Knowledge, perceptions, and expectations of Artificial intelligence in radiography practice: A global radiography workforce survey

BACKGROUND

Artificial Intelligence (AI) technologies have already started impacting clinical practice across various settings worldwide, including the radiography profession. This study is aimed at exploring a world-wide view on AI technologies in relation to knowledge, perceptions, and expectations of radiography professionals.

METHODS

An online survey (hosted on Qualtrics) on key AI concepts was open to radiography professionals worldwide (August 1st to December 31st 2020). The survey sought both quantitative and qualitative data on topical issues relating to knowledge, perceptions, and expectations in relation to AI implementation in radiography practice. Data obtained was analysed using the Statistical Package for Social Sciences (SPSS) (v.26) and the six-phase thematic analysis approach.

RESULTS

A total of 314 valid responses were obtained with a fair geographical distribution. Of the respondents, 54.1% (157/290) were from North America and were predominantly clinical practicing radiographers (60.5%, 190/314). Our findings broadly relate to different perceived benefits and misgivings/shortcomings of AI implementation in radiography practice. The benefits relate to enhanced workflows and optimised workstreams while the misgivings/shortcomings revolve around de-skilling and impact on patient-centred care due to over-reliance on advanced technology following AI implementation.

DISCUSSION

Artificial intelligence is a tool but to operate optimally it requires human input and validation. Radiographers working at the interface between technology and the patient are key stakeholders in AI implementation. Lack of training and of transparency of AI tools create a mixed response of radiographers when they discuss their perceived benefits and challenges. It is also possible that their responses are nuanced by different regional and geographical contexts when it comes to AI deployment. Irrespective of geography, there is still a lot to be done about formalised AI training for radiographers worldwide. This is a vital step to ensure safe and effective AI implementation, adoption, and faster integration into clinical practice by healthcare workers including radiographers.

CONCLUSION

Advancement of AI technologies and implementation should be accompanied by proportional training of end-users in radiography and beyond. There are many benefits of AI-enabled radiography workflows and improvement on efficiencies but equally there will be widespread disruption of traditional roles and patient-centred care, which can be managed by a well-educated and well-informed workforce.

Postmenopausal women's adherence to pelvic floor muscle exercises over 2 years

OBJECTIVE

This study aimed to investigate women's adherence patterns to pelvic floor muscle exercises (PFME), their associated factors and within-pattern changes.

METHODS

This was a secondary analysis using data collected from 647 women aged 55 years and older in the USA. Women were randomly assigned to either a 2-h class group or an equivalent content 20-min DVD group to receive PFME complemented with adherence enhancement strategies. Adherence was assessed at 3, 12 and 24 months using three self-reported items matching PFME parameters. The k-mean clustering and multinomial logistic regression were used to investigate adherence patterns and their associated factors, respectively. Descriptive statistics were used for within-pattern changes over time.

RESULTS

Four adherence patterns, A, B, C and D, were identified. Women who displayed optimal adherence to all three aforementioned items, i.e. adherence pattern A, constituted 49.1%, 38.2% and 37.2% of women at 3, 12 and 24 months, respectively. Women with income > US$100,000 were more likely to display adherence pattern A within 12 months. Of women who had adherence pattern A at 3 months, 63.9% and 49.2% continued in this pattern at 12 and 24 months.

CONCLUSIONS

Fewer than half of women displayed adherence pattern A for 2 years. Early optimal adherence predicted women's subsequent optimal adherence.

Energy Flux Densities near the Electron Dissipation Region in Asymmetric Magnetopause Reconnection

Magnetic reconnection is of fundamental importance to plasmas because of its role in releasing and repartitioning stored magnetic energy. Previous results suggest that this energy is predominantly released as ion enthalpy flux along the reconnection outflow. Using Magnetospheric Multiscale data we find the existence of very significant electron energy flux densities in the vicinity of the magnetopause electron dissipation region, orthogonal to the ion energy outflow. These may significantly impact models of electron transport, wave generation, and particle acceleration.

