Infusing biologic agents, such as infliximab and vedolizumab, for the treatment of IBD in a patient's home is becoming increasingly common. Smaller studies have raised concern about the safety of infusing biologic agents at home. However, the large-scale national experience with safety of home infusions has not been reported. Additionally, the patient experience with home infusions is unknown. Therefore, we conducted a mixed-methods study to better understand home infusions of infliximab and vedolizumab for patients with IBD.

Post-traumatic stress (PTS) is a chronic psychological reaction to an event where the person experiences actual or perceived threat to life or bodily harm. PTS symptoms include nightmares, flashbacks, irritability or low mood, feeling keyed up or on edge, and avoiding situations that trigger trauma memories.

Before this study, only one study on PTS and IBD, with 140 patients, had been conducted in the US. In the previous study, a much higher than expected proportion of patients (32%) reported moderate to severe symptoms of PTS. Because of the nature of IBD and its treatment, researchers aimed to see if there was a similar proportion of PTS in a larger patient sample through IBD Partners and to see how PTS symptoms are related to patient outcomes.

Researchers measured PTS symptoms in a large study of 797 participants using a standard symptom questionnaire and collected other data from IBD Partners including IBD disease activity, hospitalizations, surgeries, and quality of life. Researchers then looked at relationships between PTS symptom severity and each of these important IBD metrics. As expected, PTS was associated with more severe IBD, increased hospitalizations and surgeries, and increased anxiety, depression, fatigue, and pain impact in daily life. Researchers also found women, and racial and ethnic minorities were disproportionally affected by PTS.
