Surgical adverse events: a systematic review

Hospital and departmental level strategies for managing the impact of adverse events on surgeons

Adverse events have a profound impact on surgeons. This impact extends to physical and mental health, psychological wellbeing, and professional performance. Surgeons are ill prepared for these consequences of adverse events and are under-supported when they inevitably occur. Here we review the data on how adverse events affect surgeons. We explore the efforts made to date to both prepare surgeons before and support them after such events and we make recommendations regarding how this should and could be done better.

Postoperative Complications and Mobilization Following Major Abdominal Surgery With Versus Without Fitness Tracker-based Feedback (EXPELLIARMUS): A Student-led Multicenter Randomized Controlled Clinical Trial of the CHIR-Net SIGMA Study Group

OBJECTIVE

To determine whether daily postoperative step goals and feedback through a fitness tracker (FT) reduce the rate of postoperative complications after surgery.

BACKGROUND

Early and enhanced postoperative mobilization has been advocated to reduce postoperative complications, but it is unknown whether FT alone can reduce morbidity.

METHODS

EXPELLIARMUS was performed at 11 University Hospitals across Germany by the student-led clinical trial network SIGMA. Patients undergoing major abdominal surgery were enrolled, equipped with an FT, and randomly assigned to the experimental (visible screen) or control intervention (blackened screen). The experimental group received daily step goals and feedback through the FT. The primary end point was postoperative morbidity within 30 days using the Comprehensive Complication Index (CCI). All trial visits were performed by medical students in the hospital with the opportunity to consult a surgeon-facilitator who also obtained informed consent. After discharge, medical students performed the 30-day postoperative visit through telephone and electronic questionnaires.

RESULTS

A total of 347 patients were enrolled. Baseline characteristics were comparable between the 2 groups. The mean age of patients was 58 years, and 71% underwent surgery for malignant disease, with the most frequent indications being pancreatic, colorectal, and hepatobiliary malignancies. Roughly one-third of patients underwent laparoscopic surgery. No imputation for the primary end point was necessary as data completeness was 100%. There was no significant difference in the CCI between the 2 groups in the intention-to-treat analysis (mean±SD CCI experimental group: 23±24 vs. control: 22±22; 95% CI: -6.1, 3.7; P=0.628). All secondary outcomes, including quality of recovery, 6-minute walking test, length of hospital stay, and step count until postoperative day 7 were comparable between the 2 groups.

CONCLUSIONS

Daily step goals combined with FT-based feedback had no effect on postoperative morbidity. The EXPELLIARMUS shows that medical students can successfully conduct randomized controlled trials in surgery.

Mixed methods evaluation of a specialty-specific system to promote physician engagement in safety and quality reporting in a large academic health system

BACKGROUND

Incident reporting systems (IRS) can improve care quality and patient safety, yet their impact is limited by clinician engagement. Our objective was to assess barriers to reporting in a hospital-wide IRS and use data to inform ongoing improvement of a specialty-specific IRS embedded in the electronic health record targeting anaesthesiologists.

METHODS

This quality improvement (QI) evaluation used mixed methods, including qualitative interviews, faculty surveys and user data from the specialty-specific IRS. We conducted 24 semi-structured interviews from January to May 2023 in a large academic health system in Northern California. Participants included adult and paediatric anaesthesiologists, operating room nurses, surgeons and QI operators, recruited through convenience and snowball sampling. We identified key themes and factors influencing engagement, which were classified using the Systems Engineering Initiative for Patient Safety framework. We surveyed hospital anaesthesiologists in January and May 2023, and characterised the quantity and type of reports submitted to the new system.

RESULTS

Participants shared organisation and technology-related barriers to engagement in traditional system-wide IRSs, many of which the specialty-specific IRS addressed-specifically those related to technological access to the system. Barriers related to building psychological safety for those who report remain. Survey results showed that most barriers to reporting improved following the specialty-specific IRS launch, but limited time remained an ongoing barrier (25 respondents out of 44, 56.8%). A total of 964 reports with quality/safety concerns were submitted over the first 8 months of implementation; 47-76 unique anaesthesiologists engaged per month. The top safety quality categories of concern were equipment and technology (25.9%), clinical complications (25.3%) and communication and scheduling (19.9%).

CONCLUSIONS

These findings suggest that a specialty-specific IRS can facilitate increased physician engagement in quality and safety reporting and complement existing system-wide IRSs.

Improving quality and patient safety in surgical care through standardisation and harmonisation of perioperative care (SAFEST project): A research protocol for a mixed methods study

INTRODUCTION

Adverse events in health care affect 8% to 12% of patients admitted to hospitals in the European Union (EU), with surgical adverse events being the most common types reported.

AIM

SAFEST project aims to enhance perioperative care quality and patient safety by establishing and implementing widely supported evidence-based perioperative patient safety practices to reduce surgical adverse events.

METHODS

We will conduct a mixed-methods hybrid type III implementation study supporting the development and adoption of evidence-based practices through a Quality Improvement Learning Collaborative (QILC) in co-creation with stakeholders. The project will be conducted in 10 hospitals and related healthcare facilities of 5 European countries. We will assess the level of adherence to the standardised practices, as well as surgical complications incidence, patient-reported outcomes, contextual factors influencing the implementation of the patient safety practices, and sustainability. The project will consist of six components: 1) Development of patient safety standardised practices in perioperative care; 2) Guided self-evaluation of the standardised practices; 3) Identification of priorities and actions plans; 4) Implementation of a QILC strategy; 5) Evaluation of the strategy effectiveness; 6) Patient empowerment for patient safety. Sustainability of the project will be ensured by systematic assessment of sustainability factors and business plans. Towards the end of the project, a call for participation will be launched to allow other hospitals to conduct the self-evaluation of the standardized practices.

DISCUSSION

The SAFEST project will promote patient safety standardized practices in the continuum of care for adult patients undergoing surgery. This project will result in a broad implementation of evidence-based practices for perioperative care, spanning from the care provided before hospital admission to post-operative recovery at home or outpatient facilities. Different implementation challenges will be faced in the application of the evidence-based practices, which will be mitigated by developing context-specific implementation strategies. Results will be disseminated in peer-reviewed publications and will be available in an online platform.

Detection of Adverse Events With the Austrian Inpatient Quality Indicators

OBJECTIVES

Indicators based on routine data are considered a readily available and cost-effective method for assessing health care quality and safety. The Austrian Inpatient Quality Indicators (A-IQI) have been introduced in all Austrian public hospitals as a mandatory quality measurement. The purpose of this study was to assess the value of conspicuous A-IQI in predicting the presence of adverse events (AEs).

METHODS

We conducted an exploratory study comparing all indicator-positive patient cases contributing to 18 conspicuous A-IQI indicators to randomly selected indicator-negative control cases regarding the prevalence and severity of AEs. Structured medical record review using the Institute for Healthcare Improvement Global Trigger Tool was used as the gold standard.

RESULTS

In 421 chart reviews, we identified 158 AEs. 70.9% (n = 112) of the AEs were found in cases with a positive indicator. The relative risk of an AE occurring was 3.47 (95% confidence interval: 2.30, 5.24) in indicator-positive cases compared to indicator-negatives. The proportion of severe events (National Coordination Council for Medication Error Reporting and Prevention Index categories H and I) was 54.5% (n = 61) in indicator-positive cases and only 15.3% (n = 7) in indicator-negative cases. Overall sensitivity of the A-IQI was 68.2%, specificity 69.4%, positive predictive value 36.0%, and negative predictive value 89.6%.

CONCLUSIONS

Our study shows that significantly more AEs and more severe AEs were found in cases with positive A-IQI than in indicator-negative control cases. However, studies with larger numbers of cases and with larger numbers of conspicuous indicators are needed for the validation of the entire A-IQI indicator set.

