A novel Iowa-Mayo validated composite risk assessment tool for allogeneic stem cell transplantation survival outcome prediction.

Allogeneic hematopoietic stem cell transplantation (HSCT) is a curative option for many hematologic conditions and is associated with considerable morbidity and mortality. Therefore, prognostic tools are essential to navigate the complex patient, disease, donor, and transplant characteristics that differentially influence outcomes. We developed a novel, comprehensive composite prognostic tool. Using a lasso-penalized Cox regression model (n = 273), performance status, HCT-CI, refined disease-risk index (rDRI), donor and recipient CMV status, and donor age were identified as predictors of disease-free survival (DFS). The results for overall survival (OS) were similar except for recipient CMV status not being included in the model. Models were validated in an external dataset (n = 378) and resulted in a c-statistic of 0.61 and 0.62 for DFS and OS, respectively. Importantly, this tool incorporates donor age as a variable, which has an important role in HSCT outcomes. This needs to be further studied in prospective models.

Benefits of collaborative patient care rounds in the intensive care unit.

BACKGROUND: Improving care of critically ill patients requires using an interprofessional care model and care standardisation. OBJECTIVES: Determine whether collaborative patient care rounds in the intensive care unit increases practice consistency with respect to common considerations such as delirium prevention, device use, and indicated prophylaxis, among others. Secondary objective to assess whether collaborative interprofessional format improved nursing perceptions of collaboration. METHODS: Single centre, pre- and post- intervention design. collaborative patient care rounding format implemented in three intensive care units in an academic tertiary care centre. format consisted of scripted nursing presentation, provider checklist of additional practice considerations, and daily priority goals documentation. measurements included nursing participation, consideration of selected practice items, daily goal verbalisation, and nursing perception of collaboration. RESULTS: Pre- and post-intervention measurements indicate gains in consideration of eight of thirteen bundle items (p < 0.05), with the greatest gains seen in nurse-presented items. Increases were observed in verbalisation of daily goals (59.8% versus 89.1%, p < 0.0001), nurse participation (83.9% versus 91.8%, p = 0.056), and nurse collaboration ratings (p < 0.0001). CONCLUSION: This study describes implementation of collaborative patient care rounds with corresponding increases in consideration of selected practice items, verbalisation of daily goals, and perceptions of collaboration.

Extracorporeal Photopheresis Improves Survival in Hematopoietic Cell Transplant Patients with Bronchiolitis Obliterans Syndrome without Significantly Impacting Measured Pulmonary Functions.

We carried out the first matched retrospective cohort study aimed at studying the safety and efficacy of extracorporeal photopheresis (ECP) for bronchiolitis obliterans syndrome (BOS) after allogeneic hematopoietic cell transplantation (HCT). Medical records of 1325 consecutive adult patients who underwent HCT between 2005 and 2015 were reviewed. Seventy-four patients (median age, 51 years) with a diagnosis of BOS were included in the study. After propensity-score matching for BOS severity, 26 patients who underwent ≥3 months of ECP were matched to 26 non-ECP-treated patients, who were assigned an index date corresponding to the ECP start date for their matched pairs. The rate of decline in FEV1 percentage predicted (FEV1PP) decreased after ECP initiation (and after index date in the non-ECP group), with no significant difference between the 2 groups (P = .33). On a multivariable analysis that included baseline transplant and pulmonary function test variables, matched related donor HCT (HR, .1; 95% CI, .03 to .5; P = .002), ECP (HR, .1; 95% CI, .01 to .3; P = .001), and slower rate of decline in FEV1PP before the ECP/index date (HR, .7; 95% CI, .6 to .8; P = .001) were associated with a better overall survival. At last follow-up, non-ECP-treated patients were more likely to be on >5 mg daily dose of prednisone (54% versus 23%; P = .04) and had a greater decline in their Karnofsky performance score (mean difference, -9.5 versus -1.6; P = .06) compared with ECP-treated-patients. In conclusion, compared with other BOS-directed therapies, ECP was found to improve survival in HCT patients with BOS, without significantly impacting measured pulmonary functions. These findings need prospective validation in a larger patient cohort.
