Factors associated with tracheostomy-associated infection treatment: A multicenter observational study. Pediatr Pulmonol 2024. [PMID: 38860585 DOI: 10.1002/ppul.27117] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 05/17/2024] [Accepted: 05/28/2024] [Indexed: 06/12/2024]
Abstract
OBJECTIVE To characterize factors that influence the decision to treat suspected pediatric bacterial tracheostomy-associated respiratory infections (bTRAINs; e.g., pneumonia, tracheitis). METHODS We conducted a multicenter, prospective cohort study of children with pre-existing tracheostomy hospitalized at six children's hospitals for a suspected bTRAIN (receipt of respiratory culture plus ≥1 doses of an antibiotic within 48 h). The primary predictor was respiratory culture growth categorized as Pseudomonas aeruginosa, P. aeruginosa + ≥1 other bacterium, other bacteria alone, or normal flora/no growth. Our primary outcome was bTRAIN treatment with a complete course of antibiotics as documented by the discharge team. We used logistic regression with generalized estimating equations to identify the association between our primary predictor and outcome and to identify demographic, clinical, and diagnostic testing factors associated with treatment. RESULTS Of the 440 admissions among 289 patients meeting inclusion criteria, 307 (69.8%) had positive respiratory culture growth. Overall, 237 (53.9%) of admissions resulted in bTRAIN treatment. Relative to a negative culture, a culture positive for P. aeruginosa plus ≥1 other organism (adjusted odds ratio [aOR] 2.3; 95% confidence interval [CI] 1.02-5.0)] or ≥1 other organism alone (aOR: 2.8; 95% CI: 1.4-5.6)] was associated with treatment. Several clinical and diagnostic testing (respiratory Gram-stain and chest radiograph) findings were also associated with treatment. Positive respiratory viral testing was associated with reduced odds of treatment (aOR: 0.5; 95% CI: 0.2-0.9). CONCLUSIONS Positive respiratory cultures as well as clinical indicators of acute illness and nonculture test results were associated with bTRAIN treatment. Clinicians may be more comfortable withholding antibiotics when a virus is identified during testing.

Provider-ordered viral testing and antibiotic administration practices among children with acute respiratory infections across healthcare settings in Nashville, Tennessee. ANTIMICROBIAL STEWARDSHIP & HEALTHCARE EPIDEMIOLOGY : ASHE 2024; 4:e29. [PMID: 38500720 PMCID: PMC10945942 DOI: 10.1017/ash.2024.24] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Revised: 01/22/2024] [Accepted: 01/25/2024] [Indexed: 03/20/2024]
Abstract
Objective Evaluate the association between provider-ordered viral testing and antibiotic treatment practices among children discharged from an ED or hospitalized with an acute respiratory infection (ARI). Design Active, prospective ARI surveillance study from November 2017 to February 2020. Setting Pediatric hospital and emergency department in Nashville, Tennessee. Participants Children 30 days to 17 years old seeking medical care for fever and/or respiratory symptoms. Methods Antibiotics prescribed during the child's ED visit or administered during hospitalization were categorized into (1) None administered; (2) Narrow-spectrum; and (3) Broad-spectrum. Setting-specific models were built using unconditional polytomous logistic regression with robust sandwich estimators to estimate the adjusted odds ratios and 95% confidence intervals between provider-ordered viral testing (ie, tested versus not tested) and viral test result (ie, positive test versus not tested and negative test versus not tested) and three-level antibiotic administration. Results 4,107 children were enrolled and tested, of which 2,616 (64%) were seen in the ED and 1,491 (36%) were hospitalized. In the ED, children who received a provider-ordered viral test had 25% decreased odds (aOR: 0.75; 95% CI: 0.54, 0.98) of receiving a narrow-spectrum antibiotic during their visit than those without testing. In the inpatient setting, children with a negative provider-ordered viral test had 57% increased odds (aOR: 1.57; 95% CI: 1.01, 2.44) of being administered a broad-spectrum antibiotic compared to children without testing. Conclusions In our study, the impact of provider-ordered viral testing on antibiotic practices differed by setting. Additional studies evaluating the influence of viral testing on antibiotic stewardship and antibiotic prescribing practices are needed.

