PolyU HEROCARE revolutionises paediatric radiotherapy with immersive technology, achieving an 88% reduction in anaesthesia use

Children undergoing radiotherapy often face intense fear and anxiety due to the intimidating environment of large machines, loud machine noise, and being alone in the treatment room. To combat this, a multidisciplinary team from The Hong Kong Polytechnic University (PolyU), comprising experts from the Department of Health Technology and Informatics and the Industrial Centre, has leveraged cutting-edge mixed reality technology at the Hybrid Immersive Virtual Environment (HiVE) to create a more reassuring setting for children during radiotherapy preparation.

The HEROCARE (Holistic Empowerment in Radiation Oncology) programme at PolyU utilises HiVE technology to enhance the physical and emotional well-being of paediatric cancer patients and their carers throughout the course of radiotherapy. Supported by the Lee Hysan Foundation and the Research Grants Council’s Research Matching Grant Scheme, this four-year initiative is backed by over HK$4 million in funding.

Each year, 40–60 paediatric patients in Hong Kong require radiotherapy. The HEROCARE programme seeks to include all eligible children aged 3–17 in its comprehensive workshops, which feature personalised preparatory sessions, treatment rehearsals, and on-site hospital support. Led by Dr Shara Lee, Associate Professor; Dr Helen Law, Associate Professor; and Dr Vincent Leung, Associate Professor of Practice from the Department of Health Technology and Informatics, alongside engineers Ir Dr Kevin Wong, Trista Leung, and Astin Wu from the Industrial Centre, this multidisciplinary effort aims to significantly reduce the reliance on anaesthesia in paediatric radiotherapy.

To date, the programme has achieved a 70% reduction in daily treatment times, along with notable improvements in participants' physical and emotional health. By utilising an experiential learning model, the programme also enhances the compassionate learning of future radiographers, providing them with hands-on experience and deepening their understanding of patient-centred care. The initiative is advocating for its adoption as a standard service model by the Hospital Authority in Hong Kong.

Beyond improving the radiotherapy experience for children, HEROCARE is working to validate its effectiveness, expand its benefits to a wider patient population, and establish itself as the standard approach for paediatric radiotherapy in Hong Kong. Initial research has shown that 88% of participating children have completed radiotherapy without anaesthesia, securing extensive support from hospitals, experts, and universities across Hong Kong.

The HEROCARE programme was launched during the challenging conditions of the COVID-19 pandemic when carers and social workers were restricted from hospital areas. By leveraging PolyU’s research facilities and expertise, the team developed this innovative programme to support paediatric patients' clinical preparation outside of hospitals. The programme also addresses the trauma and adverse effects associated with repeated anaesthesia in paediatric radiotherapy.

HEROCARE is more than just a transformative initiative for paediatric cancer care—it is an exemplary model of integrating experiential compassionate learning with clinical service, fostering a sustainable support system that benefits patients, carers, and future healthcare professionals.
