Barriers and enablers to implementing tuberculosis control strategies in EU and European Economic Area countries: a systematic review. THE LANCET. INFECTIOUS DISEASES 2021; 21:e272-e280. [PMID: 34450080 DOI: 10.1016/s1473-3099(21)00077-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Revised: 01/26/2021] [Accepted: 01/28/2021] [Indexed: 11/25/2022]
Abstract
Meeting the 2035 WHO targets of reducing tuberculosis incidence by 90% from 2015 levels requires the implementation of country-specific tuberculosis control strategies. This systematic review aims to identify factors that facilitate or impede the implementation of such strategies in EU and European Economic Area (EEA) settings. Focusing on providers of care, health system constraints, and social and political factors, this Review complements available evidence on the accessibility of tuberculosis services to recipients of care. Databases were searched for EU and EEA articles published between Jan 1, 1997, and Nov 6, 2020, that presented empirical data on tuberculosis policies, strategies, guidelines, or interventions. 2061 articles were screened and 65 were included. The most common barrier to tuberculosis control strategies described the divergence of health-care practices from guidelines, often related to inadequate knowledge or perceived usefulness of the guidelines by clinicians. The most commonly identified enabler to tuberculosis control strategies was the documented positive attitudes of health-care workers towards tuberculosis programmes. Divergence between clinical practice and guidelines was described in most EU and EEA settings, indicating the need for a focused review of guideline adherence. Strengths of this study involve its broad inclusion criteria and wide range of tuberculosis control strategies analysed.

Chemtob D, Ogum E. Tuberculosis treatment outcomes of non-citizen migrants: Israel compared to other high-income countries. Isr J Health Policy Res 2020; 9:29. [PMID: 32741367 PMCID: PMC7397670 DOI: 10.1186/s13584-020-00386-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2020] [Accepted: 05/26/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND In TB low incidence countries, the outcome of TB treatment among non-citizen migrants from endemic countries affects ability to eliminate TB. This study compares TB treatment outcomes among non-citizen migrants in select pre-elimination country based on their policies for non-citizen migrant TB patients in order to determine how policy affects TB outcomes. METHODS A literature review was conducted via PUBMED, MEDLINE (2000-2017) on TB policy among non-citizen migrants and treatment outcome. Treatment outcome among migrants diagnosed in Israel during 2000-2014 was analysed. RESULTS In total, 18 publications met the inclusion criteria. All the countries reviewed except the United States offered free TB treatment to undocumented migrants. Successful TB treatment outcome for non-citizen migrants in Israel was 87%, the Netherlands was 90.7%, the UK was 82.1%, and outcomes in the US and Australia were not published. CONCLUSIONS There is a need to standardize results based on international definitions of migrants, asylum seekers, and refugees in order to determine status-specific barriers and to facilitate international comparisons. Policies insuring free access to TB care for non-citizen migrants are an important element for TB elimination in low incidence countries.

Abstract
INTRODUCTION Well-coordinated multidisciplinary teams are essential for better tuberculosis (TB) control. Our objective was to evaluate the impact of Spanish Society of Pneumology (SEPAR) accreditation of TB Units (TBU) and to determine differences between the accredited and non-accredited centers. MATERIAL AND METHODS DESIGN Observational descriptive study based on a self-administered survey from October 2014 to February 2018 completed by 139 heads of respiratory medicine departments collected by SEPAR, before and after TBU accreditation. VARIABLES demographic, epidemiological and contact tracing (CT) variables, among others. ANALYSIS basic descriptive analysis, and calculation of medians for continuous variables and proportions for categorical variables. The variables were compared using the Chi-squared test and logistic regression. RESULTS The response rate was 54.7% and 43.2% in the pre- and post-TBU accreditation period, respectively. No differences were observed in the care and coordination variables between the pre- and post-accreditation survey, nor in the organization when only accredited centers were analyzed. When we compared the accredited and non-accredited centers, significant differences were detected in the collection of the final conclusion, management of resistance, coordination with other departments, contact tracing, and directly observed treatment. CONCLUSIONS The approach of different professionals with regard to TB has been addressed. Positive aspects and areas for improvement have been detected, and better results were observed in the accredited versus non-accredited centers. A closer supervision of TBUs is necessary to improve their effectiveness.

