Sampagar A, Patil NG, Reddy NA, Dias M. ALL induction outcome: Real-world data from a pediatric oncology center in an LMIC setup with rural predominance. Indian J Cancer 2024; 61:215-223. [PMID: 38217488 DOI: 10.4103/ijc.ijc_355_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Accepted: 09/14/2021] [Indexed: 01/15/2024]
Abstract
BACKGROUND Acute lymphoblastic leukemia (ALL) has survival rates of greater than 90% in developed nations. However, various sociodemographic factors adversely affect outcome rates in low- and middle-income countries (LMICs). OBJECTIVE To study induction outcome of ALL and various factors affecting it. METHODS This was a prospective cohort study which enrolled 86 children up to the age of 18 years with newly diagnosed ALL registered in newly established pediatric hematology and oncology division over the duration of 3 years. Sociodemographic and clinical data was collected. Outcome was assessed using morphological remission, minimal residual disease (MRD) and mortality rate. RESULTS Of the 170 children with malignancies registered, 86 were ALL. Mean age was 7.09 ± 4.07 years and the M: F ratio of 1.32:1. Sixteen (38.09%) of them had severe acute malnutrition and another 16 (38.09%) had moderate acute malnutrition. Thirty (68.18%) children over 5 years were undernourished. Seventy-four (86.05%) were B-ALL and 12 (13.95%) T-ALL. In total, 28.77% had WBC counts greater than 50 × 10 9 /L. t (12;21) was the most common cytogenetic abnormality. Majority (60.46%) of the patients belonged to lower socioeconomic status. Seventy-one (93.42%) patients completed induction of which 100% attained morphological remission and 64 (90.14%) were MRD negative. There were five mortalities, three (60%) due to sepsis and 2 (40%) due to hemophagocytic lymphohistiocytosis. Fifty (65.78%) children had morbidities during induction, febrile neutropenia being the commonest. CONCLUSIONS Successful induction outcome rates at par with high-income countries can be achieved even in resource-limited settings of LMIC with support from government and NGOs. Decentralized cancer care centers can effectively pave the way in reducing cancer mortality in children of lower socioeconomic status residing in rural areas.

Leuk Lymphoma 2023; 64:1304-1314. [PMID: 37165575 DOI: 10.1080/10428194.2023.2205976] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 04/11/2023] [Accepted: 04/14/2023] [Indexed: 05/12/2023]
Abstract
The St Jude Total Therapy Study XV was the first clinical trial to prospectively use minimal residual disease levels during and after remission induction therapy to guide risk-directed treatment. We used the Total Therapy XV protocol with minimal modification in treating 115 newly diagnosed pediatric acute lymphoblastic leukemia patients from low- and middle-income groups from January 2011 to December 2017. The mean age at diagnosis was 5.97 ± 3.96 years. The median follow-up period was 88 months. Three (2.6%) patients had bone marrow relapse, and one (0.87%) had an isolated central nervous system relapse. Nineteen of the patients (16.52%) died due to infection-related complications, three (2.61%) died due to progressive disease, and one (0.87%) died due to hematopoietic stem cell transplant complications. Five-year overall survival was 80%, and event-free survival was 78.3%. Our results showed that the Total XV treatment protocol could be used successfully in patients with ALL from low- and middle-income populations. However, infection-related deaths remain a significant problem.

