Summary
Healthcare payers are shifting financial risk for anesthesia services to hospitals and physicians. This study explores cost-effective models for utilizing physician anesthesiologists (MDAs) and nurse anesthetists (CRNAs).
Area of Science:
- Health Economics
- Anesthesiology Practice Management
Background:
- Increasing financial risk for anesthesia services due to payer demands for per-diem, global surgery rates, and capitation.
- Need for cost-effective and safe organizational models for anesthesia providers.
Purpose of the Study:
- To examine various organizational models for the cost-effective and safe utilization of physician anesthesiologists (MDAs) and nurse anesthetists (CRNAs).
- To analyze variations in MDA and CRNA practice patterns across different healthcare environments.
Main Methods:
- Description and detailed analysis of four distinct anesthesia practice models.
- Comparison of practitioner utilization ratios (MDA to CRNA) in different states (e.g., California vs. Michigan).
Main Results:
- Significant variations exist in the ratio of MDAs to CRNAs, influenced by managed care environments.
- Physician anesthesiologists (MDAs) incur higher annual costs ($294,000) compared to nurse anesthetists (CRNAs).
Conclusions:
- No single anesthesia practice model is universally optimal.
- Strategic integration of MDAs and CRNAs is crucial for managing costs and ensuring safe anesthesia services amidst evolving payer demands.

01:23Local Anesthetics: Common Agents and Their Applications
Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...
01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

01:24General Anesthesia: Overview
Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

01:24Parenteral Anesthetics: Overview
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.
01:20Inhalational Anesthetics: Overview
Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...
