Outpatient air leak management after lobectomy: a CMS cost analysis.

BACKGROUND: Air leaks after lobectomy are associated with increased length of stay (LOS) and protracted resource utilization. Portable drainage systems (PDS) allow for outpatient management of air leaks in patients otherwise meeting discharge criteria. We evaluated the safety and cost efficiency of a protocol for outpatient management of air leaks with a PDS. METHODS: We retrospectively assessed patients who underwent lobectomy for non-small-cell lung cancer at our institution between 2004 and 2014. All patients discharged with a PDS for air leak were included in the analysis. The study group was compared to an internally matched cohort of patients undergoing lobectomy for non-small-cell lung cancer managed without the need for outpatient PDS. Study end points included resource utilization, postoperative complications, and readmission. RESULTS: A total of 739 lobectomies were performed during the study period, 73 (10%) patients with air leaks were discharged with a PDS after fulfilling postoperative milestones. Shorter LOS was observed in the study group (3.88 ± 2.4 versus 5.68 ± 5.7 d, P = 0.014) without significant differences in 30-d readmission (11.7% versus 9.0%, P = 0.615). PDS-related complications occurred in 6.8% of study patients (5/73), and 2.7% (2/73) required overnight readmission. PDSs were used for 8.30 ± 4.5 outpatient days. A CMS-based cost analysis predicted an overall savings of $686.72/patient (4.9% of Medicare reimbursement for a major thoracic procedure), associated with significantly fewer hospital days and resources used. CONCLUSIONS: In patients otherwise meeting discharge criteria, outpatient management of air leaks is safe and effective. This strategy is associated with improved efficiency of postoperative care and a modest reduction in hospital costs. This model may be applicable to other thoracic procedures associated with protracted LOS.

Predictors, Morbidity, and Costs Associated with Pneumothorax during Electronic Cardiac Device Implantation.

BACKGROUND: Pneumothorax (PTX) is a major cause of morbidity associated with cardiac implantable electronic devices (CIEDs). We sought to evaluate predictors of PTX at our centers during CIED implantations, including the venous access technique utilized, as well as to determine morbidity and costs associated with PTX. METHODS: We reviewed records of all patients undergoing cardiac device implant or revision with new venous access at our institutions between 2008 and 2014. Common demographic and procedure characteristics were collected including age, sex, body mass index (BMI), comorbidities, and method of venous access (axillary vein vs classic proximal subclavian vein technique). RESULTS: We identified 1,264 patients who met criteria for our analysis, with a total of 21 PTX cases during CIED implantation. The strongest predictor for PTX was the venous access strategy: 0 of 385 (0%) patients with axillary vein approach versus 21 of 879 (2.4%) with traditional subclavian vein approach, P = 0.0006. Additional predictors of PTX included advanced age, female sex, low BMI, and a new device implant (vs device upgrade). The occurrence of PTX was associated with increased length of stay: 3.0 days (median; interquartile range [IQR] 3) versus 1.0 day (median; IQR: 1), P = 0.0001, with a cost increase of 361.4%. CONCLUSION: An axillary vein vascular access strategy was associated with greatly reduced risk of iatrogenic PTX versus the traditional subclavian approach for CIED placement. Similarly, device upgrade with patent vascular access carried less risk of PTX compared to new device implantation. PTX occurrence significantly prolonged hospitalization and increased costs.

Vats Versus Axillary Minithoracotomy in the Management of the Second Episode of Spontaneous Pneumothorax: Cost-Benefit Analysis.

