Physical and biophysical markers of assessment in medical training: A scoping review of the literature.

PURPOSE: Assessment in medical education has changed over time to measure the evolving skills required of current medical practice. Physical and biophysical markers of assessment attempt to use technology to gain insight into medical trainees' knowledge, skills, and attitudes. The authors conducted a scoping review to map the literature on the use of physical and biophysical markers of assessment in medical training. MATERIALS AND METHODS: The authors searched seven databases on 1 August 2022, for publications that utilized physical or biophysical markers in the assessment of medical trainees (medical students, residents, fellows, and synonymous terms used in other countries). Physical or biophysical markers included: heart rate and heart rate variability, visual tracking and attention, pupillometry, hand motion analysis, skin conductivity, salivary cortisol, functional magnetic resonance imaging (fMRI), and functional near-infrared spectroscopy (fNIRS). The authors mapped the relevant literature using Bloom's taxonomy of knowledge, skills, and attitudes and extracted additional data including study design, study environment, and novice vs. expert differentiation from February to June 2023. RESULTS: Of 6,069 unique articles, 443 met inclusion criteria. The majority of studies assessed trainees using heart rate variability (n = 160, 36%) followed by visual attention (n = 143, 32%), hand motion analysis (n = 67, 15%), salivary cortisol (n = 67, 15%), fMRI (n = 29, 7%), skin conductivity (n = 26, 6%), fNIRs (n = 19, 4%), and pupillometry (n = 16, 4%). The majority of studies (n = 167, 38%) analyzed non-technical skills, followed by studies that analyzed technical skills (n = 155, 35%), knowledge (n = 114, 26%), and attitudinal skills (n = 61, 14%). 169 studies (38%) attempted to use physical or biophysical markers to differentiate between novice and expert. CONCLUSION: This review provides a comprehensive description of the current use of physical and biophysical markers in medical education training, including the current technology and skills assessed. Additionally, while physical and biophysical markers have the potential to augment current assessment in medical education, there remains significant gaps in research surrounding reliability, validity, cost, practicality, and educational impact of implementing these markers of assessment.

Bridging public and private health services to best meet the cardiometabolic needs of people with severe mental illness: a retrospective cohort study.

OBJECTIVE: Cardiovascular disease is the leading cause of premature mortality in people with severe mental illness (SMI). Despite this, there lacks consensus regarding the most appropriate platform to monitor and treat cardiometabolic risk factors in this cohort. The current study aims to evaluate the effectiveness of tailored cardiometabolic healthcare in a private, GP-led clinic for people with SMI. METHOD: A total of 63 adults with SMI were referred to a private GP-led cardiometabolic clinic from a neighbouring inner-city mental health service, where they received individualised cardiometabolic healthcare free-of-charge between 2014 and 2020. Paired t test was used to measure change in cardiometabolic data over the course of treatment. Chi-squared and Fisher's Exact tests were used to examine differences in demographic data and client engagement. RESULTS: Over a mean period of 9 months, there was a significant mean reduction of weight (2.1 kg), BMI (0.72 kg/m2) and waist circumference (6 cm). Engagement over a longer period was associated with stable accommodation and improved cardiometabolic outcomes. CONCLUSIONS: Targeted referral for individualised cardiometabolic interventions can lead to clinically significant improvement in cardiometabolic outcomes, providing a cause for therapeutic optimism when approaching physical health in people with SMI.

Optimizing Upper-Tract Imaging for Non-Visible Haematuria.

INTRODUCTION: Non-visible haematuria (NVH) is associated with a small risk of upper-tract urothelial carcinoma (UTUC), though there is little consensus on its investigation, particularly with regard to upper-tract imaging. This study aimed to determine whether the presentation of UTUC can guide investigation of NVH in patients under 60 years old. METHODS: All patients investigated at our one-stop haematuria clinics under a cancer pathway were reviewed during a 5-year period, with all patients undergoing cystoscopy and upper-tract imaging. Retrospective analysis of all UTUC cases from our urological cancer multidisciplinary team meeting database over a 10-year period was also undertaken. RESULTS: 2,129 patients with a median age of 67 years underwent urgent investigation for haematuria between March 2015 and February 2020. 449 cases presented with NVH, of whom 124 (27.6%) were under 60. Out of 21 cases of UTUC, only 2 presented with NVH; both were over the age of 60 years. Factors that independently predicted diagnosis with urinary-tract malignancy were age ≥60 (OR 3.70, p < 0.001), visible haematuria (OR 2.50, p = 0.006), and suspicious cystoscopic findings (OR 58.06, p < 0.001). Review of all 119 UTUC cases over 10 years found 6 cases (5.0%) presenting with NVH, with one (0.8%) also presenting under 60 years. CONCLUSION: Diagnosis with UTUC is rare in patients presenting with NVH under the age of 60 years. Routine use of CTU in this low-risk group is best avoided, with ultrasonography constituting a safer first-line upper-tract imaging modality. Guidelines that risk-stratify NVH patients may be effective in reducing unnecessary investigations.

