Workplace colorectal cancer-screening awareness programs: an adjunct to primary care practice?

Effectiveness of workplace cancer screening interventions: a systematic review

INTRODUCTION

Cancer cases are rising globally, with a noticeable rise in younger adults. Screening and early detection are effective in decreasing mortality. Workplaces can play a role in promoting cancer screening uptake. This systematic review investigated the effectiveness of workplace breast, lung, colorectal, and cervical cancer screening interventions, and the factors impacting their effectiveness.

METHODOLOGY

Six databases (Embase, Medline, Web of Science, CINAHL, Cochrane Library, Scopus) were searched, and cancer screening promotion and cancer screening uptake was analysed using effect direction plots. Magnitude of effectiveness (i.e., change in knowledge or screening rate) was also evaluated.

RESULTS

In total, 13,426 articles were identified. After screening and applying the eligibility criteria, 21 articles were included in the analysis. A positive effect direction was seen for all workplace cancer screening promotion interventions. Magnitude of effectiveness for cancer screening promotion interventions resulted in a > 30% change in knowledge or screening uptake in 4/7 of breast cancer, in 3/4 of cervical cancer and 1/3 colorectal cancer screening promotion interventions. For workplace cancer screening uptake interventions, a positive effect direction was observed for the majority (18/22). Cancer screening uptake interventions showed a > 30% change in magnitude of screening rate in 4/7 breast cancer, 5/10 colorectal cancer and in 1/5 cervical cancer workplace interventions. No studies for lung cancer were eligible. Factors positively influencing effectiveness included an interest in health and previous healthcare use, while fear of cancer and embarrassment of screening negatively influenced effectiveness.

CONCLUSION

Workplace cancer screening promotion and uptake interventions can effectively improve cancer screening knowledge and increase uptake of screening tests.

Creating a Workplace Culture of Preventive Health: Process and Outcomes of the Colon Cancer-Free Zone at Virginia Cooperative Extension

Colorectal cancer is the third leading cause of cancer death in the USA, yet is highly preventable and detectable at an early stage through screening. Virginia Cooperative Extension (VCE) implemented a worksite colon cancer awareness program to increase colorectal cancer screening rates and preventive lifestyle behaviors among its employees. The Colon Cancer-Free Zone program is designed using best practice principles of worksite health programs and includes information sessions covering the topics of colorectal cancer, screening guidelines, insurance coverage, and preventive lifestyle behaviors. It is conducted in a campaign format that includes a strategic communication strategy targeting relevant screening barriers and facilitators, peer champions, and incentives. The program was implemented with VCE employees statewide utilizing a web-based system for the information sessions, and resulted in broad participation, a significant increase in screening self-efficacy (4.15 ± 0.64 vs 3.81 ± 0.76, ρ = 0.006), changes in diet and physical activity (50% and 40% of participants, respectively), and a 20.6% increase in the employee colorectal cancer screening rate. A Colon Cancer-Free Zone toolkit was developed for use by Extension Agents to implement the program at worksites in their service communities.

Awareness of Colorectal Cancer among the Urban Population in the Klang Valley

BACKGROUND

Colorectal cancer (CRC) is the second most common cancer in Malaysia. Awareness of risk factors, symptoms and warning signs of CRC will help in early detection. This paper presents the level of CRC awareness among the urban population in Malaysia.

METHOD

A cross-sectional study was conducted from November 2015 till December 2016 at three government clinics in the Klang Valley. The validated Bowel Cancer Awareness Measure questionnaire in both English and Malay was used. The mean knowledge scores for the warning signs and risk factors of CRC in different socio-demographic groups were compared using ANOVA in SPSS version 23. Statistical significance was set at p<0.05 and a 95% confidence level.

RESULTS

Of the 426 respondents, 29.1% were unable to recall the warning signs and symptoms of CRC. Average recall was less than two warning signs and symptoms (mean 1.62, SD 1.33). The mean total knowledge score for CRC was 9.91 (SD 4.78), with a mean knowledge scores for warning signs and risk factors at 5.27 (SD 2.74) and 4.64 (SD 2.78), respectively. Respondents with a higher level of education were found to have higher level of knowledge regarding the warning signs of CRC. There was a significant positive association between knowledge score for warning signs and level of confidence in detecting warning signs. Regarding the total knowledge score for CRC, 3.3% of respondents scored zero. For warning signs and risk factors, 8.2% and 8.5% of respondents had zero knowledge scores, respectively.

CONCLUSIONS

Generally, awareness of CRC is poor among the urban population of Klang Valley. Greater education and more confidence in detecting warning signs are significantly associated with better knowledge of warning signs. CRC awareness programs should be increased to improve awareness.

Awareness of colorectal cancer among public in Asir region

Introduction:

Colorectal cancer (CRC) has different forms of colon cancer or rectal cancer. CRCs are often considered together because they possess many similar features. A severe form of the disease with higher mortality rate increases with increase in age. The most common CRC risk factors include smoking, diabetes, and obesity. This study aims to evaluate the awareness of CRC in a random population of Asir region and to identify the subpopulation that can be recipients of awareness and screening programs.

Material and Methods:

Cross-sectional nonprobable random sampling study using a self-administered questionnaire survey which was employed to include healthy males and females from Asir region. The questionnaire included ten questions in Arabic language and data were categorized according to gender, marital status, age, and level of education to determine whether these demographic groups possess difference in knowledge about CRC.

