Incidence, Management, and Outcomes of Intraoperative Catastrophes During Robotic Pulmonary Resection.

BACKGROUND: Intraoperative catastrophes during robotic anatomical pulmonary resections are potentially devastating events. The present study aimed to assess the incidence, management, and outcomes of these intraoperative catastrophes for patients with primary lung cancers. METHODS: This was a retrospective, multiinstitutional study that evaluated patients who underwent robotic anatomical pulmonary resections. Intraoperative catastrophes were defined as events necessitating emergency thoracotomy or requiring an additional unplanned major surgical procedure. Standardized data forms were collected from each institution, with questions on intraoperative management strategies of catastrophic events. RESULTS: Overall, 1810 patients underwent robotic anatomical pulmonary resections, including 1566 (86.5%) lobectomies. Thirty-five patients (1.9%) experienced an intraoperative catastrophe. These patients were found to have significantly higher clinical TNM stage (P = .031) and lower forced expiratory volume in 1 second (81% vs 90%; P = .004). A higher proportion of patients who had a catastrophic event underwent preoperative radiotherapy (8.6% vs 2.3%; P = .048), and the surgical procedures performed differed significantly compared with noncatastrophic patients. Patients in the catastrophic group had higher perioperative mortality (5.7% vs 0.5%; P = .018), longer operative duration (195 minutes vs 170 minutes; P = .020), and higher estimated blood loss (225 mL vs 50 mL; P < .001). The most common catastrophic event was intraoperative hemorrhage from the pulmonary artery, followed by injury to the airway, pulmonary vein, and liver. Detailed management strategies were discussed. CONCLUSIONS: The incidence of catastrophic events during robotic anatomical pulmonary resections was low, and the most common complication was pulmonary arterial injury. Awareness of potential intraoperative catastrophes and their management strategies are critical to improving clinical outcomes.

Development and Pilot Testing of an Assessment Tool for Performance of Invasive Mediastinal Staging.

BACKGROUND: To develop and evaluate a surgical trainee competency assessment instrument for invasive mediastinal staging, including cervical mediastinoscopy and endobronchial ultrasound (EBUS), a comprehensive instrument was developed, the Thoracic Competency Assessment Tool-Invasive Staging (TCAT-IS), using expert review and simulated and clinical pilot-testing. METHODS: Validity and reliability evidence were collected, and item analysis was performed. Initially, a 27-item instrument was developed, which underwent expert review with members of the Canadian Association of Thoracic Surgeons (n = 86) in 2014 to 2015 (response rate, 57%). TCAT-IS was refined to 29 items in 4 competency areas: preoperative, general operative, mediastinoscopy, and EBUS. Further refinements were made based on simulated use. The final version was then used to assess competency of 5 thoracic trainees performing invasive mediastinal staging in live patients. RESULTS: Participants were assessed during 20 mediastinoscopy and 8 EBUS procedures, with 47 total assessments completed. Reliability (Cronbach's alpha = 0.94), interrater reliability (κ = 0.80), and correlation with an established global competency scale (κ = 0.75) were high. The most difficult items were "set up and adjust EBUS equipment" and "identify vascular anatomy (EBUS)." Feedback questionnaires from trainees (response rate, 80%) and surgeons (response rate, 100%) were consistently positive regarding user friendliness, utility as an assessment tool, and educational benefit. Participants believed the tool "facilitated communicating feedback to the trainee with specific areas to work on." CONCLUSIONS: TCAT-IS is an effective tool for assessing competence in invasive staging and may enhance instruction. This initial test establishes early validity and reliability evidence, supporting the use of TCAT-IS in providing structured, specific, formative assessments of competency.

The economic impact of a nurse practitioner-directed lung cancer screening, incidental pulmonary nodule, and tobacco-cessation clinic.

