It differs from most scientific endeavors, which are based on objective techniques, and allows subjective bias to enter the judgement process, explains Dr.
Robert Jeanfreau , owner and principal investigator at clinical research consortium MedPharmics. That is already a biased view. For example, Jeanfreau notes that a clinical investigator could regard a minor decrease in the ratio of volumes of red blood cells to the total volume of blood as an adverse event.
A similar size increase in ratio, however, might not be viewed in the same way. Not only is reporting of AEs prone to biases, it also tends to be underreported. Clinical trial regulations stipulate that researchers must report SAEs immediately to the sponsor, which informs the FDA within 15 days. But Neuer says reporting remains problematic, often not appearing in published articles at all.
Reporting AEs is valuable to pharma companies as they can collect post-marketing safety data. And healthcare professionals are well placed to make these reports. Yet very few do. They used a questionnaire of 43 questions to assess pharmacovigilance knowledge and activities.
Respondents, comprised mainly physicians and nurses, reported that Reasons included that only You do not have to be certain that the medical device caused the adverse event, just suspicious. It may be difficult to determine if a particular medical device has caused the effect in an individual case. When we receive a number of reports with similar events it helps us to determine if the medical device plays a role in the adverse event.
If an issue is related to the quality of a medical device, but no adverse event occurred i. The following events are not considered to be reportable events and need not be reported to Medsafe. Medsafe will not normally investigate such events. All adverse events are reviewed by Medsafe with both safety and quality issues being considered. Any remedial action that arises overseas for devices supplied in Australia must be reported to the TGA Recalls team.
A 'near adverse event' is an occurrence involving a medical device that might have led to a death or serious injury if, for example, the timely intervention of a healthcare practitioner is the only reason a death or serious injury did not occur.
For an event to be defined as a near adverse event, it is sufficient that:. There are eight exemption rules that can apply to the requirement to report an adverse event.
The exemption rules were included in a public consultation on proposed enhancements to adverse event reporting , and may be revised in the future. Regardless of the existence of provisions in the Instruction for Use provided by the manufacturer, deficiencies of devices that will be always detected by the user and where no serious injury has occurred, do not need to be reported. Please note: If the device is used the exemption does not apply - the event must be reported.
When the manufacturer has information that the root cause of the adverse event is due to patient condition, the event does not need to be reported. These conditions could be pre-existing or occurring during device use. To justify not reporting, the manufacturer should have information available to conclude that the device performed as intended and did not cause or contribute to a death or serious injury.
A person qualified to make a medical judgement would accept the same conclusion. The service life is defined as 'the time or usage that a device is intended to remain functional after it is manufactured, placed into use, and maintained as specified'. The service life must be specified by the device manufacturer and included in the master record technical file. When the only cause for the adverse event was that the device exceeded its service life and the failure mode is not unusual, the adverse event does not need to be reported.
Assessment of whether an event is exempt from reporting under this rule must be based on the information in the master record, on the label or in Instructions for Use for the device. Adverse events that did not lead to serious injury or death, because a design feature protected against a fault becoming a hazardous situation in accordance with relevant standards or documented design inputs do not need to be reported.
Adverse events that could lead, but have not yet led, to death or serious injury, but have a remote likelihood of causing death or serious injury, and which have been established and documented as acceptable after risk assessment do not need to be reported. If an adverse event resulting in death or serious injury occurs, the adverse event is reportable and a reassessment of the risk is necessary.
If reassessment determines that the risk remains remote, previous reports of near incidents of the same type do not need to be reported retrospectively. Decisions not to report subsequent failures of the same type must be documented. Please note: A change in the trend usually an increase in frequency of these non-serious outcomes must be reported.
The manufacturer of a pacemaker supplied to the market identified a software bug and determined that the likelihood of occurrence of a serious injury with a particular setting is remote. No patients experienced any adverse health effects. The manufacturer of blood donor sets obtains repeated complaints of minor leaks of blood from these sets. No patient injuries from blood loss or infections of staff have been reported.
The chance of infection or blood loss has been re-evaluated by manufacturer and deemed remote. Expected and foreseeable side effects that are documented in manufacturer's Instructions for Use or labelling. Upon request from FDA, the sponsor must submit to FDA any additional data or information that the agency deems necessary, as soon as possible, but in no case later than 15 calendar days after receiving the request. The sponsor must also notify FDA of any unexpected fatal or life-threatening suspected adverse reaction as soon as possible but in no case later than 7 calendar days after the sponsor's initial receipt of the information.
FDA may require a sponsor to submit IND safety reports in a format or at a frequency different than that required under this paragraph. The sponsor may also propose and adopt a different reporting format or frequency if the change is agreed to in advance by the director of the FDA review division that has responsibility for review of the IND.
A sponsor of a clinical study of a drug marketed or approved in the United States that is conducted under an IND is required to submit IND safety reports for suspected adverse reactions that are observed in the clinical study, at domestic or foreign study sites. The sponsor must also submit safety information from the clinical study as prescribed by the postmarketing safety reporting requirements e.
Study endpoints e. However, if a serious and unexpected adverse event occurs for which there is evidence suggesting a causal relationship between the drug and the event e. A safety report or other information submitted by a sponsor under this part and any release by FDA of that report or information does not necessarily reflect a conclusion by the sponsor or FDA that the report or information constitutes an admission that the drug caused or contributed to an adverse event.
A sponsor need not admit, and may deny, that the report or information submitted by the sponsor constitutes an admission that the drug caused or contributed to an adverse event.
