Background: Gastrostomy tube (G-tube) placement for children with neurologic impairment with dysphagia has been suggested for pneumonia prevention. However, prior studies demonstrated an association between G-tube placement and increased risk of pneumonia. We evaluate the association between timing of G-tube placement and death or severe pneumonia in children with neurologic impairment. Methods: We included all children enrolled in California Children’s Services between July 1, 2009, and June 30, 2014, with neurologic impairment and 1 pneumonia hospitalization. Prior to analysis, children with new G-tubes and those without were 1:2 propensity score matched on sociodemographics, medical complexity, and severity of index hospitalization. We used a time-varying Cox proportional hazard model for subsequent death or composite outcome of death or severe pneumonia to compare those with new G-tubes vs those without, adjusting for covariates described above. Results: A total of 2490 children met eligibility criteria, of whom 219 (9%) died and 789 (32%) had severe pneumonia. Compared to children without G-tubes, children with new G-tubes had decreased risk of death (hazard ratio [HR] 0.47, 95% confidence interval [CI] 0.39-0.55) but increased risk of the composite outcome (HR 1.21, CI 1.14-1.27). Sensitivity analyses using varied time criteria for definitions of G-tube and outcome found that more recent G-tube placement had greater associated risk reduction for death but increased risk of severe pneumonia. Conclusion: Recent G-tube placement is associated with reduced risk of death but increased risk of severe pneumonia. Decisions to place G-tubes for pulmonary indications in children with neurologic impairment should weigh the impact of severe pneumonia on quality of life.

Background Studies of adolescent and young adult (AYA) oncology end-of-life care utilization are critical because cancer is the leading cause of nonaccidental AYA death and end-of-life care contributes significantly to health care expenditures. This study was designed to determine the quantity of and disparities in inpatient utilization in the last year of life of AYAs with cancer. Methods The California Office of Statewide Health Planning and Development administrative discharge database, linked to death certificates, was used to perform a population-based analysis of cancer patients aged 15 to 39 years who died in 2000-2011. The number of hospital days and the inpatient costs were determined for each patient in the last year of his or her life, as were clinical and sociodemographic factors associated with high inpatient utilization. Admission patterns as death approached were also evaluated. Results The 12,883 patients were admitted for 40 days on average in the last year of life, and this cost $151,072 per patient in inpatient costs. As death approached, the admission rates and the percentage of all admissions occurring at nonspecialty centers increased. Five percent of patients used 20% of bed days in the last year (high utilizers). Factors associated with high utilization included younger age (15-30 years), Hispanic ethnicity, non-health maintenance organization insurance, and hematologic malignancies. Conclusions AYA oncology decedents were admitted for 40 days in their last year of life. Subgroups with high utilization had distinct sociodemographic and clinical characteristics, and nonspecialty center admissions increased as death approached. This demonstrates the need for palliative care at nonspecialty centers. Future studies need to determine whether these patterns are goal-concurrent, include high utilizers, and monitor the effects of health care reform.

Purpose: Cancer is the leading cause of nonaccidental death among adolescents and young adults (AYAs). High-intensity end-of-life care is expensive and may not be consistent with patient goals. However, the intensity of end-of-life care for AYA decedents with cancer—especially the effect of care received at specialty versus nonspecialty centers—remains understudied. Methods: We conducted a retrospective, population-based analysis with the California administrative discharge database that is linked to death certificates. The cohort included Californians age 15 to 39 years who died between 2000 and 2011 with cancer. Intense end-of-life interventions included readmission, admission to an intensive care unit, intubation in the last month of life, and in-hospital death. Specialty centers were defined as Children’s Oncology Group centers and National Cancer Institute–designated comprehensive cancer centers. Results: Of the 12,938 AYA cancer decedents, 59% received at least one intense end-of-life care intervention, and 30% received two or more. Patients treated at nonspecialty centers were more likely than those at specialty-care centers to receive two or more intense interventions (odds ratio [OR], 1.46; 95% CI, 1.32 to 1.62). Sociodemographic and clinical factors associated with two or more intense interventions included minority race/ethnicity (Black [OR, 1.35, 95% CI, 1.17 to 1.56]; Hispanic [OR, 1.24; 95% CI, 1.12 to 1.36]; non-Hispanic white: reference), younger age (15 to 21 years [OR, 1.36; 95% CI, 1.19 to 1.56; 22 to 29 years [OR,1.26; 95% CI,1.14 to 1.39]; ≥ 30 years: reference), and hematologic malignancies (OR, 1.53; 95% CI, 1.41 to 1.66; solid tumors: reference). Conclusion: Thirty percent of AYA cancer decedents received two or more high-intensity end-of-life interventions. In addition to sociodemographic and clinical characteristics, hospitalization in a nonspecialty center was associated with high-intensity end-of-life care. Additional research is needed to determine if these disparities are consistent with patient preference.

