Surgical adverse events: a systematic review

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.

A Delphi study identifying operating room nurses' non-technical skills

AIM

To identify the non-technical skills of operating room nurses. This is the first empirical study that includes scrub and circulating operating room nurses.

DESIGN

A three-round modified online Delphi technique was used for this study.

METHODS

Eligible participants (n = 106) with a minimum of 2 years of operating room nursing experience were selected for the expert panel by self-recruitment from a population (N = 1640) of operating room nurses. Data were collected through online surveys, based on crew recourse management theory, between April and September 2020. Descriptive statistics analysis was used for the quantitative data, and deductive thematic analysis for the qualitative data. Consensus was determined using stability between the survey rounds.

RESULTS

A consensus was obtained to maintain the non-technical skills categories of situation awareness, leadership, decision-making, communication and teamwork. The qualitative data revealed several novel non-technical skills, including independent decision-making and leadership skills.

CONCLUSION

The non-technical skills of operating room nurses are more extensive than previously identified. This study has contributed to a verbalization of the tacit knowledge and skills of the operating room nurses. In addition, a list of non-technical skills that should be included in the education of operating room nurses to ensure patient safety in the operating room has been prepared.

IMPACT

This study addresses the lack of research on the non-technical skills of operating room nurses. When exploring the non-technical skills of scrub and circulating nurses, a diversity of novel non-technical skills was uncovered. This research will provide input for the development of a new training, supervision and assessment tool for accelerated development of the non-technical skills of operating room nurses. This contribution to the verbalization of the formerly tacit non-technical skills may facilitate clinical and formal teaching of such skills and may subsequently impact surgery-related patient safety.

Wirelessly operated bioelectronic sutures for the monitoring of deep surgical wounds

Monitoring surgical wounds post-operatively is necessary to prevent infection, dehiscence and other complications. However, the monitoring of deep surgical sites is typically limited to indirect observations or to costly radiological investigations that often fail to detect complications before they become severe. Bioelectronic sensors could provide accurate and continuous monitoring from within the body, but the form factors of existing devices are not amenable to integration with sensitive wound tissues and to wireless data transmission. Here we show that multifilament surgical sutures functionalized with a conductive polymer and incorporating pledgets with capacitive sensors operated via radiofrequency identification can be used to monitor physicochemical states of deep surgical sites. We show in live pigs that the sutures can monitor wound integrity, gastric leakage and tissue micromotions, and in rodents that the healing outcomes are equivalent to those of medical-grade sutures. Battery-free wirelessly operated bioelectronic sutures may facilitate post-surgical monitoring in a wide range of interventions.

Artificial intelligence and simulation in urology

INTRODUCTION AND OBJECTIVE

Artificial intelligence (AI) is in full development and its implementation in medicine has led to an improvement in clinical and surgical practice. One of its multiple applications is surgical training, with the creation of programs that allow avoiding complications and risks for the patient. The aim of this article is to analyze the advantages of AI applied to surgical training in urology.

MATERIAL AND METHODS

A literary research is carried out to identify articles published in English regarding AI applied to medicine, especially in surgery and the acquisition of surgical skills.

RESULTS

Surgical training has evolved over time thanks to AI. A model for surgical learning where skills are acquired in a progressive way while avoiding complications to the patient, has been created. The use of simulators allows a progressive learning, providing trainees with procedures that increase in number and complexity. On the other hand, AI is used in imaging tests for surgical or treatment planning.

CONCLUSION

Currently, the use of AI in daily clinical practice has led to progress in medicine, specifically in surgical training.

Surgical Teams' Attitudes About Surgical Safety and the Surgical Safety Checklist at 10 Years: A Multinational Survey

To assess health care professionals' attitudes on the Surgical Safety Checklist ("the Checklist") in resource-rich health systems and provide insights on strategies for optimizing Checklist use.

Background

In use for over a decade, the Checklist is a safety instrument aimed at improving operating room communication, teamwork, and evidence-based safety practices.

Methods

An online survey was sent to surgeons, nurses, and anesthesiologists in 5 high-income countries (Canada, the United States, the United Kingdom, Australia, and New Zealand). Survey results were analyzed using SPSS.

Results

A total of 2032 health care professionals completed the survey. Of these respondents, 47.6% were nurses, 70.5% were women, 65.1% were from the United States, and 50.0% had 20 years of experience or more in their role. Most respondents felt the Checklist positively impacted patient safety (70.9%), team communication (73.1%), and teamwork (58.9%). Only 50.3% of respondents were satisfied their team's use of the Checklist, and only 47.5% reported team members stopping to fully participate in the process. More nurses lacked confidence regarding their role in the Checklist process than surgeons and anesthesiologists combined (8.9% vs 4.3%). Fewer surgeons and anesthesiologists than nurses felt they received adequate training on the Checklist's use (57.8% vs 76.7%).

Conclusions

While most respondents perceive the Checklist as enhancing patient safety, not all surgical team members are actively engaging with its use. To enhance buy-in and meaningful use of the Checklist, health systems should provide more training on the Checklist with respect to its purpose and strengthening teamwork.

System Factors Affecting Patient Safety in the OR: An Analysis of Safety Threats and Resiliency

OBJECTIVE

The objective of this study is to determine the characteristics and frequency of intraoperative safety threats and resilience supports using a human factors measurement tool.

BACKGROUND

Human factors analysis can provide insight into how system elements contribute to intraoperative adverse events. Empiric evidence on safety threats and resilience in surgical practice is lacking.

METHODS

A cross-sectional study of 24 patients undergoing elective laparoscopic general surgery at a single center in the Netherlands from May to November, 2017 was conducted. Video, audio, and patient physiologic data from all included procedures were obtained through a multichannel synchronized recording device. Trained analysts reviewed the recordings and coded safety threats and resilience supports. The codes were categorized into 1 of 6 categories (person, task, tools and technology, physical environment, organization, and external environment).

RESULTS

A median of 14 safety threats [interquartile range (IQR) 11-16] and 12 resilience supports (IQR 11-16) were identified per case. Most safety threat codes (median 9, IQR 7-12) and resilience support codes (median 10, IQR 7-12) were classified in the person category. The organization category contained a median of 2 (IQR 1-2) safety threat codes and 2 (IQR 2-3) resilience support codes per case. The tools and technology category contributed a small number of safety threats (median 1 per case, IQR 0-1), but rarely provided resilience support.

CONCLUSIONS

Through a detailed human factors analysis of elective laparoscopic general surgery cases, this study provided a quantitative analysis of the existing safety threats and resilience supports in a modern endoscopic operating room.

