interviews were conducted with a range of clinical staff. RESULTS: Twenty-two referrals of 15 children were made; 15 comparison children were identified. All 30 children (100%) were appropriately referred/non-referred. Acute Pain Services cases experienced higher pain levels, were more likely to have long term conditions, longer hospital stay and repeat admissions. Three key themes emerged through interview analysis: 'addressing pain', 'changing contexts' 'pain as an "expert" skill'. Increased specialization, reduced clarity between different pain modalities and decreased training opportunities had resulted in potentially unsustainable APS dependence.

Seeking support after hospitalisation for injury: a nested qualitative study of the role of primary care.

BACKGROUND: In the UK, studies suggest that the transition from hospital to home after an injury can be a difficult time and many patients report feeling inadequately prepared. Patients often use primary care services after hospital discharge. These consultations provide opportunities to consider problems that patients experience and to facilitate recovery. Little is known, however, about how patients and service providers view care after hospital discharge and the role played by primary care services, specifically GPs. AIM: To identify good practice and unmet needs in respect of post-discharge support for injured patients. DESIGN AND SETTING: Qualitative study using semi-structured interviews at four sites (Bristol, Leicester/Loughborough, Nottingham, and Surrey). METHOD: Qualitative interviews with 40 service providers and 45 hospitalised injured patients. RESULTS: Although there were examples of well-managed hospital discharges, many patients felt they were not provided with the information they needed about their injury, what to expect in terms of recovery, pain control, return to work, psychological problems, and services to help meet their needs. They also described difficulty accessing services such as physiotherapy or counselling. Service providers identified problems with communication between secondary and primary care, lack of access to physiotherapy, poor communication about other services that may help patients, GP service and resource constraints, and difficulties in providing information to patients concerning likely prognosis. CONCLUSION: Discharge from hospital after an injury can be problematic for patients. Changes in both secondary and primary care are required to resolve this problem.

Understanding and meeting information needs following unintentional injury: comparing the accounts of patients, carers and service providers.

OBJECTIVE: To explore information needs of unintentional injury patients and their carers over time, across services, and how such needs are met from the perspectives of patients, carers and service providers. METHODS: Qualitative nested study within a multi-centre longitudinal study quantifying psycho-social, physical, occupational outcomes and service use and costs following a range of unintentional injuries. Semi-structured interviews conducted with 45 patients during the first year post injury, 18 of their carers and 40 providers of services. RESULTS: Patients and carers needed information about the nature and severity of injury, prognosis, self-management and further services. Information needs changed over time with the biggest difficulties being during transfer from primary to secondary care. Barriers to information provision included service providers' time limitations and uncertainty around information provision, and patients' reluctance to ask for information or inability to process it. Suggested improvements included provision of reassurance as well as factual information, information about further services, earlier follow-up, increased appointment times and greater involvement of families where appropriate. CONCLUSIONS: The information needs of patients and carers post injury change with time and there are a number of ways to remove gaps and barriers in current provision to meet such needs. PRACTICE IMPLICATIONS: Providing information on injury management, prognosis and available services and reassurance at each stage of the recovery process in secondary care and when transferring to primary care would be helpful for patients and carers. A follow-up contact soon after discharge and the opportunity to ask questions could be beneficial. Better information about the patient's needs and ways they can help could help carers fulfil their caring role.

Implementing an Injury Prevention Briefing to aid delivery of key fire safety messages in UK children's centres: qualitative study nested within a multi-centre randomised controlled trial.

BACKGROUND: To improve the translation of public health evidence into practice, there is a need to increase practitioner involvement in initiative development, to place greater emphasis on contextual knowledge, and to address intervention processes and outcomes. Evidence that demonstrates the need to reduce childhood fire-related injuries is compelling but its translation into practice is inconsistent and limited. With this knowledge the Keeping Children Safe programme developed an "Injury Prevention Briefing (IPB)" using a 7 step process to combine scientific evidence with practitioner contextual knowledge. The IPB was designed specifically for children's centres (CCs) to support delivery of key fire safety messages to parents. This paper reports the findings of a nested qualitative study within a clustered randomised controlled trial of the IPB, in which staff described their experiences of IPB implementation to aid understanding of why or how the intervention worked. METHODS: Interviews were conducted with key staff at 24 CCs participating in the two intervention arms: 1) IPB supplemented by initial training and regular facilitation; 2) IPB sent by post with no facilitation. Framework Analysis was applied to these interview data to explore intervention adherence including; exposure or dose; quality of delivery; participant responsiveness; programme differentiation; and staff experience of IPB implementation. This included barriers, facilitators and suggested improvements. RESULTS: 83% of CCs regarded the IPB as a simple, accessible tool which raised awareness, and stimulated discussion and behaviour change. 15 CCs suggested minor modifications to format and content. Four levels of implementation were identified according to content, frequency, duration and coverage. Most CCs (75%) achieved 'extended' or 'essential' IPB implementation. Three universal factors affected all CCs: organisational change and resourcing; working with hard to engage groups; additional demands of participating in a research study. Six specific factors were associated with the implementation level achieved: staff engagement and training; staff continuity; adaptability and flexibility; other agency support; conflicting priorities; facilitation. CCs achieving high implementation levels increased from 58% (no facilitation) to 92% with facilitation. CONCLUSION: Incorporating service provider perspectives and scientific evidence into health education initiatives enhances potential for successful implementation, particularly when supplemented by ongoing training and facilitation.

Providing effective trauma care: the potential for service provider views to enhance the quality of care (qualitative study nested within a multicentre longitudinal quantitative study).

