  • Background: Colorectal cancer is a major cause of morbidity and mortality throughout the world. Colorectal cancer screening is an optimal way for reducing of morbidity and mortality and a clinical decision support system (CDSS) plays an important role in predicting success of screening processes. DSS is a computer-based information system that improves the delivery of preventive care services. The aim of this article was to detail engineering of information requirements and work flow design of CDSS for a colorectal cancer screening program. Materials and Methods: In the first stage a screening minimum data set was determined. Developed and developing countries were analyzed for identifying this data set. Then information deficiencies and gaps were determined by check list. The second stage was a qualitative survey with a semi-structured interview as the study tool. A total of 15 users and stakeholders' perspectives about workflow of CDSS were studied. Finally workflow of DSS of control program was designed by standard clinical practice guidelines and perspectives. Results: Screening minimum data set of national colorectal cancer screening program was defined in five sections, including colonoscopy data set, surgery, pathology, genetics and pedigree data set. Deficiencies and information gaps were analyzed. Then we designed a work process standard of screening. Finally workflow of DSS and entry stage were determined. Conclusions: A CDSS facilitates complex decision making for screening and has key roles in designing optimal interactions between colonoscopy, pathology and laboratory departments. Also workflow analysis is useful to identify data reconciliation strategies to address documentation gaps. Following recommendations of CDSS should improve quality of colorectal cancer screening.

  • Background: A contamination screening process for the local population in radiation emergencies is discussed. Materials and Methods: We present an overview of the relevant Korean governmental regulations that underpin the development of an effective response system. Moreover, case studies of foreign countries responding to mass casualties are presented, and indicate that responses should be able to handle a large demand for contamination screening of the local public as well as screening of the immediate victims of the incident. Results and Discussion: We propose operating procedures for an off-site contamination screening post operated by the local government for members of the public who have not been directly harmed in the accident. In order to devise screening categories, sorting strategies assessing contamination and exposure are discussed, as well as a psychological response system. Conclusion: This study will lead to the effective operation of contamination screening clinics if an accident occurs. Furthermore, the role of contamination screening clinics in the overall context of the radiation emergency treatment system should be clearly established.

  • Objectives: To investigate the current prevalence and knowledge of cervical cancer, breast cancer and reproductive tract infections (RTIs) in rural Chinese women, and to explore the acceptance and feasibility of implementing a combined screening program in rural China. Methods: A population-based, cross-sectional study was conducted among women aged 30 to 59 years old in Xiangyuan County, Shanxi Province from 2009 to 2010. Socio-demographic characteristics, knowledge of cervical cancer, breast cancer and RTIs, and the attitude toward single or combined screening were collected by an interview questionnaire. Each participant received a clinical examination of the cervix, breast and reproductive tract. Examinations included visual inspection, mammography, laboratory tests and pathological diagnosis. Results: A total of 1,530 women were enrolled in this study. The prevalence of cervical precancerous lesions, suspicious breast cancer, suspicious benign breast disease and RTIs was 1.4%, 0.2%, 14.0% and 54.3%, respectively. Cervicitis, trichomonas vaginitis, and bacterial vaginitis were the three most common RTIs among our participants. Television, radio broadcast, and public education during screening were the major source of healthcare knowledge in rural China. Moreover 99.7% of women expressed great interest in participating in a combined screening project. The affordable limit for combined screening project was only 50 RMB for more than half of the rural women. Conclusion: A combined screening program would be more effective and popular than single disease screening projects, while appropriate accompanied education and a co-pay model for its successful implementation need to be explored, especially in low-resource settings.