Correlation of Computer Vision System Data with Traditional Methods of Evaluating Pork Color and Marbling on the Ventral Side on the Whole Loin and on Individual Loin Chops

ObjectivesPork quality is a combination of many different attributes, including color, intramuscular fat percentage (IMF), pH, drip loss, and tenderness. Currently, in the pork industry, color and marbling of the whole loins are commonly assessed subjectively by a trained evaluator according to the National Pork Board’s color and marbling standard cards. However, subjective color (SCS) and marbling (SMS) scores can be influenced by lighting and evaluator fatigue. Colorimeters are a common technology that are utilized for measurement of color in the meat industry but have their limitations as they only measure a small portion of the surface and cannot separate lean and fat tissue. Ether extract is commonly used for crude fat determination, but it requires a longer time for analysis and a sample that will be consumed by the process. Computer vision system (CVS) is a technology that has been applied in the food industry and is a non-invasive, efficient, and consistent method. Therefore, the objectives of this study were to compare pork color and marbling measured from the whole loin versus its individual chops and to compare the results from different pork quality measurement methods on the same sample.Materials and MethodsWhole pork loins (n = 1400) were obtained from 6 major pork processing plants, with SCS, SMS, Hunter L, a, and b, and CVS images being collected on the ventral side of the loin in the plant. Samples were vacuum packed, shipped, and stored at 4°C for 14 d. Then whole loins were sliced into chops and the third (A) and 10th (B) rib chops were evaluated for SCS and SMS after a 10 min bloom. After SCS and SMS evaluation, Hunter L, a, and b, and CVS images were collected. The A and B chops were vacuum packaged, shipped, trimmed, freeze dried, and then evaluated for crude fat percentage (CF%) using ether extract method. The CF% of the whole loin was estimated as the average of the A and B chops. From the CVS images, lean and fat pixels were segmented to estimate L*, a*, and b* of the lean tissue and CVS IMF.ResultsA lower L* was found for both CVS and colorimeter when evaluating the whole loin (63.06 & 53.63, respectively) compared to the average of A and B chops (68.65 & 58.10, respectively). However, for SCS, individual chops, on average, were darker than the whole loin (2.88 vs. 2.67, respectively). Of all color measurements, Hunter L had the highest correlation when comparing the whole loin to A and B chops (r = 0.72 and 0.72, respectively). When comparing marbling results of the whole loin to the A and B chops, a moderate correlation was found using both SMS (r = 0.67 and 0.60, respectively) and CVS IMF (r = 0.52 and 0.54, respectively). When comparing methods, CVS L* had a stronger correlation with Hunter L than SCS for the whole loin and A and B chops. (r = 0.40 vs. 0.34, 0.82 vs. 0.47, and 0.84 vs. 0.40, respectively). For IMF, SMS had a stronger correlation with CF% than CVS IMF (r = 0.48 vs. 0.34, 0.62 vs. 0.39, and 0.54 vs. 0.38, respectively).ConclusionThese results show great potential for CVS to be used in evaluating pork quality, specifically color and marbling. Additionally, it is possible to predict individual chop color and marbling based on the ventral side of the loin. Further research should be conducted to look at more technologies that can predict pork quality attributes.

P5497The gender paradox in non-ST-segment elevation acute coronary syndrome: an outdated paradigm or a persistent reality-an analysis of contemporary practice from an integrate health care system

Introduction

Although sex related differences in Non-ST-Segment elevation (NSTEMI) acute coronary syndrome (ACS) have been well delineated in the past, there is a paucity of data from contemporary practice on the evolutions of this paradox and its clinical practice implications.

Purpose

We hypothesized that in the era of guideline driven contemporary practice, and in the setting of an integrated heath care model, gender related differences in care and outcomes would be marginal at best if no altogether absent.

Methods

We utilized data from an integrated health care system to identify 4099 patients with NSTEMI-ACS (1531 women; 2561 men). The patients were stratified by gender and a comparative analysis was performed on guideline directed medical therapy, revascularization strategy and major adverse cardiac events between the two groups.

Results

There were significant difference in pharmacologic treatment, catheter based interventions and surgical revascularizations strategies. Underutilization of guideline directed medical therapy was demonstrated in women specifically vis a vis angiotensin converting enzyme inhibitor (ACE-I) (p=0.0014), statins (p=0.0001), and antiplatelet therapy: clopodigrel (p=0.0004), prasugrel (p=0.0012), and ticagrelor (p=0.03). Additionally, clear differences emerged in percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) options despite similarities in high risk status at index presentation by well validated risk algorithms. Specifically, men were more likely to undergo PCI (p=0.021) and CABG (p<0.001) than women. Finally, women had a greater incidence of bleeding complications (p=0.0003) and stroke (p=0,038).