BACKGROUND Patients with a terminal illness should have access to their chosen location of death. Cancer is the leading cause of non-accidental death among adolescents and young adults (AYAs; those aged 15-39 years). Although surveys have suggested that a majority of these patients prefer a home death, to the authors' knowledge, little is known regarding their barriers to accessing their preferred location of death. As a first step, the authors sought to determine, across a large population, 20-year trends in the location of death among AYA patients with cancer. METHODS Using the Vital Statistics Death Certificate Database of the California Office of Statewide Health Planning and Development, the authors performed a retrospective, population-based analysis of California patients with cancer aged 15 to 39 years who died between 1989 and 2011. Sociodemographic and clinical factors associated with hospital death were examined using multivariable logistic regression. RESULTS Of 30,573 AYA oncology decedents, 57% died in a hospital, 33% died at home, and 10% died in other locations (eg, hospice facility or nursing facility). Between 1989 and 1994, hospital death rates decreased from 68.3% to 53.6% and at-home death rates increased from 16.8% to 35.5%. Between 1995 and 2011, these rates were stable. Those individuals who were more likely to die in a hospital were those aged

BACKGROUND: Children with neurologic impairment (NI) face high risk of recurrent severe pneumonia, with prevention strategies of unknown effectiveness. We evaluated the comparative effectiveness of secondary prevention strategies for severe pneumonia in children with NI. METHODS: We included children enrolled in California Children’s Services between July 1, 2009, and June 30, 2014, with NI and 1 pneumonia hospitalization. We examined associations between subsequent pneumonia hospitalization and expert-recommended prevention strategies: dental care, oral secretion management, gastric acid suppression, gastrostomy tube placement, chest physiotherapy, outpatient antibiotics before index hospitalization, and clinic visit before or after index hospitalization. We used a 1:2 propensity score matched model to adjust for covariates, including sociodemographics, medical complexity, and severity of index hospitalization. RESULTS: Among 3632 children with NI and index pneumonia hospitalization, 1362 (37.5%) had subsequent pneumonia hospitalization. Only dental care was associated with decreased risk of subsequent pneumonia hospitalization (adjusted odds ratio [aOR]: 0.64; 95% confidence interval [CI]: 0.49–0.85). Exposures associated with increased risk included gastrostomy tube placement (aOR: 2.15; 95% CI: 1.63–2.85), chest physiotherapy (aOR: 2.03; 95% CI: 1.29–3.20), outpatient antibiotics before hospitalization (aOR: 1.42; 95% CI: 1.06–1.92), clinic visit before (aOR: 1.30; 95% CI: 1.11–1.52), and after index hospitalization (aOR: 1.72; 95% CI: 1.35–2.20). CONCLUSIONS: Dental care was associated with decreased recurrence of severe pneumonia. Several strategies, including gastrostomy tube placement, were associated with increased recurrence, possibly due to unresolved confounding by indication. Our results support a clinical trial of dental care to prevent severe pneumonia in children with NI.

BACKGROUND Adolescents and young adults (AYAs) ages 15 to 39 years with cancer continue to experience disparate survival outcomes compared with their younger and older counterparts. This may be caused in part by differential access to specialized cancer centers (SCCs), because treatment at SCCs has been associated with improved overall survival. The authors examined social and clinical factors associated with AYA use of SCCs (defined as Children's Oncology Group-designated or National Cancer Institute-designated centers). METHODS A retrospective, population-based analysis was performed on all hospital admissions of AYA oncology patients in California during 1991 through 2014 (n = 127,250) using the Office of Statewide Health Planning and Development database. Multivariable logistic regression analyses examined the contribution of social and clinical factors on always receiving care from an SCC (vs sometimes or never). Results are presented as adjusted odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS Over the past 20 years, the percentage of patients always receiving inpatient care at an SCC increased over time (from 27% in 1991 to 43% in 2014). In multivariable regression analyses, AYA patients were less likely to always receive care from an SCC if they had public insurance (OR, 0.64; 95% CI, 0.62-0.66), were uninsured (OR, 0.51; 95% CI, 0.46-0.56), were Hispanic (OR, 0.88; 95% CI, 0.85-0.91), lived > 5 miles from an SCC, or had a diagnosis other than leukemia and central nervous system tumors. CONCLUSIONS Receiving care at an SCC was influenced by insurance, race/ethnicity, geography, and tumor type. Identifying the barriers associated with decreased SCC use is an important first step toward improving outcomes in AYA oncology patients. Cancer 2017;123:2516–23. © 2017 American Cancer Society.

