Organization of thoracic surgical services during the COVID pandemic.

INTRODUCTION: COVID-19 presented an unprecedented challenge for healthcare workers and systems around the world. Healthcare systems have adapted differently in terms of pandemic planning of regular services, adopting infection control measures and prioritising essential hospital services in the context of a burgeoning COVID-19 patient load and inevitable surge. METHODS: We performed a review on current evidence and share our practices at a teaching hospital in Singapore. RESULTS: We outline principles and make recommendations for continuity of delivering essential thoracic surgical services during this current outbreak. CONCLUSIONS: The maintenance and provision of thoracic surgery services in this context requires good preplanning and vigilance to infection control measures across all levels.

Anesthesia for Patients Undergoing Anesthesia for Elective Thoracic Surgery During the COVID-19 Pandemic: A Consensus Statement From the Israeli Society of Anesthesiologists.

Anesthesia for thoracic surgery requires specialist intervention to provide adequate operating conditions and one-lung ventilation. The pandemic caused by severe acute respiratory syndrome-associated coronavirus 2 (SARS-CoV-2) is transmitted by aerosol and droplet spread. Because of its virulence, there is a risk of transmission to healthcare workers if appropriate preventive measures are not taken. Coronavirus disease 2019 (COVID-19) patients may show no clinical signs at the early stages of the disease or even remain asymptomatic for the whole course of the disease. Despite the lack of symptoms, they may be able to transfer the virus. Unfortunately, during current COVID-19 testing procedures, about 30% of tests are associated with a false-negative result. For these reasons, standard practice is to assume all patients are COVID-19 positive regardless of swab results. Here, the authors present the recommendations produced by the Israeli Society of Anesthesiologists for use in thoracic anesthesia for elective surgery during the COVID-19 pandemic for both the general population and COVID-19-confirmed patients. The objective of these recommendations is to make changes to some routine techniques in thoracic anesthesia to augment patients' and the medical staff's safety.

Resident perception of standardization and credentialing for high-risk bedside procedures in cardiothoracic surgery: Results from an institutional pilot study.

OBJECTIVES: Though clear-guidelines are set by the American Board of Thoracic Surgery (ABTS) for the operative cases that cardiothoracic surgery residents must perform to be board-eligible, no such recommendations exist to assess competency for the wide range of high-risk bedside procedures. Our department created and implemented a multidisciplinary course designed to standardize common high-risk bedside procedures and credential our trainees. The aim of this study was to survey the attitudes of residents towards and query the efficacy of such a course. METHODS: The course was designed with the goal of standardizing endotracheal intubation, arterial line insertion (radial and femoral), central venous line insertion, pigtail tube thoracostomy, thoracentesis and nasogastric tube placement. The course consisted of an online module followed by a 4-hour hands-on simulation session. Knowledge-based pre- and post-evaluations were administered as well as a Likert-based survey regarding multiple aspects of the residents' perceptions of the course and the procedures. RESULTS: Twenty-three (7 traditional and 16 integrated) cardiothoracic surgical residents participated in the course. Residents reported that 48% of the time, bedside procedures were historically taught by other trainees rather than by faculty. All residents endorsed increased standardization of all procedures after the course. Likewise, residents showed increased confidence in all procedures except for pigtail tube thoracostomy, thoracentesis as well as nasogastric tube placement. 43.5% of the participants demonstrated improvement in the pretest and posttest knowledge-based evaluations. CONCLUSION: Cardiothoracic residents have favorable attitudes towards standardization and credentialing for high-risk bedside procedures and utilizing such courses may help standardize procedural techniques.

Frailty assessment prior to thoracic surgery for lung or esophageal cancer: a feasibility study.

