Too loud to hear myself think: deleterious effects of noise in the operating room.

Noise is part of daily life in the operating room, and too often is viewed as a necessary evil. However, much of the noise in operating rooms (ORs) is unnecessary, such as extraneous conversations and music, and could be reduced. At the least, noise is known to increase staff stress and to hamper effective communication; at the worst, it adversely affects patient outcomes. Every member of the OR team should be cognisant of this and work to reduce unnecessary noise.

The movement of syringes and medication during anesthesiology delivery: An observational study in laparoscopic surgeries.

The movements of syringes and medications during an anesthetic case have yet to be systematically documented. We examine how syringes and medication move through the anesthesia work area during a case. We conducted a video-based observational study of 14 laparoscopic surgeries. We defined 'syringe events' as when syringe was picked up and moved. Medications were administered to the patient in only 48 (23.6%) of the 203 medication or syringe events. On average, 14.5 syringe movements occurred in each case. We estimate approximately 4.2 syringe movements for each medication administration. When a medication was administered to the patient (either through the IV pump or the patient port), it was picked up from one of 8 locations in the work area. Our study suggests that the syringe storage locations vary and include irregular locations (e.g., patient bed or provider's pockets). Our study contributes to understanding the complexity in the anesthesia work practices.

The Society of Thoracic Surgeons Adult Cardiac Surgery Database: Intraoperative Echocardiography Reporting.

OBJECTIVES: To identify trends in the reporting of intraoperative transesophageal echocardiographic (TEE) data in the Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database (ACSD) and the Adult Cardiac Anesthesiology (ACA) module by period, practice type, and geographic distribution, and to elucidate ongoing areas for practice improvement. DESIGN: A retrospective study. SETTING: STS ACSD. PARTICIPANTS: Procedures reported in the STS ACSD between July 2017 and December 2021 in participating programs in the United States. INTERVENTIONS: None MEASUREMENTS AND MAIN RESULTS: Intraoperative TEE is reported for 73% of all procedures in ACSD. Although the intraoperative TEE data reporting rate increased from 2017 to 2021 for isolated coronary artery bypass graft surgery, it remained low at 62.2%. The reporting of relevant echocardiographic variables across a wide range of procedures has steadily increased over the study period but also remained low. The reporting in the ACA module is high for most variables and across all anesthesia care models; however, the overall contribution of the ACA module to the ACSD remains low. CONCLUSIONS: This progress report suggests a continued need to raise awareness regarding current practices of reporting intraoperative TEE in the ACSD and the ACA, and highlights opportunities for improving reporting and data abstraction.

Evaluating the Impact of Operative Team Familiarity on Cardiac Surgery Outcomes: A Retrospective Cohort Study of Medicare Beneficiaries.

OBJECTIVE: To associate surgeon-anesthesiologist team familiarity (TF) with cardiac surgery outcomes. BACKGROUND: TF, a measure of repeated team member collaborations, has been associated with improved operative efficiency; however, examination of its relationship to clinical outcomes has been limited. METHODS: This retrospective cohort study included Medicare beneficiaries undergoing coronary artery bypass grafting (CABG), surgical aortic valve replacement (SAVR), or both (CABG+SAVR) between January 1, 2017, and September 30, 2018. TF was defined as the number of shared procedures between the cardiac surgeon and anesthesiologist within 6 months of each operation. Primary outcomes were 30- and 90-day mortality, composite morbidity, and 30-day mortality or composite morbidity, assessed before and after risk adjustment using multivariable logistic regression. RESULTS: The cohort included 113,020 patients (84,397 CABG; 15,939 SAVR; 12,684 CABG+SAVR). Surgeon-anesthesiologist dyads in the highest [31631 patients, TF median (interquartile range)=8 (6, 11)] and lowest [44,307 patients, TF=0 (0, 1)] TF terciles were termed familiar and unfamiliar, respectively. The rates of observed outcomes were lower among familiar versus unfamiliar teams: 30-day mortality (2.8% vs 3.1%, P =0.001), 90-day mortality (4.2% vs 4.5%, P =0.023), composite morbidity (57.4% vs 60.6%, P <0.001), and 30-day mortality or composite morbidity (57.9% vs 61.1%, P <0.001). Familiar teams had lower overall risk-adjusted odds of 30-day mortality or composite morbidity [adjusted odds ratio (aOR) 0.894 (0.868, 0.922), P <0.001], and for SAVR significantly lower 30-day mortality [aOR 0.724 (0.547, 0.959), P =0.024], 90-day mortality [aOR 0.779 (0.620, 0.978), P =0.031], and 30-day mortality or composite morbidity [aOR 0.856 (0.791, 0.927), P <0.001]. CONCLUSIONS: Given its relationship with improved 30-day cardiac surgical outcomes, increasing TF should be considered among strategies to advance patient outcomes.