Optimizing Teamwork in the Operating Room: A Scoping Review of Actionable Teamwork Strategies

Suboptimal teamwork in the operating room (OR) is a contributing factor in a significant proportion of preventable complications for surgical patients. Specifying behaviour is fundamental to closing evidence-practice gaps in healthcare. Current teamwork interventions, however, have yet to be synthesized in this way. This scoping review aimed to identify actionable strategies for use during surgery by mapping the existing literature according to the Action, Actor, Context, Target, Time (AACTT) framework. The databases MEDLINE (Medical Literature Analysis and Retrieval System Online), Embase, Cumulated Index to Nursing and Allied Health Literature (CINAHL), Education Resources Information Center (ERIC), Cochrane, Scopus, and PsycINFO were searched from inception to April 5, 2022. Screening and data extraction were conducted in duplicate by pairs of independent reviewers. The search identified 9,289 references after the removal of duplicates. Across 249 studies deemed eligible for inclusion, eight types of teamwork interventions could be mapped according to the AACTT framework: bundle/checklists, protocols, audit and feedback, clinical practice guidelines, environmental change, cognitive aid, education, and other), yet many were ambiguous regarding the actors and actions involved. The 101 included protocol interventions appeared to be among the most actionable for the OR based on the clear specification of ACCTT elements, and their effectiveness should be evaluated and compared in future work.

European society for trauma and emergency surgery member-identified research priorities in emergency surgery: a roadmap for future clinical research opportunities

BACKGROUND

European Society for Trauma and Emergency Surgery (ESTES) is the European community of clinicians providing care to the injured and critically ill surgical patient. ESTES has several interlinked missions - (1) the promotion of optimal emergency surgical care through networked advocacy, (2) promulgation of relevant clinical cognitive and technical skills, and (3) the advancement of scientific inquiry that closes knowledge gaps, iteratively improves upon surgical and perioperative practice, and guides decision-making rooted in scientific evidence. Faced with multitudinous opportunities for clinical research, ESTES undertook an exercise to determine member priorities for surgical research in the short-to-medium term; these research priorities were presented to a panel of experts to inform a 'road map' narrative review which anchored these research priorities in the contemporary surgical literature.

METHODS

Individual ESTES members in active emergency surgery practice were polled as a representative sample of end-users and were asked to rank potential areas of future research according to their personal perceptions of priority. Using the modified eDelphi method, an invited panel of ESTES-associated experts in academic emergency surgery then crafted a narrative review highlighting potential research priorities for the Society.

RESULTS

Seventy-two responding ESTES members from 23 countries provided feedback to guide the modified eDelphi expert consensus narrative review. Experts then crafted evidence-based mini-reviews highlighting knowledge gaps and areas of interest for future clinical research in emergency surgery: timing of surgery, inter-hospital transfer, diagnostic imaging in emergency surgery, the role of minimally-invasive surgical techniques and Enhanced Recovery After Surgery (ERAS) protocols, patient-reported outcome measures, risk-stratification methods, disparities in access to care, geriatric outcomes, data registry and snapshot audit evaluations, emerging technologies interrogation, and the delivery and benchmarking of emergency surgical training.

CONCLUSIONS

This manuscript presents the priorities for future clinical research in academic emergency surgery as determined by a sample of the membership of ESTES. While the precise basis for prioritization was not evident, it may be anchored in disease prevalence, controversy around aspects of current patient care, or indeed the identification of a knowledge gap. These expert-crafted evidence-based mini-reviews provide useful insights that may guide the direction of future academic emergency surgery research efforts.

Assessing the utility of natural language processing for detecting postoperative complications from free medical text

BACKGROUND

Postoperative complication rates are often assessed through administrative data, although this method has proven to be imprecise. Recently, new developments in natural language processing have shown promise in detecting specific phenotypes from free medical text. Using the clinical challenge of extracting four specific and frequently undercoded postoperative complications (pneumonia, urinary tract infection, sepsis, and septic shock), it was hypothesized that natural language processing would capture postoperative complications on a par with human-level curation from electronic health record free medical text.

METHODS

Electronic health record data were extracted for surgical cases (across 11 surgical sub-specialties) from 18 hospitals in the Capital and Zealand regions of Denmark that were performed between May 2016 and November 2021. The data set was split into training/validation/test sets (30.0%/48.0%/22.0%). Model performance was compared with administrative data and manual extraction of the test data set.

RESULTS

Data were obtained for 17 486 surgical cases. Natural language processing achieved a receiver operating characteristic area under the curve of 0.989 for urinary tract infection, 0.993 for pneumonia, 0.992 for sepsis, and 0.998 for septic shock, whereas administrative data achieved a receiver operating characteristic area under the curve of 0.595 for urinary tract infection, 0.624 for pneumonia, 0.571 for sepsis, and 0.625 for septic shock.

CONCLUSION

The natural language processing approach was able to capture complications with acceptable performance, which was superior to administrative data. In addition, the model performance approached that of manual curation and thereby offers a potential pathway for complete real-time coverage of postoperative complications across surgical procedures based on natural language processing assessment of electronic health record free medical text.

Implementation of a comprehensive clinical risk management system in a university hospital

BACKGROUND

Adverse events during hospital treatment are common and can lead to serious harm. This study reports the implementation of a comprehensive clinical risk management system in a university hospital and assesses the impact of clinical risk management on patient harms.

METHODS

The clinical risk management system was rolled out over a period of eight years and consisted of a training of interdisciplinary risk management teams, external and internal risk audits, and the implementation of a critical incident reporting system (CIRS). The risks identified during the audits were analyzed according to the type, severity, and implementation of preventive measures. Other key figures of the risk management system were obtained from the annual risk reports. The number of liability cases was used as primary outcome measurement.

RESULTS

Of the 1,104 risks identified during the risk audits, 56.2% were related to organization, 21.3% to documentation, 15.3% to treatment, and 7.2% to patient information and consent. The highest proportion of serious risks was found in the category organization (22.7%), the lowest in the category documentation (13.6%). Critical incident reporting identified between 241 and 370 critical incidents per year, for which in 79.5% to 83% preventive measures were implemented within twelve months. The frequency of incident reports per department correlated with the number of active risk managers and risk team meetings. Compared with the years prior to the introduction of the clinical risk management system, an average annual reduction of harms by 60.1% (95% CI: 57.1; 63.1) was observed two years after the implementation was completed. On average, the rate of harms dropped by 5% per year for each 10% increase in roll-out of the clinical risk management system (incidence rate ratio: 0.95; 95% CI: 0.93; 0.97) .

CONCLUSION

The results of this project demonstrate the effectiveness of clinical risk management in detecting treatment-related risks and in reducing harm to patients.

Surgical Safety Does Not Happen By Accident: Learning From Perioperative Near Miss Case Studies

Adverse surgical events cause negative patient health outcomes and harm that can often overshadow the safe and effective patient care provided daily by nurses as members of interprofessional healthcare teams. Near misses occur far more frequently than adverse events and are less visible to nurse leaders because patient harm is avoided due to chance, prevention, or mitigation. However, near misses have comparable root causes to adverse events and exhibit the same underlying patterns of failure. Reviewing near misses provides nurses with learning opportunities to identify patient care weaknesses and build appropriate solutions to enhance care. As the operating room is one of the most complex work settings in healthcare, identifying potential weaknesses or sources for errors is vital to reduce healthcare-associated risks for patients and staff. The purpose of this manuscript is to educate, inform, and stimulate critical thinking by discussing perioperative near miss case studies and the underlying factors that lead to errors. Our authors discuss 15 near miss case studies occurring across the perioperative patient experience of care and discuss barriers to near miss reporting. Nurse leaders can use our case studies to stimulate discussion among perioperative and perianesthesia nurses in their hospitals to inform comprehensive risk reduction programs.

Analysis of adverse events in general surgery. Multicenter study

INTRODUCTION

Knowledge of adverse events (AE) in acute care hospitals is a particularly relevant aspect of patient safety. Its incidence ranges from 3% to 17%, and surgery is related to the occurrence of 46%-65% of all AE.

MATERIAL AND METHODS

An observational, descriptive, retrospective, multicenter study was conducted with the participation of 31 Spanish acute-care hospitals to determine and analyze AE in general surgery services.

RESULTS

The prevalence of AE was 31.53%. The most frequent types of AE were infectious (35%). Higher ASA grades, greater complexity and urgent-type admission are factors associated with the presence of AE. The majority of patients (58.42%) were attributed a category F event (temporary harm to the patient requiring initial or prolonged hospitalization); 14.69% of AE were considered severe, while 34.22% of AE were considered preventable.

