Characterization of Individuals Taking Part in Low Dose Computed Tomography (LDCT) Screening Program.

UNLABELLED: In the past years the participation rate in conventional voluntary x-ray lung screening has been around 22 % in Somogy County in Hungary. Due to the high morbidity and mortality rates of lung cancer, low participation rate of the high risk individuals on the screening is a primary question in Hungary. To obtain an effectively high level of participation in our ongoing low dose CT screening program, we had to emphasize the benefits of participation for the targeted individuals. As a first step, our aim was to gather information on the aspects affecting the individuals' will for participation. We used the most accessible source of information: individuals over the age of 50, who attended the conventional voluntary lung screening, were approached to fill a questionnaire on their habits relating to smoking, health issues and their prior participation of lung screening. 1080 adults anonymously completed the questionnaire. Analyzing the results, beside other findings, we found a unique variable factor, which altered negatively the compliance for the screening: older individuals, who started participating in the screening in obligation to the health regulations, took part in the voluntary screening programs at a significantly lower rate. Our findings led us to better understanding the complexity of decision making affecting the individual's participation and attitudes toward health issues. TRIAL REGISTRATION: IG/03833/2012.

[Preliminary experiences with low-dose computed tomography for lung cancer screening in Hungary]. / Alacsony dózisú CT-vel történo tüdorákszurés magyarországi bevezetésének elso tapasztalatai.

INTRODUCTION: Lung cancer has the highest mortality rate of all types of cancers both in developed countries and Hungary. AIM: To obtain experience and facilitate the application of low-dose computed tomography-based lung cancer screening as a targeted public health screening procedure. METHOD: Volunteers without thoracic complaints above the age of 40 years (n = 963) were screened for lung cancer using digital chest radiography and low-dose computed tomography. RESULTS: Two lung cancers were found among the participants screened with digital chest radiography (0.2%). After informed consent, 173 individuals with normal chest radiography findings (n = 943) took the opportunity to voluntarily participate in low-dose computed tomography screening for lung cancer. After 3 or 12 months, 65 individuals had follow up control examinations based on the size and characteristics of the detected lesions. Among them, one participant was found to have lung cancer using low-dose computed tomography. CONCLUSIONS: These results indicate that low-dose computed tomography-based lung cancer screening as a public health screening procedure can enhance the success of screening with 50% (from 0.2% to 0.3%). The cost-benefit ratio can be raised if chest radiography is performed prior to the low-dose computed tomography examination.

First result of differentiated communication--to smokers and non-smokers--in order to increase the voluntary participation rate in lung screening.

BACKGROUND: Lung cancer is the most common fatal malignancy and also the primary cause of cancer mortality. Participation in lung screening is an important step in diagnosing patient in early stage and it can promise better outcomes. The aim of this preliminary study was to determinate the differences in the participation rate of smokers and non-smokers in lung cancer screening and to determine the communication strategies to increase the participation rate. METHODS: In the given period of time (from May to August 2012) out of 1426 people who participated in the lung screening program 1,060 adult volunteers (331 males and 729 females, average age 54.0 ± 9.3 years), completed fully and anonymously author's questionnaire that contained 28 questions. 25.7% of the respondents were smokers (n=272), 64.6% have never smoked, while 9.7% were former smokers. RESULTS: Mostly former smokers considered lung screening as an effective method for early detection of pulmonary diseases (86.4%). The most important source (41.0%) of information was the general practitioner. The participation rate of non-smokers is higher in lung screening than the ratio of non-smokers in the population. The unclear data suggest that smokers need distinct, concise messages to know why they should regularly undergo lung screening and doctors have a major role in this. CONCLUSIONS: We found that smokers significantly more frequently took part in lung screening annually. It is positive that the participation rate of former smokers is higher than non-smokers, it is just a bit lower than the participation rate of smokers--both in annual and biannual participation. The participation rate of non-smokers is higher in lung screening than the rate of non-smokers in the population.
