The state of point-of-care ultrasound training in pediatric anesthesia fellowship programs in the United States: A survey assessment.

BACKGROUND: Point-of-care ultrasound is an invaluable bedside tool for anesthesiologists and has been integrated into anesthesiology residency training and board certification in the United States. Little is known about point-of-care ultrasound training practices in pediatric anesthesia fellowship programs. AIMS: To describe the current state of point-of-care ultrasound education in pediatric anesthesia fellowship programs in the United States. METHODS: We conducted a cross-sectional survey study distributed to 60 American Accreditation Council for Graduate Medical Education-accredited pediatric anesthesia fellowship programs. Two programs were in their initial accreditation period and were excluded due to lack of historical data. Program directors or associate program directors were invited to complete this 23-item survey. RESULTS: Thirty-three of fifty-eight programs (57%) completed the survey. Of those, 15 programs (45%) reported having a point-of-care ultrasound curriculum. Programs with ≤3 fellows per year were less likely to have an ultrasound curriculum compared to programs with ≥4 fellows per year (30% programs 0-3 fellows/year vs. 69% programs ≥4 fellows/year, odds ratio 0.19 [95% confidence intervals 0.04-0.87]; p = .03). Program directors and associate program directors rated point-of-care ultrasound training as highly valuable to fellows' education. Barriers to use most commonly included lack of experience (64%), lack of oversight/interpretive guidance (58%), and lack of time (45%). Programs without point-of-care ultrasound training had significantly higher odds of listing lack of ultrasound access as a primary barrier (50% programs without vs. 13% programs with, odds ratio 6.5, [95% confidence intervals 1.3-50]; p = .04). CONCLUSIONS: This observational survey-based study suggests that fewer than half of pediatric anesthesia training programs in the United States offer point-of-care ultrasound education. Additional research is needed to optimize this education and training in pediatric anesthesia fellowship programs.

A Pediatric Interprofessional Cardiac Intensive Care Unit Intervention: CICU Teams and Loved Ones Communicating (CICU TALC) is Feasible, Acceptable, and Improves Clinician Communication Behaviors in Family Meetings.

Parents of children in the pediatric cardiac intensive care unit (CICU) are often unprepared for family meetings (FM). Clinicians often do not follow best practices for communicating with families, adding to distress. An interprofessional team intervention for FM is feasible, acceptable, and positively impacts family preparation and conduct of FM in the CICU. We implemented a family- and team-support intervention for conducting FM and conducted a pretest-posttest study with parents of patients selected for a FM and clinicians. We measured feasibility, fidelity to intervention protocol, and parent acceptability via questionnaire and semi-structured interviews. Clinician behavior in meetings was assessed through semantic content analyses of meeting transcripts tracking elicitation of parental concerns, questions asked of parents, and responses to parental empathic opportunities. Logistic and ordinal logistic regression assessed intervention impact on clinician communication behaviors in meetings comparing pre- and post-intervention data. Sixty parents (95% of approached) were enrolled, with collection of 97% FM and 98% questionnaire data. We accomplished > 85% fidelity to intervention protocol. Most parents (80%) said the preparation worksheet had the right amount of information and felt positive about families receiving this worksheet. Clinicians were more likely to elicit parental concerns (adjusted odds ratio = 3.42; 95%CI [1.13, 11.0]) in post-intervention FM. There were no significant differences in remaining measures. Implementing an interprofessional team intervention to improve family preparation and conduct of FM is locally feasible, acceptable, and changes clinician behaviors. Future research should assess broader impact of training on clinicians, patients, and families.

Status 1B designation does not adequately prioritize children with acute-on-chronic liver failure for liver transplantation.

