The ethical basis for decision-making in research ethics committees The research ethics committee bases its decisions about the research that it reviews on a coherent and consistent application of the ethical principles that are articulated in international guidance documents and human rights instruments order 250mg grifulvin v, as well as on any national laws or policies consistent with those principles order 125 mg grifulvin v fast delivery. Decision-making procedures for research ethics committees Decisions on research protocols are based on a thorough and inclusive process of discussion and deliberation purchase grifulvin v 125 mg with amex. Written policies and procedures Written policies and procedures include specification of the membership of the research ethics committee, commit- tee governance, review procedures, decision-making, communications, follow-up and monitoring, documentation and archiving, training, quality assurance, and procedures for coordination with other research ethics committees. Sharing information on current practice in health research: some examples Health Research Web (www. The platform uses an editable wiki-type format so that institutions and agencies can personalize entries to suit their own needs. The information presented includes research policies, priorities, projects, capacities and outputs, as illustrated in the following figure.

In the Americas, the Pan American Health Organization (PAHO) has developed Health Research Web – Americas (www. In Africa, the Tanzanian Commission for Science and Technology (COSTECH) uses the platform to issue public calls for research proposals. With this platform COSTECH can monitor which studies have been supported, see how these respond to national research priorities, check what public resources are allocated to the research, and consult the research findings. Information is presented mainly in the form of structured summaries and systematic reviews.

Since interventions, over periods of 2000, the number of registered clinical trials up to 27 years since regulatory has increased markedly, and there are now more approval than 200 000 records on the ICTRP. Using evidence to develop policy, practice and products Good practice dictates that any fndings that might have an impact on clinical practice, on the development of methods of prevention or treat- ment, or on public policy should be made available to those who wish to use them (81). However, con- veying information is just one part of the process of translating research evidence into health policy and practice, as described in the next section.

These BEHAVIOR differences may reflect the importance of the developmental stage at which dopaminergic deficits occur (11).
