RESUMO

BACKGROUND: The COVID-19 pandemic in parallel with concerns about bias in grading resulted in many medical schools adopting pass/fail clinical grading and relying solely on narrative assessments. However, narratives often contain bias and lack specificity. The purpose of this project was to develop asynchronous faculty development to rapidly educate/re-educate > 2000 clinical faculty spread across geographic sites and clinical disciplines on components of a well-written narrative and methods to minimize bias in the assessment of students. METHODS: We describe creation, implementation, and pilot data outcomes for an asynchronous faculty development curriculum created by a committee of volunteer learners and faculty. After reviewing the literature on the presence and impact of bias in clinical rotations and ways to mitigate bias in written narrative assessments, the committee developed a web-based curriculum using multimedia learning theory and principles of adult learning. Just-in-time supplemental materials accompanied the curriculum. The Dean added completion of the module by 90% of clinical faculty to the department chairperson's annual education metric. Module completion was tracked in a learning management system, including time spent in the module and the answer to a single text entry question about intended changes in behavior. Thematic analysis of the text entry question with grounded theory and inductive processing was used to define themes of how faculty anticipate future teaching and assessment as a result of this curricula. OUTCOMES: Between January 1, 2021, and December 1, 2021, 2166 individuals completed the online module; 1820 spent between 5 and 90 min on the module, with a median time of 17 min and an average time of 20.2 min. 15/16 clinical departments achieved completion by 90% or more faculty. Major themes included: changing the wording of future narratives, changing content in future narratives, and focusing on efforts to change how faculty teach and lead teams, including efforts to minimize bias. CONCLUSIONS: We developed a faculty development curriculum on mitigating bias in written narratives with high rates of faculty participation. Inclusion of this module as part of the chair's education performance metric likely impacted participation. Nevertheless, time spent in the module suggests that faculty engaged with the material. Other institutions could easily adapt this curriculum with provided materials.

RESUMO

BACKGROUND: Clinical education across the professions is challenged by a lack of recognition for faculty and pressure for patient throughput and revenue generation. These pressures may reduce direct observation of patient care provided by students, a requirement for both billing student-involved services and assessing competence. These same pressures may also limit opportunities for interprofessional education and collaboration. METHODS: An interprofessional group of faculty collaborated in a sequential quality improvement project to identify the best patients and physical location for a student teaching clinic. Patient chief complaint, use of resources, length of stay, estimated severity of illness and student participation and evaluation of the clinic was tracked. RESULTS: Clinic Optimization and Patient Care: Five hundred and thirty-two emergency department (ED) patients were seen in the first 19 months of the clinic. A clinic located near the ED allowed for patients with higher emergency severity index and greater utilization of imaging. Patients had similar or lower lengths of stay and higher satisfaction than patients who remained in the ED (p < 0.0001). In the second clinic location, from October 2016-June 2019, 644 patients were seen with a total of 667 concerns; the most common concern was musculoskeletal (50.1%). Student Interprofessional Experience: A total of 991 students participated in the clinic: 68.3% (n = 677) medical students, 10.1% (n = 100) physician assistant students, 9.7% (n = 96) undergraduate nursing students, 9.1% (n = 90) physical therapy students, and 2.8% (n = 28) nurse practitioner students. The majority (74.5%, n = 738) of student participants worked with students from other professions. More than 90% of students reported that faculty set a positive learning environment respectful of students. However, 20% of students reported that faculty could improve provision of constructive feedback. Direct Observation: Direct observation of core entrustable professional activities for medical students was possible. Senior medical students were more likely to be observed generating a differential diagnosis or management plan than first year medical students. CONCLUSIONS: Creation of a DOCENT clinic in the emergency department provided opportunities for interprofessional education and observation of student clinical skills, enriching student experience without compromising patient care.