Comparative effectiveness and safety of antibiotic prophylaxis during induction chemotherapy in children with acute leukaemia: a systematic review and meta-analysis. J Hosp Infect 2023; 136:20-29. [PMID: 36921630 DOI: 10.1016/j.jhin.2023.03.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Revised: 02/20/2023] [Accepted: 03/06/2023] [Indexed: 03/14/2023]
Abstract
BACKGROUND Bacterial infections are common during induction therapy in children and adolescents with acute leukaemia and may cause infection-related mortality. AIM To determine the efficacy and safety of prophylactic antibiotics in paediatric patients with acute leukaemia receiving induction chemotherapy. METHODS From three English databases and four Chinese databases, we searched for randomized controlled trials (RCTs) and cohort studies that compared prophylactic antibiotics to placebo, no prophylaxis, or that compared one antibiotic versus another in paediatric patients with acute leukaemia undergoing induction chemotherapy. Two reviewers independently screened the studies, extracted data, and assessed the risk of bias using Cochrane Risk of Bias 2 tool and Newcastle-Ottawa Scale, and the certainty of evidence using Grading of Recommendations Assessment, Development, and Evaluation (GRADE). FINDINGS Two RCTs and ten cohort studies were finally included. For children with acute lymphoblastic leukaemia, antibiotic prophylaxis, including levofloxacin, sulfamethoxazole-trimethoprim, or other antibiotics, probably reduced bacteraemia (risk ratio (RR): 0.44; 95% confidence interval (CI): 0.33-0.60; moderate certainty) without significantly increasing Clostridioides difficile infection (CDI) or invasive fungal infection. Levofloxacin reduced the CDI rate (RR: 0.08; 95% CI: 0.01-0.62; high certainty). Ciprofloxacin prophylaxis probably reduced infection-related mortality (RR: 0.12; 95% CI: 0.01-0.97; moderate certainty). In children with acute myeloid leukaemia, ciprofloxacin plus vancomycin may reduce febrile neutropenia (RR: 0.79; 95% CI: 0.66-0.94; low certainty). Individual studies indicated that prophylaxis increased antibiotic exposure but reduced non-preventive antibiotic exposure. CONCLUSION In children with acute leukaemia undergoing induction therapy, antibiotic prophylaxis may improve the bacterial infection and mortality.

Abstract
Introduction More than 85% of childhood malignancies occur in developing countries with less than a 30% cure rate as opposed to more than 80% cure rate in developed countries. This disproportionately significant difference might be due to delays in diagnosis, treatment initiation, lack of adequate supportive care, and treatment abandonment. We aimed to determine the impact of overall treatment delay on induction mortality of children with acute lymphoblastic leukemia treated at Tikur Anbessa specialized hospital (TASH). Methods A cross-sectional study was conducted among children who were treated from 2016 to 2019. Children with Down syndrome and relapsed leukemia were excluded from this study. Results A total of 166 children were included; most patients were males (71.7%). The mean age at diagnosis was 5.9 years. The median time interval from the onset of symptoms to the first TASH visit was 30 days and the median period from TASH's first clinic visit to diagnosis was 11 days. The median time to initiate chemotherapy after diagnosis was 8 days. The total median time from the first onset of symptoms to chemotherapy initiation was 53.5 days. Induction mortality was 31.3%. High-risk ALL and patients with an overall delay between 30 and 90 days were more likely to experience induction mortality. Discussion Patient and healthcare system delay is high compared to most studies done and a significant association has been noted with induction mortality. Efforts to expand the pediatric oncology service in the country and efficient diagnostic and treatment approach need to be established to reduce mortality associated with overall delay.

Costs associated with adverse events from remission induction for children with Acute Lymphoblastic Leukemia (ALL). BMC Health Serv Res 2022; 22:1522. [DOI: 10.1186/s12913-022-08676-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2022] [Accepted: 10/10/2022] [Indexed: 12/15/2022] Open
Abstract
Abstract
Background
ALL is the most frequent hematological tumor in children, so during remission induction chemotherapy protocol (RICP) adverse events (AEs) may appear. The public program in Mexico in charge of financial support to oncologic children without social security delivered a fix amount for ALL chemotherapy, but additional money needed to treat any other unexpected condition should be taken from the budget of the oncologic healthcare providers. So the purpose of our study was to estimate and evaluate the direct medical costs associated to EAs during RICP in children with ALL.
Methods
This study was retrospective, longitudinal, and observational based on medical records review of patients in RICP. The CTCAE was used to identify and classify AEs according to a SOC category. We focused on extracting resources data that were consumed both for inpatients and outpatients AEs. A micro-costing approach was adopted which involve quantification of each healthcare resource consumed by the hospital multiplying them by unit cost. The probability distributions of data were evaluated to identify the appropriated statistical tests to be used for comparisons between groups that were performed with Wilcoxon rank sum test. Generalized linear models (GLM) were adjusted to evaluate the effects of patient characteristics on total cost.
Results
Forty patients accumulated 204 inpatient and 81 outpatient AEs during RICP. Comparison of total costs between groups showed an incremental cost of $7,460.23 likewise attributable to AEs. The total cost of a pediatric patient undergoing RICP without adverse events was $3,078.36 and the total cost of a patient with AEs exceeds it threefold.
Conclusions
The costs associated with AEs during RICP in Mexican children with ALL representing a high burden for the healthcare provider. Generalized linear models showed that variables such as sex, risk category and alive status are associated with the total costs of AEs. This is the first study aiming to analyze the effect of ALL-related AEs on health care costs in pediatric population, so our results may help not only to local decision making but also it may contribute to the research agenda in this field.

