Competence By Design: a transformational national model of time-variable competency-based postgraduate medical education.

Postgraduate medical education is an essential societal enterprise that prepares highly skilled physicians for the health workforce. In recent years, PGME systems have been criticized worldwide for problems with variable graduate abilities, concerns about patient safety, and issues with teaching and assessment methods. In response, competency based medical education approaches, with an emphasis on graduate outcomes, have been proposed as the direction for 21st century health profession education. However, there are few published models of large-scale implementation of these approaches. We describe the rationale and design for a national, time-variable competency-based multi-specialty system for postgraduate medical education called Competence by Design. Fourteen innovations were bundled to create this new system, using the Van Melle Core Components of competency based medical education as the basis for the transformation. The successful execution of this transformational training system shows competency based medical education can be implemented at scale. The lessons learned in the early implementation of Competence by Design can inform competency based medical education innovation efforts across professions worldwide.

Competence by Design: The Role of High-Stakes Examinations in a Competence Based Medical Education System.

Competency based medical education is developed utilizing a program of assessment that ideally supports learners to reflect on their knowledge and skills, allows them to exercise a growth mindset that prepares them for coaching and eventual lifelong learning, and can support important progression and certification decisions. Examinations can serve as an important anchor to that program of assessment, particularly when considering their strength as an independent, third-party assessment with evidence that they can predict future physician performance and patient outcomes. This paper describes the aims of the Royal College of Physicians and Surgeons of Canada's ("the Royal College") certification examinations, their future role, and how they relate to the Competence by Design model, particularly as the culture of workplace assessment and the evidence for validity evolves. For example, high-stakes examinations are stressful to candidates and focus learners on exam preparation rather than clinical learning opportunities, particularly when they should be developing greater autonomy. In response, the Royal College moved the written examination earlier in training and created an exam quality review, by a specialist uninvolved in development, to review the exam for clarity and relevance. While learners are likely to continue to focus on the examination as an important hurdle to overcome, they will be preparing earlier in training, allowing them the opportunity to be more present and refine their knowledge when discussing clinical cases with supervisors in the Transition to Practice phase. The quality review process better aligns the exam to clinical practice and can improve the educational impact of the examination preparation process.

Medications and dosages used in medical assistance in dying: a cross-sectional study.

BACKGROUND: There is little evidence describing the technical aspects of medical assistance in dying (MAiD) in Canada, such as medications, dosages and complications. Our objective was to describe clinical practice in providing MAiD in Ontario and Vancouver, Canada, and explore relations between medications used, time until death and complications. METHODS: We conducted a retrospective cohort study of a sample of adult (age ≥ 18 yr) patients who received MAiD in Ontario between 2016 and 2018, and patients who received MAiD in 1 of 3 Canadian academic hospitals (in Hamilton and Ottawa, Ontario, and Vancouver, British Colombia) between 2019 and 2020. We used de-identified data for 2016-2018 from the Office of the Chief Coroner for Ontario MAiD Database and chart review data for 2019-2020 from the 3 centres. We used multivariable parametric survival analysis to identify relations between medications, dosages and time from procedure start until death. RESULTS: The sample included 3557 patients (1786 men [50.2%] and 1770 women [49.8%] with a mean age of 74 [standard deviation 13] yr). The majority of patients (2519 [70.8%]) had a diagnosis of cancer. The medications most often used were propofol (3504 cases [98.5%]), midazolam (3251 [91.4%]) and rocuronium (3228 [90.8%]). The median time from the first injection until death was 9 (interquartile range 6) minutes. Standard-dose lidocaine (40-60 mg) and high-dose propofol (> 1000 mg) were associated with prolonged time until death (prolonged by a median of 1 min and 3 min, respectively). Complications occurred in 41 cases (1.2%), mostly related to venous access or need for administration of a second medication. INTERPRETATION: In a large sample of patients who died with medical assistance, certain medications were associated with small differences in time from injection to death, and complications were rare. More research is needed to identify the medication protocols that predict outcomes consistent with patient and family expectations for a medically assisted death.

Systematic review and narrative synthesis of competency-based medical education in anaesthesia.

