Implementing Enhanced Recovery After Surgery for hysterectomy in a hospital network with audit and feedback: A stepped-wedge cluster randomised trial

OBJECTIVE

To evaluate the effectiveness of implementing the Enhanced Recovery After Surgery (ERAS) protocol in patients undergoing elective hysterectomy in a network of regional hospitals, supported by an intensive audit-and-feedback (A&F) approach.

DESIGN

A multi-centre, stepped-wedge cluster randomised trial (ClinicalTrials.gov NCT04063072).

SETTING

Gynaecological units in the Piemonte region, Italy.

POPULATION

Patients undergoing elective hysterectomy, either for cancer or for benign conditions.

METHODS

Twenty-three units (clusters), stratified by surgical volume, were randomised into four sequences. At baseline (first 3 months), standard care was continued in all units. Subsequently, the four sequences implemented the ERAS protocol successively every 3 months, after specific training. By the end of the study, each unit had a period in which standard care was maintained (control) and a period in which the protocol, supported by feedback, was applied (experimental).

MAIN OUTCOME MEASURES

Length of hospital stay (LOS), without outliers (>98th percentile).

RESULTS

Between September 2019 and May 2021, 2086 patients were included in the main analysis with an intention-to-treat approach: 1104 (53%) in the control period and 982 (47%) in the ERAS period. Compliance with the ERAS protocol increased from 60% in the control period to 76% in the experimental period, with an adjusted absolute difference of +13.3% (95% CI 11.6% to 15.0%). LOS, moving from 3.5 to 3.2 days, did not show a significant reduction (-0.12 days; 95% CI -0.30 to 0.07 days). No difference was observed in the occurrence of complications.

CONCLUSIONS

Implementation of the ERAS protocol for hysterectomy at the regional level, supported by an A&F approach, resulted in a substantial improvement in compliance, but without meaningful effects on LOS and complications. This study confirms the effectiveness of A&F in promoting important innovations in an entire hospital network and suggests the need of a higher compliance with the ERAS protocol to obtain valuable improvements in clinical outcomes.

Acupoint Stimulation for Pain Control in Enhanced Recovery After Surgery: Systematic Review and Meta-Analysis

Introduction: Postoperative pain control is a challenge in enhanced recovery after surgery (ERAS). The current study reviewed the efficacy and safety of incorporating acupoint stimulation for postoperative pain control in ERAS. Methods: Ten databases for relevant randomized controlled trials (RCTs) published in English or Mandarin Chinese were searched from 1997 to 2022. The quality of each article was appraised using the Cochrane Collaboration Risk of Bias Criteria and the modified Jadad Scale. The primary outcome was pain control, measured using the visual analog scale 24 h after surgery. Results: Eleven trials met the eligibility criteria and were included in the study. Acupoint stimulation was found more effective than control treatments in terms of pain intensity (standardized mean difference [SMD] -0.94; 95% confidence interval [CI] -1.35 to -0.53), analgesic drug consumption (SMD -1.87; 95% CI -2.98 to -0.75), postoperative nausea (PON; SMD 0.31; 95% CI 0.13 to 0.73), postoperative vomiting (POV; SMD 0.57; 95% CI 0.11 to 2.92), and PON and POV (PONV; SMD 0.29; 95% CI 0.16 to 0.53). The Zusanli (ST36) and Neiguan (PC6) were the most-used acupoints in the included trials (8/11). The reported adverse reaction was only one case of bruising. Discussion: Acupoint stimulation improved pain control in patients undergoing ERAS more than control treatments. The findings provide an evidence-based premise for incorporating acupoint stimulation into ERAS strategies. More rigorous RCTs are needed in the future.

Effect of acupuncture inclusion in the enhanced recovery after surgery protocol on tumor patient gastrointestinal function: a systematic review and meta-analysis of randomized controlled studies

Introduction

Acupuncture has been shown to be effective in restoring gastrointestinal function in tumor patients receiving the enhanced recovery after surgery (ERAS) protocol. The present systematic review and meta-analysis aimed to evaluate the rationality and efficacy of integrating acupuncture in the ERAS strategy to recuperate gastrointestinal function.

Methods

We searched eleven databases for relevant randomized clinical trials (RCTs) of acupuncture for the treatment of gastrointestinal dysfunction in tumor patients treated with the ERAS protocol. The quality of each article was assessed using the Cochrane Collaboration risk of bias criteria and the modified Jadad Scale. As individual symptoms, the primary outcomes were time to postoperative oral food intake, time to first flatus, time to first distension and peristaltic sound recovery time (PSRT). Pain control, adverse events, and acupoint names reported in the included studies were also investigated.

Results

Of the 211 reviewed abstracts, 9 studies (702 patients) met eligibility criteria and were included in the present systematic review and meta‑analysis. Compared to control groups, acupuncture groups showed a significant reduction in time to postoperative oral food intake [standardized mean difference (SMD) = -0.77, 95% confidence interval (CI) -1.18 to -0.35], time to first flatus (SMD=-0.81, 95% CI -1.13 to -0.48), time to first defecation (SMD=-0.91, 95% CI -1.41 to -0.41, PSRT (SMD=-0.92, 95% CI -1.93 to 0.08), and pain intensity (SMD=-0.60, 95% CI -0.83 to -0.37).The Zusanli (ST36) and Shangjuxu (ST37) acupoints were used in eight of the nine included studies. Adverse events related to acupuncture were observed in two studies, and only one case of bruising was reported.

Discussion

The present systematic review and meta‑analysis suggested that acupuncture significantly improves recovery of gastrointestinal function and pain control in tumor patients receiving the ERAS protocol compared to the control group. Moreover, ST36 and ST37 were the most frequently used acupoints. Although the safety of acupuncture was poorly described in the included studies, the available data suggested that acupuncture is a safe treatment with only mild side effects. These findings provide evidence-based recommendations for the inclusion of acupuncture in the ERAS protocol for tumor patients.