OBJECTIVE: To explore views of service providers caring for injured people on: the extent to which services meet patients' needs and their perspectives on factors contributing to any identified gaps in service provision. DESIGN: Qualitative study nested within a quantitative multicentre longitudinal study assessing longer term impact of unintentional injuries in working age adults. Sampling frame for service providers was based on patient-reported service use in the quantitative study, patient interviews and advice of previously injured lay research advisers. Service providers' views were elicited through semistructured interviews. Data were analysed using thematic analysis. SETTING: Participants were recruited from a range of settings and services in acute hospital trusts in four study centres (Bristol, Leicester, Nottingham and Surrey) and surrounding areas. PARTICIPANTS: 40 service providers from a range of disciplines. RESULTS: Service providers described two distinct models of trauma care: an 'ideal' model, informed by professional knowledge of the impact of injury and awareness of best models of care, and a 'real' model based on the realities of National Health Service (NHS) practice. Participants' 'ideal' model was consistent with standards of high-quality effective trauma care and while there were examples of services meeting the ideal model, 'real' care could also be fragmented and inequitable with major gaps in provision. Service provider accounts provide evidence of comprehensive understanding of patients' needs, awareness of best practice, compassion and research but reveal significant organisational and resource barriers limiting implementation of knowledge in practice. CONCLUSIONS: Service providers envisage an 'ideal' model of trauma care which is timely, equitable, effective and holistic, but this can differ from the care currently provided. Their experiences provide many suggestions for service improvements to bridge the gap between 'real' and 'ideal' care. Using service provider views to inform service design and delivery could enhance the quality, patient experience and outcomes of care.

Professional wellbeing and caring: exploring a complex relationship.

There is growing concern about lack of compassion in nursing. Impact of Injuries, which is the parent study (Kendrick et al, 2011) of this independent nested study, collected patient accounts of care received by physiotherapists and nurses. While physiotherapists were generally described as caring, nursing care was less consistent and sometimes uncaring. This embedded study conducted semi-structured interviews in 2012 with 11 physiotherapists and 12 nurses in four English hospitals to obtain perspectives on the provision of care. Physiotherapists presented a distinct identity with caring both integral to the role and sustained by structural and organisational factors. Nurses had a diffuse identity with limited control within a medical and business model of care. They appeared 'under siege' and were nostalgic for caring, which was frequently subordinate to other demands. Both nurses and physiotherapists faced challenges but nurses felt the context of their work was not conducive to caring. This article draws comparisons between these professions and makes informed recommendations to improve nursing practice and patient care.

The mechanical environment in Dupuytren's contracture determines cell contractility and associated MMP-mediated matrix remodeling.

Matrix metalloproteinases (MMPs) are expressed in Dupuytren's contracture and play a role in matrix remodeling. We tested the role of tension on contractility and MMP expression in Dupuytren's nodule and cord cells. Cells were subjected to pre-determined loading patterns of known repeatable magnitudes (static load, unloading, and overloading) and tested for MMP gene expression (MMP-1, -2, -9, -13, and TIMP-1, -2) and force generation using a tension-culture force monitor. Matrix remodeling was assessed by addition of cytochalasin D and residual matrix tension was quantified. Nodule compared to cord and control cells demonstrate greater force generation and remodeling (p < 0.05). Nodule cells subjected to a reduced load and overloading led to threefold increase of MMP-1, -2, and -9 compared to static load, whilst cord and control cells only showed a twofold increase of MMP-9. Nodule cells subjected to overloading showed a twofold increase in TIMP-2 expression, whilst cord and control cells showed a twofold increase in TIMP-1 expression. Nodule cells differ from cord cells by increased force generation in response to changes in the mechanical environment and related MMP/TIMP-mediated matrix remodeling. In turn this may lead to permanent matrix shortening and digital contracture. Interventional therapies should be aimed at nodule cells to prevent contraction and subsequent permanent matrix remodeling.

Transforming growth factor-beta1 stimulation enhances Dupuytren's fibroblast contraction in response to uniaxial mechanical load within a 3-dimensional collagen gel.

PURPOSE: A function of fibroblasts is the generation of cytomechanical force within their surrounding extracellular matrix. Abnormalities in force generation may be the cause of many pathologic conditions including scarring, and some fibroproliferative disorders such as Dupuytren's disease, which is the focus of this report. METHODS: This work investigated the cytomechanical responses of Dupuytren's-derived fibroblasts to externally applied mechanical force using a culture force monitor model, with and without stimulation with the fibrosis-linked cytokine, transforming growth factor-beta1 (TGF-beta1). We compared these responses with cytomechanical responses of fibroblasts derived from the transverse carpal ligament. RESULTS: Dupuytren's fibroblasts display a significantly greater ability to contract a collagen matrix compared with control fibroblasts, with a maximum generated force of 131 dynes (p < .001). These cells did not exhibit a characteristic plateau phase in the contraction, which indicates a delay in achieving tensional homeostasis from Dupuytren's-derived cells. After being subjected to uniaxial overload and underload, Dupuytren's fibroblasts responded by increased force generation, whereas control fibroblasts responded by a reduction in force in response to an overload, and contraction in response to an underload. These changes were exacerbated by the addition of the profibrotic factor TGF-beta1, with a significant increase in generated force for all cell types, in particular during the early phase of fibroblast attachment and contraction, and a positive contraction gradient in response to overloading forces. CONCLUSIONS: These data suggest that cells derived from this fibrotic disease display characteristic abnormalities in force generation profiles. Their default response to loading or underloading is contraction, or increased force generation. This work highlights the role of TGF-beta1 as a mechano-transduction cytokine, which has an influence on the early phase cell of force generation, as well as a role in mechanical responses of cells to external mechanical stimuli. This, in turn, may influence the progression of Dupuytren's disease and the high rates of recurrence seen postoperatively.