CONCLUSIONS

The prevalence of AE in General and GI Surgery (GGIS) patients is high. Most AE were infectious, and the most frequent AE was surgical site infection. Higher ASA grades, greater complexity and urgent-type admission are factors associated with the presence of AE. Most detected AE resulted in mild or moderate harm to the patients. About one-third of AE were preventable.

Perioperative Environment Safety Culture: A Scoping Review Addressing Safety Culture, Climate, Enacting Behaviors, and Enabling Factors

While there is an increasing interest in patient safety and in transforming safety culture in the perioperative environment, it is not clear what methods are being used to understand, assess, and influence safety culture and climate. This article seeks to uncover what instruments and measures are used to assess safety culture and investigates how these measures are applied in baseline assessments and interventions in the perioperative environment to enhance/support safety culture. Study investigators are encouraged to collect and analyze data about engaging in behaviors that prevent, respond to, or resolve safety issues, and related factors that support understanding their effects.

Peer Support and Second Victim Programs for Anesthesia Professionals Involved in Stressful or Traumatic Clinical Events

Modern anesthetic care is very safe, but stressful and traumatic clinical events may occur. When they occur, anesthesia professionals are vulnerable to second victim experiences, resulting in significant and long-lasting psychological and emotional consequences if not addressed. Peer support can help anesthesia professionals cope with the negative effects of second victim experiences.

Definitions of serious injury in long-term residential care: a systematic review protocol

Background: Evidence indicates that the reporting of serious injury in long-term residential care has increased substantially over the past decade. However, what constitutes a serious injury in residential care is poorly and inconsistently defined. This may result in incidences being unnecessarily reported as a serious injury. It is therefore, crucial to develop a consistent definition of serious injury to reduce reporting burden and to facilitate comparison between different residential care settings and across jurisdictions. This protocol describes the methods for a systematic review of existing definitions from the literature to inform the development of a consistent definition of serious injury in long-term residential care. Methods: A wide range of published peer-reviewed and grey literature will be sought for this review, including guidance and policy documents. Searches will be conducted of databases including MEDLINE, CINAHL, SocINDEX, Academic Search Ultimate, and Westlaw International. Grey literature database searches will include Trip and Social Care Online. Country specific searches of government and health and social care websites will be conducted. Quality appraisal will be facilitated using the Quality Assessment for Diverse Studies (QuADS) tool and Tyndall's checklist. The level of confidence in the findings will be assessed using the GRADE CERQual approach. A customised data extraction form will be used to extract data to reduce the risk of bias. Conceptual content analysis of data will facilitate identification of definitions of serious injury and their frequency within texts. Conclusions: The findings will inform the development of a consistent definition of serious injury in long-term residential care that will reduce reporting burden, facilitate the accuracy of data collected and allow for comparison across jurisdictions. A more universal and consistent definition will enable regulators, policy makers, service providers and researchers to develop policy and practical interventions to prevent the occurrence of serious injury in long-term residential care.

Improving surgical safety checklist utilisation at 23 public health facilities in Ethiopia: a collaborative quality improvement project

BACKGROUND

In 2009, the WHO introduced the surgical safety checklist (SSC) as one of the interventions for improving patient safety. The systematic use of structured checklists during surgery has been shown to reduce perioperative morbidity and mortality. However, SSC utilisation has been challenging in low-income and middle-income countries, including Ethiopia. Jhpiego Ethiopia implemented a quality improvement project (QIP) aimed to increase SSC utilisation.

METHODOLOGY

A model for improvement was used to design and implement a collaborative QIP to improve SSC utilisation at 23 public health facilities (13 primary health care facilities, 4 general hospitals and 6 tertiary hospitals) in Ethiopia from October 2020 to September 2021. SSC utilisation was defined as when a patient chart had SSC attached and each part of the checklist was completed. Training of surgical staff on safe surgery packages, monthly clinical mentorship and cluster-based learning platforms were implemented during the study period. We analysed bimonthly chart audit reports from each facility to assess the proportion of surgeries where the SSC was used. Shewhart charts were used to conduct a time-series analysis. Additionally, the Z-test for two sample proportions was used to determine if there is a statistically significant change from the baseline measure with a p<0.05.

RESULT

In the postintervention period, the overall SSC utilisation improved by 39.9 absolute percentage points to 90.3% (p<0.0001) compared with the baseline value of 50.4% early in 2020. A time-series analysis using Shewhart charts showed a shift in the mean performance and signals of special cause variation. The largest improvement was observed in primary health care facilities in which the SSC utilisation improved from 50.8% to 97.9% (p<0.0001).

CONCLUSION

This study demonstrates that onsite clinical capacity building, mentorship and collaborative cluster-based learning platforms can improve SSC utilisation across all levels of facilities performing surgery.

Development of individual competencies and team performance in interprofessional ward rounds: results of a study with multimodal observations at the Heidelberg Interprofessional Training Ward

Introduction

Interprofessional training wards (IPTW) aim to improve undergraduates' interprofessional collaborative practice of care. Little is known about the effects of the different team tasks on IPTW as measured by external assessment. In Heidelberg, Germany, four nursing and four medical undergraduates (= one cohort) care for up to six patients undergoing general surgery during a four-week placement. They learn both professionally and interprofessionally, working largely on their own responsibility under the supervision of the medical and nursing learning facilitators. Interprofessional ward rounds are a central component of developing individual competencies and team performance. The aim of this study was to evaluate individual competencies and team performance shown in ward rounds.

Methods

Observations took place in four cohorts of four nursing and four medical undergraduates each. Undergraduates in one cohort were divided into two teams, which rotated in morning and afternoon shifts. Team 1 was on morning shift during the first (t0) and third (t1) weeks of the IPTW placement, and Team 2 was on morning shift during the second (t0) and fourth (t1) weeks. Within each team, a tandem of one nursing and one medical undergraduate cared for a patient room with three patients. Ward round observations took place with each team and tandem at t0 and t1 using the IP-VITA instrument for individual competencies (16 items) and team performance (11 items). Four hypotheses were formulated for statistical testing with linear mixed models and correlations.

Results

A total of 16 nursing and medical undergraduates each were included. There were significant changes in mean values between t0 and t1 in individual competencies (Hypothesis 1). They were statistically significant for all three sum scores: "Roles and Responsibilities", Patient-Centeredness", and "Leadership". In terms of team performance (Hypothesis 2), there was a statistically significant change in mean values in the sum score "Roles and Responsibilities" and positive trends in the sum scores "Patient-Centeredness" and "Decision-Making/Collaborative Clinical Reasoning". Analysis of differences in the development of individual competencies in the groups of nursing and medical undergraduates (Hypothesis 3) showed more significant differences in the mean values of the two groups in t0 than in t1. There were significant correlations between individual competencies and team performance at both t0 and t1 (Hypothesis 4).

Discussion

The study has limitations due to the small sample and some sources of bias related to the external assessment by means of observation. Nevertheless, this study offers insights into interprofessional tasks on the IPTW from an external assessment. Results from quantitative and qualitative analysis of learners self-assessment are confirmed in terms of roles and responsibilities and patient-centeredness. It has been observed that medical undergraduates acquired and applied skills in collaborative clinic reasoning and decision-making, whereas nursing undergraduates acquired leadership skills. Within the study sample, only a small group of tandems remained constant over time. In team performance, the group of constant tandems tended to perform better than the group of random tandems. The aim of IPTW should be to prepare healthcare team members for the challenge of changing teams. Therefore, implications for IPTW implementation could be to develop learning support approaches that allow medical and nursing undergraduates to bring interprofessional competencies to team performance, independent of the tandem partner or team.

