“Tiers of Delay” Warfarin, Hip Fractures, and Target-Driven Care

Anticoagulation reversal is a common cause of operative delay. We sought to establish for the first time the impact this has on best practice tariff (BPT) for patients with hip fracture admitted on warfarin. All patients with hip fracture treated operatively over a 32-month period were reviewed. Basic demographics, time to theater, length of stay, and mortality were recorded for all patients. Independent samples t-tests were used to identify statistically significant differences between patients on warfarin and those not taking the drug. A total of 83 patients were admitted anticoagulated with a mean international normalized ratio of 2.65 and a median time to theater of 49.7 hours. Of these patients, 79% breached BPT, incurring significant financial loss. In the control group, 908 patients took a median 24.5 hours, a 28% breach of BPT (P < .01). Length of stay, Nottingham Hip Fracture Score, and predicted 30-day mortality were similar for both the groups. As well as affecting clinical outcome following hip fracture, delay due to anticoagulation causes considerable loss of BPT. Potential loss of revenue due to delays over the study period was £80 000, inspiring the establishment of an “early trigger” anticoagulation protocol. Although it is accepted that there are limitations to this work, it should raise awareness of the real impact of warfarin on patients with hip fracture both in terms of outcome and for the first time, loss of potential revenue.

Human Bite Injury In North East England – The Impact Of Alcohol Intake On A Mode Of Violent Assault

Ninety-two retrospective cases of human bite injury referred to a Plastic Surgery department are presented. Particular emphasis is placed on the relationship of alcohol intake to these injuries, their distribution and subsequent management. A review of the literature is conducted. The human bite is a leisure time injury of the young single male in the North East. It has been shown that there is a clear link to alcohol and in particular weekend drinking. Prompt operative intervention and wounds located at the head and neck have been shown to be associated with a decreased risk of subsequent infection, which reflects findings in the earlier literature. Fifteen cases were infected. One was the result of a postoperative complication. The remainder were infected on admission. The majority of infected cases were upper limb bites and were associated with a delayed presentation.

Bending the curve: force health protection during the insertion phase of the Ebola outbreak response

After >10 years of enduring operations in Iraq and Afghanistan, Defence Strategic Direction is returning to a contingency posture. As the first post-Afghanistan operation, in September 2014, a UK Joint Inter-Agency Task Force deployed to Sierra Leone in response to the Ebola virus disease (EVD) epidemic in West Africa. The aims were expanding treatment capacity, assisting with training and supporting host nation resilience. The insertion phase of this deployment created a unique set of challenges for force health protection. In addition to the considerable risk of tropical disease and trauma, deployed personnel faced the risks of working in an EVD epidemic. This report explores how deployed medical assets overcame the difficulties of mounting a short-notice contingent operation in a region of the world with inherent major climatic and health challenges.

Spinal Fractures in Current Military Deployments

Objective To describe spinal fracture patterns presenting to deployed medical facilities during recent military operations. Methods Retrospective analysis of the United Kingdom Centre for Defence Imaging Computed Tomography database, 2005- 2009. Fractures are classified, mechanism noted and associated injuries recorded. Statistical analysis is by Fisher’s Exact test. Results 128 fractures in 57 casualties are analysed. Ballistic (79%) and non-ballistic mechanisms contribute to vertebral fracture at all regions of the spinal column in patients treated at deployed medical facilities. There is a high incidence of lumbar spine fractures, which are more likely to be due to explosion than gunshot wounding (p<0.05). Two thirds of thoracolumbar spine fractures caused by explosive devices are unstable and are mainly burst-fractures in configuration. 60% of spinal fracture patients had concomitant injuries. There is a strong relationship between spinal fractures caused by explosions and lower limb fractures. Conclusion Injuries to the spine caused by explosive devices account for greater numbers, greater associated morbidity and increasing complexity than other means of spinal injury managed in contemporary warfare. With the predominance of explosive injury in current conflict, this work provides the first detail of an evolving injury mechanism with implications for injury mitigation research.

