Clinical Trial Summary

Hematopoietic stem cell transplantation (HCT) has the potential to cure a variety of malignant and non-malignant diseases. However, it is associated with significant morbidity, and treatment-related mortality. This is due in large part to the prolonged pancytopenia and immunosuppression associated with the preparatory regimen of chemotherapy and/or radiation and the wait until engraftment of the transplanted hematopoietic stem cells. During this vulnerable period, infectious complications are common. Historically HCT patients were kept in protected environments to safeguard their health during the pancytopenic phase; despite these measures, infectious complications and graft versus host disease (GVHD) remained common and lead to significant morbidity and mortality after HCT. Currently patients are still closely watched in the inpatient or day hospital environment, though recent practices allow patients more freedom. This study randomizes eligible patients to receive post-transplant care at home vs. in the hospital or clinic, per standard of care. The primary objective is to compare the incidence of grade II-IV acute GVHD at 6 months in patients receiving patient-centered medical home (PCMH) vs standard care.


Description:

The patient-centered medical home (PCMH) is an exciting strategy that has the potential to revolutionize hematopoietic stem cell transplantation (HCT). Traditionally, home care has been used for palliative care in end-stage cancer patients and in geriatrics. More recently the PCMH has gained increasing adoption for both primary care and care of medically complex patients. The core of the PCMH lies in the interaction between the healthcare team, the patient's family and support, and above all, the patient. These interactions can be enhanced through health information technologies such as the electronic health record (EHR) and videoconferencing via iPads. In addition, collection of patient reported outcomes (PRO) will allow feedback and adjustments. This integration is especially important when considering the multiple complicated needs of the HCT patient: navigating a Byzantine healthcare system that often requires input and coordination from multiple specialists including transplanters, hematologists, infectious disease physicians, gastroenterologists, psychiatrists, nutritionists, pharmacists, social workers, financial coordinators, etc.; managing medication regimens to prevent infections, GVHD, and other complications (not to mention avoiding drug and food interactions); adjusting to multiple side effects including fatigue, weakness, anorexia, nausea, vomiting, diarrhea, rashes, pain, anxiety, stress, organ failure, etc.; the sheer amount of time required for healthcare visits, lab draws, waiting for results, infusions, transfusions, etc.; physical and psychosocial struggles of living with a life-threatening disease; and the burdens of a treatment that often seems as debilitating as the disease. The PCMH provides patient-centered, comprehensive, accessible, and coordinated care and a systems-based approach to quality and safety: these attributes are essential to the successful care of the complicated HCT patient. this approach has the potential to lower overall costs while preserving or increasing the quality of care.

Intervention

Other:
Patient-Centered Medical Home (PCMH)
Subjects will receive their conditioning chemotherapy +/- radiation and stem cells in the hospital or day hospital, after which they will receive care during the neutropenic/recovery period at home. Advanced Practice Providers (APP) will travel to subjects' homes in the morning, where they will perform the same daily assessment as standard care. They will draw labs and bring them back to the hospital for processing. When results are available, a second home visit is made to deliver necessary interventions. Subjects will have internet access through cellular-networked iPads and have daily videoconferences with their physicians. Daily follow up at home will continue until discharge as per above criteria.
Standard Care
Subjects will receive their conditioning chemotherapy +/- radiation and stem cells in the hospital or day hospital, after which they will receive care during the neutropenic/recovery period inpatient or outpatient. Advanced practice providers (APPs) will perform histories and physical exams. Nurses will collect labs and inpatient rounds occur twice daily, or for outpatients receiving care through our outpatient clinics, a healthcare provider typically sees them daily for the first month following transplant or discharge from the day hospital.

Outcome

Type Measure Description Time frame Safety issue
Other Comparison of Gut Microbiota Shannon diversity index will be compared using unpaired two-sided Student's t tests with a more stringent cut-off of 0.0125 given multiple comparisons, by the Bonferroni correction for 4 time periods of independent comparisons. Comparisons of bacterial populations will be made by using the Adonis non-parametric method from within the Qiime package using UnifFrac distance matrices from the populations being compared. P values will be calculated with a= 0.05. Metastatistics will be used for further statistical analyses of population structure, membership, and diversity with metadata such as time from transplant and dietary measurements such as caloric intake. Changes in specific bacterial families of interest will be compared using a two-sided Student's t test, with normality confirmed by D'Agostino and Pearson omnibus test with p=0.05. All other comparisons will be done using two-sided Mann-Whitney tests. 6 months
Primary Acute Graft Versus Host Disease (aGVHD) The primary endpoint is the incidence (number of events) of grade II-IV acute GVHD at 6 months. GVHD will be evaluated daily by advanced practice providers (APPs) according to standard criteria. The investigators will compare GVHD incidence rates between treatment arms using survival type regression modeling that takes competing risks into account. They will examine cause-specific Cox proportional hazards models as well as the proportional subdistribution hazard regression model developed by Fine and Gray. While the primary treatment comparison will be unadjusted, adjustment for covariates to explore the impact of various risk factors will also be performed. 6 months
Secondary Rate of Infection Rates of bacterial, fungal, and viral infections as well as overall infections at one year. 1 year
Secondary Disease Free Survival (DFS) Disease free survival at one year. 1 year
Secondary Overall Survival Overall survival at one year. 1 year