OBJECTIVE: Lung cancer screening programs have become increasingly prevalent within the United States after the National Lung Screening Trial results. We aimed to review the financial impact after programmatic implementation of Advanced Registered Nurse Practitioner-led programs of Lung Cancer Screening and Tobacco Related Diseases, Incidental Pulmonary Nodule Clinic, and Tobacco Cessation Services. METHODS: We reviewed revenue from 2013 to 2016 by our nurse practitioner-led program. Encounters were queried for charges related to outpatient evaluation and management, professional procedures, and facility charges related to both outpatient and inpatient procedures. Revenue was normalized using 2016 data tables and the national Medicare conversion factor (35.8043). RESULTS: Our program evaluated 694 individuals, of whom 75% (518/694) are enrolled within the lung cancer-screening program. Overall revenue associated with the programs was $733,336. Outpatient evaluation and management generated revenue of $168,372. In addition, professional procedure revenue accounted for an additional $60,015 with facility revenue adding an additional $504,949. CONCLUSIONS: A nurse practitioner-led program of lung cancer screening, incidental pulmonary nodules, and tobacco-cessation services can provide additional revenue opportunities for a Thoracic Surgery and Interventional Pulmonology Division, as well as a health care system. The current national, median annual wage of a nurse practitioner is $98,190, and the cost associated directly to their salary (and benefits) may remain neutral or negative within certain programs. However, the larger economic benefit may be realized within the division and institution. This potential additional revenue appears related to evaluation of newly identified diseases and subsequent evaluations, procedures, and operations.

Assessment and reduction of diaphragmatic tension during hiatal hernia repair.

BACKGROUND: During hiatal hernia repair there are two vectors of tension: axial and radial. An optimal repair minimizes the tension along these vectors. Radial tension is not easily recognized. There are no simple maneuvers like measuring length that facilitate assessment of radial tension. The aims of this project were to: (1) establish a simple intraoperative method to evaluate baseline tension of the diaphragmatic hiatal muscle closure; and, (2) assess if tension is reduced by relaxing maneuvers and if so, to what degree. METHODS: Diaphragmatic characteristics and tension were assessed during hiatal hernia repair with a tension gage. We compared tension measured after hiatal dissection and after relaxing maneuvers were performed. RESULTS: Sixty-four patients (29 M:35F) underwent laparoscopic hiatal hernia repair. Baseline hiatal width was 2.84 cm and tension 13.6 dag. There was a positive correlation between hiatal width and tension (r = 0.55) but the strength of association was low (r (2) = 0.31). Four different hiatal shapes (slit, teardrop, "D", and oval) were identified and appear to influence tension and the need for relaxing incision. Tension was reduced by 35.8 % after a left pleurotomy (12 patients); by 46.2 % after a right crural relaxing incision (15 patients); and by 56.1 % if both maneuvers were performed (6 patients). CONCLUSIONS: Tension on the diaphragmatic hiatus can be measured with a novel device. There was a limited correlation with width of the hiatal opening. Relaxing maneuvers such as a left pleurotomy or a right crural relaxing incision reduced tension. Longer term follow-up will determine whether outcomes are improved by quantifying and reducing radial tension.

Lung resection outcomes and costs in Washington State: a case for regional quality improvement.

BACKGROUND: A regional quality improvement effort does not exist for thoracic surgery in the United States. To initiate the development of one, we sought to describe temporal trends and hospital-level variability in associated outcomes and costs of pulmonary resection in Washington (WA) State. METHODS: A cohort study (2000-2011) was conducted of operated-on lung cancer patients. The WA State discharge database was used to describe outcomes and costs for operations performed at all nonfederal hospitals within the state. RESULTS: Over 12 years, 8,457 lung cancer patients underwent pulmonary resection across 49 hospitals. Inpatient deaths decreased over time (adjusted p-trend=0.023) but prolonged length of stay did not (adjusted p-trend=0.880). Inflation-adjusted hospital costs increased over time (adjusted p-trend<0.001). Among 24 hospitals performing at least 1 resection per year, 5 hospitals were statistical outliers in rates of death (4 lower and 1 higher than the state average), and 13 were outliers with respect to prolonged length of stay (7 higher and 6 lower than the state average) and costs (5 higher and 8 lower than the state average). When evaluated for rates of death and costs, there were hospitals with fewer deaths/lower costs, fewer deaths/higher costs, more deaths/lower costs, and more deaths/higher costs. CONCLUSIONS: Variability in outcomes and costs over time and across hospitals suggest opportunities to improve the quality and value of thoracic surgery in WA State. Examples from cardiac surgery suggest that a regional quality improvement collaborative is an effective way to meaningfully and rapidly act upon these opportunities.

