Change in gait speed and adverse outcomes in patients with idiopathic pulmonary fibrosis: A prospective cohort study.

BACKGROUND AND OBJECTIVE: Gait speed is associated with survival in individuals with idiopathic pulmonary fibrosis (IPF). The extent to which four-metre gait speed (4MGS) decline predicts adverse outcome in IPF remains unclear. We aimed to examine longitudinal 4MGS change and identify a cut-point associated with adverse outcome. METHODS: In a prospective cohort study, we recruited 132 individuals newly diagnosed with IPF and measured 4MGS change over 6 months. Death/first hospitalization at 6 months were composite outcome events. Complete data (paired 4MGS plus index event) were available in 85 participants; missing 4MGS data were addressed using multiple imputation. Receiver-Operating Curve plots identified a 4MGS change cut-point. Cox proportional-hazard regression assessed the relationship between 4MGS change and time to event. RESULTS: 4MGS declined over 6 months (mean [95% CI] change: -0.05 [-0.09 to -0.01] m/s; p = 0.02). A decline of 0.07 m/s or more in 4MGS over 6 months had better discrimination for the index event than change in 6-minute walk distance, forced vital capacity, Composite Physiologic Index or Gender Age Physiology index. Kaplan-Meier curves demonstrated a significant difference in time to event between 4MGS groups (substantial decline: >-0.07 m/s versus minor decline/improvers: ≤-0.07 m/s; p = 0.007). Those with substantial decline had an increased risk of hospitalization/death (adjusted hazard ratio [95% CI] 4.61 [1.23-15.83]). Similar results were observed in multiple imputation analysis. CONCLUSION: In newly diagnosed IPF, a substantial 4MGS decline over 6 months is associated with shorter time to hospitalization/death at 6 months. 4MGS change has potential as a surrogate endpoint for interventions aimed at modifying hospitalization/death.

Gender Matters: Understanding Transitions in Surgical Education.

Introduction: Diverse transitions are elemental to medical career trajectories. The effective navigation of such transitions influences a sense of belonging and wellbeing, positive relationships, and good engagement and attainment within new contexts. Using Multiple and Multidimensional Transitions (MMT) theory as an analytical lens, this paper aims to answer the research question: "What gendered transitions do female surgeons experience, and how do these gendered transitions impact them?" Methods: We conducted a qualitative study drawing on narrative inquiry, with face-to-face and online semi-structured interviews with 29 female surgeons across nine surgical specialities in Ireland and Scotland. This paper is part of a larger study including male surgeons, other colleagues and patients of female surgeons. The female surgeons in this paper were purposively sampled using maximum variation sampling across several levels (consultants, trainees and middle-grade doctors), as well as six who had transitioned out of surgery. Framework analysis was employed to interrogate the interview data. Results: Five overarching types of transitions were identified across surgical education but only three of these transitions-work, culture and health-were primarily experienced by female surgeons (not male surgeons so were considered gendered), thereby impacting social, academic, and psychological domains. The remaining two types of transition-education and geography-were seemingly experienced equally by female and male surgeons, so are beyond the scope of this paper focused on female surgeons' gendered experiences. Conclusion: This novel qualitative study drawing on MMT theory illustrates how multiple gendered transitions interact and impact female surgeons across the surgical education continuum. Aligned with MMT theory, family members and others are also purportedly affected by female surgeons' transitions. Healthcare educators, leaders and policymakers need to better understand gendered transitions and their impacts to improve support for female surgical trainees on their educational journeys.

Pulmonary Rehabilitation in Idiopathic Pulmonary Fibrosis and COPD: A Propensity-Matched Real-World Study.

