The data consist of voluntary reports since June 1993, user facility reports since 1991, distributor reports since 1993, and manufacturer reports since August 1996, and is open for public view. Two private companies have also recently started providing access to analyzed adverse event information: Clarimed provides adverse event information for medical devices and AdverseEvents provides adverse event data for drugs.

sudden death would be considered AEs. In this case, the skin irritation would be classified as not serious, unexpected, and possibly study-related. The death would be classified as serious and unexpected (unless the patient was already at death's door). The local researcher would use his/her medical judgment to determine whether the death could have been related to the study device.

For example, while a study that tests the effectiveness of a new blood pressure cuff for a period of 10 minutes might seem innocuous, the potential exists for the patient's skin to be irritated by the device. Patients in that study might also die during that 10-minute period. Both skin irritation and

As there is a lack of consensus on how AEs should be assessed, there is a concern that the kinds of questions and the phrasing of questions may lead to measurement error and impede comparisons between studies and pooled analysis. However, Allen et al. concluded that the impact of the AE detected by

The type of method used to elicit AEs reported by individuals for evidence on likely adverse drug reactions (ADRs) influences the extent and nature of data. A 2018 review conducted found that some participants in clinical drug trials were asked simple open questions (i.e. 'how are you feeling?'),

Both the skin irritation and the death are unexpected events, and should alert the researcher to the potential existence of a problem with the device (for instance, it could have malfunctioned and shocked the patient). The researcher would report these AEs to the local

An adverse event can also be declared in the normal treatment of a patient which is suspected of being caused by the medication being taken or a medical device used in the treatment of the patient.

All clinical trials have the potential to produce AEs. AEs are classified as serious or non-serious; expected or unexpected; and study-related, possibly study-related, or not study-related.