BACKGROUND: Competency-based medical education (CBME) addresses the accountability of postgraduate training programmes to graduate specialists capable of independent practice. METHODS: We undertook a systematic review and narrative synthesis of the published CBME literature in anaesthesia training programmes to identify current practices and areas requiring further exploration. RESULTS: We grouped the 23 studies that met our inclusion criteria into the following categories: demonstrating outcomes of CBME, developing a consensus on an achievable CBME curriculum, CBME curriculum framework, design and implementation of workplace-based assessment (WBA) tools, trainee self-assessment, perceptions of trainees and supervisors on WBA tools, and technological solutions for assessment and feedback. Included studies reported variable success in reaching consensus in competency outcome frameworks for sequenced progression and limited research on approaches to curriculum delivery, whilst the majority of studies focused on workplace assessment. Studies supported the use of entrustment scales, where assessors make a judgement on the extent to which the trainee can manage a case independently. While evidence supported the reliability of WBA tools, and predicted the numbers needed for high-stakes decisions, areas of concern related to factors influencing the value WBA tools in promoting trainee learning, and variable perceptions of their value in making decisions on progression. CONCLUSIONS: Evidence on outcomes of CBME was limited to acquisition of specific competencies during training. The large number of unanswered questions and the dearth of studies across the core components of CBME suggest that we need a collaborative approach to create the evidence required to implement CBME wisely and cost effectively, to have positive impacts on patients, trainees, and healthcare systems.

Oral medical assistance in dying (MAiD): informing practice to enhance utilization in Canada.

The legislation Bill C-14 legalized medical assistance in dying (MAiD) in Canada. After thorough assessments of eligibility by two clinicians, Bill C-14 allows for both intravenous-assisted death by a clinician (euthanasia) and prescription of oral medication for self-administration (assisted suicide). Nevertheless, since inception in June 2016, intravenous euthanasia is the main form of delivery of assisted death in Canada. The reasons why oral MAiD is underutilized in Canada are multifactorial. Currently, there is no consensus on either the medications or the protocols for oral administration, nor a comprehensive understanding of the potential side effects and complications associated with different regimens. The quality of evidence for optimal MAiD medications is low, so any suggested recommendations can only be informed by the global but generally anecdotal experience. The challenges for implementing oral MAiD in Canada include a need to enhance clinician comfort in prescribing oral medications as an alternative to intravenous administration. The goals for ideal oral MAiD medications are 100% effectiveness and minimal side effects, while ensuring that the needed dose is both palatable and deliverable in a tolerable oral volume. The Netherlands has the most experience worldwide and barbiturates have emerged as the most common, efficacious, and tolerable agents by patients. Based on this global experience and the over-arching goals for oral MAiD, we recommend the use of a secobarbital suspension combined with antiemetic prophylaxis.

Impact of visualization on simulation training for vascular anastomosis.

OBJECTIVE: There is mounting evidence supporting the benefit of surgical simulation on the learning of skills independently and in a patient-safe environment. The objective of this study was to examine the effect of visualization of surgical steps via instructional media on performance of an end-to-side microvascular anastomosis. METHODS: Thirty-two first- and second-year surgical trainees from the University of Ottawa received an expert-guided, didactic lecture on vascular anastomosis and performed an end-to-side anastomosis on a procedural model to assess baseline skills. Assessments were performed by 2 blinded, expert observers using validated measurements of skill. Subjects were then proctored to perform anastomoses using the model. Subjects were then randomized to watch an instructional video on performance of vascular anastomosis using visualization as the education strategy. One week later, subjects were again assessed for technical skill on the model. The primary outcome was the score achieved on the Objective Structured Assessment of Technical Skill (OSATS) scale. Secondary outcomes included an anastomosis-specific End-Product Rating Score and time to completion. RESULTS: Compared with residents who received expert-guided simulator training alone, those who used the supplementary multimedia scored significantly greater on OSATS (17.4 ± 2.9 vs 14.2 ± 3.2, P = .0013) and on End-Product Rating Score (11.24 ± 3.0 vs 7.4 ± 4.1, P = .011). However, performance time did not differ between groups (15.7 vs 14.3 minutes, P = .79). CONCLUSIONS: Residents with supplemental instructional media performed an end-to-side anastomosis more proficiently as assessed by OSATS and with a greater quality end-product. This suggests that both didactic simulation training as well as use of visualization multimedia improves learning and performance of vascular anastomosis and should be incorporated into surgical curricula.

Acquiring and maintaining point-of-care ultrasound (POCUS) competence for anesthesiologists.

