Summary
Near-miss events in Non-Operating Room Anesthesia (NORA) settings, particularly environmental concerns and poor group dynamics, occurred at a 3.22% incidence. Improving NORA safety requires a systems-wide approach to reporting and multidisciplinary collaboration.
Area of Science:
- Anesthesiology
- Patient Safety
- Healthcare Quality Improvement
Background:
- Non-Operating Room Anesthesia (NORA) settings present unique safety challenges due to variable resources and staffing.
- Near-miss events in NORA are often undocumented, hindering safety improvements.
- This study addresses the need for better understanding and reporting of NORA near misses.
Purpose of the Study:
- To determine the incidence and types of near-miss events in Non-Operating Room Anesthesia (NORA) settings.
- To identify key factors contributing to near-miss events in NORA.
- To provide data for improving safety culture and practices in NORA.
Main Methods:
- A prospective cohort study surveyed anesthesiology providers across various in-hospital NORA locations over 42 weeks.
- REDCap surveys were used to collect data on near-miss events, categorized by patient, provider, and environment.
- Data analysis included incidence rate calculation and logistic regression to identify significant contributing factors.
Main Results:
- A near-miss incidence rate of 3.22% was observed, with 90 events reported.
- Environmental concerns (83.3%) and poor group dynamics (34.4%) were the most frequent near-miss categories.
- Factors associated with near misses included older patient age, male sex, higher ASA status, longer/emergent procedures, and resident provider involvement (OR: 2.38, P = .02).
Conclusions:
- Systematic surveying effectively captured previously undocumented near-miss events in NORA.
- Environmental factors and team dynamics are critical areas for NORA safety improvement.
- A systems-wide approach fostering multidisciplinary collaboration and reporting is essential to enhance NORA safety.

General 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...

Endoscopic Studies II: Thoracocentesis
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Stages of General Anesthesia
Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...
Local 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...

Inhalational 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...