BACKGROUND: Video-assisted thoracic surgery (VATS) was considered the gold standard approach in recurrent spontaneous pneumothorax, with unanimous consensus of opinions. The cost-effectiveness analysis in the surgical treatment of recurrence of primary spontaneous pneumothorax (PSP) was carried out comparing VATS with muscle-sparing axillary minithoracotomy (MSAM). METHODS: Between July 2006 and October 2012 we treated 56 patients with a second episode of PSP by VATS or open approach. Time of intervention, prolonged air leaks, duration of pleural drainage, length of hospitalization, and long-term morbidity were evaluated, establishing the relationship between costs and quality-adjusted life for each technique. RESULTS: The assessment of pain and threshold of tenderness was more favorable in VATS in respect to MSAM during the 5 years of follow-up (p = 0.004 and <0.001 at 1st year; p = 0.006 and <0.002 at 5th year). The minimally invasive method was less expensive than axillary minithoracotomy (2443.44 € vs. 3170.80 €). The quality-adjusted life expectancy of VATS was better than that of MSAM (57.00 vs. 49.2 at 60 months) as well as the quality-adjusted life year (0.03 at 1st year and 0.13 at 5th year). Incremental cost per life year gained of VATS versus MSAM was between 24,245.33 € (1st year) and 5776.31 € (5th year), making it advantageous at 3rd, 4th, and 5th years. CONCLUSIONS: VATS compared to MSAM in the treatment of a second episode of PSP ensured undoubted clinical advantages associated with significant cost savings.

Outpatient Treatment of Pneumothorax with a Thoracic Vent: Economic Benefit.

BACKGROUND: Since rising medical costs currently represent a growing problem worldwide, finding cost-effective treatment options is important. In our hospital, outpatient treatment of pneumothorax using a thoracic vent began in December 2012. OBJECTIVES: We aimed to test our hypothesis that outpatient treatment of pneumothorax with a thoracic vent can reduce medical expenses. METHODS: Patients were classified into four groups based on treatment: thoracic vent with or without surgery or conventional intercostal chest tube drainage with or without surgery. We compared mean medical expenses, duration of hospitalization and number of physician visits among these four groups. RESULTS: During a 2-year period, 65 patients were treated with a thoracic vent (36 patients) or conventional intercostal chest tube drainage (29 patients). Patients treated with a thoracic vent who underwent surgery had a shorter mean duration of hospitalization (5.0 ± 1.3 vs. 10.3 ± 3.4 days; p < 0.0001) and lower overall cost, at JPY 971,830.00 ± 81,291.80 (USD 10,400.40 ± 1,464.90) versus JPY 1,179,791.10 ± 198,383.10 (USD 13,888.90 ± 1,965.30; p < 0.0001) compared with conventional intercostal chest tube drainage. Nonsurgical patients treated with a thoracic vent had lower overall costs, at JPY 79,960.00 ± 25,643.60 (USD 890.10 ± 352.30) versus JPY 268,588.80 ± 94,636.50 (USD 2,932.80 ± 903.50; p < 0.0001) compared with conventional intercostal chest tube drainage. No serious complications were observed. CONCLUSIONS: Outpatient thoracic vent treatment can significantly reduce medical expenses and thereby have a major economic impact.

Efficacy assessment of the drainage with permanent airflow measurement in the treatment of pneumothorax with air leak.

AIM: The aim of this study was to compare the efficacy of the treatment of patients with spontaneous pneumothorax with air leak (AL) using two different chest drainage systems. METHODS: Patients were randomized into two groups: group A included 30 patients (23 males and 7 females, mean age 41.1 ± 16.29 y, range 17-71 y) in which digital drainage system was used, group B with 30 patients (22 males and 8 females, mean age 40.3 ± 15.74 y, range 18-72 y) in which traditional suction drainage system was applied.The following variables were evaluated: intensity of AL, duration of the chest tube drainage, delay in surgery, length of stay, and the overall hospitalization costs. RESULTS: In group A the mean drainage duration was 47.63 hours, the hospitalization time was about 5.10 days, and the cost of hospitalization was €1,495. In group B the mean drainage duration was 84.93 hours, the hospitalization time was 6.97 days, and the hospitalization cost was €1,925. CONCLUSION: The digital drainage system applied in the treatment of AL in patients with pneumothoraces reduced the duration of the drainage, the length of hospital stay, and overall hospitalization costs.

