Assessing the profile and utility of diplomates in occupational medicine.

BACKGROUND: The utility of the occupational medicine diploma in the UK is yet to be explored. The NHS 'Growing Occupational Health (OH) and Wellbeing' programme provides opportunities for diplomates to increase their OH work. AIMS: To assess what proportion of diplomates carry out OH work, the type of work being undertaken, to identify obstacles impeding OH work, to capture their interest in future work opportunities and what additional support they require. METHODS: A link to an online questionnaire was sent to diplomates via several professional bodies; we estimate that 2428 diplomates received this. The survey was open from 24 March to 31 May 2022. RESULTS: Replies were received from 310/2428 (13%) diplomates. Fifty-two per cent of respondents were males and 35% were female. Respondents were diverse in terms of age and geographical region. Main employment settings: 13% primary care, 43% secondary care, 31% private sector, 24% public sector and 20% self-employed. Seventy-two per cent of diplomates had undertaken OH clinical work since completion of their diploma, and 90% of those were undertaking OH clinical work at the time of the survey. Specific obstacles to accessing OH work highlighted included existing workload constraints, lack of employment opportunities with OH providers and lack of time. CONCLUSIONS: Many (126/310; 41%) respondents had considered increasing their OH work in the previous 12 months. Increasing mentorship from senior OH clinicians to diplomates was suggested by 4% of respondents to enhance the utility of diplomates.

Developing and testing a case-management intervention to support the return to work of health care workers with common mental health disorders.

BACKGROUND: To assess the feasibility and acceptability of conducting a trial of the clinical effectiveness and cost-effectiveness of a new case-management intervention to facilitate the return to work of health care workers, on sick leave, having a common mental disorder (CMD). METHODS: A mixed methods feasibility study. RESULTS: Systematic review examined 40 articles and 2 guidelines. Forty-nine National Health Service Occupational Health (OH) providers completed a usual care survey. We trained six OH nurses as case managers and established six recruitment sites. Forty-two out of 1938 staff on sick leave with a CMD were screened for eligibility, and 24 participants were recruited. Out of them, 94% were female. Eleven participants received the intervention and 13 received usual care. Engagement with most intervention components was excellent. Return-to-work self-efficacy improved more in the intervention group than in the usual care group. Qualitative feedback showed the intervention was acceptable. CONCLUSIONS: The intervention was acceptable, feasible and low cost to deliver, but it was not considered feasible to recommend a large-scale effectiveness trial unless an effective method could be devised to improve the early OH referral of staff sick with CMD. Alternatively, the intervention could be trialled as a new stand-alone OH intervention initiated at the time of usual OH referral.

Expanding the strategic and clinical leadership role of accredited specialists.

BACKGROUND: We sought to explore the value and benefits of accredited specialists employed in the National Health Service (NHS), and proposed strategies for expanding their role. AIMS: To explore the core characteristics of accredited specialists and to examine how their skills could be further utilized to enhance occupational health (OH) services. METHODS: Mixed methods comprising a survey and qualitative work. RESULTS: OH survey was completed by 65 of 128 (51%) respondents. Nine accredited specialists and 16 stakeholders contributed qualitative data. Most OH departments were located in acute NHS trusts and additionally provided externally contracted services. We found a large variation in OH staffing and OH services delivered. The COVID pandemic created unprecedented challenges and required expansion in services to meet demand. The majority of respondents described greater recognition and appreciation by others of accredited specialists and OH teams for their specialist contribution during the pandemic. From the qualitative data, we identified two overarching themes. 'Professional credibility has currency' (Theme 1) and 'A visionary future' (Theme 2). A series of sub-themes are described. CONCLUSIONS: Accredited specialists employed in the NHS possess a core set of attributes and capabilities, and are skilful at delivering strong, influential and impactful clinical and strategic leadership across the NHS hierarchy and landscape. The COVID pandemic provided valuable opportunities for them to showcase their specialist clinical and leadership skills. The current wider reorientation of NHS clinical services offers bold new ways to expand their role beyond traditional clinical boundaries.

Exploring the importance of work outcomes in gynaecological patients.

