Cognitive bias in professional hand hygiene and feedback: A national online-survey on overconfidence in Germany.

To evaluate learning motivation barriers in infection control and feedback competences, we conducted a national online survey in Germany. Among 767 healthcare workers, overconfidence effects could be detected independent from age, gender, profession, education, and hospital-size. The identified effects may impair learning motivation relevant for supervisors and educators in infection control.

Development of a checklist for evaluating psychiatric reports.

BACKGROUND: Performing a psychiatric interview and documenting the recorded findings in the form of a brief psychiatric report is one of the main learning goals in the psychiatric curriculum for medical students. However, observing and assessing students' reports is time consuming and there are no objective assessment tools at hand. Thus, we applied an integrative approach for designing a checklist that evaluates clinical performance, as a tool for the assessment of a psychiatric report. METHODS: A systematic review of the literature yielded no objective instrument for assessing the quality of written reports of psychiatric interviews. We used a 4-step mixed-methods approach to design a checklist as an assessment tool for psychiatric reports: 1. Development of a draft checklist, using literature research and focus group interviews; 2. Pilot testing and subsequent group discussion about modifications resulting from the pilot testing; 3. Creating a scoring system; 4. Testing for interrater-reliability, internal consistency and validity. RESULTS: The final checklist consisted of 36 items with a Cronbach's alpha of 0.833. Selectivity of items ranged between 0.080 and 0.796. After rater-training, an interrater-reliability of 0.96 (ICC) was achieved. CONCLUSIONS: Our approach, which integrated published evidence and the knowledge of domain experts, resulted in a reliable and valid checklist. It offers an objective instrument to measure the ability to document psychiatric interviews. It facilitates a transparent assessment of students' learning goals with the goal of structural alignment of learning goals and assessment. We discuss ways it may additionally be used to measure the ability to perform a psychiatric interview and supplement other assessment formats.

Overconfidence in infection control proficiency.

BACKGROUND: Infection control partially depends on hygiene and communication skills. Unfortunately, motivation for continuous training is lower than desired. Many health care providers (HCPs) do not recognize the need for training but express this need for others. This is attributable to heuristic errors, such as the overconfidence effect. The aim of this study was to quantify the flawed self-assessment in infection-control. METHODS: In this cross-sectional multicenter study, 255 HCPs of different specialties participated in the 29-item, 5-point Likert scale questionnaire, assessing perceived proficiency in hand hygiene and communication skills for both themselves and others (colleagues, trainees, and supervisors of their own specialty and HCPs of others). RESULTS: 222 of 255 surveys could be analyzed. Respondents rated themselves to be better trained in handhygiene (P < .001) than trainees, colleagues, and supervisors; the same was seen for feedback skills (P < .001). HCPs of other specialties were consistently rated worse in all aspects (P < .001). CONCLUSION: Results show an overplacement effect in infection prevention skills. The belief of being well educated creates a subjective conviction that no further education in hand hygiene is needed. Thus, HCPs may face motivation barriers that require specialized programs to overcome these beliefs.

Gender differences in psychosocial outcomes of psychotherapy trial in patients with depression and coronary artery disease.

INTRODUCTION: The biological and psychosocial risk profile differs between women and men with coronary artery disease (CAD). Depressive symptoms and Vital Exhaustion (VE) predict an unfavourable course of CAD. The secondary analysis of the SPIRR-CAD trial offered the possibility to examine gender as exposure variable of the clinical and psychological situation at baseline and in a variety of psychosocial measures as outcomes. METHODS: In this trial, 450 men (78.9%) and 120 women (21.1%) with CAD (age ≤ 75 y), with mild to moderate depression (scoring ≥8 on the HADS), were randomized to usual care with or without a stepwise psychotherapy intervention. Beside clinical measures exhaustion and other indicators of depressive symptoms were collected at baseline and 18-month follow up. RESULTS: Men had more signs and symptoms of heart disease at baseline, whereas women had higher psychosocial burden (e.g. negative affect). Women were more likely to live alone, had lower educational levels and employment rates and higher levels of depression and exhaustion. The psychotherapy intervention differed as a function of gender: In women, VE decreased from 29.4 ±â€¯8.1 to 22.1 ±â€¯11.7 in the intervention group (IG) and from 29.2 ±â€¯8.2 to 25.1 ±â€¯11.3 in the control group (CG). In men VE decreased from 23.3 + -10.8 to 21.2 ±â€¯9.7 in the IG and from 23.6 ±â€¯10.7 to 19.3 ±â€¯11.3 in the CG (time x intervention x gender; F = 4.97; p = .026). DISCUSSION: Women had a higher psychosocial burden than men. VE compared to other rating instruments of depressive symptoms suggested a stronger response to the intervention in women. VE may help to understand gender differences in psychotherapeutic treatment studies of CAD. ISRCTN: 76240576; clinicaltrials.gov.

