Proficiency-based Fundamentals of Laparoscopic Surgery skills training results in durable performance improvement and a uniform certification pass rate.

BACKGROUND: The authors have previously documented a 100% certification pass rate immediately after a proficiency-based skills training curriculum for the Fundamentals of Laparoscopic Surgery (FLS) program. This study aimed to determine the durability of skills acquired after initial training. METHODS: For this study, 21 novice medical students were enrolled in institutional review board (IRB)-approved protocols at two institutions. As previously reported, all the participants successfully completed a structured proficiency-based training curriculum by practicing the five FLS tasks in a distributed fashion over a 2-month period. Pre- and posttesting was conducted, and standard testing metrics were used. The participants were recruited for repeat testing 6 months (retention 1) and 1 year (retention 2) after initial curriculum completion. Of the original 21 students, 15 (10 at University of Texas Southwestern and 5 at Uniformed Services University) were available and agreed to participate. The participants had no additional skills lab training and minimal clinical laparoscopic exposure. RESULTS: None of the 15 participants demonstrated proficiency at the initial pretest (mean score, 146 ± 65), and performance showed significant improvement (p < 0.001) at the posttest (469 ± 20). The participants retained a very high level of performance at retention 1 (437 ± 39; 93% retention of the posttest score) and retention 2 (444 ± 55; 95% retention of the posttest score). Their performance at both retention testing-intervals was sufficient for passing the certification exam (270 cutoff score for passing) with a comfortable margin. There were no significant differences in performance between the two institutions at any time points. CONCLUSION: The proficiency-based FLS skills curriculum reliably results in a high level of skill retention, even in the absence of ongoing simulator-based training or clinical experience. This curriculum is suitable for widespread implementation.

Teaching breaking bad news using mixed reality simulation.

BACKGROUND: Our novel teaching approach involved having students actively participate in an unsuccessful resuscitation of a high fidelity human patient simulator with a gun shot wound to the chest, followed immediately by breaking bad news (BBN) to a standardized patient wife (SPW) portrayed by an actress. METHODS: Brief education interventions to include viewing a brief video on the SPIKES protocol on how to break bad news, a didactic lecture plus a demonstration, or both, was compared to no pretraining by dividing 553 students into four groups prior to their BBN to the SPW. The students then self-assessed their abilities, and were also evaluated by the SPW on 21 items related to appearance, communication skills, and emotional affect. All received cross-over training. RESULTS: Groups were equal in prior training (2 h) and belief that this was an important skill to be learned. Students rated the experience highly, and demonstrated marked improvement of self-assessed skills over baseline, which was maintained for the duration of the 12-wk clerkship. Additionally, students who received any of the above training prior to BBN were rated superior to those who had no training on several communication skills, and the observation of the video seemed to offer the most efficient way of teaching this skill in a time delimited curriculum. CONCLUSION: This novel approach was well received and resulted in improvement over baseline. Lessons learned from this study have enhanced our curricular approach to this vital component of medical education.

Exporting simulation technology to the Philippines: a comparative study of traditional versus simulation methods for teaching intravenous cannulation.

This study examines effectiveness of a donated Laerdal Virtual I.V. simulator when compared with traditional methods of teaching intravenous (IV) cannulation to third year medical students in the Philippines. Forty novice Filipino medical students viewed an instructional video on how to start intravenous lines and were then randomly divided into two groups of twenty. The "Traditional" group observed an IV insertion on an actual patient performed by an experienced practitioner, and then subsequently performed an IV on an actual patient which was videotaped. The "Simulation" group practiced the Virtual I.V. simulator until they successfully completed level three using the "doctor" setting. These students then performed an IV on an actual patient which was videotaped. The videotapes for both groups were reviewed by two pre-trained (Inter-rater reliability of > or =0.84) observers who were blinded to the group using a previously validated checklist for IV insertion. Students trained on the Virtual I.V. showed significantly greater success in successfully starting an IV on an actual patient (40% VS. 15%, p<0.05), decreased constrictive band time (p<.05), increased raw score on the check list (p<.03), and decreased overall time to start an IV (p<.05). The technology was well received but wider application in the non western world is limited by lack of in country company support and the relative expense.