BACKGROUND: There has been increasing evidence that physicians in gynaecology are not routinely enquiring about work during consultations. AIMS: To explore the effect gynaecological conditions can have on work functioning, the importance of work outcomes among patients and whether work considerations are discussed during clinical consultations. METHODS: A cross-sectional survey was administered to employed patients attending a gynaecological clinic at Guy's Hospital. The survey assessed four areas: demographics, gynaecological condition (including self-assessed severity), work status and perceived impact of the condition on work functioning and job satisfaction. Simple descriptive analysis and statistical techniques were used to interpret the data. RESULTS: One hundred and six participants participated (mean age: 37.49 ±â€…9.09). About 95% found it important to be able to work whilst receiving treatment and 82% of patients had reported at least a slight impact on their working ability due to their condition. Of the 31 patients for whom it was their first appointment, 77% said it would be useful to discuss the possible impacts their gynaecological condition could have on their work. About 66% (19/29) of the participants attending a follow-up appointment reported that their doctor had not discussed their work with them. CONCLUSIONS: The symptoms of gynaecological conditions can impact patients' ability to work. There is a lack of useful discussion from doctors about the perceived impact gynaecological conditions can have on a patient's ability to work, despite patients finding it important to be able to remain or return to work.

Assessing the psychosocial impact of stammering on work.

BACKGROUND: Stammering (stuttering) is a speech condition with high heterogeneity, affecting approximately 1% of adults. Research shows it can limit career progression, impact job performance and quality of life. AIMS: To assess the psychosocial impact of stammering among healthcare workers and to develop a new workplace support intervention. METHODS: A cross-sectional questionnaire of healthcare workers who stammer with qualitative work and a survey of occupational health (OH) usual care to assess the need for a workplace intervention. RESULTS: Data from 470 staff questionnaires and 32 OH clinicians were analysed. Eighty-four per cent rated their stammering severity as mild-to-moderate, with the majority reporting adverse impact on job performance and career progression. Most experienced a high degree of anxiety and embarrassment at work, with avoidance behaviours commonplace. Four per cent of respondents sought OH advice for work difficulties. Qualitative data highlighted practical challenges staff experience in the workplace. Sixty-five per cent supported the proposal for a new workplace intervention. We found workplace stress and anxiety were the most common reasons for OH referrals, and we found wide variation in the scope of OH assessments and work adjustments recommended. Most OH respondents reported insufficient clinical knowledge of speech disorders and their impact on work. CONCLUSIONS: Stammering can have a negative impact of workers' job performance and job satisfaction. This can precipitate feelings of stress and anxiety, and can affect self-identity at work. We found wide variation in the provision of OH usual care. The results informed the development of a new workplace intervention.

Factors associated with sickness absence in a large NHS Trust.

BACKGROUND: Sickness absence rates vary widely across a large acute NHS Trust, with the highest rates in some of the largest directorates. AIMS: This study was aimed to identify factors associated with sickness absence in teams and to inform interventions to improve staff health and well-being. METHODS: Using 2018 data from the electronic staff record and NHS Staff Survey, we examined variables associated with cost centre sickness absence rates, perceived abuse and staff engagement scores using multivariable linear regression. RESULTS: Data were available for 9362/15 423 (61%) of staff. Cost centre sickness absence was significantly positively associated with predominance of nursing and midwifery staff (ß = 0.28 [0.012-0.55]) and significantly inversely associated with predominance of medical and dental staff (ß = -0.94 [-1.2 to -0.65]) and proportion white (ß = -1.11 [-1.9 to -0.37]). Cost centre sickness absence was not significantly associated with staff engagement, reported abuse, age or higher headcount. Cost centre staff engagement was significantly positively associated with proportion white (ß = 0.98 [0.42-1.6]). Reported abuse by managers (ß = -13 [-22 to -4.2]) and by colleagues (ß = -24 [-35 to -12]) was significantly inversely associated with proportion white. Reported abuse by colleagues was significantly associated with predominance of medical and dental (ß = 7.6 [2.3-13]) and nursing and midwifery staff (ß = 9.1 [4.4-14]). CONCLUSIONS: These observed associations of sickness absence, staff engagement and perceived abuse with job mix and ethnicity should be further explored. Individual or team-level data, rather than cost centre-level data, might more meaningfully elucidate why sickness absence rates vary between groups of staff.

