Antiretroviral treatment among co-infected tuberculosis patients in integrated and non-integrated facilities

Background: South Africa has the second worst tuberculosis-human immunodeficiency virus (TB-HIV) syndemic in the world: in 2011, the TB-HIV co-infection rate was estimated at 65%. Integration of TB and HIV health-care services was implemented to increase antiretroviral treatment (ART) uptake among eligible patients.Aim: To evaluate whether integrated TB and HIV facilities had better ART uptake among eligible patients compared to non-integrated facilities.Methods: A cross-sectional study using routine TB programme data from January to December 2010. ART eligibility was defined as a CD4+ cell count <350 cells/μl.Results: Respectively 2761 (86.8%) and 3611 (84.7%) patients were eligible for ART at integrated and non-integrated facilities (P < 0.001). The proportion of patients started on ART at integrated facilities did not differ significantly from that of non-integrated facilities (35.9% vs. 37.1%, P = 0.340), but the proportion with unknown HIV status (31.8% vs. 24.5%, P < 0.001) and unknown CD4+ cell count (40.9% vs. 30.4%, P < 0.001) did.Conclusion: Integration of TB and HIV services in the Free State (2009–2010) was not associated with improved ART uptake. The reasons why are not clear. Of concern are the high proportions of unknown HIV status and CD4+ cell count results, especially at integrated facilities, and the small proportion of patients on ART, which may indicate poor implementation of integration.     

Integrating tuberculosis and HIV services in rural Kenya: uptake and outcomes

Setting: Seventeen rural public health facilities in Western Kenya that introduced three models of integrated care for tuberculosis (TB) and human immunodeficiency virus (HIV) patients.Objective: To assess the uptake and timing of cotrimoxazole preventive therapy (CPT) and antiretroviral treatment (ART) as well as anti-tuberculosis treatment outcomes among HIV-infected TB patients before (March–October 2010) and after (March–October 2012) the introduction of integrated TB-HIV care.Design: A before-and-after cohort study using programme data.Results: Of 501 HIV-infected TB patients, 357 (71%) were initiated on CPT and 178 (39%) on ART in the period before the introduction of integrated TB-HIV care. Following the integration of services, respectively 316 (98%) and 196 (61%) of 323 HIV-infected individuals were initiated on CPT and on ART (P < 0.001). The median time to CPT and ART initiation dropped from 7 to 2 days and from 42 to 34 days during the pre- and post-integration phases, respectively. Overall TB success rates did not vary with integration or with type of model instituted.Conclusion: Integration of TB and HIV services enhanced uptake and reduced delay in instituting CPT and ART in rural health facilities. There is a need to increase impetus in these efforts.     

Integration of TB-HIV services at an ANC facility in Frances Baard District,Northern Cape,South Africa

Background: Integrated tuberculosis-human immunodeficiency virus (TB-HIV) service delivery as part of maternal health services, including antenatal care (ANC), is widely recommended. This study assessed the implementation of collaborative TB-HIV service delivery at a hospital-based ANC service unit.Methods: A record review of a random sample of 308 pregnant women attending the ANC service between April 2011 and February 2012 was conducted. Data were extracted from registers and patient case notes. Outcomes included the proportion of women who underwent HIV counselling and testing (HCT), CD4 count testing, antiretroviral treatment (ART), cotrimoxazole preventive treatment (CPT), TB screening and isoniazid preventive treatment (IPT). Analysis measured variations in patient characteristics associated with service delivery.Results: All women underwent HCT; 80% of those who tested HIV-positive were screened for TB. Most (85.9%) of the HIV-positive women received a CD4 count. However, only 12.9% of eligible women received ART prophylaxis onsite, only 35.7% were referred for initiation of ART, only 42.3% commenced IPT and none received CPT or further investigations for TB. HIV-negative women had 2.6 higher odds (95%CI 1.3–5.3) of receiving TB screening than their HIV-positive counterparts.Conclusions: Although the identification of HIV-positive women and TB suspects was adequate, implementation of other TB-HIV collaborative activities was sub-optimal.     

Treatment outcomes of new adult tuberculosis patients in relation to HIV status in Zimbabwe

Setting:

All public health facilities in Chitungwiza District, Zimbabwe.

Objective:

To determine, in new tuberculosis (TB) patients registered in 2009, 1) the proportion of persons human immunodeficiency virus (HIV) tested, stratified by age, sex and type of TB, and 2) treatment outcomes in relation to type of TB and HIV status.

