Lessons learned from the whole child and coordinated school health approaches
Rasberry CN , Slade S , Lohrmann DK , Valois RF . J Sch Health 2015 85 (11) 759-65 BACKGROUND: The new Whole School, Whole Community, Whole Child (WSCC) model, designed to depict links between health and learning, is founded on concepts of coordinated school health (CSH) and a whole child approach to education. METHODS: The existing literature, including scientific articles and key publications from national agencies and organizations, was reviewed and synthesized to describe (1) the historical context for CSH and a whole child approach, and (2) lessons learned from the implementation and evaluation of these approaches. RESULTS: The literature revealed that interventions conducted in the context of CSH can improve health-related and academic outcomes, as well as policies, programs, or partnerships. Several structural elements and processes have proved useful for implementing CSH and a whole child approach in schools, including use of school health coordinators, school-level and district-level councils or teams; systematic assessment and planning; strong leadership and administrative support, particularly from school principals; integration of health-related goals into school improvement plans; and strong community collaborations. CONCLUSIONS: Lessons learned from years of experience with CSH and the whole child approaches have applicability for developing a better understanding of the WSCC model as well as maximizing and documenting its potential for impacting both health and education outcomes. |
Update on prevalence of periodontitis in adults in the United States: NHANES 2009-2012
Eke PI , Dye BA , Wei L , Slade GD , Thornton-Evans GO , Borgnakke WS , Taylor GW , Page RC , Beck JD , Genco RJ . J Periodontol 2015 86 (5) 1-18 This report describes prevalence, severity, and extent of periodontitis in the US adult population using combined data from the 2009-2010 and 2011-2012 cycles of the National Health and Nutrition Examination Survey (NHANES). METHODS: Estimates were derived for dentate adults 30 years and older from the civilian non-institutionalized population. Periodontitis was defined by combinations of clinical attachment loss (CAL) and periodontal probing depth (PPD) from six sites per tooth on all teeth, except third molars, using standard surveillance case definitions. For the first time in NHANES history, sufficient numbers of Non-Hispanic Asians were sampled in 2011-2012 to provide reliable estimates of their periodontitis prevalence. RESULTS: In 2009-2012, 46% of US adults representing 64.7 million people had periodontitis, with 8.9% having severe periodontitis. Overall, 3.8% of all periodontal sites (10.6% of all teeth) had PPD≥4 mm and 19.3% of sites (37.4% teeth) had CAL≥3 mm. Periodontitis prevalence was positively associated with increasing age and was higher among males. Periodontitis prevalence was highest in Hispanics (63.5%) and Non-Hispanic blacks (59.1%), followed by Non-Hispanic Asian Americans (50.0%), and lowest in Non-Hispanic whites (40.8%). Prevalence varied two-fold between the lowest and highest levels of socioeconomic status, whether defined by poverty or education. CONCLUSION(S): This study confirms a high prevalence of periodontitis in US adults aged 30 years and older, with almost half affected. The prevalence was greater in Non-Hispanic Asians than Non-Hispanic whites, although lower than other minorities. The distribution provides valuable information for population-based action to prevent or manage periodontitis in US adults. |
U.S. postlicensure safety surveillance for adolescent and adult tetanus, diphtheria and acellular pertussis vaccines: 2005-2007