A self-report questionnaire to detect hand dermatitis in nurses.

BACKGROUND: Hand dermatitis is highly prevalent among nurses due to their frequent exposure to wet work. Providing cost-effective dermatological health surveillance for this occupational group presents a challenge to health service providers. AIMS: To ascertain the predictive value of nurses' self-assessment of whether they had current hand dermatitis using a screening questionnaire when compared with the assessment made by a dermatologist of the nurses' hand photographs. METHODS: We conducted a cross-sectional study comparing the self-report decision made by student and intensive care nurses using a single hand dermatitis screening question with the clinical assessment of their hand photographs made by dermatologists using a standardized photographic guide. RESULTS: We analysed data collected at study baseline (n = 1599). The results showed that the screening question had a high negative predictive value (91%; 95% CI 89-93), but a low positive predictive value (39%; 95% CI 34-45). It demonstrated acceptable accuracy in distinguishing those with and without the disease (area under the receiver operator curve = 0.7) and had a high specificity (86%; 95% CI 84-88) but a sensitivity of only 52% (95% CI 46-59) in identifying hand dermatitis. CONCLUSIONS: We found that nurses were able to accurately self-assess themselves as not having any signs of hand dermatitis. By contrast, they were less able to accurately self-assess positive cases suggesting under-recognition of early disease. We propose that a questionnaire containing a single hand dermatitis screening question should be considered as a tool for screening out clear cases as part of a workplace health surveillance programme for detecting hand dermatitis.

The quality of e-fit notes issued in secondary care.

BACKGROUND: Few data are available on the pattern of use of fit notes issued in secondary care settings. AIMS: To evaluate the pattern and quality of e-fit notes issued in an NHS Trust. METHODS: Anonymized data on patients admitted to Guy's and St Thomas' NHS Foundation Trust (London, UK) who had an e-fit note issued from 1 January to 31 August 2017 were analysed using descriptive statistical methods. Thematic analysis was used to group the free-text comments into distinct categories and themes. RESULTS: A total of 815 fit notes were issued during the study period. A total of 659 (81%) fit notes advised that patients were 'not fit' for work, whilst 156 (19%) advised that they 'may be fit' for work. The specialty with the highest proportion of patients assessed as may be fit was plastic surgery 46/104 (44%), whilst the lowest was ear, nose and throat surgery 0/57 (0%). The majority 151/156 (97%) of fit notes which advised that patients may be fit for work used the tick-box sections on the fit note to recommend work modifications. Of the free-text comments in section 4 of the 'may be fit' e-fit notes issued, 91/114 (80%) were related to the functional ability of patients. CONCLUSIONS: Our study suggests that doctors in secondary care are more willing to use the 'may be fit' option on the fit note than primary care practitioners. Most fit notes, which advised that a patient may be fit for work, suggested workplace modifications.

A behaviour change package to prevent hand dermatitis in nurses working in the National Health Service: results of a cluster randomized controlled trial.

BACKGROUND: Occupational hand dermatitis poses a serious risk for nurses. OBJECTIVES: To evaluate the clinical and cost-effectiveness of a complex intervention in reducing the prevalence of hand dermatitis in nurses METHODS: This was a cluster randomized controlled trial conducted at 35 hospital trusts, health boards or universities in the UK. Participants were (i) first-year student nurses with a history of atopic conditions or (ii) intensive care unit (ICU) nurses. Participants at intervention sites received access to a behavioural change programme plus moisturizing creams. Participants at control sites received usual care. The primary outcome was the change of prevalent dermatitis at follow-up (adjusted for baseline dermatitis) in the intervention vs. the control group. Randomization was blinded to everyone bar the trials unit to ensure allocation concealment. The trial was registered on the ISRCTN registry: ISRCTN53303171. RESULTS: Fourteen sites were allocated to the intervention arm and 21 to the control arm. In total 2040 (69·5%) nurses consented to participate and were included in the intention-to-treat analysis. The baseline questionnaire was completed by 1727 (84·7%) participants. Overall, 789 (91·6%) ICU nurses and 938 (84·0%) student nurses returned completed questionnaires. Of these, 994 (57·6%) had photographs taken at baseline and follow-up (12-15 months). When adjusted for baseline prevalence of dermatitis and follow-up interval, the odds ratios (95% confidence intervals) for hand dermatitis at follow-up in the intervention group relative to the controls were 0·72 (0·33-1·55) and 0·62 (0·35-1·10) for student and ICU nurses, respectively. No harms were reported. CONCLUSIONS: There was insufficient evidence to conclude whether our intervention was effective in reducing hand dermatitis in our populations. Linked Comment: Brans. Br J Dermatol 2020; 183:411-412.

