|NRC INFORMATION NOTICE 99-32:||THE EFFECT OF THE YEAR 2000 ISSUE ON MEDICAL LICENSEES|
All U.S. Nuclear Regulatory Commission medical licensees.
The U.S. Nuclear Regulatory Commission (NRC) is issuing this information notice to remind all addressees of the potential problems their computer systems and software may encounter as a result of the change to the year 2000. It is expected that recipients will review this information for applicability to their facilities and consider actions, as appropriate, to avoid potential problems. However, suggestions contained in this information notice are not new NRC requirements; therefore, no specific action nor written response is required.
The Year 2000 (Y2K) problem pertains to the potential inability of computers to correctly recognize dates beyond December 31,1999. This problem results from computer hardware and/or software that uses two-digit fields to represent the year. These systems may misread the year 2000 and cause the systems to fail, generate faulty data, or act in an incorrect manner. The Y2K problem has the potential to interfere with the proper operation of any computer system, hardware that is microprocessor-based (embedded software), software, or database.
As discussed in this Information Notice (IN), "Y2K Ready" is defined as a computer system or application that has been determined to be suitable for continued use into the year 2000, even though the computer system or application is not Y2K Compliant. A Y2K Readiness Program is a plan for a facility to become Y2K Ready. "Y2K Compliant" is defined as a computer system or application that accurately processes date/time data (including, but not limited to, calculating, comparing, and sequencing) from, into, and between the years 1999 and 2000, and beyond, including leap-year calculations.
The Y2K problem is urgent because it has a fixed, non-negotiable deadline that is quickly approaching. This matter requires priority attention because of the limited time remaining to assess the magnitude of the problem, assess its associated risks, and implement programs that will achieve a satisfactory resolution of the Y2K problem.
Existing reporting requirements under 10 CFR Part 21 provide for notification to NRC of deficiencies, non-conformances, and failures, such as the Y2K problem in safety-related systems
Examples of systems that may be affected by the Y2K problem include:
- Treatment planning systems
- Dose calibrators
- Embedded systems
- Decay programs
- Radiation monitoring systems
- Dosimeters, dosimetry programs, and readers
- Communication systems
- Surveillance and maintenance tracking systems
To alert licensees and certificate holders to the Y2K problem, NRC issued several INs:
- IN 96-70, "Year 2000 Effect on Computer System Software," on December 24, 1996;
- IN 97-61, "U.S. Department of Health and Human Services Letter, to Medical Device Manufacturers, on the Year 2000 Problem," on August 6, 1997;
- IN 98-30, "Effect of The Year 2000 Computer Problem on NRC Licensees and Certificate Holders," on August 12, 1998;
- IN 99-18, "Update on NRC's Year 2000 Activities for Materials Licensees and Fuel Cycle Licensees and Certificate Holders," on June 14, 1999; and
- IN 99-20, "Contingency Planning for the Year 2000 Computer Problem," on June 25, 1999.
NRC is concerned with the effect that the Y2K computer problem may have on medical licensees. In particular we are concerned with treatment planning systems used in brachytherapy and teletherapy procedures. The Y2K problem may cause treatment planning systems to operate in an incorrect manner. For example, the treatment planning system may incorrectly calculate the activity of the source(s) used in brachytherapy or teletherapy procedure. This could cause an incorrect treatment time to be calculated and lead to a patient receiving an overdose or an underdose of radiation. Additionally, some dose calibrators have been found not to be Y2K Compliant by the manufacturer.
Addressees should contact their treatment planning system and dose calibrator vendors to determine if their systems are Y2K Ready. Further, addressees should verify that their treatment planning systems and dose calibrators are Y2K Ready. The Y2K status of some medical equipment may be found at the U.S. Food and Drug Administration (FDA) website or manufacture's website. In some cases, manufacturers have upgrades available to correct the Y2K problems for these systems, but licensees need to act to determine whether their systems have Y2K problems and obtain the upgrades.
After the transition to the year 2000, your systems should be tested for proper operation before treating a patient.
The list below contains the FDA's potentially high-risk device types that could be subject to Y2K problems. The list includes the section number in Title 21 of the U.S. Code of Federal Regulations where the generic device type is described. While all of the generic device types listed below are not subject to NRC jurisdiction, licensees should consider FDA's guidance that these radiation or radionuclide systems are potentially at risk for a Y2K problem.
892.5050* MEDICAL CHARGED-PARTICLE RADIATION THERAPY SYSTEM*
892.5300* MEDICAL NEUTRON RADIATION THERAPY SYSTEM*
892.5700* REMOTE CONTROLLED RADIONUCLIDE-APPLICATOR SYSTEM*
892.5750* RADIONUCLIDE RADIATION THERAPY SYSTEM*
892.5900* X-RAY RADIATION THERAPY SYSTEM*
FDA also has developed the MedWatch Reporting Database. FDA's MedWatch reporting requirements are stated below:
Mandatory Reports: Any device-related death or serious injury in your facility, you are required to report deaths to FDA and the manufacturer and injuries to the manufacturer only. Please report these problems through procedures established by your facility; identify the report as a Y2K problem.
Voluntary Reports: Any date-related problem that did not cause death or injury but caused unexpected performance, for example, a malfunction that could cause death or serious injury if the problem recurred. We encourage you to report any contradiction between your device findings and those findings claimed by the manufacturer. Please identify your report as a Y2K problem.
|How to Report:||By telephone to 1-800-FDA-1088
By FAX, use Form 3500 to 1-800-FDA-0178
By Mail, use Form 3500, to:
