Using behavioral theory to understand partisan differences in COVID-19 vaccination and booster intentions.

In 2020, the Food and Drug Administration granted emergency use authorization for two COVID-19 vaccines. Two years later, the Centers for Disease Control and Prevention estimated that more than 250 million individuals had received at least one dose of the vaccine. Despite the large numbers of individuals vaccinated against COVID-19, partisan differences surrounding the COVID-19 vaccine emerged, creating a potential challenge for health communications aimed at increasing vaccine uptake. A better understanding of partisan differences in attitudes and intentions towards vaccination may help guide public health strategies aimed at increasing vaccine uptake. To determine whether a commonly used theory of behavioral intentions used to craft public health messages explains partisan differences in intentions. Data were drawn from a national panel of US adults and collected between February 21, 2022, and March 3, 2022, using an online survey (n = 1845). Among respondents identifying as either Democrat or Republican (n = 1466), path analysis models were estimated to test whether partisan differences in vaccination or booster intentions were explained by the theoretical constructs of protection motivation theory (PMT). PMT accounted for approximately half of the covariate-adjusted mean difference in COVID-19 vaccination intentions between Democrats and Republicans, and nearly all the mean difference in booster intentions. Party affiliation indirectly affected intentions via its association with perceived susceptibility to COVID-19, vaccine/booster efficacy, and perceived costs of getting a COVID-19 vaccine or booster dose. Compared with Democrats, Republicans may be less likely to get vaccinated or receive a booster dose because of beliefs that they are less susceptible to COVID-19, that the vaccine is less effective, and that vaccination comes with disadvantages. Theories of behavioral intentions can help to identify the underlying theoretical determinants driving behavioral differences between political groups.

Electronic Versus Paper and Pencil Survey Administration Mode Comparison: 2019 Youth Risk Behavior Survey.

BACKGROUND: Since the inception of the Youth Risk Behavior Surveillance System in 1991, all surveys have been conducted in schools, using paper and pencil instruments (PAPI). For the 2019 YRBSS, sites were offered the opportunity to conduct their surveys using electronic data collection. This study aimed to determine whether differences in select metrics existed between students who completed the survey electronically versus using PAPI. METHODS: Thirty risk behaviors were examined in this study. Data completeness, response rates and bivariate comparisons of risk behavior prevalence between administration modes were examined. RESULTS: Twenty-nine of 30 questions examined had more complete responses among students using electronic surveys. Small differences were found for student and school response rates between modes. Twenty-five of 30 adolescent risk behaviors showed no mode effect. CONCLUSIONS: Seven of 44 states and DC participated electronically. Because survey data were more complete; school and student response rates were consistent; and minor differences existed in risk behaviors between modes, the acceptability of collecting data electronically was demonstrated.

Overview and Methodology of the Adolescent Behaviors and Experiences Survey - United States, January-June 2021.

Many U.S. schools closed nationwide in March 2020 to prevent the spread of COVID-19. School closures and online-only instruction have negatively affected certain students, with studies showing adverse effects of the pandemic on mental health. However, little is known about other experiences such as economic and food insecurity and abuse by a parent, as well as risk behaviors such as alcohol and drug use among youths across the United States during the pandemic. To address this gap, CDC developed the one-time, online Adolescent Behaviors and Experiences Survey (ABES), which was conducted during January-June 2021 to assess student behaviors and experiences during the COVID-19 pandemic among high school students, including unintentional injury, violence, tobacco product use, sexual behaviors, and dietary behaviors. This overview report of the ABES MMWR Supplement describes the ABES methodology, including the student questionnaire and administration, sampling, data collection, weighting, and analysis. ABES used a stratified, three-stage cluster probability-based sampling approach to obtain a nationally representative sample of students in grades 9-12 attending public and private schools. Teachers of selected classes provided students with access to the anonymous online survey while following local consent procedures. Data were collected using a 110-item questionnaire during January-June 2021 in 128 schools. A total of 7,998 students submitted surveys, and 7,705 of these surveys had valid data (i.e., ≥20 questions answered). The school response rate was 38%, the student response rate was 48%, and the overall response rate was 18%. Information on mode of instruction and school-provided equipment was also collected from all sampled schools. This overview report provides student- and school-level characteristics obtained from descriptive analyses, and the other reports in the ABES MMWR Supplement include information on substance use, mental health and suicidality, perceived racism, and disruptions to student life among high school students. Findings from ABES during the COVID-19 pandemic can help guide parents, teachers, school administrators, community leaders, clinicians, and public health officials in decision-making for student support and school health programs.

