Background: Colorectal cancer (CRC) screening with guaiac fecal occult blood test (gFOBT) reduces CRC-related death. Average risk individuals should be recalled for screening with gFOBT every 2 years in order to maximize effectiveness. However, adherence with repeated testing is often suboptimal.

Background: This paper identifies patterns of health inequalities (consistency and magnitude) of socioeconomic disparities for multiple maternal and child health (MCH) outcomes that represent different health care needs of mothers and infants.

Methods: Using cross-sectional national data (unweighted sample = 6,421, weighted =76,508) from the Canadian Maternity Experiences Survey linked with 2006 Canadian census data, we categorized 25 health indicators of mothers of singletons into five groups of MCH outcomes (A. maternal and infant health status indicators; B.

Regular screening using guaiac fecal occult blood test (gFOBT) reduces mortality from colorectal cancer (CRC). The objective of this study was to determine whether the addition of a gFOBT kit to a second mailed invitation compared to a second mailed invitation alone increases CRC screening among eligible persons who did not respond to an initial mailed invitation. We conducted a cluster randomized controlled trial, with the physician as the unit of randomization.

Objective: To systematically review the diagnostic accuracy of clinical features associated with colorectal cancer (CRC) presenting in primary care.

Data Sources: MEDLINE and EMBASE were searched for studies in primary care that provided information on clinical features predictive of CRC. Positive predictive values were used to guide the determination of clinical features associated with increased risk of CRC.

Purpose: Primary care is the cornerstone of the health care system and increasingly countries are developing indicators for assessing quality in primary care practices. The 'Quality Tool', developed in Ontario, Canada, provides a framework for assessing practices and consists of indicators and criteria. The purpose of this study was to validate the indicators and simplify the Quality Tool.

The Institute of Medicine (IOM) framework has been used frequently to assess and monitor quality in secondary and tertiary care, but not in primary care. This article describes and proposes a conceptual framework for categorizing primary care indicators that align with the IOM's six aims for quality in healthcare performance (Safe, Effective, Patient-Centred, Timely, Efficient and Equitable.) Using an iterative process, the authors developed and compared a primary care framework for categorizing indicators in the Quality in Family Practice Book of Tools (QBT) with the IOM aims and other local healthcare systems frameworks (Integrated and Continuous, Appropriate Practice Resources).

Objective: To determine family physician perspectives regarding the acceptability and effectiveness of 2 interventions-a targeted, mailed invitation for screening to patients, and family physician audit-feedback reports-and on the colorectal cancer (CRC) screening program generally. This information will be used to guide program strategies for increasing screening uptake.

Design: Qualitative study.

Objectives: To compare policies and practices of routine interventions in labour and birth in Canadian hospitals in 1993 and 2007 and to describe trends regarding adherence to evidence-based guidelines.

Methods: We used data from surveys of Canadian hospitals in 1993 and 2007 on routine maternity care practices and policies, including interventions in labour and birth.

Results: The response rate of hospitals in 1993 was 91% (523/572), and in 2007 it was 92% (323/353).

Background: Appropriate screening may reduce the mortality and morbidity of colorectal, breast, and cervical cancers. Several high-quality systematic reviews and practice guidelines exist to inform the most effective screening options. However, effective implementation strategies are warranted if the full benefits of screening are to be realized.

Background: Appropriate screening may reduce the mortality and morbidity of colorectal, breast, and cervical cancers. However, effective implementation strategies are warranted if the full benefits of screening are to be realized. As part of a larger agenda to create an implementation guideline, we conducted a systematic review to evaluate interventions designed to increase the rate of breast, cervical, and colorectal cancer (CRC) screening.

Problem Addressed: To improve integration of cancer care, Cancer Care Ontario-a provincial agency responsible for planning, advising on, implementing, and monitoring initiatives to improve cancer outcomes-proposed a primary care and cancer engagement strategy in its Ontario Cancer Plan 2008-2011.

Objective Of Program: The strategy was designed to focus initially on improving screening for colorectal cancer in primary care settings and would expand to improving primary care integration, early detection, decreased mortality, and better patient experiences throughout the whole cancer journey.

Program Description: Following a symposium on integrating family practice and cancer care, leaders from Cancer Care Ontario and the Ontario College of Family Physicians developed an action plan.

Background: Cluster randomized trials (CRTs) are increasingly used to assess the effectiveness of interventions to improve health outcomes or prevent diseases. However, the efficiency and consistency of using different analytical methods in the analysis of binary outcome have received little attention. We described and compared various statistical approaches in the analysis of CRTs using the Community Hypertension Assessment Trial (CHAT) as an example.

Objective: High blood pressure is an important and modifiable cardiovascular disease risk factor that remains under-detected and under-treated. Community-level interventions that address high blood pressure and other modifiable risk factors are a promising strategy to improve cardiovascular health in populations. The present study is a community cluster-randomised trial testing the effectiveness of CHAP (Cardiovascular Health Awareness Program) on the cardiovascular health of older adults.
