Bloodstream Infections With a Novel Nontuberculous Mycobacterium Involving 52 Outpatient Oncology Clinic Patients-Arkansas, 2018.

BACKGROUND: In July 2018, the Arkansas Department of Health (ADH) was notified by hospital A of 3 patients with bloodstream infections (BSIs) with a rapidly growing nontuberculous Mycobacterium (NTM) species; on 5 September 2018, 6 additional BSIs were reported. All were among oncology patients at clinic A. We investigated to identify sources and to prevent further infections. METHODS: ADH performed an onsite investigation at clinic A on 7 September 2018 and reviewed patient charts, obtained environmental samples, and cultured isolates. The isolates were sequenced (whole genome, 16S, rpoB) by the Centers for Disease Control and Prevention to determine species identity and relatedness. RESULTS: By 31 December 2018, 52 of 151 (34%) oncology patients with chemotherapy ports accessed at clinic A during 22 March-12 September 2018 had NTM BSIs. Infected patients received significantly more saline flushes than uninfected patients (P < .001) during the risk period. NTM grew from 6 unused saline flushes compounded by clinic A. The identified species was novel and designated Mycobacterium FVL 201832. Isolates from patients and saline flushes were highly related by whole-genome sequencing, indicating a common source. Clinic A changed to prefilled saline flushes on 12 September as recommended. CONCLUSIONS: Mycobacterium FVL 201832 caused BSIs in oncology clinic patients. Laboratory data allowed investigators to rapidly link infections to contaminated saline flushes; cooperation between multiple institutions resulted in timely outbreak resolution. New state policies being considered because of this outbreak include adding extrapulmonary NTM to ADH's reportable disease list and providing more oversight to outpatient oncology clinics.

High COVID-19 Attack Rate Among Attendees at Events at a Church - Arkansas, March 2020.

On March 16, 2020, the day that national social distancing guidelines were released (1), the Arkansas Department of Health (ADH) was notified of two cases of coronavirus disease 2019 (COVID-19) from a rural county of approximately 25,000 persons; these cases were the first identified in this county. The two cases occurred in a husband and wife; the husband is the pastor at a local church (church A). The couple (the index cases) attended church-related events during March 6-8, and developed nonspecific respiratory symptoms and fever on March 10 (wife) and 11 (husband). Before his symptoms had developed, the husband attended a Bible study group on March 11. Including the index cases, 35 confirmed COVID-19 cases occurred among 92 (38%) persons who attended events held at church A during March 6-11; three patients died. The age-specific attack rates among persons aged ≤18 years, 19-64 years, and ≥65 years were 6.3%, 59.4%, and 50.0%, respectively. During contact tracing, at least 26 additional persons with confirmed COVID-19 cases were identified among community members who reported contact with church A attendees and likely were infected by them; one of the additional persons was hospitalized and subsequently died. This outbreak highlights the potential for widespread transmission of SARS-CoV-2, the virus that causes COVID-19, both at group gatherings during church events and within the broader community. These findings underscore the opportunity for faith-based organizations to prevent COVID-19 by following local authorities' guidance and the U.S. Government's Guidelines: Opening Up America Again (2) regarding modification of activities to prevent virus transmission during the COVID-19 pandemic.

Notes from the Field: Cluster of Tuberculosis Cases Among Marshallese Persons Residing in Arkansas - 2014-2015.

During early September 2014, the Arkansas Department of Health identified an increased number of tuberculosis (TB) cases among a unique population in a well-circumscribed geographical area in northwest Arkansas. The Compact of Free Association Act of 1985 (Public Law 99-239, amended in 2003 by Public Law 108-188) established the Republic of the Marshall Islands (RMI) as an independent nation, and persons from the RMI can travel freely (with valid RMI passport) to and from the United States as nonimmigrants without visas (1). Marshallese started settling in northwest Arkansas during the early 1990s because of employment and educational opportunities (2). According to the 2010 Census, an estimated 4,300 Marshallese resided in Arkansas (2), mostly within one county which ranked 6th in the United States for counties with the highest percentage of Native Hawaiians and Other Pacific Islanders (3). It is estimated that this number has been growing steadily each year since the 2010 Census; however, obtaining an accurate count is difficult. The RMI is a TB high-incidence country, with a case-rate of 212.7 per 100,000 persons for 2014, whereas the case-rate was 3.1 per 100,000 persons in Arkansas and 2.9 per 100,000 persons in the United States (4,5). Screening for either active TB or latent TB infection (LTBI) is not required for Marshallese entry to the United States (1).

Mobilizing a Statewide Network to Provide Ebola Education and Support.

