Veno-occlusive disease nurse management: development of a dynamic monitoring tool by the GITMO nursing group

Interprofessional Team-based Care of the Hematopoietic Cell Transplantation Patient With Hepatic Veno-occlusive Disease/Sinusoidal Obstruction Syndrome

Hepatic veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS) is a well-recognized complication of allogeneic and autologous hematopoietic cell transplantation (HCT). The diagnosis and treatment of VOD/SOS require the involvement of multiple specialists covering a wide range of expertise. Interprofessional team-based medical care is standard practice for patients undergoing HCT and has been shown to improve patient and provider satisfaction, enhance efficiency, and improve patient outcomes, particularly for patients in complex medical situations like those with VOD/SOS post-HCT. Interdisciplinary team-based models focus on the synthesis and harmonization of knowledge and methods from different disciplines to create an integrative approach to patient care that both maximizes the expertise of each involved specialist and encourages thought beyond each specialist's discipline. Multidisciplinary team members provide additive support and work collaboratively with the core team to provide knowledge from their field. The composition of the interdisciplinary HCT team should center on the needs of the patient and institutional resources and involve the expertise of additional multidisciplinary team members based on clinical needs. This review focuses on interdisciplinary and multidisciplinary team-based care of patients with VOD/SOS post-HCT and provides an example of a collaborative VOD/SOS team that includes transplant physicians, nurses, pharmacists, nutrition/dietary specialists, and intensive care teams.

Veno-occlusive Disease in HSCT Patients: Consensus-based Recommendations for Risk Assessment, Diagnosis, and Management by the GITMO Group

Variation in clinical practice affects veno-occlusive disease management, mainly in patients who undergo allogeneic hematopoietic stem cell transplantation. Disputes about diagnostic criteria, treatment, and prophylaxis, due to the lack of high-quality data, are at the base of this variability. With the aim of limiting inconsistency in clinical care, thus improving both patient outcomes and data collection reliability, the Italian Society of Stem cell transplant (Gruppo Italiano Trapianto Midollo Osseo e Terapia Cellulare) launched a collaborative effort to formulate recommendations based on integration of available evidence and expert's consensus. A systematic method, according to US National Institute of Health guidelines and Italian National System for Guidelines, was used. Twenty-nine recommendations were approved with a strong (20) or weak (9) level of agreement, while 26 were rejected. In particular, the panel pointed out the need to achieve an early diagnosis, encouraging the adoption of European Society for Blood and Marrow Transplantation criteria and the prompt use of ultrasonography. Moreover, our experts strongly recommended in favor of prophylactic use of ursodeoxycholic acid. As soon as a veno-occlusive disease diagnosis is established, treatment with defibrotide should be started for at least 21 days. A number of areas of uncertainty, particularly concerning risk stratification and use of diagnostic tools such as elastography has been identified and discussed.

Diagnosis and Treatment of VOD/SOS After Allogeneic Hematopoietic Stem Cell Transplantation

Hepatic veno-occlusive disease (VOD) or sinusoidal obstruction syndrome (SOS) is a rare complication characterized by hepatomegaly, right-upper quadrant pain, jaundice, and ascites, occurring after high-dose chemotherapy, hematopoietic stem cell transplantation (HSCT) and, less commonly, other conditions. We review pathogenesis, clinical appearance and diagnostic criteria, risk factors, prophylaxis, and treatment of the VOD occurring post-HSCT. The injury of the sinusoidal endothelial cells with loss of wall integrity and sinusoidal obstruction is the basis of development of postsinusoidal portal hypertension responsible for clinical syndrome. Risk factors associated with the onset of VOD and diagnostic tools have been recently updated both in the pediatric and adult settings and here are reported. Treatment includes supportive care, intensive management, and specific drug therapy with defibrotide. Because of its severity, particularly in VOD with associated multiorgan disease, prophylaxis approaches are under investigation. During the last years, decreased mortality associated to VOD/SOS has been reported being it attributable to a better intensive and multidisciplinary approach.

Nursing role in the assessment and care of hepatic sinusoidal obstruction syndrome patients: a consensus paper by the "Gruppo Italiano Trapianto di Midollo Osseo"

PURPOSE

Sinusoidal obstruction syndrome (SOS) is one of the most serious complications post haematopoietic stem cell transplantation (HSCT). The diagnosis of SOS is clinical, but nurses should be involved in the pre-transplant risk assessment period and play a crucial role in the early detection of signs and symptoms during and after hospitalization. The aim of this work is to achieve a consensus on nurses' behaviour in caring for SOS.

METHODS

On behalf of the Italian Group for Bone and Marrow Transplantation (GITMO), a promoter committee was established to put in place a consensus conference approach. A multidisciplinary group of GITMO together with four nurses, three haematology physicians and one patient representative acted as jury, who reviewed the reports and wrote recommendations and suggestions. Recommendations gaining 100% of consensus were considered 'Golden Points of Care'; if a consensus was achieved by ≥ 75% of the jury's members, those recommendations were defined as 'Good Practices'.

RESULTS

Eighteen papers written by nurses as first authors have been identified. Golden Points of Care and Good Practices were worked out for the following topics: nurses' role in general, nurses' role in pre-transplant assessment, pre-transplant risk assessment and risk stratification, baseline monitoring, suspected mild or moderate SOS, suspected severe or very severe SOS and late-onset cases.

CONCLUSION

SOS is relatively rare; therefore, a holistic approach to the patients' needs considering nursing role as essential may result in better care outcomes.
