TB Notes 32017
Notes from the Director
This past spring, Division of Tuberculosis Elimination (DTBE) staff have been involved in a variety of events. DTBE hosted a TB Expert Network Conference in late April with the CDC-funded TB Regional Training and Medical Consultation Centers (RTMCCs) and the National Jewish Medical Research Center. This conference served as a forum for TB experts to discuss challenging or complicated cases. The conference focused on clinical conundrums in the HIV-TB co-infected patient.
The Tuberculosis Trials Consortium (TBTC) held their 39th Semi-Annual Meeting in May in Atlanta. The meeting highlighted research on the diagnosis, clinical management, and treatment of latent TB infection (LTBI) and TB disease, as well as an exciting collaboration with the Tuberculosis Epidemiologic Studies Consortium (TBESC) to study a 6-week LTBI treatment regimen. The 8th annual Tuberculosis Epidemiologic Studies Consortium (TBESC) meeting was held May 18-19 in Atlanta. The meeting highlighted current and planned TBESC studies that encompass elements of LTBI testing, treatment, program evaluation, and opportunities to increase uptake of testing and treatment, such as working with community providers. In addition, DTBE staff traveled to California to meet with the California Tuberculosis Elimination Advisory Committee to assist in the development of a clear, focused TB prevention communication strategy.
Congratulations to the Surveillance for Tuberculosis Elimination Management System (STEMS) Development Team, winners of the June 2017 National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP) Director’s Recognition Award! DTBE developed STEMS to streamline LTBI patient management. The real-time data can be used to graphically demonstrate a local program’s progress in identifying persons in their jurisdiction who need to be screened for LTBI, evaluating them completely, beginning treatment for those with LTBI, and documenting completion of treatment. STEMS was officially released on January 13, 2017.
As we enter the last half of the year, I continue to be inspired by your dedication to the very important work you are doing every day in our efforts to eliminate TB. I hope all of you have a safe, enjoyable, and productive summer.

Retirement of Wanda Walton, PhD, MEd— Branch Chief for the Communications, Education, and Behavioral Studies Branch (CEBSB) in the Division of Tuberculosis Elimination (DTBE)
Wanda Walton, PhD, MEd— Branch Chief of CEBSB in DTBE, will be retiring on July 31, 2017. In 1989, Dr. Walton joined the U.S. Centers for Disease Control and Prevention’s (CDC) Division of Tuberculosis Control as the first TB/HIV Health Education Specialist. Charged with the task of developing training materials for healthcare providers, she soon recognized the need to develop accurate and up-to-date materials for patients, their families, and communities, as well. Upon stepping into the role of Chief of the Communications, Education, and Behavioral Studies Branch (CEBSB) within CDC’s Division of Tuberculosis Elimination (DTBE) in 1999, she assembled a team of Health Education Specialists, Health Communications Specialists, and Behavioral Scientists. This team has worked to develop a comprehensive TB-specific website that allows providers and patients to easily access TB information 24 hours a day in both English and Spanish. They also conduct behavioral studies to inform improved program practice; develop culturally and linguistically appropriate patient education materials; create and sustain the TB Education and Training Network; and develop continuing education training materials, online training courses, and communication materials for a wide variety of health care providers.
In addition to her work focusing on the elimination of TB in the United States, Dr. Walton has provided training and technical consultation to assist countries around the world to strengthen their TB care and prevention capacities. Some examples include: China, where she worked alongside TB program staff to adapt the Self-Study Modules on Tuberculosis to their program; the Philippines, Thailand, India, and Ethiopia where she facilitated “Training of Trainers” courses; Vietnam, Nepal, Philippines, and Bangladesh where she reviewed staff training needs and programs; and Peru, Estonia, and Latvia, where she contributed to MDR-TB training and education.
It is simply not possible to quantify Dr. Walton’s contributions to ending TB. Her visionary approach and decisions are often mirrored by other nations. For more than 25 years, her talent, enthusiasm, and commitment to creating and sharing knowledge and resources, and to building capacity from within has been preparing and inspiring countless educators around the world to do the same. As a result, her efforts have strengthened TB prevention and control from frontlines to boardrooms, all over the world. Dr. Walton’s service and dedication to improve global TB literacy have been greatly appreciated. In retirement, she plans to travel, perfect her pound cake and cornbread recipes, and spend more time with family and friends after moving to Birmingham, AL.

