Work packages
The Stockholm Center for Return to Work is structured into six interconnected work packages. Together, they build the scientific foundation for sustainable return to work, develop and test workplace and primary care interventions, strengthen system coordination and policy, and translate evidence into innovation, education, and long-term implementation.

WP1 – Building the Knowledge Foundation
WP1.1 – Core Indicators for Stay-at-Work and Return to Work (RTW)
WP leader: Emelie Thern
Goal:
Develop harmonised and scientifically grounded indicators that define and measure sustainable return to work and staying at work.
What we will do:
- Develop core indicators applicable at the individual, workplace, healthcare, and societal levels.
- Engage national and international stakeholders through a Delphi process to build consensus.
- Create a foundation for prediction models, benchmarking, follow-up, and policy analysis.
Impact: These indicators provide a shared framework for research, practice, and decision-making, ensuring everyone speaks the same language when it comes to RTW.
WP1.2 – Improved Prediction of RTW
WP Leader: Ellenor Mittendorfer-Rutz
Goal:
Enhance the ability to predict RTW outcomes by integrating advanced data and methods.
What we will do:
- Develop robust prognostic models for RTW.
- Integrate individual, work-related, healthcare, and societal factors.
- Apply advanced epidemiological designs and machine learning methods.
Impact: The results will inform practice, education, and innovation, helping to tailor interventions and improve outcomes for diverse occupational groups.
WP2 – The Workplace Perspective
WP2.1 – Supporting Employers in the stay-at-work RTW processes
WP Leader: Katarina Kjellberg
Goal:
Strengthen employers’ capacity to manage sustainable and effective stay-at-work and RTW processes.
What we will do:
- Study how workplace adaptations are implemented in practice.
- Identify barriers and facilitators for employers in implementing work adaptations.
- Determine which adaptations and supports from employers can prevent sickness absence and promote sustainable RTW.
- Develop practical tools and evidence-based recommendations for employers.
Impact: Empowers workplaces to take an active and informed role in supporting employees’ stay-at-work and RTW.
WP2.2 – Implementing Multifaceted Workplace Strategies
WP Leader: Lydia Kwak
Goal:
Optimise implementation strategies for preventing mental ill-health and supporting sustainable RTW at the workplace.
What we will do:
- Identify effective combinations of implementation components.
- Test strategies in real-world work environments using adaptive study designs.
- Evaluate adherence, cost-effectiveness, and long-term sustainability.
Impact: Delivers scalable and sustainable solutions that work in everyday practice.
WP3 – Primary Care and Healthcare Systems
WP3.1 – RTW Interventions in Primary Care
WP Leader: Anna Finnes
Goal:
Test and evaluate work-oriented interventions for patients with common mental health conditions.
What we will do:
- Combine organisational and patient-level interventions in primary care.
- Conduct hybrid evaluations assessing both effectiveness and implementation.
- Follow outcomes related to health, work ability, and sick leave over time.
Impact: Integrates RTW support into routine primary healthcare, bridging the gap between health and work.
WP3.2 – Primary Care’s Role in Equitable RTW Processes
WP Leaders: Emma Brulin and Lisa Holmlund
Goal:
Strengthen equity and coordination in RTW processes for complex cases.
What we will do:
- Analyse RTW practices for individuals with complex health and social needs.
- Study collaboration, professional roles, and assessment practices.
- Identify structural conditions required for equitable processes.
- Conduct realist evaluations to inform scalable system-level solutions.
Impact: Ensures that RTW processes are inclusive and that no groups are systematically left behind.
WP4 – Policy, Systems and Coordination
WP Leader: Theo Bodin
Goal:
Identify structural gaps in the RTW system and improve coordination between key actors.
What we will do:
- Analyse interactions between healthcare, employers, occupational health services, and the social insurance system.
- Identify underused supports and compensation mechanisms.
- Develop policy recommendations and practical guidance.
Impact: Creates a more coherent and coordinated RTW system, reducing fragmentation and improving outcomes.
WP5 – Innovation
WP Leader: Christina Björklund
Goal:
Translate evidence from WP1–WP4 into usable and scalable solutions.
What we will do:
- Develop need-driven and user-centred innovations.
- Create digital and organisational tools to support RTW.
- Test, refine, and prepare solutions for large-scale implementation.
Impact: Ensures that research findings lead to real-world impact, making RTW processes more effective and accessible.
WP6 – Education and Knowledge Translation
WP Leaders: Jenny Selander and Emma Brulin
Goal:
Establish a national and international competence hub for RTW.
What we will do:
- Provide education for healthcare professionals, occupational health services, employers, and authorities.
- Develop digital courses, certification programmes, and practice-oriented learning formats.
- Support long-term implementation of evidence-based practices.
Impact: Builds sustainable capacity and ensures long-term societal impact through accessible, high-quality education.
