ABSTRACT

OBJECTIVE: The aim of the Ankle Fracture Treatment: Enhancing Rehabilitation (AFTER) study, a multicentre external pilot parallel-group randomised controlled trial (RCT), was to assess feasibility of a definitive trial comparing rehabilitation approaches after ankle fracture. SETTING: Five UK National Health Service hospitals. PARTICIPANTS: Participants were aged 50 years and over with an ankle fracture requiring immobilisation for at least 4 weeks. INTERVENTIONS: Participants were allocated 1:1 via a central web-based randomisation system to: (1) best practice advice (one session of physiotherapy, up to two optional additional advice sessions) or (2) progressive exercise (up to six sessions of physiotherapy). PRIMARY OUTCOME MEASURES: Feasibility: (1) participation rate, (2) intervention adherence and (3) retention. RESULTS: Sixty-one of 112 (54%) eligible participants participated, exceeding progression criteria for participation of 25%. Recruitment progression criteria was 1.5 participants per site per month and 1.4 was observed. At least one intervention session was delivered for 28/30 (93%) of best practice advice and 28/31 (90%) of progressive exercise participants, exceeding the 85% progression criteria. For those providing follow-up data, the proportion of participants reporting performance of home exercises in the best practice advice and the progressive exercise groups at 3 months was 20/23 (87%) and 21/25 (84%), respectively. Mean time from injury to starting physiotherapy was 74.1 days (95% CI 53.9 to 94.1 days) for the best practice advice and 72.7 days (95% CI 54.7 to 88.9) for the progressive exercise group. Follow-up rate (6-month Olerud and Molander Ankle Score) was 28/30 (93%) for the best practice advice group and 26/31 (84%) in the progressive exercise group with an overall follow-up rate of 89%. CONCLUSIONS: This pilot RCT demonstrated that a definitive trial would be feasible. The main issues to address for a definitive trial are intervention modifications to enable earlier provision of rehabilitation and ensuring similar rates of follow-up in each group. TRIAL REGISTRATION NUMBER: ISRCTN16612336.

ABSTRACT

AIMS: To determine whether platelet-rich plasma (PRP) injection improves outcomes two years after acute Achilles tendon rupture. METHODS: A randomized multicentre two-arm parallel-group, participant- and assessor-blinded superiority trial was undertaken. Recruitment commenced on 28 July 2015 and two-year follow-up was completed in 21 October 2019. Participants were 230 adults aged 18 years and over, with acute Achilles tendon rupture managed with non-surgical treatment from 19 UK hospitals. Exclusions were insertion or musculotendinous junction injuries, major leg injury or deformity, diabetes, platelet or haematological disorder, medication with systemic corticosteroids, anticoagulation therapy treatment, and other contraindicating conditions. Participants were randomized via a central online system 1:1 to PRP or placebo injection. The main outcome measure was Achilles Tendon Rupture Score (ATRS) at two years via postal questionnaire. Other outcomes were pain, recovery goal attainment, and quality of life. Analysis was by intention-to-treat. RESULTS: A total of 230 participants were randomized, 114 to PRP and 116 to placebo. Two-year questionnaires were sent to 216 participants who completed a six-month questionnaire. Overall, 182/216 participants (84%) completed the two-year questionnaire. Participants were aged a mean of 46 years (SD 13.0) and 25% were female (57/230). The majority of participants received the allocated intervention (219/229, 96%). Mean ATRS scores at two years were 82.2 (SD 18.3) in the PRP group (n = 85) and 83.8 (SD 16.0) in the placebo group (n = 92). There was no evidence of a difference in the ATRS at two years (adjusted mean difference -0.752, 95% confidence interval -5.523 to 4.020; p = 0.757) or in other secondary outcomes, and there were no re-ruptures between 24 weeks and two years. CONCLUSION: PRP injection did not improve patient-reported function or quality of life two years after acute Achilles tendon rupture compared with placebo. The evidence from this study indicates that PRP offers no patient benefit in the longer term for patients with acute Achilles tendon rupture.Cite this article: Bone Joint J 2022;104-B(11):1256-1265.

