Summary
This summary is machine-generated.Fear of lung cancer diagnosis and screening procedures are key barriers to low-dose CT screening uptake. Clinician recommendation and perceived personal benefit are important facilitators for lung cancer screening attendance.
Area Of Science
- Oncology
- Public Health
- Health Psychology
Background
- Lung cancer remains a leading cause of cancer mortality globally.
- Low-dose CT (LDCT) screening significantly reduces lung cancer mortality by enabling early detection.
- Low uptake of LDCT screening programs limits their public health impact.
Purpose Of The Study
- To systematically review and identify patient-reported barriers and facilitators influencing the intention to undergo and uptake of LDCT for lung cancer screening.
- To categorize identified determinants using the Theoretical Domains Framework (TDF).
Main Methods
- A comprehensive literature search was conducted across three databases and grey literature.
- Inclusion criteria focused on English-language studies (2001-2024) examining patient-reported psychological factors related to first LDCT uptake.
- Extracted determinants were mapped to the 10 domains of the Theoretical Domains Framework (TDF).
Main Results
- Fear, encompassing fear of diagnosis and screening procedures, was the most prevalent barrier (TDF: Emotion).
- Cost, inconvenience, and lack of knowledge were significant environmental and resource-related barriers (TDF: Environmental Context & Resources, Knowledge).
- Clinician recommendation (TDF: Social Influence) and perceived personal benefit (TDF: Beliefs about Consequences) emerged as key facilitators.
Conclusions
- Interventions targeting fear, cost, and inconvenience are crucial for improving LDCT screening uptake.
- Promoting clinician endorsement and highlighting personal benefits can enhance screening participation.
- Theory-based interventions are needed to address identified barriers and facilitators for lung cancer screening programs.

The barriers to effective communication also include cultural barriers, semantic barriers, gender barriers, and time constraints.
Cultural barriers:
Differences in values, beliefs, religion, knowledge, and tradition can significantly impact communication. Awareness of nonverbal cues is critical, especially when conversing with a patient from a different culture. What appears appropriate in one culture may be inappropriate in another.
Semantic barriers:
As a result of their tendency to use...
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...
A model is a theoretical way to understand a concept or an idea. Models can overcome barriers to health regardless of diverse economic and cultural backgrounds. In addition, models make the task easier by providing different ways to approach complex issues. There are two major health promotion models: the health belief model and the health promotion model.
The health belief model (HBM) attempts to predict health-related behavior in specific belief patterns. According to the HBM, a person's...
Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
PFTs involve using a spirometer, a...
The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.
The agent-host-environment model states that disease results...
Besides the pressure difference between the external environment and the lungs, the airflow rate and ease of pulmonary ventilation are also influenced by three other factors: surface tension of the fluid in the alveoli, compliance of the lungs, and airway resistance.
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...
