Should Objective Structured Clinical Examinations Assist the Clinical Competency Committee in Assigning Anesthesiology Milestones Competency?

BACKGROUND: With the integration of Objective Structured Clinical Examinations into the Anesthesiology primary board certification process, residency programs may choose to implement Objective Structured Clinical Examinations for resident skill assessment. The aim of this study was to evaluate Objective Structured Clinical Examination-based milestone assessment and compare with Clinical Competency Committee milestone assessment that is based purely on clinical evaluations. METHODS: An annual Objective Structured Clinical Examination event was used to obtain milestone assessment of clinical anesthesia year 0-clinical anesthesia year 3 residents for selected milestones in patient care, professionalism, and interpersonal/communication skills. The Objective Structured Clinical Examination scenarios were different for each training level. The Clinical Competency Committee evaluated each resident semiannually based on clinical evaluations of resident performance. The Clinical Competency Committee milestone assessments from 2014 to 2016 that were recorded closest to the Objective Structured Clinical Examination event (±3 months) were compared to the Objective Structured Clinical Examination milestone assessments. A total of 35 residents were included in this analysis in 3 different training cohorts: A (graduates 2016, n = 12); B (graduates 2017, n = 10); and C (graduates 2018, n = 13). All residents participated in Objective Structured Clinical Examinations because their clinical anesthesia year 0 year and Clinical Competency Committee milestone data had been reported since December 2014. RESULTS: Both assessment techniques indicated a competency growth proportional to the length in training. Despite limited cumulative statistics in this study, average trends in the Objective Structured Clinical Examination-Clinical Competency Committee relationship indicated: (1) a good proportionality in reflecting competency growth; (2) a grade enhancement associated with Clinical Competency Committee assessment, dominated by evaluations of junior residents (clinical anesthesia year 0-clinical anesthesia year 1); and (3) an expectation bias in Clinical Competency Committee assessment, dominated by evaluation of senior residents (clinical anesthesia year 2-clinical anesthesia year 3). CONCLUSIONS: Our analysis confirms the compatibility of the 2 evaluation methods in reflecting longitudinal growth. The deviation of Objective Structured Clinical Examination assessments versus Clinical Competency Committee assessments suggests that Objective Structured Clinical Examinations may be providing additional or different information on resident performance. Educators might consider using both assessment methods to provide the most reliable and valid competency assessments during residency.

Calcinosis Universalis: Cause for a Hard Airway.

Calcinosis universalis is a rare subtype of connective tissue diseases known as calcinosis cutis. The disease is described as diffuse calcium salt deposits in subcutaneous, fibrous muscle structures, and tendons. Calcinosis cutis typically occurs secondary to a tissue damaging disease such as dermatomyositis, systemic lupus erythematosus, and Sjogren syndrome, presenting before age 20 and predominantly affecting women. Calcinosis universalis presents challenges for anesthesia providers as joint calcification can make positioning difficult, vascular access becomes increasingly difficult over time as iatrogenic calcifications limit access sites, and pharyngeal and epiglottic structures can be involved leading to obstruction of the airway. However, anesthesia management of these patients has rarely been reported in the literature. We present a patient with calcinosis universalis with reported difficult airway who was scheduled for endoscopic ultrasound guided biopsy necessitating general anesthesia.

Efficacy and Use of Cloth Masks: A Scoping Review.

During the coronavirus disease 2019 (COVID-19) pandemic, there has been a global shortage of personal protective equipment (PPE). In this setting, cloth masks may play an important role in limiting disease transmission; however, current literature on the use of cloth masks remains inconclusive. This review aims to integrate current studies and guidelines to determine the efficacy and use of cloth masks in healthcare settings and/or the community. Evidence-based suggestions on the most effective use of cloth masks during a pandemic are presented. Embase, MEDLINE, and Google Scholar were searched on March 31, 2020, and updated on April 6, 2020. Studies reporting on the efficacy, usability, and accessibility of cloth masks were included. Additionally, a search of guidelines and recommendations on cloth mask usage was conducted through published material by international and national public health agencies. Nine articles were included in this review after full-text screening. The clinical efficacy of a face mask is determined by the filtration efficacy of the material, fit of the mask, and compliance to wearing the mask. Household fabrics such as cotton T-shirts and towels have some filtration efficacy and therefore potential for droplet retention and protection against virus-containing particles. However, the percentage of penetration in cloth masks is higher than surgical masks or N95 respirators. Cloth masks have limited inward protection in healthcare settings where viral exposure is high but may be beneficial for outward protection in low-risk settings and use by the general public where no other alternatives to medical masks are available.

