Changes in diagnostic patterns and resource utilisation in Swiss adult ICUs during the first two COVID-19 waves: an exploratory study.

BACKGROUND AND AIM: The coronavirus disease 2019 (COVID-19) outbreak deeply affected intensive care units (ICUs). We aimed to explore the main changes in the distribution and characteristics of Swiss ICU patients during the first two COVID-19 waves and to relate these figures with those of the preceding two years. METHODS: Using the national ICU registry, we conducted an exploratory study to assess the number of ICU admissions in Switzerland and their changes over time, characteristics of the admissions, the length of stay (LOS) and its trend over time, ICU mortality and changes in therapeutic nursing workload and hospital resources in 2020 and compare them with the average figures in 2018 and 2019. RESULTS: After analysing 242,935 patient records from all 84 certified Swiss ICUs, we found a significant decrease in admissions (-9.6%, corresponding to -8005 patients) in 2020 compared to 2018/2019, with an increase in the proportion of men admitted (61.3% vs 59.6%; p <0.001). This reduction occurred in all Swiss regions except Ticino. Planned admissions decreased from 25,020 to 22,021 in 2020 and mainly affected the neurological/neurosurgical (-14.9%), gastrointestinal (-13.9%) and cardiovascular (-9.3%) pathologies. Unplanned admissions due to respiratory diagnoses increased by 1971 (+25.2%), and those of patients with acute respiratory distress syndrome (ARDS) requiring isolation reached 9973 (+109.9%). The LOS increased by 20.8% from 2.55 ± 4.92 days (median 1.05) in 2018/2019 to 3.08 ± 5.87 days (median 1.11 days; p <0.001), resulting in an additional 19,753 inpatient days. The nine equivalents of nursing manpower use score (NEMS) of the first nursing shift (21.6 ± 9.0 vs 20.8 ± 9.4; p <0.001), the total NEMS per patient (251.0 ± 526.8 vs 198.9 ± 413.8; p <0.01) and mortality (5.7% vs 4.7%; p <0.001) increased in 2020. The number of ICU beds increased from 979 to 1012 (+3.4%), as did the number of beds equipped with mechanical ventilators (from 773 to 821; +6.2%). CONCLUSIONS: Based on a comprehensive national data set, our report describes the profound changes triggered by COVID-19 over one year in Swiss ICUs. We observed an overall decrease in admissions and a shift in admission types, with fewer planned hospitalisations, suggesting the loss of approximately 3000 elective interventions. We found a substantial increase in unplanned admissions due to respiratory diagnoses, a doubling of ARDS cases requiring isolation, an increase in ICU LOS associated with substantial nationwide growth in ICU days, an augmented need for life-sustaining therapies and specific therapeutic resources and worse outcomes.

Exploring Medical Career Choice to Better Inform Swiss Physician Workforce Planning: Protocol for a National Cohort Study.

BACKGROUND: A medical student's career choice directly influences the physician workforce shortage and the misdistribution of resources. First, individual and contextual factors related to career choice have been evaluated separately, but their interaction over time is unclear. Second, actual career choice, reasons for this choice, and the influence of national political strategies are currently unknown in Switzerland. OBJECTIVE: The overall objective of this study is to better understand the process of Swiss medical students' career choice and to predict this choice. Our specific aims will be to examine the predominately static (ie, sociodemographic and personality traits) and predominately dynamic (ie, learning context perceptions, anxiety state, motivation, and motives for career choice) variables that predict the career choice of Swiss medical school students, as well as their interaction, and to examine the evolution of Swiss medical students' career choice and their ultimate career path, including an international comparison with French medical students. METHODS: The Swiss Medical Career Choice study is a national, multi-institution, and longitudinal study in which all medical students at all medical schools in Switzerland are eligible to participate. Data will be collected over 4 years for 4 cohorts of medical students using questionnaires in years 4 and 6. We will perform a follow-up during postgraduate training year 2 for medical graduates between 2018 and 2022. We will compare the different Swiss medical schools and a French medical school (the University of Strasbourg Faculty of Medicine). We will also examine the effect of new medical master's programs in terms of career choice and location of practice. For aim 2, in collaboration with the Swiss Institute for Medical Education, we will implement a national career choice tracking system and identify the final career choice of 2 cohorts of medical students who graduated from 4 Swiss medical schools from 2010 to 2012. We will also develop a model to predict their final career choice. Data analysis will be conducted using inferential statistics, and machine learning approaches will be used to refine the predictive model. RESULTS: This study was funded by the Swiss National Science Foundation in January 2023. Recruitment began in May 2023. Data analysis will begin after the completion of the first cohort data collection. CONCLUSIONS: Our research will inform national stakeholders and medical schools on the prediction of students' future career choice and on key aspects of physician workforce planning. We will identify targeted actions that may be implemented during medical school and may ultimately influence career choice and encourage the correct number of physicians in the right specialties to fulfill the needs of currently underserved regions.

