Examining the cost of community-based tuberculosis treatment in South Africa

SETTING: While South Africa has improved access to tuberculosis (TB) treatment and care, the 2015 treatment success rate for multidrug-resistant TB (MDR-TB) remains low, at 55%. Community-based TB treatment and care improves patient retention compared to the standard of care alone.OBJECTIVE: To assess the cost of a USAID-funded community-based TB model in Nelson Mandela Bay Health District (NMBHD), Eastern Cape Province, South Africa compared to the national standard of care alone.DESIGN: We estimated the cost of community-based DR-TB treatment and adherence support compared to the standard of care alone.RESULTS: Average overall costs were US$2827 lower per patient on the community-based model than the standard of care alone.CONCLUSION: The per-patient cost of the community-based model is lower than the standard of care alone. Assuming the costs and effects of a community-based model implemented in NMBHD were observed at a larger scale, implementing the model could reduce overall health system costs.

Successes, challenges and lessons from a novel deployment of Xpert(®) MTB/RIF at a major South African public event [Short Communication]

In a mobile deployment of Xpert(®) MTB/RIF (Xpert) at the public event for 2012 South African World TB Day, Xpert testing was offered to tuberculosis (TB) symptomatic clients from gold mining and surrounding communities. Considerations before implementation included effective TB symptom screening; safe, effective sputum collection; uninterrupted electricity supply; stringent instrument verification and provision of on-site results. Public event Xpert testing is feasible; however, the case-finding rate was very low (0.7%). We recommend exploring enhanced symptom screening algorithms to improve pre-test probability, cost-effectiveness analysis, exploring alternate electrical fail-safes and on-site data connectivity and improving management of client expectations.

Development of a health programme in a peri-urban informal settlement in Besters, KwaZulu-Natal

OBJECTIVES

The demographic, socio-economic and environmental status of the peri-urban informal settlement of Besters and its inhabitants' health, welfare and disability profiles were investigated for the development of a community-based health intervention programme.

STUDY DESIGN

A cross-sectional study using a structured household questionnaire assessed community health status in July 1991 in order to identify specific health and development needs through focus group discussions and community consultations. A health and development programme was established during 1992. Community participation in this programme was then assessed by measurement of the components of the health and development programme, categorised as inputs (resources), processes (activities), outputs (effects) and outcomes.

SETTING

Besters, an informal peri-urban settlement north of Durban, KwaZulu-Natal.

SUBJECTS

Residents of Besters.

RESULTS

The demographic, environmental and morbidity profiles of Besters were consistent with both South African and international studies of informal communities. Patterns of health service utilisation reflected inappropriate use of the tertiary hospital in the city centre, grossly fragmented patterns of utilisation--both for preventive and curative care and for antenatal and maternity services--and, finally, a discordance between community health needs and ability to pay for services. The interaction between input, process and output measures of community participation are discussed.

CONCLUSION

Integration of health service provision with other infrastructural development, based on community perceptions, enhances health development and community participation. Important lessons emerged about the strengths and limitations of community participation and its relevance for other communities.

Vitamin A deficiency among children in a periurban South African settlement

Preschool children (aged 3-6 y) who were living in an informal settlement within metropolitan Durban, South Africa, were assessed for vitamin A status. The serum retinol concentration of 169 children tested was 0.73 +/- 0.26 mumol/L (mean +/- SD). Nine children (5%) had vitamin A deficiency (< 0.35 mumol/L) and 75 children (44%) had low vitamin A concentrations (< 0.70 mumol/L). Conjunctival impression cytology (CIC) in 185 children revealed that 18% had poor vitamin A status as defined by two abnormal conjunctival specimens. The CIC test was a feasible and reproducible method; however, it correlated poorly with the traditionally accepted serum retinol threshold of deficiency in this population where overt vitamin A deficiency is not prevalent. This survey demonstrated that regardless of the measurement tool, there is a prevalence of subclinical vitamin A deficiency in this typical periurban informal settlement and accordingly we suggest that these children should be targeted for vitamin A-intervention strategies.
