The changing landscape of professional practice in podiatry, lessons to be learned from other professions about the barriers to change – a narrative review

Background: The delivery of healthcare is changing and aligned with this, the podiatry profession continues to change with evidence informed practice and extending roles. As change is now a constant, this gives clinicians the opportunity to take ownership to drive that change forward. In some cases, practitioners and their teams have done so, where others have been reluctant to embrace change. It is not clear to what extent good practice is being shared, whether interventions to bring about change have been successful, or what barriers exist that have prevented change from occurring. The aim of this article is to explore the barriers to changing professional practice and what lessons podiatry can learn from other health care professions. Main body: A literature search was carried out which informed a narrative review of the findings. Eligible papers had to (1) examine the barriers to change strategies, (2) explore knowledge, attitudes and roles during change interventions, (3) explore how the patients/service users contribute to the change process (4) include studies from predominantly primary care in developed countries. Ninety-two papers were included in the final review. Four papers included change interventions involving podiatrists. The barriers influencing change were synthesised into three themes (1) the organisational context, (2) the awareness, knowledge and attitudes of the professional, (3) the patient as a service user and consumer. Conclusions: Minimal evidence exists about the barriers to changing professional practice in podiatry. However, there is substantial literature on barriers and implementation strategies aimed at changing professional practices in other health professions. Change in practice is often resisted at an organisational, professional or service user level. The limited literature about change in podiatry, a rapidly changing healthcare workforce and the wide range of contexts that podiatrists work, highlights the need to improve the ways in which podiatrists can share successful attempts to change practice

Mass Drug Administration and beyond: how can we strengthen health systems to deliver complex interventions to eliminate neglected tropical diseases?

Achieving the 2020 goals for Neglected Tropical Diseases (NTDs) requires scale-up of Mass Drug Administration (MDA) which will require long-term commitment of national and global financing partners, strengthening national capacity and, at the community level, systems to monitor and evaluate activities and impact. For some settings and diseases, MDA is not appropriate and alternative interventions are required. Operational research is necessary to identify how existing MDA networks can deliver this more complex range of interventions equitably. The final stages of the different global programmes to eliminate NTDs require eliminating foci of transmission which are likely to persist in complex and remote rural settings. Operational research is required to identify how current tools and practices might be adapted to locate and eliminate these hard-to-reach foci. Chronic disabilities caused by NTDs will persist after transmission of pathogens ceases. Development and delivery of sustainable services to reduce the NTD-related disability is an urgent public health priority. LSTM and its partners are world leaders in developing and delivering interventions to control vector-borne NTDs and malaria, particularly in hard-to-reach settings in Africa. Our experience, partnerships and research capacity allows us to serve as a hub for developing, supporting, monitoring and evaluating global programmes to eliminate NTDs

A scattering rate approach to the understanding of absorption line broadening in near-infrared AlGaN/GaN quantum wells

There has been much interest in the advancement of III-Nitride growth technology to fabricate AlGaN/GaN heterostructures for intersubband transitions (ISBTs). The large conduction band offset in these structures (up to 2 eV) allows transition energies in the near- to the far-infrared region, which have applications from telecommunications, such as in all-optical switches, to infra-red detectors for sensing and imaging. To date, ISBT electroluminescence has been elusive and absorption measurements remain an important method to verify band structure calculations. The growth quality can be inferred from the absorption spectrum, which will have line broadening with contributions that are both inhomogeneous (large-scale interface roughness, and non-parabolicity) and homogeneous (electron scattering related lifetime broadening). In the present work we calculated the contributions of various homogeneous broadening mechanisms (electron interaction with longitudinal-optical (LO) phonons, acoustic phonons, impurities and alloy disorder) to the full linewidth, and also the contribution of band non-parabolicity, which contributes to the inhomogeneous broadening. Calculations are then compared to the measured absorption spectra of several samples

Early career choices and successful career progression in surgery in the UK: prospective cohort studies