Anesthesia Workspaces for Safe Medication Practices: Design Guidelines.

BACKGROUND: Studies show that workspace for the anesthesia providers is prone to interruptions and distractions. Anesthesia providers experience difficulties while performing critical medication tasks such as medication preparation and administration due to poor ergonomics and configurations of workspace, equipment clutter, and limited space which ultimately may impact patient safety, length of surgery, and cost of care delivery. Therefore, improving design of anesthesia workspace for supporting safe and efficient medication practices is paramount. OBJECTIVES: The objective of this study was to develop a set of evidence-based design guidelines focusing on design of anesthesia workspace to support safer anesthesia medication tasks in operating rooms (ORs). METHODS: Data collection was based on literature review, observation, and coding of more than 30 prerecorded videos of outpatient surgical procedures to identify challenges experienced by anesthesia providers while performing medication tasks. Guidelines were then reviewed and validated using short survey. RESULTS: Findings are summarized into seven evidence-based design guidelines, including (1) locate critical tasks within a primary field of vision, (2) eliminate travel into and through the anesthesia zone (for other staff), (3) identify and demarcate a distinct anesthesia zone with adequate space for the anesthesia provider, (4) optimize the ability to reposition/reconfigure the anesthesia workspace, (5) minimize clutter from equipment, (6) provide adequate and appropriately positioned surfaces for medication preparation and administration, and (7) optimize task and surface lighting. CONCLUSION: This study finds many areas for improving design of ORs. Improvements of anesthesia work area will call for contribution and cooperation of entire surgical team.

Implementing change in the care of the complex cardiac patient.

PURPOSE OF REVIEW: Development of advanced and minimally invasive surgical procedures is providing treatment opportunities to older and higher risk patients. This has also led to highly specialized physicians and a need for better communication and planning with the patients and within the care team. RECENT FINDINGS: In the field of cardiac surgery, the heart team model has been advocated and implemented as a vehicle to optimize decision making prior to procedure, care during the procedure and in the recovery process. The goal is to provide a treatment path that prioritizes the patient's goals and to anticipate and minimize complications. SUMMARY: In this review, we discuss the concepts of shared decision making (SDM) and implementation science in the context of the complex cardiac patient. We also review the most recent evidence for their use in cardiac surgery. We argue that a team model not only bridges knowledge gaps but provides a multidisciplinary environment for the practice of SDM and implementation of evidence-based practices. Be believe this will provide patients with a better experience as they navigate their care and improve their medical outcomes as well.

Improving safety in the operating room: Medication icon labels increase visibility and discrimination.

Misreading labels, syringes, and ampoules is reported to make up a 54.4% of medication administration errors. The addition of icons to medication labels in an operating room setting could add additional visual cues to the label, allowing for improved discrimination, visibility, and easily processed information that might reduce medication administration errors. A multi-disciplinary team proposed a method of enhancing visual cues and visibility of medication labels applied to vasoactive medication infusions by adding icons to the labels. Participants were 1.12 times more likely to correctly identify medications from farther away (p < 0.001, AOR = 1.12, 95% CI: 1.02, 1.22) with icons. When icons were present, participants were 2.16 times more likely to be more confident in their identifications (p < 0.001, AOR = 2.16, 95%CI: 1.80, 2.57). Carefully designed icons may offer an additional method for identifying medications, and thus reducing medication administration errors.

