Unequal Dis.ribution of Innovation Efforts.for Neglected Tropical Dis.as.s. The Role of Funding Evaluation Criteria

引用

Background: International res.arch and innovation efforts.for neglected tropical dis.as.s.have increas.d in recent decades.due to dis.arities.in overall health res.arch funding in relation to global burden of dis.as.. However, within the field of neglected tropical dis.as.s.s.m. s.em.far m.re neglected than others. In this.res.arch the aim.is.to inves.igate the dis.ribution of res.urces.and efforts. as.well as.the m.chanis.s.that underpin funding allocation for neglected tropical dis.as.s. m.thodology: A s.s.em.tic literature review was.conducted to es.ablis. a com.rehens.ve overview of known indicators.for innovation efforts.related to a wide range of neglected tropical dis.as.s. Articles.were s.lected bas.d on a s.bjective evaluation of their relevance, the pres.nce of original data, and the breadth of their s.ope. This.was.followed by thirteen in-depth open-ended interviews.with repres.ntatives.of private, public and philanthropic funding organizations. concerning evaluation criteria for funding res.arch propos.ls. Res.lts. The findings.reveal a large difference in the extent to which the individual dis.as.s.are neglected with notable differences.between abs.lute and relative efforts. Criteria us.d in the evaluation of res.arch propos.ls.relate to potential im.act, the probability of s.cces. and s.rategic fit. Private organizations.prioritize s.rategic fit and econom.c im.act;philanthropic organizations.prioritize s.ort-term.s.cietal im.act;and public generally prioritize the probability of s.cces. by accounting for follow-up funding and involvem.nt of indus.ry. Funding decis.ons.of different types.of organizations.are highly interrelated. Conclus.ons. This.s.udy s.ows.that the evaluation of funding propos.ls.introduces.and retains.unequal funding dis.ribution, reinforcing the relative neglect of dis.as.s. s.cietal im.act is.the prim.ry rationale for funding but application of it as.a funding criterion is.as.ociated with s.gnificant challenges.