Prevalence of Planned Abdominal Binder Use after Vaginal Delivery.

OBJECTIVES: Pregnancy and vaginal delivery are risk factors for pelvic floor dysfunction. Abdominal binder use may increase intraabdominal pressure, affecting pelvic floor healing or function in recently traumatized postpartum pelvic floor muscle. This study assesses the prevalence of postpartum abdominal binder use, timing, and reasons for use. METHODS: In this cross-sectional observational survey study, women who underwent a vaginal delivery at our institution were enrolled. Participants were excluded if they did not speak Spanish or English. Participants were recruited on the postpartum unit. Data were deidentified and analyzed as appropriate for each variable. RESULTS: In total, 673 surveys were completed. Seven were excluded because they had cesarean deliveries. The average age was 26 years. Median gravidity and parity were 2 and 2. In total, 549 women (82%) planned to wear an abdominal binder postpartum. In all, 335 women provided a specific time when they would start use: 240 women (71%) would start at ≤2 days postpartum, 60 women (18%) would start at 3 to 7 days postpartum, and 35 women (11%) would start after 1 week postpartum. Common reasons reported for use included appearance, support, pain, swelling, weight loss, and recommendation. CONCLUSIONS: Among women delivering at our institution, planned abdominal binder use postvaginal delivery is common. The reasons cited include health and desire to return to prior body shape. The effects of using an abdominal binder in the postpartum period are unknown. More research is needed to better elucidate how increased postpartum intraabdominal pressure affects healing in traumatized pelvic floor muscles.

Health Risk Behaviors, Experiences, and Conditions Among Students Attending Private and Public High Schools.

BACKGROUND: Approximately 8.8% of US high school students attended private schools in 2015. Few studies have characterized health risk behaviors among these students or compared prevalence of behaviors between students in private and public schools using a contemporary, nationally representative sample. METHODS: Pooled 2007-2017 national Youth Risk Behavior Survey data were used to estimate the prevalence of 35 health risk behaviors for 89,848 public and private high school students. Unadjusted prevalence ratios were used to compare prevalence by school type. Differences in behaviors by school type were explored by sex and grade. RESULTS: Among private school students, the prevalence ranged from 5.0% to 31.9% for sexual risk behaviors; from 0.8% to 30.1% for substance use behaviors; from 0.7% to 21.8% for behaviors related mental health and suicide; from 3.2% to 6.8% for violence victimization experiences; and from 3.1% to 52.9% for behaviors related to unhealthy diet and physical inactivity. Private school students were less likely than public school students to report most behaviors; differences by school type were generally consistent across sex and grade. CONCLUSIONS: Students in both public and private schools reported health risk behaviors. Findings might inform prevention activities by identifying behaviors to prioritize in each school setting.

School-Level Poverty and Rurality Associated With Differences in Sexual Risk Behaviors Among U.S. Public High School Students.

