Examining the educational impact of the mini-CEX: a randomised controlled study.

BACKGROUND: The purpose of this study is to evaluate the mini-Clinical Evaluation Exercise (mini-CEX) as a formative assessment tool among undergraduate medical students, in terms of student perceptions, effects on direct observation and feedback, and educational impact. METHODS: Cluster randomised study of 38 fifth-year medical students during a 16-week clinical placement. Hospitals were randomised to provide a minimum of 8 mini-CEXs per student (intervention arm) or continue with ad-hoc feedback (control arm). After finishing their clinical placement, students completed an Objective Structured Clinical Examination (OSCE), a written test and a survey. RESULTS: All participants in the intervention group completed the pre-planned number of assessments, and 60% found them to be useful during their clinical placement. Overall, there were no statistically significant differences between groups in reported quantity or quality of direct observation and feedback. Observed mean scores were marginally higher on the OSCE and written test in the intervention group, but not statistically significant. CONCLUSIONS: There is considerable potential in assessing medical students during clinical placements and routine practice, but the educational impact of formative assessments remains mostly unknown. This study contributes with a robust study design, and may serve as a basis for future research.

Continuous interprofessional coordination in perioperative work: an exploratory study.

Coordination of perioperative work is challenging. Advancements in diagnostic and therapeutic possibilities have not been followed by similar advancements in the ability to coordinate care. In this paper, we report on a study that explored the nature of continuous coordination as practiced by perioperative staff in order to coordinate their own activities with respect to those of their colleagues. We conducted in-depth interviews (n = 14), and combined observations and focused interviews (n = 31) with perioperative staff (physicians, nurses, technicians, and cleaners) at a major university hospital in Norway. Data were analysed qualitatively with systematic text condensation. The results indicated that a surgical schedule was important for informing staff members about the cases and tasks they had been assigned. Staff also depended on ad hoc, explicit communication to ensure timeliness of particular perioperative activities. This, however, left little room for adjustments of other activities. Hence, to be able to proactively coordinate their own work some staff tried to predict future perioperative activities by observing the workplace, monitoring the surgical scheduling software for changes, and sharing their colleagues' progress updates and predictions. These findings could be important for those developing support for perioperative coordination.

Designing privacy-friendly digital whiteboards for mediation of clinical progress.

BACKGROUND: In hospitals, digital versions of dry-erase whiteboards are increasingly becoming more common. One of the purposes with such whiteboards is to support coordination of care by augmenting visibility and availability of clinical information. However, clinical information usually concerns patients and is regarded as sensitive personal health information, meaning that it should be access controlled. The purpose of this study is to explore how digital whiteboards can be designed for supporting coordination of care, by providing clinicians with useful information in a usable way, and at the same time protect patient privacy. METHODS: A demo application was designed, demonstrated and evaluated iteratively. In total, 15 professional ward nurses role-played a scenario in which the application played a central part. Afterwards, the participants were interviewed. All interviews were recorded, transcribed verbatim, and analysed qualitatively. RESULTS: The participants valued having updated clinical information presented on a digital whiteboard, even if the information was de-identified and abstracted. According to the participants, such information could possibly improve inter-departmental communication, reduce the number of electronic health record-logins, and make nurses more rapidly aware of new information. The participants expected that they would be able to re-identify much of the de-identified information in real situations based on their insight into their patients' recent and expected care activities. Moreover, they also valued being able to easily access more detailed information and verify patient identities. While abstraction and de-identification was regarded to sufficiently protect the patients' privacy, the nurses also pointed out the importance of having control over what can be seen by other patients and passers-by if detailed medical information was accessed on a digital whiteboard. CONCLUSIONS: Presenting updated information from patient care activities on a digital whiteboard in a de-identified and abstracted format may support coordination of care at a hospital ward without compromising patient privacy.

Avoidable emergency admissions?

BACKGROUND: Use of specialist healthcare services is increasing. AIM: To evaluate whether alternative healthcare services could reduce the need for admissions to specialist care hospitals. DESIGN: Prospective observational study of emergency referrals for admission to specialist care. SETTING: A single out-of-hours primary care centre (OPCC) in Norway. METHOD: Out-of-hours physicians registered their referrals for hospital admission and stated whether the admission could have been avoided given the availability of six other healthcare services. RESULTS: Of 1083 registered encounters at the OPCC, 152 (14%) were referred for specialist care hospital admission. According to the referring physician, 32 (21%) of these referrals could have been avoided. The most eligible alternatives to such referrals were next-day appointments at a specialist outpatient clinic (11 of 32 referrals), or admission to a community hospital (21 of 32 referrals), or a nursing home (nine of 32 referrals). Respiratory (eight of 32 referrals) and gastrointestinal problems (12 of 32 referrals) were the most common among avoidable admissions. CONCLUSIONS: The use of specialist care hospital admission can be reduced if appropriate alternatives are available.

Information and communication needs of healthcare workers in the perioperative domain.