Analyzing interprofessional teamwork in the operating room: An exploratory observational study using conventional and alternative approaches

Intraoperative teamwork is vital for patient safety. Conventional tools for studying intraoperative teamwork typically rely on behaviorally anchored rating scales applied at the individual or team level, while others capture narrative information across several units of analysis. This prospective observational study characterizes teamwork using two conventional tools (Operating Theatre Team Non-Technical Skills Assessment Tool [NOTECHS]; Team Emergency Assessment Measure [TEAM]), and one alternative approach (modified-Systems Engineering Initiative for Patient Safety [SEIPS] model). We aimed to explore the advantages and disadvantages of each for providing feedback to improve teamwork practice. Fifty consecutive surgical cases at a Canadian academic hospital were recorded with the OR Black Box®, analyzed by trained raters, and summarized descriptively. Teamwork performance was consistently high within and across cases rated with NOTECHS and TEAMS. For cases analyzed with the modified-SEIPS tool, both optimal and suboptimal teamwork behaviors were identified, and team resilience was frequently observed. NOTECHS and TEAM provided summative assessments and overall pattern descriptions, while SEIPS facilitated a deeper understanding of teamwork processes. As healthcare organizations continue to prioritize teamwork improvement, SEIPS may provide valuable insights regarding teamwork behavior and the broader context influencing performance. This may ultimately enhance the development and effectiveness of multi-level teamwork interventions.

Gaze behavior is related to objective technical skills assessment during virtual reality simulator-based surgical training: a proof of concept

PURPOSE

Simulation-based training allows surgical skills to be learned safely. Most virtual reality-based surgical simulators address technical skills without considering non-technical skills, such as gaze use. In this study, we investigated surgeons' visual behavior during virtual reality-based surgical training where visual guidance is provided. Our hypothesis was that the gaze distribution in the environment is correlated with the simulator's technical skills assessment.

METHODS

We recorded 25 surgical training sessions on an arthroscopic simulator. Trainees were equipped with a head-mounted eye-tracking device. A U-net was trained on two sessions to segment three simulator-specific areas of interest (AoI) and the background, to quantify gaze distribution. We tested whether the percentage of gazes in those areas was correlated with the simulator's scores.

RESULTS

The neural network was able to segment all AoI with a mean Intersection over Union superior to 94% for each area. The gaze percentage in the AoI differed among trainees. Despite several sources of data loss, we found significant correlations between gaze position and the simulator scores. For instance, trainees obtained better procedural scores when their gaze focused on the virtual assistance (Spearman correlation test, N = 7, r = 0.800, p = 0.031).

CONCLUSION

Our findings suggest that visual behavior should be quantified for assessing surgical expertise in simulation-based training environments, especially when visual guidance is provided. Ultimately visual behavior could be used to quantitatively assess surgeons' learning curve and expertise while training on VR simulators, in a way that complements existing metrics.

Does the Type of Surgical Headwear Worn in the OR Matter? A Review of Evidence and Opinions

Proper surgical attire is essential in decreasing surgical site infections; however, the effectiveness of the different types of headwear is a controversial topic. We conducted a narrative review based on studies identified through a focused literature search to summarize and critically assess evidence and opinions on the most appropriate type of headwear for OR personnel. We included 48 articles: 17 original research studies and 31 non-peer-reviewed articles of various types. Research published before 2014 mostly supports the complete coverage of all hair, which aligns with the 2015 AORN guidelines. However, more recent literature rebuts these guidelines and emphasizes the importance of clean headwear. Although earlier studies (published before 2017) lacked scientific rigor, later studies (published after 2017) have other various limitations, including missing data on compliance, surgery-related techniques, and surgical attire other than headwear. The findings from this review highlight the importance of solid evidence-based guidelines and expert collaboration.

Prediction of postoperative patient deterioration and unanticipated intensive care unit admission using perioperative factors

BACKGROUND AND OBJECTIVES

Currently, no evidence-based criteria exist for decision making in the post anesthesia care unit (PACU). This could be valuable for the allocation of postoperative patients to the appropriate level of care and beneficial for patient outcomes such as unanticipated intensive care unit (ICU) admissions. The aim is to assess whether the inclusion of intra- and postoperative factors improves the prediction of postoperative patient deterioration and unanticipated ICU admissions.

METHODS

A retrospective observational cohort study was performed between January 2013 and December 2017 in a tertiary Dutch hospital. All patients undergoing surgery in the study period were selected. Cardiothoracic surgeries, obstetric surgeries, catheterization lab procedures, electroconvulsive therapy, day care procedures, intravenous line interventions and patients under the age of 18 years were excluded. The primary outcome was unanticipated ICU admission.

RESULTS

An unanticipated ICU admission complicated the recovery of 223 (0.9%) patients. These patients had higher hospital mortality rates (13.9% versus 0.2%, p<0.001). Multivariable analysis resulted in predictors of unanticipated ICU admissions consisting of age, body mass index, general anesthesia in combination with epidural anesthesia, preoperative score, diabetes, administration of vasopressors, erythrocytes, duration of surgery and post anesthesia care unit stay, and vital parameters such as heart rate and oxygen saturation. The receiver operating characteristic curve of this model resulted in an area under the curve of 0.86 (95% CI 0.83-0.88).

CONCLUSIONS

The prediction of unanticipated ICU admissions from electronic medical record data improved when the intra- and early postoperative factors were combined with preoperative patient factors. This emphasizes the need for clinical decision support tools in post anesthesia care units with regard to postoperative patient allocation.

Nontechnical Skills for Surgeons as a Framework to Evaluate Cardiopulmonary Bypass Management Skills of Resident Trainees

BACKGROUND

Nontechnical skills are critical in cardiac surgery but currently there is no formal paradigm to teach these in residency training. We investigated the use of the Nontechnical skills for surgeons (NOTSS) system as a framework to assess and teach nontechnical skills related to cardiopulmonary bypass (CPB) management.

METHODS

Single-center retrospective analysis of Integrated and Independent pathway thoracic surgery residents who participated in dedicated nontechnical skills evaluation and training. Two CPB management simulation scenarios were utilized. All residents received a lecture on CPB fundamentals and then individually participated in the first simulation ("Pre-NOTSS"). Immediately following this, nontechnical skills were rated by self-assessment and by a NOTSS trainer. All residents then underwent group NOTSS training followed by the second individual simulation ("Post-NOTSS"). Nontechnical skills were rated as before. NOTSS categories assessed included Situation Awareness, Decision Making, Communication and Teamwork, and Leadership.

RESULTS

Nine residents were divided into 2 groups: Junior (n = 4, PGY1-4) and Senior (n = 5, PGY5-8). Pre-NOTSS resident self-ratings were higher for Senior than Junior in the categories of Decision Making, Communication and Teamwork, and Leadership while trainer ratings were similar between the groups. Post-NOTSS, resident self-ratings were higher for Senior than Junior in Situation Awareness and Decision Making while trainer scores were higher for both groups in Communication and Teamwork and Leadership.

CONCLUSIONS

The NOTSS framework in conjunction with simulation scenarios provides a practical framework to evaluate and teach nontechnical skills related to CPB management. NOTSS training can lead to improvements in both subjective and objective ratings of nontechnical skills for all PGY levels.

Neurological complications in patients undergoing general surgery: A literature review

Surgical procedures are extremely burdensome for patients, as in addition to complications directly related to the intervention, they expose the patient to further complications resulting from the disturbance of key functions of homeostasis in the body's systems, particularly the circulatory, respiratory, and nervous systems. Furthermore, they may contribute to the exacerbation of symptoms of underlying chronic diseases. This paper focuses on the most common possible neurological complications that may occur after surgical procedures and includes topics such as stroke, chronic pain, neuropathy, and delirium. The risk factors for neurological deficits, their known or possible etiology, the most characteristic symptoms, and potential preventive actions are discussed. The paper analyzes articles from the PubMed, ResearchGate, and Scopus databases. A surge0on's knowledge of possible complications that may occur in the perioperative period enables early recognition and effective reduction of their negative impact on the patient's functioning and quality of life after surgery, contributing to better overall treatment outcomes.

Validation of the first computerized indicator for orthopaedic surgical site infections in France: ISO-ORTHO

BACKGROUND

The French national authority for health (HAS) develops in-hospital indicators for improving quality of care, safety and patient outcome. Since 2017, it has developed a measurement of surgical site infections (SSI) after total hip or knee arthroplasty (TH/KA) by using a computerized indicator, called ISO-ORTHO, based on a hospital discharge database (HDD) algorithm. The aim of the study was to assess the performance of this new indicator .

