Nanotechnology and Emerging Risks

Evaluating potential health risks from new technologies and materials, particularly nanomaterials, and developing appropriate risk management frameworks.

Global Collaboration and Impact

The collaboration between WHO Collaborating Centres creates synergies and leverage resources to achieve greater impact in occupational health. The compendium demonstrates several ways in which these centres work together:

Joint Research Initiatives

Multiple centres often collaborate on research projects addressing global occupational health priorities, bringing together diverse expertise and resources. This includes multicenter studies on occupational diseases, methodological development work, and systematic reviews.

Standardization and Harmonization

Through collaborative efforts, the centres work toward the standardization of methods, definitions, and approaches in occupational health practice and research, facilitating global comparisons and knowledge exchange.

Resource and Knowledge Sharing

The network enables sharing of educational materials, best practices, and technical resources among institutions, reducing duplication and enhancing the overall quality and reach of occupational health initiatives.

Regional Support

Centres often provide technical support and expertise to improve occupational health services in their respective regions, adapting global knowledge to local contexts and challenges.

Innovative Approaches in Occupational Health

The compendium highlights several innovative approaches and methods developed by WHO Collaborating Centres to address contemporary occupational health challenges:

Use of Technology in Occupational Health

Digital tools, mobile applications, and telemedicine are increasingly employed to expand access to occupational health services, enhance data collection, and facilitate education and training. Several centres have pioneered the development of mobile health applications for occupational health surveillance and intervention in resource-limited settings.

Integration into Primary Health Care

Innovative models for integrating basic occupational health functions into primary health care systems have been developed and tested, particularly in low-resource settings where specialized occupational health services are scarce.

Participatory Approaches

Worker and employer engagement in occupational health initiatives is emphasized in many programs, recognizing the importance of participatory approaches to sustainable improvements in workplace health.

Total Worker Health

Holistic approaches that integrate occupational safety and health with broader health promotion activities are gaining prominence, addressing the full spectrum of factors affecting worker wellbeing.

Specialized Areas of Expertise

WHO Collaborating Centres in occupational health encompass a wide range of specialized expertise, reflecting the multidisciplinary nature of the field. The compendium identifies several key areas of specialization among the centres:

Occupational Toxicology

Centres specializing in occupational toxicology conduct research on the health effects of workplace chemical exposures, develop analytical methods for exposure assessment, and contribute to setting occupational exposure limits.

Occupational Medicine

These centres focus on clinical aspects of occupational health, including diagnosis, treatment, and rehabilitation of work-related diseases, as well as fitness for work assessments.

Occupational Epidemiology

Epidemiological expertise among centres supports investigation of occupational disease patterns, risk factor identification, and evaluation of intervention effectiveness.

Occupational Hygiene

Specialization in recognition, evaluation, and control of workplace environmental hazards, with development of measurement methods and control strategies.

Occupational Ergonomics

Focus on designing workplaces, tools, and work processes to optimize human well-being and overall system performance, preventing musculoskeletal disorders and other work-related injuries.

Occupational Health Nursing

Centres with expertise in occupational health nursing contribute to training, practice development, and research in this important component of occupational health services.

Challenges and Future Directions

The compendium also identifies key challenges facing occupational health globally and potential directions for future work by WHO Collaborating Centres:

Challenges

• Limited coverage of occupational health services worldwide, particularly in low- and middle-income countries
• Rapid changes in the nature of work creating new occupational health risks
• Adequate protection for vulnerable workers including migrant, disabled, and informal workers
• Insufficient surveillance of occupational diseases and injuries in many countries
• Need for stronger integration of occupational health with broader public health and social protection systems

Future Priorities

• Strengthening the evidence base on effective occupational health interventions
• Improving implementation of existing knowledge and guidelines
• Enhancing global and national surveillance of occupational health indicators
• Continuing development of methodologies for assessing emerging risks
• Strengthening the occupational health workforce through training and capacity development
