Predictive Validity of Anesthesiologists’ Quality of Clinical Supervision and Nurse Anesthetists’ Work Habits Assessed by Their Associations With Operating Room Times
Authors' conclusion
Specifically, OR times were briefer when anesthesiologists supervised residents more closely, and when CRNAs had better work habits.
Study context
- Population
- Anesthesiologists evaluated by trainees (de Oliveira Filho scale) and nurse anesthetists (CRNAs) evaluated by anesthesiologists, with their OR cases264,060 cases
- Exposure
- Associations of anesthesiologists' supervision quality and CRNAs' work habits with probability of cases taking longer than estimated
- Outcome
- Predictive validity: association between higher supervision quality (work habits) and reduced probability of cases taking longer than estimated
Methodological detailsmixed-effects logistic regression, 8 fiscal years, 40,718 supervision evaluations and 53,722 work habit evaluations; 561 anesthesiologist-years and 605 CRNA-years

Main finding
As reported in the abstract
Anesthesiologists' supervision quality (logit) vs logit probability of case taking longer than estimated: unitless slope (SE 0.0053), P < .00001
−0.0361
CRNAs' work habits (logit) vs logit probability of case taking longer than estimated: slope (SE 0.0054), P < .00001
−0.0238
Observational data: associations, not effects.