Certification pass rate of 100% for fundamentals of laparoscopic surgery skills after proficiency-based training.

BACKGROUND: The fundamentals of laparoscopic surgery (FLS) program has been extensively validated for use as a high-stakes examination for certification purposes, but optimal methods for its use in skills training have not been described. This study aimed to investigate the feasibility of implementing a proficiency-based FLS skills training curriculum and to evaluate its effectiveness in preparing trainees for certification. METHODS: For this study, 21 novice medical students at two institutions viewed video tutorials, then performed one repetition of the five FLS tasks as a pretest. The pretests were scored using standard testing metrics. The trainees next practiced the tasks over a 2-month period until they achieved proficiency for all the tasks. A modified on-the-fly scoring system based on expert-derived performance was used. The trainees were posttested using the high-stakes examination format. RESULTS: No trainee passed the certification examination at pretesting. The trainees achieved proficiency for 96% of the five tasks during training, which required 9.7 +/- 2.4 h (range, 6-14 h) and 119 +/- 31 repetitions (range, 66-161 repetitions). The trainees rated the proficiency levels as "moderately difficult" (3.0 +/- 0.7 on a 5-point scale) and "highly appropriate" (4.7 +/- 0.1 on a 5-point scale). At posttesting, 100% of the trainees passed the certification examination and demonstrated significant improvement compared with pretesting for normalized score (468 +/- 24 vs 126 +/- 75; p < 0.001), self-rated laparoscopic comfort (89.4% vs 4.8%; p < 0.001), and skill level (3.6 +/- 0.9 vs 1.2 +/- 0.5; p < 0.001, 5-point scale). CONCLUSIONS: This proficiency-based curriculum is feasible for training novices and uniformly allows sufficient skill acquisition for FLS certification. Endorsed by the Society of American Gastrointestinal Endoscopic Surgeons (SAGES), this curriculum is available for use as an optimal method for FLS skills training. More widespread adoption of this curriculum is encouraged.

Combining high-fidelity human patient simulators with a standardized family member: a novel approach to teaching breaking bad news.

Our novel approach to teaching Breaking Bad News (BBN) involves having students actively participate in an unsuccessful resuscitation (mannequin) followed immediately by BBN to a standardized patient wife (SPW) portrayed by an actress. Thirty-nine 3(rd) year medical students completed a questionnaire and then were divided as follows: Group 1 (n=21) received little to no training prior to speaking with the SPW. Group 2 (n =18) received a lecture and practiced for 1 hour in small groups prior to the resuscitation and BBN. Both groups self assessed ability to BBN (p<.0002 & p<.00001), and ability to have a plan (p<.0004 & p <.0003) improved significantly over base line with greater improvement in group 2. Group 2 (pre-trained) students were rated superior by SPW's in several key areas. This novel approach to teaching BBN to 3(rd) year medical students was well received by the students and resulted in marked improvement of self assessed skills over baseline.

Teaching intravenous cannulation to medical students: comparative analysis of two simulators and two traditional educational approaches.

This study examines the effectiveness of two virtual reality simulators when compared with traditional methods of teaching intravenous (IV) cannulation to third year medical students. Thirty-four third year medical students were divided into four groups and then trained to perform an IV cannulation using either CathSim, Virtual I.V., a plastic simulated arm or by practicing IV placement on each other. All subjects watched a five minute training video and completed a cannulation pretest and posttest on the simulated arm. The results showed significant improvement from pretest to posttest in each of the four groups. Students trained on the Virtual I.V. showed significantly greater improvement over baseline when compared with the simulated arm group (p<.026). Both simulators provided at least equal training to traditional methods of teaching, a finding with implications for future training of this procedure to novices.

Immunosuppressants.

This edition of the Med-Psych Drug-Drug Interactions Update begins a change in format. Starting with this column, each column will feature one drug-drug interaction (DDI) topic that will be explored in depth. This edition features DDIs associated with the commonly used immunosuppressants. These drugs are frequently encountered by consultation-liaison psychiatrists in tertiary care settings. Generally, most of these drugs have narrow safety and therapeutic windows; therefore, other drugs that change their serum levels can have deleterious effects. In this review, the DDI profiles of cyclosporine, tacrolimus, sirolimus, and the corticosteroids are explored.
