Define, Inform, Dictate and Deliver

YesIn October 2014, Simon Stevens, the chief executive of NHS England, committed the service to plugging £22 billion of the expected £30 billion gap in its finances by 2020 through productivity gains of 2–3% a year by 2020. Since that announcement, the Government promised to provide £8 billion by 2020. This may notionally have been received, but it has not alleviated the severity of these financial constraints (Barnes and Dunhill, 2015). With austerity measures biting even deeper into the budgets of NHS organisations, all staff are under pressure to make cost efficiencies and at the same time improve operational standards and patient outcomes. In this pressured change environment, there are hospitals and departments that have embraced the demand for change, creating innovative skills mix platforms from which to deliver services. But there are also those who have remained entrenched in operational protocols. In both scenarios, the overarching driver for service re-design has been operational efficiency guided by government targets

Artificial intelligence in diagnostic imaging: impact on the radiography profession

YesThe arrival of artificially intelligent systems into the domain of medical imaging has focused attention and sparked much debate on the role and responsibilities of the radiologist. However, discussion about the impact of such technology on the radiographer role is lacking. This paper discusses the potential impact of artificial intelligence (AI) on the radiography profession by assessing current workflow and cross-mapping potential areas of AI automation such as procedure planning, image acquisition and processing. We also highlight the opportunities that AI brings including enhancing patient-facing care, increased cross-modality education and working, increased technological expertise and expansion of radiographer responsibility into AI-supported image reporting and auditing roles

There’s nothing plain about projection radiography! A discussion paper

YesObjectives: Unlike the technological advances in cross-sectional imaging, the adoption of CR and DR has been relatively overlooked in terms of the additional radiographer skills and competences required for optimal practice. Furthermore, projection radiography is often referred to as basic, plain or other words suggesting simplicity or entry-level skill requirements. Radiographers’ professional identity is connected with the discourse expressed via the language used in daily practice and consequently, if the perception of projection radiography is regarded as simple practice not requiring much reflection or complex decision-making, apathy and carelessness may arise. The purpose of this narrative review was to raise projection radiography from its longstanding lowly place and re-position it as a specialist imaging field. Key findings: Danish pre-registration radiography curricula contain little mention of projection radiography and a low proportion (n ¼ 17/144; 11.8%) of Danish radiography students chose to focus on projection radiography within publicly available BSc. theses between 2016 and 2020 as compared to topics related to CT and MRI (n ¼ 60/144; 41.7%). Conclusion: By changing how we as the profession perceive the role and position of projection radiography, we can start to rebuild its lost prestige and demand a greater, more detailed and clinically relevant educational offering from academic partners. For this to commence, the language and terminology we use to describe ourselves and tasks undertaken must reflect the complexity of the profession. Implications for practice: Regardless of imaging modality, every patient should be assured that a radiographer with expertise in acquiring images of diagnostic quality undertakes their examination. Reclaiming the prestige of projection radiography may lead students and radiographers to recognize projection radiography as a demanding specialist field for the benefit of the patients

Local diagnostic reference levels for skeletal surveys in suspected physical child abuse

NoIntroduction: The purpose was to determine if an age based, local diagnostic reference level for paediatric skeletal surveys could be established using retrospective data. Methods: All children below two years of age referred for a primary skeletal survey as a result of suspected physical abuse during 2017 or 2018 (n ¼ 45) were retrospectively included from a large Danish university hospital. The skeletal survey protocol included a total of 33 images. Dose Area Product (DAP) and acquisition parameters for all images were recorded from the Picture Archival and Communication System (PACS) and effective dose was estimated. The 75th percentile for DAP was considered as the diagnostic reference level (DRL). Results: The 75th percentile for DAP was 314 mGy*cm2 , 520 mGy*cm2 and 779 mGy*cm2 for children <1 month, 1e11 months and 12 < 24 months of age respectively. However, only the age group 1e11 months had a sufficient number of children (n ¼ 27) to establish a local DRL. Thus, for the other groups the DAP result must be interpreted with caution. Effective dose was 0.19, 0.26 and 0.18 mSv for children <1, 1e11 months and 12 < 24 months of age respectively. Conclusion: For children between 1 and 11 months of age, a local diagnostic reference level of 520 mGy*cm2 was determined. This may be used as an initial benchmark for primary skeletal surveys as a result of suspected physical abuse for comparison and future discussion. Implications for practice: While the data presented reflects the results of a single department, the suggested diagnostic reference level may be used as a benchmark for other departments when auditing skeletal survey radiation dose

The use of history to identify anterior cruciate ligament injuries in the acute trauma setting: the 'LIMP index'

