Background

The accident took place in the radiotherapy department of the Hospital Clínico Universitario Lozano Blesa, a major healthcare facility in Zaragoza. Radiotherapy is a common treatment for cancer, utilizing high doses of radiation to kill cancer cells and shrink tumors. The equipment used in this process must be precisely calibrated to ensure the safety and effectiveness of the treatment.

The Incident

In December 1990, a malfunction in the radiotherapy equipment led to the administration of excessive doses of radiation to several patients. The error was attributed to a miscalibration of the linear accelerator, a device used to deliver high-energy x-rays or electrons to the region of the patient's tumor.

The miscalibration resulted in patients receiving doses significantly higher than prescribed, causing acute radiation syndrome in some cases. Symptoms of this syndrome can include nausea, vomiting, diarrhea, and in severe cases, damage to internal organs and tissues.

Consequences

The overexposure affected 27 patients, with some experiencing severe health effects. The incident led to the death of at least 11 patients, while others suffered from long-term health complications. The accident highlighted the critical importance of proper equipment maintenance and calibration in medical settings.

Response and Investigation

Following the accident, an investigation was launched to determine the cause and prevent future occurrences. The investigation revealed that the error was due to a combination of human error and equipment malfunction. As a result, new protocols and safety measures were implemented to enhance the safety of radiotherapy treatments.

Impact

The Zaragoza radiotherapy accident had a profound impact on the field of medical physics and radiotherapy. It underscored the need for rigorous safety standards and regular equipment checks. The incident also led to increased awareness and training for medical staff involved in radiotherapy.
