Shared decision-making with older people on TReatment Escalation planning for Acute deterioration in the emergency Medical Setting: a qualitative study of Clinicians' perspectives (STREAMS-C).

Background: Shared decision-making (SDM) is increasingly expected in healthcare systems prioritising patient autonomy. Treatment escalation plans (TEPs) outline contingency for medical intervention in the event of patient deterioration. This study aimed to understand clinicians' perspectives on SDM in TEP for older patients in the acute medical setting.

Methods: This was a qualitative study following a constructivist approach. Semistructured interviews with vignettes were conducted with 26 consultant and registrar doctors working in emergency medicine, general internal medicine, intensive care medicine and palliative care medicine. Reflexive thematic analysis was performed.

Results: There were three themes: 'An unequal partnership', 'Options without equipoise' and 'Decisions with shared understanding'. Clinicians' expertise in synthesising complex, uncertain clinical information was contrasted with perceived patient unfamiliarity with future health planning and medical intervention. There was a strong sense of morality underpinning decision-making and little equipoise about appropriate TEP decisions. Communication around the TEP was important, and clinicians sought control over the high-stakes decision whilst avoiding conflict and achieving shared understanding.

Conclusions: Clinicians take responsibility for securing a 'good' TEP decision for older patients in the acute medical setting. They synthesise clinical data with implicit ethical reasoning according to their professional predictions of qualitative and quantitative success following medical intervention. SDM is seldom considered a priority for this context. Nonetheless, avoidance of conflict, preserving the clinical relationship and shared understanding with the patient and family are important.