We examined the use of Pediatric Cancer Specialty Centers (PCSCs) over time and the length of stay (LOS) in pediatric oncology patients with a diagnosis of febrile neutropenia. PCSCs were defined as Children's Oncology Group and California Children's Services designated centers. We performed a retrospective analysis on all discharges of pediatric (0 to 18) oncology patients with febrile neutropenia in California (1983 to 2011) using the private Office of Statewide Health Planning and Development database. We examined influence of age, sex, race/ethnicity, payer, income, distance, tumor type, and complications on utilization of PCSCs and LOS (SAS 9.2). Analysis of 24,559 pediatric oncology febrile neutropenia discharges showed hospitalizations in PCSCs increasing from 48% in 1983 to 94% in 2011. The adjusted regression analysis showed decreased PCSC utilization for ages 15 to 18, Hispanic patients, and those living40 miles away. The median PCSC LOS was 9 days compared with 7 days at a non-PCSC (P0.0001). Discharge from a PCSC was associated with a LOS8 days after controlling for complications. Inpatient PCSC care for febrile neutropenia in California has increased since 1983. Receiving care at a PCSC is influenced by age, tumor type, ethnicity, geography, and complications.

Background American Academy of Pediatrics guidelines emphasize regionalized systems of care for pediatric chronic illness. There remains a paucity of information on the status of regionalized systems of care for pediatric congenital heart disease (CHD). Objectives This study evaluated variations in use of pediatric cardiology specialty care centers (PCSCC) for pediatric patients with CHD in California between 1983 and 2011. Methods We performed a retrospective, total population analysis of pediatric CHD patients using the California Office of Statewide Health Planning and Development unmasked database. PCSCCs were identified by California's Title V program. Results There were 164,310 discharges meeting inclusion criterion. Discharges from PCSCCs grew from 58% to 88% between 1983 and 2011. Regionalized care was highest for surgical (96%) versus nonsurgical (71%) admissions. Admissions with a public payer increased from 42% (1983) to 61% (2011). Total bed days nearly doubled, and median length of stay increased from 2 to 3 days (nonspecialty care) and from 4 to 5 days (specialty care). There was a decrease in the pediatric CHD in-hospital death rate from 5.1 to 2.3 per 100,000 between 1983 and 2011, and a shift toward a larger percent of deaths occurring in the newborn period. Conclusions California’s inpatient regionalized specialty care of pediatric CHD has increased substantially since 1983, especially for surgical CHD discharges. The death rate has decreased, the number of bed days has increased, and a large proportion of these discharges now have public payers. Health care reform efforts must consider these shifts while protecting advances in regionalization of pediatric CHD care.

The American College of Cardiology and American Heart Association guidelines recommend that management of adult congenital heart disease (ACHD) be coordinated by specialty ACHD centers and that ACHD surgery for patients with moderate or complex congenital heart disease (CHD) be performed by surgeons with expertise and training in CHD. Given this, the aim of this study was to determine the proportion of ACHD surgery performed at specialty ACHD centers and to identify factors associated with ACHD surgery being performed outside of specialty centers. This retrospective population analysis used California's Office of Statewide Health Planning and Development's discharge database to analyze ACHD cardiac surgery (in patients 21 to 65 years of age) in California from 2000 to 2011. Designation as a "specialty ACHD center" was defined on the basis of a national ACHD directory. A total of 4,611 ACHD procedures were identified. The proportion of procedures in patients with moderate and complex CHD delivered at specialty centers increased from 46% to 71% from 2000 to 2011. In multivariate analysis among those discharges for ACHD surgery in patients with moderate or complex CHD, performance of surgery outside a specialty center was more likely to be associated with patients who were older, Hispanic, insured by health maintenance organizations, and living farther from a specialty center. In conclusion, although the proportion of ACHD surgery for moderate or complex CHD being performed at specialty ACHD centers has been increasing, 1 in 4 patients undergo surgery at nonspecialty centers. Increased awareness of ACHD care guidelines and of the patient characteristics associated with differential access to ACHD centers may help improve the delivery of appropriate care for all adults with CHD.