BACKGROUND: Frailty assessment has not been thoroughly assessed in thoracic surgery. Our primary objective was to assess the feasibility of comprehensive frailty testing prior to lung and esophageal surgery for cancer. The secondary objective was to assess the utility of frailty indices in risk assessment prior to thoracic surgery. METHODS: Prospectively recruited patients completed multiple physiotherapy tests (6-min walk, gait speed, hand-grip strength), risk stratification (Charlson Comorbidity Index, Revised Cardiac Risk Index, Modified Frailty Index), and quality of life questionnaires. Lean psoas area was also assessed by a radiologist using positron emission tomography/computed tomography scans. Data was analyzed using Fisher's exact, Mann-Whitney U and independent t tests. RESULTS: The feasibility of comprehensive frailty assessment was assessed over a 4-month period among 40 patients (esophagus n = 20; lung n = 20). Risk stratification questionnaires administered in clinic had 100% completion rates. Physiotherapy testing required a trained physiotherapist and an additional visit to the pre-admission clinic; these tests proved difficult to coordinate and had lower completion rates (63-75%). Although most measures were not significantly associated with occurrence of complications, the Modified Frailty Index approached statistical significance (p = 0.06). CONCLUSIONS: Frailty assessment is feasible in the pre-operative outpatient setting and had a high degree of acceptance among surgeons and patients. Of the risk stratification questionnaires, the Modified Frailty Index may be useful in predicting outcomes as per this feasibility study. Pre-operative frailty assessment can identify vulnerable oncology patients to aid in treatment planning with the goal of optimizing clinical outcomes and resource allocation.

Pan-Canadian standards for cancer surgery

About the Canadian Partnership Against Cancer: The Canadian Partnership Against Cancer (CPAC) is an independent organization funded by the federal government to accelerate action on cancer control for all Canadians. As the steward of the Canadian Strategy for Cancer Control (the Strategy), the Partnership works with Canada's cancer community to take action to ensure fewer people get cancer, more people survive cancer and those living with the disease have a better quality of life. This work is guided by the Strategy, which was refreshed for 2019 to 2029, and will help drive measurable change for all Canadians affected by cancer. The Strategy includes 5 priorities that will tackle the most pressing challenges in cancer control as well as distinct First Nations, Inuit and Métis Peoples­specific priorities and actions reflecting Canada's commitment to reconciliation. A specific action in the Strategy calls for reducing the differences in practice and service delivery by setting standards for high-quality care and promoting their adoption. The CPAC will oversee the implementation of the priorities in collaboration with organizations and individuals on the front lines of cancer care: the provinces and territories; health care professionals; people living with cancer and those who care for them; First Nations, Inuit and Métis communities; governments and organizations; and its funder, Health Canada.

The Australian and New Zealand Society of Cardiac and Thoracic Surgeons Database Program - Two Decades of Quality Assurance Data.

Over two decades, the Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) cardiac surgery database program has evolved from a single state-based database to a national clinical quality registry program and is now the most comprehensive cardiac surgical registry in Australia. We report the current structure and governance of the program and its key activities.

The Society of Thoracic Surgeons, The Society of Cardiovascular Anesthesiologists, and The American Society of ExtraCorporeal Technology: Clinical Practice Guidelines-Anticoagulation During Cardiopulmonary Bypass.

Despite more than a half century of "safe" cardiopulmonary bypass (CPB), the evidence base surrounding the conduct of anticoagulation therapy for CPB has not been organized into a succinct guideline. For this and other reasons, there is enormous practice variability relating to the use and dosing of heparin, monitoring heparin anticoagulation, reversal of anticoagulation, and the use of alternative anticoagulants. To address this and other gaps, The Society of Thoracic Surgeons, the Society of Cardiovascular Anesthesiologists, and the American Society of Extracorporeal Technology developed an Evidence Based Workgroup. This was a group of interdisciplinary professionals gathered to summarize the evidence and create practice recommendations for various aspects of CPB. To date, anticoagulation practices in CPB have not been standardized in accordance with the evidence base. This clinical practice guideline was written with the intent to fill the evidence gap and to establish best practices in anticoagulation therapy for CPB using the available evidence. To identify relevant evidence, a systematic review was outlined and literature searches were conducted in PubMed using standardized medical subject heading (MeSH) terms from the National Library of Medicine list of search terms. Search dates were inclusive of January 2000 to December 2015. The search yielded 833 abstracts, which were reviewed by two independent reviewers. Once accepted into the full manuscript review stage, two members of the writing group evaluated each of 286 full papers for inclusion eligibility into the guideline document. Ninety-six manuscripts were included in the final review. In addition, 17 manuscripts published before 2000 were included to provide method, context, or additional supporting evidence for the recommendations as these papers were considered sentinel publications. Members of the writing group wrote and developed recommendations based on review of the articles obtained and achieved more than two thirds agreement on each recommendation. The quality of information for a given recommendation allowed assessment of the level of evidence as recommended by the American College of Cardiology Foundation/American Heart Association Task Force on Practice Guidelines. Recommendations were written in the three following areas: (1) heparin dosing and monitoring for initiation and maintenance of CPB; (2) heparin contraindications and heparin alternatives; and (3) reversal of anticoagulation during cardiac operations. It is hoped that this guideline will serve as a resource and will stimulate investigators to conduct more research and to expand on the evidence base on the topic of anticoagulation therapy for CPB.

