"Context, content, and system" supporting digital health hub (DHH)-enabled models of care (MoCs) for fragility hip fractures: perspectives of diverse multidisciplinary stakeholders in South Australia from qualitative in-depth interviews.

Combining thematic analysis and a human-computer persuasive systems framework suggests that hip fracture recovery among older people can be enhanced through person-centered digital health hub models of care focused on behavior change education and integrated care. The findings intend to guide settings involving comorbid conditions and low- and middle-income countries in developing innovative digital health solutions. PURPOSE: The purpose of this study was to understand stakeholders' perspectives on the development of a digital health-enabled model of care for fragility hip fractures and to map out factors that could influence the design and implementation of such a model. METHODS: Qualitative in-depth interviews were conducted with stakeholders from various clinical disciplines, allied health, and computer science. A hybrid process involving thematic analysis of the raw data using inductive coding was the first step. In the second step, the tenets of a theoretical framework (health behavior change supporting systems) were deductively applied to the thematic constructs generated as part of the first step of the analysis. RESULTS: In total, 24 in-depth interviews were conducted with stakeholders. We identified 18 thematic constructs presented under the categories of context, content, and system. Context covered patient characteristics such as frailty, digital literacy, and patient or carer participation, whereas healthcare delivery aspects included the structure and culture of existing practice and the need for innovative holistic models of care. Content outlines the active ingredients and approach in developing a digital health hub, and it highlights the importance of targeted education and behavior change. The system is a complicated matrix crossing different aspects of healthcare and offering a value proposition design through personalization across modes of content delivery. This must foster trust, ensure adequate financing, and support ownership and privacy by establishing appropriate mechanisms for embedding change. CONCLUSION: The findings from this study provide insights around potential factors related to patients, community support, and healthcare delivery influencing the design and next-stage implementation of a digital health hub model of care for fragility hip fractures.

Identifying Opportunities, and Motivation to Enhance Capabilities, Influencing the Development of a Personalized Digital Health Hub Model of Care for Hip Fractures: Mixed Methods Exploratory Study.

BACKGROUND: Most older people after a hip fracture injury never return to their prefracture status, and some are admitted to residential aged care facilities. Advancement of digital technology has helped in optimizing health care including self-management and telerehabilitation. OBJECTIVE: This study aims to understand the perspectives of older patients with hip fracture and their family members and residential aged caregivers on the feasibility of developing a model of care using a personalized digital health hub. METHODS: We conducted a mixed methods study in South Australia involving patients aged 50 years and older, their family members, and residential aged caregivers. Quantitative data analysis included basic demographic characteristics, and access to digital devices was analyzed using descriptive statistics. Spearman rank-order correlation was used to examine correlations between the perceived role of a personalized digital health hub in improving health and the likelihood of subsequent use. Findings from qualitative analysis were interpreted using constructs of capability, opportunity, and motivation to help understand the factors influencing the likelihood of potential personalized digital health hub use. RESULTS: This study recruited 100 participants-55 patients, 13 family members, and 32 residential aged caregivers. The mean age of the patients was 76.4 (SD 8.4, range 54-88) years, and 60% (33/55) of the patients were female. Approximately 50% (34/68) of the patients and their family members had access to digital devices, despite less than one-third using computers as part of their occupation. Approximately 72% (72/100) of the respondents thought that personalized digital health hub could improve health outcomes in patients. However, a moderate negative correlation existed with increasing age and likelihood of personalized digital health hub use (Spearman ρ=-0.50; P<.001), and the perceived role of the personalized digital health hub in improving health had a strong positive correlation with the likelihood of personalized digital health hub use by self (Spearman ρ=0.71; P<.001) and by society, including friends and family members (Spearman ρ=0.75; P<.001). Most patients (54/55, 98%) believed they had a family member, friend, or caregiver who would be able to help them use a personalized digital health hub. Qualitative analysis explored capability by understanding aspects of existing knowledge, including willingness to advance digital navigation skills. Access could be improved through supporting opportunities, and factors influencing intrinsic motivation were considered crucial for designing a personalized digital health hub-enabled model of care. CONCLUSIONS: This study emphasized the complex relationship between capabilities, motivation, and opportunities for patients, their family members, and formal caregivers as a patient networked unit. The next stage of research will continue to involve a cocreation approach followed by iterative processes and understand the factors influencing the development and successful integration of complex digital health care interventions in real-world scenarios.