Formative assessments during COVID-19 pandemic: an observational study on performance and experiences of medical students.

Background: Because of COVID-19, the 2020 written medical examinations were replaced by mandatory formative online assessments. This study aimed to determine students' performance, self-assessment of performance, and perception about the switch from a summative to a formative approach. Methods: Medical students from year 2 to 5 (n=648) were included. They could repeat each test once or twice. They rated their performance after each attempt and were then given their score. Detailed feedback was given at the end of the session. An online survey determined medical students' perception about the reorganization of education. Two items concerned the switch from summative to formative assessments Results: Formative assessments involved 2385 examinees totaling 3197 attempts. Among examinees, 30.8% made at least 2 attempts. Scores increased significantly at the second attempt (median 9.4, IQR 10.8), and duration decreased (median -31.0, IQR 48.0). More than half of examinees (54.6%) underestimated their score, female students more often than male. Low performers overestimated, while high performers underestimated their scores. Students approved of the switch to formative assessments. Stress was lessened but motivation for learning decreased. Conclusions: Medical students' better scores at a second attempt support a benefit of detailed feedback, learning time and re-test opportunity on performance. Decreased learning motivation and a minority of students repeating the formative assessments point to the positive influence of summative assessment on learning.

A gender biased hidden curriculum of clinical vignettes in undergraduate medical training.

OBJECTIVES: Medical education relies extensively on clinical vignettes, yet little attention has been given to what hidden curriculum they might convey. Our research aimed to identify whether the clinical vignettes used in pre-graduate medical education transmit gender stereotypes or gender biases. METHODS: We conducted a mixed quantitative and qualitative analysis of gender-related characteristics currently existing in clinical vignettes used for pre-graduate teaching and evaluation at the Geneva Faculty of Medicine. RESULTS: 2359 vignettes were identified, of which 955 met inclusion criteria. Patients' professions and family caregiver roles showed a strongly gendered distribution, as did the healthcare professions where male physicians and female nurses were the norm. Qualitative results identified widespread stereotyped gender roles and gender expression. CONCLUSION: Our study reveals that the clinical vignettes used in education and evaluation materials in pre-graduate medical education in Geneva convey a gender-biased hidden curriculum, which could negatively impact patient care and undermine equal opportunity for men and women. PRACTICE IMPLICATIONS: Active revision of the content and the form of clinical vignettes used in undergraduate medical education is needed using a gender lens. Based on rare gender neutral or gender transformative examples from our study, we propose guidelines for writing non-gender-biased vignettes.

Do students' personality traits change during medical training? A longitudinal cohort study.

Many medical schools incorporate assessments of personal characteristics, including personality traits, in their selection process. However, little is known about whether changes in personality traits during medical training affect the predictive validity of personality assessments. The present study addressed this issue by examining the stability of personality traits and their predictive validity over a 6-year medical training course. Participants were two cohorts of Swiss medical students (N = 272, 72% of students admitted to Year 2) from whom we collected demographic data, Swiss medical studies aptitude test (EMS) scores, Big Five personality traits scores measured at three times and scores on the multiple-choice and objective structured clinical examination parts of the final medical examination. Our findings indicated that personality traits had medium-to-high rank-order stability (r > .60 over 3 years and r > .50 over 6 years). Mean-level changes were moderate for agreeableness (d = + 0.72) and small for neuroticism and conscientiousness (d = -0.29, d = -0.25, respectively). Individual reliable change indices ranged from 4.5% for openness to 23.8% for neuroticism. The predictive validity was similar to that of the first three years of follow-up. To the best of our knowledge, this is the first study to investigate changes in personality across undergraduate curriculum. Medical students' personality traits were mostly stable across medical school and retain their predictive validity. Consequently, this study supports the use of tools measuring constructs underlying personality traits in selection. In addition, this study confirms that examination formats could favor students with certain personality traits.

