Delphi consensus on the monitoring tools of main individual risk factors for chronic diseases by the company doctor. / Ricerca di consenso Delphi sugli strumenti per il monitoraggio da parte del medico competente dei principali fattori di rischio individuali per malattie croniche.

BACKGROUND: Data on individual risk factors for chronic diseases (smoking, physical activity, body mass) are collected by company physicians in heterogeneous ways. This makes comparisons, researches and evaluations difficult. OBJECTIVES: The aim of the study was to find a consensus on evaluation tools for chronic diseases risk factors and for health promotion programs in workplaces that could be performed by company physicians during their clinical activity. METHODS: A first set of tools, proposed by a working group of occupational physicians in Bergamo, was submitted through the Delphi technique to a national expert panel of 22 persons including recognized national experts in specific fields and occupational physicians skilled in health promotion. RESULTS: In three Delphi rounds, the panel selected a set of tools to monitor the main individual risk factors for chronic diseases (smoking, alcohol, physical activity, nutrition, stress and mental health) as well as general data related to the worker and his job. CONCLUSIONS: The use of these specific tools, collected in a homogeneous format, should be recommended to all Italian company physicians, in particular those who work in WHP-programs, in order to allow analysis, comparison and evaluation of health promotion programs effectiveness at a national level.

[Assessment of the impact over one year of a workplace health promotion programme in the province of Bergamo]. / Stima dell's effecto ad un anno di un programma di promozione della salute nei luoghi di lavoro in provincia di Bergamo.

OBJECTIVES: To estimate short-term effects of integrated health promotion in the workplace within the framework of the Bergamo WHP (Workplace Health Promotion) network, which involves 94 companies and about 21,000 workers. METHODS: A controlled non-randomized, before-after evaluation was carried out. Data were collected through anonymous questionnaires before (t0) and after participation in a 12-month health promotion programme (t1). The "control" group consisted of workers of companies participating in the programme who had not yet undertaken any interventions in the theme areas covered by the assessment. RESULTS: In the workers participating in the programme, positive early effects (after 12 months) were related to intake of food providing protection (fruit and vegetables) and increased rates of smoking cessation. The effects were more evident in males and in white collars. The physical activity and alcohol consumption trends went in the desired direction and with more effects than in the non-participating group, but without statistical significance. In the short term, no evident changes in events of road injury risk or in the quality of personal relationships were seen, probably due to the small size of the sample involved in these study areas. CONCLUSIONS: The results, although within the methodological limitations of the study, showed that after 12 months there was a reduction in some important risk factors for chronic diseases in workers participating in the programme, particularly for fruit and vegetable intake and smoking cessation. It will be important to monitor the effects of the programme on other risk factors in the medium and long term, and also the impact of employment status and gender so as to adjust the programme interventions accordingly. Cooperation with occupational/authorized physicians with use of their data collected from health surveillance, together with a limited set of general risk factor indicators, would be a desirable development for further studies.

Improved 5-year survival of patients with immunochemical faecal blood test-screen-detected colorectal cancer versus non-screening cancers in northern Italy.

BACKGROUND: Colorectal cancer screening may reduce disease-related mortality by early-stage detection of cancers. AIMS: To study the effect of a single immunochemical faecal occult blood test (i-FOBt) screening round on reduction in colorectal cancer-related-mortality among average risk subjects. METHODS: Comparison of 5-year mortality rates in 3 cohorts from a Northern Italian province: (1) colorectal cancers detected at the 1st biennial round of a mass-screening programme targeting 50-69 years old subjects, (2) non-screening cancers symptomatically diagnosed during the same time period, and (3) cancers detected in the pre-screening biennium. Multivariate analyses were performed with the Cox regression model including tumour node metastasis (TNM) stage at diagnosis, anatomical distribution of cancers, age at diagnosis, gender and patient group. Kaplan-Meyer survival estimates and log-rank test for equality of survivor functions were calculated. RESULTS: Stage distribution significantly differed between screening and non-screening colorectal cancers: 73% of screen-detected colorectal cancers were stages I and II versus 43% and 40% of non-screening and pre-screening colorectal cancers. Cumulative 5-year mortality rate was significantly lower in screening compared to non-screening or pre-screening colorectal cancers patients (19% versus 37% and 41%, p < 0.001). CONCLUSIONS: Colorectal cancers were detected at earlier stages in i-FOBT-positive subjects in comparison with non-screening patients; colorectal cancers found at screening had a significantly improved 5-year survival.

A combination of faecal tests for the detection of colon cancer: a new strategy for an appropriate selection of referrals to colonoscopy? A prospective multicentre Italian study.

