'Role Model Moments' and 'Troll Model Moments' in Surgical Residency: How Do They Influence Professional Identity Formation?

Introduction: Role models are powerful contributors to residents' professional identity formation (PIF) by exhibiting the values and attributes of the community. While substantial knowledge on different attributes of role models exists, little is known about their influence on residents' PIF. The aim of this study was to explore surgical residents' experiences with role models and to understand how these contribute to residents' PIF. Methods: Adopting a social constructivist paradigm, the authors used a grounded theory approach to develop an explanatory model for residents' experiences with role models regarding PIF. Fourteen surgical residents participated in individual interviews. The authors iteratively performed data collection and analysis, and applied constant comparison to identify relevant themes. Results: Role model behavior is highly situation dependent. Therefore, residents learn through specific 'role model moments'. These moments arise when residents (1) feel positive about a moment, e.g. "inspiration", (2) have a sense of involvement, and (3) identify with their role model. Negative role model moments ('troll model moments') are dominated by negative emotions and residents reject the modeled behavior. Residents learn through observation, reflection and adapting modeled behavior. As a result, residents negotiate their values, strengthen attributes, and learn to make choices on the individual path of becoming a surgeon. Discussion: The authors suggest a nuance in the discussion on role modelling: from 'learning from role models' to 'learning from role model moments'. It is expected that residents' PIF will benefit from this approach since contextual factors and individual needs are emphasized. Residents need to develop antennae for both role model moments and troll model moments and acquire the skills to learn from them. Role model moments and troll model moments are strong catalysts of PIF as residents follow in the footsteps of their role models, yet learn to go their own way.

Lisfranc injuries: fix or fuse? : a systematic review and meta-analysis of current literature presenting outcome after surgical treatment for Lisfranc injuries.

AIMS: This systematic review and meta-analysis was conducted to compare open reduction and internal fixation (ORIF) with primary arthrodesis (PA) in the treatment of Lisfranc injuries, regarding patient-reported outcome measures (PROMs), and risk of secondary surgery. The aim was to conclusively determine the best available treatment based on the most complete and recent evidence available. METHODS: A systematic search was conducted in PubMed, Cochrane Controlled Register of Trials (CENTRAL), EMBASE, CINAHL, PEDro, and SPORTDiscus. Additionally, ongoing trial registers and reference lists of included articles were screened. Risk of bias (RoB) and level of evidence were assessed using the Cochrane risk of bias tools and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) tool. The random and fixed-effect models were used for the statistical analysis. RESULTS: A total of 20 studies were selected for this review, of which 12 were comparative studies fit for meta-analysis, including three randomized controlled trials (RCTs). This resulted in a total analyzed population of 392 patients treated with ORIF and 249 patients treated with PA. The mean differences between the two groups in American Orthopedic Foot and Ankle Society (AOFAS), VAS, and SF-36 scores were -7.41 (95% confidence interval (CI) -13.31 to -1.51), 0.77 (95% CI -0.85 to 2.39), and -1.20 (95% CI -3.86 to 1.46), respectively. CONCLUSION: This is the first study to find a statistically significant difference in PROMs, as measured by the AOFAS score, in favour of PA for the treatment of Lisfranc injuries. However, this difference may not be clinically relevant, and therefore drawing a definitive conclusion requires confirmation by a large prospective high-quality RCT. Such a study should also assess cost-effectiveness, as cost considerations might be decisive in decision-making. Level of Evidence: I Cite this article: Bone Jt Open 2021;2(10):842-849.

Should the Extended Lateral Approach Remain Part of Standard Treatment in Displaced Intra-articular Calcaneal Fractures?