Patients' perceptions of conflicting information on chronic medications: a prospective survey in Switzerland.

OBJECTIVE: The number of patients with chronic diseases and subsequent visits to various healthcare professionals has been rising over the past decades, exposing patients to potential risks of receiving conflicting medication information. This study aims to investigate the prevalence of conflicting information on medications perceived by chronic patients in Switzerland and to understand its impact on patients' medication self-management and navigation in the healthcare system. PARTICIPANTS: This cross-sectional study included adult patients taking at least one prescribed medication for at least 6 months, who had visited at least two physicians in the past 3 months. MAIN OUTCOME MEASURES: Data on patients' perceptions of conflicting information were collected in person through a 17-item questionnaire available on paper and electronically with four domains: (1) whether the patient had perceived any conflicting information, (2) categories of conflicting information, (3) impact and (4) sources involved in the conflicting information. RESULTS: Of the 405 included patients, 47% perceived conflicting information related to one or more medication topics including indication, schedule, dosage, risk, severity or duration of side effects. Patients who perceived conflicting information were prescribed more drugs than those perceiving no conflicting information (p<0.01). Consequently, 65% of the participants modified their navigation of the healthcare system and 34% reported medication non-adherence. General practitioners (82%), specialist physicians (74%) and pharmacists (49%) were the healthcare professionals most often involved in conflicting information. Experience with the medication, its package insert and significant others were more frequently involved in conflicting information than internet or social media. CONCLUSION: Nearly half the patients in our study perceived conflicting information in the outpatient healthcare system, which can decrease medication effectiveness and pose safety issues. This issue is widely overlooked and unaddressed. Consistency of information among healthcare providers in partnership with patients should be reinforced through guidelines and new models of interprofessional care.

The pedagogical value of near-peer feedback in online OSCEs.

PURPOSE OF THE ARTICLE: During the Covid-19 pandemic, formative OSCE were transformed into online OSCE, and senior students (near peers) substituted experienced clinical teachers. The aims of the study were to evaluate quality of the feedbacks given by near peers during online OSCEs and explore the experience of near-peer feedback from both learner's and near peer's perspectives. MATERIALS AND METHODS: All 2nd year medical students (n = 158) attended an online OSCE under the supervision of twelve senior medical students. Outcome measures were 1) students' perception of the quality of the feedback through an online survey (Likert 1-5); 2) objective assessment of the quality of the feedback focusing on both the process and the content using a feedback scale (Likert 1-5); 3) experience of near peer feedback in two different focus groups. RESULTS: One hundred six medical students answered the questionnaire and had their feedback session videotaped. The mean perceived overall quality of senior students' overall feedback was 4.75 SD 0.52. They especially valued self-evaluation (mean 4.80 SD 0.67), balanced feedback (mean 4.93 SD 0.29) and provision of simulated patient's feedback (mean 4.97 SD 0.17). The overall objective assessment of the feedback quality was 3.73 SD 0.38: highly scored skills were subjectivity (mean 3.95 SD 1.12) and taking into account student's self-evaluation (mean 3.71 (SD 0.87). Senior students mainly addressed history taking issues (mean items 3.53 SD 2.37) and communication skills (mean items 4.89 SD 2.43) during feedback. Participants reported that near peer feedback was less stressful and more tailored to learning needs- challenges for senior students included to remain objective and to provide negative feedback. CONCLUSION: Increased involvement of near peers in teaching activities is strongly supported for formative OSCE and should be implemented in parallel even if experience teachers are again involved in such teaching activities. However, it requires training not only on feedback skills but also on the specific content of the formative OSCE.

Dissemination of patient blood management practices in Swiss intensive care units: a cross-sectional survey.