PURPOSE: This study examined associations between student sexual behaviors and both school-level socioeconomic status and metropolitan status. METHODS: National Youth Risk Behavior Survey data from 2017 (N = 14,765, response rate = 60%) and 2019 (N = 13,677, 60%) were combined. School-level socioeconomic status (low-, mid-, and high-poverty based on the percentage of students eligible for free or reduced-price meals) and metropolitan status (urban, suburban/town, or rural) were identified for students attending public high schools. Sexual behaviors included currently sexually active, four or more lifetime sexual partners, condom use during the last sexual intercourse, hormonal birth control use during the last sexual intercourse, condom and hormonal birth control use during the last sexual intercourse, and drank alcohol or used drugs before the last sexual intercourse. Adjusted prevalence ratios were calculated using logistic regression models, controlling for sex, race/ethnicity, and grade. RESULTS: Compared to students attending low-poverty schools, high-poverty school students were significantly more likely to be currently sexually active (adjusted prevalence ratio = 1.4 [95% confidence interval = 1.1-1.8]) and have four or more lifetime sexual partners (1.6 [1.0-2.5]), but were significantly less likely to have drank alcohol or used drugs before the last sexual intercourse (.7 [.5-.9]) and have used hormonal birth control during the last sexual intercourse (.7 [.6-1.0]). Compared to students attending rural schools, urban school students were significantly less likely to be currently sexually active (.8 [.7-.9]) and have four or more lifetime sexual partners (.7 [.5-.9]). CONCLUSIONS: School-level socioeconomic status and metropolitan status were associated with differential risk in sexual behaviors.

Transportation Risk Behaviors Among High School Students - Youth Risk Behavior Survey, United States, 2019.

Motor-vehicle crashes are a leading cause of death and nonfatal injury among U.S. adolescents, resulting in approximately 2,500 deaths and 300,000 nonfatal injuries each year. Risk for motor-vehicle crashes and resulting injuries and deaths varies, depending on such behaviors as seat belt use or impaired or distracted driving. Improved understanding of adolescents' transportation risk behaviors can guide prevention efforts. Therefore, data from the 2019 Youth Risk Behavior Survey were analyzed to determine prevalence of transportation risk behaviors, including not always wearing a seat belt, riding with a driver who had been drinking alcohol (riding with a drinking driver), driving after drinking alcohol, and texting or e-mailing while driving. Differences by student characteristics (age, sex, race/ethnicity, academic grades in school, and sexual identity) were calculated. Multivariable analyses controlling for student characteristics examined associations between risk behaviors. Approximately 43.1% of U.S. high school students did not always wear a seat belt and 16.7% rode with a drinking driver during the 30 days before the survey. Approximately 59.9% of students had driven a car during the 30 days before the survey. Among students who drove, 5.4% had driven after drinking alcohol and 39.0% had texted or e-mailed while driving. Prevalence of not always wearing a seat belt was higher among students who were younger, black, or had lower grades. Riding with a drinking driver was higher among Hispanic students or students with lower grades. Driving after drinking alcohol was higher among students who were older, male, Hispanic, or had lower grades. Texting while driving was higher among older students or white students. Few differences existed by sexual identity. Multivariable analyses revealed that students engaging in one transportation risk behavior were more likely to engage in other transportation risk behaviors. Traffic safety and public health professionals can use these findings to reduce transportation risk behaviors by selecting, implementing, and contextualizing the most appropriate and effective strategies for specific populations and for the environment.

Overview and Methods for the Youth Risk Behavior Surveillance System - United States, 2019.

Health risk behaviors practiced during adolescence often persist into adulthood and contribute to the leading causes of morbidity and mortality in the United States. Youth health behavior data at the national, state, territorial, tribal, and local levels help monitor the effectiveness of public health interventions designed to promote adolescent health. The Youth Risk Behavior Surveillance System (YRBSS) is the largest public health surveillance system in the United States, monitoring a broad range of health-related behaviors among high school students. YRBSS includes a nationally representative Youth Risk Behavior Survey (YRBS) and separate state, local school district, territorial, and tribal school-based YRBSs. This overview report describes the surveillance system and the 2019 survey methodology, including sampling, data collection procedures, response rates, data processing, weighting, and analyses presented in this MMWR Supplement. A 2019 YRBS participation map, survey response rates, and student demographic characteristics are included. In 2019, a total of 78 YRBSs were administered to high school student populations across the United States (national and 44 states, 28 local school districts, three territories, and two tribal governments), the greatest number of participating sites with representative data since the surveillance system was established in 1991. The nine reports in this MMWR Supplement are based on national YRBS data collected during August 2018-June 2019. A full description of 2019 YRBS results and downloadable data are available (https://www.cdc.gov/healthyyouth/data/yrbs/index.htm).Efforts to improve YRBSS and related data are ongoing and include updating reliability testing for the national questionnaire, transitioning to electronic survey administration (e.g., pilot testing for a tablet platform), and exploring innovative analytic methods to stratify data by school-level socioeconomic status and geographic location. Stakeholders and public health practitioners can use YRBS data (comparable across national, state, tribal, territorial, and local jurisdictions) to estimate the prevalence of health-related behaviors among different student groups, identify student risk behaviors, monitor health behavior trends, guide public health interventions, and track progress toward national health objectives.

