Cardiac testing of Emergency Department patients with chest pain leads to increased revascularization without reduction in admissions for acute MI
Retrospective cohort study of ED patients presenting with chest pain but without evidence of ischemia, shows that non-invasive cardiac testing of these patients lead to more coronary angiograms (92.1 per 1,000 patients) within 30 days, but no significant reduction of admissions for acute MI at 1 year (remained 7.8 per 1,000 patients tested).

Facebook star ratings and “likes” correlate with patient satisfaction scores
In a cross-sectional analysis of 136 New York State hospitals, the study found increased Facebook star ratings correlated (P less than .003) with overall increased HCAHPS (Hospital Consumer Assessment of Healthcare Providers and Systems) score (21/23 HCAHPS). HCAHPS measures also positively correlated (P less than .05) with adjusted number of “likes” on Facebook but to a lesser degree (3/21 HCAHPS). Neither star ratings nor number of “likes” correlate with Medicare spending or 30-day all-cause readmission rate.

Candida auris remains an ongoing health care facility transmission risk
Multidrug-resistant fungus Candida auris is an emerging pathogen and a transmission risk across health care facilities. From June 2016 through May 2017, 77 cases of clinical infection have been reported to the Centers for Disease Control and Prevention from seven states, though most (90%) cases are clustered in the New York City metropolitan area. Most patients had multiple medical conditions and extensive health care facility exposure. The CDC recommends contact precautions, private rooming, daily and terminal cleaning with disinfectant active against Clostridium difficile spores, and notification to receiving health care facilities about C. auris colonization or infection on transfer to help reduce the spread of C. auris throughout the United States.

Infections increase risk of idiopathic VTE
Infection and infection sites have been found to be associated with a significant increased risk of venous thromboembolism, according to results of a population-based, matched, case-control analysis of medical records covering the 13-year period 1988-2000.
Dr. Kevin P. Cohoon and his colleagues at the Mayo Clinic, Rochester, Minn., developed models using conditional logistic regression analysis to stratify the risk associated with specific infections and infection sites.
Five hundred thirteen (39.4%) cases and 189 (12.7%) controls had an infection within the previous 92 days (odds ratio, 4.5; P less than .0001). Known VTE risk factors and potentially confounding variables were used in the adjusted univariate and multivariate models, as reported in the American Journal of Medicine (2017. doi: 10.1016/j.amjmed.2017.09.015).
Dr. Cohoon and his colleagues reported that univariate analysis showed “most infection sites were strongly associated with venous thromboembolism” and the adjusted multivariate model resulted in 2.4-fold (P less than .0001) higher odds for VTE incidence, compared with uninfected controls.
Adjusted multivariate analysis ranked the odds of VTE according to specific infections. Dr. Cohoon and his colleagues reported that this modeling showed that the “highest magnitude of risk, compared with no infection, was imparted by intra-abdominal infection (OR, 18) followed by oral infection (OR, 12), systematic blood stream infection (OR, 11), lower respiratory infection such as pneumonia (OR, 3.6), and symptomatic urinary tract infection (OR, 2.2).”
The researchers concluded that their findings may allow for further refinement of inpatient VTE risk-prediction models such as the Padua prediction score and “future studies are required to assess the utility of venous thromboembolism prophylaxis among outpatients with high venous thromboembolism risk infections.”
The authors reported that they had no conflicts of interest.

Developing machines that detect disease
Smells – of skin, breath, or bodily fluids – can, in some cases, reveal the presence of disease. This fact has led researchers to try to build an odor sensor that could make a fast, reliable diagnosis, and now the field may be on the verge of a breakthrough, according to a recent article in the New York Times.
In addition to various efforts in Austria, Switzerland, and Japan, an English manufacturer – Owlstone Medical – has been making headway with an odor analysis technology. It will be part of a National Health Service trial that will test the sensor for diagnosing lung cancer. The company also is conducting a trial using urine samples to detect colon cancer; its program allows changing the software to change what disease you detect.
Meanwhile, an Israeli chemical engineer, Hossam Haick, is using similar technology, with molecular receptors that have an affinity for certain biomarkers of disease found in the breath. Artificial intelligence allows the sensors to improve with each use, and a paper published last year showed that this system could distinguish among 17 different diseases with up to 86% accuracy.
And in the United States, researchers from the Monell Chemical Senses Center and the University of Pennsylvania are working on an odor sensor that detects ovarian cancer in samples of blood plasma. They chose plasma because it is less likely than breath or urine to be affected by other factors such as diet or environmental chemicals.
These technologies could be available to doctors in 3-5 years, experts say.