BACKGROUND: Many adult patients with cancer who know they are dying choose less intense care; additionally, high-intensity care is associated with worse caregiver outcomes. Little is known about intensity of end-of-life care in children with cancer. METHODS: By using the California Office of Statewide Health Planning and Development administrative database, we performed a population-based analysis of patients with cancer aged 0 to 21 who died between 2000 and 2011. Rates of and sociodemographic and clinical factors associated with previously-defined end-of-life intensity indicators were determined. The intensity indicators included an intense medical intervention (cardiopulmonary resuscitation, intubation, ICU admission, or hemodialysis) within 30 days of death, intravenous chemotherapy within 14 days of death, and hospital death. RESULTS: The 3732 patients were 34% non-Hispanic white, and 41% had hematologic malignancies. The most prevalent intensity indicators were hospital death (63%) and ICU admission (20%). Sixty-five percent had ≥1 intensity indicator, 23% ≥2, and 22% ≥1 intense medical intervention. There was a bimodal association between age and intensity: ages CONCLUSIONS: Nearly two-thirds of children who died of cancer experienced intense end-of-life care. Further research needs to determine if these rates and disparities are consistent with patient and/or family goals.

We performed a retrospective analysis of hospital discharges for children with autism, in comparison to children with cerebral palsy, Down syndrome, mental retardation/intellectual disability, and the general population. Hospitalizations for autism increased nearly threefold over 10 years, especially at the oldest ages, while hospitalizations for the other groups did not change. Leading discharge diagnoses for each age group in children with autism included mental health and nervous system disorders. Older age, Caucasian ethnicity, and living in a region with a high number of pediatric beds predicted hospitalizations associated with mental health diagnoses. These findings underscore the need for comprehensive clinical services that address the complex needs of children with autism to prevent costly hospitalizations.

BACKGROUND: Trauma centers (TCs) have been shown to decrease mortality in adults, but this has not been demonstrated at a population level in all children. We hypothesized that seriously injured children would have increased survival in a TC versus nontrauma center (nTC), but there would be no increased benefit from pediatric-designated versus adult TC care. METHODS: This was a retrospective study of the unmasked California Office of Statewide Health and Planning Department patient discharge database (1999-2011). DRG International Classification of Diseases-9th Rev. (ICD-9) diagnostic codes indicating trauma were identified for children (0-18 years), and injury severity was calculated from ICD-9 codes using validated algorithms. To adjust for hospital case mix, we selected patients with ICD-9 codes that were capable of causing death and which appeared at both TCs and nTCs. Instrumental variable (IV) analysis using differential distance between the child's residence to a TC and to the nearest hospital was applied to further adjust for unobservable differences in TC and nTC populations. Instrumental variable regression models analyzed the association between mortality and TC versus nTC care as well as for pediatric versus adult TC designations, adjusting for demographic and clinical variables. RESULTS: Unadjusted mortality for the entire population of children with nontrivial trauma (n = 445,236) was 1.2%. In the final study population (n = 77,874), mortality was 5.3%, 3.8% in nTCs and 6.1% in TCs. IV regression analysis demonstrated a 0.79 percentage point (95% confidence interval, -0.80 to -0.30; p = 0.044) decrease in mortality for children cared for in TC versus nTC. No decrease in mortality was demonstrated for children cared for in pediatric versus adult TCs. CONCLUSION: Our IV TC outcome models use improved injury severity and case mix adjustment to demonstrate decreased mortality for seriously injured California children treated in TCs. These results can be used to take evidence-based steps to decrease disparities in pediatric access to, and subsequent outcomes for, trauma care.

BACKGROUND. Studies from the early 1990s have documented greater intensity of treatment for patients with acute myocardial infarction (AMI) in the United States compared with Canada, with little difference in health outcomes. Little is known about whether treatments and outcomes are changing differently over time in the two countries, and whether the differences vary with patient age. METHODS. We conducted a retrospective cohort study of trends in cardiac procedure use, mortality, and recurrent AMI for patients 65 years or older hospitalized with AMI in the United States and Quebec. We examined Medicare claims and enrollment data from the United States (1.5 million) and provincial claims data from Quebec (35,000) between 1988 and 1994. RESULTS. Use of cardiac procedures grew more rapidly between 1988 and 1994 in the United States, particularly for patients 75 years or older; unlike in Quebec, these cardiac procedures were performed soon after AMI. Both countries experienced significant declines in 1-year mortality: the decline averaged 1.27% points per year in the United States and 1.05% points in Quebec (P = ns). For AMI patients 75 years or older, 30-day and 1-year mortality declined approximately twice as rapidly in the United States as in Quebec (P < 0.01). The decline in mortality in the United States relative to Canada was significantly greater among patients 75 years or older but not among those age 65 to 74 years. Readmission rates with recurrent AMI were almost unchanged. CONCLUSIONS. Over time, the use of cardiac procedures in elderly patients with AMI has risen more rapidly in the United States than in Quebec. These differences in procedure trends were associated with reductions in overall long-term AMI mortality in both countries.