ABSTRACT

AIMS: The rationale for exacting restoration of skeletal anatomy after unstable ankle fracture is to improve outcomes by reducing complications from malunion; however, current definitions of malunion lack confirmatory clinical evidence. METHODS: Radiological (absolute radiological measurements aided by computer software) and clinical (clinical interpretation of radiographs) definitions of malunion were compared within the Ankle Injury Management (AIM) trial cohort, including people aged ≥ 60 years with an unstable ankle fracture. Linear regressions were used to explore the relationship between radiological malunion (RM) at six months and changes in function at three years. Function was assessed with the Olerud-Molander Ankle Score (OMAS), with a minimal clinically important difference set as six points, as per the AIM trial. Piecewise linear models were used to investigate new radiological thresholds which better explain symptom impact on ankle function. RESULTS: Previously described measures of RM and surgeon opinion of clinically significant malunion (CSM) were shown to be related but with important differences. CSM was more strongly related to outcome (-13.9 points on the OMAS; 95% confidence interval (CI) -21.9 to -5.4) than RM (-5.5 points; 95% CI -9.8 to -1.2). Existing malunion thresholds for talar tilt and tibiofibular clear space were shown to be slightly conservative; new thresholds which better explain function were identified (talar tilt > 2.4°; tibiofibular clear space > 6 mm). Based on this new definition the presence of RM had an impact on function, which was statistically significant, but the clinical significance was uncertain (-9.1 points; 95% CI -13.8 to -4.4). In subsequent analysis, RM of a posterior malleolar fracture was shown to have a statistically significant impact on OMAS change scores, but the clinical significance was uncertain (-11.6 points; 95% CI -21.9 to -0.6). CONCLUSION: These results provide clinical evidence which supports the previously accepted definitions. Further research to investigate more conservative clinical thresholds for malunion is indicated.Cite this article: Bone Jt Open 2022;3(10):841-849.

ABSTRACT

BACKGROUND: Falls and fractures are a major problem. OBJECTIVES: To investigate the clinical effectiveness and cost-effectiveness of alternative falls prevention interventions. DESIGN: Three-arm, pragmatic, cluster randomised controlled trial with parallel economic analysis. The unit of randomisation was the general practice. SETTING: Primary care. PARTICIPANTS: People aged ≥ 70 years. INTERVENTIONS: All practices posted an advice leaflet to each participant. Practices randomised to active intervention arms (exercise and multifactorial falls prevention) screened participants for falls risk using a postal questionnaire. Active treatments were delivered to participants at higher risk of falling. MAIN OUTCOME MEASURES: The primary outcome was fracture rate over 18 months, captured from Hospital Episode Statistics, general practice records and self-report. Secondary outcomes were falls rate, health-related quality of life, mortality, frailty and health service resource use. Economic evaluation was expressed in terms of incremental cost per quality-adjusted life-year and incremental net monetary benefit. RESULTS: Between 2011 and 2014, we randomised 63 general practices (9803 participants): 21 practices (3223 participants) to advice only, 21 practices (3279 participants) to exercise and 21 practices (3301 participants) to multifactorial falls prevention. In the active intervention arms, 5779 out of 6580 (87.8%) participants responded to the postal fall risk screener, of whom 2153 (37.3%) were classed as being at higher risk of falling and invited for treatment. The rate of intervention uptake was 65% (697 out of 1079) in the exercise arm and 71% (762 out of 1074) in the multifactorial falls prevention arm. Overall, 379 out of 9803 (3.9%) participants sustained a fracture. There was no difference in the fracture rate between the advice and exercise arms (rate ratio 1.20, 95% confidence interval 0.91 to 1.59) or between the advice and multifactorial falls prevention arms (rate ratio 1.30, 95% confidence interval 0.99 to 1.71). There was no difference in falls rate over 18 months (exercise arm: rate ratio 0.99, 95% confidence interval 0.86 to 1.14; multifactorial falls prevention arm: rate ratio 1.13, 95% confidence interval 0.98 to 1.30). A lower rate of falls was observed in the exercise arm at 8 months (rate ratio 0.78, 95% confidence interval 0.64 to 0.96), but not at other time points. There were 289 (2.9%) deaths, with no differences by treatment arm. There was no evidence of effects in prespecified subgroup comparisons, nor in nested intention-to-treat analyses that considered only those at higher risk of falling. Exercise provided the highest expected quality-adjusted life-years (1.120), followed by advice and multifactorial falls prevention, with 1.106 and 1.114 quality-adjusted life-years, respectively. NHS costs associated with exercise (£3720) were lower than the costs of advice (£3737) or of multifactorial falls prevention (£3941). Although incremental differences between treatment arms were small, exercise dominated advice, which in turn dominated multifactorial falls prevention. The incremental net monetary benefit of exercise relative to treatment valued at £30,000 per quality-adjusted life-year is modest, at £191, and for multifactorial falls prevention is £613. Exercise is the most cost-effective treatment. No serious adverse events were reported. LIMITATIONS: The rate of fractures was lower than anticipated. CONCLUSIONS: Screen-and-treat falls prevention strategies in primary care did not reduce fractures. Exercise resulted in a short-term reduction in falls and was cost-effective. FUTURE WORK: Exercise is the most promising intervention for primary care. Work is needed to ensure adequate uptake and sustained effects. TRIAL REGISTRATION: Current Controlled Trials ISRCTN71002650. FUNDING: This project was funded by the National Institute for Health Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 25, No. 34. See the NIHR Journals Library website for further project information.


