INTRODUCTION: The reliability and validity of the Cigarette Dependence Scale (CDS) has been tested in online studies and compared with other tobacco dependence measures. Findings regarding its ability to predict smoking cessation have been mixed. We examined whether the CDS predicted cessation among a sample that received nicotine replacement therapy (NRT) at a community workshop and assessed the incremental predictive validity of the CDS-5 and CDS-12 over the 2-item Heaviness of Smoking Index (HSI)...

Introduction: Within tobacco prevention programming, it is useful to identify youth that are at risk for experimenting with various tobacco products and e-cigarettes. The susceptibility to smoking construct is a simple method to identify never-smoking students that are less committed to remaining smoke-free. However, the predictive validity of this construct has not been tested within the Canadian context or for the use of other tobacco products and e-cigarettes. Methods: This study used a large, longitudinal sample of secondary school students that reported never using tobacco cigarettes and non-current use of alternative tobacco products or e-cigarettes at baseline in Ontario, Canada...

BACKGROUND: Clinical guidelines recommend knee muscle strengthening exercises to improve physical function. However, the amount of knee muscle strength increase needed for clinically relevant improvements in physical function is unclear. Understanding how much increase in knee muscle strength is associated with improved physical function could assist clinicians in providing appropriate strength gain targets for their patients in order to optimise outcomes from exercise. The aim of this study was to investigate whether an increase in knee muscle strength is associated with improved self-reported physical function following exercise; and whether the relationship differs according to physical function status at baseline...

Background Nurse Practitioner-Led Clinics are a new model of primary healthcare in Ontario. Nurse Practitioner-Led Clinics are distinctive in that nurse practitioners are the primary care providers working with an interprofessional team. There have been no evaluations of the quality of care within the Nurse Practitioner-Led Clinic model. Purpose Evaluation of the Nurse Practitioner-Led Clinic model, specifically for complex clinical presentations, will provide insights that may be used to inform improvements to the delivery of care in the Nurse Practitioner-Led Clinics...

This article describes how one Ontario Public Health Unit implemented a best practice guideline throughout the organization and across disciplines to achieve best practice outcomes in the delivery of client-centered care. Integration of evidence-informed practice presents challenges for both implementation and sustainability. Applying a best practice guideline in the public health setting can add to the challenge. To address this, a variety of interventions were applied: building an interdisciplinary team, adapting a Registered Nurses' Association of Ontario Best Practice Guideline to reflect public health practice for nursing and other disciplines, developing a working definition of "client," engaging staff in knowledge translation, developing policy to support practice change, and incorporating client-centered care principles into daily practice...

AIM: Frailty is understood as a dynamic non-linear process, and used to indicate age-related decline. Recent work has shown that adults with intellectual and developmental disabilities experience higher rates of frailty at much earlier ages than the general population. The present study describes transitions in frailty status (i.e. non-frail, pre-frail, frail) over 1 year, and explores the association between baseline frailty status and worsening/death over time. METHODS: Results are based on secondary analysis of 2893 individuals with intellectual and developmental disabilities receiving community-based home care services in Ontario (Canada)...

The extent of Canadian provincial variation in hip fracture surgical timing is unclear. Provinces performed a similar proportion of surgeries within three inpatient days after adjustment. Time to surgery varied by timing of admission across provinces. This may reflect different approaches to providing access to hip fracture surgery. INTRODUCTION: The aim of this study was to compare whether time to surgery after hip fracture varies across Canadian provinces for surgically fit patients and their subgroups defined by timing of admission...

Background: Major depressive disorder and generalized anxiety disorder are among the most commonly diagnosed mental illnesses in Canada; both are associated with a high societal and economic burden. Treatment for major depressive disorder and generalized anxiety disorder consists of pharmacological and psychological interventions. Three commonly used psychological interventions are cognitive behavioural therapy (CBT), interpersonal therapy, and supportive therapy. The objectives of this report were to assess the effectiveness and safety of these types of therapy for the treatment of adults with major depressive disorder and/or generalized anxiety disorder, to assess the cost-effectiveness of structured psychotherapy (CBT or interpersonal therapy), to calculate the budget impact of publicly funding structured psychotherapy, and to gain a greater understanding of the experiences of people with major depressive disorder and/or generalized anxiety disorder...

BACKGROUND: Diabetes is common among individuals with chronic psychotic illness, yet they receive lower quality of diabetes care than those without psychosis. Men usually receive higher quality diabetes care than women, but whether this holds true in chronic psychotic illness populations is unknown. We aimed to determine whether quality of diabetes care differs between men and women with chronic psychotic illness. METHODS: This population-based cohort study used Ontario health administrative data to compare women and men with comorbid chronic psychotic illness and diabetes mellitus (2011-2013)...

We sought to characterize non-communicable disease (NCD)-related and overall health service use among African and Caribbean immigrants living with HIV between April 1, 2010 and March 31, 2013. We conducted two population-based analyses using Ontario's linked administrative health databases. We studied 1525 persons with HIV originally from Africa and the Caribbean. Compared with non-immigrants with HIV (n = 11,931), African and Caribbean immigrants had lower rates of hospital admissions, emergency department visits and non-HIV specific ambulatory care visits, and higher rates of health service use for hypertension and diabetes...

Pharmaceuticals and personal care products (PPCPs) have been found in wastewater treatment plant (WWTP) effluents and their recipient watersheds. To assess the potential of WWTP effluents to alter fish behaviour, we caged male goldfish (Carassius auratus) for 21-days at three sites along a contamination gradient downstream from a WWTP which discharges into Cootes Paradise Marsh, on the western tip of Lake Ontario. We also included a fourth caging site as an external reference site within Lake Ontario at the Jordan Harbour Conservation Area...

Population growth has led to increased global discharges of wastewater. Contaminants that are not fully removed during wastewater treatment, such as pharmaceuticals and personal care products (PPCPs), may negatively affect aquatic ecosystems. PPCPs can bioaccumulate causing adverse health effects and behavioural changes in exposed fish. To assess the impact of PPCPs on wild fish, and to assess whether caged fish could be used as a surrogate for resident wild fish in future monitoring, we caged goldfish in a marsh affected by discharges of wastewater effluents (Cootes Paradise, Lake Ontario, Canada)...
