Pain Scores Are Not Predictive of Pain Medication Utilization

الملخص EN

Objective.

To compare Visual Analogue Scale (VAS) scores with overall postoperative pain medication requirements including cumulative dose and patterns of medication utilization and to determine whether VAS scores predict pain medication utilization.

Methods.

VAS scores and pain medication data were collected from participants in a randomized trial of the utility of phenazopyridine for improved pain control following gynecologic surgery.

Results.

The mean age of the 219 participants was 54 (range19 to 94).

We did not detect any association between VAS and pain medication utilization for patient-controlled anesthesia (PCA) or RN administered (intravenous or oral) medications.

We also did not detect any association between the number of VAS scores recorded and mean pain scores.

Conclusion.

Postoperative VAS scores do not predict pain medication use in catheterized women inpatients following gynecologic surgery.

Increased pain severity, as reflected by higher VAS scores, is not associated with an increase in pain assessment.

Our findings suggest that VAS scores are of limited utility for optimal pain control.

Alternative or complimentary methods may improve pain management.