WHAT IS THE PROBLEM?: Falls are a major problem for older people. Current practice is to give people advice leaflets. Another approach is exercise, especially balance and strength training. A third alternative is to invite older people to attend a falls assessment with a health-care professional, either a doctor or a trained nurse. This usually involves a careful check of prescribed tablets, blood pressure, eyesight and other problems that might cause falls. WHAT DID WE DO?: We compared three strategies. We recruited 9803 people aged 70­101 years from 63 general practices across England. We randomly allocated practices in clusters into three treatment groups. The participants in one group were given a Staying Steady advice leaflet (Age UK. Staying Steady. London: Age UK; 2009). Participants in the second group received the same leaflet and were assessed to see if they were at higher risk of falling. Those participants identified as being at higher risk (about 1000 people) were invited to take part in an exercise programme, supported by an exercise therapist. These people did balance and strength training at home for up to 6 months. In the third group, we again identified participants who were at higher risk of falling (about 1000 people) and invited them for a detailed falls assessment with a trained nurse or doctor. This last group of participants were referred for other treatments if any health problems were found. In all groups we counted fractures and falls and measured changes in quality of life, frailty and the cost of the treatments over 18 months of follow-up. WHAT DID WE FIND OUT?: We found no difference in the number of fractures over 18 months between the different treatments. The exercise programme reduced falls in the short term but not over the longer term. The exercise programme was cheaper and led to a slightly better overall quality of life.

ABSTRACT

OBJECTIVES: The time taken for older people to recover from hip fracture can be extensive. The aim of this study was to gain an understanding of patient and informal carer experience of recovery in the early stage, while in acute care. DESIGN: A phenomenological (lived experience) approach was used to guide the design of the study. Interviews and observation took place between March 2016 and December 2016 in acute care. SETTING: Trauma wards in a National Health Service Foundation Trust in the South West of England. PARTICIPANTS: A purposive sample of 25 patients were interviewed and observation taking 52 hours was undertaken with 13 patients and 12 staff. 11 patients had memory loss, 2 patients chose to take part in an interview and observation. The age range was 63-91 years (median 83), 10 were men. A purposive sample of 25 informal carers were also interviewed, the age range was 42-95 years (mean 64), 11 were men. RESULTS: The results identified how participants moved forward together after injury by sharing the journey. This was conveyed through three themes: (1) sustaining relationships while experiencing strong emotions and actively helping, (2) becoming aware of uncertainty about the future and working through possible outcomes, (3) being changed, visibly looking different, not being able to walk, and enduring indignity and pain. CONCLUSION: This study identified the experience of patients and informal carers as they shared the journey during a challenging life transition. Strategies that support well-being and enable successful negotiation of the emotional and practical challenges of acute care may help with longer term recovery. Research should focus on developing interventions that promote well-being during this transition to help provide the foundation for patients and carers to live fulfilled lives.

ABSTRACT

Platelet-rich plasma (PRP) is an autologous preparation that has been claimed to improve healing and mechanobiological properties of tendons both in vitro and in vivo. In this sub-study from the PATH-2 (PRP in Achilles Tendon Healing-2) trial, we report the cellular and growth factor content and quality of the Leukocyte-rich PRP (L-PRP) (N = 103) prepared using a standardized commercial preparation method across 19 different UK centers. Baseline whole blood cell counts (red cells, leukocyte and platelets) demonstrated that the two groups were well-matched. L-PRP analysis gave a mean platelet count of 852.6 x 109/L (SD 438.96), a mean leukocyte cell count of 15.13 x 109/L (SD 10.28) and a mean red blood cell count of 0.91 x 1012/L (SD 1.49). The activation status of the L-PRP gave either low or high expression levels of the degranulation marker CD62p before and after ex-vivo platelet activation respectively. TGF-ß, VEGF, PDGF, IGF and FGFb mean concentrations were 131.92 ng/ml, 0.98 ng/ml, 55.34 ng/ml, 78.2 ng/ml and 111.0 pg/ml respectively with expected correlations with both platelet and leukocyte counts. While PATH-2 results demonstrated that there was no evidence L-PRP is effective for improving clinical outcomes at 24 weeks after Achilles tendon rupture, our findings support that the majority of L-PRP properties were within the method specification and performance.

