MaineHealth Maine Medical Center

Problem/Impact Statement:

85% of first cases at Maine Medical Center for Vascular Surgery start late. According to one study done by Aurora Health Care; of 5,500 first case surgeries, 88% of them started late. The impact of this is far reaching. It is not in alignment with MMC value of Patient Centered Care because the patient becomes dissatisfied waiting to be brought in to surgery , they are fasting for longer than anticipated, and being away from their family while they wait causing anxiety. The financial impact is $1995 for each 1⁄2 hr. of O.R. time. Furthermore, this may result …

Sub-Retinal Abscess As Presenting Feature Of Endogenous Candida Endophthalmitis, Sidra Zafar, Rehman Siddiqui

Section of Neurosurgery

The first line of treatment for lumbar spinal stenosis (with or without lumbar degenerative spondylolisthesis) involves conservative options such as anti-inflammatory drugs and analgesics. Approximately, 10%-15% of patients require surgery. Surgical treatment aims to decompress the spinal canal and dural sac from degenerative bony and ligamentous overgrowth. Different studies have given conflicting results. The aim of our study is to clear the confusion by comparing two surgical techniques. This meta-analysis was conducted in accordance with the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines. A literature search was conducted of the Ovid Embase, Scopus, Pubmed, Ovid Medline, Google …

Educational Prevention Program Of Surgical Site Infections (Ssi), Carena Leung

Master's Projects and Capstones

Surgical site infections (SSI) cause negative health care effects to patients and hospitals. SSI is one of the most common types of healthcare-associated infections (HAI) accounting for 31% among hospitalized patients (Centers for Disease Control and Prevention [CDC], 2012). It is associated with prolonged length of stays (LOS), higher morbidity and mortality, and increased healthcare costs. The purpose of this quality improvement project is to decrease SSI rates by enhancing patient education and engagement in preoperative care and hygiene before surgery. In a metropolitan pediatric hospital, a microsystem analysis of the preoperative unit was conducted before generating the SSI Prevention …

Improving Follow-Up Skeletal Survey Compliance In Suspected Nonaccidental Trauma Patients: What's The Fuss About?, Tong Gan, John M. Draus Jr.

Surgery Faculty Publications

Introduction: Nonaccidental trauma (NAT) victims account for a significant percentage of our pediatric trauma population. The skeletal survey (SS) and follow-up skeletal survey (FUSS) are essential in the evaluation of selected NAT patients. We identified that our clinically indicated FUSS completion rate was suboptimal. We hypothesized that implementing an intervention of postdischarge follow-up in our pediatric surgery clinic would improve FUSS completion rates. Methods: A follow-up clinic for NAT patients was established in July 2013. A retrospective review was performed of all suspected NAT cases younger than 2 years old seen at Kentucky Children’s Hospital between November 2012 and February …

Impact Of Race And Insurance On Door-To-Appendectomy Time Among Pediatric Patients, Carla M. Lopez, Emily R. Christison-Lagay, Daniel Solomon

Journal of Health Disparities Research and Practice

Racial and ethnic disparities in the rate of appendiceal rupture have been widely reported among the pediatric population. The main reasons for this remain largely unknown given that previous explanations pointing to signs of poor health care access have recently been shown to account for only a small percentage of the difference in perforation rates between white and minority children. Because the risk of perforation increases with time, racial disparities in time delay from emergency department presentation to OR appendectomy may help account for the higher appendiceal perforation rates observed among minority children. This is the first study dedicated to …

Value Of Routine Preoperative Tests For Coagulation Before Elective Cranial Surgery. Results Of An Institutional Audit And A Nationwide Survey Of Neurosurgical Centers In Pakistan, Naveed Zaman, Muhammad Bilal Tariq, Saad Akhtar, Sidra Sattar, Wajeeha Tariq, Muhammad Shahzad Shamim, Samie Asghar

Section of Neurosurgery

Background: Routine preoperative blood testing has become a dogma. The general practice is to order preoperative workup as a knee-jerk response rather than individualize it for each patient. The fact that the bleeding brain tends to swell, which coupled with limited options for proximal control, packing, and overall hemostasis, leads to an overemphasis on the preoperative coagulation profile.
Material and methods: This is a retrospective review of the medical records of patients admitted at Aga Khan University Hospital from January 2010 to December 2015 for an elective craniotomy. The hospital registry was used to identify files for review. Data were …

Enhanced Co-Registration Methods To Improve Intracranial Electrode Contact Localization., Walter A. Hinds, Amrit Misra, Michael R. Sperling, Ashwini Sharan, Joseph I. Tracy, Karen A. Moxon

Department of Neurology Faculty Papers

Background: Electrode contact locations are important when planning tailored brain surgeries to identify pathological tissue targeted for resection and conversely avoid eloquent tissue. Current methods employ trained experts to use neuroimaging scans that are manually co-registered and localize contacts within ~2 mm. Yet, the state of the art is limited by either the expertise needed for each type of intracranial electrode or the inter-modality co-registration which increases error, reducing accuracy. Patients often have a variety of strips, grids and depths implanted; therefore, it is cumbersome and time-consuming to apply separate localization methods for each type of electrode, requiring expertise across …
