Ex vivo lung perfusion in donation after circulatory death: A post hoc analysis of the Normothermic Ex Vivo Lung Perfusion as an Assessment of Extended/Marginal Donors Lungs trial.

OBJECTIVE: Donation after circulatory death (DCD) donors offer the ability to expand the lung donor pool and ex vivo lung perfusion (EVLP) further contributes to this ability by allowing for additional evaluation and resuscitation of these extended criteria donors. We sought to determine the outcomes of recipients receiving organs from DCD EVLP donors in a multicenter setting. METHODS: This was an unplanned post hoc analysis of a multicenter, prospective, nonrandomized trial that took place during 2011 to 2017 with 3 years of follow-up. Patients were placed into 3 groups based off procurement strategy: brain-dead donor (control), brain-dead donor evaluated by EVLP, and DCD donors evaluated by EVLP. The primary outcomes were severe primary graft dysfunction at 72 hours and survival. Secondary outcomes included select perioperative outcomes, and 1-year and 3-years allograft function and quality of life measures. RESULTS: The DCD EVLP group had significantly higher incidence of severe primary graft dysfunction at 72 hours (P = .03), longer days on mechanical ventilation (P < .001) and in-hospital length of stay (P = .045). Survival at 3 years was 76.5% (95% CI, 69.2%-84.7%) for the control group, 68.3% (95% CI, 58.9%-79.1%) for the brain-dead donor group, and 60.7% (95% CI, 45.1%-81.8%) for the DCD group (P = .36). At 3-year follow-up, presence observed bronchiolitis obliterans syndrome or quality of life metrics did not differ among the groups. CONCLUSIONS: Although DCD EVLP allografts might not be appropriate to transplant in every candidate recipient, the expansion of their use might afford recipients stagnant on the waitlist a viable therapy.

Venous Thromboembolism in Patients Hospitalized for Lung Transplantation.

BACKGROUND: Venous thromboembolism (VTE) is an important complication after solid organ transplantation. We sought to evaluate any association between VTE and in-hospital death, length of hospitalization, and total hospital charges for patients hospitalized for lung transplantation (LT). METHODS: We retrospectively reviewed the Nationwide Inpatient Sample to identify patients hospitalized for LT from 2000 to 2011. We evaluated the incidence of VTE during hospitalization for LT, risk factors for VTE, and the association between VTE and in-hospital death, length of hospitalization, and total hospital charges. RESULTS: Of the 16,318 adults hospitalized for LT during the study period, VTE developed in 1,029 (6.3%), including 854 (5.4%) with deep vein thrombosis alone and 175 (1.1%) with pulmonary embolism. The factors associated with VTE included age older than 60 years (odds ratio [OR], 1.42; 95% confidence interval [CI], 1.03 to 1.94), female sex (OR, 0.61; 95% CI, 0.44 to 0.86), and receiving mechanical ventilation support for 96 hours or more (OR, 3.38; 95% CI, 2.49 to 4.58). The adjusted odds of in-hospital death in patients with pulmonary embolism was thrice as high as those without any VTE (OR, 3.40; 95% CI, 1.29 to 8.99). Among LT patients with VTE, the average length of hospitalization was 38% (95% CI, 27% to 48%) longer, and the total cost of hospitalization was 23% (95% CI, 16% to 30%) higher compared with LT patients without VTE. CONCLUSIONS: VTE is a relatively frequent complication among LT recipients and is associated with increased death, total hospital length of stay, and hospital charges. These data indicate that prophylaxis practices should be reexamined to reduce this preventable complication.

ECMO Support in Lung Transplantation: A Contemporary Analysis of Hospital Charges in the United States.

