[The epidemiological approach to health inequalities at the local level].

What are the advantages and limitations of epidemiology for decreasing health inequalities at the local level? To answer this question, the current article discusses the role of epidemiology. The hypothesis is that epidemiology produces useful knowledge for local management of interventions aimed at reducing health inequalities, expressed in spaces built by human communities through social and historical processes. Local production of epidemiological knowledge should support action by social actors in specific situations and contexts, thus renewing the appreciation for ecological designs and georeference studies. Such knowledge output and application are also an organizational phenomenon. Organizations can be seen as "conversational networks". In conclusion, strategic and communicative actions by health workers should provide the central thrust for defining new health care and management models committed to decreasing health inequalities, with epidemiology playing a key role.

A review finds that multicenter studies face substantial challenges but strategies exist to achieve Institutional Review Board approval.

BACKGROUND AND OBJECTIVES: To characterize the impact of multiple Institutional Review Board (IRB) reviews on multicenter observational research studies, and identify strategies for overcoming the identified challenges. MATERIALS AND METHODS: Using PubMed, we identified empirical studies, anecdotal reports, and opinion pieces addressing the process of obtaining initial IRB approval for multicenter clinical trials and observational studies. We also reviewed relevant information from federal and other national sources. RESULTS: A total of 40 peer-reviewed articles were synthesized, plus six reports from commissions or other key sources. These sources identified numerous challenges that researchers may encounter when multicenter studies undergo review by multiple IRBs, such as added time for initial review and approval and different requirements across IRBs. Strategies to alleviate these challenges include planning to accommodate multiple reviews and determining upfront whether certain variations to study protocols are tolerable across sites. Many researchers and commissions have proposed comprehensive reforms, such as centralized review for multicenter projects. CONCLUSION: Policy-makers, researchers, and IRBs should convene to specifically discuss optimal approaches for multicenter review. However, until structural changes are implemented, observational researchers should develop and implement strategic plans for obtaining IRB approval in multicenter studies, including adopting models successfully employed by clinical trials.