ABSTRACT

BACKGROUND: Community screening and therapeutic prevention strategies may reduce the incidence of falls in older people. The effects of these measures on the incidence of fractures, the use of health resources, and health-related quality of life are unknown. METHODS: In a pragmatic, three-group, cluster-randomized, controlled trial, we estimated the effect of advice sent by mail, risk screening for falls, and targeted interventions (multifactorial fall prevention or exercise for people at increased risk for falls) as compared with advice by mail only. The primary outcome was the rate of fractures per 100 person-years over 18 months. Secondary outcomes were falls, health-related quality of life, frailty, and a parallel economic evaluation. RESULTS: We randomly selected 9803 persons 70 years of age or older from 63 general practices across England: 3223 were assigned to advice by mail alone, 3279 to falls-risk screening and targeted exercise in addition to advice by mail, and 3301 to falls-risk screening and targeted multifactorial fall prevention in addition to advice by mail. A falls-risk screening questionnaire was sent to persons assigned to the exercise and multifactorial fall-prevention groups. Completed screening questionnaires were returned by 2925 of the 3279 participants (89%) in the exercise group and by 2854 of the 3301 participants (87%) in the multifactorial fall-prevention group. Of the 5779 participants from both these groups who returned questionnaires, 2153 (37%) were considered to be at increased risk for falls and were invited to receive the intervention. Fracture data were available for 9802 of the 9803 participants. Screening and targeted intervention did not result in lower fracture rates; the rate ratio for fracture with exercise as compared with advice by mail was 1.20 (95% confidence interval [CI], 0.91 to 1.59), and the rate ratio with multifactorial fall prevention as compared with advice by mail was 1.30 (95% CI, 0.99 to 1.71). The exercise strategy was associated with small gains in health-related quality of life and the lowest overall costs. There were three adverse events (one episode of angina, one fall during a multifactorial fall-prevention assessment, and one hip fracture) during the trial period. CONCLUSIONS: Advice by mail, screening for fall risk, and a targeted exercise or multifactorial intervention to prevent falls did not result in fewer fractures than advice by mail alone.

ABSTRACT

BACKGROUND: The utilization of helicopter emergency medical services (HEMS) in modern trauma systems has been a source of debate for many years. This study set to establish the true impact of HEMS in England on survival for patients with major trauma. METHODS: A comparative cohort design using prospectively recorded data from the UK Trauma Audit and Research Network registry. 279 107 patients were identified between January 2012 and March 2017. The primary outcome measure was risk adjusted in-hospital mortality within propensity score matched cohorts using logistic regression analysis. Subset analyses were performed for subjects with prehospital Glasgow Coma Scale <8, respiratory rate <10 or >29 and systolic blood pressure <90. RESULTS: The analysis was based on 61 733 adult patients directly admitted to major trauma centers: 54 185 ground emergency medical services (GEMS) and 7548 HEMS. HEMS patients were more likely male, younger, more severely injured, more likely to be victims of road traffic collisions and intubated at scene. Crude mortality was higher for HEMS patients. Logistic regression demonstrated a 15% reduction in the risk adjusted odds of death (OR=0.846; 95% CI 0.684 to 1.046) in favor of HEMS. When analyzed for patients previously noted to benefit most from HEMS, the odds of death were reduced further but remained statistically consistent with no effect. Sensitivity analysis on 5685 patients attended by a doctor on scene but transported by GEMS demonstrated a protective effect on mortality versus the standard GEMS response (OR 0.77; 95% CI 0.62 to 0.95). DISCUSSION: This prospective, level 3 cohort analysis demonstrates a non-significant survival advantage for patients transported by HEMS versus GEMS. Despite the large size of the cohort, the intrinsic mismatch in patient demographics limits the ability to statistically assess HEMS true benefit. It does, however, demonstrate an improved survival for patients attended by doctors on scene in addition to the GEMS response. Improvements in prehospital data and increased trauma unit reporting are required to accurately assess HEMS clinical and cost-effectiveness.