Does hypertension at initial presentation adversely affect outcomes in pediatric traumatic brain injury?

BACKGROUND: Adults with traumatic brain injury (TBI) who present hypertensive suffer worse outcomes and increased mortality compared to normotensive patients. The purpose of this study is to determine if age-adjusted hypertension on presentation is associated with worsened outcomes in pediatric TBI. METHODS: A retrospective chart review was conducted on pediatric patients with severe TBI admitted to a single system pediatric tertiary care center. The primary outcome was mortality. Secondary outcomes included length of stay, need for neurosurgical intervention, duration of mechanical ventilation, and the need for inpatient rehabilitation. RESULTS: Of 150 patients, 70% were hypertensive and 30% were normotensive on presentation. Comparing both groups, no statistically significant differences were noted in mortality (13.3% for both groups), need for neurosurgical intervention (51.4% vs 48.8%, p = 0.776), length of stay (6 vs 8 days, p = 0.732), duration of mechanical ventilation (2 vs 3 days, p = 0.912), or inpatient rehabilitation rates (48.6% vs 48.9%, p = 0.972). In comparing just the hypertensive patients, there was a trend toward increased mortality in the 95th and 99th percentile groups at 15.8% and 14.1%, versus the 90th percentile group at 6.7% but the difference was not statistically significant (p = 0.701). CONCLUSIONS: Contrary to the adult literature, pediatric patients with severe TBI and hypertension on presentation do not appear to have worsened outcomes compared to those who are normotensive. However, a trend toward increased mortality did exist at extremes of age adjusted hypertension. Larger scale studies are needed to validate these findings. STUDY TYPE: Retrospective cohort study LEVEL OF EVIDENCE: III.

Long-Term Clinical Outcomes and Parental Satisfaction After Dextranomer/Hyaluronic Acid (Dx/HA) Injection for Primary Vesicoureteral Reflux.

Purpose: Endoscopic dextranomer/hyaluronic acid (Dx/HA) injection is a common treatment for vesicoureteral reflux (VUR) with excellent reported short-term clinical success rates. Long-term outcomes are less well-defined. We assessed long-term outcomes and parental satisfaction after Dx/HA injection for primary VUR with >5-year follow-up. Materials and Methods: Families of all patients who underwent Dx/HA injection for primary VUR at our institution between 2008 and 2012 were contacted for telephone interview. Data collected by phone included parental satisfaction and presence and severity of UTIs pre-operatively and post-operatively. Patient demographics, radiographic VUR data, need for secondary surgery, and surgical indications were obtained through chart review. Results: Five hundred and seventy-five patients underwent Dx/HA injection for primary VUR between 2008 and 2012. Ninety-nine (17.2%) of these patients' parents were successfully contacted and interviewed. Median follow-up time from surgery to survey was 8.4 (IQR 6.8-9.6) years. Secondary surgery was performed in 13/99 (13.1%), most commonly repeat Dx/HA injection. Seven patients (7.1%) underwent secondary Dx/HA injection for persistent VUR without UTIs at a median of 0.35 (IQR 0.33-0.77) years post-operatively. Five patients (5.1%) underwent Dx/HA injection (n = 3) or ureteral reimplantation (n = 2) for VUR with febrile UTIs (fUTIs) at a median of 2.2 (IQR 1.3-5.1) years. One patient had ureteral reimplantation for symptomatic obstruction 2.8 years after initial surgery. Only 3/99 (3.0%) required open or laparoscopic surgery after Dx/HA injection. Eighty-three families (84.7%) reported ≥1 fUTIs pre-operatively. Of these, only 9/83 (10.8%) reported fUTIs post-operatively, for an overall clinical success rate of 89.2%. Clinical success was 93.1% in patients whose pre-operative fUTIs were treated outpatient and 80.0% in those hospitalized at least once for fUTI treatment pre-operatively. Ninety-four percent of parents were highly satisfied, 2.4% partially satisfied, and 3.5% dissatisfied. Conclusions: Endoscopic injection with Dx/HA for primary VUR appears to have good long-term clinical success rates and high parental satisfaction, mirroring our previously reported short-term results. Post-operative ureteral obstruction is rare but may occur years post-operatively, justifying initial sonographic surveillance, and repeat imaging in symptomatic patients.

