What is the clinical evidence from this study?

Study design: Cross-Sectional. Population: Non-emergent, non-cardiac surgery (n=127095). Intervention: Non-emergent, non-cardiac surgery. Primary outcome: Incidence of intraoperative hypotension (MAP < 65 mmHg for 15 min or more cumulatively).

What does this research mean for the field?

Intraoperative hypotension occurs in 29% of non-emergent non-cardiac surgical cases in community anesthesia settings and exhibits substantial variation across clinicians after risk adjustment. Novelty: ClaimNovelty.NOVEL_FINDING. Consensus alignment: ConsensusAlignment.NEUTRAL.

Incidence of intraoperative hypotension during non-cardiac surgery in community anesthesia practice: a retrospective observational analysis

Q: What are the key findings of this study?

Among 127,095 non-emergent, non-cardiac cases in community anesthesia settings, 29.0% experienced intraoperative hypotension defined as a mean arterial pressure below 65 mmHg for at least 15 cumulative minutes.

Key result

Intraoperative hypotension affects ~29% of non-emergent, non-cardiac cases in community anesthesia settings.

n=127,095

Why the study?

Intraoperative hypotension is well-described in academic settings and linked to postoperative morbidity and mortality, but its incidence and clinician-level variation in community practice remain uncharacterized.

Design

Cross-sectional descriptive analysis of retrospective data

Authors

WSWael SaasouhWayne State University ACAnna L. ChristensenCambridge Health Alliance FXFei XingHenan University of Technology

Discussion

Member takes

Implication

Frequent in community non-cardiac cases; leaves open whether targeted interventions improve outcomes.

Study Design

Type

Cross-Sectional (n=127,095)

Multicenter

Yes

Structured PICO

Population

127,095 adults undergoing non-emergent, non-cardiac surgery under general, neuraxial, or regional anesthesia in community practice settings.

Outcome

Intraoperative hypotension (binary assessment of whether the case had MAP < 65 mmHg for 15 min or more)surrogate

Intraoperative hypotension is common in community anesthesia practice, occurring in 29% of non-cardiac surgeries, highlighting a highly prevalent and modifiable risk target for quality improvement.

Limitations

Convenience sample from two large anesthesia practices, which may not be nationally representative
Limited to non-emergent non-cardiac surgical procedures
Facilities do not use unified hemodynamic monitoring protocols
Retrospective and descriptive design makes it difficult to determine differences in IOH treatment among clinicians
Unable to adjust the analysis based on combination anesthetics
Risk-adjustment model was limited to only five variables
Lack of outcome data to study the association between IOH and adverse outcomes
No access to detailed comorbidity or hospital data

Saasouh et al. (2023) conducted a cross-sectional in Non-emergent, non-cardiac surgery (n=127,095). Non-emergent, non-cardiac surgery was evaluated on Incidence of intraoperative hypotension (MAP < 65 mmHg for 15 min or more cumulatively). Among 127,095 non-emergent, non-cardiac cases in community anesthesia settings, 29.0% experienced intraoperative hypotension defined as a mean arterial pressure below 65 mmHg for at least 15 cumulative minutes.