Defining the cost of care for lobectomy and segmentectomy: a comparison of open, video-assisted thoracoscopic, and robotic approaches.

BACKGROUND: Knowledge about the cost of open, video-assisted thoracoscopic (VATS), or robotic lung resection and drivers of cost is crucial as the cost of care comes under scrutiny. This study aims to define the cost of anatomic lung resection and evaluate potential cost-saving measures. METHODS: A retrospective review of patients who had anatomic resection for early stage lung cancer, carcinoid, or metastatic foci between 2008 and 2012 was performed. Direct hospital cost data were collected from 10 categories. Capital depreciation was separated for the robotic and VATS cases. Key costs were varied in a sensitivity analysis. RESULTS: In all, 184 consecutive patients were included: 69 open, 57 robotic, and 58 VATS. Comorbidities and complication rates were similar. Operative time was statistically different among the three modalities, but length of stay was not. There was no statistically significant difference in overall cost between VATS and open cases (Δ = $1,207) or open and robotic cases (Δ = $1,975). Robotic cases cost $3,182 more than VATS (p < 0.001) owing to the cost of robotic-specific supplies and depreciation. The main opportunities to reduce cost in open cases were the intensive care unit, respiratory therapy, and laboratories. Lowering operating time and supply costs were targets for VATS and robotic cases. CONCLUSIONS: VATS is the least expensive surgical approach. Robotic cases must be shorter in operative time or reduce supply costs, or both, to be competitive. Lessening operating time, eradicating unnecessary laboratory work, and minimizing intensive care unit stays will help decrease direct hospital costs.

2004 MacLean-Mueller prize enteral or parenteral nutrition for severe pancreatitis: a randomized controlled trial and health technology assessment.

BACKGROUND: The optimal route of nutrition in severe pancreatitis is controversial. Parenteral nutrition (PN) is preferred, but enteral nutrition (EN) promises to attenuate inflammation and prevent sepsis. We hypothesized that EN was at least equivalent to PN in reducing inflammation, providing effective nutrition and being cost-effective. METHODS: We conducted a randomized controlled trial comparing PN to EN in pancreatitis in an academic, multi-institutional, tertiary care health system. We screened 728 consecutive patients. Twenty-eight patients with a Ranson's score greater than 2 who did not tolerate clear fluids 4 days after admission were randomized: 18 to PN and 10 to EN. Both groups were provided daily 105 kJ (25 kcal)/kg and 1.5 g/kg of protein, respectively, until they could tolerate a regular diet. RESULTS: C-reactive protein in EN patients was reduced by 50% 5 days faster than PN patients (Wilcoxon test, p = 0.09). Both groups received a similar number of kilojoules and achieved near normal prealbumin and 24-hour urinary nitrogen values. Neither regimen caused a change in cholecystokinin levels. Overall mortality was 4.9% (3 patients in the PN group). In 5 patients (4 PN, 1 EN) there were infected pancreatic collections. Nine EN patients dislodged the nasojejunal tube. EN had an average cost of dollar 1375 per patient compared with dollar 2608 for PN (p = 0.08). After sensitivity analysis, EN cost dollar 957 compared with dollar 2608 for PN (p = 0.03). CONCLUSIONS: EN or PN is safe and provides adequate nutrition in severe pancreatitis. EN shows a trend toward faster attenuation of inflammation, with fewer septic complications and is the dominant therapy in terms of cost-effectiveness. This study favours EN for nutritional support in severe pancreatitis.