BACKGROUND: Healthcare providers require the latest information and procedures when a public health emergency arises. During the fall of 2014, when the Ebola virus was first identified in a patient in the United States, education about Ebola virus disease (EVD) and procedures for its identification and control needed widespread and immediate dissemination to healthcare providers. In addition, there was a need to allay fears and reassure the public and providers that a process was in place to manage Ebola should it arrive in Arkansas. The state health department engaged multiple interest groups and provided a variety of educational and management activities. The Arkansas Department of Health and the only academic medical center in the state began offering time-consuming, one-on-one education over the phone, which reached too few providers. A solution was needed to educate many providers across the state in the protocols for identification, isolation, and management of patients with EVD. In response, the Arkansas Department of Health and the University of Arkansas for Medical Sciences leveraged the interactive video and Webinar capabilities of the state's telemedicine network to educate both providers and the public of this public health emergency. MATERIALS AND METHODS: Six interactive video events were staged over 5 days in October 2014. RESULTS: In six events, 82 individual healthcare facilities (67 of which were hospitals) and 378 providers attended via the Webinar option, whereas 323 healthcare professionals received continuing education credits. CONCLUSIONS: A statewide videoconferencing infrastructure can be successfully mobilized to provide timely public health education and communication to healthcare providers and the public in multiple disciplines and practice settings.

Multiple-serotype salmonella outbreaks in two state prisons--Arkansas, August 2012.

In August 2012, the Arkansas Department of Health (ADH) was notified of gastrointestinal illness outbreaks in two Arkansas state prisons. ADH investigated the outbreaks and conducted case-control studies to identify the source of the illnesses. This report describes the results of these investigations, which identified 528 persons with onset of diarrhea during August 2-18, 2012. Results from the prison A investigation identified chicken salad as the most likely vehicle. At prison B, person-to-person transmission and contamination of multiple foods likely contributed to illness. Analysis of stool specimens from inmates identified eight serotypes and 15 pulsed-field gel electrophoresis (PFGE) patterns of Salmonella. Isolates of Salmonella from eggs produced at prison B matched two outbreak patterns. An additional 69 inmates were positive by culture but were not interviewed or did not report diarrhea, making the total case count 597. Sanitarians identified problems with food preparation, hand washing, and food safety training. ADH tested inmate kitchen workers, excluded infected inmates from work, and provided food safety training. Prison kitchen staff should follow guidelines consistent with state regulations for safe food preparation and pass sanitarian inspection.

Collaborative medicine: weaving the microbiology laboratory into clinical practice.

The case presentation of K kingae osteoarthritis used here illustrates technological and procedural advances in microbiological diagnostics and communication. These activities are active in the sense that molecular developments are driving rapid diagnoses and that rapidly communicated results have the potential to drive better decision making and care. The hypothesis that a newer, less passive microbiology ("interventional microbiology") can improve care and reduce costs deserves testing in several institutions. If confirmed, rapid implementation of diagnostic pathways into standard practice, point-of-care molecular diagnostics, enhancement of traditional culture methods, and effective communication in emergency departments and hospitals are warranted and should be a focus for quality improvement.

Treatment for tobacco dependence for rural, lower-income smokers: outcomes, predictors, and measurement considerations.

PURPOSE: Outcomes from a statewide program that delivered evidence-based, intensive treatment for tobacco dependence to a rural population of lower socioeconomic status (SES) were evaluated. Factors that predicted success and measurement considerations were examined. DESIGN AND ANALYSES: Data were collected at intake, at all treatment sessions, and at 3- and 12-months posttreatment. Abstinence rates were calculated using complete-case analysis and intention-to-treat analysis, and they were estimated for all participants. Logistic regression was used to evaluate the predictive significance of demographic and clinical factors. SETTING: Twenty health care sites across Arkansas. PARTICIPANTS: A total of 2,350 predominantly rural, lower SES, Arkansas residents. INTERVENTION: Evidence-based, six-session, multi-component cognitive-behavioral therapy with relapse prevention. RESULTS: The estimated percent abstinent was 26.47% at 3-months and 21.73% at 12-months posttreatment; 51.02% of patients completed treatment and demonstrated markedly higher quit rates. Although numerous factors predicted outcomes at different points, self-efficacy and dependence levels at intake were robust predictors across time and methods of calculating outcomes. Sex, partner smoking status, and educational level were significant predictors of long-term abstinence. CONCLUSIONS: This study demonstrates that intensive, evidence-based treatment for tobacco dependence can be successfully delivered in a statewide program and can yield long-term outcomes that approximate those seen in more controlled settings. Overall sample estimates may be more appropriate for the assessment of outcomes in this context.

Making hospital grounds smoke-free: a case study of Arkansas Act 134 of 2005.