Role of Value-Added Care by Cardiothoracic Anesthesiology and Impact on Outcomes After Cardiac Surgery.

The medical community is increasingly aware of the need for high-quality and high-value patient care. Anesthesiologists in particular have long demonstrated leadership in the field of quality and safety. Cardiothoracic anesthesiologists can improve the quality of care delivered to cardiac patients both with anesthesia-specific practices and in a team-based approach with other perioperative care providers. Collecting large volumes of multicentered data to study, measure, and improve anesthesia care is one of the many commitments of cardiothoracic anesthesiologists to this cause. This article reviews this and other aspects of the work of cardiothoracic anesthesiologists to improve value-added care to cardiac patients.

Medication errors, critical incidents, adverse drug events, and more: a review examining patient safety-related terminology in anaesthesia.

Literature focused on quantifying or reducing patient harm in anaesthesia uses a variety of labels and definitions to represent patient safety-related events, such as 'medication errors', 'adverse events', and 'critical incidents'. This review extracts and compares definitions of patient safety-related terminology in anaesthesia to examine the scope of this variability and inconsistencies. A structured review was performed in which 36 of the 769 articles reviewed met the inclusion criteria. Similar terms were grouped into six categories by similarities in keyword choice (Adverse Event, Critical Incident, Medication Error, Error, Near Miss, and Harm) and their definitions were broken down into three base components to allow for comparison. Our analysis found that the Medication Error category, which encompasses the greatest number of terms, had widely variant definitions which represent fundamentally different concepts. Definitions of terms within the other categories consistently represented relatively similar concepts, though key variations in wording remain. This inconsistency in terminology can lead to problems with synthesising, interpreting, and overall sensemaking in relation to anaesthesia medication safety. Guidance towards how 'medication errors' should be defined is provided, yet a definition will have little impact on the future of patient safety without organisations and journals taking the lead to promote, publish, and standardise definitions.

Dexmedetomidine, Delirium, and Adverse Outcomes: Analysis of the Society of Thoracic Surgeons Adult Cardiac Surgery Database.

BACKGROUND: We tested the hypothesis that dexmedetomidine was associated with a reduced incidence of postoperative delirium (POD) and adverse outcomes in cardiac surgery patients from The Society of Thoracic Surgeons Adult Cardiac Surgery Database including the Adult Cardiac Anesthesiology subsection. METHODS: We identified 55,905 patients in The Society of Thoracic Surgeons Adult Cardiac Surgery Database who underwent cardiac surgery between July 2014 and December 2018. Using propensity score-weighted regression analysis, we analyzed the effect of intraoperative dexmedetomidine on the primary (POD) and secondary outcomes (highest pain score on day 3 and at discharge, stroke, prolonged ventilation, postoperative intubation/reintubation, additional postoperative hours ventilated, renal failure, atrial fibrillation, and 30-day mortality). In separate propensity score-weighted analyses, we examined the effect of postoperative dexmedetomidine on the highest postoperative pain score at discharge and 30-day mortality. RESULTS: The rate of intraoperative dexmedetomidine use was 25.5% (n = 13,963), and its administration was associated with increased odds for POD (odds ratio, 1.85; 95% confidence interval [CI], 1.60-2.13), a small higher average pain score on day 3 (mean difference, 0.08; 95% CI, 0.02-0.14), increased odds for postoperative intubation/reintubation (odds ratio, 1.29; 95% CI, 1.12-1.48), and a small lower average pain score at discharge (mean difference, -0.31; 95% CI, -0.21 to-0.41). Postoperative dexmedetomidine was associated with a small higher average pain score at discharge (mean difference, 0.27; 95% CI, 0.21-0.34) and higher odds for 30-day mortality (odds ratio, 1.25, 95% CI, 1.07-1.46). CONCLUSIONS: In this registry of cardiac surgical patients dexmedetomidine administration was associated with POD and adverse outcomes.

