They do their utmost: promise and limits of palliative care in two refugee camps in Rwanda, a qualitative study.

After often gruelling journeys, some refugees arrive at secure locations with severe injury or illness. Others find themselves shortly thereafter facing a life-limiting health condition. Palliative care has been the focus of recent research, and of academic and aid sector dialogue. In this study, we ask: What are experiences and needs of patients and care providers? What opportunities and obstacles exist to enhance or introduce means of reducing suffering for patients facing serious illness and injury in crisis settings? We present findings of a qualitative sub-study within a larger programme of research exploring moral and practical dimensions of palliative care in humanitarian crisis contexts. This paper presents vignettes about palliative care from refugees and care providers in two refugee camps in Rwanda, and is among the first to provide empirical evidence on first-hand experiences of individuals who have fled protracted conflict and face dying far from home. Along with narratives of their experiences, participants provided a range of recommendations from small (micro) interventions that are low cost, but high impact, through to larger (macro) changes at the systems and societal levels of benefit to policy developers and decision-makers.

Aid when 'there is nothing left to offer': Experiences of palliative care and palliative care needs in humanitarian crises.

Access to palliative care, and more specifically the alleviation of avoidable physical and psychosocial suffering is increasingly recognized as a necessary component of humanitarian response. Palliative approaches to care can meet the needs of patients for whom curative treatment may not be the aim, not just at the very end of life but alleviation of suffering more broadly. In the past several years many organizations and sectoral initiatives have taken steps to develop guidance and policies to support integration of palliative care. However, it is still regarded by many as unfeasible or aspirational in crisis contexts; particularly where care for persons with life threatening conditions or injuries is logistically, legally, and ethically challenging. This article presents a synthesis of findings from five qualitative sub-studies within a research program on palliative care provision in humanitarian crises that sought to better understand the ethical and practical dimensions of humanitarian organizations integrating palliative care into emergency responses. Our multi-disciplinary, multi-national team held 98 in-depth semi-structured interviews with people with experiences in natural disasters, refugee camps in Rwanda and Jordan, and in Ebola Treatment Centers in Guinea. Participants included patients, family members, health care workers, and other staff of humanitarian agencies. We identified four themes from descriptions of the struggles and successes of applying palliative care in humanitarian settings: justification and integration of palliative care into humanitarian response, contextualizing palliative care approaches to crisis settings, the importance of being attentive to the 'situatedness of dying', and the need for retaining a holistic approach to care. We discuss these findings in relation to the ideals embraced in palliative care and corresponding humanitarian values, concluding that palliative care in humanitarian response is essential for responding to avoidable pain and suffering in humanitarian settings.

Morbidity and mortality in patients managed with high compared with low blood pressure targets during on-pump cardiac surgery: a systematic review and meta-analysis of randomized controlled trials.

PURPOSE: Many believe that blood pressure management during cardiac surgery is associated with postoperative outcomes. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to determine the impact of high compared with low intraoperative blood pressure targets on postoperative morbidity and mortality in adults undergoing cardiac surgery on cardiopulmonary bypass (CPB). Our primary objective was to inform the design of a future large RCT. SOURCE: We searched MEDLINE, EMBASE, Web of Science, CINAHL, and CENTRAL for RCTs comparing high with low intraoperative blood pressure targets in adult patients undergoing any cardiac surgical procedure on CPB. We screened reference lists, grey literature, and conference proceedings. PRINCIPAL FINDINGS: We included eight RCTs (N =1,116 participants); all examined the effect of blood pressure management only during the CPB. Trial definitions of high compared with low blood pressure varied and, in some, there was a discrepancy between the target and achieved mean arterial pressure. We observed no difference in delirium, cognitive decline, stroke, acute kidney injury, or mortality between high and low blood pressure targets (very-low to low quality evidence). Higher blood pressure targets may have increased the risk of requiring a blood transfusion (three trials; n = 456 participants; relative risk, 1.4; 95% confidence interval, 1.1 to 1.9; P = 0.01; moderate quality evidence) but this finding was based on a small number of trials. CONCLUSION: Individual trial definitions of high and low blood pressure targets varied, limiting inferences. The effect of high (compared with low) blood pressure targets on other morbidity and mortality after cardiac surgery remains unclear because of limitations with the body of existing evidence. Research to determine the optimal management of blood pressure during cardiac surgery is required. STUDY REGISTRATION: PROSPERO (CRD42020177376); registered: 5 July 2020.