YesObjective To identify the injury history features reported by patients with ACL injuries and determine whether history may be used to identify patients requiring follow-up appointments from acute trauma services. Multi-site cross-sectional service evaluation using a survey questionnaire design conducted in the UK. The four injury history features investigated (LIMP) were ‘Leg giving way at the time of injury’, ‘Inability to continue activity immediately following injury’, ‘Marked effusion’ and ‘Pop (heard or felt) at the time of injury’. 194 patients with ACL injury were identified of which 165 (85.5%) attended an acute trauma service. Data on delay was available for 163 (98.8%) of these patients of which 120 (73.6%) had a follow-up appointment arranged. Patients who had a follow-up appointment arranged waited significantly less time for a correct diagnosis (geometric mean 29 vs 198 days; p<0.001) and to see a specialist consultant (geometric mean 61 vs 328 days; p<0.001). Using a referral threshold of any 2 of the 4 LIMP injury history features investigated, 95.8% of patients would have had a follow-up appointment arranged. Findings support the value of questioning patients on specific injury history features in identifying patients who may have suffered ACL injury. Using a threshold of 2 or more of the 4 LIMP history features investigated would have reduced the percentage of patients inappropriately discharged by 22.2%. Evidence presented suggests that this would significantly reduce the time to diagnosis and specialist consultation minimising the chance of secondary complications

Evaluating the role of the diagnostic radiographer in identifying child safeguarding concerns: A knowledge, attitude and practice survey approach

YesIntroduction: Child safeguarding and the appropriate identification of suspected victims represents a global phenomenon. Diagnostic imaging is acknowledged as a contributory diagnostic service but the role of the radiographer in the identification and escalation process is less well understood. Method: A Knowledge, Attitude and Practice (KAP) survey was constructed to evaluate knowledge base in the context of the patient–radiographer interaction, the shaping of attitude towards child safeguarding and attitudes held towards their role plus the actual practical experiences of managing child safeguarding concerns. Results: Respondents demonstrated a inconsistent knowledge base with respect to physical, social and radiographic signs and symptoms of child safeguarding concern. A positive attitude towards the role of the radiographer in child safeguarding was demonstrated but one that was shaped more by experience than pre-registration education. Assessment of concerns was chiefly influenced by clinical history and appreciation of aetiology. Practically, radiographers have infrequent involvement with the identification and escalation of concerns. Whilst some statistically significant relationships between responses and demographics did exist, these were either sporadic or argued to be a result of natural variation. Conclusion: Assessment of physical and social signs of child safeguarding concern are argued to be becoming more challenging. Radiological signs continue to be visible to radiographers but with increasing use of other imaging modalities these signs are becoming more varied in nature and are providing new challenges. Radiographers are capable of escalation when required to do so. Implications for practice: To maximise the contribution of the profession, education needs to account for imaging modality worked with, in combination with an understanding of related aetiology. Previously existing concerns with respect to escalating processes are no longer in evidence and radiographers are both willing and able to contribute to that process

Advanced Practice: Research Report

yesThe Health Care and Professions Council (HCPC) regulates fifteen different professions; some of these are large groups like Physiotherapists and some are much smaller such as Speech and Language Therapists (SLT). Most of the people registered by the HCPC work within their own areas of clinical expertise and defined professional scope of practice. However, an increasing number of registrants are undertaking new or additional roles beyond the traditional scope of practice for the defined profession. These roles are often shared with other medical or health professionals and persons undertaking these roles are often, but not consistently, referred to as Advanced Practitioners. Advanced Practitioners are employed within the NHS across all four countries of the UK and are also employed by private healthcare providers. The roles they undertake vary from the highly specialised (e.g. an advanced podiatrist might specialise in biomechanics) to more general roles with greater professional autonomy and decision-making (e.g. a paramedic working in a GP Practice assessing patients with undifferentiated acute problems). As a result, there is currently no consistency in role title, scope of advanced practice, necessary underpinning education or professional accreditation across the HCPC registered professions. This study was undertaken to explore these issues and seek opinion on the need for additional regulatory measures for persons working at an advanced practice level. NB: For the purposes of this study, advanced practice was considered to encompass all roles, regardless of role title, where the level of practice undertaken was considered to be advanced. Method Three approaches to data collection were undertaken to ensure the differing opinions across all HCPC registered professions, different stakeholders and the four nations of the UK were collected. Data were collected through: 1. A UK wide survey of HCPC registered healthcare professionals; 2. A UK wide survey of organisations delivering AHP & scientific advanced practice education; 3. A series of focus groups and interviews across a range of stakeholder groups. Findings The concept of advanced level practice was not consistently understood or interpreted across the different stakeholder groups. Those participants identifying as working at an advanced practice level undertook a range of activities both within and out with the traditional scope of practice of the registered profession adding a further layer of complexity. Educational support and availability for advanced level practice varied across professional groups and inequity of accessibility and appropriateness of content were raised as concerns. There is no consensus across participant groups on the need for regulation of advanced level practice. Perceived advantages to additional regulation were the consistent and equal educational and employer governance expectations, particularly where multiple professional groups are undertaking the same role, all be it with a differing professional educational foundation and lens. However, while some voices across the participant groups felt regulation was essential to assure practice standards and reduce risk of role title misuse, there was equally a lack of appetite for regulation that inhibited agility to respond to, and reflect, the rapidly changing healthcare environment and evolving scope of advanced level practice. Importantly, no evidence was presented from any participant group that advanced level practice within HCPC regulated professions presents a risk to the public. Conclusion The study data presented in this report reflect the complexity of the concept of advanced practice within the HCPC regulated professions. Much of this is a consequence of the differing speeds of professional role development across healthcare organisations and professional groups, often related to service capacity gaps and locally developed education to support local initiatives. Despite this, there is no clear evidence, based on the findings of this research, that additional regulation of advanced level practice is needed, or desired, to protect the public. However, as the HCPC is one of the few organisations with a UK wide remit, it may have a central role in achieving unification across the 4 nations in relation to the future role expectations, educational standards, and governance of advanced level practice

