A policy of decentralised care for drug-resistant TB (DR-TB) was introduced in South Africa in 2011. We describe a trade-off between increasing coverage of services and poor quality of care, in the early phase of policy implementation. This was a mixed methods case study, comparing implementation in KwaZulu-Natal and Western Cape provinces; with interviews and quantitative analysis of routine DR-TB programme data. We analysed qualitative data, thematically organizing findings into inputs, processes, and outputs to explore how decentralisation influenced quality of DR-TB care. Decentralisation of DR-TB care expanded access across provinces but there was wide variation in pace, planning and structural readiness. Where rapid scale-up outpaced capacity-building, weaknesses in resourcing, workforce, and clinical governance compromised quality of care. Two illustrative examples highlight that decentralisation to inadequately resourced sites resulted in morbidity to patients who did not receive effective monitoring for adverse events; and decentralising services to inadequately capacitated clinicians resulted in incorrect initiation in more complex cases and late referral of clinical complications. Attempts to decentralise DR-TB treatment in the context of complex treatment algorithms and limited health system capacity resulted in trade-offs of care quality. We argue that quality of care should be an essential consideration in early implementation of health programmes.

Objectives: Treatment for multidrug-resistant/rifampicin-resistant tuberculosis (MDR/RR-TB) is increasingly transitioning from hospital-centred to community-based care. A national policy for decentralised programmatic MDR/RR-TB care was adopted in South Africa in 2011. We explored variations in the implementation of care models in response to this change in policy, and the implications of these variations for people affected by MDR/RR-TB. Design: A mixed methods study was done of patient movements between healthcare facilities, reconstructed from laboratory records. Facility visits and staff interviews were used to determine reasons for movements. Participants and setting: People identified with MDR/RR-TB from 13 high-burden districts within South Africa. Outcome measures: Geospatial movement patterns were used to identify organisational models. Reasons for patient movement and implications of different organisational models for people affected by MDR/RR-TB and the health system were determined. Results: Among 191 participants, six dominant geospatial movement patterns were identified, which varied in average hospital stay (0–281 days), average patient distance travelled (12–198 km) and number of health facilities involved in care (1–5 facilities). More centralised models were associated with longer delays to treatment initiation and lengthy hospitalisation. Decentralised models facilitated family-centred care and were associated with reduced time to treatment and hospitalisation duration. Responsiveness to the needs of people affected by MDR/RR-TB and health system constraints was achieved through implementation of flexible models, or the implementation of multiple models in a district. Conclusions: Understanding how models for organising care have evolved may assist policy implementers to tailor implementation to promote particular patterns of care organisation or encourage flexibility, based on patient needs and local health system resources. Our approach can contribute towards the development of a health systems typology for understanding how policy-driven models of service delivery are implemented in the context of variable resources.
The role of emergent champions in policy implementation for decentralised drug-resistant tuberculosis care in South Africa

Objective: Champions are recognised as important to driving organisational change in healthcare quality improvement initiatives in high-income settings. In low-income and middle-income countries with a high disease burden and constrained human resources, their role is highly relevant yet understudied. Within a broader study on policy implementation for decentralised drug-resistant tuberculosis care in South Africa, we characterised the role, strategies and organisational context of emergent policy champions. Design: Interviews with 34 healthcare workers in three South African provinces identified the presence of individuals who had a strong influence on driving policy implementation forward. Additional interviews were conducted with 13 participants who were either identified as champions in phase II or were healthcare workers in facilities in which the champions operated. Thematic analyses using a socio-ecological framework further explored their strategies and the factors enabling or obstructing their agency. Results: All champions occupied senior managerial posts and were accorded legitimacy and authority by their communities. ‘Disease-centred’ champions had a high level of clinical expertise and placed emphasis on clinical governance and clinical outcomes, while ‘patient-centred’ champions promoted pathways of care that would optimise patients’ recovery while minimising disruption in other spheres of their lives. Both types of champions displayed high levels of resourcefulness and flexibility to adapt strategies to the resource-constrained organisational context. Conclusion: Policymakers can learn from champions’ experiences regarding barriers and enablers to implementation to adapt policy. Research is needed to understand what factors can promote the sustainability of champion-led policy implementation, and to explore best management practices to support their initiatives.
"We had to manage what we had on hand, in whatever way we could": Adaptive responses in policy for decentralised drug-resistant tuberculosis care in South Africa
(Oxford University Press, 2021-02-13) Kielmann, Karina; Dickson-Hall, Lindy; Jassat, Waasila; Le Roux, Sacha; Moshabela, Mosa; Cox, Helen; Grant, Alison D.; Loveday, Marian; Hill, Jeremy; Nicol, Mark P.; Mlisana, Koleka; Black, John
In 2011, the South African National TB Programme launched a policy of decentralized management of drug-resistant tuberculosis (DR-TB) in order to expand the capacity of facilities to treat patients with DR-TB, minimize delays to access care and improve patient outcomes. This policy directive was implemented to varying degrees within a rapidly evolving diagnostic and treatment landscape for DR-TB, placing new demands on already-stressed health systems. The variable readiness of district-level systems to implement the policy prompted questions not only about differences in health systems resources but also front-line actors’ capacity to implement change in resource-constrained facilities. Using a grounded theory approach, we analysed data from indepth interviews and small group discussions conducted between 2016 and 2018 with managers (n = 9), co-ordinators (n = 15), doctors (n = 7) and nurses (n = 18) providing DR-TB care. Data were collected over two phases in district-level decentralized sites of three South African provinces. While health systems readiness assessments conventionally map the availability of ‘hardware’, i.e. resources and skills to deliver an intervention, a notable absence of systems ‘hardware’ meant that systems ‘software’, i.e. health care workers (HCWs) agency, behaviours and interactions provided the basis of locally relevant strategies for decentralized DR-TB care. ‘Software readiness’ was manifest in four areas of DR-TB care: re-organization of service delivery, redressal of resource shortages, creation of treatment adherence support systems and extension of care parameters for vulnerable patients. These strategies demonstrate adaptive capacity and everyday resilience among HCW to withstand the demands of policy change and innovation in stressed systems. Our work suggests that a useful extension of health systems ‘readiness’ assessments would include definition and evaluation of HCW ‘software’ and adaptive capacities in the face of systems hardware gaps.