Characterising the nature of clinical incidents reported across a tertiary health service: a retrospective audit

Objective Reducing the number of adverse patient safety incidents (PSIs) requires careful monitoring and active management processes. However, there is limited information about the association between hospital settings and the type of PSI. The aims of this study were to describe the severity, nature and characteristics of PSIs from an analysis of their incidence and to assess the relationships between the type of PSI and its setting. Methods A retrospective audit of a clinical incident management system database was conducted for a tertiary health service in Australia with 620000 residents. Records of PSIs reported for patients between 1 July 2017 and 30 June 2018 with Safety Assessment Codes (SAC) of PSIs were extracted from the clinical incident management system and analysed using descriptive and inferential statistics. PSIs involving paediatrics, mental health and primary care were excluded. Results In all, 4385 eligible PSIs were analysed: 24 SAC1, 107 SAC2 and 4254 SAC3 incidents. Across reported PSIs, the most common incidents related to skin injury (28.6%), medication (23.2%), falls (19.9%) and clinical process (8.5%). Falls were reported significantly more often in the medical division (χ2=43.85, P<0.001), whereas skin injury incidents were reported significantly more often in the surgical division (χ2=22.56, P<0.001). Conclusions A better understanding of the nature of PSIs and where they occur may lead to more targeted quality improvement strategies. What is known about this topic? Improving patient safety requires effective safety learning systems, which include incident reporting and management processes. Although incident reporting systems typically underestimate the incidence of iatrogenic harm, they do provide valuable opportunities to improve the future safety of health care. What does this paper add? This study reports the extent and severity of different types of PSIs that typically occur in a large tertiary hospital in Australia. The most common types of incidents are skin injury, falls, medication errors and clinical process. There are empirical associations between the type of PSI and clinical division (medical, surgical). What are the implications for practitioners? A greater understanding of the types of PSI and the settings in which they occur may inform the development of more targeted quality improvement strategies that potentially reduce their incidence.

Surgical Team Familiarity: An Integrative Review

The dynamic nature of perioperative care often brings unfamiliar clinicians together yet requires them to collectively provide complex health care in a challenging environment. In this review, we comprehensively evaluated evidence regarding surgical team familiarity and its relationship to surgical team performance. Using a comprehensive and iterative search strategy, we searched PubMed, Web of Science, PsycInfo, and EMBASE for surgical team familiarity manuscripts. We identified 598 manuscripts, 16 of which met our inclusion criteria. We found that surgical team familiarity is associated with improved performance for many metrics, including shorter total operative time, team member safety, decreased surgical errors and disruptions, reduced miscommunication, and fewer patient readmissions. Although additional research would be helpful, surgical managers should consider team familiarity and consistency in team membership when assigning staff members to surgical teams to optimize surgical care, decrease inefficiencies, and promote safe patient outcomes.

What works? Interventions to reduce readmission after hip fracture: A rapid review of systematic reviews

BACKGROUND

Hip fracture is a common serious injury in older people and reducing readmission after hip fracture is a priority in many healthcare systems. Interventions which significantly reduce readmission after hip fracture have been identified and the aim of this review is to collate and summarise the efficacy of these interventions in one place.

METHODS

In a rapid review of systematic reviews one reviewer (ELS) searched the Ovid SP version of Medline and the Cochrane Database of Systematic Reviews. Titles and abstracts of 915 articles were reviewed. Nineteen systematic reviews were included. (ELS) used a data extraction sheet to capture data on interventions and their effect on readmission. A second reviewer (RK) verified data extraction in a random sample of four systematic reviews. Results were not meta-analysed. Odds and risk ratios are presented where available.

RESULTS

Three interventions significantly reduce readmission in elderly populations after hip fracture: personalised discharge planning, self-care and regional anaesthesia. Three interventions are not conclusively supported by evidence: Oral Nutritional Supplementation, integration of care, and case management. Two interventions do not affect readmission after hip fracture: Enhanced Recovery pathways and comprehensive geriatric assessment.

CONCLUSIONS

Three interventions are most effective at reducing readmissions in older people: discharge planning, self-care, and regional anaesthesia. Further work is needed to optimise interventions and ensure the most at-risk populations benefit from them, and complete development work on interventions (e.g. interventions to reduce loneliness) and intervention components (e.g. adapting self-care interventions for dementia patients) which have not been fully tested yet.

Gathering Validity Evidence to Adapt the Non-technical Skills for Surgeons (NOTSS) Assessment Tool to the United States Context

BACKGROUND

Nontechnical skills are of increasing focus for safe and effective performance in the operating room. Assessment tools have been developed in Europe, Africa, and Asia but not adapted to the unique aspects of surgical delivery in the United States. Our objective was to use the Non-Technical Skills for Surgeons (NOTSS) assessment tool as a basis to establish consensus on essential nontechnical skills for surgical trainees and practicing surgeons in the U.S surgical context.

STUDY DESIGN

A mixed-methods research design was used in the form of a modified Delphi process to build consensus on essential NOTSS. A panel of surgical experts from hospitals across the U.S used this iterative process in 4 rounds to generate, rate, and classify behaviors. The primary outcome was consensus on behaviors as being essential for surgeons to achieve the best patient outcomes in the operating room, with a median rating of ≥6 on a 7-point scale for inclusion.

RESULTS

A total of 10 surgical experts participated. One hundred and thirty eight behaviors were generated in Round 1, and reduced to 100 behaviors in Rounds 2 and 3 based on application of inclusion criteria. The final skill list consisted of behaviors in Situation Awareness (n = 26), Decision Making (n = 18), Teamwork (n = 25), and Leadership (n = 31). No additional NOTSS categories or elements emerged from the analysis. In Round 4, all 100 behaviors were successfully grouped into 12 nontechnical skills elements. Labels and definitions were reworded to reflect the U.S. context, and an appropriate assessment scale was selected.

CONCLUSIONS

A panel of surgical experts from across the U.S. reached consensus on the essential NOTSS to achieve the best patient outcomes in the operating room. These behaviors form an empirical basis for the first context-specific nontechnical skills assessment and training tool for practicing surgeons in the U.S.

Relationship Between Perioperative Outcomes Used for Profiling Hospital Noncardiac Surgical Quality

BACKGROUND

Risk-adjusted morbidity and mortality are commonly used by national surgical quality improvement (QI) programs to measure hospital-level surgical quality. However, the degree of hospital-level correlation between mortality, morbidity, and other perioperative outcomes (like reoperation) collected by contemporary surgical QI programs has not been well-characterized.

MATERIALS AND METHODS

Veterans Affairs (VA) Surgical Quality Improvement Program (VASQIP) data (2015-2016) were used to evaluate hospital-level correlation in performance between risk-adjusted 30-d mortality, morbidity, major morbidity, reoperation, and 2 composite outcomes (1- mortality, major morbidity, or reoperation; 2- mortality or major morbidity) after noncardiac surgery. Correlation between outcomes rates was evaluated using Pearson's correlation coefficient. Correlation between hospital risk-adjusted performance rankings was evaluated using Spearman's correlation.

RESULTS

Based on a median of 232 [IQR 95-331] quarterly surgical cases abstracted by VASQIP, statistical power for identifying 30-d mortality outlier hospitals was estimated between 3.3% for an observed-to-expected ratio of 1.1 and 45.7% for 3.0. Among 230,247 Veterans who underwent a noncardiac operation at 137 VA hospitals, there were moderate hospital-level correlations between various risk-adjusted outcome rates (highest r = 0.40, mortality and composite 1; lowest r = 0.32, mortality and morbidity). When hospitals were ranked based on performance, there was low-to-moderate correlation between rankings on the various outcomes (highest ρ = 0.47, mortality and composite 1; lowest ρ = 0.37, mortality and major morbidity).

CONCLUSIONS

Modest hospital-level correlations between perioperative outcomes suggests it may be difficult to identify high (or low) performing hospitals using a single measure. Additionally, while composites of currently measured outcomes may be an efficient way to improve analytic sample size (relative to evaluations based on any individual outcome), further work is needed to understand whether they provide a more robust and accurate picture of hospital quality or whether evaluating performance across a portfolio of individual measures is most effective for driving QI.

Innovations in Urologic Surgical Training

PURPOSE OF REVIEW

This review aims to summarize innovations in urologic surgical training in the past 5 years.