RESUMO

BACKGROUND: Medical education program evaluation allows for curricular improvements to both Undergraduate (UME) and Graduate Medical Education (GME). UME programs are left with little more than match rates and self-report to evaluate success of graduates in The Match. OBJECTIVE: This manuscript shares a novel method of program evaluation through a systematic assessment of Match outcomes. DESIGN: Surveys were developed and distributed to Program Training Directors (PTDs) at our institution to classify residency programs into which our UME graduates matched using an ordinal response scale and open-ended responses. Outcomes-based measures for UME graduates were collected and analyzed. The relationship between PTD survey data and UME graduates' outcomes were explored. Open-ended response data were qualitatively analyzed using iterative cycles of coding and identifying themes. RESULTS: The PTD survey response rate was 100%. 71% of our graduates matched to programs ranked as 'elite' (36%) or 'top' (35%) tier. The mean total number of 'Honors' grades achieved by UME graduates was 2.6. Data showed that graduates entering elite and top GME programs did not consistently earn Honors in their associated clerkships. A positive correlation was identified between USMLE Step 1 score, number of honors, and residency program rankings for a majority of the programs. Qualitative analysis identified research, faculty, and clinical exposure as necessary characteristics of 'elite' programs:. Factors considered by PTDs in the rating of programs included reputation, faculty, research, national presence and quality of graduates. CONCLUSIONS: This study describes a novel outcomes-based method of evaluating the success of UME programs. Results provided useful feedback about the quality of our UME program and its ability to produce graduates who match in highly-regarded GME programs. The findings from this study can benefit Clerkship Directors, Student Affairs and Curriculam Deans, and residency PTDs as they help students determine their competitiveness forspecialties and specific residency programs.

RESUMO

PURPOSE: To evaluate low- vs high-dose plaque brachytherapy for juxtapapillary choroidal melanoma. DESIGN: Retrospective interventional case series. METHODS: Setting: Single institution. STUDY POPULATION: Forty-seven patients with juxtapapillary choroidal melanoma. INTERVENTION: Iodine-125 plaque brachytherapy. Eyes were divided into apex low-dose (LD) and high-dose (HD) groups (≤ or > median apex dose 84.35 Gy). Main outcome measures were time to distant failure, local failure, death, enucleation, radiation retinopathy, optic neuropathy, and best-corrected visual acuity (BCVA). RESULTS: Freedom from distant failure rates were 96% and 95% in apex LD and HD groups at 5 years and 77% and 95% at 10 years, respectively (P = .84). Freedom from local failure rates were 90% in the apex LD group vs 89% in the HD group at 5 and 10 years (P = .96). Apex LD and HD groups did not differ for time to death or enucleation. Five- and 10-year freedom from radiation retinopathy and optic neuropathy rates were higher in the apex LD than HD group. Loss of ≥3 BCVA lines, final BCVA 20/40 or better, and final BCVA 20/200 or worse were more favorable in the 5 mm LD compared to HD group. Visual acuity outcomes did not differ between apex LD and HD groups. CONCLUSIONS: Low-dose iodine-125 plaque brachytherapy (67.5-81 Gy at tumor apex) provides safe and effective tumor control for juxtapapillary choroidal melanoma and may be associated with reduced radiation toxicity. Larger trials are needed to determine the optimal therapeutic dose for juxtapapillary choroidal melanoma.

RESUMO

PURPOSE: To report the prevalence of anisometropia at age 5 years after unilateral intraocular lens (IOL) implantation in infants. DESIGN: Prospective randomized clinical trial. METHODS: Fifty-seven infants in the Infant Aphakia Treatment Study (IATS) with a unilateral cataract were randomized to IOL implantation with an initial targeted postoperative refractive error of either +8 diopters (D) (infants 28 to <48 days of age) or +6 D (infants 48-210 days of age). Anisometropia was calculated at age 5 years. Six patients were excluded from the analyses. RESULTS: Median age at cataract surgery was 2.2 months (interquartile range [IQR], 1.2, 3.5 months). The mean age at the age 5 years follow-up visit was 5.0 ± 0.1 years (range, 4.9-5.4 years). The median refractive error at the age 5 years visit of the treated eyes was -2.25 D (IQR -5.13, +0.88 D) and of the fellow eyes +1.50 D (IQR +0.88, +2.25). Median anisometropia was -3.50 D (IQR -8.25, -0.88 D); range -19.63 to +2.75 D. Patients with glaucoma in the treated eye (n = 9) had greater anisometropia (glaucoma, median -8.25 D; IQR -11.38, -5.25 D vs no glaucoma median -2.75; IQR -6.38, -0.75 D; P = .005). CONCLUSIONS: The majority of pseudophakic eyes had significant anisometropia at age 5 years. Anisometropia was greater in patients that developed glaucoma. Variability in eye growth and myopic shift continue to make refractive outcomes challenging for IOL implantation during infancy.