Abstract
INTRODUCTION Our objectives were to design and validate methods to identify relapse and hematopoietic stem cell transplantation (HSCT) in children with acute lymphoblastic leukemia (ALL) using administrative data representing hospitalizations at US pediatric institutions. METHODS We developed daily billing and ICD-9 code definitions to identify relapses and HSCTs within a cohort of children with newly diagnosed ALL between January 1, 2004, and December 31, 2013, previously assembled from the Pediatric Health Information System (PHIS) database. Chart review for children with ALL at the Children's Hospital of Philadelphia (CHOP) and Texas Children's Hospital (TCH) was performed to establish relapse and HSCT gold standards for sensitivity and positive predictive value (PPV) calculations. We estimated incidences of relapse and HSCT in the PHIS ALL cohort. RESULTS We identified 362 CHOP and 314 TCH ALL patients in PHIS and established true positives by chart review. Sensitivity and PPV for identifying both relapse and HSCT in PHIS were > 90% at both hospitals. Five-year relapse incidence in the 10 150-patient PHIS cohort was 10.3% (95% CI 9.8%-10.9%) with 7.1% (6.6%-7.6%) of children underwent HSCTs. Patients in higher-risk demographic groups had higher relapse and HSCT rates. Our analysis also identified differences in incidences of relapse and HSCT by race, ethnicity, and insurance status. CONCLUSIONS Administrative data can be used to identify relapse and HSCT accurately in children with ALL whether they occur on- or off-therapy, in contrast with published approaches. This method has wide potential applicability for estimating these incidences in pediatric ALL, including patients not enrolled on clinical trials.

Abstract
BACKGROUND Treatment of infants with acute leukemia remains challenging, especially for acute lymphocytic leukemia (ALL). Infants have shown markedly higher rates of induction mortality compared with noninfants. There are limited data on presentation acuity and supportive care utilization in this age group. METHODS In retrospective analyses of patients treated for new onset ALL or acute myeloid leukemia (AML) at pediatric hospitals contributing to the Pediatric Health Information System, we compared presentation acuity, induction mortality, and resource utilization in infants relative to noninfants less than 10 years at diagnosis. RESULTS Analyses included 10 359 children with ALL (405 infants, 9954 noninfants) and 871 AML (189 infants, 682 noninfants). Infants were more likely to present with multisystem organ failure compared to noninfants for both ALL (12% and 1%, PR = 10.8, 95% CI: 7.4, 15.7) and AML (6% vs. 3%; PR = 2.0, 95% CI: 1.0, 3.7). Infants with ALL had higher induction mortality compared to noninfants, even after accounting for differences in anthracycline exposure and presentation acuity (2.7% vs. 0.5%, HR = 2.1, 95% CI: 1.0, 4.8). Conversely, infants and noninfants with AML had similar rates of induction mortality (3.2% vs. 2.1%, HR = 1.2, 95% CI: 0.3, 3.9), which were comparable to rates among infants with ALL. Infants with ALL and AML had greater requirements for blood products, diuretics, supplemental oxygen, and ventilation during induction relative to noninfants. CONCLUSIONS Infants with leukemia present with higher acuity compared with noninfants. Induction mortality and supportive care requirements for infants with ALL were similar to all children with AML, and significantly higher than those for noninfants with ALL.

