Design of circular concepts in eye surgery and kidney care

PhD Project: Creating Circular Hospitals

The healthcare sector is responsible for 7% of the total Dutch ecological footprint. According to the Green Deal 3.0, this footprint must be reduced significantly within the next six years. ESCH-R is an interdisciplinary science project funded by the Dutch Research Council (NWA-OCR) as part of the Dutch Research Agenda to create a more sustainable healthcare sector. The acronym ESCH-R stands for ‘Evidence-based Strategies to create Circular Hospitals: Applying the 10-Rs framework to healthcare’.

Within a consortium of academic institutions, a systemic and transdisciplinary approach will be applied, collaborating throughout the whole hospital ecosystem (from suppliers to hospitals, healthcare professionals, patients, and waste management). Strategies towards circular practices for the most impactful medical consumables used in two clinical departments will be developed. We aim to remove current barriers, adopt newly developed interventions, and facilitate a behavioral change of healthcare professionals towards a circular way of working.

In this PhD-project, two clinical cases will be investigated with the objective of a structural reduction in waste and carbon footprint. All aspects of the relevant consumables, from LCA, design, production, usage, to disposal will be targeted. The two cases are eye surgery and kidney care.

Cataract surgery is the most common surgical procedure nationally and internationally, with approximately 180,000 procedures per year in the Netherlands. It is a highly standardized procedure, using similar instruments and techniques. Infection is the most feared complication and this risk has been a major driver for the increasing use of disposables. Together with experts from DORC, a world-leading company in eye surgery equipment, new circular concepts will be developed.

Kidney care, in particular dialysis, has a disproportionately high ecological footprint within healthcare through greenhouse emissions, natural resources depletion, and waste generation. Dialysis is 18 times more resource-intensive than the general healthcare emissions burden of a typical patient. A typical hemodialysis session uses ~400L of tap water and ~20 kWh per patient and produces several kgs of waste. Thus, there is an urgent need to drastically lower the footprint of dialysis. Work will be conducted on the (co-)development of sustainable technological innovations for dialysis and the implementation of innovative green solutions into the new dialysis unit at UMC Utrecht.

This PhD project is based at the UMC Utrecht, with direct supervision from the departments of Ophthalmology (Dr. R van Leeuwen) and Nephrology (Dr. K Gerritsen). In addition, supervision will be provided by Prof. JC Diehl from the department of Industrial Design and Engineering of TU Delft. The R&D departments of the industrial partners DORC and Medtronic and several SMEs are also closely involved. In the UMC Utrecht, a Living Lab for the operating room and an advanced Dialysis Innovation Lab have been established, in which new ideas can be developed and tested.

You will be a member of the ESCH-R community, a highly motivated group of researchers and students, committed to a more sustainable healthcare.
