Community TB Care Making DOTS More Accessible Dr C Davis, SOTA 2002, June 10-14, 2002
Why Community TB Care Initiative Was Needed • Sub-Saharan Africa has some of the highest TB case rates in the world, • Countries with high prevalence for HIV, have experienced huge increases in notified TB cases, • Traditional TB treatment policies - focused on hospital Rx during intensive phase - Health workers deliver TB treatment Dr C Davis, SOTA 2002, June 10-14, 2002
Why Community TB Care Needed - Congestion in hospital wards and medical departments - Overstretched resources (I.e. human, material, financial) - Patient dissatisfaction with long separation from family Dr C Davis, SOTA 2002, June 10-14, 2002

PILOTING THE COMMUNITY TB CARE INITIATIVE • WHO in collaboration with partners (CDC, USAID, IUATLD, KNCV, UNAIDS) implemented some operations research • Objective was to evaluate the effectiveness, acceptability, affordability, and cost-effectiveness of community-based TB care • Eight district based projects developed in six countries (Botswana, Kenya, Malawi, South Africa, Uganda and Zambia). Study from 1998-2000 Dr C Davis, SOTA 2002, June 10-14, 2002
EVIDENCE FROM THE PILOT SITES GUGULETU, SOUTH AFRICA • Designed to evaluate program performance and cost-effectiveness of various supervision options (clinic, community and other) for TB treatment. Major findings: -TB treatment outcomes were better for community supervised TB treatment, - Community supervision of treatment is more cost effective than wholly clinic based supervision Dr C Davis, SOTA 2002, June 10-14, 2002

Guguletu, South Africa Dr C Davis, SOTA 2002, June 10-14, 2002
EVIDENCE FROM THE PILOT SITES KIBOGA DISTRICT, UGANDA: • Study designed to compare the cost-effectiveness of community TB care to conventional hospital based care • Major findings: - Patients in the intervention group twice as likely to be treated successfully than those in the control group. - There were substantial reductions in cost and over 50% improvement in cost-effectiveness in the intervention group. - The approach was acceptable to patients, health care workers and the community. Major conclusion: Because of the success of this project, CB-DOTS has been adopted as a national policy since January 2000 Dr C Davis, SOTA 2002, June 10-14, 2002

Lessons Learned From Pilot Sites • Community-based DOTS is feasible, acceptable, and cost-effective • Successful CTBC requires close collaboration with NTP and the community • Should only be implemented where there is a functioning NTP with the 5 elements of DOTS strategy in place • Managerial expertise is essential; ensuring the decentralization of logistics for TB control (e.g. drug supply, reporting outcomes etc) Dr C Davis, SOTA 2002, June 10-14, 2002
Lessons Learned From Pilot Sites • Sustainability of the program must be planned from the start. A good situation analysis is required to identify appropriate community care providers. • Training and capacity building for the community structures are prerequisites for a successful CB-DOTS. • While CB-DOTS is more cost-effective, new resources are required for training of care providers, setting up systems, patient follow-up and supervision. • CTBC should complement and extend NTP capacity, not replace it. • Effective CB-DOTS requires a strong reporting system, access to lab facilities, and a secure drug supply. Dr C Davis, SOTA 2002, June 10-14, 2002
Approaches To Promote Community TB Care Initiative in Africa • Community TB Care is one of the strategies for DOTS expansion in the WHO/AFRO Regional TB Control Strategic Plan (2001-2005) • Guidelines for implementation of CB-DOTS are in final draft • Scaling up of pilot projects within the countries concerned ( Kenya, Malawi, Uganda) • Promotion/Dissemination of lessons learned in CTBC Initiative through sub-regional Workshops (Nairobi May 6-10, 2002) Dr C Davis, SOTA 2002, June 10-14, 2002
Thank You Dr C Davis, SOTA 2002, June 10-14, 2002