RéSUMé: OBJECTIF: Pour beaucoup, la prise en charge de la pression artérielle pendant la chirurgie cardiaque serait associée aux issues postopératoires. Nous avons réalisé une revue systématique et une méta-analyse d'études randomisées contrôlées (ERC) afin de déterminer l'impact de cibles peropératoires de pression artérielle élevées par rapport à des cibles basses sur la morbidité et la mortalité postopératoires d'adultes bénéficiant d'une chirurgie cardiaque sous circulation extracorporelle (CEC). Notre objectif principal était d'orienter la conception d'une future ERC d'envergure. SOURCES: Nous avons analysé les bases de données MEDLINE, EMBASE, Web of Science, CINAHL et CENTRAL afin d'en tirer les ERC comparant des cibles de pression artérielle peropératoire élevées à des cibles basses chez des patients adultes bénéficiant d'une intervention chirurgicale cardiaque sous CEC. Nous avons passé au crible les listes de références, la littérature grise et les travaux de congrès. CONSTATATIONS PRINCIPALES: Nous avons inclus huit ERC (N = 1116 participants); toutes les études ont examiné l'effet de la prise en charge de la pression artérielle uniquement pendant la CEC. Les définitions d'une pression artérielle élevée ou basse variaient d'une étude à l'autre et, dans certains cas, un écart a été noté entre la pression artérielle cible et la pression artérielle moyenne atteinte. Nous n'avons observé aucune différence dans les taux de delirium, de déclin cognitif, d'accident vasculaire cérébral, d'insuffisance rénale aiguë ou de mortalité entre les cibles de pression artérielle élevée et basse (données probantes de qualité très faible à faible). Des cibles de pression artérielle plus élevées pourraient avoir augmenté le risque de transfusion sanguine (trois études; n = 456 participants; risque relatif, 1,4; intervalle de confiance à 95 %, 1,1 à 1,9; P = 0,01; données probantes de qualité modérée), mais ce résultat se fondait sur un petit nombre d'études. CONCLUSION: Les définitions individuelles des cibles d'hypertension et d'hypotension artérielle variaient, ce qui a limité les inférences. L'effet de cibles de pression artérielle élevée (par rapport à une pression artérielle basse) sur d'autres mesures de la morbidité et de la mortalité après une chirurgie cardiaque demeure incertain en raison des limites de l'ensemble des données probantes existantes. Des recherches visant à déterminer la prise en charge optimale de la pression artérielle pendant la chirurgie cardiaque sont nécessaires.

Optimal medical therapy after coronary artery bypass grafting: a primer for surgeons.

PURPOSE OF REVIEW: After coronary artery bypass grafting (CABG), patients remain at increased risk of cardiovascular events and death. Cardiac surgeons have the opportunity to reduce this risk by optimizing post-CABG patients' medical therapy. RECENT FINDINGS: Recent developments in lipid-lowering, diabetes management, antithrombotic therapy, and anti-inflammatory therapy can significantly improve prognosis in patients with chronic coronary artery disease. PCSK-9 inhibitors should be used in patients with elevated LDL cholesterol despite maximally tolerated statin therapy. Icosapent ethyl should be considered in patients with elevated triglycerides despite maximally tolerated statin therapy. Long-acting GLP-1 receptor agonists or SLGT-2 inhibitors should be used in all post-CABG patients with type 2 diabetes. Intensified antithrombotic therapy with DAPT or DPI reduces MACE (and DPI reduces mortality) in patients with high atherosclerotic burden. Colchicine has not yet been incorporated into guidelines on OMT for stable CAD but it is reasonable to consider using it in high-risk patients. SUMMARY: We review the foundations of optimal medical therapy after CABG, and summarize recent advances with a focus on practical application for the busy cardiac surgeon.