[PMID: 37201680 PMCID: PMC10186845 DOI: 10.1016/j.jpeds.2023.113491] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 05/04/2023] [Accepted: 05/10/2023] [Indexed: 05/20/2023]
Abstract
OBJECTIVE To compare demographic characteristics, clinical features, and outcomes of children hospitalized with respiratory syncytial virus (RSV), influenza, or severe acute respiratory syndrome coronavirus 2 during their cocirculation 2021-2022 respiratory virus season. METHODS We conducted a retrospective cohort study using Colorado's hospital respiratory surveillance data comparing coronavirus disease 2019 (COVID-19)-, influenza-, and RSV-hospitalized cases < 18 years of age admitted and undergoing standardized molecular testing between October 1, 2021, and April 30, 2022. Multivariable log-binomial regression modeling evaluated associations between pathogen type and diagnosis, intensive care unit admission, hospital length of stay, and highest level of respiratory support received. RESULTS Among 847 hospitalized cases, 490 (57.9%) were RSV associated, 306 (36.1%) were COVID-19 associated, and 51 (6%) were influenza associated. Most RSV cases were <4 years of age (92.9%), whereas influenza hospitalizations were observed in older children. RSV cases were more likely to require oxygen support higher than nasal cannula compared with COVID-19 and influenza cases (P < .0001), although COVID-19 cases were more likely to require invasive mechanical ventilation than influenza and RSV cases (P < .0001). Using multivariable log-binomial regression analyses, compared with children with COVID-19, the risk of intensive care unit admission was highest among children with influenza (relative risk, 1.97; 95% CI, 1.22-3.19), whereas the risk of pneumonia, bronchiolitis, longer hospital length of stay, and need for oxygen were more likely among children with RSV. CONCLUSIONS In a season with respiratory pathogen cocirculation, children were hospitalized most commonly for RSV, were younger, and required higher oxygen support and non-invasive ventilation compared with children with influenza and COVID-19.

Abstract
Objective Pediatric patients admitted to the hospital often develop fevers during their inpatient stay, and many children are empirically started on antibiotics. The utility of respiratory viral panel (RVP) polymerase chain reaction (PCR) testing in the evaluation of nosocomial fevers in admitted patients is unclear. We sought to evaluate whether RVP testing is associated with the use of antibiotics among inpatient pediatric patients. Patients and methods We conducted a retrospective chart review of children admitted from November 2015 to June 2018. We included all patients who developed fever 48 hours or more after admission to the hospital and who were not already receiving treatment for a presumed infection (on antibiotics). Results Among 671 patients, there were 833 inpatient febrile episodes. The mean age of children was 6.3 years old, and 57.1% were boys. Out of 99 RVP samples analyzed, 22 were positive (22.2%). Antibiotics were started in 27.8% while 33.5% of patients were already on antibiotics. On multivariate logistic regression, having an RVP sent was significantly associated with increased initiation of antibiotics (aOR 95% CI 1.18-14.18, p=0.03). Furthermore, those with a positive RVP had a shorter course of antibiotics compared to those with a negative RVP (mean 6.8 vs 11.3 days, p=0.019). Conclusions Children with positive RVP had decreased antibiotic exposure compared to those with negative RVP results. RVP testing may be used to promote antibiotic stewardship among hospitalized children.

Abstract
OBJECTIVES Fever and respiratory infections are among the leading causes of pediatric emergency department visits and hospitalizations. Although typically self-resolving, clinicians may perform diagnostic tests to determine microbial etiologies of these illnesses. Although comprehensive respiratory viral panels can quickly identify causative organisms, cost to the hospital and patient may be significant. The objective of this study was to analyze the financial impact of comprehensive respiratory viral panel use in relation to associated clinical outcomes. METHODS This study was a single-center, retrospective chart review of pediatric emergency department patients who were evaluated between October 1, 2016, and April 30, 2018, with International Classification of Diseases, Tenth Revision (ICD-10) code diagnoses of acute upper respiratory infection, fever unspecified, and/or bronchiolitis. Our primary outcome was the effect of comprehensive respiratory viral panel testing and results on the total health care charge to patients. Secondary outcomes were the effect of comprehensive respiratory viral panel testing and results on emergency department length of stay and antimicrobial use. RESULTS A total of 5766 visits were included for primary analysis, with 229 (4%) undergoing comprehensive respiratory viral panel testing. Of these, 163 had a positive result (71%) for at least 1 organism. The total cost was significantly higher in the group that underwent comprehensive respiratory viral panel testing ($643.39 [$534.18-$741.15] vs $295.15 [$249.72-$353.92]; P < 0.001). There was no decrease in emergency department length of stay or significant change in antimicrobial use associated with comprehensive respiratory viral panel use. CONCLUSIONS This study demonstrates that the utilization of comprehensive respiratory viral panels in pediatric emergency department patients with bronchiolitis, unspecified fever, and/or acute upper respiratory infection adds significant cost to patient care without a decrease in their length of stay or antimicrobial use. Further studies are needed to determine the appropriate targeted use of comprehensive respiratory viral panels.

Current state and practice variation in the use of Meningitis/Encephalitis (ME) FilmArray panel in children. BMC Infect Dis 2022; 22:811. [PMCID: PMC9620602 DOI: 10.1186/s12879-022-07789-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2021] [Accepted: 10/18/2022] [Indexed: 11/10/2022] Open
Abstract
Background The Meningitis/Encephalitis FilmArray® Panel (ME panel) was approved by the U.S. Food and Drug Administration in 2015 and provides rapid results when assessing patients with suspected meningitis or encephalitis. These patients are evaluated by various subspecialties including pediatric hospital medicine (PHM), pediatric emergency medicine (PEM), pediatric infectious diseases, and pediatric intensive care unit (PICU) physicians. The objective of this study was to evaluate the current use of the ME panel and describe the provider and subspecialty practice variation. Methods We conducted an online cross-sectional survey via the American Academy of Pediatrics Section of Hospital Medicine (AAP-SOHM) ListServe, Brown University PEM ListServe, and PICU Virtual pediatric system (VPS) Listserve. Results A total of 335 participants out of an estimated 6998 ListServe subscribers responded to the survey. 68% reported currently using the ME panel at their institutions. Among test users, most reported not having institutional guidelines on test indications (75%) or interpretation (76%). 58% of providers self-reported lack of knowledge of the test’s performance characteristics. Providers from institutions that have established guidelines reported higher knowledge compared to those that did not (51% vs. 38%; p = 0.01). More PHM providers reported awareness of ME panel performance characteristics compared to PEM physicians (48% vs. 27%; p = 0.004); confidence in test interpretation was similar between both groups (72 vs. 69%; p = 0.80). Conclusion Despite the widespread use of the ME panel, few providers report having institutional guidelines on test indications or interpretation. There is an opportunity to provide knowledge and guidance about the ME panel among various pediatric subspecialties.