Video-assisted thoracoscopy as an important tool for trauma surgeons: a systematic review.

PURPOSE: Trauma patients frequently have serious chest injuries. Retained hemothoraces and persistent pneumothoraces are among the most frequent complications of chest injuries which may lead to major, long-term morbidity and mortality if these complications are not recognized and treated appropriately. Video-assisted thoracoscopy (VATS) is a well-established technique in surgical practice. The usefulness of VATS for treatment of complications after chest trauma has been demonstrated by several authors. However, there is an ongoing debate about the optimal timing of VATS. METHODS: A computerized search was conducted which yielded 450 studies reporting on the use of VATS for thoracic trauma. Eighteen of these studies were deemed relevant for this review. The quality of these studies was assessed using a check-list and the PRISMA guidelines. Outcome parameters were successful evacuation of the retained hemothorax or treatment of other complications as well as reduction of empyema rate, length of hospital stay, and hospital costs. RESULTS: There was only one randomized trial and two prospective studies. Most studies report case series of institutional experiences. VATS was found to be very successful in evacuation of retained hemothoraces and seems to reduce the empyema rate subsequently. Furthermore, the length of hospital stay and costs can be drastically reduced with the early use of VATS. CONCLUSION: Early VATS is an effective treatment for retained hemothoraces or other complications of chest trauma. We propose a clinical pathway, in which VATS is used as an early intervention in order to prevent serious complications such as empyemas or trapped lung.

Chest X-ray after tracheostomy is not necessary unless clinically indicated.

BACKGROUND: Chest radiography is routinely used post-tracheostomy to evaluate for complications. Often, the chest X-ray findings do not change clinical management. The present study was conducted to evaluate the utility of post-tracheostomy X-rays. METHOD: This retrospective review of 255 patients was performed at a single-center, university, level I trauma center. All patients underwent tracheostomy and were evaluated for postprocedure complications. RESULTS: Of the 255 patients, 95.7% had no change in postprocedure chest X-ray findings. New significant chest X-ray findings were found in 4.3% of patients, including subcutaneous emphysema, pneumothorax, and new significant consolidation. Only three of these patients required change in clinical management, and all changes were based on clinical presentation alone. CONCLUSIONS: Routine chest X-ray following tracheostomy fails to provide additional information beyond clinical examination. Therefore radiographic examination should be performed only after technically difficult procedures or if the patient experiences clinical deterioration. Significant cost savings and minimization of radiation exposure can be achieved when chest radiography after tracheostomy is performed exclusively for clinical indications.

Ultrasonography guidance reduces complications and costs associated with thoracentesis procedures.

PURPOSE.: We performed an analysis of hospitalizations involving thoracentesis procedures to determine whether the use of ultrasonographic (US) guidance is associated with differences in complications or hospital costs as compared with not using US guidance. METHODS.: We used the Premier hospital database to identify patients with ICD-9 coded thoracentesis in 2008. Use of US guidance was identified using CPT-4 codes. We performed univariate and multivariable analyses of cost data and adjusted for patient demographics, hospital characteristics, patient morbidity severity, and mortality. Logistic regression models were developed for pneumothorax and hemorrhage adverse events, controlling for patient demographics, morbidity severity, mortality, and hospital size. RESULTS.: Of 19,339 thoracentesis procedures, 46% were performed with US guidance. Mean total hospitalization costs were $11,786 (±$10,535) and $12,408 (±$13,157) for patients with and without US guidance, respectively (p < 0.001). Unadjusted risk of pneumothorax or hemorrhage was lower with US guidance (p = 0.019 and 0.078, respectively). Logistic regression analyses demonstrate that US is associated with a 16.3% reduction likelihood of pneumothorax (adjusted odds ratio 0.837, 95% CI: 0.73-0.96; p= 0.014), and 38.7% reduction in likelihood of hemorrhage (adjusted odds ratio 0.613, 95% CI: 0.36-1.04; p = 0.071). CONCLUSIONS.: US-guided thoracentesis is associated with lower total hospital stay costs and lower incidence of pneumothorax and hemorrhage. © 2011 Wiley Periodicals, Inc. J Clin Ultrasound, 2011.

