Background Accurate electrocardiographic (ECG) differentiation of ventricular tachycardia (VT) from supraventricular tachycardia with aberrancy (SVT-A) on ECG is key to therapeutic decision-making in the emergency department (ED) setting. Objective The goal of this study was to test the accuracy and agreement of emergency medicine residents to differentiate VT from SVT-A using the Vereckei criteria. Methods Six emergency medicine residents volunteered to participate in the review of 114 ECGs from 86 patients with a diagnosis of either VT or SVT-A based on an electrophysiology study. The resident reviewers initially read 12-lead ECGs blinded to clinical information, and then one week later reviewed a subset of the same 12-lead ECGs unblinded to clinical information. Results One reviewer was excluded for failing to follow study protocol and one reviewer was excluded for reviewing less than 50 blinded ECGs. The remaining four reviewers each read 114 common ECGs blinded to clinical data and their diagnostic accuracy for VT was 74% (sensitivity 70%, specificity 80%), 75% (sensitivity 76%, specificity 73%), 61% (sensitivity 81%, specificity 25%), and 68% (sensitivity 84%, specificity 40%). The intraclass correlation coefficient (ICC) was 0.31 (95% CI 0.22 – 0.42). Eliminating two of the four reviewers who left a disproportionately high number of ECGs unclassified resulted in an increase in overall mean diagnostic accuracy (70% to 74%) and agreement (0.31 to 0.50) in the two remaining reviewers. Three reviewers read 45 common ECGs unblinded to clinical information and had accuracies for VT 93%, 93% and 78%. Conclusion The new single lead Vereckei criteria, when applied by emergency medicine residents achieved only fair-to-good individual accuracy and moderate agreement. The addition of clinical information resulted in substantial improvement in test characteristics. Further improvements (accuracy and simplification) of algorithms for differentiating VT from SVT-A would be helpful prior to clinical implementation.

LAM with uterine artery occlusion/ligation is a viable approach for removing large tumor loads while minimizing blood loss and precluding the need for power morcellation.

Background and Objective:Compare operative outcomes of laparoscopic hysterectomy in an outpatient hospital setting versus freestanding ambulatory surgery center.Methods:Retrospective cohort study of two groups in an outpatient hospital surgery department and freestanding ambulatory surgical center, both serving the Washington, DC area. Women, 18 years or older, who underwent laparoscopic hysterectomy for benign conditions in an outpatient hospital setting between 2011 and 2014 (n = 821), and at an ambulatory surgery center between 2013 and 2017 (n = 1210). Laparoscopic hysterectomy with retroperitoneal dissection and early ligation of the uterine arteries at the origin, performed by gynecologic surgical specialists from a single practice. Patient characteristics, medical history, uterine weight, pathology, operating times, estimated blood loss, and complications were analyzed.Results:The mean uterine size between settings was not significantly different (Ambulatory Surgery Center, 349.4 g; Hospital, 329.7 g). The largest uteri removed at the surgery center was 3500 g; at the hospital it was 2489 g. The surgery center had a shorter average operating time than the hospital (53.7 and 61.3 minutes, respectively; P < .001). Intraoperative and postoperative complication rates were not significantly different between settings (2.7% and 3.7%, surgery center; 2.1% and 4.8%, hospital). There were two hospital transfers from the surgery center: 1 for blood transfusion, and 1 for low oxygen saturation. Same-day discharge occurred in 99.8% of surgery center patients versus 88% hospital patients.Conclusions:Laparoscopic hysterectomy can be performed safely and effectively by skilled surgeons at a freestanding ambulatory surgery center, even in complex cases with large uteri.

Aim By evaluating operative outcomes relative to cost, we compared the value of minimally invasive hysterectomy approaches, including a technique discussed less often in the literature, laparoscopic retroperitoneal hysterectomy (LRH), which incorporates retroperitoneal dissection and ligation of the uterine arteries at their vascular origin. Methods Retrospective chart review of all women (N = 2689) aged greater than or equal to 18 years who underwent hysterectomy for benign conditions from 2011 to 2013 at a high‐volume hospital in Maryland, USA. Procedures included: laparoscopic supracervical hysterectomy, robotic‐assisted laparoscopic hysterectomy (RALH), total laparoscopic hysterectomy, laparoscopic‐assisted vaginal hysterectomy, total vaginal hysterectomy (TVH), and LRH. Results Total vaginal hysterectomy had the highest intraoperative complication rate (9.6%; P < 0.0001) but the lowest postoperative complication rate (1.8%; P < 0.0001). Robotics had the highest postoperative complication rate (11.4%; P < 0.0001). LRH had the shortest operative time (71.2 min; P < 0.0001) and the lowest intraoperative complication rates (2.1%; P < 0.0001). LRH and TVH were the least costly (averaging $4061 and $6416, respectively), while RALH was the most costly ($9354). Taking both operative outcomes and cost into account, LRH, TVH and laparoscopic‐assisted vaginal hysterectomy yielded the highest value scores; total laparoscopic hysterectomy, RALH, and laparoscopic supracervical hysterectomy yielded the lowest. Conclusion Understanding the value of surgical interventions requires an evaluation of both operative outcomes and direct hospital costs. Using a quality‐cost framework, the LRH approach as performed by high‐volume laparoscopic specialists emerged as having the highest calculated value.

Background: With surgical care contributing to the rising healthcare costs around the globe, quantifying the value of surgical modalities is critical to pushing healthcare systems in the direction of greater sustainability. The purpose of this study was to assess and compare the value of minimally invasive hysterectomy approaches, as defined by operative outcomes and patient satisfaction relative to direct hospital costs. Methods: Sequential mixed methods; retrospective chart review of all women (N = 2689) ≥ 18 years old who underwent hysterectomy for benign conditions from 2011 through 2013 at a suburban hospital in Maryland, USA; a mail survey of the same population was administered in June to October 2015. Procedures included laparoscopic supracervical hysterectomy (LSH), robotically assisted laparoscopic hysterectomy (RALH), total laparoscopic hysterectomy (TLH), laparoscopically assisted vaginal hysterectomy (LAVH), total vaginal hysterectomy (TVH), and laparoscopic retroperitoneal hysterectomy (LRH), a procedure that incorporates retroperitoneal dissection and ligation of the uterine arteries at their vascular origin. We estimated the value of each procedure by dividing quality over direct hospital costs, where quality was quantified by creating a summary composite score of the average operating time, estimated blood loss, complication and conversion rates, and patient satisfaction. Results: The majority of LRH and RALH procedures were performed by high-volume surgeons, while the majority of LSH and TVH procedures were performed by low-volume surgeons. RALH had the highest postoperative complication rate (11.4%; p < .0001). TVH had the highest intraoperative complication rate (9.6%; p < .0001) but lowest postoperative complication rate (1.8%; p < .0001). LRH had the shortest operating time (71.2 min; p < .0001) and lowest intraoperative complication rates (2.1%; p < .0001). LRH and TVH were the least costly ($4061 and $6416, respectively), while RALH was the most costly ($9354). LRH had the highest combined patient satisfaction score, followed by RALH, while TLH, LAVH, TVH, and LSH averaged similar scores. Conclusion: LRH, TVH, and LAVH yielded the highest value scores; LSH, TLH, and RALH yielded the lowest. Healthcare costs continue to escalate, in large part due to innovations in medical technology. For healthcare stakeholders seeking to control costs without sacrificing quality, it is critical to operationalize the value of varying surgical techniques, including measures of surgeon experience, operative outcomes, costs, and patient satisfaction.