Conclusions

There were treatment disparities in pharmacologic interventions, catheter based interventions, surgical revascularization access and clinical outcomes among patients with NSTEMI-ACS. The persistence of this gender paradox in contemporary practice and despite increasing education and awareness should potentiate further public policy initiatves as well as reinforce the need for geneder specific guidelines

Are there increased periprocedural complications with the MRI-conditional Medtronic Revo SureScan Pacing System? : A meta-analysis

BACKGROUND

The use of magnetic resonance imaging (MRI)-conditional permanent pacemakers has increased significantly. In this meta-analysis, we examine the safety of MRI-conditional pacing systems in comparison with conventional systems.

METHODS

An electronic search was performed using major databases, including studies that compared the outcomes of interest between patients receiving MRI-conditional pacemakers (MRI group) versus conventional pacemakers (control group).

RESULTS

Six studies (5 retrospective and 1 prospective non-randomised) involving 2,118 adult patients were identified. The MRI-conditional pacemakers, deployed in 969 patients, were all from a single manufacturer (Medtronic Pacing System with 5086 leads). The rate of pacemaker lead dislodgement (atrial and ventricular) was significantly higher in the MRI group (3% vs. 1%, OR 2.47 (95% CI 1.26; 4.83), p = 0.008). The MRI group had a significantly higher rate of pericardial complications (2% vs. 1%, OR 4.23 (95% CI 1.18; 15.10), p = 0.03) and a numerically higher overall complication rate in comparison with the conventional group (6% vs. 3%, OR 2.02 (95% CI 0.88; 4.66), p = 0.10) but this was not statistically significant.

CONCLUSIONS

In this meta-analysis, the rates of pacemaker lead dislodgement and pericardial complications were significantly higher with the Medtronic MRI-conditional pacing system.

Families' experiences of involvement in care planning in mental health services: an integrative literature review

WHAT IS KNOWN ON THE SUBJECT?: Current policy advocates for the participation of family carers in care planning. Caring for a person with a mental illness requires a significant commitment from families to support their relative's recovery. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: The evidence of family involvement in care planning is generally fraught with conflicting experiences related to different requirements between mental health professionals, families and service users. Confidentiality remains contentious at a practice level in terms of information sharing and decision-making. There is a requirement and need for a shared understanding around care planning between families and mental health professionals. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: The provision of written information pertaining to families regarding confidentiality is required at service level. Educational workshops concerning care planning and treatment options should be provided for service users, families and mental health professionals. Further research into effective service-wide strategies that explore with families how their engagement can be positively fostered in mental health services is warranted.

ABSTRACT

Introduction Mental health service policy stipulates that family carers be involved in care planning. Aim To identify families' experiences of care planning involvement in adult mental health services. Method An integrative review where electronic databases and grey literature were searched for papers published between 01 January 2005 and 10 February 2016. Results Fifteen papers met the inclusion criteria. Thematic analysis generated three themes: (1) families' experience of collaboration, (2) families' perceptions of professionals and (3) families' impressions of the care planning process. Collaborative decision-making is not regularly experienced by families with an 'us' and 'them' divide, perpetuated by a lack of communication, confidentiality constraints and a claim of 'insider knowledge' of service users. When involved, families perceive care planning to be uncoordinated and that their lived experiences are not always appreciated. Discussion Families need to be valued, empowered and engaged in care planning and the partnership distance be addressed. Accommodating the views of family, service user and professionals is preferable but not always possible. Our findings suggest that the key element for professionals is to value all 'insider knowledge' where possible. Implications for Practice Services should develop written information on confidentiality for families and facilitate open communication concerning their involvement in care planning.

Burden of illness in systemic lupus erythematosus: results from a UK patient and carer online survey

Objective The objective of this study was to assess the impact of systemic lupus erythematosus (SLE) on patients and carers. Methods Adults with SLE and carers of SLE patients completed a UK-specific online survey covering many aspects of the disease. Surveys were developed in collaboration with an NHS lupus unit and a lupus patient organization. Results A total of 121 patients and 31 carers completed the surveys. Of the 70% of patients initially misdiagnosed with another condition, 59% received treatment for the misdiagnosis. Fatigue was the most debilitating symptom, experienced daily by 79% of patients. The proportion of patients not reporting flares to healthcare providers varied with flare severity: mild flares (43%), moderate flares (15%) and severe flares (5%). Most patients (89%) reported reduced ability to socialize, and 76% had changed employment; of these, 52% stopped working completely. Over one-half (52%) of carers in paid employment missed time from work, and 55% of carers reported a worsened financial status. Most carers (87%) experienced interference with social activities. Conclusion SLE is commonly misdiagnosed and has a considerable impact on the physical, social and financial status of patients and carers. Increased awareness of the disease among healthcare providers and employers of patients and their carers is needed.

