Speech Communication Interference in the Operating Room.

INTRODUCTION: Operating room communication is frequently disrupted, raising safety concerns. We used a Speech Interference Instrument to measure the frequency, impact, and causes of speech communication interference (SCI) events. METHODS: In this prospective study, we observed 40 surgeries, primarily general surgery, to measure the frequency of SCI, defined as "group discourse disrupted according to the participants, the goals, or the physical and situational context of the exchange." We performed supplemental observations, focused on conducting postsurgery interviews with SCI event participants to identify contextual factors. We thematically analyzed notes and interviews. RESULTS: The observed 103 SCI events in 40 surgeries (mean 2.58) mostly involved the attending (50.5%), circulating nurse (44.6%), resident (44.6%), or scrub tech (42.7%). The majority (82.1%) of SCI events occurred during another patient-related task. 17.5% occurred at a critical moment. 27.2% of SCI events were not acknowledged or repeated and the message was lost. Including the supplemental observations, 97.0% of SCI events caused a delay (mean 5 s). Inter-rater reliability, calculated by Gwet's AC1 was 0.87-0.98. Postsurgery interviews confirmed miscommunication and distractions. Attention was most commonly diverted by loud noises (e.g., suction), conversations, or multitasking (e.g., using the electronic health record). Successful strategies included repetition or deferment of the request until competing tasks were complete. CONCLUSIONS: Communication interference may have patient safety implications that arise from conflicts with other case-related tasks, machine noises, and other conversations. Reorganization of workflow, tasks, and communication behaviors could reduce miscommunication and improve surgical safety and efficiency.

Electroencephalography can provide advance warning of technical errors during laparoscopic surgery.

BACKGROUND: Intraoperative adverse events lead to patient injury and death, and are increasing. Early warning systems (EWSs) have been used to detect patient deterioration and save lives. However, few studies have used EWSs to monitor surgical performance and caution about imminent technical errors. Previous (non-surgical) research has investigated neural activity to predict future motor errors using electroencephalography (EEG). The present proof-of-concept cohort study investigates whether EEG could predict technical errors in surgery. METHODS: In a large academic hospital, three surgical fellows performed 12 elective laparoscopic general surgeries. Audiovisual data of the operating room and the surgeon's neural activity were recorded. Technical errors and epochs of good surgical performance were coded into events. Neural activity was observed 40 s prior and 10 s after errors and good events to determine how far in advance errors were detected. A hierarchical regression model was used to account for possible clustering within surgeons. This prospective, proof-of-concept, cohort study was conducted from July to November 2021, with a pilot period from February to March 2020 used to optimize the technique of data capture and included participants who were blinded from study hypotheses. RESULTS: Forty-five technical errors, mainly due to too little force or distance (n = 39), and 27 good surgical events were coded during grasping and dissection. Neural activity representing error monitoring (p = .008) and motor uncertainty (p = .034) was detected 17 s prior to errors, but not prior to good surgical performance. CONCLUSIONS: These results show that distinct neural signatures are predictive of technical error in laparoscopic surgery. If replicated with low false-alarm rates, an EEG-based EWS of technical errors could be used to improve individualized surgical training by flagging imminent unsafe actions-before errors occur and cause patient harm.

The 1990s and the Association for Academic Surgery.

This lecture reviews the progress of the Association for Academic Surgery during the 1990s, a decade of sweeping innovations in technology, communication, and biomedical sciences; a well as a decade of transition in the demographics of surgical trainees; and a decade of new and previously unimagined possibilities for new directions in academic surgical careers.

Technical errors and complications in orthopaedic trauma surgery.

