ObjectiveTo assess the outcomes of linkage to TB and HIV care and identify risk factors for poor referral outcomes.DesignCohort study of TB patients diagnosed at an urban hospital.MethodsLinkage to care was determined by review of clinic files, national death register, and telephone contact, and classified as linked to care, delayed linkage to care (>7 days for TB treatment, >30 days for HIV care), or failed linkage to care. We performed log-binomial regression to identify patient and referral characteristics associated with poor referral outcomes.ResultsAmong 593 TB patients, 23% failed linkage to TB treatment and 30.3% of the 77.0% who linked to care arrived late. Among 486 (86.9%) HIV-infected TB patients, 38.3% failed linkage to HIV care, and 32% of the 61.7% who linked to care presented late. One in six HIV-infected patients failed linkage to both TB and HIV care. Only 20.2% of HIV-infected patients were referred to a single clinic for integrated care. A referral letter was present in 90.3%, but only 23.7% included HIV status and 18.8% CD4 cell count. Lack of education (RR 1.85) and low CD4 count (CD4≤50 vs. >250cells/mm3; RR 1.66) were associated with failed linkage to TB care. Risk factors for failed linkage to HIV care were antiretroviral-naïve status (RR 1.29), and absence of referral letter with HIV or CD4 cell count (RR1.23).ConclusionsLinkage to TB/HIV care should be strengthened by communication of HIV and CD4 results, ART initiation during hospitalization and TB/HIV integration at primary care.

BACKGROUND: Xpert® MTB/RIF was expected to revolutionise the management of rifampicin‐resistant TB (RR‐TB) by enabling rapid and decentralised diagnosis of rifampicin (RIF) resistance.METHODS: We performed a care cascade analysis for a cohort of RR‐TB patients managed under programmatic conditions. Cumulative incidences of time to completion of the RR‐TB care cascade steps were estimated, reasons for delay or attrition from the cascade investigated and WHO programme indicators for monitoring of RR‐TB programmes calculated.RESULTS: Of 502 patients diagnosed with RR‐TB using Xpert, 64% initiated multidrug‐resistant TB (MDR‐TB) treatment immediately, 20% after some first‐line treatment, 16% never initiated MDR‐TB treatment, mainly because of death (44%) or loss to follow‐up (26%) soon after diagnosis. A supplementary sputum sample was collected within 14 days of treatment in 58.8% of cases. Only 63% of RR‐TB cases were assessed for isoniazid resistance, and only 65% of MDR‐TB cases were evaluated for pre‐XDR‐TB (extensively drug‐resistant TB). Treatment was individualised in 57% of pre‐XDR and 68% of XDR‐TB patients. Only 8% completed the entire RR‐TB care cascade as intended.CONCLUSION: Fidelity to the RR‐TB algorithm was poor, with substantial losses at each step of the cascade, highlighting the fact that implementation of novel technologies needs to be accompanied by health system strengthening to maximise impact.

Background In 2004 the World Health Organization WHO) released the Interim Policy on Collaborative TB/ HIV activities. According to the policy, for people living with HIV (PLWH), activities include intensified case finding, isoniazid preventive therapy (IPT) and infection control. For TB patients, activities included HIV counselling and testing HCT), prevention messages, and cotrimoxazole preventive therapy (CPT), care and support, and antiretroviral therapy ART) for those with HIV-associated TB. While important progress has been made in implementation, targets of the WHO Global Plan to Stop TB have not been reached. Objective To quantify TB/HIV integration at 3 primary healthcare clinics in Johannesburg, South Africa. Methods Routinely collected TB and HIV data from the HCT register, TB ‘suspect’ register, TB treatment register, clinic files and HIV electronic database, collected over a 3-month period, were reviewed. Results Of 1 104 people receiving HCT: 306 (28%) were HIV-positive; a CD4 count was documented for 57%; and few received TB screening or IPT. In clinic encounters among PLWH, 921 (15%) had documented TB symptoms; only 10% were assessed by smear microscopy, and few asymptomatic PLWH were offered IPT. Infection control was poorly documented and implemented. HIV status was documented for 155 (75%) of the 208 TB patients; 90% were HIV-positive and 88% had a documented CD4 count. Provision of CPT and ART was poorly documented. Conclusion The coverage of most TB/HIV collaborative activities was below Global Plan targets. The lack of standardised recording tools and incomplete documentation impeded assessment at facility level and limited the accuracy of compiled data.