Abstract
Abstract
Background Treatment protocols for acute lymphoblastic leukemia (ALL) have evolved over time to give excellent cure rates in children and moderate outcomes in adults; however, little is known how delays in chemotherapy affect long-term survival.
Objectives To find the association of delays during different treatment phases on the survival outcomes.
Materials and Methods Data from 149 ALL cases treated between 2009 and 2015 were retrospectively analyzed. Treatment course in commonly used protocols was divided into three phases—induction, consolidation (postremission), maintenance, and also a combined intensive phase (induction plus consolidation) for the purpose of analysis, and delay in each phase was defined based on clinically acceptable breaks. Analysis was done to find the impact of treatment delay in each phase on the survival outcomes.
Results The median age was 12 years (range, 1–57). Multi-center Protocol-841 (MCP-841) was used for 72%, German Multicenter Study Group for Adult ALL (GMALL) for 19%, and Berlin, Frankfurt, Muenster, 95 protocol (BFM-95) for 9% of patients. Delay in induction was seen in 52%, consolidation in 66%, and during maintenance in 42% of patients. The median follow-up was 41 months, and 3-year survival outcomes for the entire cohort were event-free survival (EFS)—60%, relapse-free survival (RFS)—72%, and overall survival (OS)—68%. On univariate analysis, delay in induction adversely affected EFS (hazard ratio [HR] = 1.78, p = 0.04), while delay in intensive phase had significantly worse EFS and RFS (HR = 2.41 [p = 0.03] and HR = 2.57 [p = 0.03], respectively). On separate analysis of MCP-841 cohort, delay in intensive phase affected both EFS (HR = 3.85, p = 0.02) and RFS (HR = 3.42, p = 0.04), whereas delay in consolidation significantly affected OS with (HR = 4.74, p = 0.04) independently.
Conclusion Treatment delays mostly in intensive phase are associated with worse survival in ALL; attempts should be made to maintain protocol-defined treatment intensity while adequately managing toxicities.

In-Hospital Management Might Reduce Induction Deaths in Pediatric Patients With Acute Lymphoblastic Leukemia: Results From a Japanese Cohort. J Pediatr Hematol Oncol 2021; 43:39-46. [PMID: 32852400 DOI: 10.1097/mph.0000000000001926] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2020] [Accepted: 06/15/2020] [Indexed: 11/25/2022]
Abstract
Induction deaths (ID) remain a critical issue in the treatment of pediatric patients with acute lymphoblastic leukemia (ALL). The reported rate of ID in this population is 1% or higher. We speculate that this proportion might be lower in Japan because of mandatory hospitalization during induction therapy to manage complications. We retrospectively analyzed the incidence of ID among children with ALL enrolled in 4 Japanese study groups between 1994 and 2013. Among 5620 children, 41 (0.73%) cases of ID were noted. The median age was 6.5 years; 24 children were female, and 7 had T-cell ALL. Infection was the most common cause of ID (n=22), but the incidence (0.39%) was lower than that reported in western countries. Mortality within 48 hours from the onset of infection was low, comprising 25% of infection-related deaths. The incidence of infections caused by Bacillus species was low. Only 1 patient died because of Aspergillus infection. Fatal infections mostly occurred during the third week of induction therapy. Our findings suggest that close monitoring, stringent infection control, and immediate administration of appropriate antibiotics through hospitalization might be important strategies in reducing the rate of infection-related ID in pediatric patients with ALL.

Abstract
BACKGROUND Socioeconomic and demographic categories such as income, race, insurance status, and treatment center type are associated with outcomes in acute leukemia. This study was aimed at determining whether the distance to treatment center affects overall survival for children and young adults with acute leukemia. METHODS The National Cancer Database was queried for patients 39 years old or younger who were diagnosed with acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL). A backward elimination procedure was used to select final multivariate Cox models. RESULTS In total, 12,301 patients with AML and 22,683 patients with ALL were analyzed. The ALL model included distance to treatment center, Charlson-Deyo score, age, race, insurance status, and community income level. US census definitions of urban and rural were not statistically significant, and no interaction was significant for included variables. Compared with distances > 50 miles, all other distances were associated with improved survival (hazard ratio [HR] for ≤10 miles, 0.91; P = .04; HR for >10 to ≤20 miles, 0.86; P = .004; HR for >20 to ≤50 miles, 0.87; P = .005). The final model for AML included the same variables as the ALL model except for distance to treatment center, which was not statistically significant. CONCLUSIONS For children and young adults with ALL, distances > 50 miles are associated with inferior overall survival; however, no difference is seen for AML. Although it is unknown whether differences in survival for patients with ALL based on distance are driven by relapse or treatment-related mortality, increased attention to adherence, supportive care, and logistics for patients traveling long distances is warranted. LAY SUMMARY For children and young adults with acute lymphoblastic leukemia, living more than 50 miles from the treatment center is associated with worse outcomes.