Does quantity ensure quality? Standardized OSCE-stations for outcome-oriented evaluation of practical skills at different medical faculties.

BACKGROUND: Practical skills are often assessed using Objective Structured Clinical Skill Exams (OSCE). Nevertheless, in Germany, interchange and agreement between different medical faculties or a general agreement on the minimum standard for passing is lacking. METHODS: We developed standardized OSCE-stations for assessing structured clinical examination of knee and shoulder joint with identical checklists and evaluation standards. These were implemented into the OSCE-course at five different medical faculties. Learning objectives for passing the stations were agreed beforehand. At each faculty, one reference examiner scored independently of the local examiner. Outcome of the students at the standardized station was compared between faculties and correlated to their total outcome at the OSCE, to their results at the Part One of the National Medical Licensing Examination as a reference test during medical studies and to their previous amount of lessons in examining joints. RESULTS: Comparing the results of the reference examiner, outcome at the station differed significantly between some of the participating medical faculties. Depending on the faculty, mean total results at the knee-examination-station differed from 64.4% to 77.9% and at the shoulder-examination-station from 62.6% to 79.2%. Differences were seen in knowledge-based items and also in competencies like communication and professional manner. There was a weak correlation between outcome at the joint-examination-OSCE-station and Part One of the National Medical Licensing Examination, and a modest correlation between outcome at the joint-examination-station and total OSCE-result. Correlation to the previous amount of lessons in examining joint was also weak. CONCLUSION: Although addressing approved learning objectives, different outcomes were achieved when testing a clinical skill at different medical faculties with a standardized OSCE-station. Results can be used as a tool for evaluating lessons, training and curricula at the different sites. Nevertheless, this study shows the importance of information exchange and agreement upon certain benchmarks and evaluation standards when assessing practical skills.

Examiner effect on the objective structured clinical exam - a study at five medical schools.

BACKGROUND: The Objective Structured Clinical Examination (OSCE) is increasingly used at medical schools to assess practical competencies. To compare the outcomes of students at different medical schools, we introduced standardized OSCE stations with identical checklists. METHODS: We investigated examiner bias at standardized OSCE stations for knee- and shoulder-joint examinations, which were implemented into the surgical OSCE at five different medical schools. The checklists for the assessment consisted of part A for knowledge and performance of the skill and part B for communication and interaction with the patient. At each medical faculty, one reference examiner also scored independently to the local examiner. The scores from both examiners were compared and analysed for inter-rater reliability and correlation with the level of clinical experience. Possible gender bias was also evaluated. RESULTS: In part A of the checklist, local examiners graded students higher compared to the reference examiner; in part B of the checklist, there was no trend to the findings. The inter-rater reliability was weak, and the scoring correlated only weakly with the examiner's level of experience. Female examiners rated generally higher, but male examiners scored significantly higher if the examinee was female. CONCLUSIONS: These findings of examiner effects, even in standardized situations, may influence outcome even when students perform equally well. Examiners need to be made aware of these biases prior to examining.

Pruritus is associated with severely impaired quality of life in patients with primary sclerosing cholangitis.