Comparison Between Pressure-Regulated Volume-Controlled and Volume-Controlled Ventilation on Oxygenation Parameters, Airway Pressures, and Immune Modulation During Thoracic Surgery.

OBJECTIVES: To compare 2 different ventilatory strategies: pressure-regulated volume-controlled (PRVC) versus volume-controlled ventilation during thoracotomy. DESIGN: Prospective randomized study. SETTING: University hospital. PARTICIPANTS: The study comprised 70 adult patients undergoing thoracic surgery. INTERVENTIONS: Evaluation of oxygenation parameters, airway pressures, and immune modulation. MEASUREMENTS AND MAIN RESULTS: The primary outcome was arterial oxygen tension/fraction of inspired oxygen (PaO2/FIO2) ratio, whereas secondary outcomes included arterial and central venous blood gases, deadspace volume/tidal volume ratio, peak inspiratory pressure, mean inspiratory pressure, and plateau inspiratory pressure obtained at the following 4 time points: 20 minutes after total lung ventilation (T0), 20 minutes after 1-lung ventilation (T1), 20 minutes after return to total lung ventilation (T2), and at the end of surgery (T3). Furthermore, alveolar and plasma levels of interleukin-8 and tumor necrosis factor-α and changes in alveolar albumin levels and cell numbers were measured at the same time points. Oxygenation parameters (PaO2/FIO2 and PaO2) were significantly better in the PRVC group (PaO2/FIO2 ratio at T1 was 176 v 146 in the PRVC and volume-controlled groups, respectively, with a p value of 0.004). Deadspace volume/tidal volume ratio and inspiratory airway pressures were significantly lower in the PRVC group. Furthermore, all inflammatory parameters (alveolar and plasma interleukins, alveolar albumin levels, and cell numbers) were significantly lower in the PRVC group. CONCLUSIONS: The PRVC mode during 1-lung ventilation in thoracic surgery caused a favorable effect on oxygenation parameters, respiratory mechanics, and immune modulation during thoracic surgery.

Perioperative diabetes care: room for improving the person centredness.

AIMS: Person centredness is an important principle for delivering high-quality diabetes care. In this study, we assess the level of person centredness of current perioperative diabetes care. METHODS: We conducted a survey in six Dutch hospitals, among 690 participants with diabetes who underwent major abdominal, cardiac or large-joint orthopaedic surgery. The survey included questions regarding seven dimensions of person-centred perioperative diabetes care. RESULTS: Complete data were obtained from 298 participants. The survey scores were low for many of the dimensions of person centredness. The dimensions 'information', 'patient involvement' and 'coordination and integration of care' had the lowest scores. Only half the participants had received information about perioperative diabetes treatment, and approximately one-third had received information about the effect of surgery on blood glucose values, target glucose values and glucose measurement times. Similarly, half the participants had an opportunity to ask questions preoperatively, and only one-third of the participants felt involved in the decision-making regarding diabetes treatment. Most participants knew neither the caregiver in charge of perioperative diabetes treatment nor whom to contact in case of diabetes-related problems during their hospital stay. CONCLUSIONS: Current perioperative diabetes care is characterized by a lack of patient information and limited patient involvement. These results indicate that there is ample room for improving the person centredness of perioperative diabetes care.

Benchmarking clinical practice in surgery: looking beyond traditional mortality rates.

