RESUMO

OBJECTIVE: To provide guidance on how systematic review authors, guideline developers, and health technology assessment practitioners should approach the use of the risk of bias in nonrandomized studies of interventions (ROBINS-I) tool as a part of GRADE's certainty rating process. STUDY DESIGN AND SETTING: The study design and setting comprised iterative discussions, testing in systematic reviews, and presentation at GRADE working group meetings with feedback from the GRADE working group. RESULTS: We describe where to start the initial assessment of a body of evidence with the use of ROBINS-I and where one would anticipate the final rating would end up. The GRADE accounted for issues that mitigate concerns about confounding and selection bias by introducing the upgrading domains: large effects, dose-effect relations, and when plausible residual confounders or other biases increase certainty. They will need to be considered in an assessment of a body of evidence when using ROBINS-I. CONCLUSION: The use of ROBINS-I in GRADE assessments may allow for a better comparison of evidence from randomized controlled trials (RCTs) and nonrandomized studies (NRSs) because they are placed on a common metric for risk of bias. Challenges remain, including appropriate presentation of evidence from RCTs and NRSs for decision-making and how to optimally integrate RCTs and NRSs in an evidence assessment.

RESUMO

BACKGROUND: Pay-for-Performance (P4P) is a payment model that rewards health care providers for meeting pre-defined targets for quality indicators or efficacy parameters to increase the quality or efficacy of care. OBJECTIVES: Our objective was to assess the impact of P4P for in-hospital delivered health care on the quality of care, resource use and equity. Our objective was not only to answer the question whether P4P works in general (simple perspective) but to provide a comprehensive and detailed overview of P4P with a focus on analyzing the intervention components, the context factors and their interrelation (more complex perspective). SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, three other databases and two trial registers on 27 June 2018. In addition, we searched conference proceedings, gray literature and web pages of relevant health care institutions, contacted experts in the field, conducted cited reference searches and performed cross-checks of included references and systematic reviews on the same topic. SELECTION CRITERIA: We included randomized trials, cluster randomized trials, non-randomized clustered trials, controlled before-after studies, interrupted time series and repeated measures studies that analyzed hospitals, hospital units or groups of hospitals and that compared any kind of P4P to a basic payment scheme (e.g. capitation) without P4P. Studies had to analyze at least one of the following outcomes to be eligible: patient outcomes; quality of care; utilization, coverage or access; resource use, costs and cost shifting; healthcare provider outcomes; equity; adverse effects or harms. DATA COLLECTION AND ANALYSIS: Two review authors independently screened all citations for inclusion, extracted study data and assessed risk of bias for each included study. Study characteristics were extracted by one reviewer and verified by a second.We did not perform meta-analysis because the included studies were too heterogenous regarding hospital characteristics, the design of the P4P programs and study design. Instead we present a structured narrative synthesis considering the complexity as well as the context/setting of the intervention. We assessed the certainty of evidence using the GRADE approach and present the results narratively in 'Summary of findings' tables. MAIN RESULTS: We included 27 studies (20 CBA, 7 ITS) on six different P4P programs. Studies analyzed between 10 and 4267 centers. All P4P programs targeted acute or emergency physical conditions and compared a capitation-based payment scheme without P4P to the same capitation-based payment scheme combined with a P4P add-on. Two P4P program used rewards or penalties; one used first rewards and than penalties; two used penalties only and one used rewards only. Four P4P programs were established and evaluated in the USA, one in England and one in France.Most studies showed no difference or a very small effect in favor of the P4P program. The impact of each P4P program was as follows.Premier Hospital Quality Incentive Demonstration Program: It is uncertain whether this program, which used rewards for some hospitals and penalties for others, has an impact on mortality, adverse clinical events, quality of care, equity or resource use as the certainty of the evidence was very low.Value-Based Purchasing Program: It is uncertain whether this program, which used rewards for some hospitals and penalties for others, has an impact on mortality, adverse clinical events or quality of care as the certainty of the evidence was very low. Equity and resource use outcomes were not reported in the studies, which evaluated this program.Non-payment for Hospital-Acquired Conditions Program: It is uncertain whether this penalty-based program has an impact on adverse clinical events as the certainty of the evidence was very low. Mortality, quality of care, equity and resource use outcomes were not reported in the studies, which evaluated this program.Hospital Readmissions Reduction Program: None of the studies that examined this penalty-based program reported mortality, adverse clinical events, quality of care (process quality score), equity or resource use outcomes.Advancing Quality Program: It is uncertain whether this reward-/penalty-based program has an impact on mortality as the certainty of the evidence was very low. Adverse clinical events, quality of care, equity and resource use outcomes were not reported in any study.Financial Incentive to Quality Improvement Program: It is uncertain whether this reward-based program has an impact on quality of care, as the certainty of the evidence was very low. Mortality, adverse clinical events, equity and resource use outcomes were not reported in any study.Subgroup analysis (analysis of modifying design and context factors)Analysis of P4P design factors provides some hints that non-payments compared to additional payments and payments for quality attainment (e.g. falling below specified mortality threshold) compared to quality improvement (e.g. reduction of mortality by specified percent points within one year) may have a stronger impact on performance. AUTHORS' CONCLUSIONS: It is uncertain whether P4P, compared to capitation-based payments without P4P for hospitals, has an impact on patient outcomes, quality of care, equity or resource use as the certainty of the evidence was very low (or we found no studies on the outcome) for all P4P programs. The effects on patient outcomes of P4P in hospitals were at most small, regardless of design factors and context/setting. It seems that with additional payments only small short-term but non-sustainable effects can be achieved. Non-payments seem to be slightly more effective than bonuses and payments for quality attainment seem to be slightly more effective than payments for quality improvement.