Surgical advances during the First World War: the birth of modern orthopaedics.

The First World War (1914–1918) was the first truly industrial conflict in human history. Never before had rifle fire and artillery barrage been employed on a global scale. It was a conflict that over 4 years would leave over 750 000 British troops dead with a further 1.6 million injured, the majority with orthopaedic injuries. Against this backdrop, the skills of the orthopaedic surgeon were brought to the fore. Many of those techniques and systems form the foundation of modern orthopaedic trauma management. On the centenary of ‘the War to end all Wars’, we review the significant advances in wound management, fracture treatment, nerve injury and rehabilitation that were developed during that conflict.

Assessment and Early Management of Pain in Hip Fractures: The Impact of Paracetamol

Introduction: As the number of patients sustaining hip fractures increases, interventions aimed at improving patient comfort and reducing complication burden acquire increased importance. Frailty, cognitive impairment, and difficulty in assessing pain control characterize this population. In order to inform future care, a review of pain assessment and the use of preoperative intravenous paracetamol (IVP) is presented. Materials and Methods: Systematic review of preoperative IVP administration in patients presenting with a hip fracture. Results: Intravenous paracetamol is effective in the early management of pain control in the hip fracture population. There is a considerable decrease in use of breakthrough pain medications when compared with other pain relief modalities. Additionally, IVP reduces the incidence of opioid-induced complications, reduces length of stay, and lowers mean pain scores. Another significant finding of this study is the poor administration of all analgesics to patients with hip fracture with up to 72% receiving no prehospital analgesia. Discussion: The potential benefits of IVP as routine in the early management of hip fracture-related pain are clear. Studies of direct comparison between analgesia regimes to inform optimum bundles of analgesic care are sparse. This study highlights the need for properly constructed pathway-driven comparator studies of contemporary analgesia regimes, with IVP as a central feature to optimize pain control and minimize analgesia-related morbidity in this vulnerable population.

The use of foot pumps compression devices in the perioperative management of ankle fractures: Systematic review of the current literature

BACKGROUND Ankle fractures account for 9% of all fractures seen in the United Kingdom. 15,000 of these fractures undergo operative fixation each year. Soft tissue swelling impacts on timing of fixation due to fears of infection and wound dehiscence. The use of arterio-venous foot pumps (AVFP) is increasing in this population although the evidence for their efficacy is unclear. In order to address this, we present an overview of the evidence for AVFP device use following ankle fracture. METHODS In September 2015 an electronic literature search was undertaken of studies comparing two or more methods of swelling reduction in patients with ankle fractures. Of 326 screened, 5 papers ultimately were included. RESULTS Two studies reported a statistically significant reduction in swelling (p=0.03) and (p=0.03 at 24 hours, p=0.05 at 48 hours) after using AVFP devices compared to the controls (leg elevation +/ ice therapy). Stockle et al. reported a greater reduction in the preoperative ankle, midfoot and forefoot circumference at 24 hours in their AVFP group (53% versus 32% and 10% in their continuous cryotherapy and cool pack cryotherapy groups respectively). Whereas, Rohner-Spengler et al. observed improved preoperative swelling reduction in patients treated with a multilayer compression bandage when compared to their AVFP group. Keehan et al. reported that time to surgery was considerably reduced in patients treated with an AVFP device, (2.3 days) compared to those treated with leg elevation (4.6 days) (p=0.02). Length of stay (LOS) was not influenced by any of the tested interventions. CONCLUSIONS AVFP devices have been shown to reduce time to surgery and degree of swelling before operative intervention better than other methods but the strength of evidence to support this remains poor.