Patient, surgical and hospital factors associated with the presence of a consultant surgeon during hip fracture surgery. Do we know the answer?

BACKGROUND: Provision of quality care can help to reduce adverse health outcomes following hip fracture. While surgical management by either a consultant or junior surgeon has shown inconclusive differences in patient outcomes, consultant presence is often recommended, yet little is known about the factors that influence whether a consultant surgeon is present during hip fracture surgery. The aim of this study is to examine patient, surgical and hospital factors associated with having a consultant surgeon present during hip fracture surgery. METHODS: An examination of hip fracture surgeries of adults aged ≥ 50 years admitted to hospitals in Australia and New Zealand between 1 January 2015 and 31 December 2018 using data from the Australia and New Zealand Hip Fracture Registry was conducted. Multivariable logistic regression was used to examine factors associated with the presence of a consultant surgeon during hip fracture surgery. RESULTS: There were 29 530 hip fracture surgeries 58.1% had a consultant surgeon present (range 8.5-100% by hospital). Patients were more likely to have a consultant surgeon present during surgery if they had private health insurance, were operated on after hours, required total hip replacements or were operated on in hospitals that conducted ≤150 surgeries per year. CONCLUSION: There is variation in the presence of consultant surgeons within Australia and New Zealand during hip fracture surgery, potentially associated with the complexity of surgery and hospital factors. However, further research is needed to determine the optimum level of supervision required based on patient factors and surgical complexity.

Personal digital health hubs for multiple conditions.

Multimorbidity is the presence of more than one chronic disease condition in an individual. Health-related, socioeconomic, cultural and environmental factors, as well as patient behaviour, all influence the outcomes of multimorbidity. Addressing these complex and often interacting biopsychosocial factors therefore requires a shift in treatment from a physical damage model towards person-centred integrated care with increased patient agency. Education influences behaviour and can be used to empower patients and their carers with greater agency, thus allowing greater responsibility for and control over the management of patient care. In this paper we reflect on our own learning as a community of health practitioners from different disciplines. Recognizing the increasing importance of patient agency in driving the evolution of health care, we describe the concept of a web-based personal digital health hub for integrated patient care. Informed by collaboration between patient, health and education communities, we share our early experience in the implementation of a health hub around a cohort of patients with hip fractures. We also describe a vision for future health care based on the co-creation of digital health hubs centred on patients' and carers' needs. The health hub could allow important advances and efficiencies to be achieved in workforce practice and education; patient and carer engagement in self-care; and the collection of patient-reported health data required for ongoing research and improvements in health care.

La multimorbidité est la présence de plus d'une maladie chronique chez un individu. L'aboutissement de la multimorbidité est influencé par des facteurs sanitaires, socio-économiques, culturels et environnementaux. Aborder ces facteurs biopsychosociaux complexes et souvent interdépendants requiert donc un changement de traitement, qui consiste à s'éloigner d'un modèle axé sur les dommages physiques pour se rapprocher d'un modèle de soins intégré et centré sur la personne, allié à une meilleure implication du patient. L'éducation a un impact sur le comportement et peut être utilisée pour renforcer la capacité d'agir des patients et de leurs soignants, ce qui permettra de conférer plus de responsabilités et un meilleur contrôle de la gestion des soins aux patients. Dans ce document, nous réfléchissons à notre propre apprentissage en tant que communauté de professionnels de la santé issus de différentes disciplines. Nous reconnaissons l'importance croissante de l'implication du patient pour stimuler l'évolution des soins de santé, et imaginons un concept de centre de santé numérique et personnalisé via site Web pour la prise en charge intégrée des patients. Grâce à la collaboration entre patients, professionnels de la santé et structures pédagogiques, nous partageons nos premières expériences en matière de mise en œuvre d'un centre de santé regroupant des patients présentant des fractures de la hanche. Nous dévoilons également notre vision d'avenir pour les soins de santé, qui repose sur la cocréation de centres de santé numériques adaptés aussi bien aux besoins des patients qu'à ceux des soignants. Ce concept pourrait faire progresser l'enseignement et la pratique pour les professionnels du secteur, mais aussi améliorer leur efficacité; favoriser la participation des patients et soignants dans les soins auto-administrés; et enfin, permettre la collecte des données fournies par les patients, et nécessaires à la poursuite des recherches et améliorations dans le domaine des soins de santé.