OBJECTIVES: Quality of life, fundamental to the individual patient, has shown a lack of correlation with severity in research on several diseases. Thus, we aimed to identify factors associated with quality of life in patients with primary sclerosing cholangitis. METHODS: The Short Form Health Survey and the Patient Health Questionnaire were used to assess quality of life and depression. Complete data sets of 113 patients were analyzed for correlation with sex, age, presence of concomitant inflammatory bowel disease and dominant stenosis, frequency of pruritus, and Mayo Risk Score. RESULTS: Physical functioning decreased with age (P<0.001). Further, women experienced more prominent role limitations because of physical (P<0.03) and emotional (P<0.01) problems. Although patients' quality of life and depression scores were only slightly lower than normal, more frequent pruritus was associated with a considerable reduction in quality of life in terms of physical and social functioning, general and mental health, bodily pain, vitality, and roles (because of physical problems) (P<0.01). It did not differ significantly according to the Mayo Risk Score or the presence of dominant stenoses. Depression scores were only significantly affected in patients with more frequent pruritus. CONCLUSION: Pruritus severely affects quality of life in patients with primary sclerosing cholangitis and is associated with depression to varying extents, although the most commonly used parameters of disease severity do not correspond to quality of life in these patients. These findings need to be considered with respect to treatment outcomes and indications for liver transplantation.

Undergraduate curricula in palliative medicine: a systematic analysis based on the palliative education assessment tool.

BACKGROUND: By law in 2013, palliative medicine will be integrated into the undergraduate curriculum as part of a mandatory training program and examinations at German medical schools. For this reason a national curriculum in palliative medicine has to be developed. AIM: The aim of this study was to analyze international undergraduate curricula in palliative medicine, and thus support further curriculum development in Germany. DESIGN: Available international curricula were sought through general search engines (Google, Medline/Pubmed) in German and/or the English language. We used the palliative care education assessment tool (PEAT) for analysis of available curricula. The PEAT comprises 7 domains, and 83 objectives. RESULTS: We identified 17 international undergraduate curricula on palliative medicine. There was a wide variation in curricular design. Mapping the curricula, the results showed that five of the seven PEAT domains were represented in the curricula retrieved. Sixteen objectives were included in more than 75% and 46 objectives in up to 50% of the curricula, respectively. Eighteen objectives were included in less than 25% of the curricula. Three PEAT objectives were absent in all curricula examined. CONCLUSION: There is an overlap between objectives presented in the PEAT and in the curricula, suggesting that there are "core objectives" such as "respect for differing values," "bereavement process," and "use of opioids" which might be mandatory for undergraduate palliative medical education.

Does medical students' preference of test format (computer-based vs. paper-based) have an influence on performance?

BACKGROUND: Computer-based examinations (CBE) ensure higher efficiency with respect to producibility and assessment compared to paper-based examinations (PBE). However, students often have objections against CBE and are afraid of getting poorer results in a CBE.The aims of this study were (1) to assess the readiness and the objections of students to a CBE vs. PBE (2) to examine the acceptance and satisfaction with the CBE on a voluntary basis, and (3) to compare the results of the examinations, which were conducted in different formats. METHODS: Fifth year medical students were introduced to an examination-player and were free to choose their format for the test. The reason behind the choice of the format as well as the satisfaction with the choice was evaluated after the test with a questionnaire. Additionally, the expected and achieved examination results were measured. RESULTS: Out of 98 students, 36 voluntarily chose a CBE (37%), 62 students chose a PBE (63%). Both groups did not differ concerning sex, computer-experience, their achieved examination results of the test, and their satisfaction with the chosen format. Reasons for the students' objections against CBE include the possibility for outlines or written notices, a better overview, additional noise from the keyboard or missing habits normally present in a paper based exam. The students with the CBE tended to judge their examination to be more clear and understandable. Moreover, they saw their results to be independent of the format. CONCLUSIONS: Voluntary computer-based examinations lead to equal test scores compared to a paper-based format.

A stepwise psychotherapy intervention for reducing risk in coronary artery disease (SPIRR-CAD) - rationale and design of a multicenter, randomized trial in depressed patients with CAD.