RESUMO

PURPOSE: To report differences in visual acuities among patients with Coats' disease who sought treatment at a tertiary care university-based practice. DESIGN: Single-center retrospective cohort study. PARTICIPANTS: Patients with Coats' disease diagnosed clinically, angiographically, or both from 1995 through 2015. METHODS: Patients were divided into 2 groups based on date of presentation: decade 1 (1995-2005) and decade 2 (2006-2015). MAIN OUTCOME MEASURES: Visual acuity (VA). RESULTS: Thirty-nine eyes of 39 patients were included with 19 eyes presenting in decade 1 and 20 eyes presenting in decade 2. Three patients demonstrated bilateral disease, but only the worse eye was included for analysis. Forty-seven percent of eyes in decade 1 demonstrated advanced stages of disease (stage 3B or worse) compared with 20% of eyes in decade 2. There was a trend for the mean initial presenting VA (±standard deviation) for decade 1 eyes to be worse (2.05±1.29 logarithm of the minimum angle of resolution [logMAR]) than for decade 2 eyes (1.45±0.99 logMAR; P = 0.1). From initial to final follow-up visit, mean VA also worsened for decade 1 eyes (P = 0.03), but remained stable for decade 2 eyes (P = 1.0). At the end of follow-up, there was a trend for mean VA for decade 1 eyes (2.28±1.17 logMAR) to be worse than for decade 2 eyes (1.60±1.15 logMAR; P = 0.07). Eight eyes were observed initially in decade 1 compared with 1 eye in decade 2, and only 1 of the observed eyes (in decade 2) developed painful glaucoma requiring enucleation. Decade 2 eyes had a higher average number of procedures per eye (6.5±4.9) compared with decade 1 eyes (1.4±1.7; P < 0.001). CONCLUSIONS: The earlier presentation of disease in decade 2 suggests improvements in disease detection over time. Furthermore, there was a trend for eyes to have better final VA in this decade. This is due to a combination of factors, including earlier presentation of disease, fewer eyes being observed without treatment, and eyes, when treated, receiving a higher number of procedures.

RESUMO

PURPOSE: To report the myopic shift at 5 years of age after cataract surgery with intraocular lens (IOL) implantation for infants enrolled in the Infant Aphakia Treatment Study (IATS). METHODS: Refractions were performed at 1 month and every 3 months postoperatively until age 4 years and then at ages 4.25, 4.5, and 5 years. The change in refraction over time was estimated by linear mixed model analysis. RESULTS: Intraocular lens implantation was completed in 56 eyes; 43 were analyzed (median age, 2.4 months; range, 1.0-6.8 months). Exclusions included 11 patients with glaucoma, 1 patient with Stickler syndrome, and 1 patient with an IOL exchange at 8 months postoperatively. The mean rate of change in a myopic direction from 1 month after cataract surgery to age 1.5 years was 0.35 diopters (D)/month (95% confidence interval [CI], 0.29-0.40 D/month); after age 1.5 years, the mean rate of change in a myopic direction was 0.97 D/year (95% CI, 0.66-1.28 D/year). The mean refractive change was 8.97 D (95% CI, 7.25-10.68 D) at age 5 years for children 1 month of age at surgery and 7.22 D (95% CI, 5.54-8.91 D) for children 6 months of age at surgery. The mean refractive error at age 5 years was -2.53 D (95% CI, -4.05 to -1.02). CONCLUSIONS: After IOL implantation during infancy, the rate of myopic shift occurs most rapidly during the first 1.5 years of life. Myopic shift varies substantially among patients. If the goal is emmetropia at age 5 years, then the immediate postoperative hypermetropic targets should be +10.5 D at 4 to 6 weeks and +8.50 D from 7 weeks to 6 months. However, even using these targets, it is likely that many children will require additional refractive correction given the high variability of refractive outcomes.