Outpatient management of primary spontaneous pneumothorax.

The outpatient management of primary spontaneous pneumothorax (PSP) is still debated. The risk of a tension pneumothorax is used to justify active treatment like chest-tube drainage, although outpatient management can reduce both the time in hospital and the cost of treatment. It is also likely to be the patient's choice. This report is a reappraisal of the situations for which outpatient management, by monitoring alone, or using minimally invasive techniques, can be considered.

Epidemiology of Adult Pleural Disease in the United States.

BACKGROUND: Comprehensive US epidemiologic data for adult pleural disease are not available. RESEARCH QUESTION: What are the epidemiologic measures related to adult pleural disease in the United States? STUDY DESIGN AND METHODS: Retrospective cohort study using Healthcare Utilization Project databases (2007-2016). Adults (≥ 18 years of age) with malignant pleural mesothelioma, malignant pleural effusion, nonmalignant pleural effusion, empyema, primary and secondary spontaneous pneumothorax, iatrogenic pneumothorax, and pleural TB were studied. RESULTS: In 2016, ED treat-and-discharge (T&D) visits totaled 42,215, accounting for charges of $286.7 million. In 2016, a total of 361,270 hospitalizations occurred, resulting in national costs of $10.1 billion. A total of 64,174 readmissions contributed $1.16 billion in additional national costs. Nonmalignant pleural effusion constituted 85.5% of ED T&D visits, 63.5% of hospitalizations, and 66.3% of 30-day readmissions. Contemporary sex distribution (male to female ratio) in primary spontaneous pneumothorax (2.1:1) differs from older estimates (6.2:1). Decadal analyses of annual hospitalization rates/100,000 adult population (2007 vs 2016) showed a significant (P < .001) decrease for malignant pleural mesothelioma (1.3 vs 1.09, respectively), malignant pleural effusion (33.4 vs 31.9, respectively), iatrogenic pneumothorax (17.9 vs 13.9, respectively), and pleural TB (0.20 vs 0.09, respectively) and an increase for empyema (8.1 vs 11.1, respectively) and nonmalignant pleural effusion (78.1 vs 100.1, respectively). Empyema hospitalizations have high costs per case ($38,591) and length of stay (13.8 days). The mean proportion of readmissions attributed to a pleural cause varied widely: malignant pleural mesothelioma, 49%; malignant pleural effusion, 45%; nonmalignant pleural effusion, 31%; empyema, 27%; primary spontaneous pneumothorax, 27%; secondary spontaneous pneumothorax, 27%; and iatrogenic pneumothorax, 20%. Secondary spontaneous pneumothorax had the shortest time to readmission in 2016 (10.3 days, 95% CI, 8.8-11.8 days). INTERPRETATION: Significant epidemiologic trends and changes in various pleural diseases were observed. The analysis identifies multiple opportunities for improvement in management of pleural diseases.

Digital air leak monitoring after lobectomy for primary lung cancer in patients with moderate COPD: can a fast-tracking algorithm reduce postoperative costs and complications?

AIM: Prolonged air leaks remain one of the most important complication after pulmonary resection. The aim of this study was to test a new fast-track chest tube removal protocol using a new drainage system, which digitally records postoperative air leaks, compared to the traditional one, with subjective visual air leak assessment. METHODS: Patients with moderate COPD undergoing lobectomy for primary lung cancer at the Department of Thoracic Surgery of the University of Torino were randomised in two groups with different chest drainage systems and different removal protocols: in Group A the drainage was removed after digitally recordered measurement of air leaks; in Group B the tube was removed according to the air leaks visualization by bubbling in the water column. The following variables were evaluated: first and second drainage removal day; overall hospital length of stay; overall hospitalization costs. RESULTS: First and second drainages were removed sooner in those patients with the digital drainage system. An earlier drainage removal is associated with significative reduction in hospital length of stay and overall hospitalization costs. CONCLUSION: The digital and continuous air leak measurement reduces the hospital length of stay by a more accurate and reproductive air leaks measurement. Further studies are mandatory to corroborate our preliminary results.