Perioperative work requires the collaborative efforts of a multitude of actors. Coordinating such collaboration is challenging, and coordination breakdowns may be very expensive and jeopardize patient safety. We studied the needs for status information and projection of future status and events for key actors in the perioperative environment. We found that information and projection needs differed significantly between actors. While just-in-time notifications sufficed for some, others were dependent on projections to provide high quality and efficient care. Finally, information on current status and support in projecting the future unfolding of events could improve actors situated coordination capabilities.

Disease-associated reference intervals for twenty laboratory tests in patients with rheumatoid arthritis, Crohn's disease or ulcerative colitis.

BACKGROUND: Population based reference intervals are fundamental for interpreting results for quantitative laboratory tests. In patients with a specific chronic disorder, however, results of various tests may regularly be different than in healthy individuals. Health-associated reference intervals may therefore have limited value in such patients. Instead, disease-associated reference intervals may be useful, as they describe the results distribution in populations resembling the specific patients. Few disease-associated reference intervals are available in the literature. The aim of this study was to estimate reference intervals for common laboratory tests for patient populations with rheumatoid arthritis, Crohn's disease or ulcerative colitis without significant comorbidity, using a novel algorithm. MATERIAL AND METHODS: Laboratory test results and hospital discharge diagnoses were collected for relevant patients. An algorithm was developed to identify discharge diagnoses significantly associated with high or low results for specific tests. After excluding patients with such diagnoses, reference intervals were estimated, representing results distributions in patients with each of the specific chronic disorders, but without significant comorbidity. RESULTS: Disease-associated reference intervals were estimated for 20 common laboratory tests. Most of the estimated reference limits were significantly different from corresponding health-associated reference limits. Thirty percent of the estimated reference intervals were different from estimates based on crude patient populations, indicating that the algorithm applied managed to exclude patients with relevant comorbidity. CONCLUSION: Disease-associated reference intervals could be estimated for a number of tests in patients with rheumatoid arthritis, ulcerative colitis or Crohn's disease using a highly automated algorithm based on routinely recorded patient data.

Has "The Ceiling" Rendered the Readiness for Interprofessional Learning Scale (RIPLS) Outdated?

PURPOSE: The present study aimed to investigate the preliminary effects of collaborative learning and simulation on readiness to engage in and attitudes toward future interprofessional learning activities. We translated into Norwegian and validated the original Readiness for Interprofessional Learning Scale (RIPLS) (part 1) to measure the efficacy and feasibility of a structured collaborative learning activity (part 2). MATERIALS AND METHODS: Undergraduate social and health care professional students from five Norwegian universities (n = 307) participated in the validation stage of this study (part 1). A Norwegian version of the RIPLS was developed using forward and backward translation. An expert panel discussed discrepancies between the translations and professional concepts. We planned to conduct a principal component analysis to evaluate the structure, reliability, and internal consistency of the Norwegian version of the RIPLS, after investigating the skewness, kurtosis, and range of items included. One hundred fifty students participated in collaborative learning activities; 72 (48%) of these individuals answered the translated RIPLS questionnaire. RESULTS: We found a substantial ceiling effect in the majority of items in the RIPLS, making it difficult to use the instrument as a measure of change. We evaluated the efficacy and feasibility of the collaborative activities based on the changes in the single items that had sufficient univariate normality and ultimately confirmed positive changes in two of these items. CONCLUSION: Norwegian students appear ready for interprofessional learning; however, due to significant ceiling effects, the majority of items in the RIPLS no longer seem suitable for measuring and evaluating the effects of interprofessional learning (part 1). Single-item analysis revealed a potential effect of collaborative learning (part 2). A new questionnaire is needed where readiness is instead understood as self-efficacy in areas such as role awareness and interprofessional communication. Researchers should be aware that even previously validated questionnaires may lose their applicability over time and require revision. Demands for interprofessional learning and practice are continuously evolving, and evaluation methods should be adjusted accordingly.

Express Team-Based Learning (eTBL): A Time-Efficient TBL Approach in Neuroradiology.

RATIONALE AND OBJECTIVES: Team-based learning (TBL) is a student-centred, teacher-directed instructional method that promotes active learning. The application phase of TBL stimulates group discussion and critical thinking, which could be useful for learning radiology. We designed and evaluated two modified TBL-sessions on computed tomography and magnetic resonance imaging diagnostics in neuroradiology. Our aim was to examine what effects engaging students in in-class team application tasks had on student learning. MATERIALS AND METHODS: A cross-over study was conducted, including 105 third-year medical students using two modified TBL sessions as the active learning intervention compared with two traditional lectures as a control. Student learning was assessed by results on the neuroradiology part of the end-of-year written examination. Student engagement and perceptions were assessed using the Student Self-Report of Engagement Measure and an additional four Likert-type items. RESULTS: There were no statistically significant differences in student scores on the examination. Students reported high levels of engagement, and reported being more satisfied overall with the TBL sessions than traditional lectures. Students rated the TBL sessions higher than lectures on ability to make difficult material comprehensible, ability to engage students and to give them feedback. CONCLUSION: The modified TBL sessions halved in-class teaching time and by omitting the readiness assurance tests, there was more in-class time to focus on problem-solving of real clinical cases. Moreover, shorter sessions may ease implementation of TBL in the curriculum and allow for more frequent sessions. Students were more satisfied with eTBL than lectures, and reported high levels of engagement.

