Returning to work in the digital age: why smartphone interventions must go further

Return-to-work (RTW) after long-term absence due to ill health (or other factors) can be fraught with psychological, physical, and organisational challenges which may require continuous management to ensure successful employee reintegration. While digital interventions have emerged to support reintegration, a recent systematic review revealed that few explicitly address RTW needs, despite growing interest in e-mental health. Early online interventions demonstrate promise in improving psychological outcomes, yet face limitations in scalability, personalisation, and integration into workplace systems. Smartphone-based interventions via applications/apps offer a scalable alternative, leveraging ubiquitous technology to deliver support beyond bespoke settings through self-monitoring, continuous learning, and communication tools. However, existing RTW-focused apps remain narrowly tailored to specific conditions, with limited adaptation to individual needs and insufficient evaluation of long-term effectiveness. Future developments must prioritise personalisation, rigorous evaluation in diverse populations, and integration within occupational health and real-world employer systems with organisational support. Addressing these gaps is essential to fully realise the potential of digital solutions in supporting sustainable work reintegration that is respectful and compassionate.