Abstract
Fever is one of the most common causes of medical evaluation of children, and early discrimination between viral and bacterial infection is essential to reduce inappropriate prescriptions. This study aims to systematically review the effects of point-of-care tests (POCTs) and rapid tests for respiratory tract infections on changing antibiotic prescription rate, length of stay, duration of therapy, and healthcare costs. Embase, MEDLINE, and Cochrane Library databases were systematically searched. All randomized control trials and non-randomized observational studies meeting inclusion criteria were evaluated using the NIH assessment tool. A meta-analysis was performed to assess the effects of rapid influenza diagnostic tests and film-array respiratory panel implementation on selected outcomes. From a total of 6440 studies, 57 were eligible for the review. The analysis was stratified by setting and POCT/rapid test type. The most frequent POCTs or rapid tests implemented were the Rapid Influenza Diagnostic Test and film-array and for those types of test a separate meta-analysis assessed a significant reduction in antibiotic prescription and an improvement in oseltamivir prescription. Implementing POCTs and rapid tests to discriminate between viral and bacterial infections for respiratory pathogens is valuable for improving appropriate antimicrobial prescriptions. However, more studies are needed to assess these findings in pediatric settings.

Abstract
IMPORTANCE There is high usage of antibiotics in the emergency department (ED) for children with acute respiratory illnesses. Studies have reported decreased antibiotic use among inpatients with rapid respiratory pathogen (RRP) testing. OBJECTIVE To determine whether RRP testing leads to decreased antibiotic use and health care use among children with influenzalike illness (ILI) in an ED. DESIGN, SETTING, AND PARTICIPANTS A randomized clinical trial among children aged 1 month to 18 years presenting to an ED with ILI from December 1, 2018, to November 30, 2019, was conducted. Data were analyzed March 23, 2020, to April 2, 2021. All children received a nasopharyngeal swab for RRP testing and were randomized 1:1 to the intervention group or control group (results not given, routine clinical care). Results were available in 45 minutes. Intention-to-treat analyses and modified intention-to-treat (clinician knows results) analyses were conducted using multivariable Poisson regression. INTERVENTIONS Rapid respiratory pathogen test results given to clinicians. MAIN OUTCOMES AND MEASURES Antibiotic prescribing was the primary outcome; influenza antiviral prescribing, ED length of stay, hospital admission, and recurrent health care visits were the secondary outcomes. RESULTS Among 931 ED visits (intervention group, 452 children group and control group, 456 children after exclusion of those not meeting criteria or protocol violations), a total of 795 RRP test results (85%) were positive. The median age of the children was 2.1 years (interquartile range, 0.9-5.6 years); 509 (56%) were boys. Most children (478 [53%]) were Hispanic, 688 children (76%) received government insurance, and 314 (35%) had a high-risk medical condition. In the intention-to-treat intervention group, children were more likely to receive antibiotics (relative risk [RR], 1.3; 95% CI, 1.0-1.7), with no significant differences in antiviral prescribing, medical visits, and hospitalization. In inverse propensity-weighted modified intention-to-treat analyses, children with test results known were more likely to receive antivirals (RR, 2.6; 95% CI, 1.6-4.5) and be hospitalized (RR, 1.8; 95% CI, 1.4-2.5); there was no significant difference in antibiotic prescribing (RR, 1.1; 95% CI, 0.9-1.4). CONCLUSIONS AND RELEVANCE The use of RRP testing in the ED for ILI did not decrease antibiotic prescribing in this randomized clinical trial. There is a limited role for RRP pathogen testing in children in this setting. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT03756753.