La multimorbilidad es la presencia de más de una enfermedad crónica en un individuo. Los factores medioambientales, culturales, socioeconómicos y los relacionados con la salud, así como el comportamiento de los pacientes, influyen en los resultados de la multimorbilidad. Por lo tanto, se requiere un cambio en el tratamiento desde el modelo de daño físico hacia una atención integrada y centrada en el individuo con una mayor participación del paciente para abordar estos factores biopsicosociales complejos y a menudo interactivos. La educación influye en el comportamiento y se puede utilizar para que los pacientes y sus cuidadores tengan más capacidad de acción, lo que permite una mayor responsabilidad y control sobre la gestión de la atención al paciente. En este documento reflexionamos sobre nuestro propio aprendizaje como comunidad de profesionales de la salud de diferentes disciplinas. Se describe el concepto de un centro de salud virtual personalizado para la atención integrada del paciente, al reconocer la creciente relevancia de la participación y la acción del paciente en el proceso de evolución de la atención médica. Gracias a la colaboración entre las comunidades de pacientes, de salud y de educación, compartimos nuestra experiencia inicial sobre el establecimiento de un centro de salud en torno a una cohorte de pacientes con fracturas de cadera. Asimismo, describimos una visión de la futura atención médica basada en la creación conjunta de centros de salud virtuales que se centran en las necesidades de los pacientes y de los cuidadores. El centro de salud permitiría alcanzar importantes avances y mejoras en la práctica y la educación de la fuerza de trabajo; en el compromiso de los pacientes y los cuidadores con el autocuidado de la salud; y en la recopilación de los datos sobre la salud que los pacientes comunican y que se requieren para la investigación y las mejoras continuas en la atención médica.

Innovations to improve access to musculoskeletal care.

Innovation is a form of realising a new way of doing something, often ignoring traditional wisdom, in order to meet new challenges. Globally, particularly in emerging economies, the high burden of musculoskeletal conditions and their contribution to multimorbidity continue to rise, as does the gap for services to deliver essential care. There is a growing need to find solutions to this challenge and deliver person-centred and integrated care, wherein empowering patients with the capacity for self-management is critical. Whilst there is an abundance of information available online to support consumer education, the number of sources for credible medical information is diluted by uninformed anecdotal social media solutions. Even with the provision of high-quality information, behavioural change does not necessarily follow, and more robust educational approaches are required. In this chapter, we examine innovation, its management and the strategic directions required to improve musculoskeletal healthcare at macro (policy), meso (service delivery) and micro (clinical practice) levels. We discuss the critical role of consumer agency (patients and their families/carers) in driving innovation and the need to leverage this through empowerment by education. We provide a snapshot of real-world examples of innovative practices including capacity building in consumer and interprofessional musculoskeletal education and practice; recommendations to transform the access and delivery of integrated, person-centred care; and initiatives in musculoskeletal care and implementation of models of care, enabled by digital health solutions including telehealth, remote monitoring, artificial intelligence, blockchain technology and big data. We provide emerging evidence for how innovation can support systems' strengthening and build capacity to support improved access to 'right' musculoskeletal care, and explore some of the ways to best manage innovations. We conclude with recommended systematic steps to establish required leadership, collaboration, research, networking, dissemination, implementation and evaluation of future innovations in musculoskeletal health and care.

Orthopaedic surgeons' perceptions of frailty and frailty screening.

