💡Why This Measure Matters

Before you start a patient on biologic anti-TNF therapy for inflammatory bowel disease, you must screen them for hepatitis B. These powerful immune-suppressing drugs can reactivate dormant hepatitis B, causing serious liver disease. Check their HBsAG, HBcAb, or HBsAB status and document the results before the first dose. It's a straightforward safety gate that prevents a potentially life-threatening complication and should be part of every pre-biologic workup.

📖Clinical Rationale

Before initiating biologic anti-TNF therapy for a patient with IBD, it is essential to screen the patient for HBV, as research has documented reactivation of HBV after anti-TNF therapy. This is a patient safety measure. Opportunity for improvement: While there are a limited number of studies that investigate gaps in care for patients with IBD, the research that does exist identifies opportunities for improvement in care areas: 1) there is a lack of adherence to documentation of HBV screening, most noticeably in the use of disease-modifying anti-TNF drugs, and variations in care by practice setting, geographic region and physician specialty.

See FDA package labeling for anti-TNF biological agents — golimumab, certolizumab pegol, infliximab and adalimumab. Reactivation of hepatitis B virus has been reported in patients who are carriers of this virus and are taking TNF blocker medicines. (Kaiser T, Moessner J, McHutchison JG, Tillmann HG. Life threatening liver disease during treatment with monoclonal antibodies.

📝Clinical Recommendations

Infliximab can reactivate latent HBV. (Esteve et al. 2004).

📋Implementation Notes

For the purposes of MIPS implementation, this patient-process measure is submitted a minimum of once per patient for the performance period. The most advantageous quality data code will be used if the measure is submitted more than once. Telehealth
