BACKGROUND: Although cannabis may worsen nausea and vomiting for patients with gastroparesis, it may also be an effective treatment for gastroparesis-related abdominal pain. Given conflicting data and a lack of current epidemiological evidence, we aimed to investigate the association of cannabis use on relevant clinical outcomes among hospitalized patients with gastroparesis.

MATERIALS AND METHODS: Patients with a diagnosis of gastroparesis were reviewed from the National Inpatient Sample (NIS) database between 2008 and 2014. Gastroparesis was identified by International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes with patients classified based on a diagnosis of cannabis use disorder. Demographics, comorbidities, socioeconomic status, and outcomes were compared between cohorts using χ and analysis of variance. Logistic regression was then performed and annual trends also evaluated.

RESULTS: A total of 1,473,363 patients with gastroparesis were analyzed [n=33,085 (2.25%) of patients with concomitant cannabis use disorder]. Patients with gastroparesis and cannabis use disorder were more likely to be younger and male gender compared with nonusers (36.7±18.8 vs. 51.9±16.8; P<0.001 and 52.9% vs. 33.5%; P<0.001, respectively). Race/ethnicity was different between groups (P<0.001). Cannabis users had a lower median household income and were more likely to have Medicaid payor status (all P<0.001). Controlling for confounders, length of stay, and mortality were significantly decreased for patients with gastroparesis and cannabis use (all P<0.001).

CONCLUSION: While patients with gastroparesis and cannabis use disorder were younger, with a lower socioeconomic status, and disproportionately affected by psychiatric diagnoses, these patients had better hospitalization outcomes, including decreased length of stay and improved in-hospital mortality.