BACKGROUND: Over the past decade, there has been significant growth in the awareness and understanding of fragility among orthopaedic surgeons in the context of osteoporotic fractures and with it, improvements in the recognition and management of fragility fractures. Emerging as a major clinical and research focus in aged care is the concept of frailty and its associations with fragility, sarcopenia, falls and rehabilitation. Currently, research is lacking on how orthopaedic surgeons perceive frailty and the role of frailty screening. A baseline understanding of these perceptions is needed to inform integration of frailty identification and management for patient optimization in orthopaedic practices, as well as research and education efforts of patients and healthcare professionals in orthopaedic contexts. METHODS: We used an exploratory design guided by qualitative description to conduct 15 semi-structured telephone and in-person interviews across three orthopaedic surgeon subgroups (Registrars, Junior Consultants, and Senior Consultants). Data collection and analysis occurred iteratively and was guided by thematic saturation. RESULTS: Orthopaedic surgeons have a disparate understanding of frailty. Between colleagues, frailty is often referred to non-specifically to suggest a general state of risk to the patient. Frailty screening is regarded positively but its specific utility in orthopaedic environments is questioned. Easy-to-administer frailty screening tools that are not exclusive assessments of functional status are viewed most satisfactorily. However these tools are rarely used. CONCLUSIONS: There is little understanding among orthopaedic surgeons of frailty as a phenotype. Beliefs around modifiability of frailty were dissimilar as were the impact of related risk factors, such a cognitive status, chronic disease, social isolation, and environmental influences. This in turn may significantly impact on the occurrence and treatment outcomes of fragility fracture, a common orthopaedic problem in older populations. This study highlights need for knowledge translation efforts (e.g. education) to achieve cohesive understanding of frailty among health professionals.

A global perspective on the challenges and opportunities in learning about rheumatic and musculoskeletal diseases in undergraduate medical education : White paper by the World Forum on Rheumatic and Musculoskeletal Diseases (WFRMD).

Rheumatic and musculoskeletal diseases (RMDs) encompass a spectrum of degenerative, inflammatory conditions predominantly affecting the joints. They are a leading cause of disability worldwide and an enormous socioeconomic burden. However, worldwide deficiencies in adult and paediatric RMD knowledge among medical school graduates and primary care physicians (PCPs) persist. In October 2017, the World Forum on Rheumatic and Musculoskeletal Diseases (WFRMD), an international think tank of RMD and related experts, met to discuss key challenges and opportunities in undergraduate RMD education. Topics included needs analysis, curriculum content, interprofessional education, teaching and learning methods, implementation, assessment and course evaluation and professional formation/career development, which formed a framework for this white paper. We highlight a need for all medical graduates to attain a basic level of RMD knowledge and competency to enable them to confidently diagnose, treat/manage or refer patients. The importance of attracting more medical students to a career in rheumatology, and the indisputable value of integrated, multidisciplinary and multiprofessional care are also discussed. We conclude that RMD teaching for the future will need to address what is being taught, but also where, why and to whom, to ensure that healthcare providers deliver the best patient care possible in their local setting.

Cocreation of a digital patient health hub to enhance education and person-centred integrated care post hip fracture: a mixed-methods study protocol.

INTRODUCTION: Older people with hip fractures often require long-term care and a crucial aspect is the provision of quality health information to patients and their carers to support continuity of care. If patients are well informed about their health condition and caring needs, particularly posthospital discharge into the community setting, this may support recovery and improve quality of life. As internet and mobile access reach every household, it is possible to deliver a new model of service using a digital education platform as a personal health hub where both patients and their providers of care can establish a more efficient information integration and exchange process. This protocol details proposed research, which aims to develop a 'model of care' by using a digital health solution that will allow delivery of high quality and patient-centred information, integrated into the existing process delivered within the community setting. METHODS AND ANALYSIS: This phase of the study uses a pragmatic mixed-methods design and a participatory approach through engagement of patients, their carers and healthcare providers from multiple disciplines to inform the development of a digital health platform. Quantitative methods will explore health literacy and e-health literacy among older people with hip fractures admitted to the two public tertiary care hospitals in Adelaide, South Australia. Qualitative methods will provide an understanding of aspects of content and context required for the digital health platform to be developed in order to deliver quality health information. The study will use appropriate theoretical frameworks and constructs to guide the design, analysis and overall conduct of the research study. The scope of the study intends to ultimately empower patients and their carers to improve self-management and to better use coordinated services at the community level. This could prevent further falls including associated injuries or new fractures; reduce new hospital admissions and improve confidence and engagement by limiting the psychologically restrictive 'fear of falls'. ETHICS AND DISSEMINATION: The study has been approved by the Human Research Ethics Committee of the Central Adelaide Local Health Network, South Australia (SA) Health, Government of South Australia and the University of Adelaide Human Research Ethics Committee. Findings from the study will be published in suitable peer-reviewed journals and disseminated through workshops or conferences.