INTRODUCTION: Adverse events and associated morbidity and subsequent costs receive increasing attention in clinical practice and research. As opposed to complications, errors are not described or analysed in literature on fracture surgery. The aim of this study was to provide a description of errors and complications in relation to fracture surgery, as well as the circumstances in which they occur, for example urgency, type of surgeon, and type of fracture. METHODS: All errors and complications were recorded prospectively in our hospital's complication registry, which forms an integral part of the electronic medical patient file. All recorded errors and complications in the complication registry linked to fracture surgery between 1 January, 2000 and 31 December, 2010 were analysed. RESULTS: During the study period 4310 osteosynthesis procedures were performed. In 78 (1.8 %) procedures an error in osteosynthesis was registered. The number of procedures in which an error occurred was significantly lower (OR = 0.53; p = 0.007) when an orthopaedic trauma surgeon was part of the operating team. Of all 3758 patients who were admitted to the surgical ward for osteosynthesis, 745 (19.8 %) had one or more postoperative complications registered. There was no significant difference in the number of postoperative complications after osteosynthesis procedures in which an orthopaedic trauma surgeon was present or absent (16.7 vs. 19.1 %; p = 0.088; OR 0.85). DISCUSSION: In the present study the true error rate after osteosynthesis may have been higher than the rate found. Errors that had no significant consequence may be especially susceptible to underreporting. CONCLUSION: The present study suggests that an osteosynthesis procedure performed by or actively assisted by an orthopaedic trauma surgeon decreases the probability of an error in osteosynthesis. Apart from errors in osteosynthesis, the involvement of an orthopaedic trauma surgeon did not lead to a significant reduction in the number of postoperative complications.

Medical error and disclosure - a view from the U.K.

Whilst the steps for reacting to and communicating following a surgical error should be clear to all, actual practice is punctuated by a range of failures which lead to the harm done by the error being compounded by inadequacies in the disclosure and subsequent processes. This article outlines best practice at the current time within the United Kingdom when responding to a surgical error and it also reports the type of behaviours which result in poor levels of satisfaction from the patients' perspective - often resulting in litigation being invoked.

Analysis of patient safety event report categories at one large academic hospital.

Given the persistent safety incidents in operating rooms (ORs) nationwide (approx. 4,000 preventable harmful surgical errors per year), there is a need to better analyze and understand reported patient safety events. This study describes the results of applying the Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS) supported by the Teamwork Evaluation of Non-Technical Skills (TENTS) instrument to analyze patient safety event reports at one large academic medical center. Results suggest that suboptimal behaviors stemming from poor communication, lack of situation monitoring, and inappropriate task prioritization and execution were implicated in most reported events. Our proposed methodology offers an effective way of programmatically sorting and prioritizing patient safety improvement efforts.

Cognitive Bias and Dissonance in Surgical Practice: A Narrative Review.

A cognitive bias describes "shortcuts" subconsciously applied to new scenarios to simplify decision-making. Unintentional introduction of cognitive bias in surgery may result in surgical diagnostic error that leads to delayed surgical care, unnecessary procedures, intraoperative complications, and delayed recognition of postoperative complications. Data suggest that surgical error secondary to the introduction of cognitive bias results in significant harm. Thus, debiasing is a growing area of research which urges practitioners to deliberately slow decision-making to reduce the effects of cognitive bias.

Pediatric surgical errors: A systematic scoping review.

BACKGROUND: Medical errors were largely concealed prior to the landmark report "To Err Is Human". The purpose of this systematic scoping review was to determine the extent pediatric surgery defines and studies errors, and to explore themes among papers focused on errors in pediatric surgery. METHODS: The methodological framework used to conduct this scoping study has been outlined by Arksey and O'Malley. In January 2020, PubMed, the Cochrane Database of Systematic Reviews, and the Cochrane Central Register of Controlled Trials were searched. Oxford Level of Evidence was assigned to each study; only studies rated Level 3 or higher were included. RESULTS: Of 3,064 initial studies, 12 were included in the final analysis: 4 cohort studies, and 8 outcome/audit studies. This data represented 5,442,000 aggregate patients and 8,893 errors. There were 6 different error definitions and 5 study methods. Common themes amongst the studies included a systems-focused approach, an increase in errors seen with increased complexity, and studies exploring the relationship between error and adverse events. CONCLUSIONS: This study revealed multiple error definitions, multiple error study methods, and common themes described in the pediatric surgical literature. Opportunities exist to improve the safety of surgical care of children by reducing errors. Original Scientific Research Type of Study: Systematic Scoping Review Level of Evidence Rating: 1.

Surgeon's guilt after postoperative complication.

