Application of Guidelines for Medico-professional Supervision of Workers Exposed to Carcinogenic Action of Wood Dust: CERBois Cohort (CERBois)

August 25, 2016 updated by: Central Hospital, Nancy, France

Application of Guidelines for Medico-professional Supervision of Workers Exposed to Carcinogenic Action of Wood Dust: CERBois Cohort. Feasibility Evaluation

The purpose is to evaluate feasibility of medical supervision of professionally active asymptomatic wood workers with questionnaires and nasofibroscopy.

Secondary purposes are:

  • Feasibility evaluation of identification of former and actual professional expositions to wood dust and to various naso-sinusal carcinogenics in case of co-expositions (formaldehyde, chrome, nickel, leather)
  • Description of abnormal symptoms identified by occupational doctor and needing an otorhinolaryngology test
  • Description of results and examinations induced by nasofibroscopy in symptomatic or asymptomatic individuals: counting of naso-sinusal adenocarcinoma cases
  • Evaluation of participation of workers retiring in 2 years after inclusion to medical supervision program
  • Evaluation of information flow among different players
  • Assessment of costs induced by this targeted screening: direct medical costs (screened pathologies, induced additional examinations…) and indirect costs for company (duration of worker absence for transfer, medical and additional examinations).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

44 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