Chang S , O'Connor PM , Slade BA , Woo EJ . Vaccine 2013 31 (10) 1447-52 BACKGROUND: Pre-licensure clinical trials for two U.S. licensed tetanus toxoid, reduced diphtheria toxoid and acellular pertussis (Tdap) vaccines did not reveal any major safety concerns. However, routine use in large adolescent and adult populations could reveal rare and potentially serious adverse events (AEs). METHODS: To characterize reported AEs following Tdap vaccination and identify potential safety concerns warranting further evaluation, we analyzed data from the Vaccine Adverse Event Reporting System (VAERS) and assessed the frequency and proportions of AEs and reporting rates (reports per 100,000 vaccine doses distributed). RESULTS: A total of 2090 reports (7% were serious; 55% listed Tdap alone) involving Tdap vaccines were submitted to VAERS May 2005-June 2007. The crude reporting rate was 10.2 per 100,000 vaccine doses distributed. The median age of vaccinees was 22 years, and the female to male ratio was about 2 to 1. The majority of reports described common local and systemic signs and symptoms, such as injection site reactions, fever, and headache. Rarely reported AEs included myopericarditis, demyelinating diseases of the central nervous system, Guillain-Barre Syndrome, syncope, encephalopathy/encephalitis, seizure, Bell's palsy, anaphylaxis, and thrombocytopenia. CONCLUSIONS: Because adolescents and adults were not routinely vaccinated against pertussis in the past, this surveillance summary provides important - and reassuring - information about the use of Tdap in these age groups. Although subject to the limitations of passive surveillance, the findings of this VAERS review support the pre-licensure clinical trial data with regard to the safety of the U.S. licensed Tdap vaccines. Continued monitoring of clinically significant AEs that are temporally associated with Tdap vaccination and further assessment of such events using controlled observational studies may provide additional information about the safety of these vaccines. |

Pahud BA , Williams SE , Dekker CL , Halsey N , Larussa P , Baxter RP , Klein NP , Marchant CD , Sparks RC , Jakob K , Aukes L , Swope S , Barnett E , Lewis P , Berger M , Dreskin SC , Donofrio PD , Sejvar JJ , Slade BA , Gidudu J , Vellozzi C , Edwards KM . Pediatr Infect Dis J 2013 32 (2) 163-168 BACKGROUND: Monovalent 2009 H1N1 influenza vaccines were licensed and administered in the United States during the H1N1 influenza pandemic between 2009 and 2013. METHODS: Vaccine Adverse Event Reporting System received reports of adverse events following immunization (AEFI) after H1N1 vaccination. Selected reports were referred to the Centers for Disease Control and Prevention's Clinical Immunization Safety Assessment network for additional review. We assessed causality using modified World Health Organization criteria. RESULTS: There were 3,928 reports of AEFI in children younger than age 18 years after 2009 H1N1 vaccination received by January 31, 2010. Of these, 214 (5.4%) were classified as serious nonfatal and 109 were referred to Clinical Immunization Safety Assessment for further evaluation. Ninety-nine (91%) had sufficient initial information to begin investigation and are described here. The mean age was 8 years (range, 6 months-17 years) and 38% were female. Median number of days between vaccination and symptom onset was 2 (range, -11 days to +41 days). Receipt of inactivated, live attenuated, or unknown type of 2009 H1N1 vaccines was reported by 68, 26 and 5 cases, respectively. Serious AEFI were categorized as neurologic events in 47 cases, as hypersensitivity in 15 cases and as respiratory events in 10 cases. At the time of evaluation, recovery was described as complete (61), partial (16), no improvement (1), or unknown (21). Causality assessment yielded the following likelihood of association with 2009 H1N1 vaccination: 8 definitely; 8 probably; 21 possibly; 43 unlikely; 17 unrelated; and 2 unclassifiable. CONCLUSIONS: Most AEFI in children evaluated were not causally related to vaccine and resolved without sequelae. Detailed clinical assessment of individual serious AEFI can provide reassurance of vaccine safety. |
Algorithm to assess causality after individual adverse events following immunizations