How Do Experienced Physicians Access and Evaluate Laboratory Test Results for the Chronic Patient? A Qualitative Analysis.

BACKGROUND: Electronic health records may present laboratory test results in a variety of ways. Little is known about how the usefulness of different visualizations of laboratory test results is influenced by the complex and varied process of clinical decision making. OBJECTIVE: The purpose of this study was to investigate how clinicians access and utilize laboratory test results when caring for patients with chronic illness. METHODS: We interviewed 10 attending physicians about how they access and assess laboratory tests when following up patients with chronic illness. The interviews were audio-recorded, transcribed verbatim, and analyzed qualitatively. RESULTS: Informants preferred different visualizations of laboratory test results, depending on what aspects of the data they were interested in. As chronic patients may have laboratory test results that are permanently outside standardized reference ranges, informants would often look for significant change, rather than exact values. What constituted significant change depended on contextual information (e.g., the results of other investigations, intercurrent diseases, and medical interventions) spread across multiple locations in the electronic health record. For chronic patients, the temporal relations between data could often be of special interest. Informants struggled with finding and synthesizing fragmented information into meaningful overviews. CONCLUSION: The presentation of laboratory test results should account for the large variety of associated contextual information needed for clinical comprehension. Future research is needed to improve the integration of the different parts of the electronic health record.

[Biopsies of the endoscopically normal colon]. / Biopsi ved normal koloskopi.

BACKGROUND: The importance of biopsies of the endoscopically normal colonic mucosa is controversial. MATERIAL AND METHODS: All patients who underwent total colonoscopy at St. Olav"s Hospital in 2004 were considered for inclusion if their colonoscopy was normal. Patients who were already enrolled in follow-up protocols were excluded. Biopsy practice and histological findings were recorded. RESULTS: Biopsies were taken in 266 of 738 normal colonoscopies (36%) The number of biopsies per colonoscopy varied from 1 to 16 (median 6). Biopsies from 8 of the 266 patients (3.0%) showed histological abnormalities of certain clinical significance. Seven of the 8 patients were investigated because of diarrhoea. In addition, histological abnormalities of limited clinical significance were found in biopsies from 13 of the patients (4.9%). INTERPRETATION: Use of biopsy in the endoscopically normal colon varied considerably. Taking biopsies in patients without diarrhoea was of minor clinical importance. Guidelines for taking biopsies of the endoscopically normal colon are desirable.

Presentation of clinical laboratory results: an experimental comparison of four visualization techniques.

OBJECTIVE: To evaluate how clinical chemistry test results were assessed by volunteers when presented with four different visualization techniques. MATERIALS AND METHODS: A total of 20 medical students reviewed quantitative test results from 4 patients using 4 different visualization techniques in a balanced, crossover experiment. The laboratory data represented relevant patient categories, including simple, emergency, chronic and complex patients. Participants answered questions about trend, overall levels and covariation of test results. Answers and assessment times were recorded and participants were interviewed on their preference of visualization technique. RESULTS: Assessment of results and the time used varied between visualization techniques. With sparklines and relative multigraphs participants made faster assessments. With relative multigraphs participants identified more covarying test results. With absolute multigraphs participants found more trends. With sparklines participants more often assessed laboratory results to be within reference ranges. Different visualization techniques were preferred for the four different patient categories. No participant preferred absolute multigraphs for any patient. DISCUSSION: Assessments of clinical chemistry test results were influenced by how they were presented. Importantly though, this association depended on the complexity of the result sets, and none of the visualization techniques appeared to be ideal in all settings. CONCLUSIONS: Sparklines and relative multigraphs seem to be favorable techniques for presenting complex long-term clinical chemistry test results, while tables seem to suffice for simpler result sets.

What is optimal timing for trauma team alerts? A retrospective observational study of alert timing effects on the initial management of trauma patients.

BACKGROUND: Trauma teams improve the initial management of trauma patients. Optimal timing of trauma alerts could improve team preparedness and performance while also limiting adverse ripple effects throughout the hospital. The purpose of this study was to evaluate how timing of trauma team activation and notification affects initial in-hospital management of trauma patients. METHODS: Data from a single hospital trauma care quality registry were matched with data from a trauma team alert log. The time from patient arrival to chest X-ray, and the emergency department length of stay were compared with the timing of trauma team activations and whether or not trauma team members received a preactivation notification. RESULTS: In 2009, the trauma team was activated 352 times; 269 times met the inclusion criteria. There were statistically significant differences in time to chest X-ray for differently timed trauma team activations (P = 0.003). Median time to chest X-ray for teams activated 15-20 minutes prearrival was 5 minutes, and 8 minutes for teams activated <5 minutes before patient arrival. Timing had no effect on length of stay in the emergency department (P = 0.694). We found no effect of preactivation notification on time to chest X-ray (P = 0.474) or length of stay (P = 0.684). CONCLUSION: Proactive trauma team activation improved the initial management of trauma patients. Trauma teams should be activated prior to patient arrival.
