Assessment of the availability of technology for trauma care in India.

BACKGROUND: We sought to assess the status of availability of technology for trauma care in a state in India and to identify factors contributing to both adequate levels of availability and to deficiencies. We also sought to identify potential solutions to deficiencies in terms of health system management and product development. METHODS: Thirty-two technology-related items were selected from the World Health Organization's Guidelines for Essential Trauma Care. The status of these items was assessed at 43 small and large hospitals in Gujarat State. Site visits utilized direct inspection and interviews with administrative, clinical, and bioengineering staff. RESULTS: Many specific individual items could be better supplied, including many that were very low cost (e.g., chest tubes). Many deficiencies arose because of mismatch of resources, such as availability of equipment in the absence of personnel trained to use it. Several locally manufactured items were fairly well supplied: pulse oximetry, image intensification, and X-ray machines. Ventilators were often deficient because of inadequate numbers of units and frequent breakdowns. CONCLUSIONS: Availability of a range of lower-cost items could be improved by better organization and planning, such as: better procurement and stock management; eliminating mismatch of resources, including optimizing training for use of existing resources; and by strengthening service contracts and in-house repair capabilities. From a product development viewpoint, there is a need for lower cost, more durable, and easier to repair ventilators. Promoting increased capacity for local manufacturing should also be considered as a potential method to decrease cost and increase availability of a range of equipment.

The opioid rotation ratio of hydrocodone to strong opioids in cancer patients.

PURPOSE: Cancer pain management guidelines recommend initial treatment with intermediate-strength analgesics such as hydrocodone and subsequent escalation to stronger opioids such as morphine. There are no published studies on the process of opioid rotation (OR) from hydrocodone to strong opioids in cancer patients. Our aim was to determine the opioid rotation ratio (ORR) of hydrocodone to morphine equivalent daily dose (MEDD) in cancer outpatients. PATIENTS AND METHODS: We reviewed the records of consecutive patient visits at our supportive care center in 2011-2012 for OR from hydrocodone to stronger opioids. Data regarding demographics, Edmonton Symptom Assessment Scale (ESAS), and MEDD were collected from patients who returned for follow-up within 6 weeks. Linear regression analysis was used to estimate the ORR between hydrocodone and MEDD. Successful OR was defined as 2-point or 30% reduction in the pain score and continuation of the new opioid at follow-up. RESULTS: Overall, 170 patients underwent OR from hydrocodone to stronger opioid. The median age was 59 years, and 81% had advanced cancer. The median time between OR and follow-up was 21 days. We found 53% had a successful OR with significant improvement in the ESAS pain and symptom distress scores. In 100 patients with complete OR and no worsening of pain at follow-up, the median ORR from hydrocodone to MEDD was 1.5 (quintiles 1-3: 0.9-2). The ORR was associated with hydrocodone dose (r = -.52; p < .0001) and was lower in patients receiving ≥40 mg of hydrocodone per day (p < .0001). The median ORR of hydrocodone to morphine was 1.5 (n = 44) and hydrocodone to oxycodone was 0.9 (n = 24). CONCLUSION: The median ORR from hydrocodone to MEDD was 1.5 and varied according to hydrocodone dose.

Unilateral intestinal lung disease misdiagnosed as rheumatoid lung disease. A case report of absent pulmonary artery.

Unilateral absence of pulmonary artery (UAPA) is a congenital clinical abnormality that is rarely diagnosed in adulthood. Due to its rarity and heterogeneity as it pertains to its clinical presentation, it may be difficult to diagnose, often leading to misdiagnosis. We present a case of UAPA with unilateral pulmonary fibrosis which was misdiagnosed as rheumatoid arthritis-associated interstitial lung disease (RA-ILD). We describe the symptomology, physical examination findings, laboratory values and radiologic findings. We also describe the diagnostic challenges and approach to a patient presenting with unilateral interstitial lung disease (ILD) and highlight the importance of a comprehensive evaluation.

Successful hemostasis in refractory alveolar hemorrhage using low-dose recombinant activated factor VII.

Diffuse alveolar hemorrhage (DAH) is a life-threatening condition requiring prompt recognition. Conventional therapy, even when initiated early, may not have an immediate effect, and in severe cases, bleeding can persist despite treatment. We report the case of a previously healthy 33-year-old male who developed DAH secondary to granulomatosis with polyangiitis, resulting in respiratory failure and the need for mechanical ventilation. High-dose corticosteroids, plasma exchange, and remission induction with cyclophosphamide failed to control bleeding, leading to severely impaired gas exchange. 20 mcg/kg of systemic recombinant activated Factor VII (rFVIIa), a dose lower than previously reported for management of DAH, resulted in hemostasis and improved oxygenation after only three doses. No complications were observed, and our patient was liberated from ventilatory support eight days later. In the setting of DAH with refractory bleeding, hemostasis may be achievable with a lower dose of rFVIIa than commonly used, potentially mitigating the risk of dose-dependent side effects.

