Notes: All drug categories are for standing doses of each category. The reference group is no analgesics, and adverse events are adjusted for concomitant medications (steroids, diuretics, antidepressants, anxiolytics, and antipsychotics) and comorbidities (age, sex, race, activities of daily living [ADL] scale score, cognitive performance score [CPS] score, pain frequency, and pain intensity). Data for dehydration not shown because n < 11. Due to the current policy regarding disclosure of Medicare Beneficiary Data and concerns about confidentiality, data for patients with n < 11 are not specified.

LAO = long-acting opioid; SAO = short-acting opioid; OR = odds ratio; CI = confidence interval; GI = gastrointestinal.
