Introduction: Despite increasing treatment opportunities for ulcerative colitis (UC), patients often suffer acute periods of increased disease severity. Since little is known regarding how healthcare resource utilization (HCRU) and drug dosing differ between flaring and non-flaring patients in a real-world clinical setting, we aimed to assess these differences.

Methods: Data were extracted from the Adelphi UC Disease Specific Programme, a point-in-time survey of gastroenterologists and patients conducted in France, Germany, Italy, Spain, UK, and US from January 2020-March 2021. Gastroenterologists provided clinical characteristics, treatment history and HCRU for their next 5-7 consulting UC patients with a history of moderate-severe disease. Patients were categorized based on whether they experienced a flare (last 12 months). Two subgroups were analysed separately, to explore drug dosing patterns for flaring and non-flaring patients, receiving targeted therapies (≥12 months) (TT; biologics, Janus kinase inhibitors) or currently receiving corticosteroids.

Results: This study included 2,019 patients of which 968 (47.9%) were reported by their gastroenterologist to have flared (last 12 months). While age and sex were similar across subgroups, flaring patients had a shorter disease duration (p=0.05) and greater disease extension (p< 0.01) vs non-flaring patients (Table 1). Differences were seen across all HCRU measures with a greater number of consultations (7.2 vs 5.3), hospitalizations (0.4 vs 0.1), biopsies, endoscopies, stool and blood tests in the last 12 months for flaring patients vs non-flaring patients (all p< 0.01). A higher proportion of flaring patients had received corticosteroids in the last 12 months vs non-flaring patients (39.4% vs 13.9%, p< 0.01), and among those currently receiving corticosteroids, 9.9% of flaring patients had their corticosteroid dose escalated vs 5.6% of non-flaring patients (p=0.28). Of those patients receiving their current TT for ≥12 months, 25.7% of flaring patients had their TT dose escalated vs 11.7% of non-flaring patients (p< 0.01).

Discussion: Almost half of patients with UC in our cohort had experienced a flare within the last 12 months. These patients had greater HCRU, increased corticosteroid use, and those on TT were more likely to receive escalated drug doses, highlighting the need for additional treatment options to target disease control, entailing the potential for a reduced burden of flares on UC patients and healthcare systems.
