Outcome Measures

Primary Outcomes (7)

  • Rates of General Anesthesia for Cesarean Delivery

    The rates of general anesthesia for cesarean delivery among the institutions in the cohort will be assessed. Descriptive analyses of etiologies of and management of general anesthetics for cesarean delivery will also be performed.

    Up to 5 years

  • Univariate Association Between Facility Type and the Rate of General Anesthesia for Cesarean Delivery

    The association between facility type- non-academic affiliated private vs. academic affiliated private vs. military vs. academic (reference)- with a difference in rates of general anesthesia for cesarean delivery will be assessed.

    Up to 5 years

  • Univariate Association Between SOAP Center of Excellence Designation and the Rate of General Anesthesia for Cesarean Delivery

    The association between SOAP center of excellence designation- yes (reference) vs. no- with a difference in rates of general anesthesia for cesarean delivery will be assessed.

    Up to 5 years

  • Univariate Association Between Maternal Level of Care and the Rate of General Anesthesia for Cesarean Association

    The association between maternal level of care- I vs. II vs. III vs. IV (reference)- with a difference in rates of general anesthesia for cesarean delivery will be assessed.

    Up to 5 years

  • Univariate Association Between Annual Live Births and the Rate of General Anesthesia for Cesarean Delivery

    The association between increased numbers of annual live births (continuous variable) and a difference in rates of general anesthesia for cesarean delivery will be assessed.

    Up to 5 years

  • Univariate Association Between Obstetric Anesthesiologist Coverage and the Rate of General Anesthesia for Cesarean Delivery

    The association between increased rates of labor and delivery floor coverage by obstetric anesthesiologists (continuous variable) and a difference in rates of general anesthesia for cesarean delivery will be assessed.

    Up to 5 years

  • Univariate Association Between Institutional Policies for Labor Epidural Management and the Rate of General Anesthesia for Cesarean Delivery

    The association between the presence of institutional policies for labor epidural management- yes (reference) vs. no- and a difference in rates of general anesthesia for cesarean delivery will be assessed.

    Up to 5 years

Secondary Outcomes (6)

  • Rates of Difficult Intubation Among Women Undergoing General Anesthesia for Cesarean Delivery

    Up to 5 years

  • Univariate Association Between Mallampati Score and the Risk of Difficult Intubation

    Up to 5 years

  • Univariate Association Between Neck Mobility and the Risk of Difficult Intubation

    Up to 5 years

  • Univariate Association Between Neck Circumference and the Risk of Difficult Intubation

    Up to 5 years

  • Univariate Association Between Neck Length and the Risk of Difficult Intubation

    Up to 5 years

  • +1 more secondary outcomes