Managing common mental health disorders in healthcare workers.

BACKGROUND: Approximately a quarter of sickness absence in the UK National Health Service (NHS) is attributed to common mental health disorders (CMHDs). This is costly to the NHS and impacts on patient care and staff morale. Little is known about the occupational health (OH) management of NHS staff who take sick leave for CMHDs. AIMS: To explore the current OH management of NHS staff on sick leave for CMHDs. METHODS: We invited providers of NHS OH services identified from the NHS Health at Work Network and Commercial OH Providers Association to complete a survey on the management of employees off work because of CMHDs. Analysis involved descriptive statistics and content analysis. RESULTS: Forty-nine (39%) of the 126 OH departments approached responded. The majority (98%) had an organizational sickness absence policy that included triggers for referral for staff absent with CMHDs. In 63%, referral occurred 8-28 days after the onset of absence; in 92%, the consultation was completed by an OH nurse or OH physician. Content of the first consultation often included assessment of symptoms and medication for CMHDs. Case management and regular reviews were least commonly used despite evidence on their effectiveness in supporting return to work. All providers offered some support for managers of staff with CMHDs. CONCLUSION: Variation existed between providers of NHS OH services in the timing of referrals, use of case management and regular reviews for staff with CMHDs. Our findings suggest that current evidence-based guidance on interventions to improve return to work is not being implemented consistently.

Holographic imaging of electromagnetic fields via electron-light quantum interference.

Holography relies on the interference between a known reference and a signal of interest to reconstruct both the amplitude and the phase of that signal. With electrons, the extension of holography to the ultrafast time domain remains a challenge, although it would yield the highest possible combined spatiotemporal resolution. Here, we show that holograms of local electromagnetic fields can be obtained with combined attosecond/nanometer resolution in an ultrafast transmission electron microscope (UEM). Unlike conventional holography, where signal and reference are spatially separated and then recombined to interfere, our method relies on electromagnetic fields to split an electron wave function in a quantum coherent superposition of different energy states. In the image plane, spatial modulation of the electron energy distribution reflects the phase relation between reference and signal fields. Beyond imaging applications, this approach allows implementing quantum measurements in parallel, providing an efficient and versatile tool for electron quantum optics.

Ultrafast generation and control of an electron vortex beam via chiral plasmonic near fields.

Vortex-carrying matter waves, such as chiral electron beams, are of significant interest in both applied and fundamental science. Continuous-wave electron vortex beams are commonly prepared via passive phase masks imprinting a transverse phase modulation on the electron's wavefunction. Here, we show that femtosecond chiral plasmonic near fields enable the generation and dynamic control on the ultrafast timescale of an electron vortex beam. The vortex structure of the resulting electron wavepacket is probed in both real and reciprocal space using ultrafast transmission electron microscopy. This method offers a high degree of scalability to small length scales and a highly efficient manipulation of the electron vorticity with attosecond precision. Besides the direct implications in the investigation of nanoscale ultrafast processes in which chirality plays a major role, we further discuss the perspectives of using this technique to shape the wavefunction of charged composite particles, such as protons, and how it can be used to probe their internal structure.

Multisite musculoskeletal pain in migrants from the Indian subcontinent to the UK: a cross-sectional survey.

