1 Jean Beinemann RN, Terri Boxrucker RN, and LT Dee Dee Downie MPH Outline The disease The outbreak The response The conclusions May 18, 2014 Wisconsin Public Health Association Annual Meeting Tuberculosis (TB) Mycobacterium tuberculosis Transmitted in air Usually affects the lungs, but also other sites Common symptoms: cough, fever, weight loss Medical Evaluation for TB Medical history (symptoms, exposure, past treatment, risk factors) Physical examination (overall condition) Test for TB infection i (TST and IGRAs) Chest radiograph (lesions suggest but not confirm) Bacteriologic examination (specimen collection, smear, culture identification, drug susceptibility) Chest Radiograph with Lower Lobe Cavity 1

2 Knowing the Difference Between Infection and Disease Takes Time Blood and skin tests only tell us if the person is infected. Genetic tests (PCR), if positive, ii mean that the person has TB. But a negative does NOT mean that the person doesn t have TB. Culture is the only gold standard for knowing if someone has TB; culture can take up to eight weeks. TB is Preventable and Curable Best prevention is to identify and treat active TB cases early, before transmission to others Once transmission occurs, detecting and treating LTBI helps prevent new cases of active TB Contagiousness greatly decreased within two weeks after start of effective treatment for TB disease 7 TB Morbidity ( ) TB in Wisconsin About 70 cases per year X 10 years Increasing percent of cases are foreign born or children of foreign born parents 2013: 50 cases, 78% in foreign born or children of foreign born Between 3 and 10% of cases each year are multi drugresistant (MDR); all in people of Asian descent Source: CDC, / tb/ statistics/ reports/ 2011/, WI Division of Public Health, CDC, Trends in TB United States, 2012, MMWR, March 22, (2012 data provisional) 10 Multidrug resistant Tuberculosis (MDR TB) Definition: drug resistance to at least isoniazid (INH) and Rifampin (RIF). Normal treatment for TB is 6 9 months but for MDR TB, treatment is for months post sputum culture conversion and usually totals months, plus the recommended 2 year follow up monitoring. Standards in MDR TB Treatment MDR TB expertise is needed to manage each case. More frequent laboratory collection and analysis is needed than with non drug resistant TB (second line drug susceptibilities, therapeutic drug monitoring, longer sputum collection is needed to assess for treatment failure). All treatment is individually based (medications, treatment response, monitoring and duration).

3 The Global Burden of TB 2012 All forms of TB HIV-associated TB Multidrug-resistant TB MDR TB in the United States MDR TB cases are 1.3% of all cases in the U.S. between (638 cases). States with the highest number of MDR TB cases are: California (162), New York (84), Texas (74) New Jersey (45). MDR TB cases are 14% US born and 86% Foreignborn.

7 Effective Communication Externally and Internally Public Information Officer crafts messages. Schedule Media Conferences. Use Joint Information System for community messages. Keep DHS and County Administration Updated. Emergency Manager can serve as an effective liaison. Schedule regular staff updates. Allow all staff a process to be heard. Step Back and Look at the Big Picture Understand that multiple internal and community providers are involved and have various levels of experience, expertise, expectations and roles. Everything isn t always Black or White. There are different approaches and treatment recommendations related to MDR TB. Keep your eye on the goal..early identification and successful treatment of cases with elimination of spread of disease. TB Elimination! Involve Finance Early in Process Time tracking and expense documentation critical. Projections for JFC request was based on past experience and expected # of cases. Having TB Dispensary Program in place was very helpful. Clients were largely uncertain regarding their health care coverage and struggled with Medicaid Application Process and understanding insurance statements. Funding does not magically appear! Logistical Lessons Technology Expand cell phones with texting availability, dictation use Post all meeting schedules and updates Streamline and centralize medication supply Two person team to manage medication refills and bubble packing. Use of Communication Logs for DOT workers Assure pre and post exposure testing of workers Develop consistent documentation standards Bring in support staff to act as runners, DOT workers, etc. Our Greatest Assets Strong support of elected officials and leadership Dedicated staff and community partners Staff with years of TB knowledge including previous experience with MDR TB and previous emergency preparedness training Trust within the Hmong Community Overall compliance of affected clients Best Approach: Prevent Outbreaks Engage the Hmong community in testing Engage the whole medical community in early identification of disease Early diagnosis i and treatment: relies on healthcare h provider awareness of possibility of TB May be enhanced if patient can identify risk to provider Targeted testing of high risk persons Education for clinicians and persons at risk 7
