The long-term detrimental impacts of some pharmaceuticals in the environment have been known for decades, and it is now widely recognised that ambitious legislative and non-legislative measures are required to address this issue.3Organisation for Economic Co-operation and DevelopmentPharmaceutical residues in freshwater: hazards and policy responses. OECD studies on water.

Here, we present a UK case study that illustrates the scale of the problem and demonstrates the need for a cohesive, cross-sectoral systems approach. The UK is a HIC with a large pharmaceutical industry (£36·7 billion turnover in 2019),6Office for Life SciencesBioscience and health technology sector statistics 2019. Office for Life Sciences, London2020Google Scholar a well recognised health-care pharmaceutical market (the UK National Health Service [NHS]), and a diverse water industry comprising both private and public operators working on regional and national scales. Efforts to reduce pharmaceutical pollution derived from UK health care face numerous significant challenges: first, NHS pharmaceutical supply chains are complex and traverse institutional, sectoral, and national boundaries, so defining the environmental impacts of manufacture and supply, and assigning accountability for them, is difficult and disjointed;3Organisation for Economic Co-operation and DevelopmentPharmaceutical residues in freshwater: hazards and policy responses.

We charted the flow of pharmaceutical stock used in UK health care, and the most important factors influencing this flow (figure). Our systems map illustrates the inherent interconnectivity between the health, pharmaceutical, and environmental sectors, and outlines pathways for the integration of policies and frameworks between these. For example, the recent Organisation for Economic Co-operation and Development report on the Management of Pharmaceutical Household Waste8Organisation for Economic Co-operation and DevelopmentManagement of pharmaceutical household waste: limiting environmental impacts of unused or expired medicine. OECD Publishing, Paris2022Google Scholar could be integrated into health-care system strategies, including NHS net-zero and over-prescribing policies.7National Health ServiceNHS website.https://www.england.nhs.uk/Date accessed: July 11, 2022Google Scholar Our map also identifies opportunities to improve cross-sectoral interconnectivity, for example it highlights the scarcity of feedback from the environmental sector into points controlling the flow of pharmaceutical stock through the system (licencing, reimbursement, procurement, and prescription), and the complete absence of feedback relating to international manufacturing pollution. This demonstrates the need for expansion of environmentally responsible initiatives to cover global supply chains, for example in ecopharmacovigilance schemes developed by UK pharmaceutical companies, and in NHS procurement policies. An abundance of potential interventions already exist across the UK health-care-derived pharmaceutical pollution system (appendix). Many of these interventions are aimed at reducing the rate or impact of pharmaceuticals flowing into the environment, for example through greener pharmaceutical design, improved disposal or increased removal from wastewater. From a broader systems perspective, the most effective way to reduce pharmaceutical outflow is likely to be through reducing inflow—ie, by addressing the upstream market forces driving unnecessary pharmaceutical usage. This strategy echoes calls from wider sustainable health-care strategies for greater prioritisation and investment into preventative health care and non-pharmaceutical treatment options. However, like many of the interventions identified (appendix), this is not straightforward, demonstrating the need to consider competing social, health, economic, and environmental factors when designing system-wide intervention strategies. As such, adoption of a systems approach will require dedicated cross-sectoral platforms, with resources and funding to engage and support the major stakeholder groups in jointly discussing, researching, prioritising, and adopting system-wide approaches. The One Health Breakthrough Partnership in Scotland is a successful model of such a multiagency systems approach. With pharmaceutical production predominantly (and increasingly) based in low-income and middle-income countries (LMICs),3Organisation for Economic Co-operation and DevelopmentPharmaceutical residues in freshwater: hazards and policy responses.

These issues are inextricably linked to pharmaceutical pollution derived from health care and pose key barriers to a sustainable global pharmaceutical future.