This paper proposes two new measures to assess performance of surgical practice based on observed mortality: reliability, measured as the area under the ROC curve and a living score, the sum of individual risk among surviving patients, divided by the total number of patients. A Monte Carlo simulation of surgeons' practice was used for conceptual validation and an analysis of a real-world hospital department was used for managerial validation. We modelled surgical practice as a bivariate distribution function of risk and final state. We sampled 250 distributions, varying the maximum risk each surgeon faced, the distribution of risk among dead patients, the mortality rate and the number of surgeries performed yearly. We applied the measures developed to a Portuguese cardiothoracic department. We found that the joint use of the reliability and living score measures overcomes the limitations of risk adjusted mortality rates, as it enables a different valuation of deaths, according to their risk levels. Reliability favours surgeons with casualties, predominantly, in high values of risk and penalizes surgeons with deaths in relatively low levels of risk. The living score is positively influenced by the maximum risk for which a surgeon yields surviving patients. These measures enable a deeper understanding of surgical practice and, as risk adjusted mortality rates, they rely only on mortality and risk scores data. The case study revealed that the performance of the department analysed could be improved with enhanced policies of risk management, involving the assignment of surgeries based on surgeon's reliability and living score.

The Society of Thoracic Surgeons, The Society of Cardiovascular Anesthesiologists, and The American Society of ExtraCorporeal Technology: Clinical Practice Guidelines for Cardiopulmonary Bypass--Temperature Management During Cardiopulmonary Bypass.

UNLABELLED: In order to improve our understanding of the evidence-based literature supporting temperature management during adult cardiopulmonary bypass, The Society of Thoracic Surgeons, the Society of Cardiovascular Anesthesiology and the American Society of ExtraCorporeal Technology tasked the authors to conduct a review of the peer-reviewed literature, including: 1) optimal site for temperature monitoring, 2) avoidance of hyperthermia, 3) peak cooling temperature gradient and cooling rate, and 4) peak warming temperature gradient and rewarming rate. Authors adopted the American College of Cardiology/American Heart Association method for development clinical practice guidelines, and arrived at the following recommendations: CLASS I RECOMMENDATIONS: a)The oxygenator arterial outlet blood temperature is recommended to be utilized as a surrogate for cerebral temperature measurement during CPB. (Class I, Level C) b)To monitor cerebral perfusate temperature during warming, it should be assumed that the oxygenator arterial outlet blood temperature under-estimates cerebral perfusate temperature. (Class I, Level C) c)Surgical teams should limit arterial outlet blood temperature to<37°C to avoid cerebral hyperthermia. (Class 1, Level C) d)Temperature gradients between the arterial outlet and venous inflow on the oxygenator during CPB cooling should not exceed 10°C to avoid generation of gaseous emboli. (Class 1, Level C) e)Temperature gradients between the arterial outlet and venous inflow on the oxygenator during CPB rewarming should not exceed 10°C to avoid out-gassing when blood is returned to the patient. (Class 1, Level C) CLASS IIa RECOMMENDATIONS: a)Pulmonary artery or nasopharyngeal temperature recording is reasonable for weaning and immediate post-bypass temperature measurement. (Class IIa, Level C)b)Rewarming when arterial blood outlet temperature ≥30° C: i.To achieve the desired temperature for separation from bypass, it is reasonable to maintain a temperature gradient between arterial outlet temperature and the venous inflow of≤4°C. (Class IIa, Level B) ii.To achieve the desired temperature for separation from bypass, it is reasonable to maintain a rewarming rate≤0.5°C/min. (Class IIa, Level B) NO RECOMMENDATION: No recommendation for a guideline is provided concerning optimal temperature for weaning from CPB due to insufficient published evidence.

Efforts to improve the billing accuracy of robotic-assisted thoracic surgery through education, updated procedure cards, and electronic medical record system changes.

Precise medical billing is essential for decreasing hospital liability, upholding environmental stewardship and ensuring fair costs for patients. We instituted a multifaceted approach to improve the billing accuracy of our robotic-assisted thoracic surgery programme by including an educational component, updating procedure cards and removing the auto-populating function of our electronic medical record. Overall, we saw significant improvements in both the number of inaccurate billing cases and, specifically, the number of cases that overcharged patients.