METHODS

The ISO-ORTHO performance was estimated via its positive predictive value (PPV) among adult patients having undergone a TH/KA between January 1st and September 30th 2018, based on the orthopaedic procedure codes. Patients at very high risk of SSI and/or with SSI not related to the in-hospital care were excluded. SSI were detected from the date of admission up to 90 days after the TH/KA using the ISO-ORTHO algorithm, based on 15 combinations of ICD-10 and procedure codes. Its PPV was estimated by a chart review in volunteer healthcare organisations (HCO).

RESULTS

Over the study period, 777 HCO including 143,227 TH/KA stays were selected, providing 1,279 SSI according to the ISO-ORTHO indicator. The 90-day SSI rate was 0.89 per 100 TH/KA stays (0.98% for THA and 0.80% for TKA). Among the 448 HCO with at least 1 SSI, 250 HCO participated in reviewing 725 SSI charts; 665 were confirmed, giving a PPV of 90.3% [88.2-92.5%], 89.9% [87.1-92.8%] in THA and 90.9% [87.7-94.2%] in TKA.

CONCLUSIONS

The PPV of ISO-ORTHO over 90% confirms its validity for any use according to the HAS method. ISO-ORTHO and detailed information were provided in 2020 to HCO and used for quality assessment and in-hospital risk management.

The need for non-technical skills education in orthopedic surgery

BACKGROUND

The issue of surgical safety has increased significantly over the last few decades. Several studies have established that it is linked to non-technical performance, rather than clinical competencies. Non-technical skills can be blended with technical training in the surgical profession to improve surgeons' abilities and enhance patient care and procedural skills. The main goal of this study was to determine orthopedic surgeons' requirements of non-technical skills, and to identify the most pressing issues.

METHODS

We conducted a self-administered online questionnaire survey in this cross-sectional study. The questionnaire was piloted, validated, pretested, and clearly stated the study's purpose. After the pilot, minor wording and questions were clarified before starting the data collection. Orthopedic surgeons from the Middle East and Northern Africa were invited. The questionnaire was based on a five-point Likert scale, the data were analyzed categorically, and variables were summarized as descriptive statistics.

RESULTS

Of the 1713 orthopedic surgeons invited, 60% completed the survey (1033 out of 1713). The majority demonstrated a high likelihood of participating in such activities in the future (80.5%). More than half (53%) of them preferred non-technical skills courses to be part of major orthopedic conferences, rather than independent courses. Most (65%) chose them to be face-to-face. Although 97.2% agreed on the importance of these courses, only 27% had attended similar courses in the last three years. Patient safety, infection prevention and control, and communication skills were ranked at the top as topics to be addressed. Moreover, participants indicated they would most likely attend courses on infection prevention and control, patient safety and teamwork, and team management.

CONCLUSION

The results highlight the need for non-technical skills training in the region and the general preferences regarding modality and setting. These findings support the high demand from orthopedic surgeons' perspective to develop an educational program on non-technical skills.

How Many People Experience Unsafe Medical Care in Thailand, and How Much Does It Cost under Universal Coverage Scheme?

Adverse events and medical harm comprise major health concerns for people all over the world, including Thailand. The prevalence and burden of medical harm must always be monitored, and a voluntary database should not be used to represent national value. The purpose of this study is to estimate the national prevalence and economic impact of medical harm in Thailand using routine administrative data from the inpatient department electronic claim database under the Universal Coverage scheme from 2016 to 2020. Our findings show that there are approximately 400,000 visits with potentially unsafe medical care per year (or 7% of all inpatient visits under the Universal Coverage scheme). The annual cost of medical harm is estimated to be approximately USD 278 million (approximately THB 9.6 billion), with an average of 3.5 million bed-days per year. This evidence can be used to raise safety awareness and support medical harm prevention policies. Future work should focus on improving medical harm surveillance using better data quality and more comprehensive data on medical harm.

Implementation of an Innovative Technology Called the OR Black Box: A Feasibility Study

Introduction. The operating room (OR) Black Box is an innovative technology that captures and compiles extensive real-time data from the OR, allowing identification and analysis of factors that influence intraoperative procedures and performances - ultimately improving patient safety. Implementation of this kind of technology is still an emerging research area and prone to face challenges. Methods. Observational study running from May 2017 to May 2021 conducted at Copenhagen University Hospital - Rigshospitalet, Denmark, involving 152 OR staff and 306 patients. Feasibility of the OR Black Box was assessed in accordance with Bowen's framework with 8 focus areas. Results. The OR Black Box had a high level of acceptability among stakeholders with 100% participation from management, 93% from OR staff, and 98% from patients. The implementation process improved over time, and an average of 80% of the surgeries conducted were captured. The practical aspects such as numerous formal and informal meetings, ethical and legal approval, recruitment of patients were acceptable, albeit time-consuming. The OR Black Box was adopted without any changes in scheduled surgery program, but capturing hours were adjusted to match the surgery program and relocation of OR staff declining to provide consent was possible. Conclusions. Implementation of the OR Black Box was feasible yet challenging. Management, nearly all staff, and patients embraced the initiative; however, ongoing evaluation, information meetings, and commitment from stakeholders are required and crucial to sustain momentum, continue implementation and expansion. Ideas from this study can be useful in the implementation of similar initiatives.

Extension of patient safety initiatives to perioperative care

PURPOSE OF REVIEW

Patient safety has significantly improved during the intraoperative period thanks to the anesthesiologists, surgeons, and nurses. Nowadays, it is within the perioperative period where most of the preventable harm happened to the surgical patient. We aim to highlight the main issues and efforts to improve perioperative patient safety focusing and the relation to intraoperative safety strategies.

RECENT FINDINGS

There is ongoing research on perioperative safety strategies aiming to initiate multidisciplinary interventions on early stages of the perioperative period as well as an increasing focus on preventing harm from postoperative complications.

SUMMARY

Any patient safety strategy to be implemented needs to be framed beyond the operating room and include in the intervention the whole perioperative period.

Intraoperative Code Blue: Improving Teamwork and Code Response Through Interprofessional, In Situ Simulation

INTRODUCTION

An intraoperative cardiac arrest requires perioperative teams to be equipped with the technical skills, nontechnical skills, and confidence to provide the best resuscitative measures for the patient. In situ simulation (simulation conducted in health professionals' work environment, such as a patient care unit, and not in an off-site location) has the potential to improve team performance. The research team assessed the effects of in situ simulation on code response, teamwork, communication, and comfort in intraoperative resuscitations.

METHODS

This study included seven interprofessional teams consisting of RNs, anesthesiologists, surgical technologists, and patient care technicians working in the operating room of a community hospital in New Jersey. The hour-long interdisciplinary simulation training sessions consisted of a code blue scenario run twice; both times video recorded, retrospectively reviewed, and compared to each other. Technical skills were measured by "time-to-tasks"; nontechnical skills were assessed using the Team Emergency Assessment Measure (TEAM) instrument. Self-reported comfort in skills was collected before the simulation program and after completion of the training.

RESULTS

A total of 21 perioperative nurses, 7 anesthesiologists, 7 surgical technologists, and 4 patient care technicians participated from January to April 2021. There was a significant (p < 0.05) decrease in time to compressions (by 14 seconds, 53.5% improvement) and in time to defibrillation (by 49 seconds) between the two simulations. Significant improvements were noted in confidence levels of certain CPR-related technical skills. There were statistically significant improvements in TEAM scores in the two teams that performed lowest in the pre-debrief simulation (p < 0.05).

CONCLUSION

In the operative setting, where time and space for training are limited, in situ simulation training was associated with improvement in technical skills of individuals and teams, with significantly improved teamwork in teams that required the most training. The long-term effects of such training and its effects on patient outcomes require additional research.

Analyzing and Discussing Human Factors Affecting Surgical Patient Safety Using Innovative Technology: Creating a Safer Operating Culture

INTRODUCTION

Surgical errors often occur because of human factor-related issues. A medical data recorder (MDR) may be used to analyze human factors in the operating room. The aims of this study were to assess intraoperative safety threats and resilience support events by using an MDR and to identify frequently discussed safety and quality improvement issues during structured postoperative multidisciplinary debriefings using the MDR outcome report.

METHODS

In a cross-sectional study, 35 standard laparoscopic procedures were performed and recorded using the MDR. Outcome data were analyzed using the automated Systems Engineering Initiative for Patient Safety model. The video-assisted MDR outcome report reflects on safety threat and resilience support events (categories: person, tasks, tools and technology, psychical and external environment, and organization). Surgeries were debriefed by the entire team using this report. Qualitative data analysis was used to evaluate the debriefings.