PURPOSE: The purpose of the study was to describe inpatient hospitalization patterns among detained and nondetained youth in a large, total population of hospitalized adolescents in California. METHODS: We examined the unmasked California Office of Statewide Health Planning and Development Patient Discharge Dataset from 1997 to 2011. We considered hospitalized youth aged 11-18 years "detained" if admitted to California hospitals from detention, transferred from hospital to detention, or both. We compared discharge diagnoses and length of stay between detained youth and their nondetained counterparts in the general population. RESULTS: There were 11,367 hospitalizations for detained youth. Hospitalizations differed for detained versus nondetained youth: 63% of all detained youth had a primary diagnosis of mental health disorder (compared with 19.8% of nondetained youth). Detained girls were disproportionately affected, with 74% hospitalized for a primary mental health diagnosis. Detained youth hospitalized for mental health disorder had an increased median length of stay compared with nondetained inpatient youth with mental illness (≥6 days vs. 5 days, respectively). This group difference was heightened in the presence of minority status, public insurance, and concurrent substance abuse. Hospitalized detained youth discharged to chemical dependency treatment facilities had the longest hospital stays (≥43 days). CONCLUSIONS: Detained juvenile offenders are hospitalized for very different reasons than the general adolescent population. Mental illness, often with comorbid substance abuse, requiring long inpatient stays, represents the major cause for hospitalization. These findings underscore the urgent need for effective, well-coordinated mental health services for youth before, during, and after detention. Language: en

Background The use of coronary angiography and revascularization is lower than expected among black patients. It is uncertain whether use of other cardiac procedures also varies according to race and ethnicity and whether outcomes are affected. Methods We analyzed discharge abstracts from all nonfederal hospitals in California of patients hospitalized for a primary diagnosis of ventricular tachycardia or ventricular fibrillation between 1992 and 1994. We compared mortality rates and use of electrophysiologic study (EPS) and implantable cardioverter-defibrillator (ICD) procedures according to the race and ethnicity of the patient. Results Among 8713 patients admitted with ventricular tachycardia or ventricular fibrillation, 29% (n = 2508) had a subsequent EPS procedure, and 9% (n = 818) had an ICD implanted. After controlling for potential confounding factors, we found that black patients were significantly less likely than white patients to undergo EPS (odds ratio 0.72, CI 0.56-0.92) or ICD implantation (odds ratio 0.39, CI 0.25-0.60). Blacks discharged alive from the initial hospital admission had higher mortality rates over the next year than white patients, even after controlling for multiple confounding risk factors (risk ratio 1.18, CI 1.03-1.36). The use of EPS and ICD procedures was also significantly affected by several other factors, most notably by on-site procedure availability but also by age, sex, and insurance status. Conclusions In a large population of patients hospitalized for ventricular arrhythmia, blacks had significantly lower rates of utilization for EPS and ICD procedures and higher subsequent mortality rates. (Am Heart J 2002;144:431-9.)

Purpose The implantable cardioverter defibrillator has been assessed in randomized trials, but the generalizability of trial results to broader clinical settings is unclear. Our purpose was to evaluate the outcomes and costs of defibrillator use in an unselected population. Subjects and methods We identified 125,892 Medicare patients who were discharged between 1987 and 1995 after hospitalization with a primary diagnosis of ventricular tachycardia or ventricular fibrillation, 7789 of whom (6.2%) received a defibrillator. We used a multivariable propensity score that included patient and hospital characteristics to match pairs of patients, in which one patient received a defibrillator and the other did not. We compared mortality and costs in these 7612 matched pairs during 8 years of follow-up. Results Patients who received a defibrillator were more likely to be younger, white, male, and urban dwelling, and to have ischemic heart disease, heart failure, or a history of ventricular fibrillation. In the matched-pairs analysis, those who received a defibrillator had significantly lower mortality: 11% versus 19% at 1 year (odds ratio [OR] = 0.57; 95% confidence interval [CI]: 0.51 to 0.63), 20% versus 30% at 2 years (OR = 0.66; 95% CI: 0.60 to 0.72), and 28% versus 39% at 3 years (OR = 0.70; 95% CI: 0.63 to 0.77). These patients also had lower mortality at 8 years ( P = 0.0001), although this advantage over patients who received medical treatment only decreased over time. Expenditures among defibrillator recipients were consistently higher, with a cost-effectiveness ratio of $78,400 per life-year gained. Conclusion The use of implantable defibrillators was associated with significantly lower mortality and higher costs, whereas the cost-effectiveness was higher than many, but not all, generally accepted therapies.

