The United States has roughly 6,100 hospitals, according to the American Hospital Association's 2026 Fast Facts, including 5,121 community hospitals and 1,797 rural community hospitals.
Search those thousands of institutions for publicly documented, dedicated MCS hospital protocols and the record becomes remarkably thin.
This investigation could identify three American institutions that historically developed an MCS-specific clinical protocol or procedure.
Not fragrance-free policies.
Not requests for visitors to avoid perfume.
Not generalized disability policies.
MCS protocols.
That distinction matters.
A fragrance-free policy addresses one potential category of exposure. An MCS hospital protocol can reach into admission, emergency care, room preparation, cleaning materials, medications, pharmacy, sterile supplies, medical equipment, linens, food, staff products, transportation through the building and contingency planning if a reaction occurs.
One of the clearest American examples is Southwest General Health Center in Middleburg Heights, Ohio.
Its 2002 Policy 742: Multiple Chemical Sensitivity Syndrome was not a polite sign asking visitors to skip cologne. It established an interdisciplinary system involving physicians, nursing, sterile supply, environmental services, pharmacy, nutritional services, facilities, social services, security and administration.
Before admission, the protocol called for a private room and advance notice to departments including Environmental Services, Central Sterile, Pharmacy and Nutritional Services. The patient's chart was to be flagged for MCS. Staff caring for the patient were instructed to avoid perfume, scented lotions, hairspray, deodorants and similar products. The patient could use a personal respirator; the protocol addressed transportation through the hospital and required measures aimed at limiting exposures from other patients and visitors.
The accompanying hospital policy went further. It addressed sterile linens, latex-free equipment, room cleaning, remodeling near the patient's room, pharmacy ingredients, IV containers and foods.
That is a hospital attempting to redesign the delivery of care around the patient's environmental limitations.
A second surviving document comes from Mercy Medical Center.
Its three-page Multiple Chemical Sensitivity Protocol, dated Nov. 5, 1999, was distributed to patient-care areas, admitting, environmental services, nutritional services and hospital administration. It instructed the emergency department to separate an MCS patient from other patients and visitors and not leave the patient in the general waiting room. It addressed scented staff products, room cleaning, medical equipment, latex, food and medications.
The surviving copy does not clearly identify which Mercy Medical Center issued it, an important limitation in the historical record.
The third documented American example is different.
In 1998, nurses affiliated with Presbyterian Hospital of Dallas published a peer-reviewed paper in the AORN Journal describing the development of a protocol for environmentally sensitive surgical patients. The paper says these patients required highly individualized perioperative assessment and multidisciplinary planning and that the Dallas hospital had successfully cared for such patients.
That is primarily a surgical/perioperative protocol, rather than the broad hospital-wide emergency and admission system preserved from Southwest General or Mercy.
And that creates a question hidden inside the word access.
Even if an operating room can eventually be prepared for a chemically sensitive patient, how does a profoundly affected patient safely travel there, enter the hospital, move through admission, undergo preoperative testing and remain inside long enough to reach that operating room?
The surgery is only one point on the path.
The patient has to survive the path.