Electron-scale measurements of magnetic reconnection in space

Magnetic reconnection is a fundamental physical process in plasmas whereby stored magnetic energy is converted into heat and kinetic energy of charged particles. Reconnection occurs in many astrophysical plasma environments and in laboratory plasmas. Using measurements with very high time resolution, NASA's Magnetospheric Multiscale (MMS) mission has found direct evidence for electron demagnetization and acceleration at sites along the sunward boundary of Earth's magnetosphere where the interplanetary magnetic field reconnects with the terrestrial magnetic field. We have (i) observed the conversion of magnetic energy to particle energy; (ii) measured the electric field and current, which together cause the dissipation of magnetic energy; and (iii) identified the electron population that carries the current as a result of demagnetization and acceleration within the reconnection diffusion/dissipation region.

Mental health service users' experiences of mental health care: an integrative literature review

A number of studies have highlighted issues around the relationship between service users and providers. The recovery model is predominant in mental health as is the recognition of the importance of person-centred practice. The authors completed an in-depth search of the literature to answer the question: What are service users' experiences of the mental health service? Three key themes emerged: acknowledging a mental health problem and seeking help; building relationships through participation in care; and working towards continuity of care. The review adds to the current body of knowledge by providing greater detail into the importance of relationships between service users and providers and how these may impact on the delivery of care in the mental health service. The overarching theme that emerged was the importance of the relationship between the service user and provider as a basis for interaction and support. This review has specific implications for mental health nursing. Despite the recognition made in policy documents for change, issues with stigma, poor attitudes and communication persist. There is a need for a fundamental shift in the provider-service user relationship to facilitate true service-user engagement in their care. The aim of this integrative literature review was to identify mental health service users' experiences of services. The rationale for this review was based on the growing emphasis and requirements for health services to deliver care and support, which recognizes the preferences of individuals. Contemporary models of mental health care strive to promote inclusion and empowerment. This review seeks to add to our current understanding of how service users experience care and support in order to determine to what extent the principles of contemporary models of mental health care are embedded in practice. A robust search of Web of Science, the Cochrane Database, Science Direct, EBSCO host (Academic Search Complete, MEDLINE, CINAHL Plus Full-Text), PsycINFO, PsycARTICLES, Social Sciences Full Text and the United Kingdom and Ireland Reference Centre for data published between 1 January 2008 and 31 December 2012 was completed. The initial search retrieved 272 609 papers. The authors used a staged approach and the application of predetermined inclusion/exclusion criteria, thus the numbers of papers for inclusion were reduced to 34. Data extraction, quality assessment and thematic analysis were completed for the included studies. Satisfaction with the mental health service was moderately good. However, accessing services could be difficult because of a lack of knowledge and the stigma surrounding mental health. Large surveys document moderate satisfaction ratings; however, feelings of fear regarding how services function and the lack of treatment choice remain. The main finding from this review is while people may express satisfaction with mental health services, there are still issues around three main themes: acknowledging a mental health problem and seeking help; building relationship through participation and care; and working towards continuity of care. Elements of the recovery model appear to be lacking in relation to user involvement, empowerment and decision making. There is a need for a fundamental shift in the context of the provider-service user relationship to fully facilitate service users' engagement in their care.

Are we shortchanging frail older people when it comes to the pharmacological treatment of urgency urinary incontinence?

Overactive bladder and urgency incontinence are common and distressing conditions in older people, for which the first-line pharmacological treatment is a bladder antimuscarinic agent. Of these, oxybutynin is often recommended in guidelines, but is associated with a higher incidence of adverse drug effects, and in particular has been suggested to have deleterious cognitive effects. Despite this, guidelines often suggest oxybutynin as first-line treatment, and insurance based healthcare systems often require oxybutynin to be used as a first-line therapy and fail before reimbursement for the cost of newer anticholinergics is authorised. We reviewed the literature of bladder antimuscarinics in older adults, using the headings overactive bladder, urinary frequency, urgency, urge, oxybutynin, antimuscarinic, older, older people, and frail. In general, oxybutynin had a similar efficacy to other anticholinergic drugs, but a higher incidence of adverse drug events, in particular significant yet unnoticed cognitive impairment. We conclude that oxybutynin should not be used in frail older people.
