Introduction: According to the International Evidence-Based Recommendations for Point-of-Care Lung Ultrasound published in 2012, the sonographic technique for evaluating a patient for a pneumothorax (PTX) “consists of exploration of the least gravitationally dependent areas progressing more laterally” in the supine patient. However, there is a wide variety of scanning protocols in the literature with varying accuracy and complexity. We sought to derive an efficient and accurate scanning protocol for diagnosing pneumothorax using point of care ultrasound in trauma. Methods: We performed a retrospective chart review of a tertiary care trauma registry from Nov 2006 to Aug 2016. We included patients with a PTX diagnosed on computed tomography (CT). Patients were excluded if they did not have an identifiable PTX on the CT scan or if they underwent a tube thoracostomy prior to the CT scan. Penetrating and blunt trauma were eligible. Data were extracted with a standardized data collection tool and 20% of charts reviewed by two reviewers. Pre defined zones were used to map area of PTXs on CT. Sensitivity, specificity and 95% CI are reported for presence of PTXs in each individual or combination of lung zones as identified on CT scan. Results: Data were collection yielded 170 traumatic PTX on chest CT with an average age of 44.2 and 77.8% male. The kappa for data extraction was 0.88. 19.4% of patients had bilateral PTX leading to a total sample size of 203. The average ISS score was 20.7 and 93% of patients survived to discharge. The length of ICU stay and hospital stay was 3.7 and 11.2 days respectively. The most accurate and efficient protocol would involve scanning the inferior border of the clavicle at the para-sternal border and again at the mid-clavicular line down to the cardiac (left hemithorax) and liver lung points (right hemithorax). The sensitivity of this scanning area in the detection of PTXs was 91.6% (95% CI 86.9-95%,). Limiting the area to the most anterior point of the chest wall increased the risk of missing a PTX (Sensitivity 89.7% (95%CI 84.6-93.5)). Conclusion: We have derived an evidence-based standardized accurate and efficient scanning protocol to rule out a pneumothorax on point of care ultrasound.

The Impact

Background: Several interventions have been shown to be effective in reducing the incidence of ventilator-associated pneumonia (VAP), but their implementation in clinical practice has not gained widespread acceptance. Objective: To determine the impact of a protocol that incorporates evidence-based interventions shown to reduce the frequency of VAP on the overall rate of VAP, early-onset VAP, and late-onset VAP in the intensive care unit (ICU) of a tertiary care adult teaching hospital. Methods: This pre- and postintervention observational study included mechanically ventilated patients admitted to the Montreal General Hospital ICU between November 2003 and May 2004 (preintervention) and between November 2004 and May 2005 (postintervention). A multidisciplinary prevention protocol was developed, implemented, and reinforced. Rates of VAP per 1000 ventilator-days were calculated pre- and postprotocol implementation for all patients, for patients with early-onset VAP, and for those with late-onset VAP. Results: In the pre- and postintervention groups, 349 and 360 patients, respectively, were mechanically ventilated. Twenty-three VAP episodes occurred in 925 ventilator-days (crude incidence rate 25 per 1000) in the preintervention period. Following implementation, the VAP rate decreased to 22 episodes in 988 ventilatordays (crude incidence rate 22.3 per 1000), corresponding to a relative reduction in rate of 10.8% (p < 0.001). The incidence of early-onset VAP decreased from 31.0 to 18.5 VAP per 1000 ventilator-days (p < 0.001), while the incidence of late-onset VAP increased from 21.9 to 24.1 VAP per 1000 ventilator-days (p < 0.001). However, when all covariates were adjusted, the impact of the prevention protocol was not statistically significant. Conclusions: Implementation of a VAP prevention protocol incorporating evidence-based interventions reduced the crude incidence of VAP, early-onset VAP, and late-onset VAP. However, when covariates were adjusted, the beneficial effect was no longer observed. Further research is needed to assess the impact of such measures on VAP, early-onset VAP, and late-onset VAP.

Lead Endocarditis

Background: Cardiac device-related endocarditis has emerged as a serious complication in the era of advanced medical technology. Pacemaker related infections are rare and life-threatening with incidence from 0.06% to 7% and high mortality rate (30-35%). Diagnosis is hard, frequently delayed and could be even missed due to poor clinical findings. The average delay in diagnosis is 5.5 month. We report a case of the late-onset of pacemaker lead endocarditis caused by S. epidermidis successfully treated with open heart surgery. Case Report: Patient with persistent high fever for 11 month and suspicion for infective endocarditis was admitted in Cardiovascular Institute. No clinical signs of endocarditis were observed. TTE revealed large vegetation 30 × 17 mm attached to the atrial electrodes with high embolic potential. This finding was verified by transesophageal echocardiography (TEE), although CT scan did not reveal vegetation. Blood cultures were negative. A sternotomy with cardiopulmonary bypass was performed and electrodes were extracted with large vegetation. Intraoperative finding revealed large thrombus with vegetation around pacemaker leads. Cultures of the electrodes and vegetation revealed Staphylococcus epidermidis. Surgery was followed up with antibiotic treatment for 6 weeks. He has been followed up for the next 2 years, and without complications. Conclusion: The absence of criteria for endocarditis and negative blood cultures should not keep the physician from ruling out lead endocarditis. This complication carries high risk of mortality if left untreated.