RESULTS

A mean (SD) of 52.5 (15.0) relevant events were identified per surgery. Both resilience support and safety threat events were most often related to the interaction between persons (272 of 360 versus 279 of 400). During the debriefings, communication failures (also category person) were the main topic of discussion.

CONCLUSIONS

Patient safety threats identified by the MDR and discussed by the operating room team were most frequently related to communication, teamwork, and situational awareness. To create an even safer operating culture, educational and quality improvement initiatives should aim at training the entire operating team, as it contributes to a shared mental model of relevant safety issues.

Multi-center validation of machine learning model for preoperative prediction of postoperative mortality

Accurate prediction of postoperative mortality is important for not only successful postoperative patient care but also for information-based shared decision-making with patients and efficient allocation of medical resources. This study aimed to create a machine-learning prediction model for 30-day mortality after a non-cardiac surgery that adapts to the manageable amount of clinical information as input features and is validated against multi-centered rather than single-centered data. Data were collected from 454,404 patients over 18 years of age who underwent non-cardiac surgeries from four independent institutions. We performed a retrospective analysis of the retrieved data. Only 12–18 clinical variables were used for model training. Logistic regression, random forest classifier, extreme gradient boosting (XGBoost), and deep neural network methods were applied to compare the prediction performances. To reduce overfitting and create a robust model, bootstrapping and grid search with tenfold cross-validation were performed. The XGBoost method in Seoul National University Hospital (SNUH) data delivers the best performance in terms of the area under receiver operating characteristic curve (AUROC) (0.9376) and the area under the precision-recall curve (0.1593). The predictive performance was the best when the SNUH model was validated with Ewha Womans University Medical Center data (AUROC, 0.941). Preoperative albumin, prothrombin time, and age were the most important features in the model for each hospital. It is possible to create a robust artificial intelligence prediction model applicable to multiple institutions through a light predictive model using only minimal preoperative information that can be automatically extracted from each hospital.

Association between surgeon age and postoperative complications/mortality: a systematic review and meta-analysis of cohort studies

The surgical workforce, like the rest of the population, is ageing. This has raised concerns about the association between the age of the surgeon and their surgical outcomes. We performed a systematic review and meta-analysis of cohort studies on postoperative mortality and major morbidity according to the surgeons' age. The search was performed on February 2021 using the Embase, Medline and CENTRAL databases. Postoperative mortality and major morbidity were evaluated as clinical outcomes. We categorized the surgeons' age into young-, middle-, and old-aged surgeons. We compared the differences in clinical outcomes for younger and older surgeons compared to middle-aged surgeons. Subgroup analyses were performed for major and minor surgery. Ten retrospective cohort studies on 29 various surgeries with 1,666,108 patients were considered. The mortality in patients undergoing surgery by old-aged surgeons was 1.14 (1.02-1.28, p = 0.02) (I² = 80%) compared to those by middle-aged surgeon. No significant differences were observed according to the surgeon's age in the major morbidity and subgroup analyses. This meta-analysis indicated that surgeries performed by old-aged surgeons had a higher risk of postoperative mortality than those by middle-aged surgeons. Thus, it necessitates the introduction of a multidisciplinary approach to evaluate the performance of senior surgeons.

Compliance with the World Health Organization's surgical safety checklist and related postoperative outcomes: a nationwide survey among 172 health facilities in Ethiopia

Background

Ministry of Health (MOH) of Ethiopia adopted World Health Organization’s evidence-proven surgical safety checklist (SSC) to reduce the occurrence of surgical complications, i.e., death, disability and prolong hospitalization. MOH commissioned this evaluation to learn about SSC completeness and compliance, and its effect on magnitude of surgical complications.

Methods

Health institution-based cross-sectional study with retrospective surgical chart audit was used to evaluate SSC utilization in 172 public and private health facilities in Ethiopia, December 2020–May 2021. A total of 1720 major emergency and elective surgeries in 172 (140 public and 32 private) facilities were recruited for chart review by an experienced team of surgical clinicians. A pre-tested tool was used to abstract data from patient charts and national database. Analyzed descriptive, univariable and bivariable data using Stata version-15 statistical software.

Results

In 172 public and private health facilities across Ethiopia, 1603 of 1720 (93.2%) patient charts were audited; representations of public and private facilities were 81.4% (n = 140) and 18.6% (n = 32), respectively. Of surgeries that utilized SSC (67.6%, 1083 of 1603), the proportion of SSC that were filled completely and correctly were 60.8% (659 of 1083). Surgeries compliant to SSC guide achieved a statistically significant reduction in perioperative mortality (P = 0.002) and anesthesia adverse events (P = 0.005), but not in Surgical Site Infection (P = 0.086). Non-compliant surgeries neither utilized SSC nor completed the SSC correctly, 58.9% (944 of 1603).

Conclusions

Surgeries that adhered to the SSC achieved a statistically significant reduction in perioperative complications, including mortality. Disappointingly, a significant number of surgeries (58.9%) failed to adhere to SSC, a missed opportunity for reducing complications.

Effect of the Surgical Safety Checklist on the incidence of adverse events: contributions from a national study

OBJECTIVE

the study evaluated the effect of using the safe surgery checklist (CL) on the incidence of adverse events (AE).

METHODS

cross-sectional and retrospective research with 851 patients undergoing surgical procedures in 2012 (n=428) and 2015 (n=423), representing the periods before and after CL implantation. The AE incidences for each year were estimated and compared. The association between the occurrence of AE and the presence of CL in the medical record was analyzed.

RESULTS

a reduction in the point estimate of AE was observed from 13.6% (before using the CL) to 11.8% (with the use of the CL). The difference between the proportions of AE in the periods before and after the use of CL was not significant (p=0.213). The occurrence of AE showed association with the following characteristics: anesthetic risk of the patient, length of stay, surgery time and classification of the procedure according to the potential for contamination. Considering the proportion of deaths, there was a significant reduction in deaths (p=0.007) in patients whose CL was used when compared to those without the use of the instrument. There was no significant association between the presence of CL and the occurrence of AE. It was concluded that the presence of CL in the medical record did not guarantee an expected reduction in the incidence of AE.

CONCLUSION

however, it is believed that the use of the instrument integrated with other patient safety strategies can improve the safety/quality of surgical care in the long term.

Continuous monitoring of surgical bimanual expertise using deep neural networks in virtual reality simulation

In procedural-based medicine, the technical ability can be a critical determinant of patient outcomes. Psychomotor performance occurs in real-time, hence a continuous assessment is necessary to provide action-oriented feedback and error avoidance guidance. We outline a deep learning application, the Intelligent Continuous Expertise Monitoring System (ICEMS), to assess surgical bimanual performance at 0.2-s intervals. A long-short term memory network was built using neurosurgeon and student performance in 156 virtually simulated tumor resection tasks. Algorithm predictive ability was tested separately on 144 procedures by scoring the performance of neurosurgical trainees who are at different training stages. The ICEMS successfully differentiated between neurosurgeons, senior trainees, junior trainees, and students. Trainee average performance score correlated with the year of training in neurosurgery. Furthermore, coaching and risk assessment for critical metrics were demonstrated. This work presents a comprehensive technical skill monitoring system with predictive validation throughout surgical residency training, with the ability to detect errors.

Surgery Is in Itself a Risk Factor for the Patient

(1) Background: Adverse events (AE) affect about 1 in 10 hospitalised patients, and almost half are related to surgical care. The aim of this study is to determine the prevalence of AE in operated and non-operated patients in surgical departments in order to determine whether surgical treatment is a risk factor for AE. (2) Methods: A cross-sectional design that included 3123 patients of 34 public hospitals in the Community of Madrid determining the prevalence of AEs in operated and non-operated patients in surgical departments. (3) Results: The prevalence of AE in non-operated patients was 8.7% and in those operated was 15.8%. The frequency of AE was higher in emergency surgery (20.6% vs. 12.4%). The 48.3% of AEs led to an increase in hospital stay, and surgery was involved in 92.4% of cases. The most frequent AEs were related to hospital-acquired infection (42.63%), followed by those related to a procedure (37.72%). In the multivariate analysis, being operated on represented 2.3 times the risk of developing an AE. (4) Conclusions: Surgical sites are particularly vulnerable to AE. Surgical intervention alone is a risk factor for AE, and we must continue to work to improve the safety of both patient care and the working environment of surgical professionals.