ABSTRACT

The Ankle Injury Management (AIM) trial was a pragmatic equivalence randomized controlled trial conducted at 24 hospitals in the United Kingdom that recruited 620 patients aged more than 60 years with an unstable ankle fracture. The trial compared the usual care pathway of early management with open reduction and internal fixation with initially attempting non-surgical management using close contact casting (CCC). CCC is a minimally padded cast applied by an orthopaedic surgeon after closed reduction in the operating theatre. The intervention groups had equivalent functional outcomes at six months and longer-term follow-up. However, potential barriers to using CCC as an initial form of treatment for these patients have been identified. In this report, the results of the AIM trial are summarized and the key issues are discussed in order to further the debate about the role of CCC. Evidence from the AIM trial supports surgeons considering conservative management by CCC as a treatment option for these patients. The longer-term follow-up emphasized that patients treated with CCC need careful monitoring in the weeks after its application to monitor maintenance of reduction.

ABSTRACT

OBJECTIVE: To determine whether an injection of platelet rich plasma improves outcomes after acute Achilles tendon rupture. DESIGN: Randomised, placebo controlled, two arm, parallel group, participant and assessor masked, superiority trial. SETTING: Secondary care trauma units across 19 hospitals in the United Kingdom's health service. PARTICIPANTS: Recruitment commenced in July 2015 and follow-up was completed in March 2018. 230 adults aged 18 years and over were included, with acute Achilles tendon rupture presenting within 12 days of injury and managed with non-surgical treatment. Exclusions were injury at the insertion or musculotendinous junction, major leg injury or deformity, diabetes mellitus, platelet or haematological disorder, systemic corticosteroids, anticoagulation treatment, and other contraindicating conditions. INTERVENTIONS: Participants were randomised 1:1 to platelet rich plasma (n=114) or placebo (dry needle; n=116) injection. All participants received standard rehabilitation care (ankle immobilisation followed by physiotherapy). MAIN OUTCOMES AND MEASURES: Primary outcome was muscle tendon function at 24 weeks, measured objectively with the limb symmetry index (injured/uninjured×100) in maximal work done during the heel rise endurance test (an instrumented measure of repeated single leg heel rises until fatigue). Secondary outcomes included patient reported function (Achilles tendon rupture score), quality of life (short form 12 version 2®), pain (visual analogue scale), goal attainment (patient specific functional scale), and adverse events. A central laboratory analysed the quality and content of platelet rich plasma. Analyses were by modified intention to treat. RESULTS: Participants were 46 years old on average, and 57 (25%) of 230 were female. At 24 weeks, 202 (88%) participants completed the heel rise endurance test and 216 (94%) the patient reported outcomes. The platelet rich plasma was of good quality, with expected growth factor content. No difference was detected in muscle tendon function between participants receiving platelet rich plasma injections and those receiving placebo injections (limb symmetry index, mean 34.7% (standard deviation 17.7%) v 38.5% (22.8%); adjusted mean difference -3.9% (95% confidence interval -10.5% to 2.7%)) or in any secondary outcomes or adverse event rates. Complier average causal effect analyses gave similar findings. CONCLUSIONS: There is no evidence to indicate that injections of platelet rich plasma can improve objective muscle tendon function, patient reported function, or quality of life after acute Achilles tendon rupture compared with placebo, or that they offer any patient benefit. TRIAL REGISTRATION: ISRCTN54992179.

ABSTRACT

INTRODUCTION: Ankle fractures result in significant morbidity in adults, with prognosis worsening with increasing age. Previous trials have not found evidence supporting supervised physiotherapy sessions, but these studies have not focused on older adults or tailored the exercise interventions to the complex needs of this patient group. The Ankle Fracture Treatment: Enhancing Rehabilitation study is a pilot randomised controlled trial to assess feasibility of a later definitive trial comparing best-practice advice with progressive functional exercise for adults aged 50 years and over after ankle fracture.The main objectives are to assess: (i) patient engagement with the trial, measured by the participation rate of those eligible; (ii) establish whether the interventions are acceptable to participants and therapists, assessed by intervention adherence levels, participant interviews and a therapist focus group; (iii) participant retention in the trial, measured by the proportion of participants providing outcome data at 6 months; (iv) acceptability of measuring outcomes at 3 and 6 month follow-up. METHODS AND ANALYSIS: A multicentre pilot randomised controlled trial with an embedded qualitative study. At least 48 patients aged 50 years and over with an ankle fracture requiring surgical management, or non-operative management by immobilisation for at least 4 weeks, will be recruited from a minimum of three National Health Service hospitals in the UK. Participants will be allocated 1:1 via a central web-based randomisation system to: (i) best-practice advice (one session of face-to-face self-management advice delivered by a physiotherapist and up to two optional additional sessions) or (ii) progressive functional exercise (up to six sessions of individual face-to-face physiotherapy). An embedded qualitative study will include one-to-one interviews with up to 20 participants and a therapist focus group. ETHICS AND DISSEMINATION: Hampshire B Research Ethics Committee (18/SC/0281) gave approval on 2nd July 2018. TRIAL REGISTRATION NUMBER: ISRCTN16612336.