BACKGROUND: Patient blood management (PBM) promotes the routine detection and treatment of anaemia before surgery, optimising the management of bleeding disorders, thus minimising iatrogenic blood loss and pre-empting allogeneic blood utilisation. PBM programmes have expanded from the elective surgical setting to nonsurgical patients, including those in intensive care units (ICUs), but their dissemination in a whole country is unknown. METHODS: We performed a cross-sectional, anonymous survey (10 October 2018 to 13 March 2019) of all ordinary medical members of the Swiss Society of Intensive Care Medicine and the registered ICU nurses from the 77 certified adult Swiss ICUs. We analysed PBM-related interventions adopted in Swiss ICUs and related them to the spread of PBM in Swiss hospitals. We explored blood test ordering policies, blood-sparing strategies and red blood cell-related transfusion practices in ICUs. RESULTS: A total of 115 medical doctors and 624 nurses (response rates 27% and 30%, respectively) completed the surveys. Hospitals had implemented a PBM programme according to 42% of physicians, more commonly in Switzerland's German-speaking regions (Odds Ratio [OR] 3.39, 95% confidence interval [CI] 1.23-9.35; p = 0.018) and in hospitals with more than 500 beds (OR 3.91, 95% CI 1.48-10.4; p = 0.006). The PBM programmes targeted the detection and correction of anaemia before surgery (79%), minimising perioperative blood loss (94%) and optimising anaemia tolerance (98%). Laboratory tests were ordered in 70.4% by the intensivist during morning rounds; the nurses performed arterial blood gas analyses autonomously in 48.4%. Blood-sparing techniques were used by only 42.1% of nurses (263 of 624, missing: 6) and 47.0% of physicians (54 of 115). Approximately 60% of respondents used an ICU-specific transfusion guideline. The reported haemoglobin threshold for the nonbleeding ICU population was 70 g/l and, therefore, was at the lower limit of current guidelines. CONCLUSIONS: Based on this survey, the estimated proportion of the intensivists working in hospitals with a PBM initiative is 42%, with significant variability between regions and hospitals of various sizes. The risk of iatrogenic anaemia is relevant due to liberal blood sample collection practices and the underuse of blood-sparing techniques. The reported transfusion threshold suggests excellent adherence to current international ICU-specific transfusion guidelines.

Medical students' perceptions and coping strategies during the first wave of the COVID-19 pandemic: studies, clinical implication, and professional identity.

BACKGROUND: The unfolding of the COVID-19 pandemic during spring 2020 has disrupted medical education worldwide. The University of Geneva decided to shift on-site classwork to online learning; many exams were transformed from summative to formative evaluations and most clinical activities were suspended. We aimed to investigate the perceived impact of those adaptations by the students at the Faculty of Medicine. METHODS: We sent an online self-administered survey to medical students from years 2 to 6 of the University of Geneva, three months after the beginning of the pandemic. The survey explored students' main activities during the first three months of the pandemic, the impact of the crisis on their personal life, on their training and on their professional identity, the level of stress they experienced and which coping strategies they developed. The survey consisted of open-ended and closed questions and was administered in French. RESULTS: A total of 58.8% of students responded (n = 467) and were homogeneously distributed across gender. At the time of the survey, two thirds of the participants were involved in COVID-19-related activities; 72.5% voluntarily participated, mainly fueled by a desire to help and feel useful. Many participants (58.8%) reported a feeling of isolation encountered since the start of the pandemic. Main coping strategies reported were physical activity and increased telecommunications with their loved ones. Most students described a negative impact of the imposed restrictions on their training, reporting decreased motivation and concentration in an unusual or distraction-prone study environment at home and missing interactions with peers and teachers. Students recruited to help at the hospital in the context of increasing staff needs reported a positive impact due to the enriched clinical exposure. Perceived stress levels were manageable across the surveyed population. If changed, the crisis had a largely positive impact on students' professional identity; most highlighted the importance of the health care profession for society and confirmed their career choice. CONCLUSION: Through this comprehensive picture, our study describes the perceived impact of the pandemic on University of Geneva medical students, their training and their professional identity three months after the start of the pandemic. These results allowed us to gain valuable insight that reinforced the relevance of assessing the evolution of the situation in the long run and the importance of developing institutional support tools for medical students throughout their studies.

French translation and validation of the interprofessional facilitation scale for simulation.

This study aimed to translate the Interprofessional Facilitation Scale in French and validate its use for interprofessional simulation training. Experts translated the items into French and then back translated them into English. Data used for the validation were collected from interprofessional simulation trainings. Experts and observers found the scale's content validity was suitable. A principal component analysis was conducted. The Kaiser-Meyer-Olkin test value was 0.88 and two factors were identified, that explained 59.9% of the variance. They were labeled: (a) Opportunity of Interprofessional Learning and (b) Psychological Safety. The Cronbach's alpha measure of internal consistency was 0.91. The learning simulation environment explained the structure of the scale. This study provides evidence that the French version of Interprofessional Facilitation Scale can be used in the context of interprofessional simulation training.