RECENT FINDINGS

Many assessment tools have been developed to objectively evaluate surgical skills and provide structured feedback to urologic trainees. A variety of simulation modalities (i.e., virtual/augmented reality, dry-lab, animal, and cadaver) have been utilized to facilitate the acquisition of surgical skills outside the high-stakes operating room environment. Three-dimensional printing has been used to create high-fidelity, immersive dry-lab models at a reasonable cost. Non-technical skills such as teamwork and decision-making have gained more attention. Structured surgical video review has been shown to improve surgical skills not only for trainees but also for qualified surgeons. Research and development in urologic surgical training has been active in the past 5 years. Despite these advances, there is still an unfulfilled need for a standardized surgical training program covering both technical and non-technical skills.

[Teamwork and stress in routine interventions: an observational study of multiprofessional OR teams]

Hintergrund

Effektive interprofessionelle Teamarbeit im Operationssaal (OP) und intraoperativer Stress sind von großer Bedeutung für Patientensicherheit und Versorgungsqualität. Dennoch gibt es nur wenige systematische Studien zum Zusammenhang von Teamarbeit im OP und Arbeitsstress.

Ziele der Arbeit

Untersuchung des Zusammenhangs von Teamarbeit und empfundenem Stress bei Routineeingriffen – für das OP-Team als Gesamtheit sowie für die einzelnen Professionen Chirurgie, Anästhesie und Pflege.

Material und Methoden

Durchgeführt wurde eine Mehrmethodenstudie bestehend aus Expertenbeobachtungen mittels eines standardisierten Beobachtungsinstruments (OTAS-D) und systematischer Selbstberichte des gesamten OP-Teams. Erfasst wurden 64 elektive Routineeingriffe unterschiedlicher chirurgischer Fachbereiche. Die statistischen Zusammenhangsanalysen unter Kontrolle prozeduraler Einflussfaktoren wurden mit „Mixed-effects“-Regressionsmodellen berechnet.

Ergebnisse

Die Güte der intraoperativen Teamarbeit lag auf mittlerem Niveau. Der situative Stress während des Eingriffs wurde durch die Befragten eher auf niedrigerem Niveau berichtet, mit signifikanten Unterschieden zwischen den Professionen Chirurgie, Pflege und Anästhesie. Mitglieder des chirurgischen Teams berichteten im Durchschnitt die höchsten Stressniveaus. Ein genereller Zusammenhang zwischen Teamarbeit und Stresserleben konnte nicht beobachtet werden, allerdings für die einzelnen Professionen: Für das chirurgische Team ergaben sich signifikante, positive Zusammenhänge, sowie für die Teamarbeitsdimensionen Zusammenarbeit und Führung. Signifikante negative Zusammenhänge ergaben sich für das Pflegeteam hinsichtlich der Qualität der interdisziplinären Teamarbeit insgesamt sowie für die Teamarbeitsdimension Team-Monitoring.

Diskussion

Die Effekte interprofessioneller Zusammenarbeit im OP auf subjektives Stressempfinden bei Routineeingriffen hängen von Professionszugehörigkeit, Aufgabe und Tätigkeit ab. Weitere Forschungsarbeit ist notwendig, inwiefern gute Teamarbeit bei Routineeingriffen innerhalb und über die Professionen hinweg intraoperativen Stress beeinflusst.

Adverse Event Reporting in Otolaryngology

OBJECTIVES

Adverse events are common occurrences in hospitals that detract from quality of care. There are few data on errors in otolaryngology (ENT) and even fewer data comparing ENT to other services.

METHODS

We retrospectively reviewed adverse event data collected across a regional hospital network from July 2014 to August 2017. We examined categories of adverse events that occurred most commonly in ENT and compared the number of adverse events reported in ENT to those reported across all other departments. Descriptive analysis and the paired t test were used to analyze the data.

RESULTS

Two hundred ninety-one adverse events were reported in ENT departments during the period studied compared to 58,219 events reported across all other specialties. In ENT, the most commonly reported adverse events occurred in the perioperative setting, followed by issues regarding equipment and medical devices and, lastly, airway management. Across all other departments, the most common categories included medication and fluid errors, falls, and safety and security events. ENT departments had significantly higher proportions of perioperative and airway management errors and significantly lower proportions of events related to diagnosis and treatment (P = .004), falls (P < .001), lab results and specimens (P = .001), medication and fluids (P < .001), and safety and security (P < .001).

CONCLUSION

Perioperative and airway management errors occur with a statistically higher frequency in ENT compared to other in-patient and out-patient departments across hospitals. It is important to analyze adverse event reporting in surgical specialties to ensure the development of appropriate quality initiatives.

Adaptive threshold-based alarm strategies for continuous vital signs monitoring

Continuous vital signs monitoring in post-surgical ward patients may support early detection of clinical deterioration, but novel alarm approaches are required to ensure timely notification of abnormalities and prevent alarm-fatigue. The current study explored the performance of classical and various adaptive threshold-based alarm strategies to warn for vital sign abnormalities observed during development of an adverse event. A classical threshold-based alarm strategy used for continuous vital signs monitoring in surgical ward patients was evaluated retrospectively. Next, (combinations of) six methods to adapt alarm thresholds to personal or situational factors were simulated in the same dataset. Alarm performance was assessed using the overall alarm rate and sensitivity to detect adverse events. Using a wireless patch-based monitoring system, 3999 h of vital signs data was obtained in 39 patients. The clinically used classical alarm system produced 0.49 alarms/patient/day, and alarms were generated for 11 out of 18 observed adverse events. Each of the tested adaptive strategies either increased sensitivity to detect adverse events or reduced overall alarm rate. Combining specific strategies improved overall performance most and resulted in earlier presentation of alarms in case of adverse events. Strategies that adapt vital sign alarm thresholds to personal or situational factors may improve early detection of adverse events or reduce alarm rates as compared to classical alarm strategies. Accordingly, further investigation of the potential of adaptive alarms for continuous vital signs monitoring in ward patients is warranted.

Tools for Assessing the Performance of Pediatric Perioperative Teams During Simulated Crises: A Psychometric Analysis of Clinician Raters' Scores

INTRODUCTION

The pediatric perioperative setting is a dynamic clinical environment where multidisciplinary interprofessional teams interact to deliver complex care to patients. This environment requires clinical teams to possess high levels of complex technical and nontechnical skills. For perioperative teams to identify and maintain clinical competency, well-developed and easy-to-use measures of competency are needed.

METHODS

Tools for measuring the technical and nontechnical performance of perioperative teams were developed and/or identified, and a group of raters were trained to use the instruments. The trained raters used the tools to assess pediatric teams managing simulated emergencies. A psychometric analysis of the trained raters' scores using the different instruments was performed and the agreement between the trained raters' scores and a reference score was determined.

RESULTS

Five raters were trained and scored 96 recordings of perioperative teams managing simulated emergencies. Scores from both technical skills assessment tools demonstrated significant reliability within and between ratings with the scenario-specific performance checklist tool demonstrating greater interrater agreement than scores from the global rating scale. Scores from both technical skills assessment tools correlated well with the other and with the reference standard scores. Scores from the Team Emergency Assessment Measure nontechnical assessment tool were more reliable within and between raters and correlated better with the reference standard than scores from the BARS tool.