Halsey NA , Edwards KM , Dekker CL , Klein NP , Baxter R , Larussa P , Marchant C , Slade B , Vellozzi C . Vaccine 2012 30 (39) 5791-5798 Assessing individual reports of adverse events following immunizations (AEFI) can be challenging. Most published reviews are based on expert opinions, but the methods and logic used to arrive at these opinions are neither well described nor understood by many health care providers and scientists. We developed a standardized algorithm to assist in collecting and interpreting data, and to help assess causality after individual AEFI. Key questions that should be asked during the assessment of AEFI include: Is the diagnosis of the AEFI correct? Does clinical or laboratory evidence exist that supports possible causes for the AEFI other than the vaccine in the affected individual? Is there a known causal association between the AEFI and the vaccine? Is there strong evidence against a causal association? Is there a specific laboratory test implicating the vaccine in the pathogenesis? An algorithm can assist with addressing these questions in a standardized, transparent manner which can be tracked and reassessed if additional information becomes available. Examples in this document illustrate the process of using the algorithm to determine causality. As new epidemiologic and clinical data become available, the algorithm and guidelines will need to be modified. Feedback from users of the algorithm will be invaluable in this process. We hope that this algorithm approach can assist with educational efforts to improve the collection of key information on AEFI and provide a platform for teaching about causality assessment. |
Causality assessment of serious neurologic adverse events following 2009 H1N1 vaccination
Williams SE , Pahud BA , Vellozzi C , Donofrio PD , Dekker CL , Halsey N , Klein NP , Baxter RP , Marchant CD , Larussa PS , Barnett ED , Tokars JI , McGeeney BE , Sparks RC , Aukes LL , Jakob K , Coronel S , Sejvar JJ , Slade BA , Edwards KM . Vaccine 2011 29 (46) 8302-8 BACKGROUND: Adverse events occurring after vaccination are routinely reported to the Vaccine Adverse Event Reporting System (VAERS). We studied serious adverse events (SAEs) of a neurologic nature reported after receipt of influenza A (H1N1) 2009 monovalent vaccine during the 2009-2010 influenza season. Investigators in the Clinical Immunization Safety Assessment (CISA) network sought to characterize these SAEs and to assess their possible causal relationship to vaccination. METHODS: Centers for Disease Control and Prevention (CDC) and Food and Drug Administration (FDA) physicians reviewed all SAE reports (as defined by the Code of Federal Regulations, 21CFR section 314.80) after receipt of H1N1 vaccine reported to VAERS between October 1, 2009 and March 31, 2010. Non-fatal SAE reports with neurologic presentation were referred to CISA investigators, who requested and reviewed additional medical records and clinical information as available. CISA investigators assessed the causal relationship between vaccination and the event using modified WHO criteria as defined. RESULTS: 212 VAERS reports of non-fatal serious neurological events were referred for CISA review. Case reports were equally distributed by gender (50.9% female) with an age range of 6 months to 83 years (median 38 years). The most frequent diagnoses reviewed were: Guillain-Barre Syndrome (37.3%), seizures (10.8%), cranial neuropathy (5.7%), and acute disseminated encephalomyelitis (3.8%). Causality assessment resulted in classification of 72 events as "possibly" related (33%), 108 as "unlikely" related (51%), and 20 as "unrelated" (9%) to H1N1 vaccination; none were classified as "probable" or "definite" and 12 were unclassifiable (6%). CONCLUSION: The absence of a specific test to indicate whether a vaccine component contributes to the pathogenesis of an event occurring within a biologically plausible time period makes assessing causality difficult. The development of standardized protocols for providers to use in evaluation of adverse events following immunization, and rapid identification and follow-up of VAERS reports could improve causality assessment. |
Overview of the Clinical Consult Case Review of adverse events following immunization: Clinical Immunization Safety Assessment (CISA) network 2004-2009
