First-Case Operating Room Delays: Patterns Across Urban Hospitals Of A Single Health Care System, Callie M. Cox Bauer, Danielle M. Greer, Kiley B. Vander Wyst, Scott A. Kamelle Aug 2019

First-Case Operating Room Delays: Patterns Across Urban Hospitals Of A Single Health Care System, Callie M. Cox Bauer, Danielle M. Greer, Kiley B. Vander Wyst, Scott A. Kamelle

Callie Cox Bauer, DO, FACOG

Purpose

Operating room delays decrease health care system efficiency and increase costs. To improve operating room efficiency in our system, we retrospectively investigated delay frequencies, causes and costs.

Methods

We studied all first-of-the-day nonemergent surgical cases performed at three high-volume urban hospitals of a large health system from July 2012 to November 2013. Times for patient flow from arrival to procedure start and documented reasons for delay were obtained from electronic medical records. Delay was defined as patient placement in the operating room later than scheduled surgery time. Effects of patient characteristics, late patient arrival to the hospital, number of …

Diversity Of Behaviour During Novel Object Tests Is Reduced In Pigs Housed In Substrate-Impoverished Conditions, Françoise Wemelsfelder, Marie Haskell, Michael T. Mendl, Sheena Calvert, Alistair B. Lawrence Jun 2016

Diversity Of Behaviour During Novel Object Tests Is Reduced In Pigs Housed In Substrate-Impoverished Conditions, Françoise Wemelsfelder, Marie Haskell, Michael T. Mendl, Sheena Calvert, Alistair B. Lawrence

Françoise Wemelsfelder, PhD

Modern intensive farming conditions lack the diversity of substrates present in more natural environments and offer young animals fewer opportunities for interaction. Evidence exists that this may affect the organization of interactive patterns of behaviour, but shifts in behavioural diversity have not been measured directly. We investigated the effect of the substrate in the home pen on the diversity of behaviour in young growing pigs, Sus scrofa. Over 5 months, 26 pigs were housed singly in either substrate-impoverished (SI) or substrate-enriched (SE) conditions. Once every month we recorded the behaviour of these pigs in detail both in the home pens …


Flooring And Driving Conditions During Road Transport Influence The Behavioural Expression Of Cattle, Catherine A. Stockman, Teresa Collins, Anne L. Barnes, David Miller, Sarah L. Wickham, David T. Beatty, Dominique Blache, Françoise Wemelsfelder, Patricia A. Fleming Jun 2016

Flooring And Driving Conditions During Road Transport Influence The Behavioural Expression Of Cattle, Catherine A. Stockman, Teresa Collins, Anne L. Barnes, David Miller, Sarah L. Wickham, David T. Beatty, Dominique Blache, Françoise Wemelsfelder, Patricia A. Fleming

Françoise Wemelsfelder, PhD

This study examined whether observers could distinguish between cattle that were exposed to various road transport conditions: Experiment 1 compared a manipulated flooring treatment (non-grip flooring, NG) with a control transport event (grip flooring, G) and Experiment 2 compared a manipulated driving style (stop-start driving, SS) with a control transport event of smooth, continuous (C) driving. The behavioural expression of cattle was assessed through the process of Qualitative Behavioural Assessment (QBA), and these assessments were tested for correlation with various physiological parameters. Fourteen Angus steers were assessed. Blood samples were collected immediately before and after transport, and heart rate and …


Experience In Substrate-Enriched And Substrate-Impoverished Environments Affects Behaviour Of Pigs In A T-Maze Task, Michael Mendl, Hans W. Erhard, Marie Haskell, Françoise Wemelsfelder, Alistair B. Lawrence Jun 2016

Experience In Substrate-Enriched And Substrate-Impoverished Environments Affects Behaviour Of Pigs In A T-Maze Task, Michael Mendl, Hans W. Erhard, Marie Haskell, Françoise Wemelsfelder, Alistair B. Lawrence

Françoise Wemelsfelder, PhD

Previous research showed that pigs reared in substrate-impoverished conditions performed a smaller proportion of their total behavioural repertoire in their home pens (showed lower behavioural diversity), than pigs reared in substrate-enriched conditions. This study examined whether these differences were the result of fundamental changes in behavioural organisation. A T-maze task was used to test the hypothesis that substrate-impoverished pigs are prone to develop fixed, unvarying behaviour which may underlie their reduced behavioural diversity. They were predicted to be poorer at reversing previous response patterns in the maze, and less able to alter their behaviour in response to a novel (distracting) …


