Less is more: creation and validation of a novel, affordable suturing simulator for anorectal surgery.

BACKGROUND: Duty hour restrictions have increased the role of simulation in surgical education. A simulation that recreates the unique visual, anatomic, and ergonomic challenges of anorectal surgery has yet to be described. The aim of this study was to develop a low-cost, low-fidelity anorectal surgery simulator and provide validity evidence for the model. METHODS: A novel, low-fidelity simulator was constructed, and anorectal surgery workshops were implemented for general surgery interns at a single institution. Face and content validity were assessed with separate questionnaires using a 5-point Likert scale. Participants performed a simulated hemorrhoid excision with longitudinal wound closure, and transverse wound closure. Time-to-task completion and quality of suturing/knot tying were evaluated by a blinded observer to assess construct validity. RESULTS: Material cost was US $11 per simulator. We recruited 20 first-year surgery residents (novices) and 4 practicing colorectal surgeons (experts), and conducted 3 workshops in 2014-2016. All face and content validity measures achieved a median score greater than 4 (range 4.0-5.0). Time-to-task completion was significantly lower in the expert cohort (hemorrhoid excision with longitudinal wound closure: 195 vs. 477 s and transverse closure: 79 vs. 192 s, p < 0.001 for both). Suturing and knot-tying scores were significantly higher in the expert cohort for both tasks (p < 0.05 for all comparisons). CONCLUSIONS: Our low-fidelity, low-cost anorectal surgery model demonstrated evidence of face, content, and construct validity. We believe that this simulator could be a useful instrument in the education of junior surgical trainees and will allow residents to obtain proficiency in anorectal suturing tasks in conjunction with traditional surgical training.

Social media engagement amongst 2017 colorectal surgery Tripartite Meeting attendees: updates on contemporary social media use.

AIM: Engagement by medical professionals with social media (SM) is increasing. Variation is noted in engagement between SM platforms and between surgical specialities and geographical regions. We aimed to study SM engagement by colorectal surgeons attending an international conference. METHOD: Surgeons were identified from the delegate list of the 2017 Annual Meeting of the American Society of Colon and Rectal Surgeons (ASCRS) and Tripartite Meeting (Seattle, Washington, USA). Delegates were searched on Twitter and LinkedIn for the presence of a matching profile. SM presence, activity, gender and geographical region were analysed. RESULTS: Two hundred and seventy (13.2%) surgeons had Twitter accounts and 994 (44.3%) had LinkedIn profiles. UK surgeons were more likely to be on Twitter than surgeons from elsewhere (23.4% vs 12.7%, P = 0.0072). Significant variation in SM membership between each geographical region was noted, with usage rates for Twitter of 18.1% in Europe, 14.4% in North America, 12.9% in South America, 4.3% in Oceania, 3.7% in Asia and 0% in Africa. A similar picture for LinkedIn is seen. The #ASCRS17 meeting saw the highest participation of users to date (979 participants, over 7000 individual tweets and nearly 14 million impressions). CONCLUSION: SM engagement by colorectal surgeons continues to increase. Significant geographical variation is noted, suggesting that SM's unique potential for education and networking may not yet be widely appreciated globally. Future work should include further analysis into tweet contents to gain insights and optimize the use of SM as an educational adjunct.

Treatment-Based Three-Dimensional Classification and Management of Anorectal Infections.

This article provides a current overview on clinical anatomy, pathophysiology, workup and surgical management of anorectal abscesses. Based on the three-dimensional nature of anorectal abscesses, a novel treatment-based classification is proposed. It examines the basis of a philosophic shift from simple drainage to concomitant definitive treatment of abscesses and their underlying primary fistulous trajectories. Complications are discussed specifically in this context.

Cost of practice in a tertiary/quaternary referral center: is it sustainable?

BACKGROUND: Third-party payers are moving toward a bundled care payment system. This means that there will need to be a warranty cost of care-where the cost of complexity and complication rates is built into the bundled payment. The theoretical benefit of this system is that providers with lower complication rates will be able to provide care with lower warranty costs and lower overall costs. This may also result in referring riskier patients to tertiary or quaternary referral centers. Unless the payment model truly covers the higher cost of managing such referred cases, the economic risk may be unsustainable for these centers. METHODS: We took the last seven patients that were referred by other surgeons as "too high risk" for colectomy at other centers. A contribution margin was calculated using standard Medicare reimbursement rates at our institution and cost of care based on our administrative database. We then recalculated a contribution margin assuming a 3 % reduction in payment for a higher than average readmission rate, like that which will take effect in 2014. Finally, we took into account the cost of any readmissions. RESULTS: Seven patients with diagnosis related group (DRG) 330 were reviewed with an average age of 66.8 ± 16 years, American Society of Anesthesiologists score 2.3 ± 1.0, body mass index 31.6 ± 9.8 kg/m(2) (range 22-51 kg/m(2)). There was a 57 % readmission rate, 29 % reoperation rate, 10.8 ± 7.7 day average initial length of stay with 14 ± 8.6 day average readmission length of stay. Forty-two percent were discharged to a location other than home. Seventy-one percent of these patients had Medicare insurance. The case mix index was 2.45. Average reimbursement for DRG 330 was $17,084 (based on Medicare data) for our facility in 2012, with the national average being $12,520. The total contribution margin among all cases collectively was -$19,122 ± 13,285 (average per patient -$2,731, range -$21,905-$12,029). Assuming a 3 % reimbursement reduction made the overall contribution margin -$22,122 ± 13,285 (average -$3,244). Including the cost of readmission in the variable cost made the contribution margin -$115,741 ± 16,023 (average -$16,534). CONCLUSIONS: Care of high-risk patients at tertiary and quaternary referral centers is a very expensive proposition and can lead to financial ruin under the current reimbursement system.