Rates, predictors, and variability of interhospital transfers
Clinical question: What is the national frequency of interhospital transfers, and are there any patient or hospital factors that predict these transfers?
Background: Interhospital patient transfers may be due to the need for a specialized service, but the factors and patterns have not been well studied.
Setting: All acute care hospitals in the United States.
Synopsis: Using data from the 2013 Centers for Medicare & Medicaid Services and the 2013 American Hospital Association, this study showed that 1.5% of the 6.6 million eligible beneficiaries underwent interhospital transfer (IHT). Patient and hospital characteristics that increased the odds of IHT included age 74-85 years, nonblack race, higher comorbidity, lower diagnosis-related group weight, fewer recent hospitalizations, and hospitalization in the Northeast region of the United States. Lower case mix index was associated with increased odds of IHT. Rates of IHT remain variable, after adjusting for patient and hospital characteristics. This study was restricted to the Medicare population so did not represent all populations. IHT from the emergency room was not assessed, and those who were transferred more than once (to another hospital and back) were not included.
Bottom line: A large number of Medicare patients undergo IHT nationally, and the rate varies widely based on patient factors, geography, and other factors unrelated to patient or hospital characteristics.

Rib fracture diagnosis in the panscan era
Clinical question: Do rib fractures observed on chest CT carry the same morbidity and mortality risk as those observed in chest radiograph?
Background: Traditionally studies have shown that first and second rib fractures on chest radiograph after blunt trauma are associated with substantial morbidity and mortality. With growing frequency of CT imaging in the “panscan” era, it is unknown whether similar rib fractures found on CT carry the same meaning.
Setting: 10 level I trauma centers.
Synopsis: Data from the National Emergency X-Radiography Utilization Study showed that, of the 8,661 patients who suffered blunt trauma and received both chest radiograph and chest CT, 23.9% had rib fractures. Rib fractures were observed in 66.1% of chest CT–only cases. Patients with rib fractures had a higher admission rate (88.7% versus 45.8%) and higher mortality (5.6% versus 2.7%) than patients without rib fractures. Mortality rate and great-vessel injury were higher in those with first or second rib fractures. The mortality of patients with rib fractures observed only on chest CT was not statistically different from those whose fractures were also seen in chest radiograph. The study included patients who were more severely injured and may have been more likely to receive a CT, which may have led to an overestimation of fractures found. The actual causes of admission and death were not reviewed.
Bottom line: CT in trauma-imaging protocol can identify patients with rib fractures well, compared with combined CT with chest radiograph. Rib fractures are associated with higher rates of admission and mortality risk than those without rib fractures. Specifically, first or second rib fractures are found to have greater risk for mortality and great-vessel injury.

Mortality risks associated with emergency admission during weekends and public holidays
Clinical question: What factors contribute to increased mortality in weekend hospital admissions?
Background: The “weekend effect” is a commonly known phenomenon, where patients admitted to the hospital on weekends have higher mortality risk than those admitted on weekdays. However, little is known about the factors contributing to the excess mortality associated with weekend admissions.
Setting: Four Oxford University National Health Service hospitals in the United Kingdom (a district general hospital, a large teaching hospital, a specialist orthopedic hospital, and a major cancer center).
Synopsis: Data from the Infections in Oxfordshire Research Database of 503,938 admissions between Jan. 1, 2006, and Dec. 31, 2014 were analyzed. Thirty-day mortality was 4.7%, 5.1%, and 5.8% for patients admitted during weekdays, weekends, and public holidays, respectively (P less than .0001). Fifteen routine hematology and biochemistry test results were determined to be prognostic of high mortality risk. Adjustment for these routine test results reduced excess mortality associated with emergency admissions on weekends and public holidays. Excess mortality was notable for patients admitted on Saturdays and Sundays between 11:00 a.m. and 3:00 p.m. Hospital staffing and workload were not associated with excess mortality. The study is limited by a lack of additional patient factors such as vital signs and blood gas results that may further explain excess mortality on weekends and public holidays.
Bottom line: Patient factors, including laboratory abnormalities, rather than hospital workload and staffing may be the major contributing factors for the excess mortality seen for emergency admissions on weekends and public holidays.

Fifteen routine hematology and biochemistry test results were determined to be prognostic of high mortality risk. Adjustment for these routine test results reduced excess mortality associated with emergency admissions on weekends and public holidays. Excess mortality was notable for patients admitted on Saturdays and Sundays between 11:00 a.m. and 3:00 p.m. Hospital staffing and workload were not associated with excess mortality. The study is limited by a lack of additional patient factors such as vital signs and blood gas results that may further explain excess mortality on weekends and public holidays.
Bottom line: Patient factors, including laboratory abnormalities, rather than hospital workload and staffing may be the major contributing factors for the excess mortality seen for emergency admissions on weekends and public holidays.