Margin status and survival outcomes after breast cancer conservation surgery: prospectively registered systematic review and meta-analysis.

OBJECTIVE: To determine if margin involvement is associated with distant recurrence and to determine the required margin to minimise both local recurrence and distant recurrence in early stage invasive breast cancer. DESIGN: Prospectively registered systematic review and meta-analysis of literature. DATA SOURCES: Medline (PubMed), Embase, and Proquest online databases. Unpublished data were sought from study authors. ELIGIBILITY CRITERIA: Eligible studies reported on patients undergoing breast conserving surgery (for stages I-III breast cancer), allowed an estimation of outcomes in relation to margin status, and followed up patients for a minimum of 60 months. Patients with ductal carcinoma in situ only or treated with neoadjuvant chemotherapy or by mastectomy were excluded. Where applicable, margins were categorised as tumour on ink (involved), close margins (no tumour on ink but <2 mm), and negative margins (≥2 mm). RESULTS: 68 studies from 1 January 1980 to 31 December 2021, comprising 112 140 patients with breast cancer, were included. Across all studies, 9.4% (95% confidence interval 6.8% to 12.8%) of patients had involved (tumour on ink) margins and 17.8% (13.0% to 23.9%) had tumour on ink or a close margin. The rate of distant recurrence was 25.4% (14.5% to 40.6%) in patients with tumour on ink, 8.4% (4.4% to 15.5%) in patients with tumour on ink or close, and 7.4% (3.9% to 13.6%) in patients with negative margins. Compared with negative margins, tumour on ink margins were associated with increased distant recurrence (hazard ratio 2.10, 95% confidence interval 1.65 to 2.69, P<0.001) and local recurrence (1.98, 1.66 to 2.36, P<0.001). Close margins were associated with increased distant recurrence (1.38, 1.13 to 1.69, P<0.001) and local recurrence (2.09, 1.39 to 3.13, P<0.001) compared with negative margins, after adjusting for receipt of adjuvant chemotherapy and radiotherapy. In five studies published since 2010, tumour on ink margins were associated with increased distant recurrence (2.41, 1.81 to 3.21, P<0.001) as were tumour on ink and close margins (1.44, 1.22 to 1.71, P<0.001) compared with negative margins. CONCLUSIONS: Involved or close pathological margins after breast conserving surgery for early stage, invasive breast cancer are associated with increased distant recurrence and local recurrence. Surgeons should aim to achieve a minimum clear margin of at least 1 mm. On the basis of current evidence, international guidelines should be revised. SYSTEMATIC REVIEW REGISTRATION: CRD42021232115.

Case for mandatory COVID-19 vaccinations for workers in health and aged care settings: a guide for leaders.

BACKGROUND: This brief paper provides an overview of the analysis in support of mandating COVID-19 vaccinations for all workers in health and aged care settings in Australia. Leaders of health and aged care organisations have a duty of care under work health and safety legislation to eliminate and/or control the risk of transmission of vaccine-preventable disease in their facilities, including COVID-19. METHODS: Key issues that should be considered by healthcare leaders when mandating that all health and aged care workers be vaccinated against COVID-19 were analysed by executives from a large Australian national health and aged care provider and discussed in this paper. RESULTS: This paper summarises the medical/scientific, ethical, legal, work health and safety, workers' compensation and industrial relations considerations when mandating COVID-19 vaccination for healthcare workers. CONCLUSION: Leaders of health and aged care organisations must provide a safe environment and workplace for all those who work for them, as well as for those who receive care or treatment at one of their facilities. It is hoped that this paper will assist leaders of healthcare organisations in making their own decisions during this time.

Does the mineral content of tap water correlate with urinary calculus composition?