Acute-on-chronic liver failure (ACLF) is an acute decompensation of chronic liver disease leading to multiorgan failure and mortality. The objective of this study was to evaluate characteristics and outcomes of children with ACLF who are at the highest priority for liver transplantation (LT) on the United Network for Organ Sharing (UNOS) database-listed as status 1B. The characteristics and outcomes of 478 children with ACLF listed as status 1B on the UNOS LT waiting list from 2007-2019 were compared with children with similar or higher priority listing for transplant: 929 with acute liver failure (ALF) listed as status 1A and 808 with metabolic diseases and malignancies listed as status 1B (termed "non-ACLF"). Children with ACLF had comparable rates of cumulative organ failures compared with ALF (45% vs. 44%; p > 0.99) listings, but higher than non-ACLF (45% vs. 1%; p < 0.001). ACLF had the lowest LT rate (79%, 84%, 95%; p < 0.001), highest pre-LT mortality (20%, 11%, 1%; p < 0.001), and longest waitlist time (57, 3, 56 days; p < 0.001), and none recovered without LT (0%, 4%, 1%; p < 0.001). In survival analyses, ACLF was associated with an increased adjusted hazard ratio (HR) for post-LT mortality (HR, 1.50 vs. ALF [95% confidence interval, CI, 1.02-2.19; p = 0.04] and HR, 1.64 vs. non-ACLF [95% CI, 1.15-2.34; p = 0.01]). ACLF has the least favorable waitlist and post-LT outcomes of all patients who are status 1A/1B. Increased prioritization on the LT waiting list may offer children with ACLF an opportunity for enhanced outcomes.

Tailored medication adherence incentives for high-risk children with asthma: a pilot study.

Objective: While reminder-based electronic monitoring systems have shown promise in enhancing inhaled corticosteroid (ICS) adherence in select populations, more engaging strategies may be needed in families of children with high-risk asthma. This study assesses the acceptability and feasibility of gain-framed ICS adherence incentives in families of urban, minority children with frequent asthma hospitalization.Methods: We enrolled children aged 5-11 years with multiple yearly asthma hospitalizations in a 2-month, mixed methods, ICS adherence incentive pilot study. All participants received inhaler sensors and a smartphone app to track ICS use. During month 1, families received daily adherence reminders and weekly feedback, and children earned up to $1/day for complete adherence. No reminders, feedback, or incentives were provided in month 2. We assessed feasibility and acceptability using caregiver surveys and semi-structured interviews and ICS adherence using electronic monitoring data.Results: Of the 29 families approached, 20 enrolled (69%). Participants were primarily Black (95%), publicly insured (75%), and averaged 2.9 asthma hospitalizations in the prior year. Fifteen of the 16 caregivers (94%) surveyed at month 2 liked the idea of receiving adherence incentives. Mean adherence was significantly higher in month 1 compared with month 2 (80% vs. 33%, mean difference = 47%; 95% CI [33, 61], p < 0.001). Caregivers reported that their competing priorities often limited adherence, while incentives helped motivate child adherence.Conclusions: ICS adherence incentives were acceptable and feasible in a high-risk cohort of children with asthma. Future studies should assess the efficacy of adherence incentives in enhancing ICS adherence in high-risk children.

Pulse Oximetry Screening Has Not Changed Timing of Diagnosis or Mortality of Critical Congenital Heart Disease.