RESUMO

Clinical guidelines are based on the best available evidence and produced systematically. In this context, the transparent presentation of the decision-making process from evidence to recommendation is indispensable. The Evidence to Decision (EtD) frameworks for clinical practice recommendations enables guideline panels to structure their approach and make it comprehensible. The EtD frameworks include three main sections: formulating the question, assessing the evidence and "Additional considerations" for each criterion, and drawing conclusions. This article focuses on the selection and operationalization of those criteria of the EtD framework that are relevant for clinical recommendations in guidelines. These include the priority of the problem, benefits and harms, certainty of the evidence, importance of the outcome, balance, resource use, equity, acceptability and feasibility. To make a recommendation, a panel must consider the implication and importance of each of the above judgments. The EtD framework helps ensure consideration of key criteria that determine whether an intervention should be recommended and that judgments are informed by the best available evidence.

RESUMO

INTRODUCTION: Minimum volume standards have been implemented in various countries for quality or safety policies. We present minimum volume standards in an international comparison, focusing on regulatory approaches, selected sets of procedures and thresholds as well as predetermined consequences of non-compliance. MATERIALS AND METHODS: We combined a comprehensive literature search in electronic databases in March 2016 with a hand-search of governmental and related organisations' webpages. We also contacted international experts to verify the information we found in the literature and to obtain additional data. RESULTS: Minimum volume standards have been introduced in different countries predominantly for highly specialized surgical procedures. The same evidence has led to different definitions and ways of implementation of minimum volume standards in Germany, Canada (Ontario), the Netherlands, Switzerland, and Austria. The regulatory approaches to minimum volume standards and the predetermined consequences of non-compliance differ across the countries. CONCLUSION: The sets of procedures for which minimum volume standards and corresponding thresholds have been introduced vary across countries, possibly due to different regulatory approaches. In addition, key attributes of the health care system might affect the development and implementation of minimum volume standards. Therefore, it is not feasible to formulate uniform recommendations that are applicable to all countries. Our results provide a comprehensive overview of international minimum volume standards and can be used to inform policy decisions.

RESUMO

BACKGROUND: The surgeon volume-outcome relationship has been discussed for many years and its existence or nonexistence is of importance for various reasons. A lot of empirical work has been published on it. We aimed to summarize systematic reviews in order to present current evidence. METHODS: Medline, Embase, Cochrane database of systematic reviews (CDSR), and health technology assessment websites were searched up to October 2015 for systematic reviews on the surgeon volume-outcome relationship. Reviews were critically appraised, and results were extracted and synthesized by type of surgical procedure/condition. RESULTS: Thirty-two reviews reporting on 15 surgical procedures/conditions were included. Methodological quality of included systematic reviews assessed with the assessment of multiple systematic reviews (AMSTAR) was generally moderate to high albeit included literature partly neglected considering methodological issues specific to volume-outcome relationship. Most reviews tend to support the presence of a surgeon volume-outcome relationship. This is most clear-cut in colorectal cancer, bariatric surgery, and breast cancer where reviews of high quality show large effects. CONCLUSIONS: When taking into account its limitations, this overview can serve as an informational basis for decision makers. Our results seem to support a positive volume-outcome relationship for most procedures/conditions. However, forthcoming reviews should pay more attention to methodology specific to volume-outcome relationship. Due to the lack of information, any numerical recommendations for minimum volume thresholds are not possible. Further research is needed for this issue.