CONCLUSIONS

The clinicians trained in this study were able to use the technical performance assessment tools with reliable results that correlated well with reference scores. There was more variability between the raters' scores and less correlation with the reference standard when the raters used the nontechnical assessment tools. The global rating scale used in this study was able to measure the performance of teams across a variety of scenarios and may be generalizable for assessing teams in other clinical scenarios. The Team Emergency Assessment Measure tool demonstrated reliable measures when used to assess interprofessional perioperative teams in this study.

Student supervision using the Scrub Practitioners' List of Intraoperative Non-Technical Skills (SPLINTS-no): A qualitative study

BACKGROUND

The importance of non-technical skills in the prevention of adverse events in the operating room is well documented through research. With the increased attention to non-technical skills, the need for structured training to support the development of such skills has emerged. The Scrub Practitioners' List of Intraoperative Non-Technical Skills (SPLINTS) is an instrument for structuring observation as well as rating and feedback of non-technical skills for operating room nurses, and it can be used for student supervision and self-reflection. SPLINTS-no is the Norwegian translation and adaptation of SPLINTS.

OBJECTIVE

To explore the experiences of operating room nurse preceptors using SPLINTS-no in the supervision of operating room students' non-technical skills.

DESIGN

An explorative qualitative design was used.

METHODS

Data were collected using semi-structured qualitative interviews with 10 operating room nurse preceptors in a Norwegian university hospital. The data were analysed by inductive qualitative content analysis.

RESULTS

The operating room nurse preceptors experienced that the use of SPLINTS-no had an impact on the quality of student supervision. They improved their supervision competencies, and the use of SPLINTS-no contributed to consistency in observation and supervision. There were also findings supporting that reflection over non-technical skills contributed to building an increased awareness of these skills.

CONCLUSIONS

SPLINTS-no has an impact on clinical student supervision through an increased awareness on non-technical skills. It is well accepted by the operating room nurses as a supportive tool in the supervision of non-technical skills of student operating room nurses during clinical placement.

"Who wants me to do what?" varied expectations from key stakeholder groups in the surgical intensive care unit creates a challenging learning environment

BACKGROUND

Surgical intensive care units (SICU) require complex care from a multi-disciplinary team. Frequent changes in team members can lead to shifting expectations for junior general surgical trainees, which creates a challenging working and learning environment. We aim to identify expectations of junior surgery trainee's medical knowledge and technical/non-technical skills at the start of their SICU rotation. We hypothesize that expectations will not be consistent across SICU stakeholder groups.

METHODS

Twenty-eight individual semi-structured interviews were conducted with six SICU stakeholder groups at a medium-sized academic hospital. Expectations were identified from interview transcripts. Frequency counts were analyzed.

RESULTS

Forty-one expectations were identified. 4 expectations were identified by a majority of interviewees. Most expectations were identified by 7 or fewer interviewees. 23 (53%) expectations were shared by at least one stakeholder group. 2 (8%) expectations were shared by all groups.

CONCLUSIONS

SICU stakeholder groups identified ten medical knowledge, ten technical skill, and three non-technical skill expectations. Yet, few expectations were shared among the groups. Thus, SICU stakeholder groups have disparate expectations for surgery trainees in our SICU.

Preventable medication harm across health care settings: a systematic review and meta-analysis

BACKGROUND

Mitigating or reducing the risk of medication harm is a global policy priority. But evidence reflecting preventable medication harm in medical care and the factors that derive this harm remain unknown. Therefore, we aimed to quantify the prevalence, severity and type of preventable medication harm across medical care settings.

METHODS

We performed a systematic review and meta-analysis of observational studies to compare the prevalence of preventable medication harm. Searches were carried out in Medline, Cochrane library, CINAHL, Embase and PsycINFO from 2000 to 27 January 2020. Data extraction and critical appraisal was undertaken by two independent reviewers. Random-effects meta-analysis was employed followed by univariable and multivariable meta-regression. Heterogeneity was quantified using the I² statistic, and publication bias was evaluated.

PROSPERO

CRD42020164156.

RESULTS

Of the 7780 articles, 81 studies involving 285,687 patients were included. The pooled prevalence for preventable medication harm was 3% (95% confidence interval (CI) 2 to 4%, I² = 99%) and for overall medication harm was 9% (95% CI 7 to 11%, I² = 99.5%) of all patient incidence records. The highest rates of preventable medication harm were seen in elderly patient care settings (11%, 95% 7 to 15%, n = 7), intensive care (7%, 4 to 12%, n = 6), highly specialised or surgical care (6%, 3 to 11%, n = 13) and emergency medicine (5%, 2 to 12%, n = 12). The proportion of mild preventable medication harm was 39% (28 to 51%, n = 20, I² = 96.4%), moderate preventable harm 40% (31 to 49%, n = 22, I² = 93.6%) and clinically severe or life-threatening preventable harm 26% (15 to 37%, n = 28, I² = 97%). The source of the highest prevalence rates of preventable harm were at the prescribing (58%, 42 to 73%, n = 9, I² = 94%) and monitoring (47%, 21 to 73%, n = 8, I² = 99%) stages of medication use. Preventable harm was greatest in medicines affecting the 'central nervous system' and 'cardiovascular system'.

CONCLUSIONS

This is the largest meta-analysis to assess preventable medication harm. We conclude that around one in 30 patients are exposed to preventable medication harm in medical care, and more than a quarter of this harm is considered severe or life-threatening. Our results support the World Health Organisation's push for the detection and mitigation of medication-related harm as being a top priority, whilst highlighting other key potential targets for remedial intervention that should be a priority focus for future research.

Management of Common Postoperative Complications

Postoperative complications are common. Major guidelines have been published on stratifying and managing adverse cardiovascular events and thromboembolic events, but there is often less literature supporting management of other, more common, postoperative complications, including acute kidney injury, gastrointestinal complications, postoperative anemia, fever, and delirium. These common conditions are frequently seen in hospital and can contribute to longer lengths of stay and rising health care costs. These complications are often due to the interplay between both patient-specific and surgery-specific risk factors. Identifying these risk factors, while addressing and optimizing modifiable risks, can mitigate the likelihood of developing these postoperative complications. Often, a multidisciplinary approach, including care team members through all phases of the surgical encounter, is needed. Cardiovascular and thrombotic complications have been addressed in prior articles in this perioperative series. We aim to cover other common postoperative complications, such as acute renal failure, postoperative gastrointestinal complications, anemia, fever, and delirium that often contribute to longer lengths of stay, rising health care costs, and increased morbidity and mortality for patients.

Health Care Failure Mode and Effect Analysis in the Operating Room Setting

OBJECTIVES

Operating rooms (ORs) and surgical settings are potential sources of sentinel adverse events. To better understand the characteristics of errors in OR processes, we performed prospective risk analysis.

METHODS

The study was mixed qualitative and quantitative research. We used the Healthcare Failure Mode and Effect Analysis (HFMEA) method to analyze the selected perioperative, operative, and postoperative processes in the OR via a 2-round Delphi technique. We identified the most prominent failure modes according to a Hazard Decision Matrix, analyzed and categorized proposed possible causes, and provided solutions to mitigate hazard scores.

RESULTS

Ten important processes and 7 subprocesses within the OR were selected and mapped, and 187 failure modes were identified and scored on the basis of severity and probability. A total of 36 potential failure modes were highlighted as high-risk failures and moved to decision trees for further analyses.