Observational study of anaesthesia workflow to evaluate physical workspace design and layout.

BACKGROUND: The safety and efficiency of anaesthesia care depend on the design of the physical workspace. However, little is known about the influence that workspace design has on the ability to perform complex operating theatre (OT) work. The aim of this study was to observe the relationship between task switching and physical layout, and then use the data collected to design and assess different anaesthesia workspace layouts. METHODS: In this observational study, six videos of anaesthesia providers were analysed from a single centre in the United States. A task analysis of workflow during the maintenance phase of anaesthesia was performed by categorising tasks. The data supported evaluations of alternative workspace designs. RESULTS: An anaesthesia provider's time was occupied primarily by three tasks: patient (mean: 30.0% of total maintenance duration), electronic medical record (26.6%), and visual display tasks (18.6%). The mean time between task switches was 6.39 s. With the current workspace layout, the anaesthesia provider was centred toward the patient for approximately half of the maintenance duration. Evaluating the alternative layout designs showed how equipment arrangements could improve task switching and increase the provider's focus towards the patient and visual displays. CONCLUSIONS: Our study showed that current operating theatre layouts do not fit work demands. We report a simple method that facilitates a quick layout design assessment and showed that the anaesthesia workspace can be improved to better suit workflow and patient care. Overall, this arrangement could reduce anaesthesia workload while improving task flow efficiency and potentially the safety of care.

The Epiaortic Ultrasound Diagnosis of Iatrogenic Subadventitial Hematoma.

Iatrogenic aortic injury is a rare but potentially lethal complication of cardiac surgery. While sometimes resulting in aortic dissection or intramural hematoma, injury more frequently results in subadventitial hematoma, a more benign pathology. Here, we describe a case where intraoperative transesophageal echocardiography (TEE) identified such a hematoma but was unable to rule out dissection. Epiaortic ultrasound was subsequently performed, which definitively demonstrated the absence of a dissection flap or extraluminal flow. Per our review, this is the first report documenting the successful use of epiaortic imaging to identify subadventitial hematoma in the setting of inconclusive TEE findings.

Clinical Practice Variation and Outcomes for Stanford Type A Aortic Dissection Repair Surgery in Maryland: Report from a Statewide Quality Initiative.

BACKGROUND: Stanford Type A aortic dissection repair surgery is associated with high mortality and clinical practice remains variable among hospitals. Few studies have examined statewide practice variation. METHODS: Patients who had Stanford Type A aortic dissection repair surgery in Maryland between July 1, 2014 and June 30, 2018 were identified using the Maryland Cardiac Surgery Quality Initiative (MCSQI) database. Patient demographics, comorbidities, surgery details, and outcomes were compared between hospitals. We also explored the impact of arterial cannulation site and brain protection technique on outcome. RESULTS: A total of 233 patients were included from eight hospitals during the study period. Seventy-six percent of surgeries were done in two high-volume hospitals (≥10 cases per year), while the remaining 24% were done in low-volume hospitals. Operative mortality was 12.0% and varied between 0 and 25.0% depending on the hospital. Variables that differed significantly between hospitals included patient age, the percentage of patients in shock, left ventricular ejection fraction, creatinine level, arterial cannulation site, brain protection technique, tobacco use, and intraoperative blood transfusion. The percentage of patients who underwent aortic valve repair or replacement procedures differed significantly between hospitals (p < 0.001), although the prevalence of moderate-to-severe aortic insufficiency was not significantly different (p = 0.14). There were no significant differences in clinical outcomes including mortality, renal failure, stroke, or gastrointestinal complications between hospitals or based on arterial cannulation site (all p > 0.05). Patients who had aortic cross-clamping or endovascualr repair had more embolic strokes when compared with patients who had hypothermic circulatory arrest (p = 0.03). CONCLUSION: There remains considerable practice variation in Stanford Type A aortic dissection repair surgery within Maryland including some modifiable factors such as intraoperative blood transfusion, arterial cannulation site, and brain protection technique. Continued efforts are needed within MCSQI and nationally to evaluate and employ the best practices for patients having acute aortic dissection repair surgery.