Background: Changes to the structure of medical training worldwide require doctors to decide on their career specialty at an increasingly early stage after graduation. We studied trends in career choices for surgery, and the eventual career destinations, of UK graduates who declared an early preference for surgery. Methods: Postal questionnaires were sent, at regular time intervals after qualification, to all medical qualifiers from all UK medical schools in selected qualification years between 1974 and 2005. They were sent in the first year after qualification, at year three and five years after qualification, and at longer time intervals thereafter. Results: Responses were received from 27 749 of 38 280 doctors (73%) at year one, 23 468 of 33151 (71%) at year three, and 17 689 of 24 870 (71%) at year five. Early career preferences showed that surgery has become more popular over the past two decades. Looking forward from early career choice, 60% of respondents (64% of men, 48% of women) with a first preference for a surgical specialty at year one eventually worked in surgery (p < 0.001 for the male-female comparison). Looking backward from eventual career destinations, 90% of responders working in surgery had originally specified a first choice for a surgical specialty at year one. 'Match' rates between eventual destinations and early choices were much higher for surgery than for other specialties. Considering factors that influenced early specialty choice 'a great deal', comparing aspiring surgeons and aspiring general practitioners (GPs), a significantly higher percentage who chose surgery than general practice specified enthusiasm for the specialty (73% vs. 53%), a particular teacher or department (34% vs. 12%), inclinations before medical school (20% vs. 11%), and future financial prospects (24% vs. 13%); and a lower percentage specified that hours and working conditions had influenced their choice (21% vs. 71%). Women choosing surgery were influenced less than men by their inclinations before medical school or by their future financial prospects. Conclusions: Surgery is a popular specialty choice in the UK. The great majority of doctors who progressed in a surgical career made an early and definitive decision to do so

Pressure dependent electronic properties of MgO polymorphs: A first-principles study of Compton profiles and autocorrelation functions

The first-principles periodic linear combination of atomic orbitals method within the framework of density functional theory implemented in the CRYSTAL06 code has been applied to explore effect of pressure on the Compton profiles and autocorrelation functions of MgO. Calculations are performed for the B1, B2, B3, B4, B8_1 and h-MgO polymorphs of MgO to compute lattice constants and bulk moduli. The isothermal enthalpy calculations predict that B4 to B8_1, h-MgO to B8_1, B3 to B2, B4 to B2 and h-MgO to B2 transitions take place at 2, 9, 37, 42 and 64 GPa respectively. The high pressure transitions B8_1 to B2 and B1 to B2 are found to occur at 340 and 410 GPa respectively. The pressure dependent changes are observed largely in the valence electrons Compton profiles whereas core profiles are almost independent of the pressure in all MgO polymorphs. Increase in pressure results in broadening of the valence Compton profiles. The principal maxima in the second derivative of Compton profiles shifts towards high momentum side in all structures. Reorganization of momentum density in the B1 to B2 structural phase transition is seen in the first and second derivatives before and after the transition pressure. Features of the autocorrelation functions shift towards lower r side with increment in pressure.Comment: 19 pages, 8 figures, accepted for publication in Journal of Materials Scienc

Motile cilia defects in diseases other than primary ciliary dyskinesia:The contemporary diagnostic and research role for transmission electron microscopy

Ultrastructural studies have underpinned the cell biological and clinical investigations of the varied roles of motile cilia in health and disease, with a long history since the 1950s. Recent developments from transmission electron microscopy (TEM; cryo-electron microscopy, electron tomography) have yielded higher resolution and fresh insights into the structure and function of these complex organelles. Microscopy in ciliated organisms, disease models, and in patients with ciliopathy diseases has dramatically expanded our understanding of the ubiquity, multisystem involvement, and importance of cilia in normal human development. Here, we review the importance of motile cilia ultrastructural studies in understanding the basis of diseases other than primary ciliary dyskinesia

Objective The present study aimed to compare a range of cooling methods possibly utilised by occupational workers, focusing on their effect on body temperature, perception and manual dexterity. Methods Ten male participants completed eight trials involving 30 min of seated rest followed by 30 min of cooling or control of no cooling (CON) (34C, 58% relative humidity). The cooling methods utilised were: ice cooling vest (CV0), phase change cooling vest melting at 14C (CV14), evaporative cooling vest (CVEV), arm immersion in 10C water (AI), portable water-perfused suit (WPS), heliox inhalation (HE) and ice slushy ingestion (SL). Immediately before and after cooling, participants were assessed for fine (Purdue pegboard task) and gross (grip and pinch strength) manual dexterity. Rectal and skin temperature, as well as thermal sensation and comfort, were monitored throughout. Results Compared with CON, SL was the only method to reduce rectal temperature (P = 0.012). All externally applied cooling methods reduced skin temperature (P0.05). Conclusion The present study observed that ice ingestion or ice applied to the skin produced the greatest effect on rectal and skin temperature, respectively. AI should not be utilised if workers require subsequent fine manual dexterity. These results will help inform future studies investigating appropriate pre-cooling methods for the occupational worker.This project is financially supported by the US Government through the Technical Support Working Group within the Combating Terrorism Technical Support Office.Published versio