CONCLUSION

Developing policy for the familiarization of new personnel designing a checklist for accurate gases counting; drafting comprehensive presurgical posters; preparing all necessary equipment in difficult intubation; developing instruction for monthly checking of the OR equipment; and developing the evaluation criteria of staff performance are examples of solutions that are proposed to improve the quality of OR processes.

Identification of Meaningful Data for Providing Real-Time Intraoperative Feedback in Laparoscopic Surgery Using Delphi Analysis

Background. Surgeons are at risk of being overwhelmed with information while performing surgery. Initiatives focusing on the use of medical data in the operating room are on the rise. Currently, these initiatives require postprocessing of data. Although highly informative, data cannot be used to influence preventable error in real time. Ideally, feedback is provided preemptive. Aims. First, to identify which information is considered to be relevant for real-time feedback during laparoscopic surgery according to surgeons. Second, to identify the optimal routing for providing such feedback, and third, to decide on optimal timing for feedback to alarm users during laparoscopic surgery. Methods. A Delphi study of 3 iterations was conducted within the Amsterdam UMC, location AMC. A total of 25 surgeons and surgical residents performing laparoscopy were surveyed using 5-point Likert scales. Consensus was obtained when 80% of answers fitted the same answering category. Results. Delphi round 1 resulted in 198 unique ideas within 5 scenarios. After round 3, consensus was obtained on 102 items. Feedback most relevant during laparoscopic surgery refers to equipment like the gas insufflator, diathermy, and suction device. Feedback should be delivered via an additional monitor. Surgeons want to be instantly alarmed about aberrations in patients' vital parameters or combinations of vital parameters, preferably via a designated section on a monitor in their field of vision. Conclusions. Surgeons performing laparoscopy are uniform in their opinion that they need to be alarmed immediately when patients' vital parameters are becoming aberrant. Surgeons state that information regarding supporting equipment is best displayed on an additional monitor.

Illuminating the dark spaces of healthcare with ambient intelligence

Advances in machine learning and contactless sensors have given rise to ambient intelligence-physical spaces that are sensitive and responsive to the presence of humans. Here we review how this technology could improve our understanding of the metaphorically dark, unobserved spaces of healthcare. In hospital spaces, early applications could soon enable more efficient clinical workflows and improved patient safety in intensive care units and operating rooms. In daily living spaces, ambient intelligence could prolong the independence of older individuals and improve the management of individuals with a chronic disease by understanding everyday behaviour. Similar to other technologies, transformation into clinical applications at scale must overcome challenges such as rigorous clinical validation, appropriate data privacy and model transparency. Thoughtful use of this technology would enable us to understand the complex interplay between the physical environment and health-critical human behaviours.

Structured Feedback Enhances Compliance with Operating Room Debriefs

BACKGROUND

Surgical debriefs help reduce preventable errors in the operating room (OR) leading to patient injury. However, compliance with debriefs remains poor. The objective of this study was to evaluate the role of structured feedback to surgeons in improving compliance with and quality of surgical debriefs.

MATERIALS AND METHODS

Surgical cases at an 875-bed urban teaching hospital from January-June 2019 were audited via audio/video recording to evaluate debrief performance. Debriefs were evaluated for clinical completeness and teamwork quality via two structured forms. Surgeons received an evaluation of their debrief performance at two time points during the study period (February and April). Univariate and mixed-effects regression analyses were used to assess changes in debrief compliance and quality over time.

RESULTS

A total of 878 surgical cases performed by 61 surgeons were reviewed: 198 (22.6%) cases during Period 1 (P1), 371 (42.3%) P2, and 309 (35.1%) P3. The rate at which a debrief occurred was 62.1% in P1, 73.0% in P2, and 82.2% in P3 (P < 0.001). Debriefs were 1.96 (95% CI 1.31-2.95, P = 0.001) times more likely to be completed during P2 and 3.21 (95% CI 2.07-5.04, P < 0.001) times more likely during P3 compared to P1. The percent of debriefs initiated by the lead surgeon increased from 59.8% in P1, to 80.0% in P2, to 81.5% in P3 (P < 0.001).

CONCLUSIONS

Providing structured feedback to surgeons on their debrief performance was associated with improvements in compliance and completeness with debriefing protocols, OR teamwork and communication, and leadership and accountability from the lead surgeons.

Accuracy and usefulness in assessing proficiency of the observational clinical human reliability assessment checklist of the open inguinal hernia repair procedure: A cross-sectional study

BACKGROUND

The Observational Clinical Human Reliability Assessment (OCHRA) can be used to score errors during surgical procedures. To construct an OCHRA-checklist, steps, substeps, and hazards of a surgical procedure need to be defined. A step-by-step framework was developed to segment surgical procedures into steps, substeps, and hazards. The first aim of this study was to investigate if the step-by-step framework could be used to construct an accurate Lichtenstein open inguinal hernia repair (LOIHR) stepwise description. The second aim was to investigate if the OCHRA-checklist based on this stepwise description was accurate and useful for surgical training and assessment.

MATERIALS AND METHODS

Ten expert surgeons rated statements regarding the accuracy of the LOIHR stepwise description, the accuracy, and the usefulness of the LOIHR OCHRA-checklist (eight, seven, and six statements, respectively) using a 5-point Likert scale. One-sample Wilcoxon signed-rank test was used to compare the outcomes to the neutral value of 3.

RESULTS

The accuracy of the stepwise description and the accuracy and usefulness of the OCHRA-checklist were rated statistically significantly higher than the neutral value of 3 (median 4.75 [5.00-4.00] with p = .009, median 5.00 [5.00-4.00] with p = .012, median 4.00 [5.00-4.00] with p = .047, respectively). The experts rated the OCHRA-checklist to be useful for the training (5.00 [5.00-4.00], p = .009), and assessment (4.50 [5.00-4.00], p = .010) of surgical residents.

CONCLUSION

This preliminary study showed that the stepwise LOIHR description constructed using the step-by-step framework was found to be accurate. The LOIHR OCHRA-checklist developed using the stepwise description was also accurate, and particularly useful for the training and assessment of proficiency of surgical residents.

Trauma of major surgery: A global problem that is not going away

Globally, a staggering 310 million major surgeries are performed each year; around 40 to 50 million in USA and 20 million in Europe. It is estimated that 1-4% of these patients will die, up to 15% will have serious postoperative morbidity, and 5-15% will be readmitted within 30 days. An annual global mortality of around 8 million patients places major surgery comparable with the leading causes of death from cardiovascular disease and stroke, cancer and injury. If surgical complications were classified as a pandemic, like HIV/AIDS or coronavirus (COVID-19), developed countries would work together and devise an immediate action plan and allocate resources to address it. Seeking to reduce preventable deaths and post-surgical complications would save billions of dollars in healthcare costs. Part of the global problem resides in differences in institutional practice patterns in high- and low-income countries, and part from a lack of effective perioperative drug therapies to protect the patient from surgical stress. We briefly review the history of surgical stress and provide a path forward from a systems-based approach. Key to progress is recognizing that the anesthetized brain is still physiologically 'awake' and responsive to the sterile stressors of surgery. New intravenous drug therapies are urgently required after anesthesia and before the first incision to prevent the brain from switching to sympathetic overdrive and activating secondary injury progression such as hyperinflammation, coagulopathy, immune activation and metabolic dysfunction. A systems-based approach targeting central nervous system-mitochondrial coupling may help drive research to improve outcomes following major surgery in civilian and military medicine.

