Abstract

Insights

Interventions significantly improve cancer patients' illness perception (IP) and quality of life. Theory-based, mixed-format interventions are most effective, highlighting the need for tailored strategies for cancer dyads.

Area of Science:

  • Oncology
  • Health Psychology
  • Behavioral Medicine

Background:

  • Illness perception (IP) significantly impacts cancer patients' coping and quality of life.
  • Limited research exists on interventions specifically designed to enhance IP in cancer patients and their caregivers.
  • Understanding effective IP intervention strategies is crucial for improving patient outcomes.

Purpose of the Study:

  • To identify and synthesize intervention strategies for improving illness perception (IP) in cancer patients and/or family caregivers.
  • To evaluate the effectiveness of IP interventions on health outcomes through meta-analysis.
  • To explore optimal IP intervention characteristics via subgroup analyses.

Main Methods:

  • Systematic literature search across eight databases (up to August 2023) and manual screening.
  • Synthesis of IP intervention strategies for cancer populations using the Common Sense Model (CSM).
  • Meta-analysis and subgroup analyses to assess intervention effects on health outcomes and identify optimal strategies.

Main Results:

  • 18 studies were included; 11 underwent meta-analysis. No studies focused on family caregivers' IP.
  • IP interventions demonstrated favorable effects on cancer patients' IP, quality of life, and other outcomes compared to general care.
  • Theory-based and mixed-format interventions showed significantly higher positive effects on IP outcomes than theory-less or single-format interventions.

Conclusions:

  • IP interventions positively impact cancer patients' outcomes, including quality of life.
  • Future interventions should consider individual IP traits and the specific needs of cancer patients and caregivers.
  • Further research and development of IP interventions targeting cancer patient-caregiver dyads are recommended.

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:

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Nursing Ethical Principles II01:27

Nursing Ethical Principles II

Ethical principles are essential in guiding nurses to fulfill their responsibilities, focusing on the quality of nursing care and decision-making. These principles, including autonomy, beneficence, non-maleficence, justice, and fidelity, shape the ethical framework within healthcare settings.
Consider the following scenario, which illustrates how these principles are applied in the care of Mr. John, a fifty-year-old teacher diagnosed with metastatic liver cancer.
Initially, Mr. John's...

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...

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...

Techniques of therapeutic communication I: Active Listening, Sharing Observations, Validation, and Using Touch

The history of therapeutic communication can be traced back to Florence Nightingale, who emphasized the importance of developing trusting relationships with patients. She taught that the presence of nurses with patients results in therapeutic healing.
Therapeutic communication is not the same as social interaction. Social interaction has no goal or purpose and consists of casual information sharing, whereas therapeutic communication has a plan or purpose for the conversation. Therapeutic...