Ultrasound-guided central line placement as compared with standard landmark technique: some unpleasant arithmetic for the economics of medical innovation.

OBJECTIVE: We perform a simple cost estimation of ultrasound guidance for the placement of central venous access, considering the US federal reimbursement for ultrasound guidance of central line placement to the federal reimbursement for treating the complication of pneumothorax. METHODS: We utilize national statistics on the number of central lines placed annually to determine the cost savings incurred if all central lines placed in the United States were placed with ultrasound guidance. RESULTS: The initial "cost" of placing central lines was found to be 390,780,000 to 651,300,000 dollars per year by the landmark technique, as compared with 494,820,000 to 824,700,000 dollars per year by ultrasound guidance. CONCLUSIONS: The cost of ultrasound guidance was not mitigated by its reduction in the cost of treating pneumothoraces.

Pacemaker complications and costs: a nationwide economic study.

Aims: Novel leadless pacemakers (LPMs) may reduce complications and associated costs related to conventional pacemaker systems. This study sought to estimate the incidence and associated costs of traditional pacemaker complications, in those patients who were eligible for LPM implantation. Methods: A retrospective analysis was conducted on the French National Hospital Database (PMSI), including all patients implanted with a pacemaker in France in 2012, who could have alternatively received an LPM. Complication rates and their associated costs 3 years post-implantation were estimated from the perspective of the French social security system. Results: From a total of 65,553 patients, 11,770 (18%) met the inclusion criteria. Overall, 618 patients (5.3%) had a record of pacemaker complications during follow-up, of which 89% were related to the lead and pocket. Most common were pocket bleeding, lead- or generator-related mechanical complications, and pneumothorax. Overall, the mean cost of pacemaker complications per patient was €6,674 ± 3,867 at 3 years. Specifically, €7,143 ± 2,685 for pocket bleeding, €5,123 ± 2,676 for pneumothorax, and €6,020 ± 3,272 for mechanical complications. Conclusions: Major complications associated with the lead and pocket of conventional pacemaker systems are still common, and these represent a significant burden to healthcare systems as they generate substantial costs.

Medical Thoracoscopy-Assisted Argon Plasma Coagulation Combined with Electrosurgical Unit for the Treatment of Refractory Pneumothorax in Elderly Patients.

PURPOSE: This study aims to compare the effects and prognosis of medical thoracoscopy-assisted argon plasma coagulation (APC) combined with electrosurgical unit (ESU) surgery, video-assisted thoracic surgery (VATS), and pleurodesis surgery, in providing appropriate treatment for elderly refractory pneumothorax patients. METHODS: Patients with refractory pneumothorax aged over 65 years were divided into three groups: APC combined with ESU (N = 20), VATS (N = 26), and pleurodesis (N = 24). Data on demographic characteristics, lung function evaluation, and short- and long-term prognoses were collected. RESULTS: Following surgery, compared with the APC-ESU and pleurodesis groups, patients in the VATS group demonstrated poor short-term prognoses, with high pleural effusion drainage levels and high visual analog scores (VAS; P <0.05). After the surgery, St. George's Respiratory Questionnaire (SGRQ) scores in the pleurodesis group were slightly elevated, whereas SGRQ scores in both the APC-ESU and VATS groups demonstrated a continual decrease. Finally, medical resource consumption analysis demonstrated a significant difference in hospitalization costs among the three groups; the VATS group being the most expensive. CONCLUSION: Medical thoracoscopy-assisted APC combined with ESU is a safe, effective, and affordable treatment for elderly patients with refractory pneumothorax.

Epidemiology and medical service use for spontaneous pneumothorax: a 12-year study using nationwide cohort data in Korea.

