Perioperative self-reflection among surgical residents.

BACKGROUND: We studied prevalence and predictors of meaningful self-reflection among surgical residents and with prompting/structured interventions, sought to improve/sustain resident skills. METHODS: Residents from six programs recorded 1032 narrative self-reflective comments (120 residents), using a web-based platform. If residents identified something learned or to be improved, self-reflection was deemed meaningful. Independent variables PGY level, resident/surgeon gender, study site/Phase1: July2014-August2015 vs. Phase2: September2015-September2016) were analyzed. RESULTS: Meaningful self-reflection was documented in 40.6% (419/1032) of entries. PGY5's meaningfully self-reflected less than PGY1-4's, 26.1% vs. 49.6% (p = 0.002). In multivariate analysis, resident narratives during Phase 2 were 4.7 times more likely to engage in meaningful self-reflection compared to Phase1 entries (p < 0.001). Iterative changes during Phase2 showed a 236% increase in meaningful self-reflection, compared to Phase1. CONCLUSIONS: Surgical residents uncommonly practice meaningful self-reflection, even when prompted, and PGY5/chief residents reflect less than more junior residents. Substantial/sustained improvements in resident self-reflection can occur with both training and interventions.

Do female surgeons learn or teach differently?

BACKGROUND: Gender and/or gender-stereotypes might influence surgical education. We hypothesized that female surgeons might focus their learning and teaching differently from male surgeons. METHODS: Residents and surgeons (multi-institutional) individually recorded preoperatively discussed learning objectives (LO) for matching cases. Narratives were classified as knowledge-based, skill-based, or attitude-based. Multinomial logistic regression analyses, LO = dependent variable; independent variables = resident/surgeon gender, PGY level, timing of entry-to-procedure date, and quarters-of-year. RESULTS: 727 LOs from 125 residents (41% female) and 49 surgeons (20% female) were classified. Female residents were 1.4 times more likely to select knowledge over skill. With female surgeons, residents were 1.6 and 2.1 times more likely to select knowledge over skill and attitude over skill than if the surgeon was male. PGY 4/5 residents chose attitude-based LOs over junior residents. CONCLUSION: Resident, surgeon gender and year-of-training influence learning objectives. Whether this reflects gender stereotyping by residents or differences in attending teaching styles awaits further exploration.

A taxonomy of perioperative surgical learning: Trending resident skill acquisition.

BACKGROUND: Resident and curriculum evaluation require tracking surgical resident operative performance, yet what and when to measure remains unclear. METHODS: From a multi-institutional database, we reviewed 611 resident/surgeon-paired assessments of ACGME Milestones and modified OPRS ratings for different cases and postgraduate years. RESULTS: Faculty Milestone ratings increased with each PGY (p=<0.001) and correlated with resident self-ratings (ICC = 0.83). Mean OPRS scores increased in small increments with substantial intra-year variability. Progression among individual OPRS subcategories was not apparent from more global analyses. Interestingly, male faculty offered lower ratings than female faculty. CONCLUSIONS: Milestones and modified mean OPRS ratings suggest residents are learning, yet lack sufficient discrimination for promotion or curricular analysis. Differential progression through OPRS subcategories suggests a taxonomy of surgical learning that can be tailored to focus on different skills at each point in the training continuum. The effect of faculty gender on resident ratings awaits further study.

Impact of objectively assessing surgeons' teaching on effective perioperative instructional behaviors.

IMPORTANCE: Advancing surgical technology and decreasing resident learning hours have limited exposure to perioperative training, necessitating more effective and efficient perioperative teaching by faculty surgeons. Participation in collaborative efforts and process improvement can change behaviors and enhance teaching. OBJECTIVES: To promote deliberate teaching of residents, change resident perception of their teachers, and produce sustainable improvements by objectively measuring surgeons' perioperative teaching performance. DESIGN, SETTING, AND PARTICIPANTS: This 3-phase observational study of surgeons' perioperative teaching behaviors included university-based surgeons, general surgery residents, and preclinical student observers and involved elective cases at a 600+ bed tertiary hospital. Initially, we measured teaching behaviors by surgeons unaware of study objectives, provided aggregate and confidential individual feedback, and developed standardized preoperative briefings and postoperative debriefings. Phase 2 applied a deliberate teaching model and reinforced behaviors with continuous process improvement efforts (Plan, Do, Check, Act) and repeat observations. Phase 3 used resident prompts to enhance teaching behaviors and demonstrate sustainability. Resident surveys conducted 3 times assessed perceptions of deliberate guidance by faculty when compared with national benchmarks. INTERVENTIONS: Introduction of deliberate faculty preprocedural focusing and postprocedural reinforcement to facilitate resident learning. MAIN OUTCOMES AND MEASURES: More frequent and complete perioperative teaching by faculty and the perception of enhanced teaching by residents. RESULTS: Faculty more commonly and more completely performed the 10-step preoperative briefings and postoperative debriefings (P < .001) during phase 2 (250% improvement over baseline). Intraoperative teaching styles significantly improved and residents' survey-reported assessments of faculty teaching improved over national data for describing procedural steps (P = .02) and requests for resident self-evaluation (P = .006). CONCLUSIONS AND RELEVANCE: Objective recording of teaching behavior frequency motivated adoption of deliberate guided teaching behaviors by surgeons, resulting in both subjective reports by residents of more frequent teaching and objective recording of parallel improvements. A deliberate focus on objectively assessing surgeon educators' periprocedural teaching may motivate improved teaching.

Use of gold mill tailings in making bricks: a feasibility study.

Mill tailings dumps at Kolar Gold Fields, Karnataka, are creating environmental problems. One of the solutions to these problems is to use the mill tailings for some useful purpose. This study examined the possibility of making bricks from the mill tailings with some additives in laboratory experiments. Samples of the mill tailings and the additives were analysed for particle size distribution, Atterberg limits and specific gravity. The plasticity index of the mill tailings being zero, they could not be used directly for making bricks. Therefore some additives that had plasticity or binding properties were mixed with the mill tailings. Ordinary Portland cement, black cotton soils and red soils were selected as additives. Each of the additives was mixed separately with the mill tailings in different proportions by weight and a large number of bricks were prepared using metallic moulds. The bricks were termed as cement-tailings bricks or soil-tailings bricks, depending on the additives used. The cement-tailings bricks were cured for different periods and their corresponding compressive strengths were determined. The bricks with 20% of cement and 14 days of curing were found to be suitable. The soil-tailings bricks were sun-dried and then fired in a furnace at different temperatures. The quality of bricks was assessed in terms of linear shrinkage, water absorption and compressive strength. The cost analysis revealed that cement-tailings bricks would be uneconomical whereas the soil-tailings bricks would be very economical.