ABSTRACT

OBJECTIVE: To predict functional outcomes 6 months after ankle fracture in people aged ≥60 years using post-treatment and 6-week follow-up data to inform anticipated recovery, and identify people who may benefit from additional monitoring or rehabilitation. DESIGN: Prognostic model development and internal validation. SETTING: 24 National Health Service hospitals, UK. METHODS: Participants were the Ankle Injury Management clinical trial cohort (n=618) (ISRCTN04180738), aged 60-96 years, 459/618 (74%) female, treated surgically or conservatively for unstable ankle fracture. Predictors were injury and sociodemographic variables collected at baseline (acute hospital setting) and 6-week follow-up (clinic). Outcome measures were 6-month postinjury (primary) self-reported ankle function, using the Olerud and Molander Ankle Score (OMAS), and (secondary) Timed Up and Go (TUG) test by blinded assessor. Missing data were managed with single imputation. Multivariable linear regression models were built to predict OMAS or TUG, using baseline variables or baseline and 6-week follow-up variables. Models were internally validated using bootstrapping. RESULTS: The OMAS baseline data model included: alcohol per week (units), postinjury EQ-5D-3L visual analogue scale (VAS), sex, preinjury walking distance and walking aid use, smoking status and perceived health status. The baseline/6-week data model included the same baseline variables, minus EQ-5D-3L VAS, plus five 6-week predictors: radiological malalignment, injured ankle dorsiflexion and plantarflexion range of motion, and 6-week OMAS and EQ-5D-3L. The models explained approximately 23% and 26% of the outcome variation, respectively. Similar baseline and baseline/6 week data models to predict TUG explained around 30% and 32% of the outcome variation, respectively. CONCLUSIONS: Predictive accuracy of the prognostic models using commonly recorded clinical data to predict self-reported or objectively measured ankle function was relatively low and therefore unlikely to be beneficial for clinical practice and counselling of patients. Other potential predictors (eg, psychological factors such as catastrophising and fear avoidance) should be investigated to improve predictive accuracy.

ABSTRACT

Major trauma systems have evolved in many European countries and have resulted in improved care in terms of mortality and morbidity. Many of the systems have similar history, with reports of either poor services, or a single disaster, driving change of policy and set up. We report on 4 European systems, looking at the background, set up and some of the results. Similar issues are identified including the importance of triage, the concentration of specialist skills which require patients to bypass hospitals, and the standardization of treatment protocols. The issues of rehabilitation and the increasing importance of measuring outcome with patient reported metrics are discussed.

ABSTRACT

BACKGROUND: Open fractures of the lower limb occur when a broken bone penetrates the skin and is exposed to the outside environment. These are life-changing injuries. The risk of deep infection may be as high as 27%. The type of dressing applied after surgical debridement could potentially reduce the risk of infection in the open-fracture wound. OBJECTIVES: To assess the disability, rate of deep infection, quality of life and resource use in patients with severe open fracture of the lower limb treated with negative-pressure wound therapy (NPWT) versus standard wound management after the first surgical debridement of the wound. DESIGN: A pragmatic, multicentre randomised controlled trial. SETTING: Twenty-four specialist trauma hospitals in the UK Major Trauma Network. PARTICIPANTS: A total of 460 patients aged ≥ 16 years with a severe open fracture of the lower limb were recruited from July 2012 through to December 2015. Patients were excluded if they presented more than 72 hours after their injury or were unable to complete questionnaires. INTERVENTIONS: Negative-pressure wound therapy (n = 226) where an 'open-cell' solid foam or gauze was placed over the surface of the wound and connected to a suction pump which created a partial vacuum over the dressing versus standard dressings not involving negative pressure (n = 234). MAIN OUTCOME MEASURES: Disability Rating Index (DRI) - a score of 0 (no disability) to 100 (completely disabled) at 12 months was the primary outcome measure, with a minimal clinically important difference of 8 points. The secondary outcomes were deep infection, quality of life and resource use collected at 3, 6, 9 and 12 months post randomisaton. RESULTS: There was no evidence of a difference in the patients' DRI at 12 months. The mean DRI in the NPWT group was 45.5 points [standard deviation (SD) 28.0 points] versus 42.4 points (SD 24.2 points) in the standard dressing group, giving a difference of -3.9 points (95% confidence interval -8.9 to 1.2 points) in favour of standard dressings (p = 0.132). There was no difference in HRQoL and no difference in the number of surgical site infections or other complications at any point in the 12 months after surgery. NPWT did not reduce the cost of treatment and it was associated with a low probability of cost-effectiveness. LIMITATIONS: Owing to the emergency nature of the interventions, we anticipated that some patients who were randomised into the trial would subsequently be unable or unwilling to take part. Such post-randomisation withdrawal of patients could have posed a risk to the external validity of the trial. However, the great majority of these patients (85%) were found to be ineligible after randomisation. Therefore, we can be confident that the patients who took part were representative of the population with severe open fractures of the lower limb. CONCLUSIONS: Contrary to the existing literature and current clinical guidelines, NPWT dressings do not provide a clinical or an economic benefit for patients with an open fracture of the lower limb. FUTURE WORK: Future work should investigate alternative strategies to reduce the incidence of infection and improve outcomes for patients with an open fracture of the lower limb. Two specific areas of potentially great benefit are (1) the use of topical antibiotic preparations in the open-fracture wound and (2) the role of orthopaedic implants with antimicrobial coatings when fixing the associated fracture.