Williams SE , Klein NP , Halsey N , Dekker CL , Baxter RP , Marchant CD , Larussa PS , Sparks RC , Tokars JI , Pahud BA , Aukes L , Jakob K , Coronel S , Choi H , Slade BA , Edwards KM . Vaccine 2011 29 (40) 6920-7 BACKGROUND: In 2004 the Clinical Consult Case Review (CCCR) working group was formed within the CDC-funded Clinical Immunization Safety Assessment (CISA) Network to review individual cases of adverse events following immunizations (AEFI). METHODS: Cases were referred by practitioners, health departments, or CDC employees. Vaccine Adverse Event Reporting System (VAERS) searches and literature reviews for similar cases were performed prior to review. After CCCR discussion, AEFI were assessed for a causal relationship with vaccination and recommendations regarding future immunizations were relayed back to the referring physicians. In 2010, surveys were sent to referring physicians to determine the utility and effectiveness of the CCCR service. RESULTS: CISA investigators reviewed 76 cases during 68 conference calls between April 2004 and December 2009. Almost half of the cases (35/76) were neurological in nature. Similar AEFI for the specific vaccines received were discovered for 63 cases through VAERS searches and for 38 cases through PubMed searches. Causality assessment using the modified WHO criteria resulted in classifying 3 cases as definitely related to vaccine administration, 12 as probably related, 16 as possibly related, 18 as unlikely related, 10 as unrelated, and 17 had insufficient information to assign causality. The physician satisfaction survey was returned by 30 (57.7%) of those surveyed and a majority of respondents (93.3%) felt that the CCCR service was useful. CONCLUSIONS: The CCCR provides advice about AEFI to practitioners, assigns potential causality, and contributes to an improved understanding of adverse health events following immunizations. |
Evaluation of immunization rates and safety among children with inborn errors of metabolism
Klein NP , Aukes L , Lee J , Fireman B , Shapira SK , Slade B , Baxter R , Summar M . Pediatrics 2011 127 (5) e1139-46 BACKGROUND: Children with inherited metabolic disorders are a potential high-risk group for vaccine-preventable diseases, yet information regarding immunization rates and vaccine safety within this population is limited. METHODS: Using Northern California Kaiser Permanente's electronic medical record, we identified children with inborn errors of metabolism from 1990 to 2007. We assessed immunization rates among infants with inborn errors of metabolism born at Northern California Kaiser Permanente matched to healthy infants (1 to 20), comparing both vaccines received by 2 years of age and age at vaccination. We assessed postvaccination adverse events among children up to 18 years old with inborn errors of metabolism, separately comparing emergency-department visits and hospitalizations during postvaccine days 0 to 30 (primary) and days 0 to 14 (secondary). RESULTS: Comparing infants with inborn errors of metabolism (n = 77) versus matched control subjects (n = 1540), similar proportions were up to date for vaccines at 2 years of age, and there was no evidence of delay in receipt of recommended vaccines during the first year. Vaccination of children with inborn errors of metabolism (n = 271) was not associated with any significant increase in emergency-department visits or hospitalizations during the 30 days after vaccination. Secondary analyses suggested that there may be increased rates of hospitalizations 2 weeks after vaccination for the sickest 1- to 4-year-old children. CONCLUSIONS: Children with inborn errors of metabolism at Northern California Kaiser Permanente received vaccines on the same immunization schedule as healthy infants. Immunization was not associated with increased risk for serious adverse events during the month after vaccination, providing overall reassurance that routine vaccination of children with inborn errors of metabolism does not result in adverse effects. |
Understanding the role of human variation in vaccine adverse events: the Clinical Immunization Safety Assessment Network.
