Development of a Core Outcome Set for the research and assessment of inoperable malignant bowel obstruction

Palliative surgery: state of the science and future directions

Palliative surgical procedures are operations that aim to alleviate symptoms in a patient with serious, life-limiting illness. They are common, particularly within the field of surgical oncology. However, few high-quality studies have attempted to measure the durability of improvements in symptoms and quality of life after palliative surgery. Furthermore, many of the studies that do exist are outdated and employ highly inconsistent definitions of palliative surgery. Consequently, the paucity of robust and reliable evidence on the benefits, risks, and trade-offs of palliative surgery hampers clinical decision-making for patients and their surgeons. The evidence for palliative surgery suggests that, with effective communication about goals of care and careful patient selection, palliative surgery can provide symptomatic relief and reduce healthcare burdens for certain seriously ill patients.

Exploring pathways to optimise care in malignant bowel obstruction (EPOC): Protocol for a three-phase critical realist approach to theory-led intervention development for shared decision-making

INTRODUCTION

Malignant bowel obstruction is a distressing complication of cancer, causing pain, nausea and vomiting, and often has a poor prognosis. Severe and rapidly developing symptoms, a lack of robust clinical guidelines and the need for multidisciplinary input make treatment decision-making challenging. Sharing decision-making with people with malignant bowel obstruction and their caregivers can be difficult, and inconsistent communication creates serious deficiencies in care by amplifying patients' distress and uncertainty. Little attention has been paid to the implicit influences on this process-for example, the role of discipline-related norms and the beliefs of decision-makers. This study will explore how these processes work and develop interventions to improve shared decision-making.

METHODS AND ANALYSIS

Exploring Pathways to Optimise Care (EPOC) is a three-phase study set within a critical realist framework: (i) realist review, to develop explanatory theory describing collaborative decision-making in the management of malignant bowel obstruction; (ii) an in-depth interview study using modified grounded theory to explore the active ingredients of this collaboration in practice settings; and (iii) the presentation to stakeholders (practitioners, patients and caregivers) of integrated results from Phase I (theory developed from the literature) and Phase II (theory developed from current practice) as a basis for intervention mapping. We aim to produce recommendations to address the challenges, and to develop a set of tools to (i) aid interaction around shared decision-making and (ii) aid interprofessional interaction around the management of this condition. Registration details: The realist review is registered with PROSPERO (CRD42022308251).