Outcome quality standards for surgery of colorectal liver metastasis

PURPOSE

Liver metastases are the most common malignant solid liver lesions, approximately 40% of which stem from colorectal tumors. Liver resection is currently the only curative treatment for colorectal cancer liver metastases (CRLM). However, there is a lack of consensus criteria to assess the results of this treatment. In order to evaluate the quality of surgical outcomes, it is necessary to identify quality indicators (QIs) and their corresponding quality standards (QS). We propose a simple method to determine QI and QS in CRLM surgery (CRLMS) and establish acceptable quality limits (AQL) for each QI.

MATERIAL AND METHODS

A systematic review of CRLMS results published from 2006 to 2016. Clinical guidelines, consensus conferences, and publications related to the CRLMS were reviewed to identify and select QIs. Once selected, a new review of the papers including the results of at least one of the QIs was performed. Statistical process control (SPC) method was applied to calculate the QS and AQL of each QI. The limits of variability were established from mean and confidence intervals at 95% and 99.8%.

RESULTS

The most relevant QIs and its AQLs were postoperative mortality (2%, < 4.5%), overall postoperative morbidity (33%, < 41%), liver failure (5%, < 8%), postoperative hemorrhage (1%, < 3%), biliary fistula (6%, < 10%), reoperation (3%, < 6%), R1 resection margins (18%, < 25%), and overall survival at 12 and 60 months (84%, > 77%; and 34%, > 25%, respectively).

CONCLUSIONS

Despite its limitations, the present study constitutes the most extensive scientific evidence to date on QI and AQL in CRLMS and may constitute a reference in future studies.

Postoperative Remote Monitoring with a Transcutaneous Biosensing Patch: Preliminary Evaluation of Data Collection

Introduction. Connected systems transmitting vital parameters could well represent a tool to shorten postoperative hospital stay while providing continuous remote patient monitoring and potentially detect the onset of complications. Our aim was to analyze the functionality of a transcutaneous biosensing data collection patch in morbidly obese patients. Materials and Methods. An adhesive patch (The HealthPatch MD™) was applied to patients' chests postoperatively. The patch was connected to a tablet via a bluetooth network to collect the heart rate, respiratory rate, skin temperature, and posture recognition data. The tablet conveyed data to a secure health data central server by means of a WiFi or 3G/4G transmission. Data were stored in a digital health platform to which health care professionals could connect. The evaluation focused on the volume, quality, and security of data transmission. A pilot phase involved 10 patients. Thirty-three additional patients undergoing bariatric surgery were included in the experimental phase. Results. The mean length of stay was 2.28 days (range: 2-5 days). The mean time of patch application was 51 ± 25.2 hours per patient (range: 19-139 hours), totalizing 1,683 hours of recording for the 33 patients included. During this time, a total of 7.562.531 data measurement points were collected and transmitted to the e-health platform via the patch. Two total disconnections and two partial disconnections were observed. The acquisition of patient postural data was unreliable. Conclusions. Connected telemetry for remote postoperative monitoring is promising. However, it is still limited by data transmission problems.

Surgical Data Recording Technology: A Solution to Address Medical Errors?

: Reducing preventable medical errors remains a universal goal, yet implementing effective solutions remains a challenge. The development of surgical data recording technology shows promise to generate robust qualitative and quantitative data in the surgical theater. These data can allow physicians and their teams to capture specific sources of error and implement corrective interventions. Surgical data recording technology encompasses rudimentary data tabulation on notecards, to integrated audio-video systems containing cameras, microphones, and sensors, capturing and synthesizing intraoperative, environmental, and instrumentation information, along with devices tailored to robotic surgical systems. There is growing interest in the implementation of such technology in medical centers, particularly in the United States, Canada, and Europe, but existing medicolegal and regulatory challenges necessitate further research and clinical assessment in order for this technology to facilitate improved surgical patient safety.

Management of ophthalmic surgical instruments and processes optimization: mixed method study

AIM

Analysis of the use of ophthalmic instruments during surgical procedures in order to propose a material management method.

METHOD

Mixed method study, sequential exploratory design, performed from January to June 2015, at a university hospital in southern Brazil. First, a qualitative approach was held from brainstorming and field observation. Themes were grouped into thematic categories. By connection, the quantitative stage happened through matrix arrangement and linear programming, culminating in the instrument management proposal.

RESULTS

Given categories - instruments reorganization according to the time of the surgical procedure and the need surgical instruments for in each procedure - guided the definition of existing restrictions and application of mathematical models. There was an average reduction of 13.10% in the number of surgical instruments per tray and an increase of 17.88% in surgical production.

FINAL CONSIDERATIONS

This proposal allowed the rationalization and optimization of ophthalmic instruments, favoring sustainability of the organization.

Implementing structured team debriefing using a Black Box in the operating room: surveying team satisfaction

Background

Surgical safety may be improved using a medical data recorder (MDR) for the purpose of postoperative team debriefing. It provides the team in the operating room (OR) with the opportunity to look back upon their joint performance objectively to discuss and learn from suboptimal situations or possible adverse events. The aim of this study was to investigate the satisfaction of the OR team using an MDR, the OR Black Box®, in the OR as a tool providing output for structured team debriefing.

Methods

In this longitudinal survey study, 35 gastro-intestinal laparoscopic operations were recorded using the OR Black Box® and the output was subsequently debriefed with the operating team. Prior to study, a privacy impact assessment was conducted to ensure alignment with applicable legal and regulatory requirements. A structured debrief model and an OR Back Box® performance report was developed. A standardized survey was used to measure participant’s satisfaction with the team debriefing, the debrief model used and the performance report. Factor analysis was performed to assess the questionnaire’s quality and identified contributing satisfaction factors. Multivariable analysis was performed to identify variables associated with participants’ opinions.

Results

In total, 81 team members of various disciplines in the OR participated, comprising 35 laparoscopic procedures. Mean satisfaction with the OR Black Box® performance report and team debriefing was high for all 3 identified independent satisfaction factors. Of all participants, 98% recommend using the OR Black Box® and the outcome report in team debriefing.

Conclusion

The use of an MDR in the OR for the purpose of team debriefing is considered to be both beneficial and important. Team debriefing using the OR Black Box® outcome report is highly recommended by 98% of team members participating.

Risk Analysis for Patient Safety in Surgical Departments: Cross-Sectional Design Usefulness

(1) Background: Identifying and measuring adverse events (AE) is a priority for patient safety, which allows us to define and prioritise areas for improvement and evaluate and develop solutions to improve health care quality. The aim of this work was to determine the prevalence of AEs in surgical and medical-surgical departments and to know the health impact of these AEs. (2) Methods: A cross-sectional study determining the prevalence of AEs in surgical and medical-surgical departments was conducted and a comparison was made among both clinical areas. A total of 5228 patients were admitted in 58 hospitals in Argentina, Colombia, Costa Rica, Mexico, and Peru, within the Latin American Study of Adverse Events (IBEAS), led by the Spanish Ministry of Health, the Pan American Health Organization, and the WHO Patient Safety programme. (3) Results: The global prevalence of AEs was 10.7%. However, the prevalence of AEs in surgical departments was 11.9%, while in medical-surgical departments it was 8.9%. The causes of these AEs were associated with surgical procedures (38.6%) and nosocomial infections (35.4%). About 60.6% of the AEs extended hospital stays by 30.7 days on average and 25.8% led to readmission with an average hospitalisation of 15 days. About 22.4% resulted in death, disability, or surgical reintervention. (4) Conclusions: Surgical departments were associated with a higher risk of experiencing AEs.