  • Economic decision models are being increasingly used to assess medical interventions. Advances in this field are mainly due to enhanced processing capacity of computers, availability of specific software to perform the necessary tasks, and refined mathematical techniques. We here estimated the incremental cost-effectiveness of ten strategies for colon cancer screening, as well as no screening, incorporating quality of life, noncompliance and data on the costs and profit of chemotherapy in Iran. We used a Markov model to measure the costs and quality-adjusted life expectancy of a 50-year-old average-risk Iranian without screening and with screening by each test. In this paper, we tested the model with data from the Ministry of Health and published literature. We considered costs from the perspective of a health insurance organization, with inflation to 2011, the Iranian Rial being converted into US dollars. We focused on three tests for the 10 strategies considered currently being used for population screening in some Iranians provinces (Kerman, Golestan Mazandaran, Ardabil, and Tehran): low-sensitivity guaiac fecal occult blood test, performed annually; fecal immunochemical test, performed annually; and colonoscopy, performed every 10 years. These strategies reduced the incidence of colorectal cancer by 39%, 60% and 76%, and mortality by 50%, 69% and 78%, respectively, compared with no screening. These approaches generated ICER (incremental cost-effectiveness ratios) of $9067, $654 and $8700 per QALY (quality-adjusted life year), respectively. Sensitivity analyses were conducted to assess the influence of various scales on the economic evaluation of screening. The results were sensitive to probabilistic sensitivity analysis. Colonoscopy every ten years yielded the greatest net health value. Screening for colon cancer is economical and cost-effective over conventional levels of WTP8.

  • Background: Increasing knowledge and awareness of cancer screening significantly influence health promotion behavior which could markedly reduce incidence rates. In many countries, health care providers are the principal source of information concerning cancer screening. This study was carried out to assess the level of knowledge concerning cancer screening among medical students, house officers and residents and to explore their attitude towards cancer screening practices. Materials and Methods: This cross-sectional study was conducted in Kasr Al Ainy Medical School at Cairo University in Egypt, with 300 undergraduate medical students and 150 postgraduates (interns and residents) enrolled. A pre-tested self-administered questionnaire was used to collect data from the study participants regarding personal and education-related information, knowledge about cancer screening and its sources, and attitude towards cancer screening. Results: More than 64% of participants had knowledge scores of ${\leq}10$ points (out of 24). The total knowledge score (out of 6 points) for breast cancer screening increased from $1.9{\pm}1.0$ to $2.3{\pm}1.2$ and $2.4{\pm}1.1$ for $4^{th}$, $5^{th}$ and $6^{th}$ year respectively, interns showed the highest score of $2.6{\pm}1.1$, P= 0.001. Year of enrollment at medical school was a significant positive predictor of acquiring knowledge about cancer screening (post graduate vs. undergraduate students) (OR= 1.30, C.I =1.01-1.63), lack of or none receiving of orientation/training about cancer screening was the sole negative significant predictor for proper knowledge about cancer screening (OR=0.50, C.I=0.31-0.82). Over 92% of students agreed that they had insufficient knowledge about cancer screening, 88.2% appraised the need to have enough knowledge in order to direct/advice patients, relatives and friends, and 93.7% required that the faculty should emphasize the importance of cancer screening in the delivered curricula at medical school. Conclusions: A relatively low to moderate level of knowledge about cancer screening was detected among the selected medical students regardless of their year of enrollment at medical school or their graduation status, which may implicate a negative impact on early cancer detection especially in a low resource country like Egypt.

  • Background: Fear and fatalism have been proposed as factors affecting breast cancer screening, but the evidence is not strong. This study aimed to determine relationships of fear and fatalism with breast cancer screening behavior among Tabriz women in Iran. Materials and Methods: In a cross- sectional study, 370 women referred to 12 health centers in Tabriz were selected with two-stage cluster sampling and data regarding breast cancer screening, fatalism and fear of breast cancer were collected respectively with a checklist for screening performance, Champions Fear and Pow Fatalism Questionnaires. Data were analyzed by logistic regression with SPSS software version 16. Results: Only 43% and 23% of participants had undergone breast self- examination and clinical breast examination. Among women older than 40 years, 38.2% had mammography history and only 2.7% of them had done it annually. Although fatalism and fear had a stimulating effects on breast cancer screening performance th relationships were not significant (P>0.05). There was a negative significant correlation between fear and fatalism (r= -0.24, p=0.000). On logistic regression analysis, age (OR=1.037, p<0.01) and income status (OR= 0.411, p<0.05) significantly explained BSE and age (OR=1.051, p<0.01) and body mass index (OR= 0.879, p<0.01) explained CBE. Also BMI (OR= 0.074, p<0.05) and income status (OR=0.155, p<0.01) was significantly effective for mammography following. Conclusions: Breast cancer screening behavior is inappropriate and affected by family livelihood status and lifestyle leads to weight gain, so that for promoting of screening behaviors, economic support to families, lifestyle modification and public education are suggested.