Modified-Bolus Placement as a Therapeutic Tool in the Treatment of Pediatric Feeding Disorders: Analysis From a Retrospective Chart Review.

Purpose Recognizing the need to advance the treatment of pediatric feeding disorders, an emerging area of inquiry focuses on therapeutic techniques that address expulsion and packing possibly associated with oral-motor dysfunction. In the current study, we documented the use of modified-bolus placement in the treatment of pediatric feeding disorders at an intensive, multidisciplinary day-treatment center over a 26-month period. Method The retrospective observational cohort study involved patients admitted for the assessment and treatment of chronic food refusal from August 2013 to October 2015. Results Patients (n = 23) who received modified bolus placement displayed moderate-to-severe oral-motor deficits. Use of modified-bolus placement was associated with reduced expulsion and packing of bites during meals, and treatment gains coincided with a threefold increase in grams consumed per meal. Conclusion Results provide additional support for the potential therapeutic benefits of enhancing bolus placement onto the tongue as a means to improve mealtime performance in children with pediatric feeding disorders when included as an adjunct to more traditional behavioral approaches.

Primary versus secondary anastomosis in intestinal atresia.

PURPOSE: Neonates with intestinal atresia (IA) undergo either primary anastomosis (PA) or ostomy creation with secondary anastomosis (SA). Our purpose was to compare outcomes for PA and SA and to assess factors influencing procedure selection. METHODS: We conducted a retrospective cohort study of neonates with IA between 2009 and 2015. Patient characteristics, operative details, and outcomes were collected. Surgeon-level preferences (defined as performing >50% PA or SA) were assessed using logistic regression. RESULTS: Of 92 IA patients, 70 (76.1%) underwent PA and 22 (23.9%) underwent SA. Neonates with PA had shorter hospitalizations (27 days vs. 95 days, p < 0.001), shorter total parenteral nutrition duration (19 days vs. 74.5 days, p < 0.001), and fewer readmissions (33.3% vs. 63.2%, p = 0.024). On multivariable regression analysis, higher Apgar scores (Odds Ratio (OR) 4.16, 95% Confidence Interval (CI) 1.20-14.29) and uncomplicated atresia (OR 3.97, 95% CI 1.37-11.48) were associated with PA. At the surgeon-level, utilization of PA varied from 43.5% to 100%. Surgeon preference is not influenced by the demographic, presentation, or surgical findings of this patient population. CONCLUSIONS: PA has better outcomes than SA. Though procedural selection is influenced by the clinical status of the neonate, however surgeon preference plays a significant role in this clinical decision. LEVEL OF EVIDENCE: Level III Treatment Study.

The Impact of Disruption of the Care Delivery System by Commercial Laboratory Testing in a Children's Health Care System.

CONTEXT.­: Disruption of outpatient laboratory services by routing the samples to commercial reference laboratories may seem like a cost-saving measure by the payers, but results in hidden costs in quality and resources to support this paradigm. OBJECTIVE.­: To identify differences when outpatient tests are performed at the Children's Healthcare of Atlanta (Children's) Hospital lab compared to a commercial reference lab, and the financial costs to support the reference laboratory testing. DESIGN.­: Outpatient testing was sent to 3 different laboratories specified by the payer. Orders were placed in the Children's electronic health record, blood samples were drawn by the Children's phlebotomists, samples were sent to the testing laboratory, and results appeared in the electronic health record. Data comparing the time to result, cancelled samples, and cost to sustain the system of ordering and reporting were drawn from multiple sources, both electronic and manual. RESULTS.­: The median time from phlebotomy to result was 0.7 hours for testing at the Children's lab and 20.72 hours for the commercial lab. The median time from result posting to caregiver acknowledgment was 5.4 hours for the Children's lab and 18 hours for the commercial lab. The commercial lab cancelled 2.7% of the tests; the Children's lab cancelled 0.8%. The financial cost to support online ordering and reporting for testing performed at commercial labs was approximately $640,000 per year. CONCLUSIONS.­: Tangible monetary costs, plus intangible costs related to delayed results, occur when the laboratory testing system is disrupted.

