Background
Little is known about how well postoperative pain is managed in living liver donors, despite pain severity being the strongest predictor of persistent pain with long-lasting disability.
Methods
We conducted a prospective multicenter study of 172 living liver donors. Self-reported outcomes for pain severity, activity interference, affective (emotional) reactions, adverse effects to treatment, and perceptions of care were collected using the American Pain Society Patient Outcomes Questionnaire-Revised. Mixed effects linear regression was used to identify demographic and psychosocial predictors of subscale scores.
Results
Donors were young (36.8±10.6) and healthy. Of 12 expert society analgesic recommendations for postoperative pain management, 49% received care conforming to 3 guidelines, and only 9% to 4 or 5. More than half reported adverse effects to analgesic treatment for moderate to severe pain that interfered with functional activity; however, emotional distress to pain was unexpectedly minimal. Female donors had higher affective (Beta=0.88, p=0.005) and adverse effects scores (Beta=1.33, p<0.001). Donors with 2 or more medical concerns prior to surgery averaged 1 unit higher pain severity, functional interference, adverse effects, and affective reaction subscale scores (Beta range 1.06–1.55, all p<0.05). Receiving information about pain treatment options increased perception of care subscale scores (Beta=1.24, p=0.001), while depressive symptoms before donation were associated with lower scores (Beta=-1.58, p=0.01).
Conclusions
Donors have a distinct profile of pain reporting that is highly influenced by psychological characteristics. Interventions to improve pain control should consider modifying donor behavioral characteristics in addition to optimizing pain care protocols.
