ABSTRACT
INTRODUCTION:
Inhalers are commonly used in the management of respiratory diseases. The propellants used in pressurised metered dose inhalers (pMDIs) are potent greenhouse gases and carry a substantial global warming potential. Dry powder inhalers (DPIs) are propellant-free alternatives that have fewer consequences on the environment, while being equally effective. In this study, we assessed patients' and clinicians' attitudes towards choosing inhalers that have a lesser environmental impact.METHODS:
Surveys of patients and practitioners were undertaken in primary and secondary care settings in Dunedin and Invercargill. Fifty-three patient and 16 practitioner responses were obtained.RESULTS:
Sixty-four percent of patients were using pMDIs, while 53% were using DPIs. Sixty-nine percent of patients believed that the environment is an important consideration when switching inhalers. Sixty-three percent of practitioners were aware of the global warming potential of inhalers. Despite this, 56% of practitioners predominantly prescribe or recommend pMDIs. The 44% of practitioners who mostly prescribe DPIs were more comfortable doing so based on environmental impact alone.CONCLUSION:
Most respondents believe global warming is an important issue and would consider changing their inhaler to a more environmentally friendly type. Many people were not aware that pressurised metered dose inhalers have a substantial carbon footprint. Greater awareness of their environmental impacts may encourage the use of inhalers with lower global warming potential.