OBJECTIVE: This study aimed to promote an understanding of spontaneous pneumothorax by analysing the prevalence rate and medical service use by patients with spontaneous pneumothorax according to sociodemographic characteristics. DESIGN: A 12-year nationwide study. SETTING: Data obtained from the Korean National Health Insurance Service Sharing Service. PARTICIPANTS: A total of 4658 participants who used medical services due to spontaneous pneumothorax between 2002 and 2013 in Korea. OUTCOME MEASURES: For those diagnosed with spontaneous pneumothorax, use of medical services, hospitalisation data, sociodemographics, comorbidity, treatment administered and medication prescribed were recorded. RESULTS: The annual prevalence of spontaneous pneumothorax ranged from 39 to 66 per 100 000 individuals, while the prevalence of hospitalisation due to spontaneous pneumothorax ranged from 18 to 36 per 100 000 individuals. The prevalence rate of spontaneous pneumothorax in Korea has increased since 2002. The male to female ratio was approximately 4-10:1, with a higher prevalence rate in men. By age, the 15-34 years old group, and particularly those aged 15-19 years old, showed the highest prevalence rate; the rate then declined before increasing again for those aged 65 years or older. In total, 47%-57% of patients with spontaneous pneumothorax underwent hospitalisation. The average number of rehospitalisations due to pneumothorax was 1.56 per person, and more than 70% of recurrences occurred within 1 year. Chronic obstructive pulmonary disease was the most common comorbidity. The average treatment period was 11 days as an outpatient and 14 days in-hospital. The average medical costs were $94.50 for outpatients and $2523 for hospital admissions. The most common treatment for spontaneous pneumothorax was oxygen inhalation and thoracostomy, and the most commonly prescribed medications were analgesics, antitussives and antibiotics. CONCLUSIONS: We here detailed the epidemiology and treatments for spontaneous pneumothorax in Korea. This information can contribute to the understanding of spontaneous pneumothorax.

Air leaks after lobectomy increase the risk of empyema but not of cardiopulmonary complications: a case-matched analysis.

PURPOSE: To assess whether the presence and duration of air leaks after lobectomy are associated with an increased incidence of cardiopulmonary complications. METHODS: Propensity score analysis was used on 726 patients undergoing pulmonary lobectomy from 1995 through 2004 to form three well-matched pairs of patients: patients with prolonged air leak (PAL) [> 7 days] and without air leak; patients with short air leak (SAL) [< or = 7 days] and without air leak; and patients with SAL and PAL. These matched groups were then compared to assess postoperative hospital stay and early outcome. RESULTS: Patients with SAL had a longer postoperative hospital stay compared to patients without air leak (8.6 days vs 7.8 days, respectively; p < 0.0001) but had similar morbidity and mortality. Patients with PAL had a longer postoperative hospital stay compared to patients without air leak (16.2 days vs 8.3 days, respectively; p < 0.0001) and with SAL (16.9 days vs 9 days, respectively; p < 0.0001), but similar cardiopulmonary complications were noted between the groups. Patients with PAL had a higher rate of empyema compared to patients without air leak and with SAL (8.2% vs 0%, p = 0.01 and 10.4% vs.1.1%, p = 0.01, respectively). CONCLUSIONS: The presence of air leak was not associated with an increased incidence of cardiopulmonary morbidity but was associated with an increased risk of empyema. Future prospective studies are needed to confirm safety of fast track in patients with air leak.

Chest radiograph after fluoroscopic guided line placement: No longer necessary.