Design:

Retrospective cohort study.

Results:

Of 1800 TB patients, 1100 (61%) were tested, of whom 877 (80%) were HIV-positive and 75 (9%) were documented as receiving antiretroviral treatment (ART). HIV testing and HIV positivity were similar between patients with different types of TB. Overall, the treatment success rate was 70%, and 17% had transferred out. Being HIV-positive on ART was associated with better treatment success and lower transfer out; age ≥55 years was associated with poor treatment success and higher death rates. Defaulting was more common in those who did not undergo smear testing or in extra-pulmonary TB patients, while deaths were higher in males.

Conclusion:

In a Zimbabwe district, less than two thirds of TB patients were tested. Better treatment success was observed in patients documented as HIV-positive and on ART. Important lessons for improved TB control include increasing HIV testing uptake for better access to ART, more comprehensive recording practices on ART and better reporting on true outcomes of transfer-out patients.     

Tuberculosis among Children and Adolescents at HIV Treatment Centers in Sub-Saharan Africa

HIV-infected children and adolescents are at increased risk for tuberculosis (TB). Antiretroviral therapy (ART) reduces TB risk in HIV-infected adults, but its effectiveness in HIV-infected children and adolescents is unknown. We analyzed data from 7 integrated pediatric HIV/TB centers in 6 countries in sub-Saharan Africa. We used a Bayesian mixed-effect model to assess association between ART and TB prevalence and used adaptive lasso regression to analyze risk factors for adverse TB outcomes. The study period encompassed 57,525 patient-years and 1,160 TB cases (2,017 cases/100,000 patient-years). Every 10% increase in ART uptake resulted in a 2.33% reduction in TB prevalence. Favorable TB outcomes were associated with increased time in care and early ART initiation, whereas severe immunosuppression was associated with death. These findings support integrated HIV/TB services for HIV-infected children and adults and demonstrate the association of ART uptake with decreased TB incidence in high HIV/TB settings.     

Timing and uptake of ART during treatment for active tuberculosis in HIV co-infected adults in Malawi

Setting:

Uptake of antiretroviral therapy (ART) in patients co-infected with tuberculosis (TB) and the human immunodeficiency virus (HIV) has historically been low in Malawi. In response, the National TB Programme piloted the initiation of ART 2 weeks after initiation of TB treatment in 2008–2009, a change from the prior policy of 2 months.

Objective:

To determine at programme level if earlier initiation of ART in co-infected patients receiving TB treatment will increase the uptake and continuation of ART.

Design:

A prospective observational pilot programme evaluation using routinely collected monitoring data from the first two sites with integrated TB-HIV services in Malawi.

Results:

There was wide variability in the ART start time before and after the policy change. Before the policy change, 16% of patients initiated ART by 3 months compared to 24% after the policy change (P < 0.001). The proportion of all co-infected patients on ART increased from 32% before the policy change to 39% after (P < 0.001). Earlier initiation of ART did not increase the occurrence of side effects and did not reduce adherence to TB treatment.

Conclusion:

Earlier initiation of ART in co-infected patients receiving TB treatment improved the uptake and continuation of ART. Malawi ART guidelines in 2011 were changed from initiating ART after 2 months to as soon as possible after starting anti-tuberculosis treatment.     

Population Size Estimation of Men Who Have Sex with Men in Ho Chi Minh City and Nghe An Using Social App Multiplier Method

This study aims to estimate the number of men who have sex with men (MSM) in Ho Chi Minh City (HCMC) and Nghe An province, Viet Nam, using a novel method of population size estimation, and to assess the feasibility of the method in implementation. An innovative approach to population size estimation grounded on the principles of the multiplier method, and using social app technology and internet-based surveys was undertaken among MSM in two regions of Viet Nam in 2015. Enumeration of active users of popular social apps for MSM in Viet Nam was conducted over 4 weeks. Subsequently, an independent online survey was done using respondent driven sampling. We also conducted interviews with key informants in Nghe An and HCMC on their experience and perceptions of this method and other methods of size estimation. The population of MSM in Nghe An province was estimated to be 1765 [90% CI 1251–3150]. The population of MSM in HCMC was estimated to be 37,238 [90% CI 24,146–81,422]. These estimates correspond to 0.17% of the adult male population in Nghe An province [90% CI 0.12–0.30], and 1.35% of the adult male population in HCMC [90% CI 0.87–2.95]. Our size estimates of the MSM population (1.35% [90% CI 0.87%–2.95%] of the adult male population in HCMC) fall within current standard practice of estimating 1–3% of adult male population in big cities. Our size estimates of the MSM population (0.17% [90% CI 0.12–0.30] of the adult male population in Nghe An province) are lower than the current standard practice of estimating 0.5–1.5% of adult male population in rural provinces. These estimates can provide valuable information for sub-national level HIV prevention program planning and evaluation. Furthermore, we believe that our results help to improve application of this population size estimation method in other regions of Viet Nam.     