RESUMO

Fulminant idiopathic intracranial hypertension (FIIH) is a subtype of idiopathic intracranial hypertension (IIH) characterized by rapid, severe, progressive vision loss. Surgical intervention is often performed either as a cerebrospinal fluid (CSF) shunt procedure or an optic nerve sheath fenestration or, at times, both. These surgical procedures carry a significant risk of morbidity and failure. We present 2 patients in whom a temporary lumbar drain was successfully used in the management of medically undertreated pediatric FIIH, and circumvented the need for surgical intervention.

RESUMO

PURPOSE OF REVIEW: The basic procedure of pediatric cataract surgery has not dramatically changed over the past few years. Recent multicenter study results along with technological innovations, however, have increased our understanding and armamentarium of techniques and devices used to improve outcomes. RECENT FINDINGS: We review surgical techniques that have been recently applied to the management of pediatric cataracts and describe newer intraocular lenses that have become available for use in the pediatric population. The 5-year results of the Infant Aphakia Treatment Study, including visual outcomes and complications, as well as other studies comparing intraocular lens implants with contact lenses for infants have shaped our management of congenital cataract. We also discuss how ocular imaging with optical coherence tomography has enhanced our understanding of the microstructural effects on pediatric eyes after cataract surgery and touch on other future innovations. SUMMARY: We review updates in the management of congenital cataract, which remains a major cause of preventable childhood blindness.

RESUMO

PURPOSE: To compare the rate of refractive growth (RRG) between aphakic eyes and pseudophakic eyes in the Infant Aphakia Treatment Study (IATS). SETTING: Twelve clinical sites across the United States. DESIGN: Randomized clinical trial. METHODS: Patients randomized to unilateral cataract extraction with contact lens correction versus intraocular lens (IOL) implantation in the IATS had their rate of refractive growth (RRG3) calculated based on the change in refraction from the 1-month postoperative examination to age 5 years. The RRG3 is a logarithmic formula designed to calculate the RRG in children. Two-group t tests were used to compare the mean refractive growth between the contact lens group and IOL group and outcomes based on age at surgery and visual acuity. RESULTS: Longitudinal refractive data were studied for 108 of 114 patients enrolled in the IATS (contact lens group, n = 54; IOL group, n = 54). The mean RRG3 was similar in the contact lens group (-18.0 diopter [D] ± 11.0 [SD]) and the IOL group (-19.0 ± 9.0 D) (P = .49). The RRG3 value was not correlated with age at cataract surgery, glaucoma status, or visual outcome in the IOL group. In the aphakia group, only visual outcome was correlated with refractive growth (P = .01). CONCLUSIONS: Infants' eyes had a similar rate of refractive growth after unilateral cataract surgery whether or not an IOL was implanted. A worse visual outcome was associated with a higher RRG in aphakic, but not pseudophakic, eyes. FINANCIAL DISCLOSURE: None of the authors has a financial or proprietary interest in any material or method mentioned.