In-hospital complications associated with total artificial heart implantation in the United States between 2004 to 2011.

OBJECTIVE: Total artificial heart (TAH) utilization has increased over the recent years. The goal of this study was to evaluate the trend of artificial hearts used in the USA with its associated morbidity and mortality based on a large in-hospital database. MATERIALS AND METHODS: Using a very large nationwide inpatient samples (NIS) database, we used ICD-9 code for a total artificial heart. We evaluated the utilization of this device over the years studied. Furthermore, we evaluated any associated complications and mortality in patients receiving this device. RESULTS: From 2004 until 2011, the rate of total artificial heart implants increased over the years from 5 in 2004 to the highest of 26 in 2011 across the United State. TAH was insesrted in 75 patients. Death was reported in 22 patients (29.3%). Acute renal failure was the most common complication (69.3%). This is followed by post-operative infectious complications (28.0%), acute renal failure requiring dialysis (16%), bleeding complications requiring blood transfusion (14.7%) respiratory complications (6.7%), and stroke/TIA (4.0%). There was no post-operative deep vein thrmobosis or pulmonary embolism. CONCLUSIONS: The use of total artificial heart has increased in the United State steadily with substantial morbidity and mortality associated with this device.

Endobronchial Valves Therapy for Advanced Emphysema: A Meta-Analysis of Randomized Trials.

BACKGROUND: Trials suggest that bronchoscopic lung volume reduction (BLVR) with endobronchial valve (EBV) implantation may produce similar effects as lung volume reduction surgery, by inducing atelectasis and reducing hyperinflation through a minimally invasive procedure. This study sought to investigate the efficacy and safety of BLVR with EBV for advanced emphysema. METHODS: We searched PubMed, EMBASE, Web of Science, CINAHL, ClinicalTrials.gov, and Cochrane Library databases for randomized controlled trials comparing EBV implantation versus standard medical treatment or sham bronchoscopy. The main outcome of interest was the percentage change of forced expiratory volume in 1 second. RESULTS: Data analyzed from 5 randomized controlled trials with 703 patients revealed improvement in percentage change of forced expiratory volume in 1 second in EBV group compared with control group [weighted mean difference (WMD)=11.43; 95% confidence interval (CI), 6.05-16.80; P<0.0001] and improvement in the St. George's Respiratory Questionnaire score (WMD=-5.69; 95% CI, -8.67 to -2.70; P=0.0002). There is no difference shown in the 6-minute walking test (WMD=14.12; 95% CI, -4.71 to 32.95; P=0.14). The overall complication rate of EBV was not significantly different except for an increased rate of pneumothorax [relative risk (RR)=8.16; 95% CI, 2.21-30.11; P=0.002), any hemoptysis (RR=5.01; 95% CI, 1.12-22.49; P=0.04)] and valve migration (RR=8.64; 95% CI, 2.01-37.13; P=0.004). CONCLUSION: BLVR using EBV shows short-term improvement in lung function and quality of life, but with increased risk of minor hemoptysis, pneumothorax, and valve migration. Follow-up data on the studies are needed to determine its long-term efficacy.

Decreased In-Hospital Mortality after Lobectomy Using Video-assisted Thoracoscopic Surgery Compared with Open Thoracotomy.