BACKGROUND: Recent findings indicate that wide international variation in the prevalence of disabling regional musculoskeletal pain among working populations is driven by unidentified factors predisposing to pain at multiple anatomical sites. As a step towards identification of those factors, it would be helpful to know whether the prevalence of multisite pain changes when people migrate between countries with differing rates of symptoms; and if so, whether the change is apparent in first generation migrants, and by what age it becomes manifest. METHODS: To address these questions, we analysed data from an earlier interview-based cross-sectional survey, which assessed the prevalence of musculoskeletal pain and risk factors in six groups of workers distinguished by the nature of their work (non-manual or manual) and their country of residence and ethnicity (UK white, UK of Indian subcontinental origin and Indian in India). Prevalence odds ratios (ORs) with 95% confidence intervals (CIs) were estimated by logistic regression. RESULTS: Among 814 participants (response rate 95.4%), 20.6% reported pain at ≥3 anatomical sites. This outcome was much less frequent in Indian manual workers than among white non-manual workers in the UK (adjusted OR 0.06, 95%CI 0.01-0.36), while rates in Indian non-manual workers were intermediate (OR 0.29, 95%CI 0.12-0.72). However, within the UK, there were only small differences between white non-manual workers and the other occupational groups, including those of Indian sub-continental origin. This applied even when analysis was restricted to participants aged 17 to 34 years, and when second and later generation migrants were excluded. CONCLUSIONS: The observed differences in the prevalence of multisite pain seem too large to be explained by healthy worker selection or errors in recall, and there was no indication of bias from differences in understanding of the term, pain. Our findings suggest that whatever drives the higher prevalence of musculoskeletal pain in the UK than India is environmental rather than genetic, affects multiple anatomical sites, begins to act by fairly early in adult life, and has impact soon after people move from India to the UK.

Managers' response to mental health issues among their staff.

BACKGROUND: Many organizations are implementing mental health training for managers to facilitate better communication between managers and employees suffering from mental health problems. Much of this training focuses on improving managers' mental health literacy and reducing stigma. However, it is unclear whether this focus is appropriate or whether other targets, such as improving skills and confidence, should be given greater consideration. AIMS: To test whether knowledge, attitudes and confidence are associated with managers' behavioural responses to mental health issues among their staff. METHODS: Managers from a large Australian fire and rescue service completed a questionnaire addressing their knowledge, attitudes, confidence and behavioural responses when managing employee mental health issues. The relationship was assessed using logistic regression. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. RESULTS: Eighty-five managers responded (response rate 66%). Managers' confidence was the strongest predictor of their behaviour. Managers who felt confident discussing mental health were significantly more likely to make contact with an employee who was suspected to be suffering from a mental illness (OR 15.79, 95% CI 3.03-82.37, P < 0.01) or was on sickness leave for mental health reasons (OR 19.84, 95% CI 2.25-175.15, P < 0.01). Non-stigmatizing attitudes towards mental illness also significantly predicted contact with a staff member off work due to mental health problems (OR 5.22, 95% CI 1.21-22.54, P < 0.05). CONCLUSIONS: Our findings suggest that manager mental health training should focus on building their confidence and reducing stigma in order to have the greatest chance of altering workplace practices.

Attosecond coherent control of free-electron wave functions using semi-infinite light fields.

Light-electron interaction is the seminal ingredient in free-electron lasers and dynamical investigation of matter. Pushing the coherent control of electrons by light to the attosecond timescale and below would enable unprecedented applications in quantum circuits and exploration of electronic motions and nuclear phenomena. Here we demonstrate attosecond coherent manipulation of a free-electron wave function, and show that it can be pushed down to the zeptosecond regime. We make a relativistic single-electron wavepacket interact in free-space with a semi-infinite light field generated by two light pulses reflected from a mirror and delayed by fractions of the optical cycle. The amplitude and phase of the resulting electron-state coherent oscillations are mapped in energy-momentum space via momentum-resolved ultrafast electron spectroscopy. The experimental results are in full agreement with our analytical theory, which predicts access to the zeptosecond timescale by adopting semi-infinite X-ray pulses.

Influences on use of hand moisturizers in nurses.

