Psychosocial safety climate (PSC) is increasingly recognised as an important organisational resource for promoting mental health at work and preventing psychosocial risks, which are aspects of work design, organisation and management that could threaten employees' psychological or physical well-being. While substantial theoretical and empirical evidence supports the role of PSC as a protective factor, limited research has explored how PSC can be deliberately and sustainably enhanced through organisational interventions. This scoping review aims to map PSC-related interventions, synthesise how PSC is conceptualised and operationalised, and identify elements that studies have reported as contributing to strengthening PSC.

This scoping review will follow established methodological frameworks and Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines to systematically identify and synthesise studies describing organisational interventions related to PSC. A comprehensive search strategy will be implemented across several databases, including MEDLINE, PsycINFO, Web of Science, ABI/INFORM and Business Source Premier. Eligible studies must describe, implement or evaluate interventions explicitly targeting PSC. Data on intervention types, mechanisms, outcomes and contextual factors will be extracted and narratively synthesised to address the descriptive research questions and map how PSC interventions have been conceptualised and implemented across organisational contexts. This protocol does not involve human participants. The review is not yet registered. Findings will inform future research and organisational practices related to PSC-focused interventions.

This review involves analysis of published literature only and does not require ethics approval. Findings will be submitted to a peer-reviewed journal and presented at relevant academic and professional conferences. Results will be reported in accordance with the PRISMA-ScR guidelines and will inform the development of future organisational interventions aimed at enhancing PSC.

This project aimed to assess the applicability of the National Institute for Health and Care Research (NIHR) tool to French academic studies and identify the carbon hotspots, with a view to discussing ways of mitigating their environmental impact.

Retrospective analysis.

A completed single-centre phase I haematology trial TOCILAM (NCT04547062) and a completed multicentre phase III in intensive care REMICRUSH (NCT03960801).

TOCILAM had a total number of 12 participants and REMICRUSH had a total number of 1150 participants.

Total carbon emissions from each trial and the hotspots of those emissions.

The carbon footprint of the TOCILAM and REMICRUSH studies was estimated at 3.2 and 5.8 tonnes of CO₂ equivalent, respectively. For these two studies, the hotspots were the Meetings and travel item followed by the clinical trial unit emissions.

The NIHR tool is easily applicable to the context of French academic clinical studies. The total estimated carbon footprint of the two clinical trials was generally lower than what has been reported in the literature for academic studies. However, areas for improvement have been identified.
