Managing the replacement cycle of laser inventory.

Area of Science:

• Biomedical Engineering
• Healthcare Technology Management
• Medical Laser Systems

Background:

• Medical lasers are entering a critical replacement phase in technology management.
• Effective management strategies are needed for medical laser technology lifecycles.
• Barnes Hospital sought to formalize its laser replacement process.

Purpose of the Study:

• To define and evaluate a structured process for planned medical laser replacement.
• To leverage existing medical equipment management principles for laser technology.
• To ensure efficient allocation of resources for laser equipment upgrades.

Main Methods:

• A six-step replacement process was developed and implemented.
• The process integrates clinical justification, safety officer review, and committee approvals.
• Quality improvement principles and interdisciplinary teams were utilized.

Main Results:

• The described process systematically guides replacement laser requests from initiation to funding allocation.
• An example from 1993 equipment purchases illustrates the review and approval stages.
• The process involves the Clinical Engineer/Medical Laser Safety Officer, Laser Committee, Laser Users' Group, and Expenditure Authorization Committee.

Conclusions:

• A formalized, multi-step process facilitates effective planned replacement of medical lasers.
• Integrating clinical, technical, and financial reviews optimizes laser technology management.
• This systematic approach supports informed capital expenditure decisions for medical lasers.