BACKGROUND: The adherence to and clinical efficacy of pulmonary rehabilitation in idiopathic pulmonary fibrosis (IPF), particularly in comparison with COPD, remains uncertain. The objectives of this real-world study were to compare the responses of patients with IPF with a matched group of patients with COPD undergoing the same supervised, outpatient pulmonary rehabilitation program and to determine whether pulmonary rehabilitation is associated with survival in IPF. RESEARCH QUESTION: Do people with IPF improve to the same extent with pulmonary rehabilitation as a matched group of individuals with COPD, and are noncompletion of or nonresponse to pulmonary rehabilitation, or both, associated with 1-year all-cause mortality in IPF? STUDY DESIGN AND METHODS: Using propensity score matching, 163 patients with IPF were matched 1:1 with a control group of 163 patients with COPD referred for pulmonary rehabilitation. We compared between-group pulmonary rehabilitation completion rates and response. Survival status in the IPF cohort was recorded over 1 year after pulmonary rehabilitation discharge. Cox proportional hazards regression explored the association between pulmonary rehabilitation status and all-cause mortality. RESULTS: Similar pulmonary rehabilitation completion rates (IPF, 69%; COPD, 63%; P = .24) and improvements in exercise response were observed in both groups with no significant mean between-group differences in incremental shuttle walk test (ISWT) change (mean, 2 m [95% CI, -18 to 22 m]). Pulmonary rehabilitation noncompletion (hazard ratio [HR], 5.62 [95% CI, 2.24-14.08]) and nonresponse (HR, 3.91 [95% CI, 1.54-9.93]) were associated independently with increased 1-year all-cause mortality in IPF. INTERPRETATION: This real-word study demonstrated that patients with IPF have similar completion rates and magnitude of response to pulmonary rehabilitation compared with a matched group of patients with COPD. In IPF, noncompletion of and nonresponse to pulmonary rehabilitation were associated with increased all-cause mortality. These data reinforce the benefits of pulmonary rehabilitation in patients with IPF.

Chronic Obstructive Pulmonary Disease and Breathlessness in Older Workers Predict Economic Inactivity. A Prospective Cohort Study.

Rationale: There is an aspiration to retain increasing numbers of older workers in employment, and strategies to achieve this need to make provision for the increasing prevalence of chronic diseases with age. There is a consistent body of cross-sectional evidence that suggests that patients with chronic obstructive pulmonary disease are more likely to have adverse employment outcomes.Objectives: We report the findings of the first longitudinal study of this issue.Methods: We recruited full-time employed men and women in their 50s and followed them for a period of 18 months; we examined, after adjustment for potential confounders, the associations between breathlessness and airway obstruction at baseline and loss of employment in the intervening period.Measurements and Main Results: Among participants responding to the follow-up questionnaire (1,656 of 1,773 [93%]), the majority (78.5%) continued in full-time employment, but 10.6% were in part-time employment and 10.9% were no longer in paid employment. The adjusted risk of loss of employment was significantly increased for those with moderate or severe chronic obstructive pulmonary disease (risk ratio, 2.89; 95% confidence interval, 1.80-4.65) or breathlessness (risk ratio, 3.07; 95% confidence interval, 2.16-4.37) at baseline. There was no evident modification by sex or by manual/nonmanual work.Conclusions: Airway obstruction and breathlessness are independently associated with premature loss from the workforce in older workers; these observations provide strong support to the available cross-sectional evidence and suggest that interventions to help those with chronic obstructive pulmonary disease who wish to remain in work need to be tested.

A cognitive forcing tool to mitigate cognitive bias - a randomised control trial.

BACKGROUND: Cognitive bias is an important source of diagnostic error yet is a challenging area to understand and teach. Our aim was to determine whether a cognitive forcing tool can reduce the rates of error in clinical decision making. A secondary objective was to understand the process by which this effect might occur. METHODS: We hypothesised that using a cognitive forcing tool would reduce diagnostic error rates. To test this hypothesis, a novel online case-based approach was used to conduct a single blinded randomized clinical trial conducted from January 2017 to September 2018. In addition, a qualitative series of "think aloud" interviews were conducted with 20 doctors from a UK teaching hospital in 2018. The primary outcome was the diagnostic error rate when solving bias inducing clinical vignettes. A volunteer sample of medical professionals from across the UK, Republic of Ireland and North America. They ranged in seniority from medical student to Attending Physician. RESULTS: Seventy six participants were included in the study. The data showed doctors of all grades routinely made errors related to cognitive bias. There was no difference in error rates between groups (mean 2.8 cases correct in intervention vs 3.1 in control group, 95% CI -0.94 - 0.45 P = 0.49). The qualitative protocol revealed that the cognitive forcing strategy was well received and a produced a subjectively positive impact on doctors' accuracy and thoughtfulness in clinical cases. CONCLUSIONS: The quantitative data failed to show an improvement in accuracy despite a positive qualitative experience. There is insufficient evidence to recommend this tool in clinical practice, however the qualitative data suggests such an approach has some merit and face validity to users.

Assisted conception and the risk of CHD: a case-control study.

