Health impact of external funding for HIV, tuberculosis and malaria: systematic review

Background Since 2002, development assistance for health has substantially increased, especially investments for HIV, tuberculosis (TB) and malaria control. We undertook a systematic review to assess and synthesize the existing evidence in the scientific literature on the health impacts of these investments. Methods and findings We systematically searched databases for peer-reviewed and grey literature, using tailored search strategies. We screened studies for study design and relevance, using predefined inclusion criteria, and selected those that enabled us to link health outcomes or impact to increased external funding. For all included studies, we recorded dataset and study characteristics, health outcomes and impacts. We analysed the data using a causal-chain framework to develop a narrative summary of the published evidence. Thirteen articles, representing 11 individual studies set in Africa and Asia reporting impacts on HIV, tuberculosis and malaria, met the inclusion criteria. Only two of these studies documented the entire causal-chain spanning from funding to programme scale-up, to outputs, outcomes and impacts. Nonetheless, overall we find a positive correlation between consecutive steps in the causal chain, suggesting that external funds for HIV, tuberculosis and malaria programmes contributed to improved health outcomes and impact. Conclusions Despite the large number of supported programmes worldwide and despite an abundance of published studies on HIV, TB and malaria control, we identified very few eligible studies that adequately demonstrated the full process by which external funding has been translated to health impact. Most of these studies did not move beyond demonstrating statistical association, as opposed to contribution or causation. We thus recommend that funding organizations and researchers increase the emphasis on ensuring data capture along the causal pathway to demonstrate effect and contribution of external financing. The findings of these comprehensive and rigorously conducted impact evaluations should also be made publicly accessibl

Should outbreak response immunization be recommended for measles outbreaks in middle- and low-income countries? An update.

Measles caused mortality in >164,000 children in 2008, with most deaths occurring during outbreaks. Nonetheless, the impact and desirability of conducting measles outbreak response immunization (ORI) in middle- and low-income countries has been controversial. World Health Organization guidelines published in 1999 recommended against ORI in such settings, although recently these guidelines have been reversed for countries with measles mortality reduction goals

Prognosis after aortic valve replacement with a bioprosthesis: predictions based on meta-analysis and microsimulation

BACKGROUND: Bioprostheses are widely used as an aortic valve substitute, but knowledge about prognosis is still incomplete. The purpose of this study was to provide insight into the age-related life expectancy and actual risks of reoperation and valve-related events of patients after aortic valve replacement with a porcine bioprosthesis. METHODS AND RESULTS: We conducted a meta-analysis of 9 selected reports on stented porcine bioprostheses, including 5837 patients with a total follow-up of 31 874 patient-years. The annual rates of valve thrombosis, thromboembolism, hemorrhage, and nonstructural dysfunction were 0.03%, 0.87%, 0.38%, and 0.38%, respectively. The annual rate of endocarditis was estimated at 0.68% for >6 months of implantat

Prognosis after Aortic Valve Replacement with Mechanical Valves and Bioprostheses: Use of Meta-analysis and Microsimulation

Aortic valve replacement (AVR) is a surgical procedure aimed at replacing a diseased aortic valve with a prosthetic device. The prognosis of a patient after AVR depends on many interrelated factors. The objective of this thesis was to further develop and utilize the microsimulation methodology to determine the prognosis of patients after AVR with mechanical valves and bioprostheses, which in turn could assist in the optimal choice of a valve prosthesis for a given patient

Quality Measurement in Orthopaedics: The Purchasers’ View

While all of medicine is under pressure to increase transparency and accountability, joint replacement subspecialists will face special scrutiny. Disclosures of questionable consulting fees, a demographic shift to younger patients, and uncertainty about the marginal benefits of product innovation in a time of great cost pressure invite a serious and progressive response from the profession. Current efforts to standardize measures by the National Quality Forum and PQRI will not address the concerns of purchasers, payors, or policy makers. Instead, they will ask the profession to document its commitment to appropriateness, stewardship of resources, coordination of care, and patient-centeredness. One mechanism for addressing these expectations is voluntary development of a uniform national registry for joint replacements that includes capture of preoperative appropriateness indicators, device monitoring information, revision rates, and structured postoperative patient followup. A national registry should support performance feedback and quality improvement activity, but it must also be designed to satisfy payor, purchaser, policymaker, and patient needs for information. Professional societies in orthopaedics should lead a collaborative process to develop metrics, infrastructure, and reporting formats that support continuous improvement and public accountability