Engaging the patient and family in the surgical safety process utilizing

BACKGROUND

Owing to the vulnerable nature of children, parental/caregiver engagement in surgical safety is a crucial aspect of care. Historically, the surgical safety process has been isolated from parent involvement. The digital, tablet-based surgical safety application, SafeStart, requires parent participation and provides multiple instances of verification of patient safety information from preoperative clinic visit, to perioperative care, and into the operating room.

METHOD

The SafeStart application was utilized for 100 pediatric general surgery patients in an IRB approved prospective study. Parent assessments of the surgical consent and safety processes were collected in pre- and postoperative surveys with a 100% response rate. Standard consent forms were used and compared as a control.

RESULTS

Only 31% of parents had knowledge of the surgical safety checklist process prior to their exposure to the study. 96% of the parents reported that the SafeStart patient portal was easy to use. A majority would prefer SafeStart to the standard consent process.

CONCLUSION

The SafeStart program connected the surgical safety process from the preoperative clinic visit through postoperative care. Parent's preferred SafeStart to the standard surgical safety checklist and consent process, felt that they were instrumental in protecting their child's safety, and would recommend SafeStart for the surgical care of others.

Current Status of Simulation Training in Urology: A Non-Systematic Review

Simulation has emerged as an effective solution to increasing modern constraints in surgical training. It is recognized that a larger proportion of surgical complications occur during the surgeon's initial learning curve. The simulation takes the learning curve out of the operating theatre and facilitates training in a safe and pressure-free environment whilst focusing on patient safety. The cost of simulation is not insignificant and requires commitment in funding, human resources and logistics. It is therefore important for trainers to have evidence when selecting various simulators or devices. Our non-systematic review aims to provide a comprehensive up-to-date picture on urology simulators and the evidence for their validity. It also discusses emerging technologies and future directions. Urologists should embed evidence-based simulation in training programs to shorten learning curves while maintaining patient safety and work should be directed toward a validated and agreed curriculum.

Acceptable errors with evaluation of 577 cervical pedicle screw placements

PURPOSE

Cadaveric studies have discouraged the use of cervical pedicle screws (CPS) with high misplacement rates. However, the clinical results show minimal screw-related complications and have highlighted the advantages of using CPS. We introduce "acceptable errors classification" in the placement of cervical pedicle screws to bridge the gap between the high radiological perforation rates and low clinical complications.

METHODS

Ninety-nine patients with average age of 49 years were operated between December 2011 and June 2017 using CPS. Sixty-one patients had trauma, 33 had CSM, 3 had tumors and 2 patients had fracture with ankylosing spondylitis. The screws were inserted using the medial cortical pedicle screw technique. Axial and sagittal CT reconstructed images along the axis of the inserted screws were evaluated for screw placements both in the medio-lateral and supero-inferior directions.

RESULTS

A total of 577 pedicle screw placements (C3 to C7) were assessed in 99 patients using the conventional grading of screw perforations and acceptable errors classification in both medio-lateral and supero-inferior directions. There were 25.64% (148/577) screw perforations and 74.35% (429/577) screw placements within the pedicle using the conventional perforation grading system. The same set of screws, assessed using the "Acceptable errors classification", showed 529 screws (91.68%) having acceptable placements and 48 screws (8.31%) having unacceptable placements.

CONCLUSION

The acceptable errors classification in placement of CPS seems to bridge the gap between the high radiological perforation rates and the low clinical complications. The present study reinforces studies reporting minimal clinical complications with high rates of screw misplacements. These slides can be retrieved under Electronic Supplementary Material.

A Ward-Round Non-Technical Skills for Surgery (WANTSS) Taxonomy

BACKGROUND

Around half of surgical adverse events occur outside the operating room. However the majority of nontechnical skills (NTS) training programs have been developed for the intraoperative environment. Ward rounds are a crucial part of extraoperative care and to date no specific NTS training manual has been developed targeting emergency general surgical ward rounds.

AIM

To develop a NTS taxonomy for emergency general surgical ward rounds that can be used to improve surgical team members' NTS and improve outcomes.

METHODS

A literature review of existing NTS taxonomies was conducted, followed by semistructured interviews and observational data collection, to determine good and poor surgical ward-round behaviors. These behaviors were reviewed by a panel of subject matter experts and categorized into a taxonomy, using the Non-Technical Skills for Surgeons taxonomy framework as a guide.

RESULTS

The Ward-round Non-Technical Skills for Surgery taxonomy includes examples of good and poor ward-round-specific behaviors, grouped into elements and categories. The taxonomy can be used as both a training and teaching manual for the surgical team.

CONCLUSION

Ward rounds are a crucial part of extraoperative surgical care. The Ward-round Non-Technical Skills for Surgery taxonomy provides surgical teams with a manual to help them improve their ward-round NTS.

Offline identification of surgical deviations in laparoscopic rectopexy

OBJECTIVE

According to a meta-analysis of 7 studies, the median number of patients with at least one adverse event during the surgery is 14.4%, and a third of those adverse events were preventable. The occurrence of adverse events forces surgeons to implement corrective strategies and, thus, deviate from the standard surgical process. Therefore, it is clear that the automatic identification of adverse events is a major challenge for patient safety. In this paper, we have proposed a method enabling us to identify such deviations. We have focused on identifying surgeons' deviations from standard surgical processes due to surgical events rather than anatomic specificities. This is particularly challenging, given the high variability in typical surgical procedure workflows.

METHODS

We have introduced a new approach designed to automatically detect and distinguish surgical process deviations based on multi-dimensional non-linear temporal scaling with a hidden semi-Markov model using manual annotation of surgical processes. The approach was then evaluated using cross-validation.

RESULTS

The best results have over 90% accuracy. Recall and precision for event deviations, i.e. related to adverse events, are respectively below 80% and 40%. To understand these results, we have provided a detailed analysis of the incorrectly-detected observations.

CONCLUSION

Multi-dimensional non-linear temporal scaling with a hidden semi-Markov model provides promising results for detecting deviations. Our error analysis of the incorrectly-detected observations offers different leads in order to further improve our method.

SIGNIFICANCE

Our method demonstrated the feasibility of automatically detecting surgical deviations that could be implemented for both skill analysis and developing situation awareness-based computer-assisted surgical systems.

Effect of Cognitive Aids on Adherence to Best Practice in the Treatment of Deteriorating Surgical Patients: A Randomized Clinical Trial in a Simulation Setting

Importance

Failure to rescue causes significant morbidity and mortality in the surgical population. Human error is often the underlying cause of failure to rescue. Human error can be reduced by the use of cognitive aids.

Objectives

To test the effectiveness of cognitive aids on adherence to best practice in the management of deteriorating postoperative surgical ward patients.

Design, Setting, and Participants

Randomized clinical trial in a simulation setting. Surgical teams consisted of 1 surgeon and 2 nurses from a surgical ward from 4 different hospitals in Amsterdam, the Netherlands. Data were analyzed between February 2, 2017, and December 18, 2018.

Interventions

The teams were randomized to manage 3 simulated deteriorating patient scenarios with or without the use of cognitive aids.

Main Outcomes and Measures

The primary outcome of the study was failure to adhere to best practice, expressed as the percentage of omitted critical management steps. The secondary outcome of the study was the perceived usability of the cognitive aids.