This study evaluates the effectiveness of mandatory pulse oximetry screening. The objective is to evaluate whether mandatory pulse oximetry testing had decreased the late critical congenital heart disease (CCHD) diagnosis rate and reduced mortality in neonatal subjects. This was a single center, retrospective cohort study comparing the timing of diagnosis of CCHD between neonates undergoing cardiac surgery in 2009-2010, prior to mandatory pulse oximetry screening, and neonates in 2015-2016, after mandatory pulse oximetry screening was instituted. Follow-up was for 1 year. We defined CCHD as lesions requiring surgical correction within 30 days of life. Exclusions included: pacemaker insertions, vascular ring divisions, closure of patent ductus arteriosus, arterial cutdown, or extracorporeal membrane oxygenation cannulation without structural heart disease as the sole procedure, or if subjects were born at home. Infants diagnosed prior to discharge from birth hospital were defined as early postnatal; late postnatal subjects were diagnosed after birth hospital discharge. In-hospital mortality and 1-year mortality were measured. A total of 527 neonates were included; 251 (47.6%) comprised the pre-mandatory pulse oximetry screening cohort (2009-2010). Only 3.6% of the 2009-2010 cohort and 4.3% of the 2015-2016 cohort were diagnosed late (p = 0.66). One-year mortality decreased during the study period (17.2% in 2009-2010 vs 10.5% in 2015-2016, p = 0.03). There were no deaths in the late CCHD diagnosis groups. Mandatory pulse oximetry screening legislation has not changed the late postnatal diagnosis rate at our institution. Mortality for neonatal CCHD has declined, but this decline is not attributable to mandatory pulse oximetry screening.

Controller adherence following hospital discharge in high risk children: A pilot randomized trial of text message reminders.

OBJECTIVE: To assess the feasibility of a mobile health, inhaled corticosteroid (ICS) adherence reminder intervention and to characterize adherence trajectories immediately following severe asthma exacerbation in high-risk urban children with persistent asthma. METHODS: Children aged 2-13 with persistent asthma were enrolled in this pilot randomized controlled trial during an asthma emergency department (ED) visit or hospitalization. Intervention arm participants received daily text message reminders for 30 days, and both arms received electronic sensors to measure ICS use. Primary outcomes were feasibility of sensor use and text message acceptability. Secondary outcomes included adherence to prescribed ICS regimen and 30-day adherence trajectories. Group-based trajectory modeling was used to examine adherence trajectories. RESULTS: Forty-one participants (mean age 5.9) were randomized to intervention (n = 21) or control (n = 20). Overall, 85% were Black, 88% had public insurance, and 51% of the caregivers had a high school education or less. Thirty-two participant families (78%) transmitted medication adherence data; of caregivers who completed the acceptability survey, 25 (96%) chose to receive daily reminders beyond that study interval. Secondary outcome analyses demonstrated similar average daily adherence between groups (intervention = 36%; control = 32%, P = 0.73). Three adherence trajectories were identified with none ever exceeding 80% adherence. CONCLUSIONS: Within a high-risk pediatric cohort, electronic monitoring of ICS use and adherence reminders delivered via text message were feasible for most participants, but there was no signal of effect. Adherence trajectories following severe exacerbation were suboptimal, demonstrating an important opportunity for asthma care improvement.

Risk of brain metastases in patients with nonmetastatic lung cancer: Analysis of the Metropolitan Detroit Surveillance, Epidemiology, and End Results (SEER) data.

BACKGROUND: Brain metastases (BM) remain an important cause of morbidity and mortality in patients with lung cancer. The current study evaluated population-based incidence and outcomes of BM in patients with nonmetastatic lung cancer. METHODS: Patients diagnosed with nonmetastatic first primary lung cancer between 1973 and 2011 in the Metropolitan Detroit Surveillance, Epidemiology, and End Results (SEER) registry were used for the current analysis. Age-adjusted odds ratios of developing BM based on various demographic characteristics and histology were calculated with 95% confidence intervals. Adjusted Cox proportional hazard ratios and log-rank tests of Kaplan-Meier survival curves were calculated to evaluate survival differences for non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). RESULTS: The incidence of BM in patients with nonmetastatic NSCLC and SCLC was 9% and 18%, respectively. There was variation in the incidence of BM according to NCSLC histology. The incidence of BM was higher in patients aged <60 years for both NSCLC and SCLC, but there were no differences noted by race for either histological group. Female patients with NSCLC were more likely to have BM than male patients. There was variation in the proportion of BM in both patients with NSCLC and SCLC over the three 13-year periods of diagnosis. The risk of death (hazard ratio) was found to be significantly higher for patients with NSCLC with BM, but was not significantly higher in patients with SCLC with BM. CONCLUSIONS: The incidence of BM in patients with nonmetastatic lung cancer varies according to histology, age, and sex. BM are associated with worse survival for patients with NSCLC but not those with SCLC. Cancer 2016;122:1921-7. © 2016 American Cancer Society.

