Deployment of the National Notifiable Diseases Surveillance System during the 2022-23 mpox outbreak in the United States-Opportunities and challenges with case notifications during public health emergencies
Rainey JJ , Lin XM , Murphy S , Velazquez-Kronen R , Do T , Hughes C , Harris AM , Maitland A , Gundlapalli AV . PLoS One 2024 19 (4) e0300175 Timely case notifications following the introduction of an uncommon pathogen, such as mpox, are critical for understanding disease transmission and for developing and implementing effective mitigation strategies. When Massachusetts public health officials notified the Centers for Disease Control and Prevention (CDC) about a confirmed orthopoxvirus case on May 17, 2023, which was later confirmed as mpox at CDC, mpox was not a nationally notifiable disease. Because existing processes for new data collections through the National Notifiable Disease Surveillance System were not well suited for implementation during emergency responses at the time of the mpox outbreak, several interim notification approaches were established to capture case data. These interim approaches were successful in generating daily case counts, monitoring disease transmission, and identifying high-risk populations. However, the approaches also required several data collection approvals by the federal government and the Council for State and Territorial Epidemiologists, the use of four different case report forms, and the establishment of complex data management and validation processes involving data element mapping and record-level de-duplication steps. We summarize lessons learned from these interim approaches to inform and improve case notifications during future outbreaks. These lessons reinforce CDC's Data Modernization Initiative to work in close collaboration with state, territorial, and local public health departments to strengthen case-based surveillance prior to the next public health emergency. |

MMWR Morb Mortal Wkly Rep 2023 72 (20) 547-552 Monkeypox (mpox) is a serious viral zoonosis endemic in west and central Africa. An unprecedented global outbreak was first detected in May 2022. CDC activated its emergency outbreak response on May 23, 2022, and the outbreak was declared a Public Health Emergency of International Concern on July 23, 2022, by the World Health Organization (WHO),* and a U.S. Public Health Emergency on August 4, 2022, by the U.S. Department of Health and Human Services.(†) A U.S. government response was initiated, and CDC coordinated activities with the White House, the U.S. Department of Health and Human Services, and many other federal, state, and local partners. CDC quickly adapted surveillance systems, diagnostic tests, vaccines, therapeutics, grants, and communication systems originally developed for U.S. smallpox preparedness and other infectious diseases to fit the unique needs of the outbreak. In 1 year, more than 30,000 U.S. mpox cases were reported, more than 140,000 specimens were tested, >1.2 million doses of vaccine were administered, and more than 6,900 patients were treated with tecovirimat, an antiviral medication with activity against orthopoxviruses such as Variola virus and Monkeypox virus. Non-Hispanic Black (Black) and Hispanic or Latino (Hispanic) persons represented 33% and 31% of mpox cases, respectively; 87% of 42 fatal cases occurred in Black persons. Sexual contact among gay, bisexual, and other men who have sex with men (MSM) was rapidly identified as the primary risk for infection, resulting in profound changes in our scientific understanding of mpox clinical presentation, pathogenesis, and transmission dynamics. This report provides an overview of the first year of the response to the U.S. mpox outbreak by CDC, reviews lessons learned to improve response and future readiness, and previews continued mpox response and prevention activities as local viral transmission continues in multiple U.S. jurisdictions (Figure). |
Overview of the 2019 National Health Interview Survey Questionnaire redesign
Zablotsky B , Lessem SE , Gindi RM , Maitland AK , Dahlhamer JM , Blumberg SJ . Am J Public Health 2023 113 (4) e1-e8 Data System. Federal health surveys, like the National Health Interview Survey (NHIS), represent important surveillance mechanisms for collecting timely, representative data that can be used to monitor the health and health care of the US population. Data Collection/Processing. Conducted by the National Center for Health Statistics (NCHS), NHIS uses an address-based, complex clustered sample of housing units, yielding data representative of the civilian noninstitutionalized US population. Survey redesigns that reduce survey length and eliminate proxy reporting may reduce respondent burden and increase participation. Such were goals in 2019, when NCHS implemented a redesigned NHIS questionnaire that also focused on topics most relevant and appropriate for surveillance of child and adult health. Data Analysis/Dissemination. Public-use microdata files and selected health estimates and detailed documentation are released online annually. Public Health Implications. Declining response rates may lead to biased estimates and weaken users' ability to make valid conclusions from the data, hindering public health efforts. The 2019 NHIS questionnaire redesign was associated with improvements in the survey's response rate, declines in respondent burden, and increases in data quality and survey relevancy.

Separating science knowledge from religious belief: Two approaches for reducing the effect of identity on survey responses
Maitland A , Tourangeau R , Sun H . Public Opin Q 2018 82 (1) 34-62 All survey items reflect some conceptual framework that might or might not be accepted by subgroups with certain personal identities. For example, respondents with certain religious identities may reject the scientific framework of questions about the development of life and origins of the universe since there are competing truth claims between religion and science on these topics. Since the late 1970s, the National Science Foundation has sponsored a series of surveys to gauge public attitudes toward and understanding of science and technology. Items that simultaneously measure knowledge and acceptance of two concepts-evolution and the "big bang"-appear to raise measurement problems for a specific subgroup that rejects the premise of the items. This paper focuses on alternative versions of the survey questions that attempt to remove the effect of religious belief on answers to these items. We investigate two approaches for removing this confounding of knowledge and acceptance. One approach is to ask what scientists think rather than what the respondents believe; the other is to remove "hot-button" features of the question likely to trigger conflicts between the religious and scientific views. We also illustrate how psychometric methods (such as confirmatory factor analysis) can help sort out which version of the questions produces the most valid answers. |