  • Background: The principal aim of health service providers in the field of breast cancer is to detect and treat lesions at an appropriate time. Therefore, identification of barriers to screening can be very helpful. The present study aimed to systematically review the qualitative studies for extracting and reporting the barriers of screening for breast cancer from the womans perspective. Materials and Methods: In this systematic review; Pubmed, Google Scholar, Ovid Scopus, Cochrane Library, Iranmedex, and SID were searched using the keywords: screening barriers, cancer, qualitative studies, breast and their Persian equivalents, and the needed data were extracted and analyzed using an extraction table. To assess the quality of the studies, the Critical Appraisal Skills Programme (CASP) tool was used. Results: From 2,134 related articles that were found, 21 articles were eventually included in the study. The most important barriers from the point of view of 1,084 women were lack of knowledge, access barriers (financial, geographical, cultural), fear (of results and pain), performance of service providers, women's beliefs, procrastination of screening, embarrassment, long wait for getting an appointment, language problems, and previous negative experiences. Articles' assessment score was 68.9. Conclusions: Increasing women's knowledge, reducing the costs of screening services, cultural promotion for screening, presenting less painful methods, changing beliefs of health service providers, provision of privacy for giving service, decreasing the waiting time, and providing high quality services in a respectful manner can be effective ways to increase breast cancer screening.

  • Background: According to recent statistics, the breast cancer rate is growing fast in developing countries. In North West of Iran, the incidence of breast cancer after esophageal and gastric cancers has the highest rate. Previous studies have also indicated that women in this region show reluctance to do breast cancer screening. There is a great need for change to promote breast cancer screening among women. Social marketing is a discipline that uses the systematic application of commercial marketing techniques to promote the adoption of behavior by the target audience. Materials and Methods: In the present qualitative study, thirty-two women with breast cancer were interviewed about their experiences of breast cancer screening. A semi-structured interview guide was designed to elicit information specific to the 4 P's in social marketing. Results: Three main categories emerged from the analysis: price, service and promotion. Subcategories related to these main categories included factors effective in increasing and decreasing cost of screening, current and desirable features of screening services, and weakness of promotion. Conclusions: Screening programs should be designed to be of low cost, to meet patients' needs and should be provided in suitable places. Furthermore, it is essential that the cultural beliefs of society be improved through education. It seems necessary to design an executive protocol for breast cancer screening at different levels of primary health care to increase the women's willingness to undergo screening.

  • Background: The majority of women in rural India have poor or no access to cervical cancer screening services, although one.quarter of all cervical cancers in the world occur there. Several large trials have proven the efficacy of low-tech cervical cancer screening methods in the Indian context but none have documented the necessary components and processes of implementing this evidence in a low-resource setting. Methods: This paper discusses a feasible model of implementation of cervical cancer screening programme in low-resource settings developed through a pilot research project carried out in rural Tamilnadu, India. The programme used visual inspection of cervix after acetic acid application (VIA) as a screening tool, nurses in the primary care centres as the primary screeners and peer educators within Self-Help Women groups to raise community awareness. Results: The uptake of screening was initially low despite the access to a screening programme. However, the programme witnessed an incremental increase in the number of women accessing screening with increasing community awareness. Conclusions: The investigators recommend 4 key components to programme implementation in low-resource setting: 1) Evidence-based, cost-effective test and treatment available within the reach of the community; 2) Appropriate referral pathways; 3) Skilled health workers and necessary equipment; and 4) Optimisation of health literacy, beliefs, attitudes of the community.
