In this thesis, I present the projects and activities I have undertaken as a Master of Philosophy in Applied Epidemiology (MAE) Scholar in Victoria between February 2015 and September 2016. I was placed with the Communicable Disease Epidemiology and Surveillance (CDES) Unit at the Victorian Department of Health and Human Services, and the Victorian Infectious Diseases Reference Laboratory (VIDRL) Epidemiology Unit. Through these placements I experienced the day-to-day activities of a state public health unit as well as an applied public health research environment.I conducted a cohort study to identify the source of a large, highly publicised outbreak of Salmonella Typhimurium at a five-star hotel in Melbourne, which was identified as raw-egg mayonnaise used in sandwich fillings served at a High Tea. For my data analysis project, I investigated the epidemiology of legionellosis in Victoria between 2000 and 2015 to determine whether the ubiquity of the Legionella pneumophila specific urinary antigen test is creating an 'epidemiological blind spot' for non - Legionella pneumophila infections. I found that whilst this method was ubiquitous prior to and during the study period, the rate of infection with non-Legionella pneumophila species did not decline in parallel as expected if urinary antigen testing routinely precluded their detection. I evaluated the complex Victorian influenza surveillance system, which involved analysis of data captured by the system from 2005 - 2014. As a whole, the system was found to perform well and the data collected were used to inform public health activities. Geographic representativeness of syndromic ILI data was high, demonstrating its utility as a surveillance tool, and the widespread uptake of molecular diagnostic testing enhanced overall system sensitivity, timeliness and flexibility. In addition, the data collected enabled robust estimates of seasonal vaccine effectiveness to be determined which informs local public health action and global vaccine development. However, important deficiencies that prevent the system from achieving a number of its objectives were identified. Most importantly, the ability of the current system to guide planning and implementation of policy and to detect and control outbreaks is limited, and laboratory testing denominator data are not available to facilitate interpretation of seasonal trends and true influenza incidence.My epidemiological project was an analysis of whether registering with Spleen Australia [formerly the Victorian Spleen Registry (VSR)], which provides education, clinical guidance and health promotion reminders, reduces the incidence of overwhelming post splenectomy infection amongst Victorian registrants without a spleen. By conducting a survival analysis, I found that VSR registration was indeed associated with a highly significant (p

In this thesis, I present the projects and activities I have undertaken as a Master of Philosophy in Applied Epidemiology (MAE) Scholar in Victoria. Between February 2013 and December 2014, I was placed with Communicable Disease Epidemiology and Surveillance at the Victorian Department of Health and the Epidemiology Unit at the Victorian Infectious Diseases Reference Laboratory (VIDRL). Through these placements I experienced the day-to-day activities of a public health unit, as well as the applied public health research environment provided in a reference laboratory setting. During my MAE I analysed data to examine the relationships between antimicrobial resistance patterns in Shigella isolates and risk factors for shigellosis. I have found that location of travel is a possible marker of antimicrobial resistance patterns in shigellosis cases and found significantly elevated levels of ciprofloxacin resistance amongst travellers returning from India and their contacts. This project also highlights the prominence of periodic outbreaks amongst men who have sex with men (MSM) in driving shigellosis case numbers in Victoria and indicates a reconsideration of Australian treatment guidelines for shigellosis may be needed. As a result of this project, I also communicated with selected general practitioners and the community to increase awareness of an outbreak of shigellosis amongst MSM in 2014. My epidemiological project examined the effects of restriction criteria and covariate inclusion in the case-test negative design to estimate seasonal influenza vaccine effectiveness (VE). Using six years of data from the Victorian General Practice Sentinel Surveillance System I defined an optimum logistical regression model for this new, but growing, method of analysing sentinel influenza surveillance data to provide rapid annual estimates of influenza VE. I also report supporting evidence that repeated seasonal influenza vaccination in both the current and previous year may be less effective at preventing influenza than vaccination in only the current season. I report on two outbreak investigations. The first was a cohort investigation into an outbreak of gastroenteritis of unknown aetiology following a catered lunch. Attendees at the lunch were divided into three groups representing a standard meal in low, middle and high-income countries. I believe the source of illness to be a dahl curry served as part of the low-income country meal and stored in a hot box prior to serving. We have communicated potential improvements in food safety practices the to prevent further outbreaks. The second outbreak is a descriptive investigation of a Salmonella Typhimurium phage type 64 cluster identified in Victoria in 2013. I evaluated national hepatitis A surveillance in Australia, focused on detection of common-source multi-jurisdictional outbreaks. I consider the potential to enhance surveillance using nationally collated genotyping, sequencing and standardised exposure data. Finally, I present two teaching activities conducted during my MAE; a teaching session on selection bias and a lesson from the field introducing directed acyclic graphs I prepared for my fellow MAE2013 cohort. This thesis provides an account of my MAE experience, fulfils the requirements of the program and outlines the contribution my work has made to public health in Victoria.

Endorsed by the Australasian College for Infection Prevention and Control (ACIPC) ACIPC is the peak body for infection prevention and control professionals in the Australasian region. Healthcare-associated Infections (HAIs) are a major threat to patient safety and the quality of healthcare globally. Despite this, Australia does not have a nationally coordinated program for the surveillance and reporting of HAIs. Epidemiology of Healthcare-associated Infections in Australia is Australia’s first peer-reviewed, evidence-based assessment of the epidemiology of HAIs using publicly available data from hospital-acquired complications (HACs), state-based surveillance systems and peer-reviewed and grey literature sources. This important work has been compiled by some of Australia’s leading infection control professionals and researchers. It will build national consensus on definitions, surveillance methodology and reporting of the incidence of HAIs. In doing so, it provides hospitals and those working in infection prevention and control an opportunity to benchmark and evaluate interventions to reduce infections and ensure transparency on reporting methods that will strengthen Australia’s efforts to prevent and control HAIs. Here is a great article published in Sydney Morning Herald on the publication of Epidemiology of Healthcare-associated infections in Australia. Collated publicly available HAI surveillance definitions from jurisdictions across Australia Collated publicly available national HACs HAI data derived from the associated surveillance programs Identification of the gaps in both publicly available HAI data from different sources and the lack of publicly available HAI surveillance data in one serialised title Supporting video summarising key content

Over the past two decades increasing interest has emerged in the contribu tions that the social sciences might make to the epidemiological study of patterns of health and disease. Several reasons can be cited for this increasing interest. Primary among these has been the rise of the chronic, non-infectious diseases as important causes of morbidity and mortality within Western populations during the 20th century. Generally speaking, the chronic, non infectious diseases are strongly influenced by lifestyle variables, which are themselves strongly influenced by social and cultural forces. The under standing of the effects of the behavioral factors in, say, hypertension, thus requires an understanding of the social and cultural factors which encourage obesity, a sedentary lifestyle, non-compliance with anti-hypertensive medica tions (or other prescribed regimens), and stress. Equally, there is a growing awareness that considerations of human behavior and its social and cultural determinants are important for understanding the distribution and control of infectious diseases. Related to this expansion of epidemiologic interest into the behavioral realm 'has been the development of etiological models which focus on the psychological, biological and socio-cultural characteristics of hosts, rather than exclusive concern with exposure to a particular agent or even behavioral risk. Also during this period advances in statistical and computing techniques have made accessible the ready testing of multivariate causal models, and so have encouraged the measurement of the effects of social and cultural factors on disease occurrence.
