Infectious disease surveillance and modelling across geographic frontiers and scientific specialties
Khan K , McNabb SJ , Memish ZA , Eckhardt R , Hu W , Kossowsky D , Sears J , Arino J , Johansson A , Barbeschi M , McCloskey B , Henry B , Cetron M , Brownstein JS . Lancet Infect Dis 2012 12 (3) 222-30 Infectious disease surveillance for mass gatherings (MGs) can be directed locally and globally; however, epidemic intelligence from these two levels is not well integrated. Modelling activities related to MGs have historically focused on crowd behaviours around MG focal points and their relation to the safety of attendees. The integration of developments in internet-based global infectious disease surveillance, transportation modelling of populations travelling to and from MGs, mobile phone technology for surveillance during MGs, metapopulation epidemic modelling, and crowd behaviour modelling is important for progress in MG health. Integration of surveillance across geographic frontiers and modelling across scientific specialties could produce the first real-time risk monitoring and assessment platform that could strengthen awareness of global infectious disease threats before, during, and immediately after MGs. An integrated platform of this kind could help identify infectious disease threats of international concern at the earliest stages possible; provide insights into which diseases are most likely to spread into the MG; help with anticipatory surveillance at the MG; enable mathematical modelling to predict the spread of infectious diseases to and from MGs; simulate the effect of public health interventions aimed at different local and global levels; serve as a foundation for scientific research and innovation in MG health; and strengthen engagement between the scientific community and stakeholders at local, national, and global levels. |
Pulmonary impairment after tuberculosis and its contribution to TB burden
Pasipanodya JG , McNabb SJ , Hilsenrath P , Bae S , Lykens K , Vecino E , Munguia G , Miller TL , Drewyer G , Weis SE . BMC Public Health 2010 10 (1) 259 BACKGROUND: The health impacts of pulmonary impairment after tuberculosis (TB) treatment have not been included in assessments of TB burden. Therefore, previous global and national TB burden estimates do not reflect the full consequences of surviving TB. We assessed the burden of TB including pulmonary impairment after tuberculosis in Tarrant County, Texas using Disability-adjusted Life Years (DALYs) METHODS: TB burden was calculated for all culture-confirmed TB patients treated at Tarrant County Public Health between January 2005 and December 2006 using identical methods and life tables as the Global Burden of Disease Study. Years of life-lost were calculated as the difference between life expectancy using standardized life tables and age-at-death from TB. Years lived-with-disability were calculated from age and gender-specific TB disease incidence using published disability weights. Non-fatal health impacts of TB were divided into years lived-with-disability-acute and years lived-with-disability-chronic. Years lived-with-disability-acute was defined as TB burden resulting from illness prior to completion of treatment including the burden from treatment-related side effects. Years lived-with-disability-chronic was defined as TB burden from disability resulting from pulmonary impairment after tuberculosis. RESULTS: There were 224 TB cases in the time period, of these 177 were culture confirmed. These 177 subjects lost a total of 1189 DALYs. Of these 1189 DALYs 23% were from years of life-lost, 2% were from years lived-with-disability-acute and 75% were from years lived-with-disability-chronic. CONCLUSIONS: Our findings demonstrate that the disease burden from TB is greater than previously estimated. Pulmonary impairment after tuberculosis was responsible for the majority of the burden. These data demonstrate that successful TB control efforts may reduce the health burden more than previously recognized. |
Capacity of public health surveillance to comply with revised international health regulations, USA
Armstrong KE , McNabb SJ , Ferland LD , Stephens T , Muldoon A , Fernandez JA , Ostroff S . Emerg Infect Dis 2010 16 (5) 804-8 Public health surveillance is essential for detecting and responding to infectious diseases and necessary for compliance with the revised International Health Regulations (IHR) 2005. To assess reporting capacities and compliance with IHR of all 50 states and Washington, DC, we sent a questionnaire to respective epidemiologists; 47 of 51 responded. Overall reporting capacity was high. Eighty-one percent of respondents reported being able to transmit notifications about unknown or unexpected events to the Centers for Disease Control and Prevention (CDC) daily. Additionally, 80% of respondents reported use of a risk assessment tool to determine whether CDC should be notified of possible public health emergencies. These findings suggest that most states have systems in place to ensure compliance with IHR. However, full state-level compliance will require additional efforts. |
Evaluation of program performance and expenditures in a report of performance measures (RPM) via a case study of two Florida county tuberculosis programs
Phillips VL , Teweldemedhin B , Ahmedov S , Cobb J , McNabb SJ . Eval Program Plann 2010 33 (4) 373-8 Health Department (HD) managers at both state and local levels are in desperate need of tools to assist in monitoring and evaluating programs. The purpose of this study is to assess the feasibility and utility of linking program performance scores and expenditures into a Report of Performance Measures (RPM). We analyzed secondary data on performance indicators, selected by HD staff, and expenditures, related to six surveillance activities, from two, similar, high-incidence, tuberculosis (TB) programs in Florida from 2002 to 2003. We compared the findings between the county HDs as an illustration of basic cost-effectiveness benchmarking, based on the cost-effectiveness grid. Data included here provide examples of: (1) two instances in which one county was operating relatively inefficiently compared to the other; (2) two instances in which performance and expenditures were similar for the counties; and (3) two instances in which one county spent more for higher performance scores than the other. These data illustrate how the RPM can be used to facilitate benchmarking, a basic evaluation tool. They also demonstrate ways to identify potential operational inefficiencies in a single time period and ultimately over time. It is thus likely to be a feasible and useful management tool. |
The societal cost of tuberculosis: Tarrant County, Texas, 2002
Miller TL , McNabb SJ , Hilsenrath P , Pasipanodya J , Drewyer G , Weis SE . Ann Epidemiol 2010 20 (1) 1-7 PURPOSE: Cost analyses of tuberculosis (TB) in the United States have not included elements that may be prevented if TB were prevented, such as losses associated with TB-related disability, personal and other costs to society. Unmeasured TB costs lead to underestimates of the benefit of prevention and create conditions that could result in a resurgence of TB. We gathered data from Tarrant County, Texas, for 2002, to estimate the societal cost due to TB. METHODS: We estimated societal costs due to the presence or suspicion of TB using known variable and fixed costs incurred to all parties. These include costs for infrastructure; diagnostics and surveillance; inpatient and outpatient treatment of active, suspected, and latent TB infection (LTBI); epidemiologic activities; personal costs borne by patients and by others for lost time, disability, and death; and the cost of secondary transmission. A discount rate of 3% was used. RESULTS: During 2002, 108 TB cases were confirmed in Tarrant County, costing an estimated $40,574,953. The average societal cost per TB illness was $ 376,255. Secondary transmission created 47% and pulmonary impairment after TB created 35.4% of the total societal cost per illness. CONCLUSIONS: Prior estimates have concluded that treatment costs constitute most (86%) TB-related expenditures. From a societal perspective treatment and other direct costs account for little (3.3%) of the full burden. These data predict that preventing infection through earlier TB diagnosis and treatment of LTBI and expanding treatment of LTBI may be the most feasible strategies to reduce the cost of TB. |