Results:

Most of the respondents (51% and 71.6%) knew what is colon and rectum. About 33.8% know the correct function of the colon while 22.5% know the correct incidence and 22.1% know the correct time of screening for CRC. Very few respondents know the symptoms, risks, and screening modalities of CRC. Pearson's Chi-square test was employed to evaluate the differences in responses in four demographic categories of the study population. P <0.05 was considered as statistically significant

Conclusions:

Single less educated males lack knowledge of CRC. In addition, there is very low awareness of CRC symptoms, risk factors, and screening modalities among the entire surveyed population.

Colorectal Cancer Screening

Colorectal cancer (CRC) is the third most commonly diagnosed cancer worldwide. It is a potentially preventable disease and ideally suited to a screening program. CRC screening is an early detection strategy for occupational health nurses to offer in the workplace. Education and outreach are key components of this intervention. Many test options are available for CRC screening. This article is an integrative literature review that summarizes evidence to support colorectal screening in the workplace, offers screening recommendations from authoritative agencies, and provides guidance for occupational health nurses who plan to implement a screening program. Current screening limitations using fecal occult blood tests are addressed and an inventory of CRC screening activities in select countries is included.

Public awareness of colorectal cancer in Saudi Arabia: A survey of 1070 participants in Riyadh

BACKGROUND/AIMS

The aim of this study was to investigate colorectal cancer (CRC) awareness in healthy individuals in Saudi Arabia in order to identify segments of the population that would most benefit from targeted education programs.

SETTING AND DESIGN

Survey/questionnaire.

PATIENTS AND METHODS

Random, healthy individuals from Riyadh, Saudi Arabia, were approached to participate in a 10-question multiple choice survey about CRC. Data were analyzed by demographic criteria, including age, gender, marital status, and level of education, to determine if members of these groups displayed differential knowledge.

STATISTICAL ANALYSIS

Differences in responses by demographic data were analyzed using Pearson's Chi-square test. A P < 0.05 was considered statistically significant.

RESULTS

In total, 1070 participants completed the survey. Most respondents believe that screening for colon cancer should begin at symptom onset (42.9%). Less than 20% of all respondents believe that polyps are a risk factor for CRC, which varied significantly according to level of education; however, even the most educated answered correctly less than 50% of the time. Similarly, only 34.8% of all respondents knew that a family history of CRC imparted a personal risk for CRC.

CONCLUSIONS

Although older individuals and those with higher education tended to answer questions correctly more often, there were some misconceptions regarding universally accepted screening protocols, symptoms, and general understanding of CRC in Saudi Arabia. A national education/screening program in Saudi Arabia is recommended to improve CRC knowledge.

The epidemiology of cancer among police officers

BACKGROUND

This review summarizes peer-reviewed studies examining cancer risks among police officers. It provides an overview of existing research limitations and uncertainties and the plausible etiologic risk factors associated with cancer in this understudied occupation.

METHODS

Previous cancer studies among police officers were obtained via a systematic review of the MEDLINE, CABDirect, and Web of Science bibliographic databases.

RESULTS

Quality observational studies of cancer among police officers are sparse and subject to limitations in exposure assessment and other methods. Results from three studies suggested possible increased mortality risks for all cancers, and cancers of the colon, kidney, digestive system, esophagus, male breast, and testis, as well as Hodgkin's disease. Few incidence studies have been performed, and results have been mixed, although some associations with police work have been observed for thyroid, skin, and male breast cancer.

CONCLUSIONS

Police are exposed to a mix of known or suspected agents or activities that increase cancer risk. Epidemiologic evidence to date is sparse and inconsistent. There is a critical need for more research to understand the biological and social processes underlying exposures and the suggested disproportionate risks and to identify effective prevention strategies.

Oral Cancer Screening at Workplace in India-One-year Follow-up

Background:

Oral cancer remains the commonest form of cancer and cancer-related deaths among Indian males due to popularity of avoidable risk factors such as tobacco and alcohol use. A workplace oral cancer screening and tobacco cessation study was commenced on World No Tobacco Day 2007 at a chemical industry in rural Maharashtra.

Aims:

The objectives were to screen the employees for oral neoplasia and to correlate it with their tobacco consumption pattern. In addition, the objective was to provide tobacco cessation services at the workplace.

Materials and Methods:

This is an interventional cohort study among 104 employees of a chemical industrial unit in rural Maharashtra. Naked eye examination of the oral cavity was performed for all employees by a doctor irrespective of the tobacco habits at the beginning and at the end of 1 year. In between, the tobacco users were regularly examined during each follow-up.

Statistical analysis used:

Through personal interviews of the participants, data were manually recorded and were transferred to electronic data base. Data analysis was conducted in STATA™ 8.2 on intention to treat basis.

Results and Conclusions:

Among the 104 employees, 50 (48.08%) were current tobacco users at the beginning of the program. Oral precancers were seen exclusively among 20 (40%) tobacco users. After 1 year of workplace tobacco cessation intervention, 80% of oral precancers regressed. This shows that screening of the oral cavity at the workplace is effective when combined with tobacco cessation.

Cancer screening in US workers

Regular cancer screening can prevent the development of some cancers and increase patient survival for other cancers. We evaluated the reported cancer screening prevalence among a nationally representative sample of all US workers with data from the 2000 and 2005 Cancer Screening Supplements of the National Health Interview Survey. Overall, workers with the lowest rates of health insurance coverage (in particular, Hispanic workers, agricultural workers, and construction workers) reported the lowest cancer screening. There was no significant improvement from 2000 to 2005.