The association between the mineral content of drinking water and urolithiasis remains elusive. The aim of this study is to investigate whether the mineral composition of tap water correlates with urinary calculus composition. Patients with calculi that underwent biochemical analysis at two urological centres in the North-West of England between November 2015 and December 2020 were included. Calculus composition was reviewed with respect to patient demographics, serum biochemical variables, and water mineral composition data obtained from the local water supply company using patient postcodes. 1711 urinary tract calculi from 1518 patients, living in 87 water supply zones were included. Water sodium concentration was an independent predictor of mixed calcium oxalate/uric acid calculi (OR 1.157, p < 0.001) and a negative independent predictor of calcium oxalate monohydrate (OR 0.896, p = 0.001) and dihydrate (OR 0.742, p = 0.034) calculi. Moreover, the magnesium-to-calcium ratio of tap water was a negative independent predictor of calcium oxalate monohydrate calculi (OR < 0.001, p = < 0.001), while tap water magnesium concentration inversely correlated with the percentage of calcium oxalate within calculi (rs = - 0.054, p = 0.026). Total water hardness did not independently predict calculus type. Many factors are implicated in the formation of urinary calculi. This study is the first to assess calculus composition in relation to tap water mineral content using postcode data on a case-by-case basis. Though total water hardness did not independently predict calculus composition, the interesting findings relating to water sodium and magnesium concentrations are in need of closer scrutiny in larger scale studies.

The Purpose, Design, and Promise of Medical Education Research Labs.

Medical education researchers are often subject to challenges that include lack of funding, collaborators, study subjects, and departmental support. The construct of a research lab provides a framework that can be employed to overcome these challenges and effectively support the work of medical education researchers; however, labs are relatively uncommon in the medical education field. Using case examples, the authors describe the organization and mission of medical education research labs contrasted with those of larger research team configurations, such as research centers, collaboratives, and networks. They discuss several key elements of education research labs: the importance of lab identity, the signaling effect of a lab designation, required infrastructure, and the training mission of a lab. The need for medical education researchers to be visionary and strategic when designing their labs is emphasized, start-up considerations and the likelihood of support for medical education labs is considered, and the degree to which department leaders should support such labs is questioned.

Clinical parameters of hypervirulent Klebsiella pneumoniae disease and ivermectin treatment in New Zealand sea lion (Phocarctos hookeri) pups.

Hypervirulent Klebsiella pneumoniae infection causes significant mortality of endangered New Zealand sea lion pups at Enderby Island, Auckland Islands. Gross necropsy and histopathology findings are well reported, but little is known about the clinical course of disease in affected pups. To determine factors feasible as clinical screening tools for hypervirulent K. pneumoniae in live pups, 150 pups over two field seasons (2016-18) were recruited shortly after birth for a prospective cohort study. A randomised controlled clinical treatment trial with the anthelmintic ivermectin was conducted concurrently and risk factor data and biological samples were collected approximately fortnightly. Treatment with ivermectin has been demonstrated to reduce the risk of hypervirulent K. pneumoniae mortality in pups, so effects on clinical parameters between the treated and control cohorts were also investigated. A broader sample of pups were monitored for clinical signs to investigate the course of disease in affected pups. Clinical signs, haematology and oral and rectal swabs to detect gastrointestinal carriage of hypervirulent K. pneumoniae were not useful for detection of disease prior to death. Of those pups that died due to hypervirulent K. pneumoniae, only 26.1% (18/69) had any clinical signs prior, likely a reflection of the peracute course of disease. On comparison of haematological parameters between ivermectin-treated and control pups, significantly lower total plasma protein and higher eosinophil counts were seen in control versus treated pups, however standard length as a surrogate for age was a more important influence on parameters overall than ivermectin treatment. This study also highlighted a cohort of pups with severe clinical signs suggestive of hypervirulent K. pneumoniae infection were lost to follow up at the end of the monitored season, which could be contributing to cryptic juvenile mortality.

Effect of resident complement on timeliness of stroke team activation in an academic emergency department.

