Introduction:
We, the undersigned, hereby petition hospitals, surgery centers, and medical/dental professionals worldwide to adopt a new standard of care that includes routine screening for metal hypersensitivity reactions and ensuring informed consent regarding foreign body placement. These measures are crucial in ensuring patient safety and well-being, as metal allergies are more prevalent than commonly recognized. By implementing these screening protocols and emphasizing informed consent, healthcare facilities can proactively identify at-risk patients, mitigate complications, and empower patients in their healthcare decision-making process.

Petition Statement:
We urge the medical industry to recognize the significance of metal hypersensitivity reactions and their impact on patient outcomes. By incorporating routine metal hypersensitivity screening and ensuring informed consent for foreign body placement, healthcare providers can prioritize patient safety, enhance communication, and improve overall surgical experiences.

Reasoning:
1. High Prevalence of Nickel Allergy:
   - According to the Journal of the American Academy of Dermatology, approximately 14% of the general population is allergic to nickel, a common component found in various metal alloys.
   - Nickel allergies can lead to severe dermatological, as well as systemic reactions and complicated outcomes from surgical procedures.

2. Reactivity to Other Metal Alloys:
   - Studies published in the Canadian Medical Association Journal have shown that patients commonly exhibit hypersensitivity reactions to other metal alloys, including cobalt-chromium and stainless steel (which also contains nickel).
   - Failure to identify these allergies may result in post-operative complications, widespread chronic pain and co-morbidities, diminished quality of life for patients as well as significantly greater demands on all resources and personnel within the healthcare system. 

3. Unrecognized Titanium Allergies:
   - Although titanium is generally considered biocompatible, patients can develop allergies to titanium alloys.
   - The Journal of Biomedical Materials Research has reported cases of delayed hypersensitivity reactions to titanium, emphasizing the need for increased awareness among medical professionals.

4. Type-IV Antigen-Driven Delayed Hypersensitivity Reactions:
   - It is crucial to highlight that many metal hypersensitivity reactions present as type-IV, antigen-driven, delayed hypersensitivity reactions.
   - This type of reaction occurs when the immune system recognizes metal particles as foreign antigens, leading to a delayed inflammatory response.
   - These reactions can manifest months or even years after surgery, making their identification challenging without routine metal hypersensitivity screening.

5. Adverse Reactions to Surgical Hardware:
   - Metal hypersensitivity reactions can occur in response to various hardware used in routine surgeries, including surgical clips, staples, biopsy markers, stents, tendon anchors, orthopedic hardware, dental implants, orthodontic materials and joint replacements.
   - Patients with undiagnosed metal allergies may experience complications, implant failure, and prolonged recovery periods.

6. Informed Consent Regarding Foreign Body Placement:
   - We petition for healthcare providers to ensure that patients are fully informed when a foreign body is to be placed and left inside as part of a surgical or medical procedure.
   - Patients must be provided with clear and comprehensive information about the nature of the foreign body, the associated risks, and the potential benefits.
   - Informed consent discussions should include the possibility of metal hypersensitivity reactions and the importance of routine metal hypersensitivity screening.

Call to Action:
We implore hospitals, surgery centers, and medical professionals to take the following actions:

1. Implement Routine Metal Hypersensitivity Screening:
   - Incorporate metal hypersensitivity screening as part of the standard pre-operative assessment for all patients.
   - Utilize cost-effective and accessible screening methods, such as patch or LTT-Lymphocyte Transformation testing to identify potential allergies to common metals used in surgical procedures.

2. Educate Medical Professionals:
   - Provide comprehensive training and educational resources to healthcare providers regarding the range of metals that can trigger hypersensitivity reactions, including type-IV delayed hypersensitivity.
   - Promote awareness of the prevalence of nickel and other metal allergies among the general population.

3. Enhance Patient Communication:
   - Encourage patients to disclose any prior metal-related allergic reactions, such as those caused by jewelry, watch bands, or clothing snaps.
   - Foster an environment of open communication and trust, enabling patients to provide accurate medical histories.

4. Post-operative Patient Awareness:
   - Educate patients about the symptoms associated with metal hypersensitivity reactions, including delayed hypersensitivity reactions that can occur months or even years after surgery.
   - Empower patients to seek prompt medical attention if they suspect an allergic reaction.

5. Comprehensive Screening for Hardware:
   - Acknowledge that metal hypersensitivity reactions can occur in response to hardware used in routine surgeries, such as surgical clips, staples, biopsy markers, stents, tendon anchors, dental implants and orthodontia, orthopedic hardware, and joint replacements.
   - Ensure that screening protocols encompass the full spectrum of potential allergenic materials used in medical devices.

6. Informed Consent for Foreign Body Placement:
   - Emphasize the importance of obtaining informed consent from patients when placing and leaving foreign bodies inside post-operatively.
   - Healthcare providers should provide comprehensive information about the nature, risks, and benefits of foreign body placement, including the possibility of metal hypersensitivity reactions.
   - Patients must have a clear understanding of the procedure and be actively involved in the decision-making process.

Conclusion:
By implementing routine metal hypersensitivity screening and ensuring informed consent regarding foreign body placement, the medical industry can demonstrate its commitment to patient safety, improve surgical outcomes, and alleviate needless suffering caused by metal allergies. We urge hospitals, surgery centers, and medical/dental professionals to recognize the importance of these measures, which will significantly benefit patients and enhance the quality of care provided.

Note: This online petition will be shared globally to gather support and raise awareness among patients, medical/dental professionals, and healthcare institutions. Together, we can make a difference in patient care and advocate for a safer healthcare environment for all.
