This systematic review and Bayesian network meta-analysis evaluated the clinical effects of rule-based electronic surveillance (RB-ES), predictive model-based electronic surveillance (PM-ES), and continuous physiologic monitoring (CPM) in nonintensive care unit settings. The analysis included 28 trials, revealing that none of the surveillance methods significantly reduced in-hospital mortality or ICU transfers compared to standard care, with odds ratios for mortality of 0.91 for RB-ES, 1.22 for PM-ES, and 0.70 for CPM.
Key findings
- Odds ratio for mortality with RB-ES was 0.91 (95% CrI 0.35-2.30) compared to standard care.
- PM-ES showed an odds ratio of 1.22 (95% CrI 0.61-2.31) for mortality.
- CPM had an odds ratio of 0.70 (95% CrI 0.36-1.29) for mortality.
- No clear reduction in cardiac arrest or CPR was observed with expanded surveillance systems (OR 0.94, 95% CI 0.77-1.14).
Why it matters
Understanding the effectiveness of different clinical surveillance technologies is crucial for improving patient outcomes in hospital settings. This study highlights the need for careful consideration of surveillance strategies, as current evidence does not favor one method over another.