OBJECTIVES: Investigations of the impact of residents on emergency department (ED) timeliness of care typically focus only on global ED flow metrics. We sought to describe the association between resident complement/supervisory ratios and timeliness of ED care of a specific time-sensitive condition, acute stroke. METHODS: We matched ED stroke patient arrivals at 1 academic stroke center against resident and attending staffing and constructed a Cox proportional hazards model of door-to-activation (DTA) time (ie, ED arrival ["door"] to stroke team activation). We considered multiple predictors, including calculated ratios of residents supervised by each attending physician. RESULTS: Among 462 stroke activation patients in 2014-2015, DTA ranged from 1 to 217 minutes, 72% within 15 minutes. The median number of emergency and off-service residents supervised per attending were 1.7 (interquartile range [IQR], 1.3-2.3) and 0.7 (IQR, 0-1), respectively. A 1-resident increase in off-service residents was associated with a 24% decrease (hazard ratio [HR], 0.76; 95% confidence interval [CI], 0.64-0.90) in the probability of stroke team activation at any given time. An independent 1-resident increase in the number of emergency residents was associated with a 13% increase (HR, 1.13; 95% CI, 1.01-1.25) in timely activation. CONCLUSION: Timeliness of care for acute stroke may be impacted by how academic EDs configure the complement and supervisory structures of residents. Higher supervisory demands imposed by increasing the proportion of rotating off-service residents may be associated with slower stroke recognition and DTA times, but this effect may be offset when more emergency residents are present.

Sexual satisfaction and sexual distress after cancer: The role of body image disruption, self-compassion, sexual pain and relationship satisfaction.

OBJECTIVE: To identify variables that correlate with sexual satisfaction and sexual distress among adult cancer survivors, and how these differ, providing a basis from which approaches to intervention may be identified. This study examined four key variables: body image disruption, self-compassion, relationship satisfaction and sexual pain, previously all linked to sexual quality of life. METHODS: A cross-sectional survey was conducted online, with participants (n = 113) recruited via cancer charities, support groups and sexual counsellors' networks. A multivariate multiple regression analysis was conducted to analyse relationships among variables. RESULTS: In a regression adjusted for age, sex and time since diagnosis, higher sexual distress was significantly associated with higher body image disruption (ß = 0.23; p = 0.024), lower self-compassion (ß = -0.29; p = 0.009) and higher sexual pain (ß = 0.39; p < 0.001); but not relationship satisfaction (ß = -0.08; p = 0.434). Higher sexual satisfaction was significantly associated with higher relationship satisfaction (ß = 0.35; p = 0.002) and lower sexual pain (ß = -0.29; p = 0.005), but not body image disruption (ß = -0.19; p = 0.089), or self-compassion (ß = 0.06; p = 0.614). Sexual pain had a significantly stronger association with sexual distress than sexual satisfaction; F (1, 84) = 18.29, p < 0.001. CONCLUSIONS: Sexual distress and sexual satisfaction are associated with different psycho-social correlates even though both are used as indicators of sexual health. Research should seek to further understand the differences in these two critical markers of sexual health, with these differences likely to highlight the need to match interventions to the nature of the sexual difficulties experienced following cancer treatment.

Do surgical margins matter after mastectomy? A systematic review.

BACKGROUND: No consensus exists regarding adequacy of margins after mastectomy. To determine if pathological margin proximity is associated with local (LR) or distant recurrence after mastectomy for early invasive breast cancer or ductal carcinoma in situ. METHODS: A systematic review of literature published from 1980 to 2019 and meta-analysis was conducted. Unpublished data were sought from authors (PROSPERO (CRD42019127541)). Thirty-four studies comprising 34,833 breast cancer patients were included in the quantitative synthesis. Eligible studies reported on patients undergoing curative mastectomy for cancer allowing estimation of outcomes in relation to margin status/width. The association between pathological margin status and local (LR) and distant recurrence was considered using random effects modelling. PRISMA guidelines were followed. RESULTS: Positive margins were associated with increased LR on multivariable analyses (HR, 2·64, (95%CI 2·01-3·46)) and LR was higher regardless of the distance of tumour from the margin defined as positive. After skin-sparing mastectomy, positive margins were associated with increased LR (HR 3·40, (95%CI 1·9-6·2)). In the 4 studies reporting distant recurrence, patients with involved margins had a higher risk (HR 1·53, (95%CI 1·03-2·25)). CONCLUSIONS: Failure to achieve clear margins after mastectomy may increase the risks of local and distant recurrence. Adequate margin clearance should be recommended to minimize recurrence after mastectomy in National and International Guidelines.

Improving rates of metabolic monitoring on an inpatient psychiatric ward.