Management and treatment outcomes of patients enrolled in MDR-TB treatment in Viet Nam

Setting: The programmatic management of drug-resistant tuberculosis (TB) in Viet Nam has been rapidly scaled up since 2009.Objectives: To document the annual numbers of patients enrolled for multidrug-resistant tuberculosis (MDR-TB) treatment during 2010–2014 and to determine characteristics and treatment outcomes of patients initiating treatment during 2010–2012.Design: A retrospective cohort study using national reports and data from the national electronic data system for drug-resistant TB.Results: The number of patients enrolled annually for MDR-TB treatment increased from 97 in 2010 to 1522 in 2014. The majority of patients were middle-aged men who had pulmonary disease and had failed a retreatment regimen; 77% had received ⩾2 courses of TB treatment. Favourable outcomes (cured and treatment completed) were attained in 73% of patients. Unfavourable outcomes included loss to follow-up (12.5%), death (8%) and failure (6.3%). Having had ⩾2 previous treatment courses and being human immunodeficiency virus-positive were associated with unfavourable outcomes.Conclusion: Increasing numbers of patients are being treated for MDR-TB each year with good treatment outcomes under national programme management in Viet Nam. However, there is a need to increase case detection—currently at 30% of the estimated 5100 MDR-TB cases per year, reduce adverse outcomes and improve monitoring and evaluation.     

Antiretroviral therapy uptake among adult tuberculosis patients newly diagnosed with HIV in Nyanza Province,Kenya

Setting:

In 2008, the Kenya tuberculosis (TB) program reported low (31%) antiretroviral therapy (ART) uptake among human immunodeficiency virus (HIV) infected TB patients.

Objective:

To confirm ART coverage and identify factors associated with HIV clinic enrollment and ART initiation among TB patients.

Design:

Retrospective chart abstraction of adult TB patients newly diagnosed with HIV and eligible for ART at 58 Nyanza Province TB clinics between October 2006 and April 2008. TB data were linked to HIV clinic data at 50 facilities that provided ART. Associations with HIV clinic enrollment and ART were evaluated.

Results:

Among 1137 ART-eligible TB patient records sampled, 32% documented HIV clinic enrollment and 29% ART. Date fields were largely incomplete; 11% of the patient records included HIV testing dates and ≤1% had dates for cotrimoxazole prophylaxis, HIV clinic enrollment and ART initiation. Adding HIV clinic data increased HIV clinic enrollment and ART documentation to respectively 62% and 44%. Among TB patients in HIV care, female sex, older age group and baseline CD4 documentation were associated with ART initiation.

Conclusion:

Linking data increased documentation of HIV clinic enrollment and ART uptake. Continued efforts are required to improve the documentation of HIV service delivery, especially in TB clinics. Interventions to increase ART uptake are needed for younger patients and men.     

HIV-TB co-infection in children: associated factors and access to HIV services in Lagos,Nigeria

Background: Human immunodeficiency virus (HIV) and tuberculosis (TB) are the leading causes of death from infectious disease worldwide. The World Health Organization estimates that the prevalence of HIV among children with TB in moderate to high prevalence countries ranges between 10% and 60%. This study aimed to determine the access to HIV services of HIV-TB co-infected children.Methods: A retrospective review of data of children diagnosed with TB in Lagos State, Nigeria from 1 January 2012 to 31 December 2013.Results: A total of 1199 children aged between 0 and 14 years were diagnosed with TB. Of 1095 (91.3%) who underwent testing for HIV, 320 (29.2%) were HIV seropositive. The male-to-female ratio of HIV-TB positive outcomes was 1:0.9. Of the 320 HIV-TB co-infected children, 57 (17.8%) were aged <1 year, 86 (26.9%) 1–4 years and 186 (58.1%) 5–14 years; 186/320 (58.1%) began cotrimoxazole preventive therapy (CPT), and 151 (47.2%) were put on antiretroviral treatment (ART). ART uptake was not significantly higher in facilities where HIV-TB services were co-located (P > 0.05).Conclusion: The uptake of CPT and ART was low. There is a need to intensify efforts to improve access to HIV services in Lagos State, Nigeria.     