Higher Rate of Tuberculosis in Second Generation Migrants Compared to Native Residents in a Metropolitan Setting in Western Europe. PLoS One 2015; 10:e0119693. [PMID: 26061733 PMCID: PMC4465484 DOI: 10.1371/journal.pone.0119693] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2014] [Accepted: 05/14/2015] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND In Western Europe, migrants constitute an important risk group for tuberculosis, but little is known about successive generations of migrants. We aimed to characterize migration among tuberculosis cases in Berlin and to estimate annual rates of tuberculosis in two subsequent migrant generations. We hypothesized that second generation migrants born in Germany are at higher risk of tuberculosis compared to native (non-migrant) residents. METHODS A prospective cross-sectional study was conducted. All tuberculosis cases reported to health authorities in Berlin between 11/2010 and 10/2011 were eligible. Interviews were conducted using a structured questionnaire including demographic data, migration history of patients and their parents, and language use. Tuberculosis rates were estimated using 2011 census data. RESULTS Of 314 tuberculosis cases reported, 154 (49.0%) participated. Of these, 81 (52.6%) were first-, 14 (9.1%) were second generation migrants, and 59 (38.3%) were native residents. The tuberculosis rate per 100,000 individuals was 28.3 (95CI: 24.0-32.6) in first-, 10.2 (95%CI: 6.1-16.6) in second generation migrants, and 4.6 (95%CI: 3.7-5.6) in native residents. When combining information from the standard notification variables country of birth and citizenship, the sensitivity to detect second generation migration was 28.6%. CONCLUSIONS There is a higher rate of tuberculosis among second generation migrants compared to native residents in Berlin. This may be explained by presumably frequent contact and transmission within migrant populations. Second generation migration is insufficiently captured by the surveillance variables country of birth and citizenship. Surveillance systems in Western Europe should allow for quantifying the tuberculosis burden in this important risk group.

Abstract
This cross-sectional survey aimed to examine the epidemiology of tuberculosis (TB) in European Union (EU) and European Economic Area (EEA) cities with populations greater than 500,000. National TB programme managers were asked to provide data on big city population size, total number of notified TB cases in big cities and national notification rate for 2009. A rate ratio was calculated using the big city TB notification rate as a numerator and country TB notification rate, excluding big city TB cases and population, as a denominator. Twenty of the 30 EU/EEA countries had at least one big city. Pooled rate ratios were 2.5, 1.0, and 0.7 in low-, intermediate- and high-incidence countries respectively. In 15 big cities, all in low-incidence countries, rate ratios were twice the national notification rate. These data illustrate the TB epidemiology transition, a situation whereby TB disease concentrates in big cities as national incidence falls, most likely as a result of the higher concentration of risk groups found there. This situation requires targeted interventions and we recommend that big city TB data, including information about patients' risk factors, are collected and analysed systematically, and that successful interventions are shared.

Abstract
In low-incidence countries in the European Union (EU), tuberculosis (TB) is concentrated in big cities, especially among certain urban high-risk groups including immigrants from TB high-incidence countries, homeless people, and those with a history of drug and alcohol misuse. Elimination of TB in European big cities requires control measures focused on multiple layers of the urban population. The particular complexities of major EU metropolises, for example high population density and social structure, create specific opportunities for transmission, but also enable targeted TB control interventions, not efficient in the general population, to be effective or cost effective. Lessons can be learnt from across the EU and this consensus statement on TB control in big cities and urban risk groups was prepared by a working group representing various EU big cities, brought together on the initiative of the European Centre for Disease Prevention and Control. The consensus statement describes general and specific social, educational, operational, organisational, legal and monitoring TB control interventions in EU big cities, as well as providing recommendations for big city TB control, based upon a conceptual TB transmission and control model.

Abstract
SETTING Tuberculosis (TB) incidence is rising globally, with drug resistance becoming increasingly problematic. Microbiological confirmation ensures correct anti-tuberculous chemotherapy. OBJECTIVE/DESIGN We retrospectively analysed all TB cases diagnosed in Central Manchester in 2009 investigating how often we are not achieving microbiological diagnosis, factors influencing this and whether opportunities to obtain microbiological samples are missed. RESULTS 128/156 (82%) cases had samples sent for microbiology. Factors affecting this included disease site, with ocular disease least likely to be sampled (p < 0.0001), and patient age (with children less likely to be sampled p = 0.002). Ethnicity did not affect sampling (n.s.). Overall, 92/156 (59%) cases were culture positive. Negative culture was related to specimen type (p < 0.0001) and patient age (p = 0.019), with children significantly less likely to have a positive culture. Ethnicity and disease site did not affect culture results. There was a trend towards culture positivity being more common in pulmonary (75%) than non-pulmonary (46%) disease (n.s.). In only 7 (4%), could samples have been sent where they were originally absent (3) or further samples obtained where the cultures proved to be negative (4). CONCLUSION Despite an overall culture positive rate of 59%, opportunities to achieve microbiological confirmation are seldom missed. In our centre, which is typical of UK practice, this lack of capacity to increase microbiological confirmation, particularly in an era of increasing importance of extra-pulmonary TB, is concerning. Improvements in sample acquisition and laboratory methods are urgently required.