Abstract
OBJECTIVES Acute lymphoblastic leukemia (ALL) with CNS2 status predicts inferior outcome and a high rate of CNS relapse, similar to overt CNS leukemia (CNS3). The purpose of this study was to determine if intrathecal (IT) dose intensification during induction would improve outcomes and reduce CNS relapse for CNS2 disease. METHODS From January 2001 to December 2014, children (1-14 years) with newly diagnosed ALL were treated at the Princess Noorah Oncology Centre (PNOC) following modifications of the Children's Oncology Group (COG) protocols. We intensified IT methotrexate (ITM) during induction for patients with CNS2 disease. Patients were evaluated for overall survival (OS), disease-free survival (DFS), and cumulative incidence of relapse (CIR). RESULTS 449 children with T-cell (14.3%) or B-cell (85.7%) ALL were treated using PNOC-SR or PNOC-HR regimens (Jan 2001- Dec 2007) or CALL08 regimens (Arm A [SR], Arm B [IR], and Arm C [HR]) (Jan 2008 - Dec 2014). The 5-year OS, DFS, and CIR were 87.2 ± 1.6%, 81.7 ± 1.9%, and 13.0 ± 1.7%, respectively. The OS and DFS of patients with CNS2 were significantly superior to that of patients with CNS3 (P = 0.025 and P = 0.019, respectively). Patients with CNS2 had similar OS and DFS to those with CNS1. None of the patients with CNS2 at initial diagnosis experienced CNS relapse. CONCLUSIONS ITM intensification during induction was associated with elimination of CNS recurrence in patients with CNS2 disease and childhood ALL. Controlled studies are needed to confirm this observation.

Abstract
Despite substantial improvements in survival from childhood cancer during the last decades, there are indications that survival rates for several cancer types are no longer improving. Moreover, evidence accumulates suggesting that socioeconomic and sociodemographic factors may have an impact on survival also in high-income countries. The aim of this review is to summarize the findings from studies on social factors and survival in childhood cancer. Several types of cancer and social factors are included in order to shed light on potential mechanisms and identify particularly affected groups. A literature search conducted in PubMed identified 333 articles published from December 2012 until June 2018, of which 24 fulfilled the inclusion criteria. The findings are diverse; some studies found no associations but several indicated a social gradient with higher mortality among children from families of lower socioeconomic status (SES). There were no clear suggestions of particularly vulnerable subgroups, but hematological malignancies were most commonly investigated. A wide range of social factors have been examined and seem to be of different importance and varying between studies. However, potential underlying mechanisms linking a specific social factor to childhood cancer survival was seldom described. This review provides some support for a relationship between lower parental SES and worse survival after childhood cancer, which is a finding that needs further attention. Studies investigating predefined hypotheses involving specific social factors within homogenous cancer types are lacking and would increase the understanding of mechanisms involved, and allow targeted interventions to reduce health inequalities.

Abstract
Data routinely collected through United Network for Organ Sharing (UNOS) lack the detailed information on medical resource utilization and treatment costs required to accomplish for center-level comparisons of quality of care and cost for pediatric heart transplantation. We aimed to overcome this limitation by merging UNOS with the Pediatric Health Information System (PHIS) database, an administrative database containing inpatient, emergency department, ambulatory surgery, and observation unit information from over 40 not-for-profit, tertiary care pediatric hospitals. Utilizing a probabilistic match based on center, date of birth, recipient gender, and transplant date within ±2 days, more than 90% of eligible UNOS patients (N = 2264) were successfully merged to their corresponding PHIS records. Thirty-day and 1-year mortality rates observed for the merged cohort (3.2% and 9.0%, respectively) were compared with those previously reported for pediatric heart transplants, as were the significant predictors of increased mortality. These results demonstrate that the established UNOS-PHIS cohort will provide a valid platform for subsequent research aimed at identifying center-level differences that could be exploited to optimize quality of care while minimizing cost across institutions.