Epidemiological studies suggest a higher prevalence of congenital malformations in children conceived through assisted reproductive technologies. There are a few studies that address CHD specifically and most have examined data from registries. We examined the relationship between CHD and assisted conception using data collected in a specialist paediatric cardiac service in the United Kingdom. Between April, 2010 and July, 2011, the parents of children attending paediatric cardiology clinics at the Royal Brompton Hospital, London, were invited to complete a questionnaire that enquired about the nature of their child's conception, the route for their original referral, and a number of potential confounding exposures. "Cases" were defined as children diagnosed with one or more carefully defined CHDs and "controls" as those with normal hearts. Of 894 new attendees with complete data, half of them were cases (n=410, 45.9%). The overall prevalence of assisted conception was 5.4% (n=44). Logistic regression analysis demonstrated a non-significant increase in the crude odds for the use of assisted reproduction (odds ratio 1.21, 95% confidence interval 0.66-2.22) in this group. After adjustment for gestation, parity, year of birth, and maternal age, the odds ratio reduced (odds ratio 0.95, 95% confidence interval 0.48-1.88). Increased rates of assisted conception were observed in a number of CHD subgroups, although no significant differences were found. These findings do not suggest an overall association between CHD and assisted reproduction in this population.

What's in a name? Word inflation, punctuation, abbreviation and cloud formation.

The title of a journal paper offers a crucial portal into any scientific field. It determines whether interested readers locate the paper and whether others have enough interest sparked to lead them to read the abstract. This article looks at authored journal paper titles in Medical Education over its first 50 years (n = 6357) of publication and Medical Teacher over its first 35 years of publication, revealing both trends in areas of interest and how those interests are worded. Word clouds per decade showed a shift from teaching to learning and from examination to assessment, and new foci on learning, patients, research and feedback in both journals. The average length of title in Medical Education peeked in the 2000s, dropping to 70 characters in the 2010s, with no titles being longer than 140 characters (the length of a tweet) in this last decade. Abbreviations were used sparingly. The use of humorous titles, although not common, has increased in recent years. The use of the colon showed a marked increase in the 1980s, dropping a little in the 2000s but resurging in the 2010s. Titles posed as a question increased steadily, appearing to plateau in the 2000s at 11%. The use of humour and questions suggests that the authors of these articles are submitting papers to be selected by the human rather than just the virtual eye. We also hypothesise that the use of humour may indicate a maturation of medical education as a subject.

Translating evidence-based guidelines to improve feedback practices: the interACT case study.

BACKGROUND: There has been a substantial body of research examining feedback practices, yet the assessment and feedback landscape in higher education is described as 'stubbornly resistant to change'. The aim of this paper is to present a case study demonstrating how an entire programme's assessment and feedback practices were re-engineered and evaluated in line with evidence from the literature in the interACT (Interaction and Collaboration via Technology) project. METHODS: Informed by action research the project conducted two cycles of planning, action, evaluation and reflection. Four key pedagogical principles informed the re-design of the assessment and feedback practices. Evaluation activities included document analysis, interviews with staff (n = 10) and students (n = 7), and student questionnaires (n = 54). Descriptive statistics were used to analyse the questionnaire data. Framework thematic analysis was used to develop themes across the interview data. RESULTS: InterACT was reported by students and staff to promote self-evaluation, engagement with feedback and feedback dialogue. Streamlining the process after the first cycle of action research was crucial for improving engagement of students and staff. The interACT process of promoting self-evaluation, reflection on feedback, feedback dialogue and longitudinal perspectives of feedback has clear benefits and should be transferable to other contexts. CONCLUSIONS: InterACT has involved comprehensive re-engineering of the assessment and feedback processes using educational principles to guide the design taking into account stakeholder perspectives. These principles and the strategies to enact them should be transferable to other contexts.

Gait speed and readmission following hospitalisation for acute exacerbations of COPD: a prospective study.

