ABC CCE key terms

The desensitization that occurs when clinicians are exposed to frequent or false device alarms, causing slower or missed responses to genuine alerts; managed through alarm customization, default revision, and policy-based monitoring.

A structured, multidisciplinary set of policies and practices for setting alarm limits, defining escalation, training staff, and monitoring alarm performance across a facility's monitored devices.

The routing of device alarm signals into a central station, nurse call system, or secondary notification device so the right caregiver is notified without relying on sound traveling through walls.

Scheduled inspection, testing, and servicing performed at defined intervals to keep equipment safe and functional and to detect deterioration before it causes failure.

Repair work performed after a device fails or is found defective, restoring it to safe operating condition and documenting the fault, parts, and outcome.

The process of logging, prioritizing, assigning, tracking, and closing maintenance requests so that service history and labor are recorded against each asset.

The authoritative record of every device owned or serviced, including identifiers, location, service history, and risk classification, used to plan and audit maintenance.

A scoring method that assigns equipment to maintenance schedules based on harm potential, use environment, and failure consequences rather than repairing every item on an identical interval.

The average operating time between successive failures of a device or population, used to judge reliability and adjust maintenance intervals or replacement decisions.

The annual process of forecasting equipment needs, justifying purchases with clinical and financial data, and sequencing replacement within budget constraints.

The full expense of an asset across its life, including purchase, installation, consumables, service contracts, training, utilities, and disposal, not just the sticker price.

The sum of acquisition, operation, maintenance, and end-of-life costs used to compare options and decide when replacement is cheaper than continued repair.

Reviewing and negotiating vendor service agreements so that coverage, response times, exclusions, and uptime guarantees match the facility's actual risk and needs.

A contractual commitment that equipment will be available for clinical use a specified percentage of time, often with remedies or credits if availability falls short.

A department-run maintenance and repair capability, staffed and equipped internally, chosen instead of or alongside vendor service to control cost and response time.

A structured evaluation of a technology's clinical effectiveness, safety, cost, and organizational impact used to inform adoption, replacement, and disinvestment decisions.

The pre-purchase review of a proposed device covering clinical need, interoperability, cybersecurity, serviceability, and regulatory status before approval.

Any device that exchanges data over a network, creating exposure to remote access, malware, and configuration drift that must be managed like other connected assets.

A systematic review of a device's vulnerabilities, network exposure, and potential patient harm used to prioritize patching, segmentation, and monitoring controls.

Dividing a network into isolated zones so that a compromised device or system cannot freely reach other devices, clinical systems, or business data.

The ability of devices and information systems to exchange and correctly interpret data using agreed standards, enabling safe automated workflows and records.

A family of standards governing the format and exchange of clinical and administrative messages between hospital systems such as admission, order, and results feeds.

Middleware that translates, routes, and monitors messages between disparate systems, and whose failures can silently stop data flow to or from devices.

A globally unique code on a device label that identifies its model and production lot, supporting recalls, inventory accuracy, and adverse event reporting.

A manufacturer or regulator action to remove or correct a device that poses a health risk, requiring identification of affected units and documented follow-up.

A manufacturer-initiated action taken outside the factory to reduce risk from a device already in use, such as software updates, relabeling, or retrieval.

The documented notification of device-related harm or potential harm to the manufacturer and regulator so that trends can be detected and hazards corrected.

An unexpected occurrence involving death or serious harm that triggers immediate investigation and root cause analysis rather than routine handling.

A structured retrospective method for identifying the underlying system failures and contributing factors behind an incident so that recurrence is prevented.

A prospective team method that lists how a process or device could fail, scores severity, likelihood, and detectability, and targets the highest-risk steps for redesign.

Measurement of leakage current, grounding integrity, and insulation on equipment to confirm it will not deliver harmful current to patients or staff.

The portion of a device designed to come into physical contact with the patient, which determines the electrical safety classification and allowable leakage limits.

Current that could flow through a patient connected to a device under normal or single-fault conditions, kept below defined limits by design and testing.

Documented verification that a staff member can safely perform assigned tasks, typically through observation, testing, and periodic reassessment.

A process of comparing required skills against current staff capability to identify gaps and design targeted education rather than generic instruction.

Short, focused instruction delivered to clinical staff at the point of use, often after a new device is introduced or a use error is identified.

Designing devices and workflows around real user capabilities and limits so that use errors are prevented or made obvious rather than blamed on the operator.

A failure in the interaction between user, device, and environment that produces an unintended outcome, addressed by redesign and training rather than discipline alone.