Large-Scale Counting and Localization of Pineapple Inflorescence Through Deep Density-Estimation.

Natural flowering affects fruit development and quality, and impacts the harvest of specialty plants like pineapple. Pineapple growers use chemicals to induce flowering so that most plants within a field produce fruit of high quality that is ready to harvest at the same time. Since pineapple is hand-harvested, the ability to harvest all of the fruit of a field in a single pass is critical to reduce field losses, costs, and waste, and to maximize efficiency. Traditionally, due to high planting densities, pineapple growers have been limited to gathering crop intelligence through manual inspection around the edges of the field, giving them only a limited view of their crop's status. Through the advances in remote sensing and computer vision, we can enable the regular inspection of the field and automated inflorescence counting enabling growers to optimize their management practices. Our work uses a deep learning-based density estimation approach to count the number of flowering pineapple plants in a field with a test MAE of 11.5 and MAPD of 6.37%. Notably, the computational complexity of this method does not depend on the number of plants present and therefore efficiently scale to easily detect over a 1.6 million flowering plants in a field. We further embed this approach in an active learning framework for continual learning and model improvement.

Multidisciplinary treatment of diabetic foot ulcers in Canadian Aboriginal and non-Aboriginal people.

BACKGROUND: Diabetic foot ulcers are a major cause of morbidity and mortality. This study evaluated the clinical outcomes in Canadian non-Aboriginal and Aboriginal diabetic patients with foot ulcers managed at a multidisciplinary, tertiary care diabetic foot clinic. METHODS: A retrospective review of medical records was done for 325 patients receiving care during a 2-year period. All patients were followed at least 1 year after the initial visit. RESULTS: There were 224 (69%) non-Aboriginal and 101 (31%) Aboriginal patients with 697 foot ulcers. At the initial office visit, 204 (63%) patients had lesions in Wagner grades 2-4. At the most recent evaluation (average, 79+/-73 weeks after initial clinic visit), 190 (58%) patients were rated as having a good outcome (either healed or healing), but a poor outcome (static, progression, amputation, or death) was noted in 135 (42%) patients. At the most recent evaluation, the majority of the 697 ulcers that were noted at the initial or subsequent clinic visits were healed. Aboriginal patients had a shorter average time from initial clinic visit to major lower extremity amputation (Aboriginal, 50+/-64 weeks; non-Aboriginal, 62+/-56 weeks; P<0.01). Residence in a rural or reserve community also correlated with shorter average time from initial clinic visit to major lower extremity amputation (rural or reserve, 45+/-56 weeks; urban, 66+/-61 weeks; P<0.002). When controlled for non-urban residence, Aboriginal ethnicity was not associated with poorer clinical outcome. Earlier major lower extremity amputation was significantly associated with non-urban residence, Aboriginal ethnicity, and arterial insufficiency. Poor clinical outcome was significantly associated with being referred with a lesion present, age greater than 60 years, prior lower extremity amputation or revascularization, arterial insufficiency, more than one lesion on initial presentation, longer duration of type 2 diabetes, and a higher initial Wagner grade for the most advanced lesion. CONCLUSIONS: A multidisciplinary diabetic foot clinic may be successful in treating diabetic foot ulcers in Aboriginal and non-Aboriginal people. However, the frequency of poor outcome is high, consistent with the high prevalence of associated significant risk factors in this population.

Oral antimicrobial therapy for diabetic foot osteomyelitis.