Home visiting and perinatal smoking: a mixed-methods exploration of cessation and harm reduction strategies.

BACKGROUND: Home visiting programs represent an important primary prevention strategy for adverse prenatal health behaviors; the various ways in which home visiting programs impact prenatal smoking cessation and reduction behaviors remain understudied. METHODS: Mixed methods approach using a retrospective cohort of propensity score matched home visiting clients and local-area comparison women with first births between 2008-2014 in a large Northeast state. Multivariable logistic and linear regression estimated third trimester prenatal tobacco smoking cessation and reduction. Additionally, qualitative interviews were conducted with 76 home visiting clients. RESULTS: A program effect was seen for smoking cessation such that clients who smoked less than ten cigarettes per day and those who smoked 20 or more cigarettes per day during the first trimester were more likely to achieve third trimester cessation than comparison women (p <0.01 and p = 0.01, respectively). Only for heavy smokers (20 or more cigarettes during the first trimester) was there a significant reduction in number of cigarettes smoked by the third trimester versus comparison women (p = 0.01). Clients expressed the difficulty of cessation, but addressed several harm-reduction strategies including reducing smoking in the house and wearing a smoking jacket. Clients also described smoking education that empowered them to ask others to not smoke or adopt other harm reducing behaviors when around their children. CONCLUSIONS: While a significant impact on smoking cessation was seen, this study finds a less-clear impact on smoking reduction among women in home visiting programs. As home visiting programs continue to expand, it will be important to best identify effective ways to support tobacco-related harm reduction within vulnerable families.

Identifying Suicide Risk in Adolescents With Firearm Access: Screening in the Emergency Department.

OBJECTIVE: This study compares current suicidal ideation, prior suicide attempt and associated self-reported risk factors in adolescents with and without access to firearms. METHODS: Using data from a clinically applied behavioral health assessment completed by adolescents presenting to a tertiary children's hospital emergency department (ED; N = 15,806), we evaluated the association between firearm access (ie, firearm in the home or ability to obtain one within 24 hours), each of the included suicide risk factors (ie, depressive symptoms, trauma victimization, bullying victimization), and our primary outcomes (ie, current suicidal ideation and prior suicide attempt). We performed regression analyses on 3 groups: 1) The overall population; 2) Only the participants with firearm access; and 3) Only the participants without firearm access. RESULTS: Fourteen percent (2179/15,806) of the sample reported a firearm in the home or ability to access one within 24 hours. Overall, 6.8% of participants reported current suicidal ideation and 9.1% reported prior suicide attempt. Youth with firearm access had 1.52 times higher odds of current suicidal ideation and 1.61 times higher odds of prior suicide attempt compared to youth without firearm access. All included suicide risk factors were found to significantly increase the odds of current suicidal ideation and prior suicide attempt in the overall sample; this increase was similar in the groups with and without firearm access. CONCLUSIONS: Adolescents with firearm access have higher odds of suicidal ideation and prior attempt compared to those without firearm access, highlighting the need for universal ED-based screening for suicidality and lethal means.

Trends in Ductus Arteriosus Stent Versus Blalock-Taussig-Thomas Shunt Use and Comparison of Cost, Length of Stay, and Short-Term Outcomes in Neonates With Ductal-Dependent Pulmonary Blood Flow: An Observational Study Using the Pediatric Health Information Systems Database.