Applying Choosing Wisely principles to telemetry and catheter use
The Choosing Wisely recommendations for hospitalists have launched numerous research projects. One dealing with telemetry and catheter use was published in September’s American Journal of Medicine.
After reviewing the literature on how people were implementing these recommendations, the researchers noticed most projects “1) narrowly focused on only one of the recommendations; 2) often used intrusive interventions that appeared to be burdensome and not adaptable to physician workflow; and 3) were expensive to implement,” said lead author Charlie M. Wray, DO, MS, of the Division of Hospital Medicine, San Francisco Veterans Affairs Medical Center, and the University of California, San Francisco. “We set out to design a project that could minimize these aspects while hopefully decreasing the use of telemetry and Foley catheters.”
The researchers created a “silent” reminder that was posted on a widely used screen within their EHR and was only activated when the user clicked on it. “Additionally, we wanted to make sure that this intervention made its way to teaching rounds and the patients’ bedsides,” Dr. Wray said. “So, when the attendings and residents would print out their daily census, it would contain the reminders, which allowed the team to quickly review which patients were actively using telemetry or had a Foley and discuss, at a team-level, whose telemetry or Foley could be stopped.”
The project demonstrated a trend toward less telemetry use, less time spent on telemetry, fewer catheters ordered, and more selective utilization of catheters in sicker patients.
“We believe that our project shows that the bundling of interventions has the potential to impart an effect on a greater proportion of the population than those that focus on a single issue,” Dr. Wray said. “Second, future interventions that look to utilize EHR-based clinical reminders should consider utilizing a ‘silent’ design that is prominent but doesn’t intrude upon practitioners workflow.”
You don’t need to be at a large academic institution to implement this idea, he added. “A few hours with your IT expert and a champion who is willing to take the lead could easily implement this project and hopefully see similar outcomes.”

IGRA preferred test for latent TB diagnosis
TORONTO – U.S.-based pulmonary and infectious disease specialists prefer interferon-gamma release assays (IGRA) over tuberculin skin tests (TST) for the diagnosis of latent TB infection, but may not fully understand how to use and interpret the test results, according to survey results presented at the CHEST annual meeting.
Adam G. Green, MD, conducted the research while he was a fellow in pulmonology/critical care at Montefiore Medical Center in New York. Dr. Green told attendees that about one-third of the world’s population are infected with TB and about 15 million of those live in the United States. Two-thirds of U.S. cases are seen in foreign-born individuals and are clustered in four states—New, York, California, Florida, and Texas.
Among 304 clinicians who responded to an invitation to an online questionnaire, 78% said they preferred to use IGRA over TST and 91% said they had a “good understanding” of how to use and interpret IGRA. However, when queried further on how to best use and interpret IGRAs according to current guidelines, their answers to 11 knowledge-based questions told a somewhat different story, said Dr. Green, who is an intensivist at Cooper University Health Care in Camden, N.J.
While 96% knew IGRAs are not helpful in monitoring response to TB treatment, 20% erroneously thought that a positive IGRA predicts latent TB infection reactivation in the future.
Most respondents correctly answered two “fundamental” questions on cross-reactivity of IGRAs with Mycobacterium avium complex and bacilli Calmette-Guérin (BCG) vaccination (84% and 96%, respectively). “While 80% sounds good, I think we’re talking about ID and pulmonary docs at the best institutions across the United States, so I would have expected much higher,” Dr. Green said.
Only one-third of respondents knew that the T-SPOT.TB test, an IGRA, had the highest sensitivity for identifying those with latent TB infection. And only about half were able to appropriately identify the need to initiate therapy for latent TB in a scenario in which the patient was at “high risk for latent tuberculosis with a positive tuberculin skin test and a negative interferon-gamma release assay.”
Fellows comprised 42.5% of respondents and the remainder were attendings of varying levels of seniority. About half of respondents were pulmonologists and the other half infectious disease specialists. The majority (91%) were practicing or training in university hospitals.
One major limitation of the study, said Dr. Green, is the low response rate. “I would have liked 3,000 responses,” he said, rather than just over 300.
To disseminate the questionnaire, he contacted pulmonary and infectious disease academic program directors and coordinators and asked them to forward the survey invitation to their full-time faculty and fellows. Dr. Green also acknowledged that his project missed those physicians not working in academic centers.
“I would like to think that the reason people didn’t do as well as I had hoped is because of the conflicting literature out there and using not necessarily the guidelines but rather their current knowledge on what was most recently published,” said Dr. Green. “But maybe there is a true misunderstanding.”
The authors reported there were no product or funding disclosures relevant to this study.