Comparison of a Smartphone Otoscope and Conventional Otoscope in the Diagnosis and Management of Acute Otitis Media.

Acute otitis media (AOM) is a leading cause of health encounters and antimicrobial prescriptions in children worldwide. We assessed (1) the rates of antimicrobial prescribing by pediatric emergency department clinicians using a smartphone otoscope device as compared with a conventional otoscope and (2) clinician acceptability of the smartphone device. We conducted a randomized control study in children's hospital emergency departments over 6 months. More than 1500 encounters were analyzed. The odds of prescribing antibiotics after being given a diagnosis of AOM by clinicians assigned to the smartphone group was 11% higher than the conventional group (18.8% vs 18.0%, odds ratio = 1.106, P = .600). Eight (73%) of the 11 physicians in the smartphone group preferred the smartphone device over the conventional otoscope. Use of a smartphone otoscope for detection of AOM in a pediatric emergency department setting did not lead to an increased likelihood of AOM diagnosis.

Small separation diffuse correlation spectroscopy for measurement of cerebral blood flow in rodents.

Diffuse correlation spectroscopy (DCS) has shown promise as a means to non-invasively measure cerebral blood flow in small animal models. Here, we characterize the validity of DCS at small source-detector reflectance separations needed for small animal measurements. Through Monte Carlo simulations and liquid phantom experiments, we show that DCS error increases as separation decreases, although error remains below 12% for separations > 0.2 cm. In mice, DCS measures of cerebral blood flow have excellent intra-user repeatability and strongly correlate with MRI measures of blood flow (R = 0.74, p<0.01). These results are generalizable to other DCS applications wherein short-separation reflectance geometries are desired.

Hunger: A Missed Opportunity for Screening in the Pediatric Emergency Department.

BACKGROUND: The American Academy of Pediatrics and pediatric community recognize the importance of addressing social determinants of health. There are limited data on the prevalence of food insecurity or literature establishing protocols assessing food insecurity in the emergency department (ED). METHODS: Two anonymous surveys were administered, one to families during their ED visit and another to ED staff to assess perceptions on the ED's role in providing social support. RESULTS: Thirty-three of 214 respondents (15.4%) reported food insecurity and are associated with economic risk factors ( P < .0001) and a lack of primary care ( P = .008). Overall, 83.2% of the ED staff believed knowing information about families' social risk factors would help patient care and 77.6% believed that the ED staff should address families' social needs. CONCLUSIONS: Food insecurity affects a significant portion of ED families across income ranges. Screening for food insecurity in the ED is important given association with lack of primary care. Hospital staff supports screening and intervention.

Procedural sedation in children with autism spectrum disorders: A survey of current practice patterns of the society for pediatric sedation members.

