METHODOLOGIC 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 in epidemiologic risk assessment.
This paper reviews methodologic issues pertinent to the application of epidemiology in risk assessment and discusses concerns in the presentation of results from such an activity. Assessment of the health risks associated with occupational and environmental exposures involves four phases: hazard identification, i.e., the detection of the potential for agents to cause adverse health effects in e...
متن کاملMethodologic 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 کاملRandomized clinical trials in infancy: methodologic issues.
Randomized clinical trials of early nutritional interventions in infants are necessary to establish safety and efficacy of supplementation of infant formulas with LCPUFAS for term and preterm infants. Such trials pose significant methodologic difficulties when applied to infants because of the rapidly changing development of the infant's central nervous system and its interdependence with multi...
متن کاملMethodologic Issues and Approaches to Spatial Epidemiology
Spatial epidemiology is increasingly being used to assess health risks associated with environmental hazards. Risk patterns tend to have both a temporal and a spatial component; thus, spatial epidemiology must combine methods from epidemiology, statistics, and geographic information science. Recent statistical advances in spatial epidemiology include the use of smoothing in risk maps to create ...
