Single versus double-unit transfusion: Safety and efficacy for patients with hematologic malignancies.

ABSTRACT: OBJECTIVES:Although hemoglobin thresholds for red blood cell (RBC) transfusion have decreased, double-unit RBC transfusion practices persist. We studied the effects switching from predominantly double-unit to single-unit RBC transfusions had on utilization and clinical outcomes for malignant hematology patients. METHODS:Retrospective chart review compared malignant hematology patients before and after implementing single-unit RBC transfusion policy. Hemoglobin threshold was 8.0 g/dL for both groups. RBC utilization metrics included number of RBC units transfused, RBC units transfused per admission, and number of transfusion episodes. Clinical outcomes included length of stay, 30-day mortality, and outpatient RBC transfusion 30-days post-discharge. RESULTS:Baseline hemoglobin was similar in both groups. The single-unit group was transfused with fewer RBC units per admission (5.1 vs 4.5, P = 0.01) than the double-unit group, but had more transfusion episodes per admission (4.1 vs 2.7, P < 0.001). After implementing single-unit policy, a 29% reduction in RBC utilization was observed. Mean hemoglobin at discharge was lower in the single-unit group (8.9 vs 9.5 g/dL, P = 0.005). No significant differences in length of stay or 30-day mortality were observed. CONCLUSION:Transfusing malignant hematology patients with single RBC units is safe and efficacious. Electronic provider order systems facilitating RBC transfusion requests provide excellent adherence to transfusion policy.

Project description:BACKGROUND:The objective of this study was to evaluate the short-term and long-term outcomes of adult patients with hematologic malignancies who received chemotherapy in the intensive care unit (ICU). METHODS:This was a retrospective, single-center study comparing the outcomes of patients with hematologic malignancies who received chemotherapy in the ICU with a matched cohort of ICU patients who did not receive chemotherapy. Conditional logistic regression and shared-frailty Cox regression were used to assess short-term (ICU and hospital) mortality and death by 12 months after hospital discharge, respectively. RESULTS:One hundred eighty-one patients with hematologic malignancies received chemotherapy in the ICU. The ICU and hospital mortality rates were 25% and 42% for chemotherapy patients and 22% and 33% for non-chemotherapy patients, respectively. Higher severity of illness scores on ICU admission were significantly associated with higher ICU mortality (odds ratio, 1.07; P < .001) and hospital mortality (odds ratio, 1.05; P ≤ .001). Six-month and 12-month survival estimates posthospital discharge were 58% and 50%, respectively. Compared with the matched cohort of patients who did not receive chemotherapy, those who did receive chemotherapy had a significantly longer length of stay in the ICU (median, 6 vs 3 days; P < .001) and in the hospital (median, 22 vs 14 days; P = .024). In multivariable analysis, the patients who received chemotherapy in the ICU had a trend toward a higher risk of dying by 12 months (hazard ratio, 1.45; P = .08). CONCLUSIONS:Short-term mortality was similar among patients with hematologic malignancies who did and did not receive chemotherapy in the ICU, although patients who received chemotherapy had increased resource utilization. These results may inform ICU triage and goals-of-care discussions with patients and their families regarding outcomes after receiving chemotherapy in the ICU.

Project description:BackgroundUmbilical-cord blood has been used as the source of hematopoietic stem cells in an estimated 30,000 transplants. The limited number of hematopoietic cells in a single cord-blood unit prevents its use in recipients with larger body mass and results in delayed hematopoietic recovery and higher mortality. Therefore, we hypothesized that the greater numbers of hematopoietic cells in two units of cord blood would be associated with improved outcomes after transplantation.MethodsBetween December 1, 2006, and February 24, 2012, a total of 224 patients 1 to 21 years of age with hematologic cancer were randomly assigned to undergo double-unit (111 patients) or single-unit (113 patients) cord-blood transplantation after a uniform myeloablative conditioning regimen and immunoprophylaxis for graft-versus-host disease (GVHD). The primary end point was 1-year overall survival.ResultsTreatment groups were matched for age, sex, self-reported race (white vs. nonwhite), performance status, degree of donor-recipient HLA matching, and disease type and status at transplantation. The 1-year overall survival rate was 65% (95% confidence interval [CI], 56 to 74) and 73% (95% CI, 63 to 80) among recipients of double and single cord-blood units, respectively (P=0.17). Similar outcomes in the two groups were also observed with respect to the rates of disease-free survival, neutrophil recovery, transplantation-related death, relapse, infections, immunologic reconstitution, and grade II-IV acute GVHD. However, improved platelet recovery and lower incidences of grade III and IV acute and extensive chronic GVHD were observed among recipients of a single cord-blood unit.ConclusionsWe found that among children and adolescents with hematologic cancer, survival rates were similar after single-unit and double-unit cord-blood transplantation; however, a single-unit cord-blood transplant was associated with better platelet recovery and a lower risk of GVHD.

Project description:RationalePlacement of an indwelling pleural catheter is an established modality for symptom relief and pleurodesis in the treatment of malignant pleural effusion. Concerns remain regarding possible infectious complications, risk of hemorrhage, and the rate of pleurodesis with the use of pleural catheters in the treatment of hematologic malignancies.ObjectivesThe goals of our study were: (1) to evaluate the safety and cumulative incidence of pleurodesis with indwelling pleural catheters for patients with hematologic malignancies, and (2) to evaluate overall survival of this cohort of patients with pleural effusions.MethodsWe performed a retrospective review of 172 patients with a hematologic malignancy who underwent placement of an indwelling pleural catheter between September 1997 and August 2011 at the University of Texas MD Anderson Cancer Center in Houston, Texas. A competing risk model analysis was used for complications and pleurodesis. Analysis was based on each patient's first intrapleural catheter.ResultsThere were 172 patients with lymphoma (58%), acute (16%) or chronic leukemia (16%), or multiple myeloma (10%). The effusions were characterized as malignant (85.5%), infectious (4.1%), volume overload (4.7%), or therapy-related (4.7%). Chylothorax was found in 20.1%. Pleural biopsies were obtained from 13 patients. The cumulative incidence of all complications was 13.6%, and the cumulative incidence of all significant catheter-related complications was 9.5%. The incidence of empyema was 2.9%, and major bleeding (requiring transfusion or intervention) was 1.7%. Thirty-day procedure-associated mortality was 0.6%. The cumulative incidence of pleurodesis at 180 days was 50%, with a median time to pleurodesis of 81 days for the entire cohort.ConclusionsIndwelling pleural catheters appear to be safe for patients with hematologic malignancies. Complications and the cumulative incidence of pleurodesis are comparable to those reported for patients with solid organ malignancies.
