Exploring the legacy of African and Indigenous Caribbean admixture in Puerto Rico.

Objectives: From an anthropological genetic perspective, little is known about the ethnogenesis of African descendants in Puerto Rico. Furthermore, historical interactions between Indigenous Caribbean and African descendant peoples that may be reflected in the ancestry of contemporary populations are understudied. Given this dearth of genetic research and the precedence for Afro-Indigenous interactions documented by historical, archeological, and other lines of evidence, we sought to assess the biogeographic origins of African descendant Puerto Ricans and to query the potential for Indigenous ancestry within this community.

Implementing an integrated in-situ coaching, observational audit, and story-telling intervention to support safe surgery.

This article describes an intervention that combined in-situ coaching, observational audits and story-telling to educate theatre teams at University College London Hospitals about the Five steps to safer surgery (NPSA 2010). Our philosophy was to educate theatre teams about 'what goes right' (good catches, exemplary leadership etc) as well as 'what could be improved'. Results showed improvements on 'behavioural reliability' metrics, a 68% increase in near miss reporting and a reduction in surgical harm incidents.