Testing the Hip Abductor Muscle Strength of Older Persons Using a Handheld Dynamometer.

OBJECTIVE: To investigate the reliability of a clinically applicable method of dynamometry to assess and monitor hip abductor muscle strength in older persons. DESIGN: Bilateral isometric hip abductor muscle strength measured with a handheld dynamometer, patients supine with the contralateral hip positioned directly against a wall for stabilization. Reliability determined by comparing intra-assessor and inter-assessor results and comparison to a criterion standard (stabilized dynamometer with patients in the standing position). SETTING: UniSA Nutritional Physiology Research Centre. PARTICIPANTS: Twenty-one patients older than 65 years were recruited from the Royal Adelaide Hospital. MAIN OUTCOME MEASURES: Intraclass correlation coefficients (ICCs), bias, and limits of agreement calculated to determine reliability. RESULTS: Intra-assessor and inter-assessor ICCs were high (0.94 and 0.92-0.94, respectively). There was no intra-assessor bias and narrow limits of agreement (±2.4%). There was a small inter-assessor bias but narrow limits of agreement (0.6%-0.9% and ± 2.3%, respectively). There was a wide variation comparing results to the criterion standard (±5.0%-5.2% limits of agreement), highlighting problems attributed to difficulties that the test population had with the standing position used in the criterion standard test. CONCLUSIONS: Testing older persons' hip abductor muscle strength while in the supine position with optimal pelvic stabilization using a handheld dynamometer is highly reliable. While further studies must be done to assess patients with specific pathologies, this test has potential application to monitor and evaluate the effects of surgical interventions and/or rehabilitation protocols for a variety of conditions affecting hip abductor function such as hip fractures and arthritis.

Perspectives of Frailty and Frailty Screening: Protocol for a Collaborative Knowledge Translation Approach and Qualitative Study of Stakeholder Understandings and Experiences.

BACKGROUND: Accompanying the unprecedented growth in the older adult population worldwide is an increase in the prevalence of frailty, an age-related clinical state of increased vulnerability to stressor events. This increased vulnerability results in lower social engagement and quality of life, increased dependency, and higher rates of morbidity, health service utilization and mortality. Early identification of frailty is necessary to guide implementation of interventions to prevent associated functional decline. Consensus is lacking on how to clinically recognize and manage frailty. It is unknown how healthcare providers and healthcare consumers understand and perceive frailty, whether or not they regard frailty as a public health concern; and information on the indirect and direct experiences of consumer and healthcare provider groups towards frailty are markedly limited. METHODS: We will conduct a qualitative study of consumer, practice nurse, general practitioner, emergency department physician, and orthopedic surgeons' perspectives of frailty and frailty screening in metropolitan and non-metropolitan South Australia. We will use tailored combinations of semi-structured interviews and arts-based data collection methods depending on each stakeholder group, followed by inductive and iterative analysis of data using qualitative description. DISCUSSION: Using stakeholder driven approaches to understanding and addressing frailty and frailty screening in context is critical as the prevalence and burden of frailty is likely to increase worldwide. We will use the findings from the Perceptions of Frailty and Frailty Screening study to inform a context-driven identification, implementation and evaluation of a frailty-screening tool; drive awareness, knowledge, and skills development strategies across stakeholder groups; and guide future efforts to embed emerging knowledge about frailty and its management across diverse South Australian contexts using a collaborative knowledge translation approach. Study findings will help achieve a coordinated frailty and healthy ageing strategy with relevance to other jurisdictions in Australia and abroad, and application of the stakeholder driven approach will help illuminate how its applicability to other jurisdictions.

Outcomes between older adults with atypical and typical femoral fractures are comparable.

