To investigate the attitudes of physicians towards addressing environmental sustainability in patient conversations, and to identify barriers and facilitators to doing so.

A qualitative, nation-wide study was conducted using semi-structured online focus groups and interviews. Reflexive thematic analysis was used to analyse transcripts, guided by the Theoretical Domains Framework.

Secondary and tertiary healthcare institutions in the Netherlands.

Participants were medical specialists and residents in obstetrics and gynaecology (OB-GYN physicians) in the Netherlands. Participants were purposefully identified to capture diverse demographics and practice settings.

Physicians’ attitudes towards discussing the environmental impact of healthcare and the health effects of environmental pollution with patients. Themes were identified and categorised using the Theoretical Domains Framework.

The study included 28 OB-GYN physicians working across 23 healthcare institutions in the Netherlands. Six themes were developed: (1) strong sense of urgency to reduce healthcare's environmental impact, (2) knowledge gaps impair communication about environmental impact to patients, (3) prioritisation of individual patient health over environmental concerns in decision-making, (4) perceived lack of patient interest in environmental outcomes, (5) system-level support facilitates discussions about environmental sustainability with patients and (6) limited perceived value in discussing the health effects of environmental pollution and climate change with patients.

OB-GYN physicians are supportive of discussing the environmental impact of healthcare services when clinically appropriate. Addressing knowledge gaps, providing evidence-based guidance and embedding sustainability into clinical guidelines and decision aids may facilitate the integration of environmental sustainability into patient-provider interactions.
