Hospital Variation in Intensive Care Resource Utilization and Mortality in Newly Diagnosed Pediatric Leukemia.

ABSTRACT: OBJECTIVES:To evaluate hospital-level variability in resource utilization and mortality in children with new leukemia who require ICU support, and identify factors associated with variation. DESIGN:Retrospective cohort study. SETTING:Children's hospitals contributing to the Pediatric Health Information Systems administrative database from 1999 to 2011. PATIENTS:Inpatients less than 25 years old with newly diagnosed acute lymphocytic leukemia or acute myeloid leukemia requiring ICU support (n = 1,754). INTERVENTIONS, MEASUREMENTS, AND MAIN RESULTS:Evaluated exposures included leukemia type, year of diagnosis, and hospital-wide proportion of patients with public insurance. The main outcome was hospital mortality. Wide variability existed in the ICU resources used across hospitals. Combined acute lymphocytic leukemia and acute myeloid leukemia mortality varied by hospital from 0% (95% CI, 0-14.8%) to 42.9% (95% CI, 17.7-71.1%). A mixed-effects model with a hospital-level random effect suggests significant variation across hospitals in mortality (p = 0.007). When including patient and hospital factors as fixed effects into the model, younger age, acute myeloid leukemia versus acute lymphocytic leukemia diagnosis, leukemia diagnosis prior to 2005, hospital-wide proportion of public insurance patients, and hospital-level proportion of leukemia patients receiving ICU care are significantly associated with mortality. The variation across hospitals remains significant with all patient factors included (p = 0.021) but is no longer significant after adjusting for the hospital-level factors proportion of public insurance and proportion receiving ICU care (p = 0.48). CONCLUSIONS:Wide hospital-level variability in ICU resource utilization and mortality exists in the care of children with leukemia requiring ICU support. Hospital payer mix is associated with some mortality variability. Additional study into how ICU support could be standardized through clinical practice guidelines, impact of payer mix on hospital resources allocation to the ICU, and subsequent impact on patient outcomes is warranted.

Project description:BackgroundAlthough the significant burden of heart failure (HF) is well recognized, the relative contributions of systolic HF versus diastolic HF are less defined.ObjectiveTo explore the differential burden between patients with systolic and diastolic HF in terms of treatment patterns, healthcare resource utilization (HCRU), costs, and mortality risk.MethodsThis retrospective cohort study used administrative claims data from a large US commercial health insurer integrated with mortality data. Patients newly diagnosed with HF between January 1, 2010, and June 30, 2016, were identified and grouped according to systolic HF or diastolic HF diagnosis and were followed up to 4 years after diagnosis. Treatment patterns, HCRU, costs, and mortality were compared between the 2 groups of patients.ResultsOverall, 46,885 patients with systolic HF and 21,854 with diastolic HF were identified and included in the study. Patients with systolic HF had less HCRU than those with diastolic HF during the first year after HF diagnosis, including hospital admissions (70.2% vs 82.4%, respectively; P <.001) and emergency department visits (30.5% vs 39.1%, respectively; P <.001). The average per-patient costs for patients with systolic HF during the 1-year follow-up were higher than for those with diastolic HF ($64,154 vs $59,652, respectively; P <.001), but lower during years 2 through 4 (approximately $23,000-$25,000 annually vs approximately $28,000-$29,000 annually; P <.001). Patients with diastolic HF had a higher adjusted hospitalization risk (odds ratio, 1.62; 95% confidence interval [CI], 1.55-1.69), but comparable adjusted costs (exponentiated estimate, 1.01; 95% CI, 0.99-1.02) and slightly lower mortality risk (hazard ratio, 0.96; 95% CI, 0.93-0.99) versus patients with systolic HF. The number of HF-related medication classes received for other diagnoses during the year preceding an HF diagnosis was associated with lower risks for hospitalization, mortality, and lower costs, with a trend in benefits toward patients with systolic HF. Of note, 21.9% of patients with systolic HF and 25% of patients with diastolic HF filled no HF-related prescriptions in the year after diagnosis.ConclusionThis real-world analysis confirms a high disease burden associated with HF and provides insight across the systolic HF and diastolic HF phenotypes. HF-related medication use after diagnosis was suboptimal and underscores a gap in patient care.

Project description:Acute myeloid leukemia (AML) is an aggressive hematological malignancy with a globally poor outcome, especially in patients ineligible for intensive chemotherapy. Until recently, therapeutic options for these patients included low-dose cytarabine (LDAC) or the hypomethylating agents (HMA) azacitidine and decitabine, which have historically provided only short-lived and modest benefits. The oral B-cell lymphoma 2 inhibitor, venetoclax, Venetoclax, an oral B-cell lymphoma 2 (BCL2) inhibitor, is now approved by the USA Food and Drug Administration (FDA) in combination with LDAC or HMA in older AML patients ineligible for intensive chemotherapy. Is now approved by the US Food and Drug Administration for this indication. In the pivotal clinical trials evaluating venetoclax either in combination with LDAC or with HMA, the rates of complete remission (CR) plus CR with incomplete hematological recovery were 54% and 67%, respectively and the median overall survival (OS) was 10.4?months and 17.5?months, respectively, comparing favorably with outcomes in clinical trials evaluating single-agent LDAC or HMA. The most common adverse events with venetoclax combinations are gastrointestinal symptoms, which are primarily low grade and easily manageable, and myelosuppression, which may require delays between cycles, granulocyte colony-stimulating factor (G-CSF) administration, or decreased duration of venetoclax administration per cycle. A bone marrow assessment after the first cycle of treatment is critical to determine dosing and timing of subsequent cycles, as most patients will achieve their best response after one cycle. Appropriate prophylactic measures can reduce the risk of venetoclax-induced tumor lysis syndrome. In this review, we present clinical data from the pivotal trials evaluating venetoclax-based combinations in older patients ineligible for intensive chemotherapy, and provide practical recommendations for the prevention and management of adverse events associated with venetoclax.