Impact of BioFire FilmArray respiratory panel results on antibiotic days of therapy in different clinical settings. ANTIMICROBIAL STEWARDSHIP & HEALTHCARE EPIDEMIOLOGY 2021; 1:e4. [PMID: 36168499 PMCID: PMC9495546 DOI: 10.1017/ash.2021.164] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/15/2021] [Revised: 05/11/2021] [Accepted: 05/16/2021] [Indexed: 12/02/2022]
Abstract
Objective: The BioFire FilmArray Respiratory Panel (RFA) has been proposed as a tool that can aid in the timely diagnosis and treatment of respiratory tract infections but its effect on antibiotic prescribing among adult patients has varied. We evaluated the impact of RFA result on antibiotic days of therapy (DOTs) in 2 distinct cohorts: hospitalized patients and patients discharged from the emergency department (ED). Design: Retrospective cohort study. Setting: The study was conducted in 3 community hospitals in Des Moines, Iowa, from March 3 to March 16, 2019. Patients: Adults aged >18 years. Methods: Potential outcome means and average treatment effects for RFA results on antibiotic DOTs were estimated. Inverse probability of treatment weighting with regression adjustment was used. Results: We identified 243 patients each in the hospitalized and ED-discharged cohorts. Among hospitalized patients, RFA results did not affect antibiotic DOTs. Among patients discharged from the ED, we found that if all patients had had influenza detected, the average DOTs would have been 2.3 DOTs (−3.2 to −1.4) less than the average observed if all the patients had had a negative RFA (P < .0001); no differences in DOTs were observed when comparing an RFA with a noninfluenza virus detected compared to an RFA with negative results. Conclusions: The impact of RFA results on antibiotic DOTs varies by clinical setting, and reductions were observed only among patients discharged from the ED who had influenza A or B detected.

Abstract
OBJECTIVE To quantify the impact of clinical guidance and rapid respiratory and meningitis/encephalitis multiplex polymerase chain reaction (mPCR) testing on the management of infants. DESIGN Before-and-after intervention study. SETTING Tertiary-care children's hospital. PATIENTS Infants ≤90 days old presenting with fever or hypothermia to the emergency department (ED). METHODS The study spanned 3 periods: period 1, January 1, 2011, through December 31, 2014; period 2, January 1, 2015, through April 30, 2018; and period 3, May 1, 2018, through June 15, 2019. During period 1, no standardized clinical guideline had been established and no rapid pathogen testing was available. During period 2, a clinical guideline was implemented, but no rapid testing was available. During period 3, a guideline was in effect, plus mPCR testing using the BioFire FilmArray respiratory panel 2 (RP 2) and the meningitis encephalitis panel (MEP). Outcomes included antimicrobial and ancillary test utilization, length of stay (LOS), admission rate, 30-day mortality. Outcomes were compared across periods using Kruskal-Wallis and Pearson tests and interrupted time series analysis. RESULTS Overall 5,317 patients were included: 2,514 in period 1, 2,082 in period 2, and 721 in period 3. Over the entire study period, we detected reductions in the use of chest radiographs, lumbar punctures, LOS, and median antibiotic duration. After adjusting for temporal trends, we observed that the introduction of the guideline was associated with reductions in ancillary tests and lumbar punctures. Use of mPCR testing with the febrile infant clinical guideline was associated with additional reductions in ancillary testing for all patients and a higher proportion of infants 29-60 days old being managed without antibiotics. CONCLUSIONS Use of mPCR testing plus a guideline for young infant evaluation in the emergency department was associated with less antimicrobial and ancillary test utilization compared to the use of a guideline alone.

Abstract
Abstract
Background
Antibacterial agents are often prescribed for patients with suspected respiratory tract infections even though these are most often caused by viruses. In this study, we sought to evaluate the effect of Respiratory Pathogen Panel (RPP) PCR result availability and antimicrobial stewardship education on antibiotic prescription rates in the adult emergency department (ED).
Methods
We compared rates of antibacterial and oseltamivir prescriptions between 2 nonconsecutive influenza seasons among ED visits, wherein the latter season followed the implementation of a comprehensive educational stewardship campaign. In addition, we sought to elucidate the effect of RPP-PCR on antibiotic prescriptions, with focus on result availability prior to the conclusion of emergency department encounters.
Results
Antibiotic prescription rates globally decreased by 17.9% in the FS-17/18 cohort compared to FS-14/15 (P < 0.001), while oseltamivir prescription rates stayed the same overall (P = 0.42). Multivariate regression across both cohorts revealed that patients were less likely to receive antibiotics if RPP-PCR results were available before the end of the ED visit or if the RPP-PCR result was positive for influenza. Patients in the educational intervention cohort were also less likely to receive an antibiotic prescription.
Conclusion
This study provides evidence that RPP-PCR results are most helpful if available prior to the end of the provider-patient interaction. Further, these data suggest that detection of influenza remains an influential result in the context of antimicrobial treatment decision making. In addition, these data contribute to the body of literature which supports comprehensive ASP interventions including leadership and patient engagement.

Abstract
OBJECTIVE A growing body of evidence suggests that testing for influenza virus alone is more appropriate than multiplex respiratory viral panel (RVP) testing for general populations of patients with respiratory tract infections. We aimed to decrease the proportion of RVPs out of total respiratory viral testing ordered during influenza season. METHODS We implemented two consecutive interventions: reflex testing for RVPs only after a negative influenza test, and noninterruptive clinical decision support (CDS) including modifications of the computerized physician order entry search behavior and cost display. We conducted an interrupted time series of RVPs and influenza polymerase chain reaction tests pre- and postintervention, and performed a mixed-effects logistic regression analysis with a primary outcome of proportion of RVPs out of total respiratory viral tests. The primary predictor was the intervention period, and covariates included the provider, clinical setting, associated diagnoses, and influenza incidence. RESULTS From March 2013 to April 2019, there were 24,294 RVPs and 26,012 influenza tests (n = 50,306). Odds of ordering an RVP decreased during the reflex testing period (odds ratio: 0.432, 95% confidence interval: 0.397-0.469), and decreased more dramatically during the noninterruptive CDS period (odds ratio: 0.291, 95% confidence interval: 0.259-0.327). DISCUSSION The odds of ordering an RVP were 71% less with the noninterruptive CDS intervention, which projected 4,773 fewer RVPs compared with baseline. Assuming a cost equal to Medicare reimbursement rates for RVPs and influenza tests, this would generate an estimated averted cost of $1,259,474 per year. CONCLUSION Noninterruptive CDS interventions are effective in reducing unnecessary and expensive testing, and avoid typical pitfalls such as alert fatigue.