BACKGROUND: There is little in the literature pertaining to cost associated with the use of extracorporeal membrane oxygenation (ECMO) in lung transplantation. We sought to evaluate charges associated with the index hospitalization among recipients of a lung transplant who required ECMO to identify factors that increase hospital charges in these patients. METHODS: With the use of the Nationwide Inpatient Sample, we reviewed data pertaining to patients who received a lung transplant between 2000 and 2011 and stratified them into ECMO and non-ECMO groups based on use of ECMO. Regression modeling was used to identify differences in charges. RESULTS: Data pertaining to 15,596 recipients of a lung transplant were evaluated, 658 (4.2%) of whom required ECMO. ECMO recipients were more likely to have a diagnosis of idiopathic pulmonary fibrosis (3.5% versus 1.3%, p = 0.007) or pulmonary hypertension (PH) (9.1% versus 3.0%, p < 0.001). Patients who received a bilateral lung transplant had 32.1% (95% confidence interval [CI]: 26.2% to 37.9%, p < 0.001) higher charges. Recipients with PH had 28.7% (95% CI: 14.9% to 42.4%, p = 0.001) higher charges. Median charges for recipients of a lung transplant who required ECMO were $780,391.50 versus $324,279.80 for non-ECMO recipients of a lung transplant and were 50.3% (95% CI: 33.0% to 67.5%, p < 0.001) higher. Hospital charges among Medicare enrollees were 6.6% (95% CI: 0.7% to 12.5%, p = 0.028) higher than privately insured recipients of a lung transplant. Black recipients had approximately 34.2% (95% CI: 3.2% to 65.0%, p = 0.030) higher charges. The ECMO group had longer median length of stay (LOS) (25 versus 15 days, p < 0.001). CONCLUSIONS: Recipients of a lung transplant who required ECMO support had longer LOS and higher hospital charges, specifically among black recipients, recipients with PH, and Medicare enrollees.

Postoperative Swallowing Assessment After Lung Transplantation.

BACKGROUND: Dysphagia, aspiration, and potential pneumonia represent a major source of morbidity in patients undergoing lung transplantation. Conditions that potentiate dysphagia and aspiration include frailty and prolonged intubation. Our group of speech-language pathologists has been actively involved in performance of a bedside evaluation of swallowing, and instrumental evaluation of swallowing with modified barium swallow, and postoperative management in patients undergoing lung transplantation. METHODS: All lung transplant patients from April 2009 to September 2012 were evaluated retrospectively. A clinical bedside examination was performed by the speech-language pathology team, followed by a modified barium swallow or fiberoptic endoscopic evaluation of swallowing. RESULTS: A total of 321 patients were referred for evaluation. Twenty-four patients were unable to complete the evaluation. Clinical signs of aspiration were apparent in 160 patients (54%). Deep laryngeal penetration or aspiration were identified in 198 (67%) patients during instrumental testing. A group of 81 patients (27%) had an entirely normal clinical examination, but were found to have either deep penetration or aspiration. CONCLUSIONS: The majority of patients aspirate after lung transplantation. Clinical bedside examination is not sensitive enough and will fail to identify patients with silent aspiration. A standard of practice following lung transplantation has been established that helps avoid postoperative aspiration associated with complications.

Effect of insurance status on the surgical treatment of early-stage non-small cell lung cancer.

BACKGROUND: Social disparities permeate non-small cell lung cancer (NSCLC) treatment, yet little is known about the effect of insurance status on the delivery of guideline surgical treatment for early-stage (I or II) NSCLC. METHODS: We used the California Cancer Registry (1996 through 2008) to identify patients 50 to 94 years old with early-stage NSCLC. We used logistic regression models to assess whether or not insurance status (private insurance, Medicare, Medicaid, no insurance, and unknown) had an effect on whether or not a lobectomy (or bilobectomy) is performed. RESULTS: A total of 10,854 patients met our inclusion criteria. Compared with patients with private insurance, we found that patients with Medicare (adjusted odds ratio [aOR] 0.87; 95% confidence interval [CI]: 0.79 to 0.95), Medicaid (aOR 0.45; 95% CI: 0.36 to 0.57), or no insurance (aOR 0.45; 95% CI: 0.29 to 0.70) were significantly less likely to undergo lobectomy, even after adjusting for patient factors (age, race, and gender) and tumor characteristics (histology and tumor size). Increasing age, African American race, squamous cell carcinoma, and increasing tumor size were significant independent negative predictors of whether or not a lobectomy was performed. CONCLUSIONS: Patients without private insurance were significantly less likely than patients with private insurance to undergo a lobectomy for early-stage NSCLC. The variables(s) contributing to this disparity have yet to be elucidated.

