Changing a clinical pathway to increase spinal anesthesia use for elective hip arthroplasty: a single-centre historical cohort study
Main findingResult — go to the resultUnadjusted difference 8 % 95% CI −7 to 23Authors' conclusion
Implementation of a clinical pathway change to promote spinal anesthesia for total hip arthroplasty may not have been associated with increased use of spinal anesthesia, but utilization rates can vary widely.
Study context
- Population
- Patients undergoing primary unilateral total hip arthroplasty, June 2017 to June 2019
- Participants

- Outcome
- Rate of spinal anesthesia use
Methodological detailssingle-centre, before-after, mixed model multivariable logistic regression with margins analysis

Events by group
After vs Before
unadjusted difference 8 % (95% CI −7 to 23); P = 0.28
Observational data: associations, not effects.
Secondary outcomes
Secondary outcomes (postoperative pain scores, opioid use, complications, unplanned resource use)
- No differences in secondary outcomes
Use of spinal anesthesia, reduced mixed model (average marginal effect of implementation)
- Average marginal effect
- 10.7%
- Upper 95% confidence limit
- 25.7%
Factors associated with receipt of spinal anesthesia
- ASA Physical Status II (vs III), lower BMI and shorter case duration associated with receipt of spinal anesthesia