RESUMO

PURPOSE: To compare the in vitro characteristics of Tenon's capsule fibroblasts from children and adults that may be relevant to filtration surgery success. METHODS: Fibroblast cell lines derived from 5 young (median patient age, 2.4 years) and 7 old (median patient age, 71 years) discarded Tenon's capsule surgical specimens were used at early passage (P2-P3). Fibroblasts were plated at "high" (10(4)cells/cm(2)) or "low" density (10(3)cells/cm(2)) and harvested at days 0-14, for growth curve and doubling time comparisons. Migration was measured using a wound model (confluent monolayers ± 5-fluorouracil [5-FU] over 1-96 hours). Collagen synthesis was measured as secreted hydroxyproline/24 hours from confluent monolayers. RESULTS: At low density, "young" fibroblasts achieved higher cell numbers at confluence (day 14) compared with "old": 158 ± 35 versus 105 ± 12 × 10(3)cells/cm(2) (P = 0.0034). Mean doubling time for young versus old was similar at low density plating: 20.95 ± 1.55 versus 22.37 ± 2.09 hours (P = 0.26). It was shorter, however, for young versus old at high-density plating: 42.11 ± 6.01 versus 54.26 ± 4.24 hours (P = 0.0051). Wound closure rates were similar for young versus old cells (4 lines for each group) with and without 5-FU. Collagen synthesis was similar for young and old (4 lines for each group). CONCLUSIONS: Although young fibroblasts reached higher density than old at confluence and had shorter doubling times at high-density plating, wound closure/migration and collagen synthesis rates were similar. Despite the preliminary nature of this study (few specimens, limited cell features explored), factors besides those intrinsic to the fibroblasts themselves likely mediate the more rapid healing/scarring after glaucoma filtration surgery in children.

RESUMO

PURPOSE: To evaluate a clinical observation that prepubertal children with idiopathic intracranial hypertension (IIH) have low cerebrospinal fluid (CSF) protein levels compared to healthy children and pubertal patients with IIH. METHODS: The medical records of prepubertal and pubertal IIH patients and controls seen in the pediatric neuro-ophthalmology clinic at Duke between 2003 and 2013 were retrospectively reviewed. The control group consisted of children who had normal intracranial pressure on lumbar puncture performed to evaluate for headaches or anomalous-looking optic nerves. The records were analyzed with attention to demographic characteristics, clinical presentation, course, and lumbar puncture results. RESULTS: A total of 23 prepubertal children with IIH (age range, 0.75-13 years), 16 pubertal patients with IIH (age range, 13-21 years), and 12 controls (age range 3-14 years) were included. CSF analysis revealed that prepubertal children with IIH had significantly lower CSF protein levels (17.3 ± 5.7 mg/dL) compared to pubertal subjects with IIH (23.4 ± 8.4 mg/dL; P = 0.019) or healthy controls (23.5 ± 6.4 mg/dL; P = 0.011). Furthermore, 9 of 23 prepubertal IIH patients (39%) had abnormally low CSF protein level (<15 mg/dL), compared to zero pubertal IIH patients (P = 0.005) and zero controls (P = 0.015). Acetazolamide increased CSF protein level in 100% of patients who underwent repeat lumbar puncture after starting the medication (average increase, 10.3 ± 6.6 mg/dL). CONCLUSIONS: Low CSF protein level may have diagnostic utility as a biomarker for prepubertal IIH. Furthermore, this finding suggests that some cases of prepubertal IIH may be caused by CSF overproduction rather than decreased CSF resorption.

RESUMO

PURPOSE: To compare rates and severity of complications between infants undergoing cataract surgery with and without intraocular lens (IOL) implantation. DESIGN: Prospective randomized clinical trial. METHODS: A total of 114 infants were enrolled in the Infant Aphakia Treatment Study, a randomized, multi-center (12) clinical trial comparing the treatment of unilateral aphakia in patients under 7 months of age with a primary IOL implant or contact lens. The rate, character, and severity of intraoperative complications, adverse events, and additional intraocular surgeries during the first 5 postoperative years in the 2 groups were examined. RESULTS: There were more patients with intraoperative complications (28% vs 11%, P = .031), adverse events (81% vs 56%, P = .008), and more additional intraocular surgeries (72% vs 16%, P < .0001) in the IOL group than in the contact lens group. However, the number of patients with adverse events in the contact lens group increased (15 to 24) in postoperative years 2-5 compared to the first postoperative year, while it decreased (44 to 14) in years 2-5 compared to the first postoperative year in the IOL group. If only one half of the patients in the contact lens (aphakic) group eventually undergo secondary IOL implantation, the number of additional intraocular surgeries in the 2 groups will be approximately equal. CONCLUSION: The increased rate of complications, adverse events, and additional intraocular surgeries associated with IOL implantation in infants <7 months of age militates toward leaving babies aphakic if it is considered likely that the family will be successful with contact lens correction.