RATIONALE: There is a paucity of data regarding the optimal surgical approach for lung lobectomy. Lobectomy performed by video-assisted thoracoscopic surgery (VATS) has been associated with lower morbidity as compared with lobectomy performed by thoracotomy. However, no multicenter studies have shown improved mortality with VATS lobectomy compared with open surgical lobectomy. OBJECTIVES: We used data from the United States Healthcare Cost and Utilization Project Nationwide Inpatient Sample database from 2009 to 2012 to compare VATS with open lobectomy for in-hospital mortality and other short-term outcomes. METHODS: We used International Classification of Diseases, Ninth Revision, Clinical Modification procedure codes to identify the patients undergoing lobectomy. We used 1:1 ratio propensity matching with the nearest neighbor method without replacement to generate matched pairs. MEASUREMENTS AND MAIN RESULTS: Over the 4-year period, 27,451 patients underwent lobectomy. The majority of these procedures were performed by thoracotomy (65%) as compared with VATS (35%). A total of 9,393 matched pairs were created. VATS lobectomy was associated with significantly lower in-hospital mortality when compared with thoracotomy (1.3% vs. 2.5%, P < 0.001). A shorter length of hospital stay was observed for those undergoing VATS lobectomy (6.21 vs. 8.75 d, P < 0.001). The overall rate of perioperative complications was low, with those undergoing VATS being less likely to have any perioperative morbidity. CONCLUSIONS: In recent years, the use of VATS for lobectomy has increased relative to thoracotomy. This trend has coincided with increased survival and shorter length of stay for VATS lobectomy compared with thoracotomy. Further studies are needed to identify comorbidities that identify ideal candidates for VATS lobectomy.

Pulmonary Embolism with Right Ventricular Dysfunction: Who Should Receive Thrombolytic Agents?

BACKGROUND: Appropriate management of pulmonary embolism patients with right ventricular dysfunction is uncertain. Recent guidelines have stressed the need for more data on the use of thrombolytic agents in the stable pulmonary embolism patient with right ventricular dysfunction. The objective of this study is to investigate the hypothesis that thrombolytic therapy in hemodynamically stable pulmonary embolism patients with right ventricular dysfunction is not associated with improved mortality. METHODS: We did a retrospective analysis using multi-institutional observational data from the Nationwide Inpatient Sample database. International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes were used to identify the patients with pulmonary embolism and right ventricular dysfunction. In-hospital mortality was defined as the primary outcome of interest. RESULTS: Over the 4 years of the study period, 3668 patients with right ventricular dysfunction and pulmonary embolism were found, of which 3253 patients were identified as having hemodynamically stable right-sided heart failure with pulmonary embolism. There was no significant difference in mortality between hemodynamically stable pulmonary embolism patients with right ventricular dysfunction who received thrombolytic agents compared with those who did not. When outcomes were assessed for patients with right ventricular dysfunction and hemodynamic instability, a significant improvement in mortality was noted for patients with right ventricular dysfunction who received thrombolytic agents, which confirmed previous reports that thrombolytic therapy decreases mortality in pulmonary embolism patients who are hemodynamically unstable. CONCLUSION: Our data support the use of less aggressive treatment for stable pulmonary embolism patients with right ventricular dysfunction. These results argue against the reflexive use of thrombolytic agents in stable pulmonary embolism patients with right ventricular dysfunction.

A Novel Way of Treating Multidrug-resistant Enterococci.

CONTEXT: Daptomycin is the only antibiotic available with in vitro bactericidal activity against vancomycin-resistant enterococci (VRE). Its increased use has resulted in cases of decreased daptomycin efficacy. Recent in vitro studies have shown effective use of beta (ß)-lactam and daptomycin antibiotics, as a combination therapy, in the treatment of VRE. We describe a case of effective treatment in a patient with VRE infection using dual ampicillin and daptomycin therapy that shows bench-to-bedside application of the abovementioned finding. CASE REPORT: A 76-year-old gentleman with a history of bilateral arthroplasty was admitted with a swollen left knee. Blood cultures were positive for Enterococcus faecium. Left knee joint aspiration showed leukocytosis and alpha defensins. Extensive imaging did not show any other source of infection. Culture sensitivity results showed multidrug-resistant enterococci sensitive to daptomycin. The patient was started on intravenous (IV) daptomycin. His left knee prosthesis was explanted and a spacer was placed. The patient continued to be bacteremic for 10 days after removing the knee prosthesis. The patient was trialed on combination IV ampicillin and daptomycin. His blood culture turned negative 2 days later. The patient was discharged home to continue 6 weeks of IV ampicillin and daptomycin. CONCLUSION: The exact mechanism of the daptomycin/ampicillin synergy effect is unclear. Current hypothesis suggests that ampicillin causes a reduction in the net positive charge of the bacterial surface, possibly by releasing lipoteichoic acid (LTA) from the cell wall. This process increases the ability of the cationic daptomycin/calcium complex to bind to the cell wall more effectively. Our case shows the clinical application of the same. A prospective randomized control trial to explore the effectiveness of dual antibiotic therapy in vivo is needed. If proven, daptomycin/ß-lactam can become a standard of care to treat VRE and decrease daptomycin nonsusceptibility.

Gastrointestinal bleeding secondary to trimethoprim-sulfamethoxazole-induced vitamin K deficiency.

