A Systematic Review of Stakeholder Perspectives of Dignity and Assisted Dying.

INTRODUCTION

The debate on assisted dying and its components, euthanasia and physician-assisted suicide has evolved with the emergence of the right to dignity and the wish to hasten death (WTHD). Whilst shaped by local legal and sociocultural considerations, appreciation of how patients, healthcare professionals and lawmakers relate notions of dignity to self-concepts of personhood and the desire for assisted dying will better inform and direct support of patients.

METHODS

Guided by the Systematic Evidence Based Approach, a systematic scoping review (SSR in SEBA) on perspectives of dignity, WTHD and personhood featured in PubMed, Embase, PsycINFO, Cochrane Database of Systematic Reviews, CINAHL, Scopus databases and four key Palliative Care journals was conducted. The review hinged on the following questions: "what is the relationship between dignity and the wish to hasten death (WTHD) in the assisted dying debate?", "how is dignity conceptualised by patients with WTHD?" and "what are prevailing perspectives on the role of assisted dying in maintaining a dying patient's dignity?"

RESULTS

6947 abstracts were identified, 663 full text articles reviewed, and 88 articles included. The four domains identified include 1) concepts of dignity through the lens of the Ring Theory of Personhood (RToP) including their various definitions and descriptions; 2) the relationship between dignity, WTHD and assisted dying with loss of dignity and autonomy foregrounded; 3) stakeholder perspectives for and against assisted dying including those of patient, healthcare provider and lawmaker; and 4) other dignity-conserving measures as alternatives to assisted dying.

CONCLUSION

Concepts of dignity constantly evolve throughout the patient's end of life journey. Understanding when and how these concepts of personhood change and trigger the fear of a loss of dignity or intractable suffering could direct timely, individualised and appropriate person-centred dignity conserving measures. We believe an RToP-based tool could fulfil this role and further study into the design of this tool is planned.
