Postsurgical Medication Awareness, Recovery, and Tracking using a Phone-Based App (SMART-APP): a randomized clinical trial
Primary resultResult — go to the resultRatio of geometric means 1.21 95% CI 0.87–1.69Authors' conclusion
Neither a patient-facing educational app nor a clinician-facing decision support tool reduced self-reported opioid consumption among surgical patients with low post-discharge opioid requirements.

Primary result
As reported in the abstract
Ratio of geometric means
1.21
95% CI 0.87–1.69
P = 0.264
By group
Educational app vs Control app
ratio of geometric means 1.21 (95% CI 0.87–1.69); P = 0.264
Secondary outcomes
Opioids prescribed at discharge
- Median (Q1, Q3) 75 (60, 150) morphine milligram equivalents (MME) in both groups
Clinician-facing electronic decision-support tool (second half of trial)
- Did not modify opioid consumption
