Background: Surgical mortality data are collected routinely in high-income countries, yet virtually no low-or middle-income countries have outcome surveillance in place. The aim was prospectively to collect worldwide mortality data following emergency abdominal surgery, comparing findings across countries with a low, middle or high Human Development Index (HDI).Methods: This was a prospective, multicentre, cohort study. Self-selected hospitals performing emergency surgery submitted prespecified data for consecutive patients from at least one 2-week interval during July to December 2014. Postoperative mortality was analysed by hierarchical multivariable logistic regression.

It has long been recognized that client learning is an important factor in the successful development of information systems. While there is little question that clients should learn, there is less clarity about how best to facilitate client learning during developer-client meetings. In this study, we suggest that a cooperative learning strategy called collaborative elaboration developed by educational psychologists provides a theoretical and practical basis for stimulating client learning during an IS design process. The problem with assessing the effects of collaborative elaboration, however, is in controlling for the many other factors that might affect client learning and outcomes of an IS design phase. In a unique research opportunity, we were able to measure the use of collaborative elaboration among 85 developers and clients involved in 17 projects over a semester-long IS design process. The projects were homogeneous with respect to key contextual variables. Our PLS analysis suggested that teams using more collab-Majchrzak et al./Managing Client Dialogues During IS Design

Prescribing of proton pump inhibitors has increased sharply each year since 1991. One reason may be that GPs perceive proton pump inhibitors to be more effective than H2-receptor antagonists.