BACKGROUND: Osteomyelitis in the foot of a diabetic individual is a common complication of peripheral neuropathy, peripheral vascular disease, and infection. Operative facilities and home intravenous antibiotic therapy programs may not be available in remote or rural communities. Limited data are available regarding the treatment results of oral antimicrobial therapy, with or without limited office debridement for diabetic foot osteomyelitis. METHODS: This retrospective medical record review of 325 consecutive diabetic patients who were evaluated at a multidisciplinary foot clinic identified 94 (29%) patients with 117 episodes of osteomyelitis. The most common group of organisms isolated were aerobic gram-positive cocci, and the single most frequent organism was Staphylococcus aureus. A mean of 1.6 +/- 0.8 (range 1 to 4) pathogens were recovered per episode of osteomyelitis. Therapy was guided by culture results. There were 93 episodes of osteomyelitis (79 patients) that were treated with a mean of 3 +/- 1 oral antimicrobial agents (with or without an initial short course of intravenous antimicrobial agents) and had adequate followup to evaluate outcome of treatment; office treatment included bone debridement in 26 (28%) and toe amputation in nine (10%) of the 93 episodes (79 patients). RESULTS: Of the 93 episodes treated with oral antimicrobial agents (with or without an initial short course of intravenous antimicrobial agents), 75 (80.5%) episodes were put into remission. Mean duration of oral antimicrobial therapy was 40 +/- 30 weeks. Mean relapse-free followup duration was 50 +/- 50 weeks. CONCLUSIONS: Diabetic foot osteomyelitis was effectively managed with oral antimicrobial therapy with or without limited office debridement in most patients. This regimen may be especially useful in communities where infectious disease specialists and operative resources are limited.

A Competitive Objective Structured Clinical Examination Event to Generate an Objective Assessment of Anesthesiology Resident Skills Development.

Residency programs are charged with teaching, assessing, and documenting resident competency for a multitude of skills throughout the course of residency training. An innovative, competition-based objective structured clinical examination event was designed in our department to objectively assess the skill level of anesthesiology residents. After conducting the identical event for 2 years in postgraduate year 1 (PGY1) and postgraduate year 2 (PGY2) residents, we tested the hypothesis that the event can provide adequate standardization to appropriately document progression in technical and nontechnical skills. Twenty-one residents participated in both events during their PGY1 and PGY2 years: n = 10, 2012/2013, n = 11, 2013/2014. The PGY1 participants in 2012 were retested in 2013 (as PGY2 residents) during an identical event, and their performance was compared as a group and on an individual level. The PGY1 residents in 2013 did the same in 2014. Four workstations were analyzed to determine whether improvement in performance occurred between the PGY1 and the PGY2 years: (1) preoperative assessment, (2) operating room anesthesia station checkout, (3) peripheral IV and endotracheal tube placement, and (4) transfer of care in the postanesthesia care unit. The performances of PGY1 and PGY2 residents were compared. The assessments were performed by anesthesiology faculty using checklists, time to complete task, and Likert scale ratings. Data analysis showed improved technical anesthesia skills (operating room setup, peripheral IV, and endotracheal tube placement) and more complete anesthesia-related information management in the preoperative assessment and postoperative transition of care in the postanesthesia care unit in PGY2 residents compared with the PGY1 performance of the same residents. The described event is a valuable tool for objective assessment of multiple anesthesia skills and possible milestones during residency.

Objective Assessment of Anesthesiology Resident Skills Using an Innovative Competition-Based Simulation Approach.

Residency programs are charged with teaching, assessing, and documenting resident competency for a multitude of skills. Documentation of competency requires demonstrating specific milestones mandated by the Accreditation Council for Graduate Medical Education. Our department designed an innovative, competition-based approach to objectively assess the skill level of postgraduate year 1 residents in performing basic anesthesia-related tasks after 1 month of anesthesiology training. We launched an "Olympic" event to assess requisite skills in an environment of friendly competition. A simulation format was chosen to allow standardized objective assessment of the resident's skill level at an early stage of training, with possible identification of and intervention for skills needing improvement. Our experience may serve as a template for other programs and specialties developing processes for assessing and documenting improvement in skill and competency over the course of residency training.