Results

Of the total participants, 93 were women and 51 were men. Twenty-five surgical teams performed 75 patient scenarios with cognitive aids, and 25 teams performed 75 patient scenarios without cognitive aids. Using the cognitive aids resulted in a reduction of omitted critical management steps from 33% to 10%, which is a 70% (P < .001) reduction. This effect remained significant (odds ratio, 0.63; 95% CI, -0.228 to -0.061; P = .001) in a multivariate analysis. Overall usability (scale of 0-10) of the cognitive aids was scored at a median of 8.7 (interquartile range, 8-9).

Conclusions and Relevance

Failure to comply with best practice management of postoperative complications is associated with worse outcomes. In this simulation study, adherence to best practice in the management of postoperative complications improves significantly by the use of cognitive aids. Cognitive aids for deteriorating surgical patients therefore have the potential to reduce failure to rescue and improve patient outcome.

Do 30-Day Reoperation Rates Adequately Measure Quality in Orthopedic Surgery?

BACKGROUND

Unplanned reoperation rates represent an important metric in monitoring quality in orthopedic surgery. Previous studies have focused on 30-day reoperation rates, not accounting for complications that may arise beyond this time. This study aimed to understand the frequency, timing, and procedure type of orthopedic reoperations, as well as the complications leading up to these reoperations over a 1-year period.

METHODS

A single-center, retrospective cohort study reviewed all orthopedic surgeries performed within a three-year period and subsequently identified reoperations within a year following the initial case. Exclusion criteria for reoperations included those that were planned, involved a different body part, or had a different laterality from the first operation. The cases were analyzed by procedure type, timing of reoperation, and causes of reoperation.

RESULTS

Of the 10,449 orthopedic surgeries performed between 2012 and 2015, 947 (9.1%) were unplanned reoperations within 1 year. Most (775; 81.8%) unplanned reoperations occurred after 30 days. Infections/wound complications (58.2%) were the most common reason for unplanned reoperations at 1 month from the initial operation, and mechanical complications (49.5%) predominated at the 6-months-to-1-year time frame.

CONCLUSION

This study demonstrated that the current paradigm of focusing on reoperations occurring within 30 days of the initial operation captures only a fraction of unplanned reoperations. Stratification of this metric by time and precipitating complication type provides additional information that quality improvement programs may target. A 1-year unplanned reoperation rate could be used as a broad indicator of surgical quality across institutions.

Gynecology healthcare professionals towards safety procedures in operation rooms aiming to enhanced quality of medical services in Greece

PURPOSE

The purpose of this paper is to investigate the attitudes of healthcare professionals in Greece toward safety practices in gynecological Operation Rooms (ORs).

DESIGN/METHODOLOGY/APPROACH

An anonymous self-administered questionnaire was distributed to surgical personnel asking for opinions on safety practices during vaginal deliveries (VDs) and gynecological operations (e.g. sponge/suture counting, counting documentation, etc.). The study took place in Hippokration Hospital of Thessaloniki including 227 participants. The team assessed and statistically analyzed the questionnaires.

FINDINGS

Attitude toward surgical counts and counting documentation, awareness of existence and/or implementation in their workplace of other surgical safety objectives (e.g. WHO safety control list) was assessed. In total, 85.2 percent considered that surgical counting after VDs is essential and 84.9 percent admitted doing so, while far less reported counting documentation as a common practice in their workplace and admitted doing so themselves (50.5/63.3 percent). Furthermore, while 86.5 percent considered a documented protocol as necessary, only 53.9 percent admitted its implementation in their workplace. Remarkably, 53.1 percent were unaware of the WHO safety control list for gynecological surgeries.

ORIGINALITY/VALUE

Most Greek healthcare professionals are well aware of the significance of surgical counting and counting documentation in gynecology ORs. However, specific tasks and assignments are unclear to them. Greek healthcare professionals consider surgical safety measures as important but there is a critical gap in knowledge when it comes to responsibilities and standardized processes during implementation. More effective implementation and increased personnel awareness of the surgical safety protocols and international guidelines are necessary for enhanced quality of surgical safety in Greece.

An Interdisciplinary Review of Surgical Data Recording Technology Features and Legal Considerations

Surgical data recording technology has great promise to generate patient safety and quality data that can be utilized to potentially reduce medical errors. Variations of these systems aim to improve surgical technique, develop better training simulation, and promote adverse event investigation similar to the aims of black box technology utilized in other industries. However, many unknowns remain for surgical data recording utilization in operating rooms and clinical settings in the United States. This includes the need to appropriately design systems so they collect meaningful and useful data that can be discussed by surgical team members in an open and safe environment to optimize clinical care processes. In order to better understand the clinical and regulatory environment for surgical data recording systems, we conducted an interdisciplinary review to identify key technology approaches, and assess legal and regulatory implications associated with this potentially disruptive technology. We found technology ranging from audio and visual data, to systems utilizing mobile applications, and kinematic data capture. The data collected present legal questions over ownership of information and privacy, along with regulatory issues at the federal and state levels. The benefits of these data should be balanced with the need to develop appropriate policies and regulations that protect the interests of both clinicians and patients in order to encourage further innovation and better realize the potential of surgical data recording technology to improve clinical decision making and patient safety outcomes.

Exploring the incidence and nature of nursing-sensitive orthopaedic adverse events: A multicenter cohort study using Global Trigger Tool

BACKGROUND

For decades, patient safety has been recognized as a critical global healthcare issue. However, there is a gap of knowledge of all types of adverse events sensitive to nursing care within hospitals in general and within orthopaedic care specifically.

OBJECTIVES

The aim of this study is to explore the incidence and nature of nursing-sensitive adverse events following elective or acute hip arthroplasty at a national level.

DESIGN

A retrospective multicenter cohort study.

OUTCOME VARIABLES

Nursing-sensitive adverse events, preventability, severity and length of stay.

METHODS

All patients, 18 years or older, who had undergone an elective (degenerative joint disease) or acute (fractures) hemi or total hip arthroplasty surgery at 24 hospitals were eligible for inclusion. Retrospective reviews of weighted samples of 1998 randomly selected patient records were carried out using the Swedish version of the Global Trigger Tool. The patients were followed for readmissions up to 90 days postoperatively throughout the whole country regardless of index hospital.

RESULTS

A total of 1150 nursing-sensitive adverse events were identified in 728 (36.4%) of patient records, and 943 (82.0%) of the adverse events were judged preventable in the study cohort. The adjusted cumulative incidence regarding nursing-sensitive adverse events for the study population was 18.8%. The most common nursing-sensitive adverse event types were different kinds of healthcare-associated infections (40.9%) and pressure ulcers (16.5%). Significantly higher proportions of nursing-sensitive adverse events were found among female patients compared to male, p < 0.001, and patients with acute admissions compared to elective patients, p < 0.001. Almost half (48.5%) of the adverse events were temporary and of a less severe nature. On the other hand, 592 adverse events were estimated to have contributed to 3351 extra hospital days.

CONCLUSIONS

This study shows the magnitude of nursing-sensitive adverse events. We found that nursing-sensitive adverse events were common, in most cases deemed preventable and were associated with different kinds of adverse events and levels of severity in orthopaedic care. Registered nurses play a vital role within the interdisciplinary team as they are the largest group of healthcare professionals, work 24/7 and spend much time at the bedside with patients. Therefore, nursing leadership at all hospital levels must assume responsibility for patient safety and authorize bedside registered nurses to deliver high-quality and sustainable care to patients.