Are HIV-positive presumptive tuberculosis patients without tuberculosis getting the care they need in Zimbabwe?

Setting: Emakhandeni Clinic provides decentralised and integrated tuberculosis (TB) and human immunodeficiency virus (HIV) care in Bulawayo, Zimbabwe.Objectives: To compare HIV care for presumptive TB patients with and without TB registered in 2013.Design: Retrospective cohort study using routine programme data.Results: Of 422 registered presumptive TB patients, 26% were already known to be HIV-positive. Among the remaining 315 patients, 255 (81%) were tested for HIV, of whom 190 (75%) tested HIV-positive. Of these, 26% were diagnosed with TB and 71% without TB (3% had no TB result recorded). For the 134 patients without TB, antiretroviral treatment (ART) eligibility data were recorded for 42 (31%); 95% of these were ART eligible. Initiation of cotrimoxazole preventive therapy (CPT) and ART was recorded for respectively 88% and 90% of HIV-positive patients with TB compared with respectively 40% and 38% of HIV-positive patients without TB (P < 0.001).Conclusion: Presumptive TB patients without TB had a high HIV positivity rate and, for those with available data, most were ART eligible. Unlike HIV-positive patients diagnosed with TB, CPT and ART uptake for these patients was poor. A ‘test and treat’ approach and better service linkages could be life-saving for these patients, especially in southern Africa, where there are high burdens of HIV and TB.     

2014－2017年南宁市农村地区TB/HIV双重感染患者登记变化趋势分析

目的 分析2014－2017年南宁市农村地区结核分枝杆菌(TB)/艾滋病病毒(HIV)双重感染(简称TB-HIV感染)患者的登记变化趋势,为制定TB-HIV双重感染防控措施提供科学依据。 方法 整理2014－2017年南宁市所有县的TB-HIV双重感染防治工作年度报表数据,统计分析不同年度、不同地区TB-HIV双重感染患者登记、结核病患者筛查HIV和HIV/艾滋病(AIDS)患者筛查TB的报告登记变化情况, 并对登记报告的趋势进行归因和责任分析。 结果 2014－2017年,南宁市农村地区TB-HIV感染患者占结核病患者的比例为5.28％,其中,横县TB-HIV感染患者占结核病患者的比例逐年上升(χ²=24.260, P＜0.001),宾阳县TB-HIV感染患者占结核病患者的比例则逐年下降(χ²=5.518, P＜0.05),各县之间2014－2017年总TB-HIV感染患者占结核病患者的比例差异有统计学意义(χ²=141.132, P＜0.001)。2014-2016年,全市TB-HIV感染患者报告数上升了108.97％,其中,HIV/AIDS患者筛查TB登记报告上升150.79％,结核病患者筛查HIV登记报告下降66.67％;马山县HIV/AIDS患者筛查TB登记报告上升了543.75％,横县HIV/AIDS患者筛查TB登记报告上升了933.33％,宾阳县TB筛查HIV报告上升了300％,而HIV/AIDS患者筛查TB登记报告则下降了66.67％。因马山县和横县的HIV/AIDS患者筛查TB登记造成上升的责任比例分别为102.35%和24.71%,因宾阳县的HIV/AIDS患者筛查TB登记造成下降的责任比例为-11.77%。 结论 2014-2016年南宁市农村地区TB-HIV感染患者登记快速上升,主要由马山县和横县的HIV/AIDS患者筛查TB登记上升引起。应进一步加强和完善结核病和艾滋病综合服务机制,对专业人员进行技能培训,并采用多种筛查和检测方法,更高质量的发现、治疗现有以及潜在的TB-HIV双重感染者,有效控制结核病和艾滋病疫情的蔓延。     

Time to unsuccessful tuberculosis treatment outcome,Cambodia, China,and Viet Nam

Objective:

To determine the frequency and characteristics of patients with unsuccessful tuberculosis (TB) treatment.

Methods:

Random selection of TB case registers among all treatment units in Cambodia, two provinces in China, and Viet Nam. The data of two calendar years were analyzed to assess unsuccessful outcomes and their time of occurrence.

