Gabapentin for perioperative pain control in mastectomy
Gabapentin And Breast Surgery Decision Architecture Randomization Trial (GABS-DART) Protocol
This trial will test whether a pre-operative dose of gabapentin reduces pain and opioid use for adults 18–65 having ambulatory mastectomy at Memorial Sloan Kettering.

What this trial studies
This Phase 4 interventional trial randomizes a modification to the pre-operative order set to include gabapentin as part of peri-operative analgesia for patients undergoing ambulatory extended recovery (AXR) mastectomy at MSK. Eligible adults (18–65) having unilateral or bilateral mastectomy at the Josie Robertson Surgical Center will be exposed to the modified order set as part of routine clinical workflow. Key outcomes include postoperative pain scores, opioid consumption, and gabapentin-related adverse events captured through perioperative care. The aim is to see whether making gabapentin a default in the order set improves pain control and reduces opioid use compared with usual ordering.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18–65 scheduled for ambulatory extended recovery (AXR) unilateral or bilateral mastectomy at the Josie Robertson Surgical Center within the MSK system.
Not a fit: Patients older than 65, those not undergoing AXR mastectomy, those with contraindications to gabapentin (for example severe kidney disease or allergy), or those treated entirely outside the MSK system are unlikely to benefit from this protocol.
Why it matters
Potential benefit: If successful, patients could have better post-mastectomy pain control and lower opioid needs, potentially making gabapentin a routine part of peri-operative care.
How similar studies have performed: Previous perioperative studies of gabapentin have shown mixed results for reducing postoperative pain and opioid use, while using order-set default changes as the intervention is a relatively novel implementation approach.
