Effect of Age and Socioeconomic Factors in the Utilization of Chemotherapy in Acute Lymphoblastic Leukemia (ALL): A SEER Database Study of 16,196 Patients.

INTRODUCTION: The use of multiagent chemotherapy in acute lymphoblastic leukemia (ALL) has resulted in improvement in overall survival (OS), albeit to a different extent across various age groups. This large database study aims to assess the disparity in the utilization of chemotherapy in ALL in the real-world setting. MATERIALS AND METHODS: Using the Surveillance, Epidemiology, and End Results database, patients with ALL diagnosis from 2006 to 2016 were identified. Baseline characteristics were compared between the groups who did vs. did not receive chemotherapy using χ2 test. Multivariable logistic regression was used to evaluate the association between various sociodemographic factors and the receipt of chemotherapy in the entire cohort and in different age groups. RESULTS: Out of 16,196 patients, 1258 patients (8%) did not receive chemotherapy. There was a steady increase in the number of patients who did not receive chemotherapy with advancing age: 2.5% (0-18 years), 5.2% (19-40 years), 9.3% (41-65 years), and 36.2% (>65 years). There was an upward trend in the receipt of chemotherapy in patients >65 years over the last decade. In multivariate analysis, the likelihood of receiving chemotherapy decreased with advancing age, single or widowed status, low income and educational status, and lack of insurance. Insurance status was an independent predictor of receipt of chemotherapy across each age category. CONCLUSION: A significant proportion of patients >65 years do not receive chemotherapy in the United States. Age, marital status, income, education, and insurance status contribute to the disparity in utilization of chemotherapy.

Association of insurance types and outcomes in acute promyelocytic leukemia.

Understanding the association between insurance status and survival in an evolving US healthcare system remains a challenge but is essential to address healthcare disparities. We utilized National Cancer Database to evaluate the effects of insurance type on one-month mortality and overall survival (OS) in patients with acute promyelocytic leukemia. Among patients <65 years, one-month mortality was worse for uninsured patients and patients with Medicare compared to patients with private insurance. OS was similar between patients with private insurance and uninsured patients but worse for patients with Medicare and Medicaid/other government insurance. In multivariate analysis, older age and greater comorbidity burden conferred worse OS. For patients ≥65 years, insurance type did not affect one-month mortality and OS. Older age, greater comorbidity burden, and treatment at non-academic centers conferred worse one-month mortality and OS. Our results highlight healthcare disparities based on insurance types for both younger and older patients.

Impact of Insurance on Overall Survival in Acute Lymphoblastic Leukemia: A SEER Database Study.

INTRODUCTION: Insurance status at diagnosis remains an important barrier to health care access and adherence to treatment. Here, we aim to assess the impact of insurance status, and age on overall survival (OS) in patients with acute lymphoblastic leukemia (ALL). MATERIALS AND METHODS: Using the Surveillance, Epidemiology, and End Results database, we identified all patients younger than 65 years of age diagnosed with ALL from 2010 to 2016. OS was estimated for each group using the Kaplan Meier curves and compared based on insurance type using a log-rank test. Multivariate analysis using Cox proportional hazard regression model was used to assess the effect of insurance status on OS. RESULTS: A total of 9057 patients were included in the analysis. Medicaid beneficiaries had worse 5-year OS than insured patients (HR 1.33, 95% CI 1.08-1.63, P = .006) in 0-18 years age group. Despite chemotherapy, patients older than 18 years showed poor OS in all insurance categories. Patients on Medicaid showed inferior OS compared to insured in 19-40 years (HR 1.46, 95% CI 1.21-1.76, P < .001) and 41-65 years age group (HR 1.27, 95% CI 1.09-1.49, P = .003). Interestingly, no significant difference was observed in the OS between the Medicaid and uninsured groups in each age category. CONCLUSION: Our large database study demonstrates that insured status is associated with better OS in ALL across all age groups. Further studies to develop effective strategies to bridge health care disparities areessential.

Special considerations in the management of adult patients with acute leukaemias and myeloid neoplasms in the COVID-19 era: recommendations from a panel of international experts.

The ongoing COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 is a global public health crisis. Multiple observations indicate poorer post-infection outcomes for patients with cancer than for the general population. Herein, we highlight the challenges in caring for patients with acute leukaemias and myeloid neoplasms amid the COVID-19 pandemic. We summarise key changes related to service allocation, clinical and supportive care, clinical trial participation, and ethical considerations regarding the use of lifesaving measures for these patients. We recognise that these recommendations might be more applicable to high-income countries and might not be generalisable because of regional differences in health-care infrastructure, individual circumstances, and a complex and highly fluid health-care environment. Despite these limitations, we aim to provide a general framework for the care of patients with acute leukaemias and myeloid neoplasms during the COVID-19 pandemic on the basis of recommendations from international experts.

Personalizing therapy for older adults with acute myeloid leukemia: Role of geriatric assessment and genetic profiling.

Acute myeloid leukemia (AML) presents therapeutic challenges in older adults because of high-risk leukemia biology conferring chemoresistance, and poor functional status resulting in increased therapy-related toxicities. Recent FDA approval of 8 new drugs for AML has increased therapeutic armamentarium and also provides effective low-intensity treatment options. Rational therapy selection strategies that consider individual's risk of therapy-related toxicities and probability of disease control can maximize benefits of available treatments. Studies have demonstrated that fitness level, measured by geriatric assessment can predict therapy-related toxicities, whereas cytogenetic and mutation results correlate with the probability of responses to standard chemotherapy. We are approaching an era when we move from "one size fits all" approach to personalized therapy selection based on geriatric assessment, genetic and molecular profiling.