Abstract
Background Rapid diagnostic tests (RDTs) have been developed with the aim of providing accurate results in a timely manner. Despite this, studies report that provider uptake remains low. Methods We conducted a retrospective analysis of ambulatory, urgent care, and emergency department (ED) encounters at an urban safety net hospital with a primary diagnosis of an upper or lower respiratory tract infection (eg, bronchitis, pharyngitis, acute sinusitis) from January 1, 2016, to December 31, 2018. We collected RDT type and results, antibiotics prescribed, demographic and clinical patient information, and provider demographics. Results RDT use was low; a test was performed at 29.5% of the 33 494 visits. The RDT most often ordered was the rapid Group A Streptococcus (GAS) test (n = 7352), predominantly for visits with a discharge diagnosis of pharyngitis (n = 5818). Though antibiotic prescription was more likely if the test was positive (relative risk [RR], 1.68; 95% confidence interval [CI], 1.58–1.8), 92.46% of streptococcal pharyngitis cases with a negative test were prescribed an antibiotic. The Comprehensive Respiratory Panel (CRP) was ordered in 2498 visits; influenza was the most commonly detected pathogen. Physicians in the ED were most likely to order a CRP. Antibiotic prescription was lower if the CRP was not ordered compared with a negative CRP result (RR, 0.77; 95% CI, 0.7–0.84). There was no difference in prescribing by CRP result (negative vs positive). Conclusions RDTs are used infrequently in the outpatient setting, and impact on prescribing was inconsistent. Further work is needed to determine barriers to RDT use and to address potential solutions.

The effect of respiratory viral assay panel on antibiotic prescription patterns at discharge in adults admitted with mild to moderate acute exacerbation of COPD: a retrospective before- after study. BMC Pulm Med 2019; 19:118. [PMID: 31262278 PMCID: PMC6604457 DOI: 10.1186/s12890-019-0872-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2018] [Accepted: 06/10/2019] [Indexed: 11/10/2022] Open
Abstract
Background Despite well-defined criteria for use of antibiotics in patients presenting with mild to moderate Acute Exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD), their overuse is widespread. We hypothesized that following implementation of a molecular multiplex respiratory viral panel (RVP), AECOPD patients with viral infections would be more easily identified, limiting antibiotic use in this population. The primary objective of our study was to investigate if availability of the RVP decreased antibiotic prescription at discharge among patients with AECOPD. Methods This is a single center, retrospective, before (pre-RVP) - after (post-RVP) study of patients admitted to a tertiary medical center from January 2013 to March 2016. The primary outcome was antibiotic prescription at discharge. Groups were compared using univariable and multivariable logistic-regression. Results A total of 232 patient-episodes were identified, 133 following RVP introduction. Mean age was 68.1 (pre-RVP) and 68.3 (post-RVP) years respectively (p = 0.88). Patients in pre-RVP group were similar to the post-RVP group with respect to gender (p = 0.54), proportion of patients with BMI < 21(p = 0.23), positive smoking status (p = 0.19) and diagnoses of obstructive sleep apnea (OSA, p = 0.16). We found a significant reduction in antibiotic prescription rate at discharge in patients admitted with AECOPD after introduction of the respiratory viral assay (pre-RVP 77.8% vs. post-RVP 63.2%, p = 0.01). In adjusted analyses, patients in the pre-RVP group [OR 2.11 (CI: 1.13–3.96), p = 0.019] with positive gram stain in sputum [OR 4.02 (CI: 1.61–10.06), p = 0.003] had the highest odds of antibiotic prescription at discharge. Conclusions In patients presenting with mild to moderate Acute Exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD), utilization of a comprehensive respiratory viral panel can significantly decrease the rate of antibiotic prescription at discharge.

