New-Onset POAF After Craniotomy: Impact on Neurological Outcome, ICU Utilization, and Mortality
Key result
New-onset POAF after neurosurgery is linked to increased complications, longer stays, and higher short-term mortality.
Why the study?
The clinical relevance of perioperative atrial fibrillation in neurosurgical patients remains poorly defined despite their vulnerability to brain injury, inflammation, and perioperative stress.
Is newly detected postoperative atrial fibrillation associated with worse clinical outcomes and resource utilization in neurosurgical patients?
Population
171 neurosurgical patients with pre- and post-procedure ECGs and no prior arrhythmia
Comparison
Newly detected POAF vs remaining in sinus rhythm
Design
Single-center retrospective cohort study

Implication
Highlights need for vigilant care and resource planning in neurosurgical patients with POAF; extends outcome data to this population and is hypothesis-generating for mitigation strategies.
Key Points
- The study aims to determine if newly detected postoperative atrial fibrillation (POAF) worsens outcomes in neurosurgical patients compared to those in sinus rhythm.
- Conducted a single-center retrospective cohort study from October 2020 to April 2025.
- Included patients with both pre- and post-procedure ECGs and no pre-existing arrhythmia.
- Defined POAF as atrial fibrillation detected on any post-procedure ECG.
- Used Welch’s t-test, χ2/Fisher’s exact tests, and odds ratios for analysis.
- Among 171 patients, 79 (46.2%) developed POAF while 92 (53.8%) remained in sinus rhythm.
- Patients with POAF were older and had higher comorbidity burdens.
- POAF was linked to increased postoperative complications and longer ICU stays.
- Lower likelihood of discharge home was observed in POAF patients.
- Higher short-term mortality was noted for those with POAF.

New-onset postoperative atrial fibrillation in neurosurgical patients identifies a high-risk cohort with increased complications, prolonged hospitalization, and higher short-term mortality.
Limitations
- Selected ECG-screened cohort
- Cannot estimate true incidence of POAF in the overall neurosurgical population