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.

The Effect of Major and Minor Complications After Lung Surgery on Length of Stay and Readmission

The effect of post-operative adverse events (AEs) on patient outcomes such as length of stay (LOS) and readmissions to hospital is not completely understood. This study examined the severity of AEs from a high-volume thoracic surgery center and its effect on the patient postoperative LOS and readmissions to hospital. This study includes patients who underwent an elective lung resection between September 2018 and January 2020. The AEs were grouped as no AEs, 1 or more minor AEs, and 1 or more major AEs. The effects of the AEs on patient LOS and readmissions were examined using a survival analysis and logistic regression, respectively, while adjusting for the other demographic or clinical variables. Among 488 patients who underwent lung surgery, (Wedge resection [n = 100], Segmentectomy [n = 51], Lobectomy [n = 310], Bilobectomy [n = 10], or Pneumonectomy [n = 17]) for either primary (n = 440) or secondary (n = 48) lung cancers, 179 (36.7%) patients had no AEs, 264 (54.1%) patients had 1 or more minor AEs, and 45 (9.2%) patients had 1 or more major AEs. Overall, the median of LOS was 3 days which varied significantly between AE groups; 2, 4, and 8 days among the no, minor, and major AE groups, respectively. In addition, type of surgery, renal disease (urinary tract infection [UTI], urinary retention, or acute kidney injury), and ASA (American Society of Anesthesiology) score were significant predictors of LOS. Finally, 58 (11.9%) patients were readmitted. Readmission was significantly associated with AE group (P = 0.016). No other variable could significantly predict patient readmission. Overall, postoperative AEs significantly affect the postoperative LOS and readmission rates.

Analysis of Surgical Mortalities Using the Fishbone Model for Quality Improvement in Surgical Disciplines

BACKGROUND

The healthcare industry is complex and prone to the occurrence of preventable patient safety incidents. Most serious patient safety events in surgery are preventable.

AIM

This study was conducted to determine the rate of occurrence of preventable mortalities and to use the fishbone model to establish the main contributing factors.

METHODS

We reviewed the records of patients who died following admission to the surgical wards. Data regarding their demography, diagnosis, acuity, comorbidities, categorization of death and contributing factors were extracted from the Research Electronic Data Capture (REDCap) database. Factors which contributed to preventable and potentially preventable mortalities were collated. The fishbone model was used for root cause analysis. The study received prior ethical clearance (M190122).

RESULTS

Records of 859 mortalities were found, of which 65.7% (564/859) were males. The median age of the patients who died was 49 years (IQR: 33-64 years). The median length of hospital stay before death was three days (IQR: 1-11 days). Twenty-four percent (24.1%) of the deaths were from gastrointestinal (GIT) emergencies, 18.4% followed head injury and 17.0% from GIT cancers. Overall, 5.4% of the mortalities were preventable, and 41.1% were considered potentially preventable. The error of judgment and training issues accounted for 46% of mortalities.

CONCLUSION

Most surgical mortalities involve males, and around 46% are either potentially preventable or preventable. The majority of the mortality were associated with GIT emergencies, head injury and advanced malignancies of the GIT. The leading contributing factors to preventable and potentially preventable mortalities were the error of judgment, inadequate training and shortage of resources.

Increased adherence to perioperative safety guidelines associated with improved patient safety outcomes: a stepped-wedge, cluster-randomised multicentre trial

BACKGROUND

National Dutch guidelines have been introduced to improve suboptimal perioperative care. A multifaceted implementation programme (IMPlementatie Richtlijnen Operatieve VEiligheid [IMPROVE]) has been developed to support hospitals in applying these guidelines. This study evaluated the effectiveness of IMPROVE on guideline adherence and the association between guideline adherence and patient safety.

METHODS

Nine hospitals participated in this unblinded, superiority, stepped-wedge, cluster RCT in patients with major noncardiac surgery (mortality risk ≥1%). IMPROVE consisted of educational activities, audit and feedback, reminders, organisational, team-directed, and patient-mediated activities. The primary outcome of the study was guideline adherence measured by nine patient safety indicators on the process (stop moments from the composite STOP bundle, and timely administration of antibiotics) and on the structure of perioperative care. Secondary safety outcomes included in-hospital complications, postoperative wound infections, mortality, length of hospital stay, and unplanned care.

RESULTS

Data were analysed for 1934 patients. The IMPROVE programme improved one stop moment: 'discharge from recovery room' (+16%; 95% confidence interval [CI], 9-23%). This stop moment was related to decreased mortality (-3%; 95% CI, -4% to -1%), fewer complications (-8%; 95% CI, -13% to -3%), and fewer unscheduled transfers to the ICU (-6%; 95% CI, -9% to -3%). IMPROVE negatively affected one other stop moment - 'discharge from the hospital' - possibly because of the limited resources of hospitals to improve all stop moments together.

CONCLUSIONS

Mixed implementation effects of IMPROVE were found. We found some positive associations between guideline adherence and patient safety (i.e. mortality, complications, and unscheduled transfers to the ICU) except for the timely administration of antibiotics.

How Did Orthopaedic Surgeons Perform in the 2018 Centers for Medicaid & Medicare Services Merit-based Incentive Payment System?

BACKGROUND

The Merit-based Incentive Payment System (MIPS) is the latest value-based payment program implemented by the Centers for Medicare & Medicaid Services. As performance-based bonuses and penalties continue to rise in magnitude, it is essential to evaluate this program's ability to achieve its core objectives of quality improvement, cost reduction, and competition around clinically meaningful outcomes.

QUESTIONS/PURPOSES

We asked the following: (1) How do orthopaedic surgeons differ on the MIPS compared with surgeons in other specialties, both in terms of the MIPS scores and bonuses that derive from them? (2) What features of surgeons and practices are associated with receiving penalties based on the MIPS? (3) What features of surgeons and practices are associated with receiving a perfect score of 100 based on the MIPS?

METHODS

Scores from the 2018 MIPS reporting period were linked to physician demographic and practice-based information using the Medicare Part B Provider Utilization and Payment File, the National Plan and Provider Enumeration System Data (NPPES), and National Physician Compare Database. For all orthopaedic surgeons identified within the Physician Compare Database, there were 15,210 MIPS scores identified, representing a 72% (15,210 of 21,124) participation rate in the 2018 MIPS. Those participating in the MIPS receive a final score (0 to 100, with 100 being a perfect score) based on a weighted calculation of performance metrics across four domains: quality, promoting interoperability, improvement activities, and costs. In 2018, orthopaedic surgeons had an overall mean ± SD score of 87 ± 21. From these scores, payment adjustments are determined in the following manner: scores less than 15 received a maximum penalty adjustment of -5% ("penalty"), scores equal to 15 did not receive an adjustment ("neutral"), scores between 15 and 70 received a positive adjustment ("positive"), and scores above 70 (maximum 100) received both a positive adjustment and an additional exceptional performance adjustment with a maximum adjustment of +5% ("bonus"). Adjustments among orthopaedic surgeons were compared across various demographic and practice characteristics. Both the mean MIPS score and the resulting payment adjustments were compared with a group of surgeons in other subspecialties. Finally, multivariable logistic regression models were generated to identify which variables were associated with increased odds of receiving a penalty as well as a perfect score of 100.