ABSTRACT

BACKGROUND: There has been a recent steep growth in platelet-rich plasma (PRP) use for musculoskeletal conditions, but findings from high quality clinical trial data are lacking in the literature. Here, we describe the statistical analysis plan (SAP) for the Platelet-rich plasma in Achilles Tendon Healing 2 (PATH-2) trial. METHODS: PATH-2 is a pragmatic, parallel-group, multi-centre, double-blinded, randomised, placebo-controlled, superiority trial. The study aims to evaluate the clinical efficacy of PRP in acute Achilles tendon rupture in terms of muscle-tendon function. Patients are identified in the orthopaedic/trauma outpatient clinic. The primary outcome is muscle-tendon work capacity from the Heel Rise Endurance Test result, expressed as the Limb Symmetry Index (work, in joules), at 24 weeks post randomisation. Multivariate linear regression adjusting for the stratification factors (centre and age) and additional prognostic factors will be used to investigate the adjusted effect of the intervention. The analysis will be by modified intention-to-treat. Sensitivity analysis will assess the internal validity of the trial results by performing a per-protocol analysis. Safety will be summarised by treatment arm for all patients who started treatment. Secondary patient-reported outcome measures will be analysed using linear mixed effects models to allow all data collected at all follow-up points to be considered. Missing data will be summarised and reported by treatment arm. Missing data imputation will be performed, if appropriate. DISCUSSION: The PATH-2 trial will be reported in accordance with the CONSORT statement. This SAP publication will avoid bias arising from prior knowledge of the study results. Any changes or deviations from the current SAP will be described and justified in the final report. TRIAL REGISTRATION: ISRCTN registry: ISRCTN54992179 , assigned 12 January 2015.

ABSTRACT

BACKGROUND: Patients can struggle to make sense of trials in emergency situations. This study examines patient experience of participating in the United Kingdom, Wound management of Open Lower Limb Fractures (UK WOLLF) study, a trial of standard wound management versus Negative Pressure Wound Therapy (NPWT). METHODS: The aim of the study was to understand the patient's lived experience of taking part in a trial of wound dressings. Interviews drawing on Phenomenology were undertaken with a purposive sample of 20 patients, on average 12 days into their hospital stay from July 2012-July 2013. RESULTS: The participants were vulnerable due to the emotional and physical impact of injury. They expressed their trial experience through the theme of being compromised identified in categories of being dependent, being trusting, being grateful and being without experience. Participants felt dependent on and trusted the team to make the right decisions for them and not cause them harm. Their hopes for future recovery were also invested within the expertise of the team. Despite often not being well enough to consent to the study prior to surgery, they wished to be involved as much as possible. In agreeing to take part they expressed gratitude for their care, wanted to be helpful to others and considered the trial interventions to be a small component in relation to the enormity of their injury and broader treatment. In making sense of the trial they felt they could not understand the interventions without experience of them but if they received NPWT they developed a strong technological preference for this intervention. CONCLUSIONS: Patients prefer to be involved in studies within the limits of their capacity, despite not being able to provide informed consent. A variety of sources of knowledge may enable participants to feel that they have a better understanding of the interventions. Professional staff need to be aware of the situated nature of decision making where participants invest their hopes for recovery in the team.