Abstract
According to WHO estimates, in 2010 there were 8.8 million new cases of tuberculosis (TB) and 1.5 million deaths. TB has been classically associated with poverty, overcrowding and malnutrition. Low income countries and deprived areas, within big cities in developed countries, present the highest TB incidences and TB mortality rates. These are the settings where immigration, important social inequalities, HIV infection and drug or alcohol abuse may coexist, all factors strongly associated with TB. In spite of the political, economical, research and community efforts, TB remains a major global health problem worldwide. Moreover, in this new century, new challenges such as multidrug-resistance extension, migration to big cities and the new treatments with anti-tumour necrosis alpha factor for inflammatory diseases have emerged and threaten the decreasing trend in the global number of TB cases in the last years. We must also be aware about the impact that smoking and diabetes pandemics may be having on the incidence of TB. The existence of a good TB Prevention and Control Program is essential to fight against TB. The coordination among clinicians, microbiologists, epidemiologists and others, and the link between surveillance, control and research should always be a priority for a TB Program. Each city and country should define their needs according to the epidemiological situation. Local TB control programs will have to adapt to any new challenge that arises in order to respond to the needs of their population.

Abstract
Tuberculosis (TB) is a multi-faceted illness associated with a long and fascinating history. Although much has changed in the diagnosis, treatment and prevention of TB over the past six decades, many of the challenges remain remarkably similar. In developing solutions to these challenges, key stakeholders and politicians would do well to learn from some of the more effective strategies from the pre-chemotherapy era. Despite working with insufficient resources, nurses have historically contributed significantly to the work of the multidisciplinary teams in delivering care to patients and families, as well as in implementing national TB control and prevention programmes. The current resurgence of TB in the UK makes it imperative to achieve consistently and appropriately-funded TB services across the country. Whether NHS commissioners and politicians will engage with nurses and others in the reconfigured NHS to achieve this, however, remains to be seen.

Abstract
Historically, an association between tuberculosis and diabetes was recognised clinically, and the recent global rise in diabetes prevalence has reignited interest. We therefore quantified the tuberculosis-diabetes association using US survey data. A case-control analysis was performed using cross-sectional data from the second National Health and Nutrition Examination Survey (1976-1980; civilian non-institutionalised US population aged 20-74). Cases were respondents ever diagnosed with tuberculosis, and controls were respondents who reported never receiving a tuberculosis diagnosis. Exposure to diabetes and intermediate hyperglycaemia was defined using a self-reported measure, an oral glucose tolerance test, or both. We used logistic regression to estimate an adjusted odds ratio, controlling for potential major confounders. In relation to the main exposure measure, the adjusted odds ratio for the association between tuberculosis and diabetes varied between 2.31 (95% confidence interval 1.36-3.93) and 2.36 (95% confidence interval 1.40-3.97), depending on the model. No association was found for intermediate hyperglycaemia, with adjusted odds ratio varying between 1.33 (95% confidence interval 0.49-3.64) and 1.34 (95% confidence interval 0.50-3.62), depending on model. Irrespective of the exposure measure and the confounders controlled for, diabetes was associated with an increased tuberculosis risk. This study may underestimate the true association due to exposure misclassification.

Abstract
Tuberculosis (TB) is still a serious public health issue, even in large cities in developed countries. Control of this old disease is based on complicated programs that require completion of long treatments and contact tracing. In an accompanying research article published in BMC Public Health, Bothamley and colleagues found that areas with a ratio lower than one nurse per forty notifications had increased rates with respect to TB notifications, smear-positive cases, loss to follow-up and treatment abandonment across the UK. Furthermore, in these areas there was less opportunity for directly observed therapy, assistance with complex needs, educational outreach and new-entrant screening. In this commentary, we discuss the importance of improving organizational aspects and evaluating TB control programs. According to Bothamley and colleagues, a ratio of one nurse per forty notifications is an effective method of reducing the high TB incidences observed in London and in other cities in developed countries, or to maintain the decline in incidence in cities with lower incidences. It is crucial to evaluate TB programs every year to detect gaps early.
