Preoperative anxiety and its impact on surgical outcomes: A systematic review and meta-analysis.

ABSTRACT:

Background

Preoperative anxiety is a common phenomenon affecting 60-80% of surgical patients, with potential implications for surgical outcomes. Despite its prevalence, there remains a lack of consensus on its precise effects and optimal management strategies.

Objective

This meta-analysis aimed to synthesize current evidence on the impact of preoperative anxiety on various surgical outcomes, including anesthetic and analgesic requirements, delirium, recovery times, and pain.

Methods

We conducted a comprehensive literature search and meta-analysis of studies examining the relationship between preoperative anxiety and surgical outcomes. Standardized mean differences (SMD), correlation (COR), and odds ratios (OR) with 95% confidence intervals were calculated.