INTRODUCTION: Atypical femoral fractures (AFFs) are rare but a serious complication associated with prolonged use of bisphosphonates. However little is known about clinical outcomes of AFFs. The aim of this study is to compare the characteristics and postoperative outcomes between older patients with AFFs and typical femoral fractures (TFFs). METHODS: A retrospective matched cohort study (each AFF was age- and sex-matched with three TFFs) of patients aged 65 years or older who were admitted to The Queen Elizabeth Hospital, South Australia between January 2011 and December 2013 was undertaken. Baseline characteristics of both groups were compared. The primary outcomes evaluated were level of independence in mobility at discharge and 3 months after surgery. Secondary outcomes included length of hospital stay, post-operative complications, rate of surgical revision, discharge destination (after acute hospital stay or rehabilitation), 28-day hospital readmission and 12-month mortality. RESULTS: Ten patients (mean age: 78.1 years) with AFFs were compared with 30 matched TFFs. Patients with AFFs were predominantly female (90%) and 80% had been taking oral bisphosphonate. Nine of the AFFs had their fractures fixed with an intramedullary (IM) nail. The level of independent mobility at discharge (OR 0.31; 95%CI: 0.06-1.71; p=0.26) and at 3 months (OR 0.51; 95%CI: 0.10-2.53; p=0.47) were comparable between the two groups. Only one AFF patient treated with plate and screws required surgical revision, compared with none in the TFF group. Secondary outcomes were not significantly different between the two groups. CONCLUSION: Recovery of mobility and reoperation rates after surgery of patients with AFFs were favourable and did not differ significantly from TFFs. Further consideration should be given to using IM fixation in the management of AFFs in older people.

Influence of Fracture Stability on Early Patient Mortality and Reoperation After Pertrochanteric and Intertrochanteric Hip Fractures.

OBJECTIVES: To determine the influence of fracture stability on early patient mortality and complications requiring reoperation after trochanteric hip fracture. DESIGN: Prospective consecutive cohort study. SETTING: The orthopaedic unit of a public teaching hospital. PARTICIPANTS: Seven hundred twenty-eight patients with 743 consecutive stable (n = 446) pertrochanteric and unstable (n = 297) pertrochanteric or intertrochanteric fractures (median age: 84 years, 71% females) resulting from a low-impact injury and surgically managed. Mean follow-up of surviving patients was 4 years (range: 2-6 years). INTERVENTION: Fracture fixation by dynamic hip screw extramedullary device or intramedullary nail (Austofix or Gamma3) based on surgeon preference. MAIN OUTCOME MEASURES: Mortality within 6 and 12 months and surgical complications requiring device reoperation within 12 months of surgery (multivariate logistic regression and Kaplan-Meier survival analyses). RESULTS: Patients with unstable fractures were at 1.61 times (95% confidence interval: 1.18-2.21, P = 0.003) and 1.37 times (95% confidence interval: 1.02-1.83, P = 0.037) greater odds of dying within 6 and 12 months, respectively, than those with stable fractures. Older age, male gender, higher American Society of Anesthesiologists classification, in residential care, and inpatient-reported medical complications were also independent risk factors for early mortality. Increasing fracture instability and fixation using the Austofix nail were associated with early device reoperation. Comparable results were reported for the dynamic hip screw and Gamma3 nail, although the Gamma3 nail may offer advantages for more complex unstable fractures. CONCLUSIONS: Fracture instability influences early mortality after surgical fixation of trochanteric hip fracture. The Austofix double lag screw device had suboptimal results. LEVEL OF EVIDENCE: Prognostic Level II. See Instructions for Authors for a complete description of levels of evidence.

The accuracy and precision of radiostereometric analysis in monitoring tibial plateau fractures.

BACKGROUND AND PURPOSE: The application of radiostereometric analysis (RSA) to monitor stability of tibial plateau fractures during healing is both limited and yet to be validated. We therefore evaluated the accuracy and precision of RSA in a tibial plateau fracture model. METHODS: Combinations of 3, 6, and 9 markers in a lateral condyle fracture were evaluated with reference to 6 proximal tibial arrangements. Translation and rotation accuracy was assessed with displacement-controlled stages, while precision was assessed with dynamic double examinations. A comparison of error according to marker number and arrangement was completed with 2-way ANOVA models. RESULTS: The results were improved using more tantalum markers in each segment. In the fracture fragment, marker scatter in all axes was achieved by a circumferential arrangement (medial, anterior, and lateral) of the tantalum markers above the fixation devices. Markers placed on either side of the tibial tuberosity and in the medial aspect of the fracture split represented the proximal tibial reference segment best. Using 6 markers with this distribution in each segment, the translation accuracy (root mean square error) was less than 37 mum in all axes. The precision (95% confidence interval) was less than +/- 16 mum in all axes in vitro. Rotation, tested around the x-axis, had an accuracy of less than 0.123 degrees and a precision of +/- 0.024 degrees. INTERPRETATION: RSA is highly accurate and precise in the assessment of lateral tibial plateau fracture fragment movement. The validation of our center's RSA system provides evidence to support future clinical RSA fracture studies.