A multi-institutional survey of newer surgery faculty on the impacts of education debt and debt repayment strategies.

BACKGROUND: The cost associated with becoming a physician is significant, and studies have shown that surgeons, in particular, accrue higher debts than matched controls from other specialties, and the public. These findings, along with the current era of economic turmoil, prompted our investigation into the effects of educational debt on the career, family and lifestyle choices of recently graduated surgeons. Our goal was to query young surgical faculty about the education debt carried, the burden it presents as they embark on a career, and the financial management strategies employed to pay down their debt. STUDY DESIGN: This study is a one-time, cross-sectional survey of regular and adjunct faculty from the University of Minnesota and the Mayo Clinic-Rochester. Participation was voluntary and responses were collected anonymously via SurveyMonkey. Respondents were sorted into two groups: those with and without education debt at the time of residency graduation. We compared these groups on a number of variables. RESULTS: Of the 111 respondents (111/152, 73% response rate), 69 (62.2%) carried debt at the time of graduation from residency. The median educational debt at graduation was $100,000, and surgeons with educational debt carried a significantly higher burden of consumer and total debt than those without educational debt at graduation (p < 0.001). This continued after graduation with 74% (51/69) of residents with debt at graduation falling below the benchmark 36% debt-to-income ratio, and 45% (17/32) of those without debt at graduation in this same high risk financial situation. CONCLUSIONS: Educational debt places a large financial responsibility on the shoulders of most newer faculty. The debt-to-income ratio demonstrated through our results was considerable for both study groups, and unwise according to financial literature. This is of utmost importance to leaders in academe, as salaries are generally lower than private practice colleagues. This can begin in residency with explicit and practical information on surgeon reimbursement, income ranges, and revenue sources (faculty, clinical), debt repayment strategies, and overall training on financial matters early in their residency.

Comparing apples to apples: a call for unification of complication reporting across health systems.

The formalization of assessment of surgical outcomes across health care systems for complex procedures is a significant problem in the surgical literature. Low and colleagues present support for the use of the Accordion Severity Grading System as a tool to provide simple and comprehensive assessment of postoperative complications.

Primary palmoplantar hyperhidrosis and thoracoscopic sympathectomy: a new objective assessment method.

BACKGROUND: This study was conducted to establish an objective approach to evaluate symptoms and sweat production in patients with primary palmoplantar hyperhidrosis (PPH) and assess their response to bilateral thoracoscopic sympathectomy (BTS). METHODS: We conducted two institutional review board-approved studies. We performed a one-time evaluation of healthy volunteers (controls) with three questionnaires (Hyperhidrosis Disease Severity Scale, Dermatology Life Quality Index, and Short Form-36) and measurement of transepidermal water loss (TEWL; g/m(2)/h). We evaluated PPH patients with these same tools before and 1 month after BTS and compared them with controls. RESULTS: We evaluated 35 controls (mean age, 23.0 +/- 3.3 years) and 45 PPH patients (mean age, 26.5 +/- 12.3 years); 18 PPH patients underwent BTS and the 1-month postoperative evaluation. Hyperhidrosis Disease Severity Scale and Dermatology Life Quality Index scores were higher in PPH patients than in controls (p < 0.0001), but normalized after BTS. Short Form-36 scale scores were lower in PPH patients than in controls (p < 0.05), but improved significantly after BTS. Compared with controls, preoperative TEWL values were significantly higher in PPH patients (palmar: 142.7 +/- 43.6 PPH vs 115.8 +/- 48.7 controls, p = 0.011; plantar: 87.5 +/- 28.8 PPH vs 57.7 +/- 24.7 controls, p < 0.0001). After BTS, palmar TEWL values were significantly lower (49.1 +/- 29.8, p < 0.0001). Plantar TEWL did not change significantly (77.6 +/- 46.6, p = 0.52). CONCLUSIONS: PPH patients should be objectively evaluated with standardized quality of life measures and TEWL measurements before and after treatment. We believe that this objective practical approach provides a benchmark for clinical practice and research.