The impact of tobacco use and environmental tobacco smoke (ETS) has been well documented. Many policies have been implemented to curb tobacco use and to reduce exposure to ETS. The purpose of this article is to describe the development and passage of Arkansas Act 134 of 2005, the first state law to prohibit the use of tobacco products on the grounds of all nonfederal community (nonpsychiatric) hospital facilities in the state. Efforts to bring this and other tobacco control policies to the attention of policy makers will be discussed in the context of several agenda-setting strategies. The strategy used by stakeholders in Arkansas to bring out Act 134 as well as the other agenda-setting strategies described in the article provide insight into the ways other states and communities seeking to adopt smoking bans and related public health policies can bring such policies to the attention of policy makers.

Mumps in a highly vaccinated Marshallese community in Arkansas, USA: an outbreak report.

BACKGROUND: During 2000-15, Arkansas Department of Health, Little Rock, AR, USA, investigated between one and six cases of mumps each year. From Aug 5, 2016, to Aug 5, 2017, the department received notification of more than 4000 suspected mumps cases in the second largest outbreak in the USA in the past 30 years. METHODS: Arkansas Department of Health investigated all reported cases of mumps to ascertain exposure, travel, and vaccination histories and identify close contacts. Cases were classified as confirmed if the patient had laboratory confirmation of mumps virus or probable if they had clinical symptoms and either a positive serological test or a known epidemiological link to a confirmed case. FINDINGS: 2954 cases of mumps related to the outbreak were identified during the outbreak period: 1665 (56%) were laboratory confirmed, 1676 (57%) were in children aged 5-17 years, and 1692 (57%) were in Marshallese people. Among the 1676 school-aged cases, 1536 (92%) had previously received at least two doses of a vaccine containing the mumps virus. Although 19 cases of orchitis were reported, severe complications were not identified. Unusual occurrences, such as recurrent parotitis and prolonged viral shedding, were observed mostly in Marshallese individuals. Viral samples were characterised as genotype G. INTERPRETATION: This large-scale outbreak, primarily affecting a marginalised community with intense household crowding, highlights the need for coordinated, interdisciplinary, and non-traditional outbreak responses. This outbreak raises questions about mumps vaccine effectiveness and potential waning immunity. FUNDING: Council of State and Territorial Epidemiologists and US Centers for Disease Control and Prevention.

Impact of addition of philosophical exemptions on childhood immunization rates.

BACKGROUND: Although incidence of vaccine-preventable diseases has decreased, states' school immunization requirements are increasingly challenged. Subsequent to a federal court ruling affecting religious immunization exemptions to school requirements, new legislation made philosophical immunization exemptions available in Arkansas in 2003-2004. This retrospective study conducted in 2006 describes the impact of philosophical exemption legislation in Arkansas. METHODS: Arkansas Division of Health data on immunization exemptions granted were linked to Department of Education data for all school attendees (grades K through 12) during 2 school years before the legislation (2001-2002 and 2002-2003 [Years 1 and 2, respectively]) and 2 years after philosophical exemptions were available (2003-2004 and 2004-2005 [Years 3 and 4, respectively]). Changes in numbers, types, and geographic distribution of exemptions granted are described. RESULTS: The total number of exemptions granted increased by 23% (529 to 651) from Year 1 to 2; by 17% (total 764) from Year 2 to 3 after philosophical exemptions were allowed; and by another 50% from Year 3 to 4 (total 1145). Nonmedical exemptions accounted for 79% of exemptions granted in Years 1 and 2, 92% in Year 3, and 95% in Year 4. Importantly, nonmedical exemptions clustered geographically, suggesting concentrated risks for vaccine-preventable diseases in Arkansas communities. CONCLUSIONS: Legislation allowing philosophical exemptions from school immunization requirements was linked to increased numbers of parents claiming nonmedical exemptions, potentially causing an increase in risk for vaccine-preventable diseases. Continued education and dialogue are needed to explore the balance between individual rights and the public's health.

Impact of a smoke-free hospital campus policy on employee and consumer behavior.

OBJECTIVE: Although smoke-free hospital campuses can provide a strong health message and protect patients, they are few in number due to employee retention and public relations concerns. We evaluated the effects of implementing a clean air policy on employee attitudes, recruitment, and retention; hospital utilization; and consumer satisfaction in 2003 through 2005. METHODS: We conducted research at a university hospital campus with supplemental data from an affiliated hospital campus. Our evaluation included (1) measurement of employee attitudes during the year before and year after policy implementation using a cross-sectional, anonymous survey; (2) focus group discussions held with supervisors and security personnel; and (3) key informant interviews conducted with administrators. Secondary analysis included review of employment records and exit interviews, and monitoring of hospital utilization and patient satisfaction data. RESULTS: Employee attitudes toward the policy were supportive (83.3%) at both institutions and increased significantly (89.8%) at post-test at the university hospital campus. Qualitatively, administrator and supervisor attitudes were similarly favorable. There was no evidence on either campus of an increase in employee separations or a decrease in new hiring after the policy was implemented. On neither campus was there a change in bed occupancy or mean daily census. Standard measures of consumer satisfaction were also unchanged at both sites. CONCLUSION: A campus-wide smoke-free policy had no detrimental effect on measures of employee or consumer attitudes or behaviors.

