Health care and socioeconomic impact of falls in the elderly

BACKGROUND Elderly falls are associated with long hospital stays, major morbidity, and mortality. We sought to examine the fate of patients ≥75 years of age admitted after falls. METHODS We reviewed all fall admissions in 2008. Causes, comorbidities, injuries, procedures, mortality, readmission, and costs were analyzed. RESULTS Seven hundred eight patients ≥75 years old were admitted after a fall, with 89% being simple falls. Short-term mortality was 6%. Male sex, atrial fibrillation, acute myocardial infarction, congestive heart failure (CHF), intracranial hemorrhage, hospital-acquired pneumonia, trigger events, Clostridium difficile, and intubation were predictors of death (P < .05). Thirty-day readmission occurred in 14%; CHF, craniotomy, and acute renal failure were predictive. The median cost of hospitalization was

Central Airway Stabilization for Tracheobronchomalacia Improves Quality of Life in Patients With COPD

11,000 with cardiac disease, anemia, major orthopedic and neurosurgical procedures, pneumonia, and intubation as predictive. CONCLUSIONS Simple falls in the elderly have high morbidity, mortality, and costs. Methodologies for prevention are warranted and should be studied intensively.

Airway Stenting and Tracheobronchoplasty Improve Respiratory Symptoms in Mounier-Kuhn Syndrome

BACKGROUND Tracheobronchomalacia (TBM) is characterized by excessive collapsibility of the central airways, typically during expiration. TBM may be present in as many as 50% of patients evaluated for COPD. The impact of central airway stabilization on symptom pattern and quality of life is poorly understood in this patient population. METHODS Patients with documented COPD were identified from a cohort of 238 patients assessed for TBM at our complex airway referral center. Pulmonary function testing, exercise tolerance, and health-related quality-of-life (HRQOL) measures were assessed at baseline and 2 to 4 weeks following tracheal stent placement/operative tracheobronchoplasty (TBP). Severity of COPD was classified according to the GOLD (Global Initiative for Chronic Obstructive Lung Disease) staging system. RESULTS One hundred three patients (48 women) with COPD and moderately severe to severe TBM were identified. Statistically and clinically significant improvements were seen in HRQOL measures, including the transitional dyspnea index (stent, P = .001; TBP, P = .008), the St. George Respiratory Questionnaire (stent, P = .002; TBP, P < .0001), and the Karnofsky performance score (stent, P = .163; TBP, P < .0001). The improvement appeared greatest following TBP and was seen in all GOLD stages. Clinical improvement was also seen in measured FEV(1) and exercise capacity as assessed by 6-min walk test. CONCLUSIONS Central airway stabilization may provide symptomatic benefit for patients with severe COPD and concomitant severe airway malacia. Operative airway stabilization appears to impart the greatest advantage. Long-term follow-up study is needed to fully ascertain the ultimate efficacy of both stenting and surgical airway stabilization in this patient group.

Are There Gaps in Current Thoracic Surgery Residency Training Programs

BACKGROUND Mounier-Kuhn syndrome (MKS) is a condition characterized by tracheobronchomegaly resulting from the loss or atrophy of musculoelastic fibers within the airway wall. Concomitant tracheobronchomalacia is seen in most patients with MKS, often leading to significant respiratory compromise due to bronchiectasis, increased dead space, and impaired secretion clearance. METHODS We report a series of 12 patients with MKS and tracheobronchomalacia who were evaluated at our institution for significant respiratory problems. Stent trials were conducted in 10 patients, with seven proceeding to operative tracheobronchoplasty (TBP) and one continuing with long-term stent placement. One patient underwent TBP without prior stent placement. Of the remaining three patients, two had no improvement with trials of stent placement, and a stent could not be placed in the third because of a large tracheal diameter. RESULTS Compared with baseline values, clinically significant improvements in health-related quality-of-life measures and pulmonary function testing were seen in patients who underwent central airway stabilization (n = 9). Complications of both stent placement and TBP were generally mild. However, one death was reported in the surgical group secondary to an exacerbation of preexisting interstitial pneumonia. CONCLUSIONS An aggressive approach that targets central airway stabilization may improve outcomes for patients with MKS.

True Negative Predictive Value of Endobronchial Ultrasound in Lung Cancer: Are We Being Conservative Enough?