Renal stone detection using a low kilo-voltage paediatric CT protocol – A porcine phantom study

yesIntroduction: Reducing tube voltage is an effective dose saving method in computed tomography (CT) assuming tube current is not concurrently increased. Recent innovations in scanner technology now enable CT tube voltage reduction to 70 kV thereby increasing opportunities for dose reduction in paediatric patients, but it is unclear if the increased image noise associated with 70 kV impacts on ability to visualise renal stones accurately. The purpose was to assess detectability of nephrolithiasis using a bespoke paediatric phantom and low kV, non-contrast CT and to assess inter-observer agreement. Methods: Forty-two renal stones of different size and chemical composition were inserted into porcine kidneys and positioned in a bespoke, water-filled phantom mimicking a 9-year-old child weighing approximately 33kg. The phantom was scanned using 120 and 70 kV CT protocols, and the detectability of the stones was assessed by three radiologists. Absolute agreement and Fleiss’ kappa regarding detectability were assessed. Results: The mean diameter of renal stones as measured physically was 4.24 mm ranging from 1 to 11 mm. Four stones were missed by at least one observer. One observer had a sensitivity of 93 and 95% at 70 and 120 kV, respectively, while the sensitivity for observers 2 and 3 was 98% at both kV levels. Specificity was 100% across readers and kV levels. Absolute agreement between the readers at 70 kV was 92% (kappa = 0.86) and 98% (kappa = 0.96) at 120 kV indicating a strong agreement at both kV levels. Conclusions: The results suggest that lowering the kV does not affect the detection rate of renal stones and may be a useful dose reduction strategy for assessment of nephrolithiasis in children

Exploring Radio Frequency Techniques for Bone Fracture Detection: A Comprehensive Review of Low Frequency and Microwave Approaches

YesThis comprehensive review paper examines bone fracture detection techniques based on time-domain low-frequency and microwave radiofrequency (RF). Early and accurate diagnosis of bone fractures remains critical in healthcare, as it can significantly improve patient outcomes. This review focuses on the potential of low-frequency and microwave RF methods, particularly their combination and application of time-domain analysis for enhanced fracture detection. We begin by providing an overview of the fundamental concepts of RF techniques and then by examining biological tissues' dielectric properties. We then compare the advantages and limitations of various bone fracture detection techniques, such as low-frequency RF methods, microwave RF methods, ultrasonography, X-ray, and CT scans. The discussion then shifts to hybrid approaches that combine low-frequency and microwave techniques, emphasising the advantages of such combinations in fracture detection. Machine learning techniques, their applications in bone fracture detection, and the role of time-domain analysis in hybrid approaches are also investigated. Finally, we examine the accuracy and reliability of simulated models for bone fracture detection. We discuss recent advancements and future directions, such as novel sensor technologies, improved signal processing techniques, integration with medical imaging modalities, and personalised fracture detection approaches. This review aims to comprehensively understand the landscape and future potential of time-domain analysis in low-frequency and microwave RF techniques for bone fracture detection.EU Horizon Europe H2020-MSCA-RISE-2022-2027 (ID: 101086492) and H2020-MSCA-RISE-2019-2024 (ID 872878), Marie Skłodowska-Curie, Research and Innovation Staff Exchange (RISE), and the financial support from the UK Engineering and Physical Sciences Research Council (EPSRC) under grant EP/ X039366/1

The genetic architecture of the human cerebral cortex

The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal cortical development, supporting the radial unit hypothesis. Loci that affect regional surface area cluster near genes in Wnt signaling pathways, which influence progenitor expansion and areal identity. Variation in cortical structure is genetically correlated with cognitive function, Parkinson's disease, insomnia, depression, neuroticism, and attention deficit hyperactivity disorder
