  1. Note: Logistic regression was performed in a stepwise fashion. Initial variables included, age, sex, race, language, immigrant, employment, homelessness, active substance abuse, heavy use of prescription opioids or benzodiazepines, insurance, type of procedure, attendance at pre-operative appointment, history of no-show, type of procedure, and wait-time. Variables that were not statistically significant (p > 0.05) were removed from the regression in a forward stepwise fashion
  2. OR odd ratio, CI confidence interval
  3. aHeavy use of prescription opioids/benzodiazepines was defined as the reported use of prescription opioids or benzodiazepines that was determined to be a hindrance to adequate moderate sedation by the evaluating clinician during the pre-endoscopy GI clinic encounter
