Methodologic issues in injury case-control studies.
In this paper some methodological problems particularly relevant to case-control studies of injury are illustrated by reference to previous childhood injury case-control studies. In contrast to studies of disease, where 'person time' constitutes the observational experience of interest, in injury studies person time engaged in a particular activity to often more appropriate. The implications fo...
متن کاملMETHODOLOGIC ISSUES A new paradigm of injury intentionality
Objective—To improve understanding of processes leading to injury and assess more specifically the degree of intentionality. Methods—A new paradigm was developed that characterizes the act of inflicting injury (self, other, not inflicted) and the motive. Motives are determined for the act of injury and for the outcome. To test this, 986 cases of adolescent injuries in seven hospitals were revie...
متن کاملMETHODOLOGIC ISSUES Practical introduction to record linkage for injury research
s, and EMS data initially using a deterministic computer program, but when Automatch became available, the latter was found easier to specify and generalize. Hospital readmissions for injury in New Zealand were more easily identified by probabilistic methods, which allowed for more variables to be used for linkage than a deterministic method, even when some values were missing or erroneous. The...
متن کاملMETHODOLOGIC ISSUES An overview of the injury severity score and the new injury severity score

Design—Descriptive analysis and assessment of the distribution of these scales. Methods—Three data sources—the National Pediatric Trauma Registry; the Massachusetts Uniform Hospital Discharge Data Set; and a trauma registry fr...
متن کاملMethodologic problems and standards in case-control research.
IN SUCH scientific domains as physics, chemistry, and biology, rigorous standards have been developed for proving the claim that a particular effect occurs as a consequence of a particular cause. The investigator is asked to perform an experiment, imposing the alleged causal agent. and contrasting its effects with those that follow the imposition of a comparative agent. or ‘control’. In the dom...