BMJ 2014 349 g4164 ![]() OBJECTIVE: To use the rs1229984 variant in the alcohol dehydrogenase 1B gene (ADH1B) as an instrument to investigate the causal role of alcohol in cardiovascular disease. DESIGN: Mendelian randomisation meta-analysis of 56 epidemiological studies. PARTICIPANTS: 261 991 individuals of European descent, including 20 259 coronary heart disease cases and 10 164 stroke events. Data were available on ADH1B rs1229984 variant, alcohol phenotypes, and cardiovascular biomarkers. MAIN OUTCOME MEASURES: Odds ratio for coronary heart disease and stroke associated with the ADH1B variant in all individuals and by categories of alcohol consumption. RESULTS: Carriers of the A-allele of ADH1B rs1229984 consumed 17.2% fewer units of alcohol per week (95% confidence interval 15.6% to 18.9%), had a lower prevalence of binge drinking (odds ratio 0.78 (95% CI 0.73 to 0.84)), and had higher abstention (odds ratio 1.27 (1.21 to 1.34)) than non-carriers. Rs1229984 A-allele carriers had lower systolic blood pressure (-0.88 (-1.19 to -0.56) mm Hg), interleukin-6 levels (-5.2% (-7.8 to -2.4%)), waist circumference (-0.3 (-0.6 to -0.1) cm), and body mass index (-0.17 (-0.24 to -0.10) kg/m(2)). Rs1229984 A-allele carriers had lower odds of coronary heart disease (odds ratio 0.90 (0.84 to 0.96)). The protective association of the ADH1B rs1229984 A-allele variant remained the same across all categories of alcohol consumption (P=0.83 for heterogeneity). Although no association of rs1229984 was identified with the combined subtypes of stroke, carriers of the A-allele had lower odds of ischaemic stroke (odds ratio 0.83 (0.72 to 0.95)). CONCLUSIONS: Individuals with a genetic variant associated with non-drinking and lower alcohol consumption had a more favourable cardiovascular profile and a reduced risk of coronary heart disease than those without the genetic variant. This suggests that reduction of alcohol consumption, even for light to moderate drinkers, is beneficial for cardiovascular health. |
Measuring sexual identity using survey questionnaires: how valid are our measures?
Ridolfo H , Miller K , Maitland A . Sex Res Social Policy 2012 9 (2) 113-124 Patterns of poorer health are observed in numerous groups within the US population. The Healthy People 2020 initiative provides a national framework to improve the health of all people in the USA. One of the four overarching goals of Healthy People 2020 is to achieve healthy equity, eliminate disparities, and improve the health of all groups including, lesbian, gay, bisexual, and transgender (LGBT) people. To achieve this goal for LGBT populations requires that these groups be identified in national health surveys. Sexuality, however, is a complex phenomenon that incorporates numerous, even contradictory, meanings, attitudes, and types of experiences, creating a major challenge in developing a single measure that is both meaningful and comparable across various socio-cultural groups throughout the US population. Without quality data, the picture of LGBT health, as it is portrayed through official statistics, is distorted. We contend that the specific construct of sexual identity (i.e., how individuals identify and conceptualize their own selves) is a key construct necessary for tracking health disparities. In this paper, we assess the validity of sexual identity measures using qualitative data from cognitive interview studies as well as estimates produced from the National Survey of Family Growth and the National Health and Nutrition Examination Survey.

Results of a cross-national structured cognitive interviewing protocol to test measures of disability
Miller K , Mont D , Maitland A , Altman B , Madans J . Qual Quant 2011 45 (4) 801-815 This paper describes the Washington Group project to test a short battery of disability questions developed for national censuses. The study used an unusually structured cognitive test protocol and was administered to a total of 1,290 respondents selected from convenience samples in fifteen countries in Central and South America, Asia and Africa. The test protocol consisted of the six core disability questions followed by questions designed to illustrate: (1) whether core questions were administered with relative ease; (2) how core questions were interpreted by respondents; (3) the factors considered by respondents when forming answers to core questions; and (4) the degree of consistency between responses to core questions and a set of more detailed functioning questions. Additionally, demographic and general health sections allowed for an examination of comparability, specifically, whether test questions performed consistently across all respondents, or if nationality, education, gender or socio-economic status impacted the ways in which respondents interpreted or considered each core question.

Role of self-concept in answering survey questions on complementary and alternative medicine: challenges to and strategies for improving data quality
Willson S , Stussman B , Maitland A , Nahin RL . J Altern Complement Med 2009 15 (12) 1319-25 OBJECTIVES: The aim of this study was to assess the construct validity of survey questions about the use of herbal and other nonvitamin/nonmineral dietary supplements. DESIGN: We conducted one-on-one, in-depth cognitive interviews with 32 respondents to test questions from the complementary and alternative medicine (CAM) supplement for the 2007 National Health Interview Survey. Respondents were sampled purposively according to their use of CAM. Interviewers probed respondents for their understanding of the questions, and analysis was guided by grounded theory, an approach that generates explanations of response error that are closely tied to the empirical data. RESULTS: We found two sources of misinterpretation of CAM questions. First, some respondents did not have any pre-established definition of what constitutes an herbal supplement while others had interpretations that did not match the intended definitions. These problems are common to many survey questions. However, a second finding is that misinterpretation also arose when respondents incorporated notions of self-concept into the act of taking "natural herbs," and answered based on their understanding of this image rather than on actual behavior. CONCLUSIONS: There are several sources of misinterpretation of CAM questions. One of the most important sources is whether or not the respondent has created a concept of self-image that includes the use of herbal supplements. Common questionnaire design techniques such as providing definitions to respondents will not help to eliminate misinterpretation due to self-image. We found that careful question wording that does not evoke definitions of self, combined with visual aids that narrow the focus of the questions, can lead to more accurate answers. |
