BACKGROUND: Heterogeneity exists in reported outcomes and outcome measurement instruments (OMI) from observational studies. A core outcome set (COS) for observational and real-world evidence (RWE) in inflammatory bowel disease (IBD) will facilitate pooling large datasets. This systematic review, describes and classifies clinical and patient-reported outcomes, for COS development.

METHODS: The systematic review of MEDLINE, EMBASE and CINAHL databases, identified observational studies published between 2000 and 2021 using the PEO framework. Studies meeting eligibility criteria were included. After titles and abstracts screening, full-text articles were extracted by two independent reviewers. Primary and secondary outcomes with corresponding OMI were extracted and categorised in accordance with OMERACT Filter 2.1 framework. The frequency of outcomes and OMIs are described.

RESULTS: From 5854 studies, 315 were included: 129 (41%) CD, 60 (19%) UC and 126 (40%) IBD studies with 600,552 participants. 1632 outcomes and 1929 OMI were extracted mainly from medical therapy (181; 72%), surgical (34; 11%) and endoscopic (6; 2%) studies. Clinical and medical therapy-related safety were frequent outcome domains recorded in 194 and 100 studies. Medical therapy related adverse events (n=74) and need for surgery (n=71) were the commonest outcomes. The most frequently reported OMI were patient or event numbers (n=914), Harvey Bradshaw Index (n=45) and Montreal classification (n=42).

CONCLUSIONS: There is substantial variability in outcomes reporting and OMI types. Categorised outcomes and OMI from this review will inform a Delphi consensus on a COS for future RWE in IBD. Data collection standardisation may enhance the quality of RWE applied to decision-making.
