Pay-for-performance (P4P) has been widely used around the world seeking to improve health outcomes, and in Brazil it is the basis of the National Program for Improving Access and Quality (PMAQ). The literature published between 1998 and January 2013 that evaluated the effectiveness of P4P to produce results or patterns of access and quality in health was scrutinized. A total of 138 studies, with the inclusion of a further 41 studies (14 systematic reviews, 07 clinical trials and 20 observational studies) were retrieved and analyzed Among the more rigorous studies, favorable conclusions for P4P were less frequent, whereas observational studies were more favorable to positive effects of P4P on the quality of, and access to, health services. Methodological limitations of observational studies may have contributed to these results, but the range of results is more linked to the conceptual and contextual aspects of the use of the P4P schemes reviewed, the heterogeneity of P4P models and results. P4P can be helpful in promoting the achievement of objectives in health care systems, especially in the short term and for specific actions requiring less effort of health care providers, but should be used with caution and with a rigorous planning model, also considering undesirable or adverse effects.
BACKGROUND: Government interventions are critical to addressing the global tobacco epidemic, a major public health problem that continues to deepen. We systematically synthesize research evidence on the effectiveness of government tobacco control policies promoted by the Framework Convention on Tobacco Control (FCTC), supporting the implementation of this international treaty on the tenth anniversary of it entering into force.
METHODS: An overview of systematic reviews was prepared through systematic searches of five electronic databases, published up to March 2014. Additional reviews were retrieved from monthly updates until August 2014, consultations with tobacco control experts and a targeted search for reviews on mass media interventions. Reviews were assessed according to predefined inclusion criteria, and ratings of methodological quality were either extracted from source databases or independently scored.
RESULTS: Of 612 reviews retrieved, 45 reviews met the inclusion criteria and 14 more were identified from monthly updates, expert consultations and a targeted search, resulting in 59 included reviews summarizing over 1150 primary studies. The 38 strong and moderate quality reviews published since 2000 were prioritized in the qualitative synthesis. Protecting people from tobacco smoke was the most strongly supported government intervention, with smoke-free policies associated with decreased smoking behaviour, secondhand smoke exposure and adverse health outcomes. Raising taxes on tobacco products also consistently demonstrated reductions in smoking behaviour. Tobacco product packaging interventions and anti-tobacco mass media campaigns may decrease smoking behaviour, with the latter likely an important part of larger multicomponent programs. Financial interventions for smoking cessation are most effective when targeted at smokers to reduce the cost of cessation products, but incentivizing quitting may be effective as well. Although the findings for bans on tobacco advertising were inconclusive, other evidence suggests they remain an important intervention.
CONCLUSION: When designing and implementing tobacco control programs, governments should prioritize smoking bans and price increases of tobacco products followed by other interventions. Additional studies are needed on the various factors that can influence a policy's effectiveness and feasibility such as cost, local context, political barriers and implementation strategies.
Traditional teaching suggests that corticosteroids should be avoided during acute infectious episodes for fear of compromising the immune response. However, the outcome benefit shown through steroid administration in early septic shock implies this paranoia may be misplaced. We therefore performed a systematic review of the literature to identify the current strength of evidence for the use of corticosteroids in specified infections, and to make appropriate graded recommendations.