PURPOSE: Point-of-care ultrasound (POCUS) involves the bedside use of ultrasound to answer specific diagnostic questions and to assess real-time physiologic responses to treatment. Although POCUS has become a well-established resource for emergency and critical care physicians, anesthesiologists are still working to obtain POCUS skills and to incorporate them into routine practice. This review defines the benefits of POCUS to anesthesia practice, identifies challenges to establishing POCUS in routine anesthesia care, and offers solutions to help guide its incorporation going forward. PRINCIPAL FINDINGS: Benefits to POCUS include improving the sensitivity and specificity of the physical examination and helping to guide patient treatment. The challenges to establishing POCUS as a standard in anesthesia practice include developing and maintaining competence. There is a need to develop standards of practice and a common language between specialties to facilitate training and create guidelines regarding patient management. CONCLUSIONS: Presently, our specialty requires consensus by expert stakeholders to address issues of competence, certification, development of standards and terminology, and the management of unexpected diagnoses. To promote POCUS competency in our discipline, we support its incorporation into anesthesiology curricula and training programs and the continuing professional development of POCUS-related activities at a national level.

Interactive Online Learning for Attending Physicians in Ultrasound-guided Central Venous Catheter Insertion.

Evidence has demonstrated that the use of dynamic ultrasound guidance (USG) for central venous catheter (CVC) significantly decreases attempts, failures, and complication rates. Despite national organizations recommending the use of USG and its increasing availability, USG is used inconsistently and non-uniformly. We sought to determine if an online training module for CVC insertion with ultrasound guidance will improve acquisition and long-term retention of knowledge and skills for attending physicians. Participants were tested for declarative knowledge and skills on a simulator (pre-test) for ultrasound-guided CVC insertion at baseline. They then completed an online learning module followed by an immediate post-test and a six-month retention test. There were 16 attending physicians who participated in the study. The CVC training module increased declarative knowledge acquisition and retention. No significant difference in simulated CVC performance was found over the three time points.

Metronidazole and Norfloxacin induced Generalized Fixed Drug Eruptions in an adult male patient - A Case Report.

INTRODUCTION: Fluoroquinolones are most widely used for empirical treatment of gastrointestinal disease due to emergence of drug resistant strains to other antimicrobials. They are also indulged in cutaneous adverse drug reactions with varying form of severity. CASE PRESENTATION: A 43 year old male patient developed fixed drug eruptions after administration of tablet norfloxacin and metronidazole for treatment of colicky abdominal pain with diarrhoea. Erythematous rashes involved whole body including buccal mucosa. Causative drugs were stopped and patient was managed by local as well as systemic therapy and was recovered after 20 days. CONCLUSION: Awareness among healthcare professionals regarding FDEs and its management is essential to prevent mortality and morbidity and counsel patient regarding future use of drugs causing reactions with physician's advice.

Hospitalizations due to preventable adverse reactions-a systematic review.

PURPOSE: The study aimed to measure the percentage of preventable adverse drug reactions that lead to the hospitalization (PADRAd) and to explore the heterogeneity in its estimation through subgroup analysis of study characteristics. METHODS: Two investigators independently searched in electronic databases and related bibliography for prospective studies involving PADRAd. We excluded studies investigating medication errors and spontaneous and retrospective reporting. The primary outcome was PADRAd percentage. To explore the heterogeneity, we performed subgroup analysis based on study region, wards, age groups, adverse drug reaction (ADR) definitions, preventability assessment, ADR identification methods, study duration and sample size. We explored fatal PADRAd and causative drugs as a secondary outcome. We used the generic inverse variance method with random effect model to compute meta-analytic summary. RESULTS: Of the 68 full-text articles assessed, we included 22 studies. The mean PADRAd percentage was 45.11 % (95 % CI = 33.06-57.15; I 2 = 99 %). Studies including elderly (63.31 %) and all age groups (49.03 %) showed higher percentages than paediatric population (16.40 %). Studies examining all hospital populations showed higher percentages than specific wards. We observed high percentages in studies using Edwards and Aronson as an ADR definition and Hallas et al. as a preventability assessment tool. After age group adjustment, ADR detection methods did not show significant difference. The fatal PADRAd percentage was 1.58 % (95 % CI = -0.60 to 3.76; I 2 = 47 %). Paediatric and elderly studies showed a different causative drug pattern. CONCLUSION: Variation in PADRAd across the studies can be explained by difference in study populations and data collection methods. Extrapolation of preventable reactions should be carried out considering all these factors with caution.

EVALUATION OF ANTICOAGULANT EFFECT OF SULFATED POLYSACCHARIDE (SPS) FROM CODIUM DWARKENSE BORGESEN IN κ-CARRAGEENAN INDUCED HYPERCOAGULABLE STATE IN WISTAR ALBINO RATS.

