Background: Delays in first cases contribute to multiple operating room (OR) inefficiencies and decreases in OR productivity.
Methods: Lean process improvement methods were used to redesign the existing workflow for elective first cases of the day in a large, urban, public hospital. First case start times were prospectively recorded from May 2, 2016 through December 29, 2017.
Results: Data from 415 operating days were examined, 86 days prior to, 35 days during, and 294 days after implementation of interventions in the pre-operative holding area. During this time, of 23,891 operations performed, 14,981 were elective procedures, 5963 (39.8%) of which were first cases of the day. The mean rate of elective first case on-time starts per week went from 23.5% before and during to 73.0% after implementation of lean interventions (p < 0.0000001).
Conclusions: Implementation of lean interventions in the pre-operative holding area was associated with significantly improved rates of elective first case on-time starts.

The Role of Fluoroscopic Guidance in Spinal Drain Placement for Thoracoabdominal Aneurysm Repair Patients: A Retrospective Study.
J Cardiothorac Vasc Anesth
December 2024
Henry Ford Hospital, Detroit, MI.
Objectives: To evaluate outcomes after implementation of a preoperative protocol requiring fluoroscopic guidance in patients undergoing thoracoabdominal aortic aneurysm (TAAA) repair identified as being at risk for spinal drain placement complications.
Design: This retrospective analysis included patients who underwent spinal drain placement for TAAA repair between November 2013 and November 2018. Patient outcomes were assessed before (control) and after (study) protocol implementation.

This study aimed to determine hospital fear points, specific aspects of the hospital experience that are particularly frightening for children, and fear levels of children 5-10 years old who are admitted to the hospital. This descriptive cross-sectional study of 210 children in eastern Turkey aged 5-10 years used a Demographic Findings and Hospital Fears Form and the Child Fear Scale to collect data about the children's demographics, the opinions of the mothers about their children's fears, and the children's fears about the hospital. Children in the outpatient treatment services and emergency department were afraid of blood drawing, intravenous insertion, injections (shots), and separation from their mothers.

Infrainguinal bypass for limb salvage has comparable mortality and affords a better chance of home discharge than amputation among octogenarians.
J Vasc Surg
January 2025
The George Washington University Hospital, Department of Surgery, Washington, D.C., USA.
Background: Infrainguinal bypass for chronic limb-threatening ischemia (CTLI) in octogenarians is considered a high-risk procedure due to the presumed associated frailty of the patient population. However, the alternative which is major amputation may not be a better option. This study retrospectively compares the outcomes of bypass versus major amputation for functionally independent and partially dependent patients.

Background: Wall shear stress (WSS) plays a crucial role in the natural history of intracranial aneurysms (IA). However, spatial variations among WSS have rarely been utilized to correlate with IAs' natural history. This study aims to establish the feasibility of using spatial patterns of WSS data to predict IAs' rupture status (i.