Assessing communication skills during OSCE: need for integrated psychometric approaches.

BACKGROUND: Physicians' communication skills (CS) are known to significantly affect the quality of health care. Communication skills training programs are part of most undergraduate medical curricula and are usually assessed in Objective Structured Clinical Examinations (OSCE) throughout the curriculum. The adoption of reliable measurement instruments is thus essential to evaluate such skills. METHODS: Using Exploratory Factor Analysis (EFA), Multi-Group Confirmatory Factor Analysis (MGCFA) and Item Response Theory analysis (IRT) the current retrospective study tested the factorial validity and reliability of a four-item global rating scale developed by Hodges and McIlroy to measure CS among 296 third- and fourth-year medical students at the Faculty of Medicine in Geneva, Switzerland, during OSCEs. RESULTS: EFA results at each station showed good reliability scores. However, measurement invariance assessments through MGCFA across different stations (i.e., same students undergoing six or three stations) and across different groups of stations (i.e., different students undergoing groups of six or three stations) were not satisfactory, failing to meet the minimum requirements to establish measurement invariance and thus possibly affecting reliable comparisons between students' communication scores across stations. IRT revealed that the four communication items provided overlapping information focusing especially on high levels of the communication spectrum. CONCLUSIONS: Using this four-item set in its current form it may be difficult to adequately differentiate between students who are poor in CS from those who perform better. Future directions in best-practices to assess CS among medical students in the context of OSCE may thus focus on (1) training examiners so to obtain scores that are more coherent across stations; and (2) evaluating items in terms of their ability to cover a wider spectrum of medical students' CS. In this respect, IRT can prove to be very useful for the continuous evaluation of CS measurement instruments in performance-based assessments.

Severity-Adjusted ICU Mortality Only Tells Half the Truth-The Impact of Treatment Limitation in a Nationwide Database.

OBJECTIVES: The influence of different forms of treatment limitation on mortality rate in the ICU is not known despite the common use of the latter as a quality indicator. The aim of the present study was to assess the prevalence of treatment limitation and its influence on ICU mortality rate. Primary outcomes were prevalence of treatment limitation and its influence on severity-adjusted ICU mortality rate. Secondary outcomes included the association of limitation with age, sex, type of admission, diagnostic group, treatment intensity, and length of ICU stay. DESIGN: Retrospective, observational study. SETTING: All Swiss adult ICUs. INTERVENTIONS: None. PATIENTS: A total of 166,764 patients were admitted to an ICU in 2016 and 2017. Of these, 9139 were excluded because of readmission or invalid coding. MEASUREMENTS AND MAIN RESULTS: Of 157,625 ICU patients, 20,916 (13.3%) had a fully defined treatment limitation. Among this group, treatment limitation was defined upon ICU admission in 12,854 (61%), the decision to limit treatment was based on the patient's advance directives in 9,951 (48%), and in 15,341 (73%), there was a decision to deliberately withhold certain treatment modalities. The mortality odds ratio for the group with a treatment limitation, considering relevant cofactors, was 18.1 (95% CI 16.8-19.4). CONCLUSIONS: Every seventh patient in a Swiss ICU has some kind of treatment limitation, and this most probably affects the severity-adjusted mortality rate. Thus, mortality data as a quality indicator or benchmark in intensive care can only meaningfully be interpreted if existence, grade, cause, and time of treatment limitation are taken into account.

"Evaluation of a best practice approach to assess undergraduate clinical skills in Paediatrics".