BACKGROUND: Children with autism spectrum disorder are challenging to sedate because of communication, sensory, and behavioral challenges. AIMS: The aim of this survey was to determine how procedural sedation is provided to children with autism spectrum disorders and whether sedation programs have specialized protocols for procedural sedation of these children. METHODS: We surveyed physician Medical Directors of sedation programs who are members of the Society for Pediatric Sedation, asking about practice characteristics and resource utilization during procedural sedation of children with autism spectrum disorders. RESULTS: Of 58 directors, 47 (81%) responded. Of the programs surveyed, 53% were either a large university medical center and 40% were a freestanding children's hospital. Only (12/47, 25.5%) of the programs used an individualized autism coping plan. To accomplish procedural sedation in this study cohort, 36% of the programs used additional nurses, whereas a child life specialist was used in 55% of the programs surveyed. Only 28% of the centers allotted additional time to accommodate children with autism spectrum disorders. Distraction methods were used in 80% whereas restrains were used in 45% programs for were used most commonly for i.v. catheter placement. Propofol was the preferred agent for 70% of programs for imaging, while propofol + fentanyl was used by 66% of programs for painful procedures. Although 57% of directors reported that their program staff was extremely comfortable providing procedural sedation for children with autism spectrum disorder, 79% of the directors wanted more education about behavioral management strategies for procedural sedation of these children. CONCLUSION: Among the Society for Pediatric Sedation programs, significant institutional variation exists on the delivery of procedural sedation to children with autism spectrum disorders. A better understanding of resources required, standardization of behavioral management strategies and pharmacologic approaches, and protocol development may help optimize care to this vulnerable population.

Factors affecting same-day cancelation of outpatient pediatric oncologic procedural sedation.

BACKGROUND: Children with cancer undergo serial invasive, painful procedures as a part of their diagnosis, treatment, and surveillance regimens that require procedural sedation (PS). Some may have a delay in their treatment plan due to same-day cancelation (SDC) of the procedure due to issues related to sedation or other factors. The objective of this report was to evaluate the factors resulting in the SDC of hematology and oncology patients in an outpatient pediatric sedation service. METHODS: Retrospective review of children with cancer or other hematologic disorders undergoing outpatient procedures using a dedicated pediatric sedation team from January 2012 to December 2017. The children with SDC were compared to controls (ie, patients not canceled) during the above study period. RESULTS: A total of 100 patients had SDC during the study. The median age was 10 years (25th percentile to 75th percentile: 7-10 years). The overall SDC rate was 3% and 78/100 (78%) had acute lymphoblastic leukemia. Most common procedure was lumbar puncture with intrathecal chemotherapy in 82/100 (82%) patients. Inadequate blood counts, acute illness, and not nil per os (NPO) accounted for 83% of the reasons for SDC. Type of health insurance, estimated household income, or distance traveled to the clinic did not impact SDC. CONCLUSIONS: The most common factors for SDC included inadequate blood counts, acute illness, and not meeting NPO guidelines. Understanding factors affecting SDC may help improve the efficiency of time-sensitive care delivered to children with cancer and other hematologic concerns by a pediatric sedation service.

Prevalence of Amyotrophic Lateral Sclerosis - United States, 2012-2013.