The aim of this study was to evaluate the results of open reduction and internal fixation through the extended lateral approach (ELA) in displaced intra-articular calcaneal fractures and to determine whether this approach should remain part of standard therapy. This retrospective cohort study included 60 patients with 64 displaced intra-articular calcaneal fractures who underwent surgical treatment through the ELA. Outcome measures were the visual analog scale foot and ankle (VAS FA), the American Orthopedic Foot and Ankle Society (AOFAS) score, surgical site infections (SSIs), and reoperations. We determined the AOFAS score for 40 patients with 42 fractures, and 42 patients with 44 fractures completed the VAS FA questionnaire. The mean VAS FA score was 61.0 ± 23.4 and the median AOFAS score was 83 (range 33 to 100), with 55% good to excellent scores. We found 10.9% superficial SSIs successfully treated with antibiotics. In 4.7% of patients a deep SSI was diagnosed, wherefore premature implant removal was necessary. Patients with an SSI did not have significantly lower VAS FA or AOFAS scores than did patients without an SSI (p = .318 and p = .766, respectively). Implant removal in absence of SSIs was necessary in 17 patients because of pain, and 3 patients needed secondary arthrodesis because of persistent pain. We concluded that the ELA proved to be a safe procedure, and moreover the most common complications did not influence the long-term outcomes of patients. However, recent literature demonstrates that less invasive techniques seem to exceed the ELA with respect to wound complications.

Costs of Leaks and Bleeding After Sleeve Gastrectomies.

BACKGROUND: Leaks and bleeding are serious postoperative complications after a sleeve gastrectomy (SG). The objective of the present study was to evaluate the costs of leaks and bleeding after SG. METHODS: A retrospective analysis was conducted of a prospective cohort of primary SGs between August 2006 and September 2013 in a bariatric center. All SGs were performed consistently without reinforcement of the staple line. Abscesses adjacent to the staple line were also regarded as leaks. Data were collected on all diagnostic and therapeutic measures necessary to manage leaks or bleeding, days of hospitalization and parenteral feeding, number of blood products, antibiotics, and additional outpatient department visits. RESULTS: One thousand two hundred sixty one patients underwent a SG. Leaks occurred in 32 (2.5%) and bleeding in 27 (2.1%) patients. Median additional costs for leaks were 9284 (range 1748-125,684) and 4267 (range 1524-40,022) for bleeding. Prolonged hospitalization in the ward and ICU accounted for the majority of costs, 50.3 and 31.4%, respectively, for leaks and 42.0 and 34.8% for bleeding. CONCLUSIONS: These data provide insight into the costs of major complications after SG. A wide range is seen especially due to prolonged hospitalization in the ward and ICU. High costs are an additional argument to reduce complication rate. These data should be considered when analyzing the cost-effectiveness of staple line reinforcement.

A comparative analysis of pediatric uroflowmetry curves.

AIMS: This study was conducted to try to objectify assessment of pediatric uroflowmetry curves. MATERIALS AND METHODS: Nine professionals in pediatric incontinence care judged 480 pediatric uroflows. On a 1-5 scale, where 1 = anomalous and 5 = normal, uroflows were assessed on four items: staccato, interrupted, flow time and obstruction. Eighty uroflows were re-evaluated for intra-observer agreement. After staccato and interrupted flow had been defined more sharply, another 100 uroflows were analyzed. Cohen's Kappa test for nominally classified data was applied to assess agreement. Kappa value of <0.20 denoted poor agreement, 0.21-0.40 fair, 0.41-0.60 moderate, 0.61-0.80 substantial and 0.81-1.0 perfect or almost perfect agreement. A second analysis was done using a 3 point scale, anomalous, intermediate and normal. RESULTS: For interobserver agreement, Kappas were 0.45 for staccato flow, 0.67 for interrupted, 0.59 for flow time, and 0.66 for obstruction. For intra-observer agreement, Kappas were 0.47 for staccato, 0.65 for interrupted, 0.55 for flow time, and 0.65 for obstruction. On a three-point scale, anomalous, intermediate, and normal, interobserver agreement was equal to 0.80 or above. In the second 100 uroflows, the interobserver agreement Kappas were 0.44 for staccato, 0.95 for interrupted, 0.71 for flow time and 0.73 for obstruction. CONCLUSION: Moderate to substantial agreement on uroflowmetry curves can be reached, except for staccato. Agreement increases if staccato and interrupted flows are defined more sharply. Staccato is defined as three or more peaks and troughs of more than the square root of maximal flow without touching 0, whereas interrupted flow needs at least one 0 passage. In a normal, uninterrupted uroflow, flow time is under 15 sec.
