OP-35 monitors patients who visit an emergency department or are admitted to a hospital within 30 days of receiving chemotherapy for one of ten specific conditions:
: Nausea, vomiting, dehydration, fever, and pain.
While appears to be a specific compressed archive file, its contents are not publicly indexed or part of a standard dataset. However, "OP-35" is a significant term in medical quality reporting, often associated with a measure from the Centers for Medicare & Medicaid Services (CMS) .
The primary criticism of OP-35, highlighted in research from institutions like MD Anderson Cancer Center , is its lack of specificity. Critics argue that many "qualifying events" are not actually preventable. For instance, sepsis or severe pneumonia may be inevitable consequences of advanced disease rather than a failure of outpatient management.