OBJECTIVES: Cardiovascular disease is the leading cause of premature death in patients with mental illness. Metabolic syndrome is a cluster of co-occurring cardiovascular risk factors, seen in high frequency in severe mental illness. Despite ease of diagnosis, monitoring is often poor across psychiatric populations. This report details a quality improvement initiative undertaken on an inpatient psychiatric ward to improve rates of metabolic monitoring. METHODS: Four key interventions were developed: (1) A nurse-led intervention, where nurses were upskilled in performing metabolic monitoring, (2) Education was provided to all staff, (3) Introduction of a suite of interventions to improve metabolic risk and (4) Ongoing consumer involvement. A pre-post intervention study design was used to measure effectiveness, with an audit of metabolic monitoring rates performed 12 months after the intervention began. RESULTS: Rates of weight and height monitoring both increased from 46.0% to 69.5% (p=0.0185) and body mass index (BMI) recordings increased from 33% to 63% (p=0.0031). Rates of waist circumference monitoring increased from 44.2% to 65.2% (p=0.0498). Blood pressure (BP) measurements increased from 88.5% to 100% (p=0.0188). Lipid monitoring rates improved from 23% to 69.5% (p=0.001). Rates of glucose monitoring increased from 74% to 82.5% (p=0.8256), although this was not statistically significant. CONCLUSIONS: We found that metabolic monitoring improved following these simple interventions, with a statistically significant increase in measurement rates of weight, BP, height, lipids, BMI and waist circumference (p<0.05). Overall monitoring of glucose also improved, although not to significant levels. The intervention was acceptable to both patients and staff.

Development of a pilot procedural skills training course for preclerkship medical students.

OBJECTIVE: Despite procedural skills being recognized as an important component of medical school education, medical students are not confident in their ability to carry out a range of medical procedures. We conducted an institutional needs assessment and used the results to inform the creation of a procedure-based preclinical elective for first- and second-year students. METHODS: We surveyed second-, third-, and fourth-year medical students at Alpert Medical School as well as select program directors to guide selection of a list of procedures to be taught in the elective. We then created an extracurricular 10-week procedural skills course for preclerkship medical students utilizing a hands-on, flipped classroom practice model.  Volunteer preceptors were recruited from the Department of Emergency Medicine to participate with a student-to-faculty ratio not exceeding 5:1. Knowledge and skill acquisition were assessed using a multiple-choice knowledge exam and 4-station practical exam, respectively. Pre- and post-course online surveys were used to assess self-perceived confidence for all procedures. RESULTS: We implemented our procedural skills training course for first- and second-year medical students in the fall of 2015. Forty-four students applied for the first iteration of the course and 15 students were selected to participate. Fourteen students ultimately completed the elective as well as the subsequent course surveys, multiple-choice exam, and practical exam. Students who participated in the elective had increased levels of self-reported confidence at the conclusion of the elective and performed better on a practical exam and multiple-choice exam compared to students who participated in only the standard curriculum. CONCLUSION: A longitudinal preclerkship procedural course early during medical school is a feasible method of teaching procedural skills to a cohort of learners. A number of adjustments could be made to the course in order to scale up and include a larger cohort of students at our own or another institution.

Prevalence of and Preparedness to Address Inappropriate Sexual Behavior from Patients During Psychiatry Training: a Pilot Study.

OBJECTIVE: Mental health providers experience inappropriate sexual behavior from patients. It is unclear if training programs adequately prepare trainees to respond to such behaviors. Additionally, trainees may not seek support and guidance from supervisors after an incident. This is an exploratory study to document the prevalence of and assess the preparedness of trainees to deal with inappropriate sexual behavior. METHODS: A survey was administered to 58 psychiatry residents and 14 psychology interns at the NYU School of Medicine. A total of 22 questions were asked regarding participants' experiences with inappropriate sexual behavior, including prevalence of, and preparedness during, and support received after the behavior. RESULTS: Of those who completed the survey, 89% of respondents had experienced inappropriate sexual behavior. Seventy percent said they had no training in responding to inappropriate sexual behavior, and 95% wanted more training. A minority of respondents consistently sought support after these events, and of those who did, only 60% of trainees did so with a supervisor. CONCLUSION: Experiences involving inappropriate sexual behavior are prevalent among the mental health trainees surveyed, but most trainees did not feel that they received adequate training in preparation for or supervision after their experiences. Creating training or establishing protocols to respond to inappropriate sexual behavior may help trainees feel more capable and safer. Further studies are needed to understand inappropriate sexual behavior's impact on trainees and patient care, as well as to assess the efficacy of training and protocols developed to manage inappropriate sexual behavior.