LaRussa PS , Edwards KM , Dekker CL , Klein NP , Halsey NA , Marchant C , Baxter R , Engler RJ , Kissner J , Slade BA . Pediatrics 2011 127 Suppl 1 S65-73 The Clinical Immunization Safety Assessment (CISA) Network is a collaboration between the Centers for Disease Control and Prevention (CDC) and 6 academic medical centers to provide support for immunization safety assessment and research. The CISA Network was established by the CDC in 2001 with 4 primary goals: (1) develop research protocols for clinical evaluation, diagnosis, and management of adverse events following immunization (AEFI); (2) improve the understanding of AEFI at the individual level, including determining possible genetic and other risk factors for predisposed people and subpopulations at high risk; (3) develop evidence-based algorithms for vaccination of people at risk of serious AEFI; and (4) serve as subject-matter experts for clinical vaccine-safety inquiries. CISA Network investigators bring in-depth clinical, pathophysiologic, and epidemiologic expertise to assessing causal relationships between vaccines and adverse events and to understanding the pathogenesis of AEFI. CISA Network researchers conduct expert reviews of clinically significant adverse events and determine the validity of the recorded diagnoses on the basis of clinical and laboratory criteria. They also conduct special studies to investigate the possible pathogenesis of adverse events, assess relationships between vaccines and adverse events, and maintain a centralized repository for clinical specimens. The CISA Network provides specific clinical guidance to both health care providers who administer vaccines and those who evaluate and treat patients with possible AEFI. The CISA Network plays an important role in providing critical immunization-safety data and expertise to inform vaccine policy-makers. The CISA Network serves as a unique resource for vaccine-safety monitoring efforts conducted at the CDC. |
Comment on the contribution by Souayah et al., "Guillain-Barre syndrome after Gardasil vaccination: data from Vaccine Adverse Event Reporting System 2006-2009"
Slade BA , Gee J , Broder KR , Vellozzi C . Vaccine 2011 29 (5) 865-6 Souayah et al. recently [1] described reports of Guillain–Barré syndrome (GBS) following the quadrivalent human papillomavirus vaccine (HPV4 or Gardasil®) received by the United States Vaccine Adverse Event Reporting System (VAERS) during 2006–2009. The authors accessed the publically available VAERS dataset (http://vaers.hhs.gov), and supplemented it with data from the Food and Drug Administration (FDA) under the Freedom of Information Act, but did not fully account for some of the limitations of VAERS in their interpretation of the data. | As a spontaneous reporting system that is national in scope, VAERS is an important signal-detection system that can generate hypotheses to be tested more rigorously using other data sources [2], [3]. Since reporting is voluntary, VAERS data are subject to reporting biases, such as under-reporting and stimulated reporting (e.g., after the introduction of a new vaccine or when there is publicity around a vaccine). The temporal association of an adverse event with vaccination alone does not prove a causal relationship and VAERS cannot usually assess causality [2], [4]. Furthermore, the information provided on the VAERS report is often incomplete and, without additional review of medical records, it is difficult to verify the reported diagnoses. In a review of HPV4-related VAERS reports through 2008 [5], there were 42 reports of GBS. Of the 21 cases with adequate medical records, only 12 cases (57%) met the Brighton Collaboration case definition of GBS [6]. Although VAERS is a critical frontline system, the Centers for Disease Control and Prevention (CDC) relies on other systems such as the Vaccine Safety Datalink (VSD) to assess any potential associations between vaccination and adverse events, including GBS [7]. |
Peripheral and central auditory dysfunction induced by occupational exposure to organic solvents
Fuente A , Slade MD , Taylor T , Morata TC , Keith RW , Sparer J , Rabinowitz PM . J Occup Environ Med 2009 51 (10) 1202-11 OBJECTIVE: To examine the effects of solvent exposure on hearing function, through an audiological test battery, in a population not occupationally exposed to high levels of noise. METHODS: One hundred ten workers from a coating factory were studied. Jobs at the factory were divided into three different levels of solvent exposure. Hearing status was assessed with a test battery including pure-tone hearing thresholds (0.5-8 kHz), high-frequency hearing thresholds (12 and 16 kHz), and dichotic listening measured through dichotic digits test. Multiple linear regression models were created to explore possible association between solvent exposure and each of the hearing outcomes. RESULTS: Significant associations between solvent exposure and the three hearing outcomes were found. Covariates such as age, gender, race, and ethnicity were also significantly associated with the studied hearing outcomes. CONCLUSIONS: Occupational exposure to solvents may induce both peripheral and central auditory dysfunction. The dichotic digits test seems as a sensible tool to detect central auditory dysfunction associated with solvent exposure. Hearing loss prevention programs may use this tool to monitor hearing in solvent-exposed workers. |