BACKGROUND: The Objective Structured Clinical Examination (OSCE) has been used in pediatrics since the 1980s. Its main drawback is that large numbers of children are needed to make up for the fatigue factor inherent in prolonged testing periods. Also, examinations mainly include children between 7 and 16 years old. We describe the summative examination used in our institution to evaluate medical students' clinical competencies in pediatrics with realistic available resources and for a wider age-range. We also evaluated different factors known to influence medical students' performances. METHODS: This retrospective, descriptive, observational study evaluated the 740 distinct pediatric examination results of fourth-year medical students over 5 years. Their summative examination combined two different assessment methods: a structured real-patient examination (SRPE) using standardized assessment grids for the most frequent pediatric diagnoses, and a computer-based written examination (CBWE). RESULTS: Our approach defined an appropriate setting for some key elements of the educational objectives of pediatrics training, such as balancing the child-parent-pediatrician triangle and the ability to interact with pediatric patients, from newborns to 16-year-old adolescents, in a child-friendly fashion in realistic scenarios. SRPE scores showed no associations with students' degrees of exposure to specific lecture topics, vignettes, or bedside teaching. The impacts of clinical setting, topic, and individual examiners on SRPE scores was quite limited. Setting explained 1.6%, topic explained 4.5%, and examiner explained 4.7% of the overall variability in SRPE scores. CONCLUSIONS: By combining two different assessment methods, we were able to provide a best-practice approach for assessing clinical skills in Pediatrics over a wide range of real patients.

Comparison of long-menu and single-best-answer multiple choice questions in computer-based summative assessments: a randomised controlled trial.

BACKGROUND: Little is known regarding the psychometric properties of computerized long-menu formats in comparison to classic formats. We compared single-best-answer (Type A) and long-menu formats using identical question stems during the computer-based, summative, intermediate clinical-clerkship exams for nine disciplines. METHODS: In this randomised sequential trial, we assigned the examinees for every summative exam to either the Type A or long-menu format (four different experimental questions, otherwise identical). The primary outcome was the power of discrimination. The study was carried out at the Faculty of Medicine, University of Geneva, Switzerland, and included all the students enrolled for the exams that were part of the study. Examinees were surveyed about the long-menu format at the end of the trial. RESULTS: The trial was stopped for futility (p = 0.7948) after 22 exams including 88 experimental items. The long-menu format had a similar discriminatory power but was more difficult than the Type A format (71.45% vs 77.80%; p = 0.0001). Over half of the options (54.4%) chosen by the examinees in long-menu formats were not proposed as distractors in the Type A formats. Most examinees agreed that their reasoning strategy was different. CONCLUSIONS: In a non-selected population of examinees taking summative exams, long-menu questions have the same discriminatory power as classic Type A questions, but they are slightly more difficult. They are perceived to be closer to real practice, which could have a positive educational impact. We would recommend their use in the final years of the curriculum, within realistic key-feature problems, to assess clinical reasoning and patient management skills.

A prospective observational study of the main features of nocturnal leg cramps in primary care.

OBJECTIVE: There are few data available regarding the characteristics of nocturnal leg cramps in primary care. However, this condition is particularly common among older adults and often causes sleep disturbances, which can seriously affect quality of life. We aimed to investigate the main characteristics of nocturnal leg cramps occurring over a two-week period in patients visiting primary care physicians. METHODS: This prospective observational study was conducted in western Switzerland from January 2015 until June 2016. Twenty primary care physicians were asked to recruit up to 20 consecutive patients over the age of 50 who had suffered from cramps in the previous three months. Patients completed a daily log during a two-week period, reporting the number and duration (in minutes) of their cramps. They also reported the severity of the cramps and their level of cramp-related sleep disturbance on a scale from 0 to 10. Crude and adjusted associations between the number of cramps and patient characteristics were computed using a generalised mixed effects model (Poisson). RESULTS: Of 550 consecutive patients, 233 agreed to be contacted for participation. Of these, 129 signed the consent to participation form and all completed the questionnaire and the daily log (men: 67%; mean age: 71 years; follow-up rate: 100%). Overall, 41% of patients were suffering from hypertension, 20% from dyslipidaemia, 19% from sleep disturbances and depression, and 6% from diabetes. Half the patients reported having already used a treatment against nocturnal leg cramps in the past, and 25% were currently using magnesium. Most of them also used medication for other health problems (mean number 3.7 per patient; psychotropic drugs: 36%). Patients had a median of two cramps per week, which were generally mild (median rating of 0.7 on a 10-point scale) and short (median: 0.4 min), leading to mild sleep disturbances (median rating of 0.8 on a 10-point scale). Multivariate analysis showed that older age and previous cramp treatment were associated with more cramps per day, while the use of magnesium and/or psychotropic drugs was associated with fewer cramps per day. CONCLUSIONS: Although nocturnal leg cramps are common among older patients in primary care, the disease burden of nocturnal leg cramps only appears to be severe in a minority of patients.