Gender Bias in Collaborative Medical Decision Making: Emergent Evidence.

This initial, exploratory study on gender bias in collaborative medical decision making examined the degree to which physicians' reliance on a team member's patient care advice differs as a function of the gender of the advice giver. In 2018, 283 anesthesiologists read a brief, online clinical vignette and were randomly assigned to receive treatment advice from 1 of 8 possible sources (physician or nurse, man or woman, experienced or inexperienced). They then indicated their treatment decision, as well as the degree to which they relied upon the advice given.The results revealed 2 patterns consistent with gender bias in participants' advice taking. First, when treatment advice was delivered by an inexperienced physician, participants reported replying significantly more on the advice of a man versus a woman, F(1,61) = 4.24, P = .04. Second, participants' reliance on the advice of the woman physician was a function of her experience, F(1,62) = 6.96, P = .01, whereas reliance on the advice of the man physician was not, F(1,60) = 0.21, P = .65.These findings suggest women physicians, relative to men, may encounter additional hurdles to performing their jobs, especially at early stages in their careers. These hurdles are rooted in psychological biases of others, rather than objective features of cases or treatment settings. Cultural stereotypes may shape physicians' information use and decision-making processes (and hinder collaboration), even in contexts that appear to have little to do with social category membership. The authors recommend institutions adopt policies and practices encouraging equal attention to advice, regardless of the source, to help ensure advice taking is a function of information quality rather than the attributes of the advice giver. Such policies and practices may help surface and implement diverse expert perspectives in collaborative medical decision making, promoting better and more effective patient care.

How do I audit intraoperative blood component utilization in cardiac surgery?

BACKGROUND: Patient blood management programs are tasked with auditing transfusions for appropriateness; however, cardiac surgical programs have high variability in blood utilization. After benchmarking intraoperative blood utilization as higher than expected, we devised effective methods for audits with feedback to the cardiac anesthesiologists that are described in this report. STUDY DESIGN AND METHODS: Red blood cell (RBC), plasma, platelet (PLT), and cryoprecipitate transfusion data were collected from the electronic record system for 2242 patients having cardiac surgery from July 2016 until July 2018. In July 2017, we performed audits with feedback using rank-order bar graphs displayed on the anesthesiology office door for intraoperative blood utilization. Individual providers were compared to their peers for all four major blood components, with the goal of improving practice by reducing variability. RESULTS: After the audits with feedback, the intraoperative mean units/patient decreased for RBCs (from 1.9 to 1.2 units/patient; p = 0.0004), for plasma (from 1.8 to 1.2 units/patient; p = 0.0038), and for PLTs (from 0.7 to 0.4 units/patient; p < 0.0001), but not for cryoprecipitate (from 0.24 to 0.18 units/patient; p = 0.13). Whole hospital (from admit to discharge) utilization decreased significantly for plasma and PLTs, but the changes for RBCs and cryoprecipitate were nonsignificant. CONCLUSION: Despite challenges in abstracting data from the electronic medical record, using such data to create provider-specific audits with feedback can be an effective tool to promote quality improvement. Future plans include audits with feedback for providers who order transfusion outside the operating room.

Partial anomalous pulmonary venous return: Scimitar vein.

Scimitar syndrome is a rare association of congenital cardiopulmonary anomalies characterized by partial anomalous pulmonary venous return, in which an abnormal right pulmonary vein drains into the inferior vena cava. This case exemplifies the role of transesophageal echocardiography in perioperative management and surgical decision-making.