OBJECTIVE: Depressive symptoms are highly relevant for the quality of life, health behavior, and prognosis in patients with coronary artery disease (CAD). However, previous psychotherapy trials in depressed CAD patients produced small to moderate effects on depression, and null effects on cardiac events. In this multicentre psychotherapy trial, symptoms of depression are treated together with the Type D pattern (negative affectivity and social inhibition) in a stepwise approach. METHODS: Men and women (N=569, age 18-75 years) with any manifestation of CAD and depression scores ≥ 8 on the Hospital Anxiety and Depression Scale (HADS), will be randomized (allocation ratio 1:1) into the intervention or control group. Patients with severe heart failure, acutely life-threatening conditions, chronic inflammatory disease, severe depressive episodes or other severe mental illness are excluded. Both groups receive usual medical care. Patients in the intervention group receive three initial sessions of supportive individual psychotherapy. After re-evaluation of depression (weeks 4-8), patients with persisting symptoms receive an additional 25 sessions of combined psychodynamic and cognitive-behavioral group therapy. The control group receives one psychosocial counseling session. Primary efficacy variable is the change of depressive symptoms (HADS) from baseline to 18 months. Secondary endpoints include cardiac events, remission of depressive disorder (SCID) and Type D pattern, health-related quality of life, cardiovascular risk profile, neuroendocrine and immunological activation, heart rate variability, and health care utilization, up to 24 months of follow-up (ISRCTN: 76240576; NCT00705965).

An interdisciplinary and interactive online tool to manage the continuous development of learning objectives in a curriculum.

BACKGROUND: The last decades have brought about an unprecedented proliferation of scientific knowledge necessitating a structuring and standardization of content for the training of novices and junior staff in all academic disciplines. In medicine, great effort has been expended by individual faculties to compile learning objectives, yet one disadvantage is common to almost all of these catalogues: their static structure limits search options and impedes an ongoing development. METHODS: The learning objectives of all individual disciplines of the Heidelberg Curriculum Medicinale (HeiCuMed) were merged and assigned to levels and attributes of competency. In order to achieve easy access and to offer optimal search options to students, teaching staff and curriculum coordinators, the generated Heidelberg Catalogue of Learning Objectives (HCLO) was established as an online portal. RESULTS: The easy to handle online interface of the learning objectives catalogue allows for an individualized search for items with an unlimited combination of text and/or attributes. Thus, students and teaching staff may use the tool as a discipline-based guide for learning and teaching as well as an outcome oriented tool defining the intended competence of a graduate. Curriculum designers can continuously update the catalogue to map the currently intended course contents, thus ensuring fast adaptation to changing needs and rendering a dynamic feature to the HCLO. CONCLUSIONS: All members of the academic community may benefit from the presented model. Students are offered the opportunity to prepare for upcoming courses and examinations and to monitor their progress of competencies over the entire curriculum. Teaching staff and curriculum designers are supported in developing intended learning spirals and aligning learning objectives, course content and examination modalities. In its immediacy the HCLO provides the base for an advanced and fast adaptation in curriculum design as opposed to the static catalogues of objectives collecting dust. With this tool we would like to contribute to ongoing activities of curriculum designers in creating well-engineered and efficient tools to manage learning objectives.

Effect of exercise and respiratory training on clinical progression and survival in patients with severe chronic pulmonary hypertension.

BACKGROUND: Even though specific agents for the treatment of patients with pulmonary hypertension (PH) are available, in PH patients, physical capacity and quality of life (QoL) are often restricted and survival is reduced. OBJECTIVES: This study prospectively investigated the long-term effects of respiratory and exercise training in patients with severe chronic PH regarding safety, time to clinical worsening and survival. METHODS: Fifty-eight consecutive patients with severe PH on stable disease-targeted medication received exercise and respiratory training in hospital for 3 weeks and continued at home. They were prospectively followed for 24 ± 12 months. Primary endpoints were time to clinical worsening and survival. Adverse events and changes in the 6-min walking test, QoL, WHO functional class and gas exchange were secondary endpoints and were evaluated at baseline and at weeks 3 and 15. RESULTS: All patients tolerated the exercise training well without severe adverse events. In week 15, 6-min walking test results were significantly improved compared to baseline (by 84 ± 49 m, p < 0.001), as well as QoL scores, WHO functional class (from 2.9 ± 0.5 to 2.6 ± 0.6, p < 0.01), peak oxygen consumption (from 12.5 ± 3.0 to 14.6 ± 3.9 ml/min/kg, p < 0.001), heart rate at rest (from 75 ± 12 to 61 ± 18 beats/min, p < 0.001) and maximal workload (from 65 ± 21 to 80 ± 25 W, p < 0.001). Survival at 1 and 2 years was 100 and 95%, respectively. Fifteen events occurred during the follow-up. CONCLUSION: This study indicates that exercise and respiratory training as add-on to medical treatment may improve exercise capacity and QoL, and that they have a good long-term safety in the described setting.