Results:

Among the 33 309 TB patients, treatment was unsuccessful in respectively 10.1%, 3.0% and 9.1% of patients in Cambodia, China and Viet Nam. The risk of death was highest in Cambodia, higher among males than females, increased with age, and was more common among retreatment cases than new cases, and among patients with a high than a low sputum smear microscopy grade. Half of all deaths occurred in the first 2 months in Cambodia and within 11 weeks in China and Viet Nam. Median time to default was 3 months in Cambodia and Viet Nam, and about 2 months in China.

Conclusions:

Treatment was highly successful in the three study countries, with a low proportion of death and default. As the majority of defaulting occurs at the beginning of treatment, all countries should critically review their current policy of treatment support in this period.     

ART uptake,its timing and relation to anti-tuberculosis treatment outcomes among HIV-infected TB patients

Setting:

All public health facilities in two provinces of Zimbabwe.

Objective:

To determine, among tuberculosis (TB) patients with human immunodeficiency virus (HIV) registered in 2010, 1) the proportion started on antiretroviral treatment (ART), 2) the timing of ART in relation to the start of anti-tuberculosis treatment, and 3) whether timing of ART influenced anti-tuberculosis treatment outcomes.

Design:

Retrospective cohort study.

Results:

Of the 2655 HIV-positive TB patients, 1115 (42%) were documented as receiving ART. Of these, 178 (16%) started ART prior to anti-tuberculosis treatment. Of those who started after anti-tuberculosis treatment, 17% started within 2 weeks, 43% between 2 and 8 weeks and 40% after 8 weeks. Treatment success in the cohort was 82%, with 14% deaths before completion of anti-tuberculosis treatment. Not receiving ART during anti-tuberculosis treatment was associated with lower anti-tuberculosis treatment success (adjusted RR 0.70, 95%CI 0.53–0.91) and more deaths (adjusted RR 3.43, 95%CI 2.2–5.36). There were no differences in TB treatment outcomes by timing of ART initiation.

Conclusion:

ART uptake is low given the improved treatment outcomes in those put on ART during anti-tuberculosis treatment. Better integration of HIV and TB services is needed to ensure increased coverage and earlier ART uptake.     

广西壮族自治区结核分枝杆菌/HIV联合感染患者抗病毒治疗对死亡影响的分析

目的 分析抗病毒治疗(ART)对结核分枝杆菌/HIV联合感染患者(TB/HIV)死亡的影响。方法 收集2011年广西壮族自治区(广西)各市、县(区)结核病监测系统中既往HIV阳性和新确诊HIV阳性的结核病(TB)患者信息,经核对“中国疾病预防控制系统-艾滋病综合防治信息系统”信息,确定TB/HIV;采用回顾性对照研究方法,按是否开展ART将患者分为ART和非ART两组,用统计学方法比较两组患者特征,并计算死亡比例,采用Kaplan-Meier法分析两组生存情况,同时分析死亡优势比和开始抗结核治疗1年内ART保护率。结果 519例TB/HIV中,100例(19.3%)开展ART;开展抗结核治疗1年内84例(16.2%)死亡,其中ART组8例(9.5%),非ART组76例(占死亡患者90.5%);ART组死亡占TB/HIV总数的8.08%,非ART组死亡占TB/HIV总数的18.7%,两组差异有统计学意义(χ²=6.12,P<0.01);Kaplan-Meier生存曲线显示,ART组TB/HIV治疗开始1年内生存概率大于非ART组;两组生存曲线差异有统计学意义(P<0.05);相对于ART组,非ART组TB/HIV死亡优势比为2.31;ART组在抗结核第一年内能保护56.7%的TB/HIV免于死亡。结论 在抗结核开始1年内,非ART组TB/HIV死亡比例显着高于ART组;ART患者生存时间较非ART组长;ART可以保护半数以上TB/HIV在抗结核开始1年内免于死亡;为挽救更多生命,需不断提高TB/HIV中ART覆盖面。     

