Sustainability for Planetary Health: A Seventh Domain of Quality in Primary Care

Climate change is one of the biggest threats to public health. Sustainability is characterized by using resources wisely in a way that protects finite resources and the environment, and takes into account the needs of our planets’ inhabitants in the future. Sustainability in health care should be considered as a seventh domain of quality, as it can lead to improvement of patient outcomes, and more capacity for health care workers to engage in quality improvement and thereby improve the quality of care. The carbon footprint of primary care is high, mainly due to prescribing medication, but also due to the transport of patients to hospitals and primary care services for interventions requested by family medicine. Other causes are the transport of staff and supplies, consumables and staff involved in laboratory analysis and radiation, medical and non-medical equipment, clinical and non-clinical waste, heating and cooling systems and other activities. Small adjustments in these areas could significantly decrease the carbon footprint of primary care practices. The suggested steps for primary care to achieve a more sustainable practice are fostering research, raising awareness, reducing the burden on primary care, engaging in quality improvement, and leadership and advocacy. Each individual primary care practice has the potential to be a leader and role model for sustainable health care. With the implementation of interventions to reduce carbon footprints, primary care could set an example within the health sector and for patients. This could significantly raise the awareness of the public about the need to take actions for a greener health system.