10574 Background: There is growing evidence that adult oncology patients who know they are dying choose less intense care. Further, high intensity care is associated with worse caregiver outcomes. Little is known about pediatric oncology end-of-life care intensity. Methods: Using the California Office of Statewide Health Planning and Development administrative database linked to death certificates, we performed a retrospective population based analysis of cancer patients aged 0-21 who died between 2000 and 2011. The frequency of previously defined end-of-life intensity markers (hospital death, intense medical interventions, IV chemotherapy, and gastrostomy and tracheostomy tube placement) were calculated and multivariable logistic regression was used to determine clinical and sociodemographic factors associated with > 2 intensity markers (as above), intense medical intervention (cardiopulmonary resuscitation, intubation, ICU admission, or hemodialysis), and hospital death. Results: The 3,732 pediatric cancer decedents were 34% non-Hispanic whites and 45% Hispanic; 41% had hematologic malignancies and 59% solid tumors. The most prevalent intensity markers included: hospital death (63%) and ICU admission (20%). 65% had > 1 intensity marker, 23% > 2, and 22% > 1 intense medical intervention. There was a bimodal association between age and intensity: the youngest patients (age < 5) and adolescent patients (age 15-21) were more likely to receive intense care: < 5y (intense medical intervention: OR = 1.42; 95% CI, 1.1-1.9; hospital death: OR = 1.72; 95% CI, 1.4-2.2; > 2 markers: OR = 1.37, 95% CI 1.1-1.8); 15-21y (intense medical: OR = 1.48; 95% CI, 1.2-1.9; hospital death: OR = 1.39; 95% CI, 1.1-1.7; > 2 markers: OR = 1.35, 1.1-1.7) (references: 5-9y). Other factors associated with intensity included, hematologic malignancies, minority status, and death between 2008 and 2011 vs. < 2008. Conclusions: Nearly two-thirds of the pediatric cancer decedents had ≥1 marker of intense care and disparities exist. Patients < 5 and adolescents were more likely to receive intense end-of-life care. Further research needs to determine if these rates and variation are consistent with patient goals and factors associated with goal concurrent care.

6561 Background: Private health insurance is associated with improved outcomes in cancer patients. We know little, however, about the impact of the ACA-DCE, which extended private insurance to young adults (up to age 26) beginning in 2010, on the insurance status of young adults with cancer. This study sought to determine the effect of the ACA-DCE on having private insurance coverage among hospitalized young adult oncology patients. Methods: We performed a retrospective, population-based analysis of hospitalized young adult oncology patients (22-30 years-old) in California during 2006-2014 (n = 11,062) using the Office of Statewide Health Planning and Development database. Multivariable regression analyses examined the social and clinical predictors of having private insurance. Results are presented as adjusted odds ratios (OR) and 95% confidence intervals (CIs). A difference-in-difference analysis examined the influence of the ACA-DCE on insurance coverage by race/ethnicity and zip code federal poverty level. Results: Multivariable regression demonstrated patients of black and Hispanic race/ethnicity were less likely to have private insurance both before and after the ACA-DCE, compared to non-Hispanic white patients. Younger age (22-25 years) was associated with having private insurance after the ACA-DCE implementation (OR 1.18, CI 1.05-1.33; reference, 27-30 years). In the difference-in-difference analysis, private insurance increased among non-Hispanic whites aged 22-25 living in medium- (2006-2009: 64.6% versus (vs) 2011-2014: 69.1%; p = 0.003) and high-income zip codes (80.4% vs 82%; p = 0.043) and among Asian patients aged 22-25 living in high-income zip codes (73.2 vs 85.7%; p = 0.022). Private insurance decreased for all Hispanic patients aged 22-25 between the two time periods. Conclusions: The ACA-DCE provision was an important first step in increasing coverage, but it was not universal and generated disparity in coverage as gains occurred for non-Hispanic white and Asian patients living in higher income zip codes. This policy change was shown to increase coverage for a traditionally underinsured population and attention should now focus on those remaining uninsured.

