What can we learn from consumer reports on psychiatric adverse drug reactions with antidepressant medication? Experiences from reports to a consumer association

Background According to the World Health Organization (WHO) the cost of adverse drug reactions   (ADRs) in the general population is high and under-reporting by health professionals   is a well-recognized problem. Another way to increase ADR reporting is to let the   consumers themselves report directly to the authorities. In Sweden it is mandatory   for prescribers to report serious ADRs to the Medical Products Agency (MPA), but there   are no such regulations for consumers. The non-profit and independent organization   Consumer Association for Medicines and Health, KILEN has launched the possibility   for consumers to report their perceptions and experiences from their use of medicines   in order to strengthen consumer rights within the health care sector. This study aimed   to analyze these consumer reports. Methods All reports submitted from January 2002 to April 2009 to an open web site in Sweden   where anyone could report their experience with the use of pharmaceuticals were analyzed   with focus on common psychiatric side effects related to antidepressant usage. More   than one ADR for a specific drug could be reported. Results In total 665 reports were made during the period. 442 reports concerned antidepressant   medications and the individual antidepressant reports represented 2392 ADRs and 878   (37%) of these were psychiatric ADRs. 75% of the individual reports concerned serotonin-reuptake   inhibitor (SSRI) and the rest serotonin-norepinephrine reuptake inhibitor (SNRI).   Women reported more antidepressant psychiatric ADRs (71%) compared to men (24%). More   potentially serious psychiatric ADRs were frequently reported to KILEN and withdrawal   symptoms during discontinuation were also reported as a common issue. Conclusions The present study indicates that consumer reports may contribute with important information   regarding more serious psychiatric ADRs following antidepressant treatment. Consumer   reporting may be considered a complement to traditional ADR reporting

Creating a medical dictionary using word alignment: The influence of sources and resources

<p>Abstract</p> <p>Background</p> <p>Automatic word alignment of parallel texts with the same content in different languages is among other things used to generate dictionaries for new translations. The quality of the generated word alignment depends on the quality of the input resources. In this paper we report on automatic word alignment of the English and Swedish versions of the medical terminology systems ICD-10, ICF, NCSP, KSH97-P and parts of MeSH and how the terminology systems and type of resources influence the quality.</p> <p>Methods</p> <p>We automatically word aligned the terminology systems using static resources, like dictionaries, statistical resources, like statistically derived dictionaries, and training resources, which were generated from manual word alignment. We varied which part of the terminology systems that we used to generate the resources, which parts that we word aligned and which types of resources we used in the alignment process to explore the influence the different terminology systems and resources have on the recall and precision. After the analysis, we used the best configuration of the automatic word alignment for generation of candidate term pairs. We then manually verified the candidate term pairs and included the correct pairs in an English-Swedish dictionary.</p> <p>Results</p> <p>The results indicate that more resources and resource types give better results but the size of the parts used to generate the resources only partly affects the quality. The most generally useful resources were generated from ICD-10 and resources generated from MeSH were not as general as other resources. Systematic inter-language differences in the structure of the terminology system rubrics make the rubrics harder to align. Manually created training resources give nearly as good results as a union of static resources, statistical resources and training resources and noticeably better results than a union of static resources and statistical resources. The verified English-Swedish dictionary contains 24,000 term pairs in base forms.</p> <p>Conclusion</p> <p>More resources give better results in the automatic word alignment, but some resources only give small improvements. The most important type of resource is training and the most general resources were generated from ICD-10.</p