BACKGROUND Cardiothoracic surgery is rapidly evolving to adapt to a changing health care environment and a wider application of innovative techniques. The Society of Thoracic Surgeons Workforce on Thoracic Surgery Resident Issues Transition to Practice Task Force sought to identify new or existing gaps of training in contemporary thoracic surgery residency training programs. METHODS A voluntary survey consisting of 24 questions was distributed to recent graduates of thoracic surgery residency programs in the United States during the 2014 American Board of Thoracic Surgery oral examination application process. Fifty-five of 132 applicants anonymously participated. RESULTS The majority of respondents admitted that they needed more instruction or lacked confidence with the following specific cardiothoracic procedures: minimally invasive cardiac operations (25/52, 48%), robotic cardiac operations (29/52, 55.8%), endovascular operations (28/52, 53.8%), robotic pulmonary operations (29/52, 55.8%), minimally invasive esophageal operations (24/52, 46.2%), robotic esophageal operations (32/52, 61.5%), and operations on congenital cardiac conditions (31/52, 59.6%). The respondents further declared either a need for more instruction or lack of confidence in employment contracting (17/21, 81.0%), negotiating terms of employment (17/21, 81.0%), and professional service agreements (16/21, 76.2%). CONCLUSIONS Further exposure to minimally invasive robotic procedures, operations on congenital conditions, and issues of practice management appear to be needed in contemporary cardiothoracic training in the United States. These identified gaps may assist cardiothoracic surgery residency programs to optimally prepare future graduates for our evolving specialty.

Sternal fracture: isolated lesion versus polytrauma from associated extrasternal injuries--analysis of 1,867 cases.

BACKGROUND Mediastinal staging in patients with non-small cell lung cancer (NSCLC) with endobronchial ultrasound-guided fine-needle aspiration (EBUS-FNA) requires a high negative predictive value (NPV) (ie, low false negative rate). We provide a conservative calculation of NPV that calls for caution in the interpretation of EBUS results. METHODS We retrospectively analyzed our prospectively gathered database (January 2007 to November 2011) to include NSCLC patients who underwent EBUS-FNA for mediastinal staging. We excluded patients with metastatic NSCLC and other malignancies. We assessed FNAs with rapid on-site evaluation (ROSE). The calculation of NPV is NPV = true negatives/true negatives + false negatives. However, this definition ignores nondiagnostic samples. Nondiagnostic samples should be added to the NPV denominator because decisions based on nondiagnostic samples could be flawed. We conservatively calculated NPV for EBUS-FNA as NPV = true negatives/true negatives + false negatives + nondiagnostic. We defined false negatives as negative FNAs but NSCLC-positive surgical biopsy of the same site. Nondiagnostic FNAs were nonrepresentative of lymphoid tissue. We compared diagnostic performance with the inclusion and exclusion of nondiagnostic procedures. RESULTS We studied 120 patients with NSCLC who underwent EBUS-FNA; 5 patients had false negative findings and 10 additional patients had nondiagnostic results. The NPV with and without inclusion of nondiagnostic samples was 65.9% and 85.3%, respectively. CONCLUSIONS The inclusion of nondiagnostic specimens into the conservative, worst-case-scenario calculation of NPV for EBUS-FNA in NSCLC lowers the NPV from 85.3% to 65.9%. The true NPV is likely higher than 65.9% as few nondiagnostic specimens are false negatives. Caution is imperative for the safe application of EBUS-FNA in NSCLC staging.

Sublobar resection with brachytherapy mesh for stage I non-small cell lung cancer