Surgery is an art, surgical dilemmas are not mathematical problems with rigid, straight cut solutions and the human mind/body is not a perfect science. In such a scenario, unexpected, sudden complications can happen during surgery. While better diagnostic and advanced techniques in surgery, have minimised surgical errors to a great extent, with the risk of post-operative death being as low as 3.6% now, still when complications due occur, the surgeon faces a huge backlash not only from the patient relatives, but from his peers, the hospital management, the social and print media. The surgeon also fears violent retribution, not just consumer issues but a threat of arrest and legal battles. All these make a surgeon the "second victim" in the event of a post-operative complication, leading to changes in practice behaviour, emotional turmoil and even serious mental issues like depression and suicide. In this era of instant judgement by a largely unregulated social media, it is urgently required to address this issue and provide appropriate strength/support to the surgical fraternity.

Efficacy of surgical navigation in zygomaticomaxillary complex fractures: randomized controlled trial.

Accurate reduction is of vital importance in the treatment of zygomaticomaxillary complex (ZMC) fractures. Computer-assisted navigation systems (CANS) have been employed in ZMC fractures to improve the accuracy of surgical reduction. However, randomized controlled trials on this subject are rare and the benefits of CANS remain controversial. The aim of this study was to compare reduction errors between navigation-aided and conventional surgical treatment for ZMC fractures. Thirty-eight patients with unilateral type B ZMC fractures were enrolled. Preoperative computed tomography data were imported into ProPlan software for virtual surgical planning. Open reduction and internal fixation was performed with CANS (experimental group) or without CANS (control group). Postoperative computed tomography scans were obtained to examine the difference between surgical planning and the actual postoperative outcome, namely reduction errors. The median translational reduction errors in the X, Y, and Z axes were 0.80 mm, 0.40 mm, and 0.80 mm, respectively, in the experimental group and 0.53 mm, 0.86 mm, and 0.83 mm, respectively, in the control group (P > 0.05). The median rotational reduction errors in pitch, roll, and yaw were 0.92°, 2.47°, and 1.54°, respectively, in the experimental group and 1.45°, 3.68°, and 0.76°, respectively, in the control group (P > 0.05). In conclusion, compared with conventional reduction surgery, navigation-aided surgery showed no significant improvement in reduction accuracy in the treatment of type B ZMC fractures (Chinese Clinical Trial Registry, registration number ChiCTR1800015559).

Use of error management theory to quantify and characterize residents' error recovery strategies.

BACKGROUND: Traditional checklist metrics for surgical performance can miss key intraoperative decisions that impact procedural outcomes. Error-based assessments may help identify important metrics for evaluating operative performance and resident readiness for independent practice. METHODS: This study utilized human factors error analysis and error management theory to investigate a previously collected video database of resident performance during a simulated laparoscopic ventral hernia (LVH) repair on a table-top simulator using standard laparoscopic tools and mesh. Errors were deconstructed and coded using a structured observation tool and video analysis software. Error detection events and error recovery events were categorized for each operative step of the ventral hernia repair. RESULTS: Residents made a total of 314 errors (M = 15.7, SD = 4.96). There were more technical errors (63%) than cognitive errors (37%) and more commission errors (69%) than omission errors (30%). Almost half (47%) of all errors went completely undetected by the residents for the entire LVH repair. Of the errors that residents attempted to recover (n = 136), 86.0% were successfully recovered. Technical errors were four times more likely to be successfully recovered than cognitive errors (p = .020). CONCLUSIONS: Our results revealed specific details regarding residents' error management strategies and provides validity evidence for the use of human factors error frameworks in surgical performance assessments. Practice in simulation-based learning environments may improve resident decision-making and error management opportunities by providing a structured experience where errors are explicitly characterized and used for training and feedback. Error management training may play a major role in equipping residents and junior faculty with the skills required for independent, high-quality operative performance.

Error traps and culture of safety in pediatric surgical oncology.

This article reviews technical issues to improve surgical safety and avoid surgical errors in pediatric surgical oncology, particularly in the three most common extracranial solid tumors: neuroblastoma, hepatoblastoma and Wilms tumor. The use of adjuvant chemotherapy - when indicated - the use of tumor specific classifications, adequate surgical planning, that may include the use of 3D printable models, improved surgical instruments and technology, and following surgical guidelines, would result in avoiding error, increased safety, and therefore in improved surgical outcomes.