There is a well-known association between vitamin K deficiency and haemorrhagic events including gastrointestinal bleeding. There is also a well-known association between both poor dietary intake of vitamin K and chronic antibiotic use and the development of vitamin K deficiency. Although the medical literature notes that cephalosporin antibiotics have a propensity to cause vitamin K deficiency due to the molecular structure of the medications and their ability to suppress the synthesis of clotting factors, there are other antibiotics that have also been implicated in the development of vitamin K deficiency. There are very few reports of trimethoprim/sulfamethoxazole causing vitamin K deficiency and further leading to bleeding episodes. We present such a case and discuss the risk factors leading to such complications.

Racial Differences in Mortality from Severe Acute Respiratory Failure in the United States, 2008-2012.

RATIONALE: Racial disparities in health and healthcare in the United States are well documented and are increasingly recognized in acute critical illnesses such as sepsis and acute respiratory failure. OBJECTIVES: Using a large, representative, U.S. nationwide database, we examined the hypothesis that black and Hispanic patients with severe acute respiratory failure have higher mortality rates when compared with non-Hispanic whites. METHODS: This retrospective analysis used discharge data from the Agency for Healthcare Research and Quality, Nationwide Inpatient Sample, Healthcare Cost and Utilization Project, for the years 2008-2012. We identified hospitalizations with acute respiratory failure using a combination of International Classification of Diseases, Ninth Revision, Clinical Modification, codes. A logistic regression model was fitted to compare in-hospital mortality rates by race. MEASUREMENTS AND MAIN RESULTS: After adjusting for sex, age, race, disease severity, type of hospital, and median household income for patient ZIP code, blacks had a greater odds ratio of in-hospital death when compared with non-Hispanic whites (odds ratio [OR], 1.13; 95% confidence interval [CI], 1.11-1.14; P < 0.001), and Hispanics also had a greater odds ratio of in-hospital death when compared with non-Hispanic whites (OR, 1.17; 95% CI, 1.15-1.19; P < 0.001), and so did Asian and Pacific Islanders (OR, 1.15; 95% CI, 1.12-1.18; P < 0.001) and Native Americans (OR, 1.08; 95% CI, 1.00-1.15; P < 0.001) when compared with non-Hispanic whites (OR, 1.0). CONCLUSIONS: Blacks, Hispanics, and other racial minorities in the United States were observed to exhibit significantly higher in-hospital sepsis-related respiratory failure associated mortality when compared with non-Hispanic whites.

Extracorporeal Membrane Oxygenation for ARDS: National Trends in the United States 2008-2012.

INTRODUCTION: Recent advances in technology and protocols have made the use of extracorporeal membrane oxygenation (ECMO) a viable rescue therapy for patients with ARDS who present with refractory hypoxemia. Despite the lack of strong evidence supporting the use of ECMO in ARDS, its use seems to be increasing. We sought to determine recent trends in the use of ECMO for ARDS. We also assessed trends in mortality among patients with ARDS in whom ECMO was used. METHODS: We performed a retrospective analysis using the largest all-payer in-patient healthcare database in the United States, the Healthcare Cost and Utilization project, the National In-patient Sample database from 2008 to 2012. Subjects with ARDS were identified using carefully chosen International Classification of Diseases, Ninth Revision codes. RESULTS: We found that in 2008, about 1 in 1,000 subjects with ARDS underwent ECMO. Over the subsequent 4-y time period, there was a 0.19% absolute increase and 70% relative increase in the use of ECMO for ARDS. The mortality rate among subjects with ARDS in whom ECMO was used declined from 78% in 2008 to 64% in 2012. We also found a trend toward a reduction in hospital stay among survivors. CONCLUSION: In the United States, between 2008 and 2012, there was an increasing trend toward the use of ECMO in patients with ARDS that coincided with a slight increase in survival among these patients.

Fungal Endocarditis: Update on Diagnosis and Management.

Fungal endocarditis is an extremely debilitating disease associated with high morbidity and mortality. Candida spp. are the most common isolated organisms in fungal endocarditis. It is most prevalent in patients who are immunosuppressed and intravenous drug users. Most patients present with constitutional symptoms, which are indistinguishable from bacterial endocarditis, hence a high index of suspicion is required for pursuing diagnosis. Diagnosis of fungal endocarditis can be very challenging: most of the time, blood cultures are negative or take a long time to yield growth. Fungal endocarditis mandates an aggressive treatment strategy. A medical and surgical combined approach is the cornerstone of therapy.
