Can you tell the difference between an adverse event following immunization or AEFI and an adverse vaccine reaction? Background rates of vaccine adverse reactions worldwide are published by WHO.
Are you a US healthcare provider?
Background rates differ from country to country because of differences in national surveillance systems. Understanding the background rates in a specific population is useful for monitoring the sensitivity of the AEFI surveillance system in detecting changes in the frequency of vaccine reactions. For example, using the background rate in comparison to the observed rate can be helpful to determine the reaction rate of a vaccine see graphic.
Any increase in the frequency of AEFIs should alert you to consider the quality of the vaccine and whether there are special risks in local populations. In addition, knowing when vaccine reactions may appear time to onset Time to onset The period of time between an intervention in this case, a vaccination and the onset of an adverse reaction to the vaccine. Knowing the background rates in your population is essential in detecting changes in the frequency of vaccine reactions and identifying trends of concern, such as rates reported by AEFI surveillance that are higher than expected.
Adverse events: Frequency and severity Under recommended conditions, vaccines should cause no adverse events and completely prevent the infection that they target. Key point Vaccine adverse events are expected to occur with a certain frequency. It is a long, hard battle for a patient to receive compensation, and a decision in their favour is far from certain. So when the adverse event is the result of an institutional problem, where should a patient turn for compensation or reparation? Would a government no-fault compensation system be helpful? Another issue of concern is what patients say is a lack of recognition and apology from the healthcare institution when they suffer an adverse event, and the lack of information they receive when an unexpected event happens.
Why are institutions so reluctant to inform patients and their families? Would this not be the best first step to improving the situation? This month, Hinnovic presents various issues related to adverse events, from the importance of improving quality in healthcare to the development of technologies and strategies aimed at limiting the number of preventable accidents.
We also touch on the legal side with the presentation of an outline for a government no-fault compensation system. An adverse event is a negative consequence of care that results in unintended injury or illness that may or may not have been preventable.
A preventable adverse event is an avoidable event in the particular set of circumstances. An unpreventable adverse event is an adverse event resulting from a complication that cannot be prevented given the current state of knowledge. An error is a failure of a planned action to be completed as intended or use of a wrong plan to achieve an aim. An active error is an error that occurs at the level of the frontline operator and whose effects are felt almost immediately.
A latent error is an error in design, organization, training or maintenance that leads to operator errors and whose effects typically lie dormant in the system for a lengthy period of time. Washington D.

Definitions and Types of Patient Harm Investigators in the Harvard Medical Practice Study defined an adverse event as "an injury that was caused by medical management rather than the underlying disease and that prolonged the hospitalization, produced a disability at the time of discharge, or both. Controversies Studies of the epidemiology of adverse events, such as a recent series of reports by the Office of the Inspector General, use a two-stage record review process in which patient charts are independently reviewed by two clinically experienced reviewers in order to determine whether an adverse event occurred and if so, whether it was preventable.

Current Context In summary, adverse events refer to harm from medical care rather than an underlying disease. Important subcategories of adverse events include: Preventable adverse events: those that occurred due to error or failure to apply an accepted strategy for prevention; Ameliorable adverse events: events that, while not preventable, could have been less harmful if care had been different; Adverse events due to negligence: those that occurred due to care that falls below the standards expected of clinicians in the community.
Two other terms define hazards to patients that do not result in harm: Near miss: an unsafe situation that is indistinguishable from a preventable adverse event except for the outcome. A patient is exposed to a hazardous situation, but does not experience harm either through luck or early detection. Error: a broader term referring to any act of commission doing something wrong or omission failing to do the right thing that exposes patients to a potentially hazardous situation.