BACKGROUND: The modified Blalock-Taussig-Thomas shunt is the gold standard palliation for securing pulmonary blood flow in infants with ductal-dependent pulmonary blood flow. Recently, the ductus arteriosus stent (DAS) has become a viable alternative. METHODS AND RESULTS: This was a retrospective multicenter study of neonates ≤30 days undergoing DAS or Blalock-Taussig-Thomas shunt placement between January 1, 2017 and December 31, 2020 at hospitals reporting to the Pediatric Health Information Systems database. We performed generalized linear mixed-effects modeling to evaluate trends in intervention and intercenter variation, propensity score adjustment and inverse probability weighting with linear mixed-effects modeling to analyze length of stay and cost of hospitalization, and generalized linear mixed modeling to analyze differences in 30-day outcomes. There were 1874 subjects (58% male, 61% White) from 45 centers (29% DAS). Odds of DAS increased with time (odds ratio [OR] 1.23, annually, P<0.01 [95% CI, 1.10-1.38]) with significant intercenter variation (median OR, 3.81 [95% CI, 2.74-5.91]). DAS was associated with shorter hospital length of stay (ratio of geometric means, 0.76 [95% CI, 0.63-0.91]), shorter intensive care unit length of stay (ratio of geometric means, 0.77 [95% CI, 0.61-0.97]), and less expensive hospitalization (ratio of geometric means, 0.70 [95% CI, 0.56-0.87]). Intervention was not significantly associated with odds of 30-day transplant-free survival (OR,1.18 [95% CI, 0.70-1.99]) or freedom from catheter reintervention (OR, 1.02 [95% CI, 0.65-1.58]), but DAS was associated with 30-day freedom from composite adverse outcome (OR, 1.51 [95% CI, 1.11-2.05]). CONCLUSIONS: Use of DAS is increasing, but there is variability across centers. Though odds of transplant-free survival and reintervention were not significantly different after DAS, and DAS was associated with shorter length of stay and lower in-hospital costs.

Pulmonary hypertension among children with in-hospital cardiac arrest: A multicenter study.

AIMS: To determine the prevalence of pulmonary hypertension (PH) among children with in-hospital cardiac arrest (IHCA) and its association with survival. METHODS: Children (<18 years) admitted to ICUs participating in the Virtual Pediatric Systems multicenter registry between January 2011 and December 2017 who had an IHCA during their hospitalization were included. Patients were classified by whether they had a documented diagnosis of PH at the time of IHCA. Clinical characteristics were compared between patients with and without PH. After propensity score matching, conditional logistic regression within the matched cohort determined the association between PH and survival to hospital discharge. RESULTS: Of 18,575 children with IHCA during the study period, 1,590 (8.6%) had a pre-arrest diagnosis of PH. Patients with PH were more likely to be 29 days to 2 years of age, female, Black/African American, and American Indian/Alaskan Native, and to be treated in a cardiac ICU or mixed PICU/cardiac ICU. At ICU admission, PH patients had a lower probability of death as determined by the Pediatric Index of Mortality 2 (PIM-2) score. Patients with PH were more likely to be receiving inhaled nitric oxide (13.0% vs. 2.1%; p < 0.001). Propensity score matching successfully matched 1,302 PH patients with 3,604 non-PH patients. Patients with PH were less likely to survive to hospital discharge (aOR 0.83; 95% CI: 0.72-0.95; p = 0.01) than non-PH patients. CONCLUSIONS: In this large multicenter study, 8.6% of children with IHCA had pre-existing documented PH. These children were less likely to survive to hospital discharge than those without PH.

Intrapartum group B Streptococcal prophylaxis and childhood weight gain.