Do errors and critical events relate to hernia repair outcomes?

BACKGROUND: The study aimed to validate an error checklist for simulated laparoscopic ventral hernia (LVH) repair procedures. We hypothesize that residents' errors can be assessed with a structured checklist and the results will correlate significantly with procedural outcomes. METHODS: Senior residents' (N = 7) performance on a LVH simulator were video-recorded and analyzed using a human error checklist. Junior residents (N = 38) performed two steps of the same simulated LVH procedure. Performance was evaluated using the error checklist and repair quality scores. RESULTS: There were no significant differences between senior and junior residents' checklist errors (p > 0.1). Junior residents' errors correlated with hernia repair quality (p = 0.05). CONCLUSIONS: The newly developed assessment tool showed significant correlations between performance errors, critical events, and hernia repair quality. These results provide validity evidence for the use of errors in performance assessments. SUMMARY: This study validated an error checklist for simulated laparoscopic ventral hernia (LVH) repair procedures. The checklist was designed based on errors committed by chief surgery residents during LVH repairs. In a separate data collection, junior residents were evaluated using the checklist. Hernia repair quality was also assessed. Errors significantly correlated with hernia repair quality (p = 0.05).

Nontechnical skills in pediatric surgery: Factors influencing operative performance.

Technical competence is an essential aspect of intraoperative performance but is in itself insufficient to ensure an optimal surgical outcome. A list of other skills complement technical ability and these relate, among others, to surgical judgment and intraoperative decision-making processes as well as the role of the operating surgeon as leader of the surgical team. This article outlines the composite set of nontechnical skills (NTS) and the factors which influence surgical performance by virtue of this skill set. A framework has been developed to allow identification, teaching, and assessment of NTS known as Nontechnical Skills for Surgeons (NOTSS), and the relevance and influence of NOTSS during the intraoperative performance of pediatric surgery is presented.

Reducing surgical errors: implementing a three-hinge approach to success.

Surgical errors can have serious consequences including patient deaths, and recent reports suggest that surgical errors continue to occur at unacceptable rates. Studies indicate that causative factors for surgical error include human factors, OR interruptions, staffing issues, and error-reporting trends. A "three-hinge" approach can be used to implement a safety program that emphasizes use of a safe surgery checklist and the Centers for Medicare & Medicaid Services reporting requirements for ambulatory surgery centers. The three hinges are the assignment of a change agent, ideally an RN with a doctorate in nursing practice; team cohesiveness; and continuous quality monitoring.

Errors in neurosurgery.

Medical errors are common and dangerous, estimated to cause over 400,000 deaths per year in the United States alone. The field of neurosurgery is not immune to these errors, and many studies have begun analyzing the frequency and types of errors that neurosurgical patients experience, along with their effects and causes. Fortunately, these data are guiding new innovations to reduce and prevent errors, like checklists, computerized order entry, and an increased appreciation for volume-outcome relationships. This article describes the epidemiology of errors, their classification, methods for identifying and discovering errors, and new strategies for error prevention.

An unusual foreign body in the pelvic cavity after laparotomy.

An unusual case of a glass bottle remaining in the pelvic peritoneal cavity for 6 years after laparotomy is reported, and the prevention of such occurrences is emphasized.

PIP: The case report of a glass specimen bottle which accidentally dropped into the peritoneal cavity at time of laparotomy for a ruptured right tubal pregnancy is presented. It had come to rest on the fundus, open end upward, and during respiration loops of small intestine entered and exited the bottle. When the complaint of pain brought the patient to the authors 6 years later a diagnosis of fibroid uterus was made. It is suggested that all materials used in the abdomen be radio-opaque and that routine postoperative X-rays be taken before the patient leaves the surgical suite.

The role of laparoscopy in the evaluation of candidates for sterilization reversal.