ABSTRACT

PURPOSE: This systematic review aimed to reconceptualize experiences from a variety of papers to provide direction for research, policy and practice. METHOD: Meta-ethnography was used to inform the review, and 21 studies were included. FINDINGS: The analysis identified a core theme of "engaging in care: struggling through", as carers, who wanted to be involved in caring, learnt to live with the intense and stressful impact of caring and changes to their life. The core theme is represented through three themes (1) Helping another to live, (2) Adapting ways of living and (3) Negotiating the unknown. CONCLUSIONS: The discussion identified a focus on carers of people suffering from a hip fracture, the willingness of informal carers to engage in caring and the intense experience of adapting to changes in relationships and dependency alongside a steep experiential learning curve. Tensions exist in negotiations with complex health care systems as carers do not feel their expertise is valued and struggle to find and understand information. Implications for Rehabilitation Including relatives/carers in the umbrella of care within a family-centred approach. Involving relatives/carers within shared decision-making about care requirements and rehabilitation goals. Utilizing forms of experiential learning to help the development of relatives/carers skills in relation to their role as carer. Providing opportunities for carers to explore ways of sustaining their own health through self-compassion.

ABSTRACT

BACKGROUND: Trauma care in England was re-organised in 2012 with ambulance bypass of local hospitals to newly designated Major Trauma Centres (MTCs). There is still controversy about the optimal way to organise health series for patients suffering severe injury. METHODS: A longitudinal series of annual cross-sectional studies of care process and outcomes from April 2008 to March 2017. Data was collected through the national clinical audit of major trauma care. The primary analysis was carried out on the 110,863 patients admitted to 35 hospitals that were 'consistent submitters' throughout the study period. The main outcome was longitudinal analysis of risk adjusted survival. FINDINGS: Major Trauma networks were associated with significant changes in (1) patient flow (with increased numbers treated in Major Trauma Centres), (2) treatment systems (more consultant led care and more rapid imaging), (3) patient factors (an increase in older trauma), and (4) clinical care (new massive transfusion policies and use of tranexamic acid). There were 10,247 (9.2%) deaths in the 110,863 patients with an ISS of 9 or more. There were no changes in unadjusted mortality. The analysis of trends in risk adjusted survival for study hospitals shows a 19% (95% CI 3%-36%) increase in the case mix adjusted odds of survival from severe injury over the 9-year study period. Interrupted time series analysis showed a significant positive change in the slope after the intervention time point of April 2012 (+ 0.08% excess survivors per quarter, p = 0.023), in other words an increase of 0.08 more survivors per 100 patients every quarter. INTERPRETATION: A whole system national change was associated with significant improvements in both the care process and outcomes of patients after severe injury. FUNDING: This analysis was carried out independently and did not receive funding. The data collection for the national clinical audit was funded by subscriptions from participating hospitals.

ABSTRACT

BACKGROUND: Achilles tendon injuries give rise to substantial long-lasting morbidity and pose considerable challenges for clinicians and patients during the lengthy healing period. Current treatment strategies struggle to curb the burden of this injury on health systems and society due to lengthy rehabilitation, work absence and reinjury risk. Platelet-rich plasma (PRP) is an autologous preparation that has been shown to improve the mechanobiological properties of tendons in laboratory and animal studies. The use of PRP in musculoskeletal injuries is on the increase despite the lack of adequately powered clinical studies. METHODS AND DESIGN: This is a multicentre randomised controlled trial to evaluate the efficacy and mechanism of PRP in patients with acute Achilles tendon rupture (ATR). All adults with acute ATR presenting within 12 days of the injury who are to be treated non-operatively are eligible. A total of 230 consenting patients will be randomly allocated via a remote web-based service to receive PRP injection or placebo injection to the site of the injury. All participants will be blinded to the intervention and will receive standardised rehabilitation to reduce efficacy interference.Participants will be followed up with blinded assessments of muscle-tendon function, quality of life, pain and overall patient's functional goals at 4, 7, 13, 24 weeks and 24 months post-treatment. The primary outcome is the heel-rise endurance test (HRET), which will be supervised by a blinded assessor at 24 weeks. A subgroup of 16 participants in one centre will have needle biopsy under ultrasound guidance at 6 weeks. Blood and PRP will be analysed for cell count, platelet activation and growth factor concentrations. ETHICS AND DISSEMINATION: The protocol has been approved by the Oxfordshire Research Ethics Committee (Oxfordshire Research Ethics Committee A, reference no 14/SC/1333). The trial will be reported in accordance with the CONSORT statement and published in peer-reviewed scientific journals. TRIAL REGISTRATION NUMBER: ISRCTN: 54992179, assigned 12 January 2015. ClinicalTrials.gov: NCT02302664, received 18 November 2014. UK Clinical Research Network Study Portfolio Database: ID 17850.