OBJECTIVE: To determine the difference in rate of weight gain from birth to 5 years based on exposure to maternal group B streptococcal (GBS) intrapartum antibiotic prophylaxis (IAP). DESIGN: Retrospective cohort study of 13 804 infants. SETTING: Two perinatal centres and a primary paediatric care network in Philadelphia. PARTICIPANTS: Term infants born 2007-2012, followed longitudinally from birth to 5 years of age. EXPOSURES: GBS IAP defined as penicillin, ampicillin, cefazolin, clindamycin or vancomycin administered ≥4 hours prior to delivery to the mother. Reference infants were defined as born to mothers without (vaginal delivery) or with other (caesarean delivery) intrapartum antibiotic exposure. OUTCOMES: Difference in rate of weight change from birth to 5 years was assessed using longitudinal rate regression. Analysis was a priori stratified by delivery mode and adjusted for relevant covariates. RESULTS: GBS IAP was administered to mothers of 2444/13 804 (17.7%) children. GBS IAP-exposed children had a significantly elevated rate of weight gain in the first 5 years among vaginally-born (adjusted rate difference 1.44% (95% CI 0.3% to 2.6%)) and caesarean-born (3.52% (95% CI 1.9% to 5.2%)) children. At 5 years, the rate differences equated to an additional 0.24 kg among vaginally-born children and 0.60 kg among caesarean-born children. CONCLUSION: GBS-specific IAP was associated with a modest increase in rate of early childhood weight gain. GBS IAP is an effective intervention to prevent perinatal GBS disease-associated morbidity and mortality. However, these findings highlight the need to better understand effects of intrapartum antibiotic exposure on childhood growth and support efforts to develop alternate prevention strategies.

Intrapartum Group B Streptococcal Prophylaxis and Childhood Allergic Disorders.

OBJECTIVES: To determine if maternal intrapartum group B Streptococcus (GBS) antibiotic prophylaxis is associated with increased risk of childhood asthma, eczema, food allergy, or allergic rhinitis. METHODS: Retrospective cohort study of 14 046 children. GBS prophylaxis was defined as administration of intravenous penicillin, ampicillin, cefazolin, clindamycin, or vancomycin to the mother, ≥4 hours before delivery. Composite primary outcome was asthma, eczema, or food allergy diagnosis within 5 years of age, identified by diagnosis codes and appropriate medication prescription. Allergic rhinitis was defined by using diagnostic codes only and analyzed as a separate outcome. Analysis was a priori stratified by delivery mode and conducted by using Cox proportional hazards model adjusted for multiple confounders and covariates. Secondary analyses, restricted to children retained in cohort at 5 years' age, were conducted by using multivariate logistic regression. RESULTS: GBS prophylaxis was not associated with increased incidence of composite outcome among infants delivered vaginally (hazard ratio: 1.13, 95% confidence interval [CI]: 0.95-1.33) or by cesarean delivery (hazard ratio: 1.08, 95% CI: 0.88-1.32). At 5 years of age, among 10 404 children retained in the study, GBS prophylaxis was not associated with the composite outcome in vaginal (odds ratio: 1.21, 95% CI: 0.96-1.52) or cesarean delivery (odds ratio: 1.17, 95% CI: 0.88-1.56) cohorts. Outcomes of asthma, eczema, food allergy, separately, and allergic rhinitis were also not associated with GBS prophylaxis. CONCLUSIONS: Intrapartum GBS prophylaxis was not associated with subsequent diagnosis of asthma, eczema, food allergy, or allergic rhinitis in the first 5 years of age.

Resource Use and Outcomes of Pediatric Congenital Heart Disease Admissions: 2003 to 2016.

