Can the marshmallow esophagram replace high-resolution manometry as an appropriate screening for esophageal motility prior to anti-reflux surgery?

BACKGOUND: The purpose of our study was to evaluate the use of minimally invasive Marshmallow Swallow Study (MSS) as a preoperative screening technique for patients and correlate marshmallow results with High Resolution Manometry (HRM) results and post-operative dysphagia following antireflux surgery. METHODS: A retrospective electronic chart review of data on 61 adult patients undergoing MSS was completed. Patients were included if they completed the MSS as well as: HRM and/or antireflux surgery. RESULTS: Sixty-one patients completed MSS. Of the 37 patients that completed HRM, 27 had abnormal results. 23 of these 27 patients who had abnormal results also failed MSS. The NPV for a failure on the MSS and abnormal HRM results is 0.767(p-value = 0.360). The PPV for a pass on the MSS and no post-operative dysphagia is 0.833 (p-value = 0.656). CONCLUSIONS: MSS is an effective screening tool for ruling out major esophageal motility disorders and can prevent need for invasive HRM.

Multisite Implementation of Radiology-TEACHES (Technology-Enhanced Appropriateness Criteria Home for Education Simulation).

PURPOSE: After encouraging results from a single-institution pilot, a novel case-based education portal using integrated clinical decision support at the simulated point of order entry was implemented at multiple institutions to evaluate whether the program is scalable and results transferable. The program was designed to fill key health systems' science gaps in traditional medical education curricula, ultimately aiding the transition from volume to value in health care. The module described uses commonly encountered medical vignettes to provide learners with a low-stakes educational environment to improve their awareness and apply curricular content regarding appropriate resource utilization, patient safety, and cost. METHODS: In 2016 and 2017, the team implemented the modules at eight US medical schools. A total of 199 learners participated in this institutional review board-approved study; 108 completed the module, and 91 were in the control group. RESULTS: The module group had higher posttest scores than their control group peers, after controlling for pretest scores (ß = 4.05, P < .001). The greatest knowledge gains were on questions related to chest radiography (22% improvement) and adnexal cysts (20.33% improvement) and the least on items related to pulmonary embolism (0.33% improvement). The majority of learners expressed satisfaction with the educational content provided (70.4%) and an increased perception to appropriately select imaging studies (65.2%). CONCLUSIONS: This program is promising as a standardized educational resource for widespread implementation in developing health systems science curricula. Learners at multiple institutions judged this educational resource as valuable and, through this initiative, synthesized practice behaviors by applying evidence-based guidelines in a cost-effective, safe, and prudent manner.