PROBLEM/CONDITION: Amyotrophic lateral sclerosis (ALS), commonly known as Lou Gehrig's disease, is a progressive and fatal neuromuscular disease for which no cure or viable treatment has been identified. ALS, like most noncommunicable diseases, is not a nationally notifiable disease in the United States. The prevalence of ALS in the United States during 2010-2011 was estimated to be 3.9 cases per 100,000 persons in the general population. Updated prevalence estimates are needed to help monitor disease status, better understand etiology, and identify risk factors for ALS. PERIOD COVERED: 2012-2013. DESCRIPTION OF SYSTEM: The National ALS Registry, established in 2009, collects data on ALS patients in the United States to better describe the incidence and prevalence of ALS, examine risk factors such as environmental and occupational exposures, and characterize the demographics of those living with ALS. To identify prevalent cases of ALS, data are compiled from four national administrative databases (maintained by the Centers for Medicare and Medicaid Services, the Veterans Health Administration, and the Veterans Benefits Administration). To identify cases not included in these databases and to better understand risk-factors associated with ALS and disease progression, the Registry also includes data that are collected from patients who voluntarily enroll and complete online surveys. RESULTS: During 2012 and 2013, the Registry identified 14,713 and 15,908 persons, respectively, who met the surveillance case definition of ALS. The estimated ALS prevalence rate was 4.7 cases per 100,000 U.S. population for 2012 and 5.0 per 100,000 for 2013. Due to revisions to the algorithm and use of death data from the National Death Index, an updated prevalence estimate has been calculated retrospectively for October 19, 2010-December 31, 2011. This updated estimate showed a prevalence rate of 4.3 per 100,000 population and a total of 13,282 cases. Since the inception of the Registry, the pattern of characteristics (e.g., age, sex, and race/ethnicity) among persons with ALS have remained unchanged. Overall, ALS was more common among whites, males, and persons aged 60-69 years. The age groups with the lowest number of ALS cases were persons aged 18-39 years and those aged ≥80 years. Males had a higher prevalence rate of ALS than females overall and across all data sources. These findings remained consistent during October 2010-December 2013. INTERPRETATION: The Registry is the only available data source that can be used to estimate the national prevalence for ALS in the United States. Use of both administrative national databases and self-report from patients enables a comprehensive approach to estimate ALS prevalence. The overall increase in the prevalence rate from 4.3 per 100,000 persons (revised) during 2010-2011 to 4.7 and 5.0 per 100,000 persons, respectively, during 2012-2013 likely is not an actual increase in the number of ALS cases. Rather, this increase might be attributed to improved case ascertainment due to the refinement of the algorithm used to identify definite ALS cases, along with an increased public awareness of the Registry. Registry estimates of ALS prevalence are consistent with findings from long-established ALS registries in Europe and from smaller-scale epidemiologic studies previously conducted in the United States. PUBLIC HEALTH ACTIONS: Data collected by the National ALS Registry are being used to better describe the epidemiology of ALS in the United States and to help facilitate research. The combined approach of using national administrative databases and a self-enrollment web portal to collect data is novel and potentially could be used for other non-notifiable diseases such as Parkinson's disease or multiple sclerosis. Increased public awareness of the Registry might lead to more ALS cases being identified from the secure web portal (https://www.cdc.gov/als), which can ascertain cases apart from the national administrative databases. For example, in 2014, the ALS Ice Bucket Challenge, a social media-centered campaign, received extensive public visibility and created increased awareness of ALS. The Agency for Toxic Substances and Disease Registry (ATSDR) works closely with ALS advocacy and support groups, researchers, health care professionals, and others to promote the National ALS Registry and to identify all cases of ALS in the United States. In addition to estimating the prevalence of ALS, the Registry is being used to collect specimens from patient enrollees through a new biorepository, connect patient enrollees with new clinical trials and epidemiologic studies, and fund studies to help learn more about the etiology of ALS. Additional information about the National ALS Registry is available at http://www.cdc.gov/als or by calling toll-free at 1-877-442-9719.

Preliminary Results of National Amyotrophic Lateral Sclerosis (ALS) Registry Risk Factor Survey Data.

BACKGROUND: The National ALS Registry is made up of two components to capture amyotrophic lateral sclerosis (ALS) cases: national administrative databases (Medicare, Medicaid, Veterans Health Administration and Veterans Benefits Administration) and self-identified cases captured by the Registry's web portal. This study describes self-reported characteristics of U.S. adults with ALS using the data collected by the National ALS Registry web portal risk factor surveys only from October 19, 2010 through December 31, 2013. OBJECTIVE: To describe findings from the National ALS Registry's web portal risk factor surveys. MEASUREMENTS: The prevalence of select risk factors among adults with ALS was determined by calculating the frequencies of select risk factors-smoking and alcohol (non, current and former) histories, military service and occupational history, and family history of neurodegenerative diseases such as ALS, Alzheimer's and/or Parkinson's. RESULTS: Nearly half of survey respondents were ever smokers compared with nearly 41% of adults nationally. Most respondents were ever drinkers which is comparable to national estimates. The majority were light drinkers. Nearly one-quarter of survey respondents were veterans compared with roughly 9% of US adults nationally. Most respondents were retired or disabled. The industries in which respondents were employed for the longest time were Professional and Scientific and Technical Services. When family history of neurodegenerative diseases in first degree relatives was evaluated against our comparison group, the rates of ALS were similar, but were higher for Parkinson's disease, Alzheimer's disease and any neurodegenerative diseases. CONCLUSIONS: The National ALS Registry web portal, to our knowledge, is the largest, most geographically diverse collection of risk factor data about adults living with ALS. Various characteristics were consistent with other published studies on ALS risk factors and will allow researchers to generate hypotheses for future research.