The subcristal pelvic external fixator: technique, results, and rationale.

We report a new technique for pelvic external fixation that we have developed as an alternative to the anterosuperior (Slätis) and the anteroinferior (supra-acetabular) type pelvic external fixator configurations. The method principally differs from the other techniques by virtue of the subcristal positioning of the pins and offers advantages in terms of easier pin placement, less skin irritation, less pin tract infection and loosening, and less interference with hip flexion, while allowing dressing, sitting, and walking. Between 1992 and 2006, we successfully used subcristal pelvic external fixators as the definitive fixation device for 20 patients with pelvic ring disruptions. The only complications encountered were superficial pin tract infections in 4 patients (20%) who were successfully treated with wound care and antibiotics.

Differentially loaded radiostereometric analysis to monitor fracture stiffness: a feasibility study.

Inability to accurately and objectively assess the mechanical properties of healing fractures in vivo hampers clinical fracture management and research. We describe a method to monitor fracture stiffness during healing in a clinical research setting by detecting changes in fracture displacement using radiostereometric analysis and simultaneously measuring applied axial loads. A method was developed for load application, positioning of the patient, and radiographic setup to establish the technique of differentially loaded radiostereometric analysis (DLRSA). A DLRSA examination consists of radiostereometric analysis radiographs taken without load (preload), under different increments of load, and without load (postload). Six patients with distal femur fractures had DLRSA examinations at 6, 12, 18, and 26 weeks postoperatively. The DLRSA method was feasible in a clinical setting. The method provides objective and quantifiable data for internally fixed fractures and may be used in clinical research as a tool to monitor the in vivo stiffness of healing femoral fractures managed with nonrigid internal fixation.

Surgical education and training in Australia and New Zealand.

Surgical education for medical students in Australia and New Zealand is provided by 19 universities in Australia and 2 in New Zealand. One surgical college is responsible for managing the education, training, assessment, and professional development programs for surgeons throughout both countries. The specialist surgical associations and societies act as agents of the college in the delivery of these programs, the extent of which varies among specialties. Historically, surgical training was divided into basic and specialist components with selection required for each part. In response to a number of factors, a new surgical education and training program has been developed. The new program incorporates a single merit-based national selection directly into the candidate's specialty of choice. The existing curriculum for each of the nine specialties has been remodeled to a competence-based format in line with the competence required to undertake the essential roles of a surgeon. New standards and criteria have been produced for accreditation of health care facilities used for training. A new basic surgical skills education and training course has been developed, with simulation playing an increasing role in all courses. Trainees' progress is assessed by workplace-based assessment and formal examinations, including an exit examination. The sustained production of sufficient competent surgeons to meet societal needs encompasses many challenges including the recruitment of appropriate graduates and the availability of adequate educational and clinical resources to train them. Competence-based training is an attractive educational philosophy, but its implementation has brought its own set of issues, many of which have yet to be resolved.

Development of the Australian Core Competencies in Musculoskeletal Basic and Clinical Science project - phase 1.

Musculoskeletal conditions are a major contributor to the burden of disease globally and their impact is predicted to increase. Consistent with findings in other countries, the current standard of musculoskeletal education in Australian medical schools is inadequate to meet today's musculoskeletal care requirements. A national multidisciplinary approach unifying the key musculoskeletal clinical and basic science disciplines has been adopted to provide clear, evidence-based education guidelines that are specifically aimed at priority musculoskeletal conditions; a direct link is therefore established between community health care needs and education at a national level. This "top-down" approach provides the potential for a far more effective and efficient delivery of musculoskeletal education by allowing the identification of the key basic knowledge and skills required to achieve core competencies and by providing appropriate direction for students. The Australian Core Competencies in Musculoskeletal Basic and Clinical Science are being developed for medical schools to incorporate into their curricula, with the ultimate aim of improving the standard of health care for Australians with musculoskeletal conditions.