Taking urine samples from infants
Urinary tract infection (UTI) is one of the most common bacterial infections in young febrile infants, but doctors know that collecting a urine sample to diagnose or exclude UTI can be very challenging in practice.
Recently, researchers in Australia conducted a randomized controlled trial in a pediatric hospital emergency department to test a method that could stimulate voiding within 5 minutes. It’s called the Quick-Wee method, and the technique involves the clinician rubbing the suprapubic area of the child in a circular pattern with gauze soaked in cold saline held with disposable plastic forceps. In the trial, this was done until the sample was obtained or until 5 minutes passed.
For some young children, when a urine sample is required, a catheter or suprapubic needle aspirate sample will be indicated, he added. “But for many others, the Quick-Wee method may allow clinicians to collect a clean catch sample, and spare the need for painful and invasive procedures in some circumstances.”

VIDEO: Balanced crystalloids protect kidney better than saline
TORONTO – Treatment with balanced crystalloid IV fluids cut adverse renal events modestly but with statistical significance, compared with 0.9% saline in hospitalized patients in a pair of single-center randomized trials with more than 29,000 total patients.
Despite showing a number needed to treat with balanced crystalloids of roughly 100 to prevent one major renal event, compared with saline, the scope of IV fluid use makes even this relatively small improvement potentially important to tens of thousands of patients annually.
“It’s a small but clinically important difference,” Wesley H. Self, MD, said at the CHEST annual meeting.
“These fluids are used every day and in millions of patients annually in the United States and worldwide. There is no functional cost difference between them, and now we have the data to show that [balanced crystalloid fluids] produce a better patient outcome. It’s reasonable to consider changing practice,” based on the results, said Matthew W. Semler, MD, a pulmonologist at Vanderbilt University Medical Center in Nashville, Tenn., who led one of the two trials.
At Vanderbilt, where the two studies ran, “we’ve changed our practice and are transitioning from primarily using saline to primarily balanced crystalloid,” Dr. Semler said in a video interview. The main limitation to changing practice now because of the results is that the two trials both ran at a single center.
The findings Dr. Semler reported came from the Isotonic Solutions and Major Adverse Renal Events Trial (SMART), which randomized 7,860 ICU patients to treatment with 0.9% saline fluid and 7,942 ICU patients to treatment with balanced crystalloid fluid, either lactated Ringer’s or Plasma-Lyte A. The study’s primary endpoint was the combined 30-day rate of in-hospital death, incident need for renal replacement therapy, or at least a doubling of the patient’s baseline creatinine level, a marker of persistent renal dysfunction.
This outcome occurred in 14.3% of patients on balanced crystalloid fluid and 15.4% on saline, a 1.1% statistically significant absolute difference. The endpoint components showed that patients treated with balanced crystalloid had 0.8% less in-hospital death and 0.4% less incident renal replacement therapy; both of these between-group differences were close to having statistical significance. The two treatment groups showed less difference in the rate of persistent renal dysfunction.
The second trial had an identical design but ran instead in the emergency department. The Saline Against Lactated Ringers or Plasmalyte in the Emergency Department (SALT-ED) trial randomized 6,708 to receive balanced crystalloid and 6,639 to receive saline. The combined primary renal endpoint was 0.9% less frequent with balanced crystalloid fluid, a statistically significant difference, Dr. Self, an emergency medicine physician at Vanderbilt, reported at the meeting. In this study the between-group differences for both incident renal replacement therapy and persistent renal dysfunction were statistically significant in favor of balanced crystalloid, but the between-group mortality difference was not significantly different.
The reason why balanced crystalloid fluid produced better renal outcomes than saline remains unclear. Both Dr. Semler and Dr. Self noted that the two balanced crystalloid fluids used in the study have chloride levels that closely match normal plasma levels, but the chloride concentration in 0.9% saline is about 50% higher than plasma. Some researchers have hypothesized, based on animal findings, that this difference may influence inflammation, blood pressure, acute kidney injury, and renal vasoconstriction.
The SMART and SALT-ED trials received no commercial funding. Dr. Semler had no disclosures. Dr. Self has been a consultant to Abbott Point of Care, BioTest, Cempra, Ferring, Gilead, and Pfizer.