INTRODUCTION: Colonoscopy workload for endoscopy services in Western countries is increasing markedly because of the implementation of faecal occult blood-based mass screening programmes against colorectal cancer (CRC). We therefore explored the possibility of using a combination of faecal tests to prioritize the access to colonoscopy with criteria other than symptoms and/or time of referral. AIMS AND METHODS: We tested a combination of faecal tests [immunochemical faecal occult blood test (i-FOBT), M2-PK, calprotectin] as markers for advanced neoplasia in a selected series of patients requiring colonoscopy for the suspicion of CRC. All the tests were performed in a 1-day stool sample of patients aged 50-80 years, without any dietary restriction, before colonoscopy. RESULTS: A total of 280 patients' stool single samples were analysed. Forty-seven patients had CRC and 85 patients had one or more advanced adenoma(s) at colonoscopy/histology. CRCs were associated with a highly significant increase (P<0.001) in faecal tumour M2-PK (mean 24.2 kU/l), which correlated with Dukes' staging. For CRC detection, i-FOBT was the test with the highest specificity and positive predictive value (0.89 and 0.53), whereas M2-PK had the highest sensitivity and negative predictive value (0.87 and 0.96). Calprotectin showed performance similar to M2-PK in terms of sensitivity and negative predictive value (0.93), but had lower specificity (0.39). The best combination of tests to predict the risk of CRC in this series was i-FOBT+M2-PK, as in patients showing positivity to both markers, the risk of cancer was as high as 79%. CONCLUSION: The combination of i-FOBT and M2-PK is a sensitive tool in clinical practice for the appropriate management of waiting lists for colonoscopy, as it allows the classification of patients into different degrees of priority for investigation, according to their foreseeable risk of CRC.

[Workplace health promotion: description and preliminary results of ASL of Bergamo integrated]. / Promuovere la salute in azienda: descrizione e primi risultati di un intervento interdiscliplinare dell'ASL di Bergamo.

Interventions for health promotion in the workplace (WHP programs) can improve the health of workers, acting on modifiable risk factors for chronic diseases. The effectiveness of integrated programs of health promotion in companies is well described in literature. Our project was conducted in two mid-sized companies in the province of Bergamo, respectively with 170 and 230 employees. The project issues were in the following areas: tobacco smoke (awareness and support to smoking cessation); nutrition (awareness and practical action on the workplace canteen); physical activity (awareness, information and practical ways of incentives); prevention of road accidents (training and initiatives to promote safety). The analysis of the behaviours and individual risk factors was performed by a questionnaire at the beginning of the project and a year later. 95 initial questionnaires were returned and processed for the company A and 168 for the company B; their results were discussed with company management, the company doctors and workers representatives and allowed the formulation of a "company assessment risk profile" according to the methodology of the Assessment of Health Risks with Feedback (AHRF). There have been training/awareness messages in working hours for all employees on areas of lifestyle and have started work on the canteen, actions to promote road safety, physical activity and interventions to counter the smoking. The effectiveness of group treatments for smoking cessation has been of 55.6% at 3 months and 50% at 6 months (at the present only a company has achieved 6 months of follow up).

Impact of a population-based colorectal cancer screening program on local health services demand in Italy: a 7-year survey in a northern province.

OBJECTIVES: In 2005, the National Health Service recommended a population-based colorectal cancer (CRC) screening program using biennial fecal occult blood testing (FOBT), followed by total colonoscopy in positive patients. So far, no studies have been performed to evaluate the impact of a mass-screening CRC campaign on the health system services at the community level in Italy. We have therefore assessed the workload generated by the first two biennial rounds of screening program on the activity of hospital services involved in CRC diagnosis in the Lecco province. METHODS: Routine data from all hospital services of our province were collected on activity levels related to CRC diagnosis from January 2003 to December 2009. This time span covered the 2 years prior to, as well as the two biennial rounds of the CRC screening program. In particular, we focused on the volume of outpatient FOBTs and colonoscopies (both diagnostic and interventional) performed among subjects outside the screening program. Joinpoint models were used to test whether an apparent change in trend of examination over time was statistically significant in different age cohorts of the population (<50 years, 50-69 years, and ≥70 years). RESULTS: The volume of "extra-screening" per-patient/FOBTs and colonoscopies increased significantly over the evaluated periods in all ages, until year 2008, when a steady trend was beginning; the AAPCs (average of the annual percent changes) values were 5.7, 3.1, and 8.4 for FOBT and 14.6, 13.4, and 16.7 for colonoscopy in the three age cohorts, respectively. However, the increase in both FOBT and colonoscopy demand was maximal in the cohort ≥70 years, where three statistically significant annual percent changes (APCs) were identified (in 2003-2005, 2005-2006, and 2006-2007 APCs were 12.3, 14.9, and 15.9 for FOBT, and 18.7, 36.8, and 25.4 for colonoscopy, respectively). CONCLUSIONS: After the implementation of a FOBT-based mass-screening program for CRC, careful consideration must be given to the significant increase in the workload of hospital services involved in CRC diagnosis, outside the screening campaign. The extra-work mainly involves gastroenterologists performing colonoscopy, whose activity increased over the 5-year period by 118%, as well as laboratory services, where the demand of FOBTs rose by 40%. This phenomenon, mainly attributable to a profound change in the attitude toward CRC screening by those age cohorts outside the program, covers a time span of two full rounds of screening, whereupon a steady trend for colonoscopy is apparent.
