This paper presents a conceptual model concerning automatic creation of coherent eLearning experiences through dynamic aggregation of heterogeneous learning objects. The model uses detailed user profiles as the main key to create customized learning content, tailored to each user’s needs, preferences and skills. Aggregation of heterogeneous learning objects may result in a very incoherent learning sequence. Therefore, the model incorporates a method to improve the learning coherence of the generated course. The compromise between customization and coherence is fully adjustable from maximum coherence to maximum customization.

Methods The prevalence of diabetes treated by OHAs was calculated on the basis of: LMS-Health data for Portugal (2003) and two measures of daily drug intake-defined daily dose (DDD) and prescribed daily dose (PDD), after correcting for the proportion of patients treated with two or more OHAs. The PDD and proportion of patients in combination therapies have been obtained in a descriptive, cross-sectional national survey, conducted in 2003, by inquiry of 1046 type 2 diabetics countrywide distributed.