RESUMO

IMPORTANCE: The efficacy and safety of primary intraocular lens (IOL) implantation during early infancy is unknown. OBJECTIVE: To compare the visual outcomes of patients optically corrected with contact lenses vs IOLs following unilateral cataract surgery during early infancy. DESIGN, SETTING, AND PARTICIPANTS: The Infant Aphakia Treatment Study is a randomized clinical trial with 5 years of follow-up that involved 114 infants with unilateral congenital cataracts at 12 sites. A traveling examiner assessed visual acuity at age 4.5 years. INTERVENTIONS: Cataract surgery with or without primary IOL implantation. Contact lenses were used to correct aphakia in patients who did not receive IOLs. Treatment was determined through random assignment. MAIN OUTCOMES AND MEASURES: HOTV optotype visual acuity at 4.5 years of age. RESULTS: The median logMAR visual acuity was not significantly different between the treated eyes in the 2 treatment groups (both, 0.90 [20/159]; P = .54). About 50% of treated eyes in both groups had visual acuity less than or equal to 20/200. Significantly more patients in the IOL group had at least 1 adverse event after cataract surgery (contact lens, 56%; IOL, 81%; P = .02). The most common adverse events in the IOL group were lens reproliferation into the visual axis, pupillary membranes, and corectopia. Glaucoma/glaucoma suspect occurred in 35% of treated eyes in the contact lens group vs 28% of eyes in the IOL group (P = .55). Since the initial cataract surgery, significantly more patients in the IOL group have had at least 1 additional intraocular surgery (contact lens, 21%; IOL, 72%; P < .001). CONCLUSIONS AND RELEVANCE: There was no significant difference between the median visual acuity of operated eyes in children who underwent primary IOL implantation and those left aphakic. However, there were significantly more adverse events and additional intraoperative procedures in the IOL group. When operating on an infant younger than 7 months of age with a unilateral cataract, we recommend leaving the eye aphakic and focusing the eye with a contact lens. Primary IOL implantation should be reserved for those infants where, in the opinion of the surgeon, the cost and handling of a contact lens would be so burdensome as to result in significant periods of uncorrected aphakia.

RESUMO

PURPOSE: To investigate, in the treatment of uveal melanomas, how tumor control, radiation toxicity, and visual outcomes are affected by the radiation dose at the tumor apex. METHODS AND MATERIALS: A retrospective review was performed to evaluate patients treated for uveal melanoma with (125)I plaques between 1988 and 2010. Radiation dose is reported as dose to tumor apex and dose to 5 mm. Primary endpoints included time to local failure, distant failure, and death. Secondary endpoints included eye preservation, visual acuity, and radiation-related complications. Univariate and multivariate analyses were performed to determine associations between radiation dose and the endpoint variables. RESULTS: One hundred ninety patients with sufficient data to evaluate the endpoints were included. The 5-year local control rate was 91%. The 5-year distant metastases rate was 10%. The 5-year overall survival rate was 84%. There were no differences in outcome (local control, distant metastases, overall survival) when dose was stratified by apex dose quartile (<69 Gy, 69-81 Gy, 81-89 Gy, >89 Gy). However, increasing apex dose and dose to 5-mm depth were correlated with greater visual acuity loss (P=.02, P=.0006), worse final visual acuity (P=.02, P<.0001), and radiation complications (P<.0001, P=.0009). In addition, enucleation rates were worse with increasing quartiles of dose to 5 mm (P=.0001). CONCLUSIONS: Doses at least as low as 69 Gy prescribed to the tumor apex achieve rates of local control, distant metastasis-free survival, and overall survival that are similar to radiation doses of 85 Gy to the tumor apex, but with improved visual outcomes.
