Rural healthcare practitioners face persistent challenges such as limited staffing, geographic isolation, and broad scopes of responsibility. These conditions require constant adaptation to ensure care delivery. This study introduces the concept of plasticity, adapted from sociobiology; to examine how rural healthcare teams collectively navigate scarcity through flexible role and task shifting. Drawing on constructivist grounded theory, we conducted 19 interviews with nurses and physicians in emergency departments in two rural communities in Ontario, Canada, to explore how plasticity functions in rural healthcare teams. The analysis identified two variations of plasticity: acute (short-term, high-stakes task switching or role expansion) and chronic (long-term role expansion), alongside four interrelated dimensions that characterize this phenomenon in rural settings. While acute plasticity was often empowering, chronic plasticity, exacerbated by the COVID-19 pandemic, contributed to cumulative stress, burnout, and professional demoralization. Our analysis illustrates that plasticity is both a strength and vulnerability in rural healthcare work, sustained through informal learning and relational responsibility to community, yet largely unsupported by formal institutional structures.

Ethics committee of the University of Western University gave ethical approval for this study.

I confirm that all necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived, and that any patient/participant/sample identifiers included were not known to anyone (e.g., hospital staff, patients or participants themselves) outside the research group so cannot be used to identify individuals.

Yes

I understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov. I confirm that any such study reported in the manuscript has been registered and the trial registration ID is provided (note: if posting a prospective study registered retrospectively, please provide a statement in the trial ID field explaining why the study was not registered in advance).

Yes

I have followed all appropriate research reporting guidelines, such as any relevant EQUATOR Network research reporting checklist(s) and other pertinent material, if applicable.

Yes

The data that support the findings of this study are not publicly available due to the potential risk of participant identification within two rural communities.