The Effect Of Substrate-Enriched And Substrate-Impoverished Housing Environments On The Diversity Of Behaviour In Pigs, Marie Haskell, Françoise Wemelsfelder, Michael T. Mendl, Sheena Calvert, Alistair B. Lawrence Jun 2016

The Effect Of Substrate-Enriched And Substrate-Impoverished Housing Environments On The Diversity Of Behaviour In Pigs, Marie Haskell, Françoise Wemelsfelder, Michael T. Mendl, Sheena Calvert, Alistair B. Lawrence

Françoise Wemelsfelder, PhD

In intensive farming situations, growing animals are housed in relatively barren environments. The lack of opportunity to perform substrate-interactive and manipulative behaviour patterns may affect the expression and organization of these behaviours. However, making direct comparisons of the behaviour expressed in environments of differing physical complexity is difficult. In this experiment a relative diversity index was used to compare the behavioural repertoires of pigs housed in two different environments for a period of five months. One group of pigs (substrate-enriched) had straw, forest bark and branches added to the standard pens and the other group (substrate-impoverished) did not. The pigs …


A Critical Review Of Electrical Water-Bath Stun Systems For Poultry Slaughter And Recent Developments In Alternative Technologies, Sara J. Shields, A. B. M. Raj Jun 2015

A Critical Review Of Electrical Water-Bath Stun Systems For Poultry Slaughter And Recent Developments In Alternative Technologies, Sara J. Shields, A. B. M. Raj

Sara Shields, PhD

Prior to slaughter, most farmed birds move through a constant-voltage, multiple- bird, electrical water-bath stun system. Using this system subjects live birds to stressful and painful shackling, and the potential exists for them to receive prestun electric shocks and induction of seizures while still conscious. The existing elec- trical water-bath stunner settings, particularly those used in U.S. slaughter plants, are not necessarily based on sound scientific data that they produce a consistent, immediate stun, and research indicates that they are not effective in all birds. Further, in multiple-bird, electrical water-bath systems, birds may miss the stunner completely. Evidence suggests that …


Impact Of Radio-Frequency Identification (Rfid) Technologies On The Hospital Supply Chain: A Literature Review, Alberto Coustasse, Shane Tomblin, Chelsea Slack Jun 2014

Impact Of Radio-Frequency Identification (Rfid) Technologies On The Hospital Supply Chain: A Literature Review, Alberto Coustasse, Shane Tomblin, Chelsea Slack

Shane Tomblin

Supply costs account for more than one-third of the average operating budget and constitute the second largest expenditure in hospitals. As hospitals have sought to reduce these costs, radio-frequency identification (RFID) technology has emerged as a solution. This study reviews existing literature to gauge the recent and potential impact and direction of the implementation of RFID in the hospital supply chain to determine current benefits and barriers of adoption. Findings show that the application of RFID to medical equipment and supplies tracking has resulted in efficiency increases in hospitals with lower costs and increased service quality. RFID technology can reduce …


The Long Haul: Risks Associated With Livestock Transport, Michael Greger May 2014

The Long Haul: Risks Associated With Livestock Transport, Michael Greger

Michael Greger, MD, FACLM

The Food and Agriculture Organization (FAO) of the United Nations describes live animal transport as “ideally suited for spreading disease,” given that animals may originate from different herds or flocks and are “confined together for long periods in a poorly ventilated stressful environment.” Given the associated “serious animal and public health problems,” the Federation of Veterinarians of Europe has called for the replacement of the long-distance transportation of live animals for slaughter as much as possible to a “carcass-only trade.” In the United States, more than 50 million live cattle, sheep, and pigs and an unknown number of the more …

A Neural Network Decision-Making Model For Job-Shop Scheduling”, Davood Golmohammadi Phd Dec 2012

A Neural Network Decision-Making Model For Job-Shop Scheduling”, Davood Golmohammadi Phd

Davood Golmohammadi

Scheduling in a job-shop system is a challenging task. Simulation modelling is a well-known approach for evaluating the scheduling plans of a job-shop system; however, it is costly and time-consuming, and developing a model and interpreting the results requires expertise. As an alternative, we have developed a neural network (NN) model focused on detailed scheduling that provides a versatile job-shop scheduling analysis framework for management to easily evaluate different possible scheduling scenarios based on internal or external constraints. A new approach is also proposed to enhance the quality of training data for better performance. Previous NN models in scheduling focus …
