Abstract 17115: Depressive Symptoms Moderate Pain in Cardiac Surgery Patients During Post-Hospital Recovery
Pain is one of the most common problems reported by cardiac surgery patients after hospital discharge. The purpose of this study was to: 1) evaluate pain severity and its effect on daily activities and 2) determine the impact of depressive symptoms on pain in cardiac surgery patients after hospital discharge.
Methods: As part of a clinical trial of depression treatment, 243 cardiac surgery patients (age 67.1 +/- 9.6 years, 27.6% female) completed measures of pain (severity and interference with daily activity subscales of the Brief Pain Inventory), depression (Beck Depression Inventory [BDI]), anxiety (Brief Symptom Inventory), perceived control (Cardiac Attitudes Scale), and social support (Perceived Social Support Scale) at hospital discharge and 6 weeks later. Using RM-ANOVA and controlling for age and baseline pain scores, patterns for pain severity and interference with daily activities were compared in patients with and without depressive symptoms (cutoff < 10 on BDI). Correlates of pain were identified by linear regression modeling with forced entry.
Results: Compared to patients without depressive symptoms (n = 192), those with depressive symptoms (n = 51) had higher baseline and follow-up pain severity and pain interference scores (time × group interactions p < .001, Figure). At 6 weeks post-discharge, after controlling for other psychosocial variables (anxiety, perceived control, and social support), depressive symptoms were independently correlated with both pain severity (p < .001) and pain interference (p < .001) scores. Alone, depressive symptoms explained 8% and 15% of the variance in pain severity and pain interference scores, respectively.
Conclusions: Depressive symptoms are an important moderator of pain after cardiac surgery. Clinicians should consider depression status when planning post-discharge pain management for cardiac surgery patients.