Background Children with congenital heart disease (CHD) are known to consume a disproportionate share of resources, yet there are limited data concerning trends in resource use and mortality among admitted children with CHD. We hypothesize that charges in CHD-related admissions increased but that mortality improved over time. Methods and Results This study, including patients <18 years old with CHD, examined inpatient admissions from the nationally representative Kids' Inpatient Database from 2003 to 2016 in order to assess the frequency, medical complexity, and outcomes of CHD hospital admissions. A total of 859 843 admissions of children with CHD were identified. CHD admissions increased by 31.8% from 2003 to 2016, whereas overall pediatric admissions decreased by 13.4%. Compared with non-CHD admissions, those with CHD were more likely to be <1 year of age (80.5% versus 63.3%), and to have ≥1 complex chronic condition (39.7% versus 9.3%). For CHD admissions, mortality was higher (2.97% versus 0.31%) and adjusted median charges greater ($48 426 [interquartile range (IQR), $11.932-$161 048] versus $4697 [IQR, $2551-$12 301]) (P<0.0001 for all). Among CHD admissions, whereas adjusted median charges increased from $35 577 (IQR, $9303-$110 439) to $61 696 (IQR, $15 212-$219 237), mortality decreased from 3.2% to 2.7% (P for trend <0.0001). CHD admissions accounted for an increased proportion of all inpatient deaths, from 18.0% in 2003 to 24.5% in 2016. Conclusions Children admitted with CHD are 10 times more likely to die than those without CHD and have higher charges. Although the rate of mortality in CHD admissions decreased, children with CHD accounted for an increasing proportion of all pediatric inpatient deaths. Effective resource allocation is critical to optimize outcomes in these high-risk patients.

Disparities in Care: Do Children with Autism Spectrum Disorder Experience Differential Medication Receipt In The Emergency Department?

OBJECTIVE: The primary objective of this study was to describe analgesia administration between neurotypical (NT) individuals and those with autism spectrum disorder (ASD) diagnosed with appendicitis or long bone fractures in the emergency department (ED). A secondary objective was to compare the rates of complicated appendicitis as a proxy for delayed diagnosis between the groups. METHODS: This is a retrospective cohort study using the Pediatric Health Information System database. Study participants were children aged 6 to 18 years with ASD and with an ED visit for appendicitis or fracture between 2004 and 2015 who were matched to demographically similar NT children. Children with a developmental disorder and/or complex chronic condition were excluded. Coarsened exact matching and logistic regression were used to investigate the association between ASD status and opioid and non-opioid medication receipt. Comparison of the rates of complicated appendicitis in children with ASD and NT children was conducted before matching. RESULTS: From 2004 to 2015, 126,412 children with appendicitis and 392,151 children with long bone fractures were identified. Of these, 889 children had a diagnosis of ASD and were matched to 35,672 NT controls with appendicitis. In addition, 2117 children with ASD were matched to 200,635 NT controls with long bone fractures. Receipt of opioids or nonsteroidal anti-inflammatory drugs was not found to be significantly different between the 2 groups. However, a larger proportion of children with ASD presented with complicated appendicitis compared with NT controls (37.1% vs 29.9%, respectively; p < 0.001). CONCLUSION: Receipt of analgesia did not differ significantly between populations of ASD and NT peers. Children with ASD have increased rates of complex appendicitis, possibly suggesting limited access to care or provider difficulty in evaluating this patient population.

Modern Radiation Further Improves Survival in Non-Small Cell Lung Cancer: An Analysis of 288,670 Patients.

Background: Radiation therapy plays an increasingly important role in the treatment of patients with non-small-cell lung cancer (NSCLC). The purpose of the present study is to assess the survival outcomes of radiotherapy treatment compared to other treatment modalities and to determine the potential role of advanced technologies in radiotherapy on improving survival. Methods: We used cancer incidence and survival data from the Surveillance, Epidemiology, and End Results database linked to U.S. Census data to compare survival outcomes of 288,670 patients with stage I-IV NSCLC treated between 1999 and 2008. The primary endpoint was overall survival. Results: Among the 288,670 patients diagnosed with stage I-IV NSCLC, 92,374 (32%) patients received radiotherapy-almost double the number receiving surgery (51,961, 18%). Compared to other treatment groups and across all stages of NSCLC, patients treated with radiotherapy showed greater median and overall survival than patients without radiation treatment (p < 0.0001). Radiotherapy had effectively improved overall survival regardless of age, gender, and histological categorization. Radiotherapy treatment received during the recent time period 2004 - 2008 is correlated with enhanced survival compared to the earlier time period 1999 - 2003. Conclusion: Radiation therapy was correlated with increased overall survival for all patients with primary NSCLC across stages. Combined surgery and radiotherapy treatment also correlates with improved survival, signaling the value of bimodal or multimodal treatments. Population-based increases in overall survival were seen in the recent time period, suggesting the potential role of advanced radiotherapeutic technologies in enhancing survival outcomes for lung cancer patients.