The Agency for Healthcare Research and Quality Patient Safety Indicators (PSIs) do not capture complications arising after discharge. This study sought to quantify the bias related to omission of readmissions for PSI-qualifying conditions. Using 2000-2009 California Office of Statewide Health Planning and Development Patient Discharge Data, the study team examined the change in PSI rates when including readmissions in the numerator, hospitals performing in the extreme deciles, and longitudinal performance. Including 7-day readmissions resulted in a 0.3% to 8.9% increase in average hospital PSI rates. Hospital PSI rates with and without PSI-qualifying 30-day readmissions were highly correlated for point estimates and within-hospital longitudinal change. Most hospitals remained in the same relative performance decile. Longer length of stay, public payer, and discharge to skilled nursing facilities were associated with a higher risk of readmission for a PSI-qualifying event. Failure to include readmissions in calculating PSIs is unlikely to lead to erroneous conclusions.

132 Background: Cancer is the leading cause of non-accidental death amongst adolescents and young adults (AYA), aged 15-39, in the U.S. It is critical to understand end of life (EOL) care of AYA cancer decedents, including use of medically intense interventions like intubation. Although desired by some, most patients prefer a natural death. We sought to determine rates of medically intense interventions at end of life for AYA cancer decedents and associated factors. Methods: Using the California Office of Statewide Health Planning and Development private administrative database linked to death certificates, we performed a retrospective population based analysis of patients aged 15-39 with cancer who died between 2000-2010. We used previously defined administrative codes indicative of intense EOL care: intubation, CPR, hospital re-admission, and ICU admission in the last 30 days of life, and location of death. The frequencies of each intense item were calculated and multivariate logistic regression was used to determine clinical (including treatment at specialty center vs non) and socio-demographic factors associated with each item and receipt of ≥ 2 items. Results: The 8,978 AYA cancer decedents were 46% non-Hispanic white, 29% Hispanic, 10% non-Hispanic black, 11% Asian; 21% had hematologic malignancies, 70% had solid tumors, and 9% had secondary neoplasms; 58% were hospitalized only at non-specialty centers in the last 6 months of life. 62% received ≥ 1 medically intense EOL care intervention, and 32% received > 2. Factors associated with > 2 intense EOL care interventions were: non-Hispanic black (OR 1.38, 95% CI 1.16-1.65), Hispanics (1.19, 1.06-1.35), Asians (1.30, 1.10-1.52); those sometimes (2.19, 1.87-2.56) or never (1.44, 1.26-1.65) seen at specialty centers; hematologic malignancies (1.77, 1.57-2.00 ref grp: solid tumors) whereas secondary malignancies were not associated with > 2 intense markers (0.68, 0.56-0.83). Conclusions: Nearly two-thirds of the AYA cancer decedents received medically intense EOL interventions and disparities exist in receipt of such care. Further research needs to determine if the disparities are due to healthcare system, patient preference, or other factors.

126 Background: Cancer is the leading cause of non-accidental death among adolescents and young adults (AYA) in the US. The last year of life involves significant inpatient resources for older patients. We sought to determine the quantity and pattern of inpatient care for AYA cancer decedents in the last year of life to learn their healthcare system impact and groups to target for intervention. Methods: Using the California Office of Statewide Health Planning and Development private administrative database linked to death certificates, we performed a retrospective cross-sectional population-based analysis of patients aged 15-39 with cancer who died between 2000-2011. We calculated the number of admissions, hospital days, and percent of the cohort admitted each day in the last year of life. We determined the bed-day distribution across the population and the clinical and socio-demographic factors associated with high inpatient utilization. Results: The 9562 AYA cancer decedents were 45% non-Hispanic white, 30% Hispanic; 20% had hematologic malignancies, 70% had solid tumors. They were hospitalized, on average, 4.3 times and 40.6 days in the last year of life, increasing 3 months before death. Bed day occupation was skewed: 5% of the patients occupied 20% of the bed days and 18% occupied 50%. Factors associated with increased odds of being a top 5% utilizer were being Hispanic (OR: 1.48, 95% CI: 1.15-1.90, ref: non-Hispanic white), and having Acute Myelogenous Leukemia (AML) (2.7, 1.74-0.67, ref: Acute Lymphoblastic Leukemia (ALL). Factors associated with decreased odds were rural residence (0.39, 0.23-0.67, ref: urban), HMO insurance (0.58, 0.38-0.88, ref: private non-HMO), no hospitalizations at specialty centers (0.72, 0.53-0.97, ref: specialty center only), and having lymphoma or a solid tumor (ORs 0.035-0.39, CI range 0.005-0.56, ref: ALL). Conclusions: AYAs dying of cancer spent 40.6 days in the hospital in their last year of life (more than 1 in 9 days) with higher rates for Hispanics, AML patients, those with urban residence, and those hospitalized at specialty centers. Further research needs to determine what is driving these patterns, if they are preventable, and if they align with patient and family wishes.