An evaluation of a health status measure and two health utility measures in patients with inflammatory polyarthritis

Background: The ability to measure health and the value of improving or declining health is crucial to the evaluation of health care interventions. Many generic and disease specific health status measures exist for use in patients with rheumatoid arthritis (RA). The Overall Status in Rheumatoid Arthritis (OSRA) measure is a new and simple measure with early evidence of construct validity. Generic health profiles with attached utility weights such as the EuroQol EQ-5D and the SF-6D (calculated from the Medical Outcome Study 36-item short-form health survey) allow the quantification of a patient???s health relative to perfect health and death, and can be used to estimate quality adjusted life years (QALYs). The EQ-5D is extensively used in RA, but has potential limitations. The SF-6D appears to have potential, but needs further evaluation. The aim of this thesis was to assess the validity and responsiveness of the EQ5D, SF-6D and OSRA in UK RA patients, and compare the performance and implications of the use of the EQ-5D and SF-6D.Methods and subjects: Patient data were obtained from three sources; the Steroids in Very Early Arthritis (STIVEA) (n=256) and British Rheumatoid arthritis Outcome Study Group (BROSG) (n=466) randomised controlled trials, and the British Society for Rheumatology Biologics Register (BSRBR) (n=129). The data used included lifestyle and demographic factors, disease activity (DAS28), functional disability (HAQ), X-rays to assess erosive damage, the EQ-5D and the SF-6D. The OSRA was collected only in the BROSG trial. Visual analogue scales (VAS) of pain and fatigue were collected in BROSG and STIVEA. Construct validity was tested by correlating the EQ-5D, SF-6D and OSRA with a range of outcome measures for RA. Responsiveness to change was assessed using minimum important differences (MID), effect size (ES) and standardised response means (SRM), and compared using ratios. EQ-5D profiles placing arthritis patients in utility states ???worse than death??? (negative scores) were described and assessed using linear and logistic regression. The implications of using the EQ-5D and SF-6D in economic evaluation were compared by cost-effectiveness analyses of the BROSG trial.Results: The correlation of the EQ-5D and SF-6D was moderate to high (0.67). Both measures had moderate to high correlations with disease activity, physical function, joint damage and fatigue. The OSRA Activity (OSRA-A) and Damage (OSRA???D) correlated strongly with measures of related aspects of disease. The EQ-5D, SF-6D and OSRA discriminated between known differences in health status across groups defined by social deprivation and disease activity. The EQ-5D MID was 0.04 for improvement and 0.10 for deterioration. The SF-6D MID was 0.04 in both directions. The SF-6D was more responsive to improvement (EQ-5D: SF-6D ES ratio 0.78-0.88) and the EQ-5D more responsive to deterioration (ES ratio 1.14) in health. The OSRA-A was the most sensitive disease specific measure in the BROSG trial, and the OSRA ???D was more responsive than the HAQ. The factors associated with being in a ???worse than death??? health state were male gender, the HAQ, SF-36 mental composite scale, pain VAS, and erythrocyte sedimentation rate (a marker of inflammation). Pain was the predominant factor and was scored at the most extreme level in every worse than death profile. The cost-effectiveness analyses (BROSG trial), found net quality adjusted life years (QALYs) were greater for the EQ-5D (0.07) than the SF-6D (0.05), but had higher variance than the SF-6D. Conclusions: The EQ-5D and SF-6D appear valid and responsive to changes in health in RA, but measure subtly different aspects of health. There are issues with both measures, and cost-effectiveness conclusions of a study could differ according to which measure was used. The EQ-5D may be more likely to demonstrate that an intervention is cost effective than the SF-6D, due to its larger mean change in response to change in health status. The OSRA is valid for use in RA and its responsiveness suggests potential for inclusion in clinical trials
