Implementation of an Online External Ventricular Drain Training Module-An Educational Initiative to Improve Proficiency of Perioperative Health Care Providers: Results of a Retrospective Study.

BACKGROUND: An external ventricular drain (EVD) training module may improve the knowledge and proficiency of perioperative health care providers (HCPs). METHODS: We examined knowledge gaps, self-reported comfort in managing EVDs, and improvement in self-assessment scores among HCPs from 7 academic medical centers based on an online EVD training module. RESULTS: Of the 326 HCPs who completed the module, 207 (70.6%) reported being uncomfortable managing EVDs. The median pretest scores were 6 (interquartile range=2), and posttest scores were 8 (interquartile range=1), out of a maximum possible score of 9. The most frequent incorrectly answered questions were: (a) maximum allowed hourly cerebrospinal fluid volume drainage (51%), (b) the components of a normal intracranial pressure waveform (41%), and (c) identifying the correct position of the stopcock for accurate measurement of intracranial pressure (41%). The overall gain in scores was 2 (interquartile range=2) and highest among HCPs who had managed 1 to 25 EVDs (2.51, 95% confidence interval: 2.23-2.80), and without self-reported comfort in managing EVDs (2.26, 95% confidence interval: 1.96-2.33, P <0.0001). The majority of participants (312, 95.7%) reported that the training module helped them understand how to manage EVDs, and 276 (84.7%) rated the module 8 or more out of 10 in recommending it to their colleagues. CONCLUSIONS: This online EVD training module was well-received by participants. Overall, improved scores reflect enhanced knowledge among HCPs following completion of the module. The greatest benefit was observed in those reporting less experience and feeling uncomfortable in managing EVDs. The impact on the reduction in EVD-associated adverse events deserves further examination.

An Accessible Clinical Decision Support System to Curtail Anesthetic Greenhouse Gases in a Large Health Network: Implementation Study.

BACKGROUND: Inhaled anesthetics in the operating room are potent greenhouse gases and are a key contributor to carbon emissions from health care facilities. Real-time clinical decision support (CDS) systems lower anesthetic gas waste by prompting anesthesia professionals to reduce fresh gas flow (FGF) when a set threshold is exceeded. However, previous CDS systems have relied on proprietary or highly customized anesthesia information management systems, significantly reducing other institutions' accessibility to the technology and thus limiting overall environmental benefit. OBJECTIVE: In 2018, a CDS system that lowers anesthetic gas waste using methods that can be easily adopted by other institutions was developed at the University of California San Francisco (UCSF). This study aims to facilitate wider uptake of our CDS system and further reduce gas waste by describing the implementation of the FGF CDS toolkit at UCSF and the subsequent implementation at other medical campuses within the University of California Health network. METHODS: We developed a noninterruptive active CDS system to alert anesthesia professionals when FGF rates exceeded 0.7 L per minute for common volatile anesthetics. The implementation process at UCSF was documented and assembled into an informational toolkit to aid in the integration of the CDS system at other health care institutions. Before implementation, presentation-based education initiatives were used to disseminate information regarding the safety of low FGF use and its relationship to environmental sustainability. Our FGF CDS toolkit consisted of 4 main components for implementation: sustainability-focused education of anesthesia professionals, hardware integration of the CDS technology, software build of the CDS system, and data reporting of measured outcomes. RESULTS: The FGF CDS system was successfully deployed at 5 University of California Health network campuses. Four of the institutions are independent from the institution that created the CDS system. The CDS system was deployed at each facility using the FGF CDS toolkit, which describes the main components of the technology and implementation. Each campus made modifications to the CDS tool to best suit their institution, emphasizing the versatility and adoptability of the technology and implementation framework. CONCLUSIONS: It has previously been shown that the FGF CDS system reduces anesthetic gas waste, leading to environmental and fiscal benefits. Here, we demonstrate that the CDS system can be transferred to other medical facilities using our toolkit for implementation, making the technology and associated benefits globally accessible to advance mitigation of health care-related emissions.

International Multicenter Survey of Perioperative Management of External Ventricular Drains: Results of the EVD Aware Study.

INTRODUCTION: The perioperative management of patients with external ventricular drains (EVDs) is not well defined, and adherence to published management guidelines unknown. This study investigates practice, patterns, and variability in the perioperative management of patients with EVDs. METHODS: A 31-question survey was sent to 1830 anesthesiologists from 27 institutions in North America, Europe, and Asia. A perioperative EVD Guideline Adherence Score was calculated for the preoperative, transport and intraoperative periods. Differences in management practices between neuroanesthesiologists and non-neuroanesthesiologists, and factors affecting EVD guideline adherence, were examined using bivariate significance tests and linear regression. RESULTS: Among a sample of 599 anesthesiologists (survey response rate, 32.7%), compared with non-neuroanesthesiologists, neuroanesthesiologists were more likely to include baseline neurological examination (P=0.023), hourly cerebrospinal fluid output (P=0.006) and color (P<0.001), intracranial pressure trends (P<0.001), and EVD clamp trial (P<0.001) data in their routine preanesthetic assessment of patients with EVDs. There was a low prevalence of routine intracranial pressure monitoring during patient transport of patients with EVDs (14.4%). Overall, 25.9% of respondents were aware of EVD guidelines, and 21% reported receiving formal training in EVD management. The EVD Guideline Adherence Score was highest among anesthesiologists who reported being very comfortable in managing patients with EVDs compared with those who reported being uncomfortable (9.93 vs. 6.93, P<0.001). CONCLUSIONS: The EVD Aware study identifies opportunities for improvement in the perioperative management of patients with EVDS, including global awareness, formal EVD training, and dissemination of educational tools.

General Anesthetic Use in Fragile X Spectrum Disorders.

The fragile X premutation is characterized by a repeat expansion mutation (between 55 to 200 CGG repeats) in the fragile X mental retardation 1 (FMR1) gene, which leads to RNA toxicity at the cellular level. This may cause patients with the premutation to be particularly susceptible to environmental toxins, which could manifest clinically as new or worsening ataxia and memory loss. Multiple published case reports have also suggested general anesthetics as a potential toxin leading to negative side effects when used in patients with fragile X-associated disorders. However, at this time, there have been no formal research studies regarding cellular changes or long-term clinical manifestations after general anesthetic use in this population. This review aims to highlight previous case reports regarding sequelae related to general anesthetic use in fragile X-associated disorders. New case reports related to this phenomenon are also included.

Psychotic due to bath salts and methamphetamines: emergency cesarean section under general anesthesia.

The use of "bath salts" or other new psychoactive substances, otherwise known as "legal highs", is increasing. Illicit drug use during pregnancy is not uncommon. Nevertheless, literature reporting bath salts and their effect on pregnancy is scant. Besides, there seems to be no literature about bath salts and conduct of general anesthesia. This case report describes a general anesthetic for the surgical delivery of an infant to a woman under the acute influence of bath salts and methamphetamines.

Perioperative Management of Adult Patients With External Ventricular and Lumbar Drains: Guidelines From the Society for Neuroscience in Anesthesiology and Critical Care.

External ventricular drains and lumbar drains are commonly used to divert cerebrospinal fluid and to measure cerebrospinal fluid pressure. Although commonly encountered in the perioperative setting and critical for the care of neurosurgical patients, there are no guidelines regarding their management in the perioperative period. To address this gap in the literature, The Society for Neuroscience in Anesthesiology & Critical Care tasked an expert group to generate evidence-based guidelines. The document generated targets clinicians involved in perioperative care of patients with indwelling external ventricular and lumbar drains.