Abstract
CONTEXT Respiratory virus (RV) detection tests are commonly used in hospitalized children to diagnose viral acute respiratory infection (ARI), but their clinical utility is uncertain. OBJECTIVES To systematically review and meta-analyze the impact of RV test results on antibiotic consumption, ancillary testing, hospital length of stay, and antiviral use in children hospitalized with severe ARI. DATA SOURCES Seven medical literature databases from 1985 through January 2018 were analyzed. STUDY SELECTION Studies in children <18 years old hospitalized for severe ARI in which the clinical impact of a positive versus negative RV test result or RV testing versus no testing are compared. DATA EXTRACTION Two reviewers independently screened titles, abstracts, and full texts; extracted data; and assessed study quality. RESULTS We included 23 studies. High heterogeneity did not permit an overall meta-analysis. Subgroup analyses by age, RV test type, and viral target showed no difference in the proportion of patients receiving antibiotics between those with positive versus negative test results. Stratification by study design revealed that RV testing decreased antibiotic use in prospective cohort studies (odds ratio = 0.58; 95% confidence interval: 0.45-0.75). Pooled results revealed no conclusive impact on chest radiograph use (odds ratio = 0.71; 95% confidence interval: 0.48-1.04). Results of most studies found that positive RV test results did not impact median hospital length of stay, but they may decrease antibiotic duration. Nineteen (83%) studies were at serious risk of bias. LIMITATIONS Low-quality studies and high clinical and statistical heterogeneity were among the limitations. CONCLUSIONS Higher-quality prospective studies are needed to determine the impact of RV testing on antibiotic use in children hospitalized with severe ARI.

Abstract
Seasonal influenza virus causes significant morbidity and mortality each year. Point-of-care (POC) testing using rapid influenza diagnostic tests (RIDTs), immunoassays that detect viral antigens, are often used for diagnosis by physician offices and urgent care centers. These tests are rapid but lack sensitivity, which is estimated to be 50 to 70%. Testing by PCR is highly sensitive and specific, but historically these assays have been performed in centralized clinical laboratories necessitating specimen transport and increasing the time to result. Recently, Clinical Laboratory Improvement Amendments (CLIA)-waived, POC PCR influenza assays have been developed with >95% sensitivity and specificity compared to centralized PCR assays. To determine the clinical impact of a POC PCR test for influenza, we compared antimicrobial prescribing patterns of one urgent care location using the Cobas LIAT Influenza A/B assay (LIAT assay; Roche Diagnostics, Indianapolis, IN) to other urgent care centers in our health system using traditional RIDT, with negative specimens being reflexed to PCR. Antiviral prescribing was lower in patients with a negative LIAT PCR result (2.3%) than in patients with a negative RIDT result (25.3%; P < 0.005). Antivirals were prescribed more often in patients that tested positive by LIAT PCR (82.4%) than in those testing positive by either RIDT or reflex PCR (69.9%; P < 0.05). Antibacterial prescriptions for patients testing negative by LIAT PCR were higher (44.5%) than for those testing negative by RIDT (37.7%), although the difference was not statistically significant. In conclusion, having results from a PCR POC test during the clinic visit improved antiviral prescribing practices compared to having rapid results from an RIDT.

Abstract
This study was a retrospective analysis of inpatient and emergency department (ED) data on respiratory pathogen panel (RPP) testing between December 16, 2013, and December 15, 2015, at a mid-sized children's hospital. We assessed whether RPP decreases antibiotic days of therapy and length of hospital stay for pediatric patients with acute respiratory infections. In the inpatient population, patients testing positive with RPP were given fewer antibiotic days of therapy (2.99 vs 4.30 days; P = .032) and had shorter hospital stays (2.84 vs 3.80 days; P = .055) than patients testing negative. In the ED population, patients testing positive with RPP received fewer discharge prescriptions for antibiotics than patients not tested (8.8% vs 41.1%; P < .001). RPP use was more prevalent in admitted patients than in ED patients (78.9% vs 7.3%; P < .001). Our results suggest that RPP testing curbs antibiotic use and decreases length of hospital stay.

Abstract
Respiratory viral infections are associated with a wide range of acute syndromes and infectious disease processes in children and adults worldwide. Many viruses are implicated in these infections, and these viruses are spread largely via respiratory means between humans but also occasionally from animals to humans. This article is an American Society for Microbiology (ASM)-sponsored Practical Guidance for Clinical Microbiology (PGCM) document identifying best practices for diagnosis and characterization of viruses that cause acute respiratory infections and replaces the most recent prior version of the ASM-sponsored Cumitech 21 document, Laboratory Diagnosis of Viral Respiratory Disease, published in 1986. The scope of the original document was quite broad, with an emphasis on clinical diagnosis of a wide variety of infectious agents and laboratory focus on antigen detection and viral culture. The new PGCM document is designed to be used by laboratorians in a wide variety of diagnostic and public health microbiology/virology laboratory settings worldwide. The article provides guidance to a rapidly changing field of diagnostics and outlines the epidemiology and clinical impact of acute respiratory viral infections, including preferred methods of specimen collection and current methods for diagnosis and characterization of viral pathogens causing acute respiratory tract infections. Compared to the case in 1986, molecular techniques are now the preferred diagnostic approaches for the detection of acute respiratory viruses, and they allow for automation, high-throughput workflows, and near-patient testing. These changes require quality assurance programs to prevent laboratory contamination as well as strong preanalytical screening approaches to utilize laboratory resources appropriately. Appropriate guidance from laboratorians to stakeholders will allow for appropriate specimen collection, as well as correct test ordering that will quickly identify highly transmissible emerging pathogens.