Background: Nurses are at high risk of hand dermatitis. Regular hand moisturizing can prevent dermatitis, but nurses' use of hand moisturizers is suboptimal. Aims: To establish (i) what beliefs about hand dermatitis and hand moisturizer use are associated with hand moisturizer use by nurses at home and at work and (ii) if hand moisturizer use behaviours in nurses are associated with the prevalence of hand dermatitis. Methods: We used a questionnaire to investigate nurses' knowledge, beliefs and behaviours regarding hand dermatitis and use of hand moisturizers. Results: The response rate was 55/65 (85%). Forty-two (76%) participants agreed that applying hand moisturizers reduced the risk of dermatitis, and 53 (96%) agreed that dermatitis increased the risk of skin carrying pathogenic organisms. Frequent moisturizer application was associated with beliefs that it was part of the nurse's role to apply hand creams, a belief that they had had training in the use of moisturizers and believing that patients approved of them moisturizing their hands. Conclusions: Hand moisturizer use by nurses can be improved by enhancing their beliefs that it is part of their professional role to apply hand cream regularly.

Laser-Induced Skyrmion Writing and Erasing in an Ultrafast Cryo-Lorentz Transmission Electron Microscope.

We demonstrate that light-induced heat pulses of different duration and energy can write Skyrmions in a broad range of temperatures and magnetic field in FeGe. Using a combination of camera-rate and pump-probe cryo-Lorentz transmission electron microscopy, we directly resolve the spatiotemporal evolution of the magnetization ensuing optical excitation. The Skyrmion lattice was found to maintain its structural properties during the laser-induced demagnetization, and its recovery to the initial state happened in the sub-µs to µs range, depending on the cooling rate of the system.

Mixed contact methods to improve response to a postal questionnaire.

BACKGROUND: Postal questionnaires remain an important method of collecting data in trials. However, a high non-response rate can lead to biases, which may undermine the validity of the study. AIMS: To assess a simple method of trying to improve response rates in an occupational health trial evaluating an intervention to prevent hand dermatitis in nurses. METHODS: The trial employed questionnaires at t = 0, t = 1 month and t = 12 months. The t = 1 month questionnaire was posted to study participants (student and intensive care nurses) together with a free postage reply envelope. After 2 weeks, an e-mail was sent to non-responders reinforcing the need for completed questionnaires to be returned. Two weeks later, non-responders were sent another hard copy of the questionnaire, along with an accompanying letter. Six weeks after posting the initial questionnaires, non-responders were sent an SMS text message or were telephoned to remind them to return the questionnaire. RESULTS: The response rates for the 744 student nurses were 8% (no reminder), 27% (after first reminder), 22% (after second reminder) and 27% (after the third reminder), resulting in a response rate of 63%. The response rates for the 959 intensive care nurses were 9% (no reminder), 24% (after first reminder), 24% (after second reminder) and 31% (after third reminder), resulting in a final response rate of 63%. CONCLUSIONS: We found that a series of regular reminders including a third, personalized reminder by SMS text or telephone had a positive impact on non-responders.

Delivery of cognitive behavioural therapy to workers: a systematic review.

BACKGROUND: Cognitive behavioural therapy (CBT) is a key intervention, enabling workers on sick leave with common mental health problems to return to work. It can be delivered by a variety of methods including face-to-face therapy and the Internet. It is not known which is the optimal method of delivery. AIMS: To establish the optimum method of delivering CBT to workers with common mental health problems. METHODS: We undertook a systematic search of the OvidMEDLINE and EMBASE biomedical databases from the start of electronic records to 31 July 2013 for randomized trials comparing one method of delivering CBT with another for treatment of mild-to-moderate depression, anxiety and adjustment disorders. We included publications that assessed at least one of four outcomes: clinical or cost-effectiveness, accessibility and acceptability. A scoping search found no studies in the workplace. We therefore focussed on interventions in the 18-65 year age group. RESULTS: We found six studies comparing methods of delivery of CBT for anxiety disorders but found no trials which compared methods of delivery for mild-to-moderate depression. All delivery methods led to an improvement in anxiety symptoms. Internet-delivered CBT with some input from a therapist was found to be as clinically effective as face-to-face CBT and more cost-effective. CONCLUSIONS: Internet CBT should be made available in workplaces for workers with anxiety disorders as part of a stepped care plan.
