ERAS Implementation & Outcomes
Enhanced Recovery After Surgery (ERAS): Implementation, Outcomes, and Practical Playbook
ERAS protocols consistently shorten length of stay, reduce complications, opioid use, and costs, without increasing readmissions or mortality. Success hinges on multidisciplinary implementation, auditing, and adherence—especially in resource-limited settings where infrastructure and compliance monitoring are frequent barriers [1], [2], [3], [4], [5].
Clinical question
What are the clinical outcomes and implementation strategies for ERAS protocols across surgical populations, and how should teams operationalize and measure ERAS performance?

Key points
High-certainty benefits from trials
A meta-analysis of randomized trials found shorter length of stay with no increase in readmissions, complications, or mortality—supporting ERAS as a safe default perioperative pathway [1].
Geriatric applicability
In older adults undergoing colorectal surgery, ERAS improved outcomes and reduced LOS without compromising safety, reinforcing use in high-risk populations [7].
Cost and opioid reductions
ERAS is associated with lower direct costs and improved financial margins, alongside reduced opioid utilization—a clinical and economic win [6], [2].
Adherence drives results
Programs using audit-and-feedback show higher compliance and shorter LOS; lack of rigorous auditing is a common failure mode [4], [5].
Equity and resource constraints
ERAS can reduce disparities by standardizing high-value care, but limited infrastructure and resources in low-resource settings hinder adherence; tailored pathways and pragmatic metrics are essential [8], [3].
Evidence highlights
−2.5 days on average with ERAS [6]
Length of Stay
No increase vs usual care (RCT meta-analysis) [1]
Readmissions/Mortality
Lower hospital costs and improved margins with ERAS [6], [2]
Costs
Shorter LOS with maintained safety [7]
Geriatric Colorectal
Audit & feedback improves adherence and LOS [5]
Implementation
What ERAS Delivers Clinically and Economically
Evidence across trials, meta-analyses, and real-world implementations shows consistent gains in LOS, complications, opioid exposure, and cost—with stable readmissions and mortality.
1
Length of stay and safety
ERAS reduces LOS versus conventional care, with RCT evidence showing no increase in readmission, complications, or mortality [1]. A recent meta-analysis estimates −2.49 days in LOS and lower costs (SMD −0.36), reinforcing generalizability across procedures [6].
2
Geriatric effectiveness
In geriatric colorectal cohorts, ERAS shortens LOS and improves outcomes without excess adverse events, supporting adoption in older, frailer populations [7].
3
Cost, ICU use, and opioids
ERAS implementations report less ICU utilization, reduced opioid use, and improved hospital margins—translating clinical gains into financial sustainability [2].
4
Global and resource-limited contexts
Adherence is challenged by limited infrastructure, staffing, and perioperative supports; targeted adaptations and compliance tracking are crucial for impact [3], [4].
5
Implementation with audit-and-feedback
An audit-and-feedback (A&F) strategy increased protocol compliance and reduced LOS in colorectal cancer surgery, underscoring the importance of measurement and iterative improvement [5].
Operationalizing ERAS: Core Elements, Measurement, and Equity Considerations
Use this structured checklist to launch or optimize ERAS with emphasis on adherence, data, and sustainability.
Multidisciplinary Governance
Define pathway scope (procedures, inclusion/exclusion).
Form a core team: surgery, anesthesia, nursing, PT/OT, pharmacy, nutrition, case management, IT, finance.
Standardize order sets with auto-default ERAS elements.
Set targets: LOS, complications, readmissions, opioid MME, adherence ≥80% to key elements [4], [5].
Preoperative Elements
Patient education and expectation-setting.
Nutritional screening and optimization; carbohydrate loading if appropriate.
Anemia detection/management; smoking cessation.
Opioid-sparing analgesia planning and PONV prophylaxis bundles.
Intraoperative Elements
Goal-directed fluid therapy; normothermia maintenance.
Multimodal, opioid-sparing analgesia; regional techniques when feasible.
Minimize drains/tubes; antiemetic prophylaxis; early removal plans.
Antimicrobial stewardship with on-time dosing.
Postoperative Elements
Early mobilization protocols; early oral intake as tolerated.
Standardized multimodal analgesia with opioid de-escalation.
Urinary catheter removal targeting POD 0–1; ileus prevention bundle.
Daily goals checklist and discharge criteria pathway.
Measurement & Feedback
Track adherence element-by-element with a dashboard; provide monthly A&F to teams [4], [5].
Core outcomes: LOS, complications, readmissions (7/30-day), mortality, opioid MME, ICU use, costs [1], [6], [2].
Stratify by age, frailty, insurance, language to detect disparities [8], [3].
Common Barriers & Fixes
Barrier: Inadequate auditing/compliance tracking → Fix: real-time dashboards, A&F loops [4], [5].
Barrier: Resource constraints (nutrition, PT, equipment) → Fix: prioritize high-yield elements; phased rollout [3].
Barrier: Clinician variation → Fix: order set hard-stops, standardized education, champions.
Barrier: Patient factors (frailty, literacy) → Fix: tailored education, caregiver engagement, geriatric adjustments [7].
Equity & Low-Resource Adaptation
Implement low-cost, high-impact elements first (education, mobilization, multimodal analgesia) [3].
Use plain-language, multilingual materials; community health workers where possible [8].
Leverage tele-follow-up to reduce readmission risk when access is limited.
Monitor outcome gaps and adjust workflows to close disparities [8], [3].
