Relationship of pain relief with catastrophizing following interventional pain procedures for low back pain
Authors' conclusion
PCS showed non-significant improvement following steroid injections; the study was not powered for this outcome. Follow-up PCS scores were predicted by the REM domain of BPI, rather than pain severity.
Study context
- Population
- Patients undergoing fluoroscopic-guided steroid injections for chronic low back pain (cLBP)
- Participants
- 128 patients
- Outcome
- Change in PCS scores from pre-injection to post-injection
- Follow-up
- 1 month
Main finding
As reported in the abstract
PCS (Pain Catastrophizing Scale) score
- Pain Catastrophizing Scale (PCS) at baseline, mean (SD)
- 22.38 (±13.58)
- PCS at 1-month follow-up, mean (SD)
- 19.76 (±15.25)
- Change in PCS pre- to post-injection not significant
- p=0.12
Observational data: associations, not effects.
Further findings
Pain severity (Brief Pain Inventory (BPI))
- Pain severity at baseline, mean (SD)
- 5.56 (±1.82)
- Pain severity at follow-up, mean (SD)
- 4.42 (±2.38)
Predictors of change in PCS (multiple regression)
- Baseline PCS and Relationships, Enjoyment, and Mood (REM) domain of BPI most important predictors
- Pain severity, activity-related pain, age, sex, insurance status, depression, prior surgery, opioid use, prior interventions did not predict change in PCS
Correlation of change in PCS with pain
- Change in PCS moderately correlated with change in pain
- r=0.38
- Weakly correlated with baseline pain in all pain domains