The effect of targeted therapy on overall survival in advanced renal cancer: a study of the national surveillance epidemiology and end results registry database.

INTRODUCTION: With the advent and availability of targeted therapy, the treatment of advanced/metastatic renal cell carcinoma (RCC) underwent a drastic change in 2005. The effect of this change on clinical outcome within the population has not been studied. The aim of this study was to evaluate the overall survival (OS), before, and after availability of targeted therapy, for advanced RCC cases in the population-based Surveillance, Epidemiology, and End Results (SEER) cancer registry. MATERIALS AND METHODS: All advanced (regional and distant stage) RCC cases diagnosed within the 2000 to 2008 time periods were included. Because SEER does not report the exact therapy, and because targeted therapy was initially approved in 2005, we evaluated and compared the OS outcomes of advanced RCC cases diagnosed between the years 2000 and 2003 (before targeted therapy era) with that of those diagnosed between 2005 and 2008 (targeted therapy era). RESULTS: There was a significant improvement in OS for advanced RCC patients treated in the targeted therapy era (n = 12,330) compared with those treated in the era before targeted therapy (n =11,565) (median OS 20 months vs. 15 months, P = .0006). Multivariate analysis revealed that in the time period before targeted therapy, age older than 65 years, black race, and lack of nephrectomy were predictors of a shorter OS. CONCLUSION: In univariate and multivariate analysis, targeted therapy demonstrated improvement in OS. Increasing access to targeted therapies is likely to improve outcomes in advanced RCC.

Persistent socioeconomic inequalities in cancer survival in the United States: 1973-2007 surveillance, epidemiology and end results (SEER) data for breast cancer and non-Hodgkin's lymphoma.

PURPOSE: Census tract variables have not been widely available for SEER-wide data due to several technical reasons; thus, prior studies have been conducted on a specific-community basis only or used county-level data. This study is the first to evaluate long-term chronological trends in cancer survival by selected socioeconomic variables of census tract level based on multiple SEER registry data. METHODS: 177,128 breast cancer and 45,615 non-Hodgkin's lymphoma (NHL) cases diagnosed from 1973-2007 and followed through 2009 from 4 SEER registries (Detroit, Hawaii, Utah and Seattle-Puget Sound), were linked to decennial census tract data (1970-2000). Five-year relative survival was calculated using the lifetable method according to census tract poverty levels and by year of diagnosis. The Cox proportional hazard model was used to estimate hazard ratios (HR) for death in 5 years from diagnosis, adjusted for selected covariates and SEER historical stage in the limited models only. RESULTS: Although the 5-year relative survival from both cancers improved similarly across poverty levels as percent per year, absolute increase per year was greater for lower poverty neighborhoods. This trend was most consistently observed for distant stage of cancer. The multivariable HR were significantly higher in the highest poverty group (greater than 20%), 1.41 and 1.33, for breast cancer and NHL respectively, than the lowest (greater than or equal to 5%). Additional adjustment for stage at diagnosis reduced the HR in the highest poverty level in breast cancer patients to 1.30, but had minimal effect on NHL. Socioeconomic disparities in overall survival were more evident in neighborhoods with higher proportions of racial minorities and in middle-aged patients than younger or older patients. CONCLUSIONS: Relative survival for both types of cancer improved over last 35-year period across poverty levels, but absolute differences increased. More studies are needed to develop innovative community-level interventions.
