Y2K: effects on pacemaker and implantable defibrillator programmers

Area of Science:

• Biomedical Engineering
• Medical Device Technology
• Health Informatics

Background:

• The transition to the year 2000 (Y2K) raised concerns about the functionality of medical devices.
• Permanent pacemakers and implantable defibrillators (PPM/ICDs) utilize internal clock functions that could potentially be affected by Y2K.
• Device programmers are essential for managing and interrogating PPM/ICDs, making their Y2K compliance critical.

Purpose of the Study:

• To assess the Y2K compliance of permanent pacemakers and implantable defibrillator programmers.
• To identify potential issues with date and time stamping on reports generated by PPM/ICD programmers.
• To provide recommendations for managing non-compliant PPM/ICD programmers.

Main Methods:

• Tested 14 different types of PPM/ICD programmers using 8 standardized Y2K compliance tests.
• Evaluated the ability of programmers to handle date rollovers, particularly from December 31, 1999.
• Categorized programmers based on Y2K compliance status.

Main Results:

• All permanent pacemakers and implantable defibrillators (PPM/ICDs) tested were found to function as programmed, irrespective of the Y2K date.
• Five out of 14 PPM/ICD programmer models successfully passed all Y2K compliance tests.
• The most frequent failure involved the programmer's inability to roll the date forward from December 31, 1999, when powered off.

Conclusions:

• PPM/ICDs themselves are not at risk due to Y2K.
• Organizations must proactively test and manage PPM/ICD programmers for Y2K compliance.
• Non-compliant programmers require specific protocols, such as manual date verification, to ensure accurate data recording and device management.