ObjectiveTo describe the epidemiology of neonatal infections and of antimicrobial use in Greek Neonatal Units (NNUs) in order to develop national, evidence-based guidelines on empiric antimicrobial use for neonatal sepsis in Greece.DesignRetrospective analysis of prospectively collected infection surveillance data from 2012 to 2015, together with a Point Prevalence Survey (PPS) on antimicrobial use and the collection of data on local empiric antimicrobial policies.Setting16 NNUs in Greece participating in the neonIN infection surveillance networkPatientsNewborns in participating NNUs who had a positive blood, cerebrospinal fluid or urine culture and were treated with at least 5 days of antibiotics.Results459 episodes were recorded in 418 infants. The overall incidence of infection was 50/1000 NNU-admissions. The majority of episodes were late-onset sepsis (LOS) (413, 90%). Coagulase-negative Staphylococci (80%) were the most common Gram-positive organisms causing LOS and Klebsiella spp (39%) the most common Gram-negative. Nearly half (45%) of the Klebsiella spp were resistant to at least one aminoglycoside. The PPS revealed that 196 of 484 (40%) neonates were on antimicrobials. The survey revealed wide variation in empiric antimicrobial policies for LOS.ConclusionsThis is the largest collection of data on the epidemiology of neonatal infections in Greece and on neonatal antimicrobial use. It provides the background for the development of national evidence-based guidelines. Continuous surveillance, the introduction of antimicrobial stewardship interventions and evidence-based guidelines are urgently required.

Abstract Gilead et al. offer a thoughtful and much-needed treatment of abstraction. However, it fails to build on an extensive literature on abstraction, representational diversity, neurocognition, and psychopathology that provides important constraints and alternative evidence-based conceptions. We draw on conceptions in software engineering, socio-technical systems engineering, and a neurocognitive theory with abstract representations of gist at its core, fuzzy-trace theory.

Purpose Misophonia is a sound tolerance disorder condition in certain sounds that trigger intense emotional or physiological responses. While some persons may experience misophonia, a few patients suffer from misophonia. However, there is a dearth of literature on audiological assessment and management of persons with misophonia. The purpose of this report is to discuss the assessment of misophonia and highlight the management option that helped a patient with misophonia. Method A case study of a 26-year-old woman with the complaint of decreased tolerance to specific sounds affecting quality of life is reported. Audiological assessment differentiated misophonia from hyperacusis. Management included retraining counseling as well as desensitization and habituation therapy based on the principles described by P. J. Jastreboff and Jastreboff (2014). A misophonia questionnaire was administered at regular intervals to monitor the effectiveness of therapy. Results A detailed case history and audiological evaluations including pure-tone audiogram and Johnson Hyperacusis Index revealed the presence of misophonia. The patient benefitted from intervention, and the scores of the misophonia questionnaire indicated a decrease in the severity of the problem. Conclusions It is important to differentially diagnose misophonia and hyperacusis in persons with sound tolerance disorders. Retraining counseling as well as desensitization and habituation therapy can help patients who suffer from misophonia.

Purpose This study examined the current pediatric amplification practice with an emphasis on hearing aid verification using probe microphone measurement (PMM), among audiologists in Klang Valley, Malaysia. Frequency of practice, access to PMM system, practiced protocols, barriers, and perception toward the benefits of PMM were identified through a survey. Method A questionnaire was distributed to and filled in by the audiologists who provided pediatric amplification service in Klang Valley, Malaysia. One hundred eight ( N = 108) audiologists, composed of 90.3% women and 9.7% men (age range: 23–48 years), participated in the survey. Results PMM was not a clinical routine practiced by a majority of the audiologists, despite its recognition as the best clinical practice that should be incorporated into protocols for fitting hearing aids in children. Variations in practice existed warranting further steps to improve the current practice for children with hearing impairment. The lack of access to PMM equipment was 1 major barrier for the audiologists to practice real-ear verification. Practitioners' characteristics such as time constraints, low confidence, and knowledge levels were also identified as barriers that impede the uptake of the evidence-based practice. Conclusions The implementation of PMM in clinical practice remains a challenge to the audiology profession. A knowledge-transfer approach that takes into consideration the barriers and involves effective collaboration or engagement between the knowledge providers and potential stakeholders is required to promote the clinical application of evidence-based best practice.

Ebp Implementation

Purpose The current investigation is a follow-up from a previous study examining child language diagnostic decision making in school-based speech-language pathologists (SLPs). The purpose of this study was to examine the SLPs' perspectives regarding the use of evidence-based practice (EBP) in their clinical work. Method Semistructured phone interviews were conducted with 25 school-based SLPs who previously participated in an earlier study by Fulcher-Rood et al. 2018). SLPs were asked questions regarding their definition of EBP, the value of research evidence, contexts in which they implement scientific literature in clinical practice, and the barriers to implementing EBP. Results SLPs' definitions of EBP differed from current definitions, in that SLPs only included the use of research findings. SLPs seem to discuss EBP as it relates to treatment and not assessment. Reported barriers to EBP implementation were insufficient time, limited funding, and restrictions from their employment setting. SLPs found it difficult to translate research findings to clinical practice. SLPs implemented external research evidence when they did not have enough clinical expertise regarding a specific client or when they needed scientific evidence to support a strategy they used. Conclusions SLPs appear to use EBP for specific reasons and not for every clinical decision they make. In addition, SLPs rely on EBP for treatment decisions and not for assessment decisions. Educational systems potentially present other challenges that need to be considered for EBP implementation. Considerations for implementation science and the research-to-practice gap are discussed.