Tuberculosis Laboratory Aggregate Report
DTBE Laboratory Capacity Team (LCT) recently released the Fourth Edition of the Tuberculosis Laboratory Aggregate Report pdf icon[PDF – 4 MB]. Data detailed in the report are self-reported by public health laboratories supported, in part, by the CDC TB Elimination Cooperative Agreement. The report includes a comparison of public health laboratory tuberculosis aggregate workload data for calendar years 2012 to 2015, and six-year trends (2010–2015) for turnaround time (TAT). Peer data is provided for comparison and serves as a guide to define a laboratory’s TAT goals using national averages and trends.
Diagnostic Mycobacteriology Workshop
During the week of March 28, not only did Atlanta’s I-85 bridge collapse, but the DTBE Laboratory Branch also hosted their annual Diagnostic Mycobacteriology Workshop at the CDC Roybal Campus. Twenty laboratorians from 19 U.S. states and Mexico participated in this four-day course that included topics on laboratory risk assessment, proper use of a biosafety cabinet, specimen processing, approaches for investigating potential false-positive and false-negative results, mycobacteriology test methods including drug susceptibility testing, laboratory performance metrics, test validation, whole genome sequencing, and TB epidemiology. Participants performed real-time Polymerase Chain Reaction (PCR) during a hands-on laboratory session, and contributed to individual and group case study exercises. Participants also enjoyed a presentation titled “Beyond the Laboratory Walls: Enhancing Your Integrated System,” presented by Jessica Gentry, Tuberculosis Laboratory Supervisor at the Indiana State Department of Health. Jessica spoke about the importance of building relationships with partners within a state laboratory network, TB program, or with external laboratories. She provided real life examples of how collaboration could benefit various parties and presented activities laboratorians could participate in to engage these partners. The next Diagnostic Mycobacteriology Workshop will be held in April 2018 with applications due in late 2017.

Economic evaluation of investigating and following persons exposed to a person with extensively -drug resistant tuberculosis in the United States
Contact investigations are an essential component of TB prevention and control in the United States; however, information about their cost is limited. In April 2015, a person with extensively drug-resistant tuberculosis (XDR TB) arrived in the United States from a high-incidence country, stimulating an evaluation of 81 individuals (contacts), and periodic examinations of those with latent TB infection (LTBI). We conducted an economic evaluation to estimate the cost of the large-scale contact investigation for the sixteen sites involved, including fifteen states and one county. The reported data represented 55% of the costs, with 45% of data estimated.
Preliminary cost calculations in 2016 US dollars were determined according to a three-step micro-costing framework: identification of components, measurement of units consumed, and monetary valuation of each unit adjusted for cost-of-living. Representatives from eight sites participated in data collection through semi-structured telephone interviews. We estimated missing data for the other sites using reported data from other sites or publicly available sources. We added contacts’ productivity losses and out-of-pocket costs for a societal perspective, and an estimate of the cost of treating the index case from a published source.
Twenty-five contacts tested positive for LTBI. Seven contacts started and five finished treatment for LTBI susceptible to first line drugs. Contacts were tested using TB skin tests (TSTs) and Interferon-gamma release assays (IGRAs) in equal proportion, with no significant difference in the proportions of positive tests. From a healthcare sector perspective, this multistate contact investigation cost $84,400, with personnel costs representing 77%, and the cost of initial testing representing 19%. Per-site estimates ranged from $100 to $28,000, with per contact costs from $50 to $2,300. From a societal perspective, the total costs were $116,000, ranging from $100 to $36,000 for individual sites, with per-contact costs from $200 to $3,500. Adding the cost of index case air transport and treatment, total cumulative costs were $614,000 and $836,000 from the healthcare sector and societal perspectives respectively. Results were robust to assumptions using all IGRA tests (1% difference), and exclusion of out-of-pocket costs (6% difference). The preliminary results from this study could facilitate planning for future contact investigations, and may stimulate the development of a database that compiles costs of contact investigations.
