Enhanced Recovery after Lumbar Spine Fusion: A Randomized Controlled Trial to Assess the Quality of Patient Recovery.

BACKGROUND: Prospective trials of enhanced recovery after spine surgery are lacking. We tested the hypothesis that an enhanced recovery pathway improves quality of recovery after one- to two-level lumbar fusion. METHODS: A patient- and assessor-blinded trial of 56 patients randomized to enhanced recovery (17 evidence-based pre-, intra-, and postoperative care elements) or usual care was performed. The primary outcome was Quality of Recovery-40 score (40 to 200 points) at postoperative day 3. Twelve points defined the clinically important difference. Secondary outcomes included Quality of Recovery-40 at days 0 to 2, 14, and 56; time to oral intake and discharge from physical therapy; length of stay; numeric pain scores (0 to 10); opioid consumption (morphine equivalents); duration of intravenous patient-controlled analgesia use; complications; and markers of surgical stress (interleukin 6, cortisol, and C-reactive protein). RESULTS: The analysis included 25 enhanced recovery patients and 26 usual care patients. Significantly higher Quality of Recovery-40 scores were found in the enhanced recovery group at postoperative day 3 (179 ± 14 vs. 170 ± 16; P = 0.041) without reaching the clinically important difference. There were no significant differences in recovery scores at days 0 (175 ± 16 vs. 162 ± 22; P = 0.059), 1 (174 ± 18 vs. 164 ± 15; P = 0.050), 2 (174 ± 18 vs. 167 ± 17; P = 0.289), 14 (184 ± 13 vs. 180 ± 12; P = 0.500), and 56 (187 ± 14 vs. 190 ± 8; P = 0.801). In the enhanced recovery group, subscores on the Quality of Recovery-40 comfort dimension were higher (longitudinal mean score difference, 4; 95% CI, 1, 7; P = 0.008); time to oral intake (-3 h; 95% CI, -6, -0.5; P = 0.010); and duration of intravenous patient-controlled analgesia (-11 h; 95% CI, -19, -6; P < 0.001) were shorter; opioid consumption was lower at day 1 (-57 mg; 95% CI, -130, -5; P = 0.030) without adversely affecting pain scores (-2; 95% CI, -3, 0; P = 0.005); and C-reactive protein was lower at day 3 (6.1; 95% CI, 3.8, 15.7 vs. 15.9; 95% CI, 6.6, 19.7; P = 0.037). CONCLUSIONS: Statistically significant gains in early recovery were achieved by an enhanced recovery pathway. However, significant clinical impact was not demonstrated.

The Fibromyalgia Survey Score Correlates With Preoperative Pain Phenotypes But Does Not Predict Pain Outcomes After Shoulder Arthroscopy.

OBJECTIVES: Fibromyalgia (FM) characteristics can be evaluated using a simple, self-reported measure that correlates with postoperative opioid consumption after lower-extremity joint arthroplasty. The purpose of this study was to determine whether preoperative pain history and the FM survey score can predict postoperative outcomes after shoulder arthroscopy, which may cause moderate to severe pain. MATERIALS AND METHODS: In this prospective study, 100 shoulder arthroscopy patients completed preoperative validated self-report measures to assess baseline quality of recovery score, physical functioning, depression, anxiety, and neuropathic pain. FM characteristics were evaluated using a validated measure of widespread pain and comorbid symptoms on a 0 to 31 scale. Outcomes were assessed on postoperative day 2 (opioid consumption [primary], pain, physical functioning, quality of recovery score), and day 14 (opioid consumption, pain). RESULTS: FM survey scores ranged from 0 to 13. The cohort was divided into tertiles for univariate analyses. Preoperative depression and anxiety (P<0.001) and neuropathic pain (P=0.008) were higher, and physical functioning was lower (P<0.001), in higher FM survey score groups. The fibromyalgia survey score was not associated with postoperative pain or opioid consumption; however, it was independently associated with poorer quality of recovery scores (P=0.001). The only independent predictor of postoperative opioid use was preoperative opioid use (P=0.038). DISCUSSION: FM survey scores were lower than those in a previous study of joint arthroplasty. Although they distinguished a negative preoperative pain phenotype, FM scores were not independently associated with postoperative opioid consumption. Further research is needed to elucidate the impact of a FM-like phenotype on postoperative analgesic outcomes.