Peak oxygen uptake and left ventricular ejection fraction, but not depressive symptoms, are associated with cognitive impairment in patients with chronic heart failure.

BACKGROUND: The aim of the present study was to assess cognitive impairment in patients with chronic heart failure (CHF) and its associations with depressive symptoms and somatic indicators of illness severity, which is a matter of controversy. METHODS AND RESULTS: Fifty-five patients with CHF (mean age 55.3 ± 7.8 years; 80% male; New York Heart Association functional class I-III) underwent assessment with an expanded neuropsychological test battery (eg, memory, complex attention, mental flexibility, psychomotor speed) to evaluate objective and subjective cognitive impairment. Depressive symptoms were assessed using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (SCID) and a self-report inventory (Hospital Anxiety and Depression Scale [HADS]). A comprehensive clinical dataset, including left ventricular ejection fraction, peak oxygen uptake, and a 6-minute walk test, was obtained for all patients. Neuropsychological functioning revealed impairment in 56% of patients in at least one measure of our neuropsychological test battery. However, the Mini Mental State Examination (MMSE) could only detect cognitive impairment in 1.8% of all patients, 24% had HADS scores indicating depressive symptoms, and 11.1% met SCID criteria for a depressive disorder. No significant association was found between depressive symptoms and cognitive impairment. Left ventricular ejection fraction was related to subjective cognitive impairment, and peak oxygen uptake was related to objective cognitive impairment. CONCLUSION: Cognitive functioning was substantially reduced in patients with CHF and should therefore be diagnosed and treated in routine clinical practice. Caution is advised when the MMSE is used to identify cognitive impairment in patients with CHF.

Exercise and respiratory training improve exercise capacity and quality of life in patients with severe chronic pulmonary hypertension.

BACKGROUND: Pulmonary hypertension (PH) is associated with restricted physical capacity, limited quality of life, and a poor prognosis because of right heart failure. The present study is the first prospective randomized study to evaluate the effects of exercise and respiratory training in patients with severe symptomatic PH. METHODS AND RESULTS: Thirty patients with PH (21 women; mean age, 50+/-13 years; mean pulmonary artery pressure, 50+/-15 mm Hg; mean World Health Organization [WHO] class, 2.9+/-0.5; pulmonary arterial hypertension, n=23; chronic thromboembolic PH, n=7) on stable disease-targeted medication were randomly assigned to a control (n=15) and a primary training (n=15) group. Medication remained unchanged during the study period. Primary end points were the changes from baseline to week 15 in the distance walked in 6 minutes and in scores of the Short Form Health Survey quality-of-life questionnaire. Changes in WHO functional class, Borg scale, and parameters of echocardiography and gas exchange also were assessed. At week 15, patients in the primary and secondary training groups had an improved 6-minute walking distance; the mean difference between the control and the primary training group was 111 m (95% confidence interval, 65 to 139 m; P<0.001). Exercise training was well tolerated and improved scores of quality of life, WHO functional class, peak oxygen consumption, oxygen consumption at the anaerobic threshold, and achieved workload. Systolic pulmonary artery pressure values at rest did not change significantly after 15 weeks of exercise and respiratory training (from 61+/-18 to 54+/-18 mm Hg) within the training group. CONCLUSIONS: This study indicates that respiratory and physical training could be a promising adjunct to medical treatment in severe PH. The effects add to the beneficial results of modern medical treatment.