PURPOSE: Historically, a chest radiograph was obtained after central line placement in the operating room. Recent retrospective studies have questioned the need for this radiograph. The prevailing current practice at our center is to order chest radiograph only for symptomatic patients. This study examines the outcomes of selective chest radiography after fluoroscopic guided central line placement. METHODS: After obtaining institutional review board approval, a single institution retrospective chart review of patients undergoing central venous catheter placement by the pediatric surgery or interventional radiology service between January 2010 and July 2014 was performed. Outcome measures included CXR within 24h of catheter placement, reason for chest radiograph, complication, and complication requiring intervention. RESULTS: In the study population 622 catheters were placed under fluoroscopy. A chest radiograph was performed in 118 (19%) patients within 24h of the line placement with 25 (4%) of these patients being symptomatic in the recovery room. One patient required chest tube for shortness of breath and pleural effusion. Four symptomatic patients (0.6%) were found to have a pneumothorax, none of which required chest tube placement. There were no re-operations because of mal-position of the catheter. In the 504 patients with no postoperative chest x-ray, there were no adverse outcomes. At our institution the current average charge of a chest radiograph is $283, thus we produced savings of $142,632 for the study period without adverse events. CONCLUSION: After placement of central venous catheter under fluoroscopic guidance, a chest radiograph is unlikely to be helpful in an asymptomatic patient.

Utilization of the track embolization technique to improve the safety of percutaneous lung biopsy and/or fiducial marker placement.

PURPOSE: The purpose of the study was to describe and present outcomes of the track embolization technique with absorbable hemostat gelatin powder during percutaneous computed tomography (CT)-guided lung biopsy and/or fiducial marker placement versus the standard of care (no track embolization) in an attempt to decrease rates of pneumothorax (PTX), chest tube placement, hemorrhage and/or complications, and average cost per patient. MATERIALS AND METHODS: An institutional review board-approved, case-control, retrospective study was performed in which 125 consecutive patients who underwent track embolization were compared with 124 consecutive controls at one institution. For subjects in whom the track embolization technique was utilized, it was performed passively through a coaxial needle as it was removed. All procedures were performed by one of three attending interventional radiologists. For each group, medical records and procedure images were reviewed for PTX occurring postprocedure, PTX requiring chest tube placement, and occurrence of minor or major complication and/or hemorrhage. Comparison was made with published complication rates, and a cost-per-patient analysis was performed. Statistical analysis was performed utilizing Fisher's Exact Test. RESULTS: In track embolization cases versus controls, there were statistically significant reduction in PTX (8.8% vs. 21%; P=.007) and reduction in PTX requiring chest tube placement (4% vs. 8.1%; P=.195). This compares favorably to previously published rates of PTX and chest tube placement of 8%-64% and 1.6%-17%, respectively. None of the pneumothoraces occurring at time of needle placement increased in size with use of the track embolization technique. There were no major complications (including neurological sequela) in the track embolization group. In track embolization cases versus controls, there was a statistically significant reduction in both the rate of major hemorrhage (0% vs. 4%; P=.029) and average cost per patient ($262.40 vs. $352.07; P=.044). CONCLUSIONS: CT-guided percutaneous lung biopsy and/or fiducial marker placement were safer utilizing the track embolization technique during trocar removal. In addition, this technique was cost effective in the study population.

Video-assisted thoracic surgery versus pleural drainage in the management of the first episode of primary spontaneous pneumothorax.

BACKGROUND: The aim of the study was to analyze the cost-effectiveness outcomes of video-assisted thoracic surgery (VATS) in the treatment of primary spontaneous pneumothorax (PSP), comparing the minimally invasive procedure with pleural drainage (PD). METHODS: Between July 2006 and October 2012, we treated 122 patients with a first episode of PSP by VATS (61 patients) or pleural drainage (61 patients). We established the relationship between costs and quality-adjusted life (QAL) for both techniques. RESULTS: The total cost per patient of minimally invasive procedure was more advantageous than that of chest tube (€2,422.96 vs €4,855.12). The QAL expectancy of VATS was longer than that of PD (57.00 vs 40.80 at 60 months). The QAL year of VATS (.32 at 1st year and .25 at 5th year) was better than that of PD. Incremental cost-effectiveness ratio of VATS versus PD was between €7,600.00 (1st year) and €10,045.00 (5th year), remaining well below the threshold of acceptability. CONCLUSION: VATS as the first-line treatment for PSP allowed low morbidity, short hospitalization, and excellent quality of life.
