'Dialogue and Guidance' - a Policy Intervention for Improved OHS Among Workplaces With WEA Violations

With the aim to inspire and motivate workplaces in their work to prevent and reduce occupational health and safety hazards, the Danish Working Environment Authority (WEA) developed the intervention 'Dialogue and Guidance' aimed at workplaces receiving notices (prohibition notice, immediate improvement notice and notice with time limit) from WEA during inspections. At present, WEA gives dialogue and guidance as standard practice during WEA inspections to all workplaces receiving a notice with the purpose to help workplaces resolve the occupational health and safety problem that led to the notice. In the intervention 'Dialogue and Guidance' the experimental groups are receiving additional dialogue and guidance at a subsequent meeting (over the telephone or physical presence) that takes place after the inspection and after the deadline for appealing the notice has expired. The control group is receiving dialogue and guidance during inspection as usual. The aim of this RCT study is to evaluate the policy-developed intervention with additional 'Dialogue and Guidance' in regards to the effect on motivation and priority of occupational health and safety work at the workplace after 6 months follow-up and for WEA notices by next WEA inspection (approx. follow-up by 12-18 months). Study is risk assessed and approved under Danish Data Protection Agency via the National Research Centre for the Working Environment's umbrella approval.

Safety of PET MPI Using the CRCHUM N-13 Ammonia

Positron emission tomography (PET) myocardial perfusion imaging (MPI) is an examination that helps to assess the function and perfusion of the heart. Completion of this examination requires the injection of a small dose of a radiotracer (a radioactive substance). PET MPI is a state-of-the-art non-invasive cardiac imaging tool. The main goal of the PET MPI examination is to assess if one or more of the arteries feeding blood to your heart are blocked. This examination replaces an older technology (single photon emission computed tomography, or SPECT), and allows the obtention of more accurate information, and new information that the older SPECT technology did not assess. The radiation dose received as part of the procedure is also smaller with PET versus SPECT. One of the substances which can be used for PET MPI is called N-13 ammoniac (NH3). For this clinical study, NH3 which will be produced at the Centre de Recherche du Centre Hospitalier de l'Université de Montréal (CRCHUM), per the standards and methods prescribed by Health Canada. NH3 is not currently approved for clinical use by Health Canada. It is thus considered and experimental substance in the context of this study. Participants will undergo PET MPI with the CRCHUM NH3. The PET MPI procedure itself is not an experimental procedure and is not part of the research protocol. Only the use of NH3 produced at the CRCHUM is experimental. The main objective of this research study is to validate the production process and assess the safety of the NH3 produced at the CRCHUM cyclotron. Secondary objectives include the assessment of prescription practices amongst physicians who refer patients for PET MPI, and how they will change over time.
