Cannabis Use and Its Association With Thirty- and Ninety-Day Hospital Readmissions for Patients Admitted for an Inflammatory Bowel Disease Exacerbation
Bibliographic record
Abstract
Background: Though viewed as a potentially safer palliative alternative to opioids, studies of cannabis use for inflammatory bowel disease (IBD) are limited. The impact of opioids on hospital readmissions for IBD has been extensively examined, but cannabis has not been similarly studied. Our goal was to examine the relationship between cannabis use and the risk of 30- and 90-day hospital readmissions. Methods: We conducted a review of all adults admitted for an IBD exacerbation from January 1, 2016 to March 1, 2020 within the Northwell Health Care system. Patients with an IBD exacerbation were identified by primary or secondary ICD10 code (K50.xx or K51.xx) and administration of intravenous (IV) solumedrol and/or biologic therapy. Admission documents were reviewed for the terms "marijuana", "cannabis", "pot" and "CBD". Results: A total of 1,021 patient admissions met inclusion criteria, of whom 484 (47.40%) had Crohn's disease (CD) and 542 (53.09%) were female. Pre-admission cannabis use was reported by 74 (7.25%) patients. Factors found to be associated with cannabis use included younger age, male gender, African American/Black race, current tobacco and former alcohol use, anxiety, and depression. Cannabis use was found to be associated with 30-day readmission among patients with ulcerative colitis (UC), but not among patients with CD, after respectively adjusting each final model by other factors (odds ratio (OR): 2.48, 95% confidence interval (CI): 1.06 - 5.79 and OR: 0.59, 95% CI: 0.22 - 1.62, respectively). Cannabis use was not found to be associated with 90-day readmission on univariable analysis (OR: 1.11, 95% CI: 0.65 - 1.87) nor in the final multivariable model after adjusting for other factors (OR: 1.19, 95% CI: 0.68 - 2.05). Conclusion: Pre-admission cannabis use was found to be associated with 30-day readmission among patients with UC, but not with 30-day readmission for patients with CD nor with 90-day readmission, following an IBD exacerbation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
