Behavioral responses and self-reported pain in postoperative patients

Area of Science:

• Nursing
• Pain Management
• Patient Assessment

Background:

• Pain assessment is complex due to its multidimensional nature.
• Accurate pain measurement is crucial for effective patient care, especially for those using patient-controlled analgesia (PCA).
• Existing pain scales may not fully capture the nuances of patient-reported pain.

Purpose of the Study:

• To examine the correlation between nurses' assessment of behavioral pain cues and patients' self-reported pain.
• To compare the effectiveness of the PACU Behavioral Pain Rating Scale (BPRS) against a standard hospital PCA pain scale.
• To validate the BPRS as a tool for measuring pain in postoperative gynecological surgery patients.

Main Methods:

• A descriptive-correlational study design was employed.
• 36 postoperative gynecological surgery patients receiving PCA were recruited.
• Pain was assessed using the PACU Behavioral Pain Rating Scale (BPRS), patient self-report, and the hospital's PCA pain-rating scale within the first 6 postoperative hours.

Main Results:

• Significant positive correlations were found between BPRS scores and patient self-reported pain (rs = 0.56 to 0.80; P < 0.05).
• The hospital's PCA pain rating scale showed a significant relationship with self-reported pain only at the second assessment (rs = 0.45; P < 0.05).
• The BPRS demonstrated a consistent moderate to high relationship with patient self-reports, outperforming the hospital's scale.

Conclusions:

• The PACU Behavioral Pain Rating Scale (BPRS) is a reliable tool for assessing pain in postoperative patients.
• Nurse-based behavioral pain assessment using the BPRS can effectively complement patient self-reporting.
• Improved pain assessment tools are needed to enhance patient outcomes and satisfaction.
