The Association between Birth by Caesarean Section and Otitis Media in Nova Scotian Children
(2017-11-21)Background. Birth by Caesarean section (CS) is a risk factor for allergic disorders, diabetes, and obesity. Otitis media (OM) is a common childhood illness. Risk factors for OM include allergic disorders and obesity; ... -
Comparison of Two Methods to Correct for Non-differential Misclassification in Meta-analysis
(2019-08-23)Like all data, administrative health data are susceptible to bias. In this project I focus on bias due to misclassification of disease outcome in the context of a meta-analysis. I propose a novel approach to random effects ... -
Depressive Symptoms and Sexual Health in University Students: The Role of Subscales in a Depression Screening Tool
(2016-05-04)Depressive symptoms have been shown to be associated with sexual risk-taking among young adults; however, whether this association is underpinned by specific types of depressive symptoms has not been examined. Using ... -
The effect of community of discharge on length of stay for unplanned hospitalizations: An indicator of community care integration?
(2020-08-07)Objective: Adjusted hospital length of stay (LOS), widely used to benchmark hospital efficiency, does not account for community-driven variation. We estimate the extent to which community affects LOS for unplanned ... -
Effect of Green Space Exposure on the Relationship Between Socioeconomic Status and Mental Health Among Older Canadians
(2022-08-22)Green space is considered to be a health-promoting feature of both natural and built environments and has the potential to influence mental health outcomes at both an individual and population level. Green space interventions, ... -
EXAMINING THE PROGNOSTIC VALUE OF FRAILTY DETERMINED BY A MULTIDIMENSIONAL QUESTIONNAIRE, THE FRAILTY ASSESSMENT IN CARE-PLANNING TOOL (FACT), IN CARDIAC SURGERY
(2018-05-01)We assessed whether the Frailty in Care-Planning Tool (FACT) added discriminatory power to a standard cardiac surgery risk prediction model for mortality and major adverse cardiac events (MACE). To date, risk prediction ... -
Examining the Relationship Between Traumatic Brain Injury and Substance Use and Mental Health Outcomes in the Canadian Population
(2013-09-06)This thesis examines the associations between substance use/ misuse and mental health outcomes among Canadians with a Traumatic Brain injury (TBI). Its primary aim is to explore whether or not individuals with a TBI have ... -
Investigating the role of frailty in the expression of dementia
(2020-08-28)Background: Frailty is related to neuropathological features of Alzheimer’s disease (AD) as well as cognitive decline and dementia. Objectives: 1) determine whether frailty moderates the relationship between neuropathology ... -
LIMITING LYME DISEASE: USING SYSTEM DYNAMICS SIMULATION TO TARGET HEALTH INTERVENTIONS
(2016-04-08)Lyme disease is the most common vector-borne infection in North America. However, little is known about the impact of public and physician awareness and behaviour on health outcomes. In order to address this limitation, ... -
Macrosomic Infants Born to Non-diabetic Mothers in Nova Scotia: Determinants and Development of a Risk Prediction Model
(2016-07-22)This retrospective cohort study investigated the rates and risk factors of macrosomia in non-diabetic women and developed a clinically relevant model to predict macrosomia in mid-pregnancy. Logistic regression was used to ... -
Modelling of spatial infection spread through heterogeneous population: from lattice to PDE models
(2021-12-20)We derive a PDE model of the infection spread, which takes population density into account. This model is a continuum limit of agent-based model of human movement. Numerical simulations of the model show that dense population ... -

Opioid Prescribing Patterns and Prolonged Opioid Use in Opioid-Naive Adults after Surgical and Emergency Care in Nova Scotia
(2022-05-03)I conducted three studies about opioid prescribing and prolonged opioid use - an important outcome of opioid prescribing for acute pain. In the first study I employed systematic review methodology to summarize risk of ... -
Patterns of Opioid Exposure in the Emergency Care System and Prolonged Opioid Use Among Opioid-Naïve Adults With Low Back Pain
(2022-08-02)The objectives of this thesis were to: 1) describe the characteristics of opioids delivered to opioid-naïve adults with low back pain as they transition through a Canadian emergency care system; 2) identify different ... -
Risk Estimation using Random Forests
(2017-04-06)The random forest probability machine (RFPM) introduced by Dasgupta et al. (2014) is a consistent, non-parametric regression technique that, when applied to binary outcomes, enables calculation of predictor effect size ... -
Risk Factors for Central Venous Line Associated Bloodstream Infection in Pediatric Patients 0-18 Years of Age: A Cohort Study
(2014-12-10)This cohort study examined Central Venous Line (CVL) use and risk of Central Line Associated Bloodstream Infection (CLABSI) in patients 0 to 18 years of age at a pediatric tertiary care referral center serving 2.3 million ... -
Risk factors for surgical site infection following Caesarean section in Nova Scotian women
(2015)Surgical site infections (SSIs) can be serious complications after Caesarean section. Therefore, we determined among women undergoing a Caesarean section in Nova Scotia: 1) the incidence of SSI to hospital discharge, 2) ... -
Severe Respiratory Syncytial Virus (RSV) Infection in Preterm Infants and Later Onset of Asthma
(2018-04-06)Respiratory Syncytial Virus (RSV)-hospitalizations have a substantial disease burden during an infant’s first year of life, and long-term consequences such as asthma remain unclear. This study aimed to quantify the incidence ... -
SMALL AREA VARIATIONS IN UNPLANNED REPEAT HOSPITALIZATION IN NOVA SCOTIA
(2018-04-25)Objective: Unplanned readmission to hospital is widely used as an indicator of hospital performance. Community-based primary health care systems likely also play a role in unexpected returns to hospital. Our objective was ...