BACKGROUND: Hospitalisation for acute exacerbations of COPD is associated with high risk of readmission. However, no tool has been validated to stratify patients at discharge for risk of readmission. AIM: To evaluate the ability of the 4 m gait speed (4MGS), a surrogate marker of frailty, to predict risk of future readmission in hospitalised patients with an acute exacerbation of COPD (AECOPD). METHODS: 213 patients hospitalised with an AECOPD were recruited prospectively. 4MGS was measured on day of discharge. Logistic regression models were used to assess the association between 4MGS and readmission at 90 days after discharge. RESULTS: Baseline characteristics of the cohort: 52% men; mean age 72 years; median FEV1 35%predicted. Mean (SD) 4MGS at hospital discharge was 0.61 (0.26) ms(-1). Significant increased rates of all-cause readmission at 90 days were seen across quartiles of decreasing 4MGS (Q4 fastest: 11.5%; Q3: 20.4%; Q2: 30.2%; Q1 slowest: 48.2%; p trend<0.001). Compared with Q4, those in the slowest 4MGS quartile had unadjusted ORs (95% CIs) for 90-day readmission of 7.12 (2.61 to 19.44) for the whole cohort and 11.56 (3.08 to 43.35) in those aged 65 or over. A multivariate model incorporating 4MGS, Charlson Index, hospital admission in past year, FEV1%predicted and number of exacerbations in past year in those aged 65 or over predicted 90-day readmission with a C-statistic of 0.86. CONCLUSIONS: The 4MGS, a surrogate marker of physical frailty, independently predicts the risk of readmission in older patients hospitalised for acute exacerbation of COPD. TRIAL REGISTRATION NUMBER: NCT01507415.

Breaking bad news in amyotrophic lateral sclerosis: the need for medical education.

The manner in which physicians deliver difficult diagnoses is an area of discontent for patients with amyotrophic lateral sclerosis (ALS). The American Academy of Neurology's Practice Parameter for care of the ALS Patient recommended teaching and evaluating strategies for disclosing the diagnosis (10). Our objective was to examine residents' ability in and perceptions of communicating the diagnosis of ALS. Twenty-two resident physicians were videotaped and rated by two ALS neurologists as they delivered an ALS diagnosis to a standardized patient (SP) during an objective structured clinical examination (OSCE). Residents self-rated immediately after the OSCE, again after viewing their videotape, and completed a survey regarding the OSCE and delivering difficult diagnoses. OSCE performance was suboptimal, particularly for communication skills and empathy. The two examiners' scores correlated except for the empathy subscore. Residents' self-assessments did not align with the examiners' scores either before or after watching their videotape. The survey uncovered residents' apprehension and dissatisfaction with their training in diagnosis delivery. The results highlight a need for resident education in delivering an ALS diagnosis. The lack of correlation between residents' and examiners' scoring requires further study. Evaluation of empathy is particularly challenging. Residents agreed that OSCE participation was worthwhile.

Welding, longitudinal lung function decline and chronic respiratory symptoms: a systematic review of cohort studies.

While the acute respiratory risks of welding are well characterised, more chronic effects, including those on lung function, are less clear. We carried out a systematic review of published longitudinal studies of lung function decline in welders. Original cohort studies documenting two or more sequential measurements of lung function were reviewed. Meta-analysis was carried out on studies with suitable data on forced expiratory volume in 1 s (FEV1). Seven studies were included; their quality (measured on the Newcastle-Ottawa scale) was good, although exposure assessment was limited and the studies showed significant heterogeneity. Five had data suitable for meta-analysis; the pooled estimate of the difference in FEV1 decline between welders and nonwelders was -9.0 mL · year(-1) (95% CI -22.5-4.5; p=0.193). The pooled estimates of difference in annual FEV1 decline between welders and referents who smoked was -13.7 mL · year(-1) (95% CI -33.6-6.3; p=0.179). For welders and referents who did not smoke the estimated difference was -3.8 mL · year(-1) (95% CI -20.2-12.6; p=0.650). Symptom prevalence data were mainly narrative; smoking appeared to have the greatest effect on symptom evolution. Collectively, available longitudinal data on decline of lung function in welders and respiratory symptoms suggest a greater effect in those who smoke, supporting a focus on smoking cessation as well as control of fume exposure in this trade. Further prospective studies are required to confirm these findings.

How we encourage faculty development.

Most clinicians enjoy teaching medical students, but many have had little training as clinical teachers. The General Medical Council (GMC) in 'Good Medical Practice' states 'if you are involved in teaching you must develop the skills, attitudes and practices of a competent teacher' (GMC 2006). Mclean et al.'s (2008) AMEE guide on faculty development outlines practice points for those responsible for developing their faculty's educational skills. In this article, we look at one health region, Tayside in East Scotland, where the University of Dundee, NHS Education for Scotland (NES) and NHS Tayside are collaborating to implement these practice points. This combined approach has proved to be effective in progressing staff development and recruiting additional clinical colleagues to develop their teaching role.