Socioeconomic and health system factors associated with lower utilization of hematopoietic cell transplantation in older patients with acute myeloid leukemia.

Receipt of hematopoietic cell transplantation (HCT) can improve overall survival in older patients with intermediate or high-risk acute myeloid leukemia (AML); however, utilization of HCT is poor. It is important to understand the factors that affect the receipt of HCT in a real-world setting among the older patients. We utilized the National Cancer Database to determine receipt of HCT in older patients (61-75 years) with intermediate or high-risk AML reported between 2003 and 2012. Multivariate logistic regression analysis was used to determine factors associated with receipt of HCT. Only 5.5% of older patients (n = 17,555) underwent HCT. Factors associated with a lower likelihood of receiving HCT included receipt of care in a non-academic hospital, race other than white, older age, Charlson comorbidity score of ≥1, uninsured status, Medicaid or Medicare insurance, and lower educational status. The receipt of HCT in older patients is low and varies based on biological as well as non-biologic factors, such as hospital type, insurance, and educational status. Nationwide efforts to improve access to HCT for appropriate patients are necessary.

Medical and Economic Burden of Heparin-Induced Thrombocytopenia: A Retrospective Nationwide Inpatient Sample (NIS) Study.

In recent years, US hospitals have switched from use of unfractionated heparin to use of low-molecular-weight heparin, which is associated with lower risk of heparin-induced thrombocytopenia (HIT). In the study reported here, we retrospectively searched the Nationwide Inpatient Sample (NIS) for patients who were at least 18 years old and received a diagnosis of HIT between 2009 and 2011. Our goal was to get an updated perspective on the incidence and economic impact of HIT. We calculated the incidence of HIT overall and in subgroups of patients who underwent cardiac, vascular, or orthopedic surgery. We compared characteristics of patients with and without HIT and compared characteristics of patients with HIT with thrombosis (HITT) and HIT patients without thrombosis. Of 98,636,364 hospitalizations, 72,515 (0.07%) involved HIT. Arterial and venous thromboses were identified in 24,880 (34.3%) of HIT cases. Men were slightly more likely to have a HIT diagnosis (50.1%), but women had higher rates of HIT after cardiac surgery (odds ratio [OR], 1.41; 95% confidence interval [CI], 1.26-1.58) and vascular surgery (OR, 1.42; 95% CI, 1.29-1.57). Rates of HIT were 0.53% (95% CI, 0.51%-0.54%) after cardiac surgery, 0.28% (95% CI, 0.28%-0.29%) after vascular surgery, and 0.05% (95% CI, 0.05%-0.06%) after orthopedic surgery. HIT and HITT cases were significantly (P ⟨ 0.001) more likely than non-HIT cases to be fatal (9.63% and 12.28% vs 2.19%), and they had significantly higher costs and longer inpatient stays. HIT and especially HITT are associated with increased mortality, costs, and length of stay. Journal of Hospital Medicine 2017;12:94-97.

Time to Insurance Approval in Private and Public Payers Does Not Influence Survival in Patients Who Undergo Hematopoietic Cell Transplantation.

In the United States, insurance status has been implicated as a barrier to obtaining timely treatment. In this retrospective cohort study of 521 patients who underwent first hematopoietic cell transplantation (HCT), we investigated the association between timeliness of HCT and overall survival. Timeliness was operationally defined in the following 3 ways: (1) payer approval, from request for approval to actual payer approval; (2) transplantation speed, from payer approval to time of actual HCT; and (3) total time, from request for approval to HCT. Patients with private insurance had longer time to payer approval (P < .0001) than those with public payers but shorter time from approval to actual HCT (P < .0001) and total time to HCT (P < .0001). Multivariate Cox regression showed no significant differences in risk of death between slow and fast times in the 3 indices of timeliness in the models that used all patients (n = 509), autologous HCT in lymphoma (n = 278), and autologous HCT in multiple myeloma (n = 121). Additional studies to evaluate the effect of insurance timeliness on all patients for whom HCT is recommended, not just those who undergo HCT, should be conducted.

Mortality, length of stay, and health care costs of febrile neutropenia-related hospitalizations among patients with breast cancer in the United States.

PURPOSE: Febrile neutropenia is a potentially life threatening complication of breast cancer chemotherapy associated with a significant amount of morbidity, mortality, and health care resource utilization. Recent data on the national estimates of mortality rate, length of stay, and health care costs among the subpopulation of febrile neutropenia admissions with breast cancer are lacking. METHODS: We used the Nationwide Inpatient Sample database to identify patients with breast cancer hospitalized for febrile neutropenia from 2009 to 2011. We derived data on inhospital mortality rate, length of stay, and mean health care costs and compared it with previous studies. RESULTS: The average inhospital mortality rate during 2009-2011 was 2.6 % (n = 685). Advanced age (≥ 65 years) was found to be significantly associated with a higher odds of mortality (4.4 vs 1.7 %, OR 2.7, 95 % CI 2.3-3.1, p < 0.01). The mean length of stay was 5.7 days (95 % CI 5.5-5.9 days), whereas the mean cost of hospitalization was $37,087 (95 % CI $34,009-$40,165). CONCLUSION: Febrile neutropenia-related hospitalizations continue to account for significant morbidity, mortality, and health care resource utilization among patients with breast cancer. Further efforts should be focused on curtailing the rising health care costs without compromising the quality of care.
