<h3>Background</h3> The World Health Organization has declared that ‘climate change is the greatest threat to global health in the 21st century’.<sup>1</sup> Health systems, including palliative and hospice care, have a responsibility to mitigate their environmental footprint. Truly holistic care should encompass physical, psychosocial, spiritual, and sustainable dimensions of wellbeing—the latter increasingly recognised as a core element of healthcare quality.<sup>2</sup> A potential overlooked source of waste in palliative settings is the frequent replacement of 9V alkaline batteries used in syringe drivers. The production of these batteries is resource- and energy-intensive, involving the extraction of zinc, manganese, and steel, while disposal or recycling carries notable environmental burdens.<sup>3</sup> An audit of current practice in our hospice identified an average battery replacement threshold of 40% remaining charge (range 18–50%), with no formal policy to guide replacement threshold. <h3>Aim</h3> To reduce environmental impact and waste from syringe driver use by lowering the battery replacement threshold from 40% to 15%, thereby decreasing annual battery consumption. <h3>Methods</h3> Syringe driver charts were audited to assess replacement levels and battery drainage rates. Extrapolating the data allowed for estimation of battery usage and lifespan (approximately 20% drainage per 24 hours). <h3>Results</h3> Modelling predicts each syringe driver would use approximately 37 fewer batteries per year under a 15% threshold compared with 40%. For a fleet of 20 devices, this represents 740 fewer batteries annually: reducing cost, landfill waste, potential heavy metal pollution, and carbon emissions from manufacture and transport. <h3>Conclusions</h3> Lowering the battery replacement threshold for syringe drivers is a low-cost, low-risk intervention with measurable environmental benefits. Its adoption within hospice care demonstrates how sustainable practice can be embedded into clinical operations, supporting healthcare’s duty to reduce its environmental footprint. <h3>References</h3> World Health Organization (2023).