Abstract
BACKGROUND New technologies allow rapid detecting and counting of virus genomes in clinical specimens, defining susceptibility to specific antivirals, pinpointing molecular sequences correlated to virulence traits, and identifying viral and host factors driving resolution or chronicity of infections. As a result, during the past three decades the diagnostic virology laboratory has become crucial for patient care and an integral component of the multifarious armamentarium for patient management. This change in paradigm has caused obsolescence of methods once considered the reference standard of infectious disease diagnosis that were used to detect whole or specific components of virions in the specimen. OBJECTIVES This review provides an overview of standard and novel technologies applied to molecular diagnosis of viral infections and illustrates some crucial points for correcting interpretation of the laboratory data. SOURCES Peer-reviewed literature of topics pertinent to this review. CONTENT AND IMPLICATIONS New technologies are reinventing the way virologic diagnoses are made, with a conversion to new, simpler-to-use platforms. Although indicated for the same purpose, not all methods are equal and can yield different results. Further, tests identifying multiple analytes at once can detect microorganisms present or activated as a result of pathologic processes triggered by other pathogens or noninfectious causes. Thus, new directions will have to be taken in the way in which the diagnoses of viral diseases are performed. This represents a breakthrough in the clinical virology laboratory.

Abstract
There is increasing demand for access to rapid microbiological testing, with a view to improving clinical outcomes. The possibility of rapid testing has been facilitated by development of cartridge-based random access molecular technologies that are now widely available. Whether the expense of cartridge-based assays is justified in terms of clinical or laboratory cost savings is controversial. This prospective study evaluated the impact of the Biofire FilmArray Respiratory Panel (‘FilmArray’), a cartridge-based random access molecular test, compared with standard batched molecular testing using an ‘in-house’ respiratory polymerase chain reaction (PCR) on laboratory and health service outcomes for adult patients at a tertiary-level adult hospital in Melbourne, Australia. Laboratory result turnaround time was significantly reduced with the FilmArray (median 4.4 h) compared to a standard validated in-house respiratory PCR assay (median 21.6 h, p < 0.0001) and there was a significant increase in diagnostic yield with the Filmarray (71/124, 57.3%) compared to in-house PCR (79/200; 39.5%; p = 0.002). Despite improved result turnaround time and increased diagnostic yield from testing, there was no corresponding reduction in hospital length of stay or use of isolation beds. Although cartridge-based molecular testing reduced turnaround time to result for respiratory pathogen testing, it did not impact on health service outcomes such as hospital length of stay. Further work is warranted to determine whether cartridge-based tests at the point of care can improve clinical and health service impacts.

Abstract
OBJECTIVES National guidelines recommend influenza testing for children hospitalized with influenza-like illness (ILI) during influenza season and treatment of those with confirmed influenza. Using quality improvement methods, we sought to increase influenza testing and treatment of children admitted to our hospital medicine service with ILI from 65% to 90% during the 2014-2015 influenza season. METHODS We targeted several key drivers using multiple plan-do-study-act cycles. Interventions included awareness modules, biweekly flyers, and failure tracking. ILI admissions (fever plus respiratory symptoms) were reviewed weekly once surveillance data revealed elevated influenza activity. Appropriate testing and treatment of ILI was defined as influenza testing and/or treatment within 24 hours of admission unless a known cause other than influenza was present. We used statistical process control charts to track progress using established quality improvement methods. Appropriate testing and treatment was also assessed in the 2016-2017 influenza season by using similar methods, although no new interventions were introduced. RESULTS For the 2014-2015 season, appropriate testing and treatment increased from a baseline mean of 65% to 91% within 3 months. For the 2016-2017 season, appropriate testing and treatment remained at a mean of 80% throughout the influenza season. CONCLUSIONS Appropriate influenza testing and treatment increased to 90% in children with ILI during the 2014-2015 season. Improvements were sustained in a subsequent influenza season. Our initiative improved recognition of influenza and likely increased treatment opportunities. Future work should be focused on wider implementation and further reducing variation.

Abstract
INTRODUCTION Community-acquired pneumonia (CAP) remains one of the most common reasons for paediatric morbidity and accounts for about 16% of all the deaths occurring in children less than 5 years of age. Areas covered: The main aim of this paper is to discuss the emerging problems for CAP treatment in paediatric age. Expert commentary: Official recommendations for therapeutic approaches to paediatric CAP, despite being not very recent, seem still to be the best solution to assure the highest probabilities of cure for children with this disease living in industrialized countries. Amoxicillin remains the drug of choice and use of macrolides alone or in combination does not seem supported by solid evidence. Corticosteroids can be useful in CAP associated with bronco-obstruction, whereas their effectiveness in cases with a severe inflammatory response, although plausible, is not supported by data collected through randomized, placebo-controlled trials. Finally, for the administration of vitamin C and vitamin D, the available data are not adequate to draw firm conclusions regarding the real importance of supplementation. Further studies are needed to evaluate which modifications of presently available recommendations for paediatric CAP treatment can improve final prognosis of this still common disease.