Factors Influencing patient experience and satisfaction following surgical management of ankle fractures

BACKGROUND Patient feedback is increasingly important to inform and develop effective healthcare within the United Kingdom. In order to optimise patient experience of ankle fracture care in our unit, we sought to identify elements of practice associated with poor patient experience and low levels of satisfaction. METHODS Adult patients with closed ankle fractures requiring fixation over a ten month period were prospectively identified. Prior to discharge all patients completed the Picker Patient Experience Questionnaire (PPE-15), satisfaction visual analogue scale (VAS: 0-10) and a demographic questionnaire. Operative delay and cancellation episodes were similarly noted. PPE-15 and satisfaction VAS data were collected concurrently from a control group of elective hip and knee arthroplasty patients. RESULTS 52 patients (23 males) of average age 47 years (17-86) underwent ankle fracture fixation. Median pre-operative length of stay (LOS) was 3days (IQR 1-6). Ankle fracture patients had significantly worse experiences compared to arthroplasty patients (p<0.05 across all 15 PPE domains). Once pre-operative length of stay exceeded 3days patients reported more areas of concerns (6 of 15) than those waiting 3days or less (4 of 15) (p=0.02). Cancelled patients reported significantly worse experiences, with satisfaction VAS of 7 (versus 9 in those not cancelled [p=0.005]), and median of 6 PPE-15 domains of concern (versus 3.5 [p=0.03]). CONCLUSIONS Efforts to improve the healthcare experience of patients with ankle fractures should be focused on improving processes that minimise cancellation of surgery and the communication around delay management.

The use of a validated pre-discharge questionnaire to improve the quality of patient experience of orthopaedic care

Patient experience is central to the delivery of excellent healthcare. As such it is enshrined within the 2015 NHS outcomes framework, a set of indicators against which quality in healthcare is measured. A variety of tools are available to quantify patient experience across clinical settings. When combined with a framework for continued data collection and suitable mechanisms for analysis, feedback, and intervention, these tools allow improvements in patient care and clinical services to be realised. In response to an increasing number of patient complaints and friends and family scores below the trust average within our orthopaedic department we instituted an improvement programme in March 2015. The programme was based around the Picker Patient Experience 15 questionnaire and aimed to improve friends and family test scores, reduce complaints and improve patient experience scores over an 18-month period. An improvement model including baseline measurement and 2 improvement cycles over an 18-month period was used. Initial benchmarks for practice were created by referencing national data allowing problem areas of care to be identified and interventions to address these developed. This process identified areas for improvement including improving staff awareness and engagement with patient experience, improving staff and patient communication and ensuring patients were aware and involved in plans for their own care. Actions to address these issues resulted in a 38% decrease in patient complaints, a >10% increase in patient experience, and improvements in patient satisfaction and friends and family scores.

Force protection in contingency operations: an evaluation of temperature monitoring in Sierra Leone.

Objectives The deployment of the UK-led Joint Inter-Agency Taskforce to Sierra Leone in September 2014 brought the era of contingency operations into focus. Daily health screening of such deployed personnel forms a key element of medical force protection. We have performed a service evaluation of an existing screening programme and detail the comparison of the two thermometers used in this role. Methods Data from the existing screening programme were used to inform a sample size required to enable statistically and clinically significant differences to be detected between the two interchangeably used thermometer systems in use. A prospective service evaluation on these devices was then carried out over a 10-day period and the data analysed by parametric tools. 10 personnel had their temperature recorded by both devices at the same time by a single operator every day. Results For the screened population, a mean temperature of 36.55°C and SD of 0.32°C was revealed. Powered to 80% with a two-tailed α of 0.05, the evaluation of the two thermometers revealed no significant difference between recordings taken with either device (p=0.115). The low SD meant that a pyrexial patient (>37.5°C) would require a recording over 3 SD from the population mean. Discussion Evaluations of medical force protection will carry increasing consequence as the UK deploy on short notice operations to regions of considerable endemic threat. Presence of pyrexia is a key early indicator of illness affecting deployed personnel, and two different thermometer types are provided for this function. We have shown for the first time with statistical and clinical significance that the two thermometers used in contingency force protection are interchangeable. The narrow variance is reassuring and confirms that the chosen trigger (>37.5°C) would warrant further investigation in the pyrexial patient.
