ERAS Protocol Effectiveness in Elderly Abdominal Surgery: A Systematic Review

Fifteen studies involving 2,397 patients were included in this systematic review and meta-analysis by Kexuan Zhu, evaluating Enhanced Recovery After Surgery (ERAS) protocols for elderly patients undergoing major abdominal surgery. The analysis, last updated in May 2026, found ERAS significantly reduced hospital stay and complication rates compared to conventional care. The underlying data supporting the meta-analysis is provided as a supplementary document.

Use Cases

• Comparing length of hospital stay between ERAS and conventional care based on the primary outcome measure
• Analyzing complication and mortality rates in elderly surgical patients based on secondary outcome measures
• Reviewing the composition and reported compliance rates of ERAS protocols from included studies

Strengths

• Analysis is based on 15 studies (6 RCTs and 9 prospective cohort studies) involving 2,397 patients, providing a substantial evidence base.
• The review includes specific quantitative results, such as a mean difference of -3.31 days for length of stay and a relative risk of 0.63 for complications.
• The protocol was registered with PROSPERO (CRD420261381194), indicating a structured methodological approach.

Limitations

• The dataset is a 31.7 KB supplementary document; the underlying raw study data is not provided, limiting direct analysis.
• Column-level documentation for any extracted data is absent; field semantics must be inferred from the manuscript.
• The description notes variability in ERAS implementation and incomplete compliance reporting across the included studies.