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.

Abstract
Background We examined incidence and survival in relation to age, gender, socioeconomic deprivation, rurality and trends over time. We also examined the association between volume of patients treated by hospitals and survival. Methods Incident cases (2001–12) were identified using comprehensive National Health Service admissions data for England, with follow-up to March 2013. Socioeconomic deprivation was based on census area of residence. Volume was assessed in a three-year subset of the data with consistent hospital provider codes. Results There were 2921 adults aged 18 or more years diagnosed with acute lymphoblastic leukaemia (ALL) in the 12-year time span, giving a crude annual incidence of 0.61/100,000 population. Five-year survival was 32% (1870 deaths). Compared with patients living in least deprived areas, survival was worse for patients living in intermediate and most deprived areas, with mortality hazard ratios 21% (95% CI 8–35%) and 16% (95% CI 3–30%) higher respectively. Hospitals treating low volumes of adults with ALL were associated with poorer survival. The adjusted mortality hazard ratio in this subset of 465 patients was 33% (95% CI 3–73%) higher in low volume hospitals. There was no evidence of association between socioeconomic deprivation and incidence. Rurality did not appear to be associated with incidence or survival. Incidence was higher in men but there was no evidence of a gender difference in survival. Survival improved over time. Conclusion The associations between socioeconomic deprivation and survival and between volume and outcome for adults with ALL, if confirmed, are likely to have significant implications for the organisation of services for adults with ALL.

Abstract
The Affordable Care Act of 2010 launch of Medicare Value-Based Purchasing has become the platform for payment reform. It is a mechanism by which buyers of health care services hold providers accountable for high-quality and cost-effective care. The objective of the study was to examine the relationship between quality of hospital care and hospital competition using the quality-quantity behavioral model of hospital behavior. The quality-quantity behavioral model of hospital behavior was used as the conceptual framework for this study. Data from the American Hospital Association database, the Hospital Compare database, and the Area Health Resources Files database were used. Multivariate regression analysis was used to examine the effect of hospital competition on patient mortality. Hospital market competition was significantly and negatively related to the 3 mortality rates. Consistent with the literature, hospitals located in more competitive markets had lower mortality rates for patients with acute myocardial infarction, heart failure, and pneumonia. The results suggest that hospitals may be more readily to compete on quality of care and patient outcomes. The findings are important because policies that seek to control and negatively influence a competitive hospital environment, such as Certificate of Need legislation, may negatively affect patient mortality rates. Therefore, policymakers should encourage the development of policies that facilitate a more competitive and transparent health care marketplace to potentially and significantly improve patient mortality.

Abstract
BACKGROUND There are few contemporary studies of volume-outcome relationships in pediatric oncology. Children with acute lymphoblastic leukemia (ALL) are treated at a wide variety of hospitals. We investigated if inpatient hospital volume influences outcomes. The objective of this study was to evaluate the relationship between inpatient pediatric and pediatric oncology volume and mortality and intensive care resources (ICU care). We hypothesized an inverse relationship between volume and these outcomes. PATIENTS AND METHODS This was a retrospective cohort study. Patients 0 to 18 years of age in the Pediatric Health Information System or Perspective Premier Database from 2009 to 2011 with ALL were included. Exposures were considered as the average inpatient pediatric and pediatric oncology volume. The primary outcome was inpatient mortality; secondary outcome was need for ICU care. RESULTS The included population comprised 3350 patients from 75 hospitals. The inpatient mortality rate was 0.86% (95% confidence interval, 0.58%-1.2%). In the unadjusted analysis, mortality increased as pediatric oncology volume increased from low (0%) to high volume (1.3%) (P = .009). The small number of deaths precluded multivariable analysis of this outcome. Pediatric and pediatric oncology volume was not associated with ICU care when we controlled for potential confounders. CONCLUSION Induction mortality was low. We did not observe an inverse relationship between volume and mortality or ICU care. This suggests that in a modern treatment era, treatment at a low-volume center might not be associated with increased mortality or ICU care in the first portion of therapy. This relationship should be evaluated in other oncology populations with higher mortality rates and with longer-term outcomes.