HIV testing and treatment among tuberculosis patients --- Kenya, 2006-2009

In resource-limited settings, high case-fatality rates are seen among tuberculosis (TB) patients with human immunodeficiency virus (HIV) infection, especially during the early months of TB treatment. HIV prevalence among TB patients has been estimated to be as high as 80%--90% in some areas of sub-Saharan Africa. In 2004, the World Health Organization (WHO) recommended increasing collaboration between HIV and TB programs. Since then, many countries, including Kenya, have worked to increase TB/HIV collaborative activities. In 2005, the Kenya Division of Leprosy, Tuberculosis, and Lung Disease (DLTLD) added questions regarding HIV testing and treatment to the existing TB surveillance system.* This report summarizes HIV data collected from Kenya's extended TB surveillance system during 2006--2009. During this period, HIV testing among TB patients increased from 60% in 2006 to 88% in 2009, and the prevalence of HIV infection among TB patients tested decreased from 52% to 44%. In 2009, 92% of HIV-infected TB patients received cotrimoxazole prophylaxis for the prevention of opportunistic infections. Although these data highlight the increase in HIV services provided to TB patients, only 34% of HIV-infected TB patients started antiretroviral therapy (ART) while being treated for TB. Innovative interventions are needed to increase HIV treatment among TB patients in Kenya, especially considering the 2009 WHO guidelines recommending that all HIV-infected TB patients be started on ART as soon as possible, regardless of CD4 count. Although these guidelines have not yet been implemented in Kenya, officials are working to identify methods of increasing access to ART for TB patients.     

Implementation of GINA guidelines in Ho Chi Minh City: a model for Viet Nam

Setting:

The Global Initiative for Asthma (GINA) guidelines have not been implemented effectively in primary care settings in Viet Nam.

Objectives:

To estimate the proportion of patients with controlled asthma and the direct health care costs of managing asthma according to GINA guidelines at four out-patient clinics in Ho Chi Minh City (HCMC), Viet Nam.

Methods:

One hundred and six patients with asthma were treated and followed up according to GINA guidelines for 12 months. Clinical and pulmonary function responses and direct health care costs were evaluated every 3 months during the study.

Results:

The proportion of patients with controlled asthma rose from 1.0% at the start of the study to 36.8% by the end of the study (P < 0.0001). The proportion of patients who had at least one hospitalisation per year decreased significantly, from 32.1% to 5.7% (P < 0.0001). The annual per patient median direct health care cost was US$169. Using asthma controllers continuously gave better asthma control than using them intermittently (OR 12.9, 95%CI 4.7–35.7).

Conclusions:

The implementation of GINA guidelines at out-patient clinics in HCMC, Viet Nam, improved asthma control with modest direct health care costs.     

Antiretroviral therapy during tuberculosis treatment and marked reduction in death rate of HIV-infected patients, Thailand

Antiretroviral therapy (ART) is lifesaving in patients with advanced HIV infection, but the magnitude of benefit in HIV-infected patients receiving tuberculosis (TB) treatment remains uncertain, and population-based data from developing countries are limited. We prospectively collected data about HIV-infected TB patients from February 2003 through January 2004 in Ubon-ratchathani, Thailand. During 12 months, HIV was diagnosed in 329 (14%) of 2,342 patients registered for TB treatment. Of patients with known outcomes, death during TB treatment occurred in 5 (7%) of 71 who received ART and 94 (43%) of 219 who did not. Using multivariate analysis, we found a large reduction in the odds of death for patients receiving ART before or during TB treatment (odds ratio, 0.2; 95% confidence interval, 0.1-0.5), adjusting for CD4 count, smear status, co-trimoxazole use, and treatment facility. ART is associated with a substantial reduction in deaths during TB treatment for HIV-infected TB patients in Thailand.     

Tuberculosis and HIV co-infection in healthcare workers in England and Wales, 1999-2005

This study used linked national tuberculosis (TB) and HIV surveillance data to investigate recent trends and factors associated with HIV co-infection (TB-HIV) in healthcare workers (HCWs) with TB in England and Wales. Methods applied were the χ2 trend test and logistic regression. Overall 14% (231/1627) of HCWs with TB were co-infected with HIV, increasing from 8% in 1999 to 14% in 2005 (P<0·001). Most (78%) HCWs were non-UK born and 74% of these developed TB ?2 years post-entry. Being born in Sub-Saharan Africa was an independent predictor for TB-HIV, especially for female HCWs (odds ratio 66·5, 95% confidence interval 16·3-271·1), who also had a lower median CD4 count than other co-infected women (106/mm3, interquartile range 40-200, P<0·01). Voluntary HIV testing of new HCWs should be encouraged as an opportunity for early diagnosis. Post-entry, a high index of clinical suspicion for TB in those most at risk remains important.