Our aim of the present study was to evaluate the anticoagulant effect of sulfated polysaccharides (SPS) from Codium dwarkense Bergesen in ic-carrageenan induced hypercoagulable state in Wistar albino rats. 48 Wistar albino rats of either sex were randomly divided into 6 groups - disease control, active control, treatment lowmand high dose and preventive low and high dose. K-Carrageenan (3 mg/kg) single dose intravenously was given in rat tail vein at pre-decided time to produce hypercoagulable state. Baseline, 24, 48 and 72 hours duration blood samples were collected for PT, INR, aPTT, platelet count and fibrinogen level, FDP and D-Dimer measurements. At the end of experiment, animals were sacrificed for histopathology analysis of lung, liver and mesentery. Sulfated polysaccharide (SPS) significantly restored altered coagulation parameters (PT, INR, aPTI, platelet count and fibrinogen level) without affecting fibrinolytic parameters (FDP and D-Dimer). Administration of SPS both as a treatment and preventive therapy reduced the number of microthrombi along with less structural damage in histopathology of lung, liver and mesentery. Heparin served as active control and its administration significantly prolonged aPT' and restored PT. This study shows, anticoagulant activity of SPS extracted from Codium dwarkense Bergesen in Wistar albino rats.

Triamcinolone Acetonide and Bevacizumab Induced Raised Intraocular Pressure in An Elderly Male Diabetic Patient - A Case Report.

Intravitreal triamcinolone and bevacizumab are emerging treatment modalities for the patients of macular oedema; however, they are known to raise intraocular pressure. A 61 year old diabetic male patient developed glaucoma after administration of triamcinolone acetonide and bevacizumab intravitreally for treatment of macular oedema. His intraocular pressure was raised up to about 42 mm Hg. Such high and sustained rise in intraocular pressure may lead to vision loss by damaging the optic nerve. The patient was managed by local as well as systematic therapy and was recovered after 1 month from the occurrence of an event. Intraocular pressure should be monitored in patients receiving intravitreal triamcinolone and bevacizumab. Risk benefit analysis must be done before using IVTA and IVB in patients with diabetic macular oedema.

Program director and resident perspectives of a competency-based medical education anesthesia residency program in Canada: a needs assessment.

PURPOSE: In July 2015, the University of Ottawa introduced a competency-based medical education (CBME) postgraduate program for anesthesia. Prior to program implementation, this study aimed to identify Canadian anesthesiology program directors perceptions of CBME and residents' opinion on how the program should be designed and perceived consequences of CBME. METHODS: This two-phase, qualitative study included semi-structured interviews with Canadian anesthesia program directors (Phase I) and a focus group interview with residents enrolled in the University of Ottawa time-based anesthesia program (Phase II). Both phases sought to gauge participant's perceptions of CBME. Interviews were recorded, transcribed verbatim and thematically analyzed. RESULTS: Data was combined to protect anonymity of the six participants (three program directors and three residents). Participants spoke about the perceived advantages of CBME, the need to establish definitions, and challenges to a CBME program highlighting logistical factors, implications for trainees and the role assessment plays in CBME. CONCLUSION: These findings will inform CBME implementation strategies in anesthesia programs across the country, and may assist other residency programs in the design of their programs. Furthermore, our findings may help identify potential challenges and issues that other postgraduate specialties may face as they transition to a CBME model.

Effectiveness and tolerability of short course co-trimoxazole, norfloxacin and levofloxacin in bacteriological cure of uncomplicated urinary tract infection in outpatient setting. An open label, parallel group, randomized controlled trial.

To compare the bacteriological cure rate of short-course (3-day) treatment of uncomplicated urinary tract infection (UTI) using co-trimoxazole, norfloxacin and levofloxacin, patients with uncomplicated UTI were randomized to receive either co-trimoxazole (960 mg) twice a day or norfloxacin (400 mg) twice a day or levofloxacin (250 mg) once a day for three days. Urine culture was done at the end of treatment and evaluated for bacteriological cure rate in each group. Among a total of 175 patients, Escherichia coli (74.29%) was the most common organism isolated followed by Klebsiella (11.43%), Streptococcus (6.29%), Staphylococcus saphrophyticus (5.14%), and Pseudomonas (2.86%). At the end of three days' treatment, bacteriological cure rates were 86.2%, 87.7% and 83.3% for co-trimoxazole, norfloxacin and levofloxacin, respectively (p>0.05). Therefore short-course treatment with co-trimoxazole 960 mg twice a day, norfloxacin 400 mg twice a day and levofloxacin 250 mg once a day are almost equally effective for treatment of uncomplicated UTI.