An algorithm that avoids preliminary laparoscopy for sterilization reversal (SR) candidates with previous Pomeroy, loop, Hulka clip, Irving, and single-burn cautery tubal ligation techniques was used. Anastomosis was attempted only when it could be anticipated that the final length of at least one tube would be 3 cm or more. Of 259 SR candidates evaluated according to the algorithm, 235 had SR procedures. Seven of 185 patients (3.8%) who did not undergo laparoscopy were found to have inoperable tubes at laparotomy. Four of these patients had histories of a prior unilateral salpingectomy. The authors conclude that, given their criteria for proceeding with tubal anastomosis, laparoscopy can be avoided in properly selected SR candidates. The results also indicate that patients with a history of unilateral salpingectomy should undergo preliminary laparoscopy.

PIP: An algorithm intended to minimize both the preliminary screening laparoscopy and futile laparotomies was used on 259 consecutive women presenting for sterilization reversal, and the results evaluated. Records were reviewed from 1979 to 1986. First a history, preoperative exam and evaluation including semen analysis, and review of operative records were made. Women with Pomeroy, single-burn cautery, loop, clip or Irving tubal ligations were scheduled for laparotomy for microsurgical reanastomosis. Those with multiple burn tubal ligations or unknown procedures had screening laparoscopy. Of these, women with at least 1 tube 3 cm long underwent laparotomy. Results were considered in terms of successful reanastomosis procedures, since no pregnancy data were available. Of the 8 women who had futile laparotomies, 4 had unilateral salpingectomy and a contralateral Pomeroy ligation, but insufficient tube remained for reversal; 2 others had single-burn cautery, but had insufficient tube length, and the Pomeroy procedures in 2 others left insufficient distal tissue. The benefit of this algorithm was that 71.4% of patients avoided laparoscopy, but the cost was that 7 (3.8%) of these had futile laparotomy. The authors concluded that using 3 cm for the criterion of tube length was optimal, but an unnecessarily high proportion of women had futile operations because of only 1 operable tube, so they recommended that the algorithm be altered to reflect this finding. There could still be inappropriate surgeries due to inaccurate operative records or discrepancies between observations during laparoscopy and actual laparotomy.

Rare events associated with tubal sterilizations: an international experience.

The results from previous analyses of an international data set collected by Family Health International are reviewed in relation to the incidence, severity, risk factors, and outcomes of rare events associated with tubal sterilization. The rare events included for review, by sequence of their relationship to the tubal sterilization procedure are: luteal phase pregnancy, intraoperative complications (uterine perforation, unintended laparotomy required for completion of the laparoscopic procedure, and technical failure in tubal ring sterilization), deaths, early readmission following laparoscopic sterilization, hysterectomy after laparoscopic sterilization, and pregnancy (intrauterine and ectopic) conceived after tubal sterilization. The widespread use of this method of contraception has important public health implications, and awareness of these events will help clinicians minimize such incidences and better deal with them when they arise.

Failures of laparoscopic sterilization by Hulka-Clemens clips.

PIP: The reasons for failure in a series of 544 laparoscopic sterilizations by Hulka-Clemens clips are analyzed. Patients were divided into 2 groups: 1) 327 women sterilized by clips, and 2) 217 women sterilized with clips simultaneous to suction abortion. Most patients were 31-41 years of age. 10 pregnancies were observed in the 4-12 month follow-up, most of which occurred 2-4 months after clip application. None of the pregnancies were ectopic. The higher failure rate in group 2 (7%) compared to group 1 (1.83%) is due to the larger uterine size in the pregnant women. Most failures were attributable to a lack of technical training on the part of operators. In most cases, the clips were applied to a structure other than the tube: round ligament (3 cases), fimbriae (2 cases), utero-ovarian ligament (1 case), twisted spring (3 cases). The cause for failure remains unknown in 1 case. Compared with other sterilization methods (e.g., diathermic coagulation, Yoon ring), the Hulka-Clemens clip procedure has a low rate of method failure. Other studies have noted the following reasons for failure: material, application in already pregnant patients, incomplete nipping of the tubal lumen, application on another structure, and decrease of pressure on the jaws of the clip. Subsequent pregnancies with this method can be avoided by attention to optimal presentation of the uterus during the procedure to facilitate tubal cupping, and adequate supervision when the procedure is done by an inexperienced operator.^ieng