A novel method to assess data quality in large medical registries and databases.

BACKGROUND: There is no gold standard to assess data quality in large medical registries. Data auditing may be impeded by data protection regulations. OBJECTIVE: To explore the applicability and usefulness of funnel plots as a novel tool for data quality control in critical care registries. METHOD: The Swiss ICU-Registry from all 77 certified adult Swiss ICUs (2014 and 2015) was subjected to quality assessment (completeness/accuracy). For the analysis of accuracy, a list of logical rules and cross-checks was developed. Type and number of errors (true coding errors or implausible data) were calculated for each ICU, along with noticeable error rates (>mean + 3 SD in the variable's summary measure, or >99.8% CI in the respective funnel-plot). RESULTS: We investigated 164 415 patient records with 31 items each (37 items: trauma diagnosis). Data completeness was excellent; trauma was the only incomplete item in 1495 of 9871 records (0.1%, 0.0%-0.6% [median, IQR]). In 15 572 patients records (9.5%), we found 3121 coding errors and 31 265 implausible situations; the latter primarily due to non-specific information on patients' provenance/diagnosis or supposed incoherence between diagnosis and treatments. Together, the error rate was 7.6% (5.9%-11%; median, IQR). CONCLUSIONS: The Swiss ICU-Registry is almost complete and data quality seems to be adequate. We propose funnel plots as suitable, easy to implement instrument to assist in quality assurance of such a registry. Based on our analysis, specific feedback to ICUs with special-cause variation is possible and may promote such ICUs to improve the quality of their data.

What factors influence the use of electronic health records during the first 10 minutes of the clinical encounter?

PURPOSE: The use of electronic health records (EHRs) by physicians during the consultation is common and can be problematic. Factors influencing the use of EHRs during clinical encounters include physician and patient characteristics, consultation type as well as spatial organization of the room and type of EHR template. Their relative importance is however not well known. This study aimed to explore to what extent several physician, patient and consultation factors were associated with EHR use during the first 10 minutes of primary care consultations. METHODS: We examined EHR use of 17 residents in 142 videotaped consultations at the Primary Care Division of the Geneva University Hospitals, Switzerland. We conducted univariable and multivariable analyses with patient, physician and consultation variables to predict EHR use: sex and age of the patient; physician's sex, age, postgraduate experience and EHR-use self-perception; and language, type of consultation (new/follow-up) and content of the consultation using the Roter interaction analysis system (RIAS), the main variable being the percentage of utterances in relation to EHR use during the first 10 minutes. RESULTS: Male physicians (residents) and those with less clinical experience and conducting a new consultation or addressing biomedical content were positively correlated with EHR use (+5.3% for male physicians, P=0.101; +0.6% per year of experience, P=0.021; +6.0% for new consultation, P=0.097; +0.4% per 1% of biomedical content increase; P=0.018). CONCLUSION: Only a small number of physician, patient and consultation factors appear to have an impact on the use of EHR during primary care consultations, and this impact remains modest. Given the influence of EHR use on physician-patient relationship, further research should explore what other factors are implicated in EHR use and whether they can be changed or improved.

Effects of increased participation on veteran running performance.

Contrary to elite performance that is approaching an asymptote, recent analyses suggested a trend for improvement in veterans. This might be attributable to a disproportionate increase in older age-group participation. We extracted 26 years (1987-2012) of men's results of a running event in Switzerland, "La Course de l'Escalade" (7.25 km). We investigated trends in performance by five-year age-groups, taking the 10, 20, 30, and 50 fastest in each group, and then the 1st, 5th, and 10th percentiles. Taking the 10, 20, 30 or 50 fastest runners there was a trend for improvement ranging from 0.07 to 0.22 min·year-1 (p < .0001; 95% CI -0.083 to -0.049 and p < .0001; 95% CI -0.250 to -0.196 respectively) in the elder age-groups. Taking the 1st, 5th, and 10th percentiles there were no trends for improvement, and actual deteriorations up to 0.13 (p < .0001; 95% CI +0.119 to +0.138) min·year-1. Mixed-effect models with repeated measures for runners, confirmed a global deteriorating trend with an estimate of +0.11 min·year-1 (p < .0001; 95% CI +0.107 to +0.116). The results suggest that increases in performance in older runners arise from modifications of sampling from a growing population.