Kawasaki disease after vaccination: reports to the vaccine adverse event reporting system 1990-2007
Hua W , Izurieta HS , Slade B , Belay ED , Haber P , Tiernan R , Woo EJ , Iskander J , Braun MM , Ball R . Pediatr Infect Dis J 2009 28 (11) 943-7 BACKGROUND: Kawasaki disease (KD) is a multisystemic vasculitis primarily affecting children <5 years. A review of RotaTeq (rotavirus vaccine live) clinical trial data revealed higher, though not statistically significantly, KD rates among RotaTeq vaccines than placebo recipients. In June 2007, the RotaTeq label was revised accordingly. OBJECTIVES: To describe and assess KD reported to Vaccine Adverse Event Reporting System (VAERS) for all US licensed vaccines. METHODS: We reviewed all KD reports received by VAERS from 1990 through mid-October 2007. Cases were characterized by age, gender, onset interval, and vaccine type. Proportional reporting ratio (PRR) was used to evaluate KD reporting for each vaccine compared with all others. Reporting rates were calculated using number of doses distributed as denominator. RESULTS: Through October14, 2007, 107 KD reports were received by VAERS: 26 were categorized as classic cases, 19 atypical, 52 possible, and 10 were noncases. Of the 97 cases, 91% were children <5 years. There was no clustering of onset intervals after day 1 postvaccination. Before the RotaTeq label revision, the KD PRR was elevated only for Pediarix (DTaP, hepB, and IPV combined) but the KD reporting rate for Pediarix (0.59/100,000 person-years) was much lower than the background incidence rate (9-19/100,000 person-years) for children <5 years in the United States. After the revision, reporting of KD for RotaTeq was stimulated but the reporting rate for RotaTeq (1.47/100,000 person-years) was still much lower than the background rate. CONCLUSIONS: Our review does not suggest an elevated KD risk for RotaTeq or other vaccines. Continued postmarketing monitoring for KD is ongoing. |
Postlicensure safety surveillance for quadrivalent human papillomavirus recombinant vaccine
Slade BA , Leidel L , Vellozzi C , Woo EJ , Hua W , Sutherland A , Izurieta HS , Ball R , Miller N , Braun MM , Markowitz LE , Iskander J . JAMA 2009 302 (7) 750-7 CONTEXT: In June 2006, the Food and Drug Administration licensed the quadrivalent human papillomavirus (types 6, 11, 16, and 18) recombinant vaccine (qHPV) in the United States for use in females aged 9 to 26 years; the Advisory Committee on Immunization Practices then recommended qHPV for routine vaccination of girls aged 11 to 12 years. OBJECTIVE: To summarize reports to the Vaccine Adverse Event Reporting System (VAERS) following receipt of qHPV. DESIGN, SETTING, AND PARTICIPANTS: Review and describe adverse events following immunization (AEFIs) reported to VAERS, a national, voluntary, passive surveillance system, from June 1, 2006, through December 31, 2008. Additional analyses were performed for some AEFIs in prelicensure trials, those of unusual severity, or those that had received public attention. Statistical data mining, including proportional reporting ratios (PRRs) and empirical Bayesian geometric mean methods, were used to detect disproportionality in reporting. MAIN OUTCOME MEASURES: Numbers of reported AEFIs, reporting rates (reports per 100,000 doses of distributed vaccine or per person-years at risk), and comparisons with expected background rates. RESULTS: VAERS received 12 424 reports of AEFIs following qHPV distribution, a rate of 53.9 reports per 100,000 doses distributed. A total of 772 reports (6.2% of all reports) described serious AEFIs, including 32 reports of death. The reporting rates per 100,000 qHPV doses distributed were 8.2 for syncope; 7.5 for local site reactions; 6.8 for dizziness; 5.0 for nausea; 4.1 for headache; 3.1 for hypersensitivity reactions; 2.6 for urticaria; 0.2 for venous thromboembolic events, autoimmune disorders, and Guillain-Barre syndrome; 0.1 for anaphylaxis and death; 0.04 for transverse myelitis and pancreatitis; and 0.009 for motor neuron disease. Disproportional reporting of syncope and venous thromboembolic events was noted with data mining methods. CONCLUSIONS: Most of the AEFI rates were not greater than the background rates compared with other vaccines, but there was disproportional reporting of syncope and venous thromboembolic events. The significance of these findings must be tempered with the limitations (possible underreporting) of a passive reporting system. |