Abstract
Respiratory syndromes (RS) are among the most significant pathological conditions in edible birds and are caused by complex coactions of pathogens and environmental factors. In poultry, low pathogenic avian influenza A viruses, metapneumoviruses, infectious bronchitis virus, infectious laryngotracheitis virus, Mycoplasma spp. Escherichia coli and/or Ornithobacterium rhinotracheale in turkeys are considered as key co-infectious agents of RS. Aspergillus sp., Pasteurella multocida, Avibacterium paragallinarum or Chlamydia psittaci may also be involved in respiratory outbreaks. An innovative quantitative PCR method, based on a nanofluidic technology, has the ability to screen up to 96 samples with 96 pathogen-specific PCR primers, at the same time, in one run of real-time quantitative PCR. This platform was used for the screening of avian respiratory pathogens: 15 respiratory agents, including viruses, bacteria and fungi potentially associated with respiratory infections of poultry, were targeted. Primers were designed and validated for SYBR green real-time quantitative PCR and subsequently validated on the Biomark high throughput PCR nanofluidic platform (Fluidigm©, San Francisco, CA, USA). As a clinical assessment, tracheal swabs were sampled from turkeys showing RS and submitted to this panel assay. Beside systematic detection of E. coli, avian metapneumovirus, Mycoplasma gallisepticum and Mycoplasma synoviae were frequently detected, with distinctive co-infection patterns between French and Moroccan flocks. This proof-of-concept study illustrates the potential of such panel assays for unveiling respiratory co-infection profiles in poultry.

Clinical Utility of On-Demand Multiplex Respiratory Pathogen Testing among Adult Outpatients. J Clin Microbiol 2016; 54:2950-2955.

Abstract
Multiplex tests for respiratory tract infections include up to 20 targets for common pathogens, predominantly viruses. A specific therapeutic intervention is available for individuals testing positive for influenza viruses (oseltamivir), and it is potentially beneficial to identify non-influenza viruses to avoid unnecessary antibiotic use. We evaluated antimicrobial prescriptions following respiratory pathogen testing among outpatients at a large Veterans Administration (VA) medical center. Results of the FilmArray respiratory panel (BioFire, Salt Lake City, UT) from 15 December 2014 to 15 April 2015 were evaluated among 408 outpatients, and patient medical records were reviewed. Differences in antibiotic and oseltamivir prescription rates were analyzed. Among 408 patients tested in outpatient centers (emergency departments, urgent care clinics, and outpatient clinics), 295 (72.3%) were managed as outpatients. Among these 295 outpatients, 105 (35.6%) tested positive for influenza virus, 109 (36.9%) tested positive for a non-influenza virus pathogen, and 81 (27.5%) had no respiratory pathogen detected. Rates of oseltamivir and antibiotic prescriptions were significantly different among the three test groups (chi-squared values of 167.6 [P < 0.0001] and 10.48 [P = 0.005], respectively), but there was no significant difference in antibiotic prescription rates between the non-influenza virus pathogen group and those who tested negative (chi-square value, 0; P = 1.0). Among adult outpatients, testing positive for influenza virus was associated with receiving fewer antibiotic prescriptions, but no such effect was seen for those who tested positive for a non-influenza virus. These data suggest that testing for influenza viruses alone may be sufficient and more cost-effective than multiplex pathogen testing for outpatients.

Abstract
Community-acquired pneumonia (CAP) is the most common acute infectious cause of death in children worldwide. Consequently, research into the epidemiology, diagnosis, treatment, and prevention of pediatric CAP spans the translational research spectrum. Herein, we aim to review the most significant findings reported by investigators focused on pediatric CAP research that has been reported in 2014 and 2015. Our review focuses on several key areas relevant to the clinical management of CAP. First, we will review recent advances in the understanding of CAP epidemiology worldwide, including the role of vaccination in the prevention of pediatric CAP. We also report on the expanding role of existing and emerging diagnostic technologies in CAP classification and management, as well as advances in optimizing antimicrobial use. Finally, we will review CAP management from the policy and future endeavors standpoint, including the influence of clinical practice guidelines on clinician management and patient outcomes, and future potential research directions that are in the early stages of investigation.

Abstract
OBJECTIVE To examine whether results of a polymerase chain reaction-based respiratory viral panel (RVP) are associated with changes in antibiotic use or differential clinical outcomes among children hospitalized with pneumonia. METHODS We retrospectively identified otherwise healthy children hospitalized over a 3-year period at a single institution with community-acquired pneumonia who had an RVP performed within 24 hours of admission. We examined associations between RVP results and clinical outcomes as well as management decisions including initiation and duration of intravenous antibiotics. RESULTS Among 202 children, a positive RVP (n = 127, 63%) was associated with a more complicated clinical course, although this was due largely to more severe disease seen in younger children and those with respiratory syncytial virus (n = 38, 30% of positive detections). Detection of a virus did not influence antibiotic therapy. Included children were younger and had more severe illness than children hospitalized with pneumonia at the same institution without an RVP obtained. CONCLUSIONS In our study, only respiratory syncytial virus was associated with a more severe clinical course compared with RVP-negative children. Regardless of the virus detected, RVP positivity did not influence antibiotic usage. However, RVP use focused primarily on children with severe pneumonia. Whether similar testing influences management decisions among children with less severe illness deserves further study.
