Cost-effectiveness of a national population-based screening program for type 2 diabetes: the Brazil experience

Background: The cost-effectiveness of screening for type 2 diabetes mellitus (DM2) in developing countries remains unknown. The Brazilian government conducted a nationwide population screening program for type 2 diabetes mellitus (BNDSP) in which 22 million capillary glucose tests were performed in individuals aged 40 years and older. The objective of this study was to evaluate the life-time cost-effectiveness of a national population-based screening program for DM2 conducted in Brazil. Methods: We used a Markov-based cost-effectiveness model to simulate the long-term costs and benefits of screening for DM2, compared to no screening program. The analysis was conducted from a public health care system perspective. Sensitivity analyses were conducted to examine the robustness of results to key model parameters. Results: Brazilian National diabetes screening program will yield a large health benefit and higher costs. Compared with no screening, screen detection of undiagnosed diabetes resulted in US$31,147 per QALY gained. Results from sensitivity analyses found that screening targeted at hypertensive individuals would cost US$ 22,695/QALY. When benefits from early glycemic control on cardiovascular outcomes were considered, the cost per QALY gained would reduce significantly. Conclusions: In the base case analysis, not considering the intangible benefit of transferring diabetes management to primary care nor the benefit of using statin to treat eligible diabetic patients, CE ratios were not cost-effective considering thresholds proposed by the World Health Organization. However, significant uncertainty was demonstrated in sensitivity analysis. Our results indicate that policy-makers should carefully balance the benefit and cost of the program while considering using a population-based approach to screen for diabetes

Developing recommendations to improve the quality of diabetes care in Ireland: a policy analysis

BACKGROUND: In 2006, the Health Service Executive (HSE) in Ireland established an Expert Advisory Group (EAG) for Diabetes, to act as its main source of operational policy and strategic advice for this chronic condition. The process was heralded as the starting point for the development of formal chronic disease management programmes. Although recommendations were published in 2008, implementation did not proceed as expected. Our aim was to examine the development of recommendations by the EAG as an instrumental case study of the policy formulation process, in the context of a health system undergoing organisational and financial upheaval. METHODS: This study uses Kingdon’s Multiple Streams Theory to examine the evolution of the EAG recommendations. Semi-structured interviews were conducted with a purposive sample of 15 stakeholders from the advisory group. Interview data were supplemented with documentary analysis of published and unpublished documents. Thematic analysis was guided by the propositions of the Kingdon model. RESULTS: In the problem stream, the prioritisation of diabetes within the policy arena was a gradual process resulting from an accumulation of evidence, international comparison, and experience. The policy stream was bolstered by group consensus rather than complete agreement on the best way to manage the condition. The EAG assumed the politics stream was also on course to converge with the other streams, as the group was established by the HSE, which had the remit for policy implementation. However, the politics stream did not converge due to waning support from health service management and changes to the organisational structure and financial capacity of the health system. These changes trumped the EAG process and the policy window remained closed, stalling implementation. CONCLUSIONS: Our results reflect the dynamic nature of the policy process and the importance of timing. The results highlight the limits of rational policy making in the face of organisational and fiscal upheaval. Diabetes care is coming on to the agenda again in Ireland under the National Clinical Care Programme. This may represent the opening of a new policy window for diabetes services, the challenge will be maintaining momentum and interest in the absence of dedicated resources.
