Abstract

Insights

This review identifies three effective knowledge translation (KT) interventions to boost participation in organized cancer screening programs. These include community-based, lay/peer, and targeted health education strategies.

Area of Science:

  • Public Health
  • Health Services Research
  • Cancer Prevention

Background:

  • Low participation rates in organized cancer screening programs remain a challenge.
  • Effective knowledge translation (KT) and implementation strategies are crucial for improving public health outcomes.
  • Ontario, Canada faces specific needs in cancer screening program engagement.

Purpose of the Study:

  • To support knowledge translation and implementation of interventions aimed at increasing participation in organized cancer screening programs in Ontario, Canada.
  • To identify and summarize evidence-based KT interventions for cancer screening.
  • To provide guidance for selecting and adapting interventions for diverse contexts.

Main Methods:

  • A comprehensive literature search identified over 900 references.
  • References were screened using exclusion criteria and categorized by intervention type.
  • Emerging themes were identified to bridge research evidence and practical application.

Main Results:

  • Three promising KT intervention types were identified: community-based health education, lay or peer health education, and targeted or tailored interventions.
  • Each intervention type is presented with examples, key themes, and considerations.
  • The review synthesizes evidence to inform intervention selection.

Conclusions:

  • Community-based, lay/peer, and targeted health education interventions show promise for increasing cancer screening participation.
  • A decision tool is provided to assist KT and implementation teams in selecting appropriate interventions.
  • Interventions can be adapted to specific local contexts for successful implementation.

Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Preventive Healthcare Services01:30

Preventive Healthcare Services

Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:
Levels of Health Promotion and Illness Prevention01:26

Levels of Health Promotion and Illness Prevention

Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

Role of Communication in the Nursing Process II: Planning and Implementation

Several factors are considered while creating a patient's care plan. Motivation is a factor in improving communication, and patients often require encouragement to try different approaches involving significant change. It is essential to involve the patient and family in decisions about the plan of care to determine whether the suggested methods are acceptable. Consider meeting critical comfort and safety needs before introducing new communication methods and techniques. Allow adequate time for...

Nursing Interventions II: Selecting and Classifying the Nursing Interventions

Creating and executing a nursing diagnosis helps nurses plan care and guide patient, family, and community interventions. They are developed based on a patient's physical evaluation and support measuring the outcomes. It is not recommended to select random interventions throughout the planning process. Instead, consider the following six essential factors when choosing interventions:
Cancer Survival Analysis01:21

Cancer Survival Analysis

Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
