Según Department of Health, Therapeutic Goods Administration, este evento ( retiro de equipo (recall) ) involucró a un dispositivo médico en Australia que fue producido por Boston Scientific Pty Ltd.

¿Qué es esto?

Una corrección al equipo o acción de retiro tomada por el fabricante para abordar un problema con un dispositivo médico. Los retiros (recalls) ocurren cuando un dispositivo médico está defectuoso, cuando puede poner en riesgo la salud, o cuando simultáneamente está defectuoso y puede poner en riesgo la salud.

    Australian data is current through July 2018. All of the data comes from the Australian Therapeutic Goods Administration, except for the categories Manufacturer Parent Company and Product Classification.
    The Parent Company and the Product Classification were added by ICIJ.
    The parent company information is based on 2017 public records. The device classification information comes from FDA’s Product Classification by Review Panel, based on matches of recall data from the U.S. and Australia.

  • Causa
    Boston scientific has been informed of a single, isolated s-icd event that resulted in a device-related patient death in may of 2017. boston scientific engineers have determined that this patient’s s-icd repeatedly delivered an atypical amount of energy (similar to the arrhythmia induction function) because a specific memory location was corrupted by radiation within the environment. this repeated atypical energy delivery prevented s-icd arrhythmia detection/treatment and ultimately contributed to the patient death. this device behaviour has been simulated in a laboratory setting by corrupting two specific adjacent bits of device memory on similar model s-icds, and the test results correlated with the information available from this event. although this device behaviour is highly unlikely to reoccur, an s-icd software update is being developed to mitigate the effects of memory corruption by preventing atypical energy delivery.
  • Acción
    Boston Scientific are developing a software update (v4.04 or higher) that addresses the behaviour. In the interim, Boston Scientific recommends NO changes to clinical follow-up due to this single event. Specifically, for patients with S-ICD systems: 1. Continue using the S-ICD system to detect and treat life-threatening ventricular tachyarrhythmias; 2. Keep scheduled LATITUDE and/or in clinic follow-ups; and 3. Follow the precautions identified in the S-ICD user’s manual when radiation therapy is prescribed. Furthermore, Boston Scientific does NOT recommend the following: 4. Early or off-cycle follow-ups are not recommended. This type of memory corruption cannot be detected, thus additional S-ICD checks do not reduce the potential for this device behaviour. 5. Prophylactic S-ICD replacement or explant is not recommended. The risks associated with such an additional surgical procedure significantly outweigh the risk of reoccurrence of this device behaviour.

    “We take a patient-first approach to assessing the applicability of every recall and communicate to regulatory bodies in all geographies where the recalled device is sold,” Boston Scientific said in a statement to ICIJ. “We have coordinated several recalls across many countries in a timely manner,” the company said, adding that it complies with all national laws, which can often vary and require different processes for reporting information or taking action on recalls. The company said it uses a rigorous and uniform process to take action on recalls and that “when we initiate a field action (e.g. recall, safety alert), every customer who has received an affected product receives a communication that includes a letter for the physician.”