BACKGROUND Sternal fractures fall into two distinct categories as follows: (1) isolated sternal fracture (ISF) without associated injury and (2) polytrauma sternal fracture (PSF) with associated extrasternal injury. PSF can be sufficiently severe to require hospitalization, while ISF is usually a mild insult manageable in an ambulatory setting. Nonetheless, most patients with ISF are hospitalized. The disconnect between treatment based on existing evidence and actual clinical practice may be caused in large part by the small patient cohorts in published studies conducive to inaccurate conclusions. This article addresses the issue by analyzing prospectively collected data on a far larger population than hitherto available. METHODS The Israeli National Trauma Registry (INTR) collects data prospectively on patients admitted to trauma centers in Israel. We analyzed the INTR database on sternal fractures for demographics, mechanisms and severity of injury, diagnostic evaluation, treatment, and outcomes. RESULTS Between 1997 and 2008, the INTR received data on 1,867 consecutive patients hospitalized with sternal fractures. The injury was sustained most often during motor vehicle accidents (84.1%), followed by falls (10.3%) and other blunt or penetrating mechanisms (5.6%). ISF was sustained in 26.4%, and PSF was sustained in 73.6%. Associated injuries involved most parts of the body. Cardiac contusions or lacerations were diagnosed in 1.8% of the 1,867 patients. ISF was associated with a lower incidence of cardiorespiratory compromise, more favorable trauma scores (Glasgow Coma Scale [GCS] score > 14, Revised Trauma Score > 11), and use of fewer intensive care facilities or operations compared with PSF. Endotracheal intubation, chest tube insertion, or thoracotomy was not performed in any ISF patient but was performed in 16.9% of the PSF cohort. The differences between ISF and PSF were statistically significant in all analyzed indices of injury severity. CONCLUSION This study produced compelling evidence that ISF is an identifiable and mild injury. Consequently, pain, the major clinical manifestation of ISF, can usually be treated in outpatient settings. To avoid the inconvenience, risk of complications, and cost associated with hospitalization, discharge from the emergency department merits serious consideration.

Resident Perceptions of 2-Year Versus 3-Year Cardiothoracic Training Programs

Lobar resection is currently the standard approach for the treatment of stage I non-small cell lung cancer. Sublobar resection is generally considered a compromise, reserved for high-risk patients because of greater rates of local recurrence compared with lobar resection. Adjuvant radiation therapy may decrease these increased local recurrence rates, but because of respiratory motion and difficulties in identifying the staple line, radiation delivery can be challenging with an external beam approach. Adjuvant intraoperative brachytherapy with the use of low-dose rate iodine-125 seeds placed alongside the surgical staple has been used with success in several centers. A randomized multicenter North American study has also recently completed accrual, but the results of this are not yet available. In the following review, we outline the techniques used, safety considerations, and currently available outcomes of sublobar resection with adjuvant brachytherapy for non-small cell lung cancer.

Clamshell Thoracotomy: A Unique Approach to a Massive Intrathoracic Schwannoma

BACKGROUND Resident perceptions of 2-year (2Y) vs 3-year (3Y) programs have never been characterized. The objective was to use the mandatory Thoracic Surgery Residents Association and Thoracic Surgery Directors Association In-Training Examination survey to compare perceptions of residents graduating from 2Y vs 3Y cardiothoracic programs. METHODS Each year Accreditation Council for Graduate Medical Education cardiothoracic residents are required to take a 30-question survey designed by the Thoracic Surgery Residents Association and the Thoracic Surgery Directors Association accompanying the In-Training Examination with a 100% response rate. The 2013 and 2014 survey responses of residents graduating from 2Y vs 3Y training programs were compared. The Wilcoxon signed rank test was used to analyze ordinal and interval data. RESULTS Graduating residents completed 167 surveys, including 96 from 2Y (56%) and 71 from 3Y (43%) programs. There was no difference in the perception of being prepared for the American Board of Thoracic Surgery examinations or amount of debt between 2Y and 3Y respondents. There was no difference in intended academic vs private practice. Graduating 3Y residents felt more prepared to meet case requirements and better trained, were more likely to pass their written American Board of Thoracic Surgery examinations, and were less likely to pursue additional training beyond their cardiothoracic residency. CONCLUSIONS There was no difference in field of interest, practice type, and amount of debt between graduating 2Y vs 3Y residents. Respondents from 2Y programs expressed more difficulty in meeting case requirements, whereas residents from 3Y programs felt more prepared for independent practice and had higher American Board of Thoracic Surgery written pass rates.

The Intersection of GERD, Aspiration, and Lung Transplantation

Schwannomas (neurilemmomas) are benign tumors arising from the Schwann cells of the neural sheath. They are typically well-encapsulated lesions and in the chest they are most commonly seen within the posterior mediastinum, often originating along the intercostal nerves. Several operative approaches have previously been described for the resection of these tumors, including thoracoscopic techniques and posterolateral thoracotomy. We report a case of a massive schwannoma (27 cm, maximum diameter), unresectable by described approaches, which was successfully excised using a clamshell thoracotomy.