e18020Background: AYAs with cancer have had less improvement in survival compared to their younger counterparts. This may be partly due to differential access to specialized cancer centers (SCC), a...

A large-scale review is needed to characterize the rates of airway, respiratory, and cardiovascular complications after pediatric tonsillectomy and adenoidectomy (TA) for inpatient and ambulatory cohorts.To identify risk factors for postoperative complications stratified by age and operative facility type among children undergoing TA.This retrospective review included 115,214 children undergoing TA in hospitals, hospital-based facilities (HBF), and free-standing facilities (FSF) in California from January 1, 2005, to December 31, 2010. The analysis used the State of California Office of Statewide Health Planning and Development private inpatient data and Emergency Department and Ambulatory Surgery public data. Inpatient (n = 18,622) and ambulatory (n = 96,592) cohorts were identified by codes from the International Classification of Diseases, Ninth Revision, and Current Procedural Terminology. Data were collected from September 2011 to March 2012 and analyzed from March through May 2012.Rates of airway, respiratory, and cardiovascular complications.A total of 18,622 inpatients (51% male; 49% female; mean age, 5.4 [range, 0-17] years) and 96,592 ambulatory patients (37% male; 35% female; 28%, masked; mean age, 7.6 [range, 0-17] years) underwent analysis. The ratio of ambulatory to inpatient procedures was 5:1. Inpatients demonstrated more comorbidities (≤8, compared with ≤4 for HBF and ≤3 for FSF patients) and, in general, their complication rates were 2 to 5 times higher (seen in 1% to 12% of patients) than those in HBFs (0.2% to 5%), and more than 10 times higher than those in the FSFs (0% to 0.38%), with rates varying markedly by age range and facility type. Tonsillectomy and adenoidectomy was associated with increased risk for all complication types in both settings, reaching an odds ratio of 8.5 (95% CI, 6.6-11.1) for respiratory complications in the ambulatory setting. Inpatients aged 0 to 9 years experienced higher rates of airway and respiratory complications, peaking at an odds ratio of 7.5 (95% CI, 3.1-18.2) for airway complications in the group aged 0 to 11 months.Large numbers of pediatric patients undergo TA in ambulatory settings despite higher rates of complications in younger patients and patients with more comorbidities. Fortunately, a high percentage of these patients has been appropriately triaged to the inpatient setting. Further research is needed to elucidate the subgroups that warrant postoperative hospitalization.

Background Previous research has provided evidence that socioeconomic status has an impact on invasive treatments use after acute myocardial infarction. In this paper, we compare the socioeconomic inequality in the use of high-technology diagnosis and treatment after acute myocardial infarction between the US, Quebec and Belgium paying special attention to financial incentives and regulations as explanatory factors. Methods We examined hospital-discharge abstracts for all patients older than 65 who were admitted to hospitals during the 1993–1998 period in the US, Quebec and Belgium with a primary diagnosis of acute myocardial infarction. Patients' income data were imputed from the median incomes of their residential area. For each country, we compared the risk-adjusted probability of undergoing each procedure between socioeconomic categories measured by the patient's area median income. Results Our findings indicate that income-related inequality exists in the use of high-technology treatment and diagnosis techniques that is not justified by differences in patients' health characteristics. Those inequalities are largely explained, in the US and Quebec, by inequalities in distances to hospitals with on-site cardiac facilities. However, in both Belgium and the US, inequalities persist among patients admitted to hospitals with on-site cardiac facilities, rejecting the hospital location effect as the single explanation for inequalities. Meanwhile, inequality levels diverge across countries (higher in the US and in Belgium, extremely low in Quebec). Conclusion The findings support the hypothesis that income-related inequality in treatment for AMI exists and is likely to be affected by a country's system of health care.