RESULTS

Compared with surgeons in other specialties, orthopaedic surgeons' mean MIPS score was 4.8 (95% CI 4.3 to 5.2; p < 0.001) points lower. From this difference, a lower proportion of orthopaedic surgeons received bonuses (-5.0% [95% CI -5.6 to -4.3]; p < 0.001), and a greater proportion received penalties (+0.5% [95% CI 0.2 to 0.8]; p < 0.001) and positive adjustments (+4.6% [95% CI 6.1 to 10.7]; p < 0.001) compared with surgeons in other specialties. After controlling for potentially confounding variables such as gender, years in practice, and practice setting, small (1 to 49 members) group size (adjusted odds ratio 22.2 [95% CI 8.17 to 60.3]; p < 0.001) and higher Hierarchical Condition Category (HCC) scores (aOR 2.32 [95% CI 1.35 to 4.01]; p = 0.002) were associated with increased odds of a penalty. Also, after controlling for potential confounding, we found that reporting through an alternative payment model (aOR 28.7 [95% CI 24.0 to 34.3]; p < 0.001) was associated with increased odds of a perfect score, whereas small practice size (1 to 49 members) (aOR 0.35 [95% CI 0.31 to 0.39]; p < 0.001), a high patient volume (greater than 500 Medicare patients) (aOR 0.82 [95% CI 0.70 to 0.95]; p = 0.01), and higher HCC score (aOR 0.79 [95% Cl 0.66 to 0.93]; p = 0.006) were associated with decreased odds of a perfect MIPS score.

CONCLUSION

Collectively, orthopaedic surgeons performed well in the second year of the MIPS, with 87% earning bonus payments. Among participating orthopaedic surgeons, individual reporting affiliation, small practice size, and more medically complex patient populations were associated with higher odds of receiving penalties and lower odds of earning a perfect score. Based on these findings, we recommend that individuals and orthopaedic surgeons in small group practices strive to forge partnerships with larger hospital practices with adequate ancillary staff to support quality reporting initiatives. Such partnerships may help relieve surgeons of growing administrative obligations and allow for maintained focus on direct patient care activities. Policymakers should aim to produce a shortened panel of performance measures to ensure more standardized comparison and less time and energy diverted from established clinical workflows. The current MIPS scoring methodology should also be amended with a complexity modifier to ensure fair evaluation of surgeons practicing in the safety net setting, or those treating patients with a high comorbidity burden.

Efeito do Checklist de cirurgia segura na incidência de eventos adversos: contribuições de um estudo nacional

RESUMO Objetivo: o estudo objetivou avaliar o efeito da utilização do checklist (CL) de cirurgia segura na incidência de eventos adversos (EA). Método: pesquisa transversal e retrospectiva com 851 pacientes submetidos a procedimentos cirúrgicos nos anos de 2012 (n=428) e 2015 (n=423), representando os períodos antes e após a implantação do CL. As incidências de EA para cada ano foram estimadas e posteriormente comparadas. Também foi analisada a associação entre a ocorrência do EA e a presença do CL no prontuário. Resultados: observou-se uma redução na estimativa pontual de EA de 13,6% (antes do uso do CL) para 11,8% (com a utilização do CL). No entanto, a diferença entre as proporções de EA nos períodos antes e após a utilização do CL não foi significativa (p=0,213). A ocorrência do EA mostrou associação significativa às seguintes características: risco anestésico do paciente, tempo de internação, tempo de cirurgia e classificação do procedimento segundo o potencial de contaminação. Considerando a proporção de óbitos ocorridos nas amostras, observou-se uma redução significativa de mortes (p=0,007) em pacientes cujo CL foi utilizado quando comparados aqueles sem o uso do instrumento. Não foi verificada associação significativa entre a presença do CL no prontuário e a ocorrência do EA de forma geral. Conclusão: a presença do CL no prontuário não garantiu uma redução esperada na incidência de EA. No entanto, acredita-se que o uso do instrumento integrado às demais estratégias de segurança do paciente possa melhorar a segurança/qualidade da assistência cirúrgica em longo prazo.

Analysis of 30 anaesthesia-related deaths in Germany between 2006 and 2015: An analysis of a closed claims database

BACKGROUND

Anaesthesiology is one of the safest fields in medicine today in relation to mortality. Deaths directly because of anaesthesia have fortunately now become rare exceptions. Nevertheless, important findings can still be drawn from the rare deaths that still occur.

OBJECTIVE

The aim of this study was to identify and analyse the causes of deaths related to anaesthesia alone over a 10-year period.

DESIGN

Retrospective structured analysis of a database of medical liability claims.

SETTING

Hospitals at all levels of care in Germany.

PATIENTS

The database of a large insurance broker included data for 81 413 completed liability claims over the 10-year period from 2006 to 2015. Among 1914 cases associated with anaesthetic procedures, 56 deaths were identified. Of these, 30 clearly involved anaesthesia (Edwards category 1) and were included in the evaluation.

INTERVENTIONS

None (retrospective database analysis).

MAIN OUTCOME MEASURES

Causes of anaesthesia-related death identified from medical records, court records, expert opinions and autopsy reports.

RESULTS

The 30 deaths were analysed in detail at the case and document level. They included high proportions of 'potentially avoidable' deaths, at 86.6%, and what are termed 'never events', at 66.7%. Problems with the airway were the cause in 40% and problems with correct monitoring in 20%. In addition, communication problems were identified as a 'human factor' in 50% of the cases.

CONCLUSION

The majority of the anaesthesia-related deaths investigated could very probably have been avoided with simple anaesthesiological measures if routine guidelines had been followed and current standards observed. Actions to be taken are inferred from these results, and recommendations are made. In future, greater care must be taken to ensure that the level of safety already achieved in anaesthesiology can be maintained despite demographic developments and increasing economic pressures.

Defining and Studying Errors in Surgical Care: A Systematic Review

OBJECTIVE

Our objective was to determine the extent surgical disciplines categorize, define, and study errors, then use this information to provide recommendations for both current practice and future study.

SUMMARY BACKGROUND DATA

The report "To Err is Human" brought the ubiquity of medical errors to public attention. Variability in subsequent literature suggests the true prevalence of error remains unknown.

METHODS

In January 2020, PubMed, the Cochrane Database of Systematic Reviews, and the Cochrane Central Register of Controlled Trials were searched. Only studies with Oxford Level of Evidence Level 3 or higher were included.

RESULTS

Of 3,064 studies, 92 met inclusion criteria: 6 randomized controlled trials, 4 systematic reviews, 24 cohort, 10 before-after, 35 outcome/audit, 5 cross sectional and 8 case-control studies. Over 15,933,430 patients and 162,113 errors were represented. There were 6 broad error categories, 13 different definitions of error, and 14 study methods.

CONCLUSIONS

Reported prevalence of error varied widely due to a lack of standardized categorization, definitions, and study methods. Future research should focus on immediately recognizing errors to minimize harm.

Major surgery leads to a proinflammatory phenotype: Differential gene expression following a laparotomy

BACKGROUND

The trauma of surgery is a neglected area of research. Our aim was to examine the differential expression of genes of stress, metabolism and inflammation in the major organs of a rat following a laparotomy.

MATERIALS AND METHODS

Anaesthetised Sprague-Dawley rats were randomised into baseline, 6-hr and 3-day groups (n = 6 each), catheterised and laparotomy performed. Animals were sacrificed at each timepoint and tissues collected for gene and protein analysis. Blood stress hormones, cytokines, endothelial injury markers and coagulation were measured.

RESULTS

Stress hormone corticosterone significantly increased and was accompanied by significant increases in inflammatory cytokines, endothelial markers, increased neutrophils (6-hr), higher lactate (3-days), and coagulopathy. In brain, there were significant increases in M1 muscarinic (31-fold) and α-1A-adrenergic (39-fold) receptor expression. Cortical expression of metabolic genes increased ∼3-fold, and IL-1β by 6-fold at 3-days. Cardiac β-1-adrenergic receptor expression increased up to 8.4-fold, and M2 and M1 muscarinic receptors by 2 to 4-fold (6-hr). At 3-days, cardiac mitochondrial gene expression (Tfam, Mtco3) and inflammation (IL-1α, IL-4, IL-6, MIP-1α, MCP-1) were significantly elevated. Haemodynamics remained stable. In liver, there was a dramatic suppression of adrenergic and muscarinic receptor expression (up to 90%) and increased inflammation. Gut also underwent autonomic suppression with 140-fold increase in IL-1β expression (3-days).

CONCLUSIONS

A single laparotomy led to a surgical-induced proinflammatory phenotype involving neuroendocrine stress, cortical excitability, immune activation, metabolic changes and coagulopathy. The pervasive nature of systemic and tissue inflammation was noteworthy. There is an urgent need for new therapies to prevent hyper-inflammation and restore homeostasis following major surgery.