Variation in Tularemia Clinical Manifestations-Arkansas, 2009-2013.

BACKGROUND: Francisella tularensis, although naturally occurring in Arkansas, is also a Tier 1 select agent and potential bioterrorism threat. As such, tularemia is nationally notifiable and mandatorily reported to the Arkansas Department of Health. We examined demographic and clinical characteristics among reported cases and outcomes to improve understanding of the epidemiology of tularemia in Arkansas. METHODS: Surveillance records on all tularemia cases investigated during 2009-2013 were reviewed. RESULTS: The analytic dataset was assembled from 284 tularemia reports, yielding 138 probable and confirmed tularemia cases during 2009-2013. Arthropod bite was identified in 77% of cases. Of 7 recognized tularemia manifestations, the typhoidal form was reported in 47% of cases, approximately double the proportion of the more classic manifestation, lymphadenopathy. Overall, 41% of patients were hospitalized; 3% died. The typhoidal form appeared to be more severe, accounting for the majority of sepsis and meningitis cases, hospitalizations, and deaths. Among patients with available antibiotic data, 88% received doxycycline and 12% received gentamicin. CONCLUSIONS: Contrary to expectation, lymphadenopathy was not the most common manifestation observed in our registry. Instead, our patients were more likely to report only generalized typhoidal symptoms. Using lymphadenopathy as a primary symptom to initiate tularemia testing may be an insensitive diagnostic strategy and result in unrecognized cases. In endemic areas such as Arkansas, suspicion of tularemia should be high, especially during tick season. Outreach to clinicians describing the full range of presenting symptoms may help address misperceptions about tularemia.

Comparison of Office-Based Versus Outsourced Immunization Recall Services.

OBJECTIVE: Given poor use of recall in primary care practices, we compared outsourced versus office-based recall systems. STUDY DESIGN: From 2011 to 2013, we enrolled 87 individual Arkansas providers in distinct practices treating their own patients <24 months of age which were randomized to usual care (A), office-based (B), or outsourced (C) recall groups. RESULTS: At the end of study, recall activity was 19.4%, 55.0%, and 92.6% for Groups A, B, and C, respectively (B and C vs A: P < .001). Only 68 Group B patients were identified as needing immunizations versus 826 in Group C. The majority of successful contacts were made through mobile phone (41.3%) or text message (32.6%). The total cost per practice per week was significantly lower for Group C versus Group B ($39.50 and $53.00, respectively; P = .004). CONCLUSIONS: With limited electronic health record use, an outsourced recall system is more sustainable and less costly than an office-based system.

Electronic Nicotine Delivery Systems and Smoking Cessation in Arkansas, 2014.

OBJECTIVES: As of October 2015, evidence needed to make a recommendation about the use of electronic nicotine delivery systems (ENDS) for smoking cessation was limited. We used the 2014 Arkansas Behavioral Risk Factor Surveillance System with additional state-specific questions to determine the prevalence of ENDS use, the impact of ENDS use on smoking cessation, and beliefs about ENDS use in Arkansas. Our objectives were to determine if (1) ENDS use was associated with lower odds of quitting smoking, (2) ENDS users believed that ENDS use was not harmful to their health, and (3) ENDS users believed that switching to ENDS reduced their tobacco-related health risks. METHODS: We conducted a cross-sectional study of 4465 respondents to the Arkansas Behavioral Risk Factor Surveillance System and used weighted analyses to account for the complex survey design. We used a subset of records formed by (1) formers smokers who quitted smoking in the last 5 years and (2) current smokers to assess the odds of quitting. RESULTS: In 2014, 6.1% (95% confidence interval [CI], 5.0%-7.4%) of Arkansas adults were currently using ENDS. Of the 1083 participants who were current smokers or had quit smoking within the past 5 years, 515 (54.1%) had used ENDS. Of the 515 ENDS users, 404 (80.3%) had continued smoking. ENDS use was significantly associated with reduced odds of quitting smoking (weighted odds ratio = 0.53; 95% CI, 0.34-0.83). Although 2437 of 3808 participants (62.5%) believed that it was harmful for nonsmokers to start using ENDS and 1793 of 3658 participants (47.0%) believed that switching to ENDS did not reduce tobacco-related health risks, only 80 of 165 (41.3%) and 50 of 168 (33.9%) ENDS users shared these same respective beliefs. CONCLUSIONS: Most smokers who indicated smoking in the past 5 years and who tried ENDS did not stop smoking. ENDS use was inversely associated with smoking cessation. Tobacco cessation programs should tell cigarette smokers that ENDS use may not help them quit smoking.
