Metal hypersensitivity screening among frontline healthcare workers-A descriptive study

Area of Science:

• Medical device safety
• Immunology
• Healthcare professional education

Background:

• Metal hypersensitivity is a T-cell-mediated reaction linked to adverse events from implanted medical devices.
• Delayed healing, implant failure, and restenosis are potential consequences for patients with metal hypersensitivity.
• Current allergy assessments often omit metal hypersensitivity, despite its clinical significance.

Purpose of the Study:

• To evaluate allergy screening practices for metal hypersensitivity.
• To gauge awareness of metal hypersensitivity among healthcare workers.
• To identify barriers to implementing metal hypersensitivity screening in clinical settings.

Main Methods:

• A cross-sectional, descriptive study utilizing the STROBE checklist.
• Online questionnaires distributed to frontline healthcare workers via professional networks and social media.
• Quantitative data analyzed descriptively; thematic analysis used for implementation barriers.

Main Results:

• 345 participants from 14 countries completed the survey; most practiced in Canada.
• 90% of participants did not routinely inquire about metal hypersensitivity during allergy assessments.
• 86% were unaware of the link between metal hypersensitivity and poor patient outcomes; 81% were willing to incorporate new evidence.

Conclusions:

• Lack of awareness is the primary reason metal hypersensitivity is not routinely included in allergy assessments.
• Barriers to implementation include 'Standards of Practice,' 'Knowledge,' and 'Futility of Screening.'
• Educational interventions are crucial to improve screening practices and patient safety.
