National Survey on the Impact of Viral Testing for the ED and Inpatient Management of Febrile Young Infants

Provision of Adolescent Confidential Care in a Pediatric Tertiary Care Hospital

PURPOSE

Adolescents are more likely to disclose sensitive health information if confidentiality is assured. We sought to evaluate the frequency, quality, and factors associated with provision of confidential care to adolescent patients at a pediatric teaching hospital.

METHODS

We undertook a cross-sectional survey of adolescents presenting to a tertiary pediatric hospital from January 2019 to January 2020. A convenience sample of adolescents eligible for confidential care under Quebec legislation (aged 14-18 years) were surveyed either following their emergency department (ED) or inpatient care. Participants completed a self-administered electronic questionnaire regarding the confidential care provided at their initial ED or inpatient medical encounter. Multivariable logistic regression was used to identify factors associated with the provision of confidential care.

RESULTS

Overall, 406 adolescents completed the survey (335 ED; 71 inpatient); 137 (33.7%) endorsed being offered and 95 (69%) accepted confidential time. Among adolescents receiving confidential care, 43% reported that the limits of confidentiality were reviewed and 23% reported that private issues were still discussed in front of family members. Multivariable analysis revealed inpatient setting (adjusted odds ratio [aOR] 2.28, 1.04-5.01), female gender (aOR 2.02, 1.21-3.38), age (aOR 1.67, 1.03-2.69), psychiatric diagnosis (aOR 8.10, 1.47-44.6), resident involvement (aOR 1.96, I.09-3.53) were all positively associated with the provision of confidential care.

DISCUSSION

Survey results suggest inadequate provision of confidential care in an academic pediatric hospital. The limits of confidentiality were not consistently explained, and breaches in confidentiality were not infrequent. Confidentiality-specific education initiatives are necessary to improve the frequency and quality of confidential care for adolescents in tertiary care settings.

Trends in Respiratory Viral Testing in Pediatric Emergency Departments Following the COVID-19 Pandemic

STUDY OBJECTIVE

To evaluate for increases in the use and costs of respiratory viral testing in pediatric emergency departments (EDs) because of the COVID-19 pandemic.

METHODS

We performed a cross-sectional study using the pediatric health information system. Eligible subjects were children (90 days to 18 years) who were discharged from a pediatric ED and included in the pediatric health information system from October 2016 through March 2024. To evaluate for changes in the frequency and costs of respiratory viral testing, we performed an interrupted time series analysis across 3 study periods: prepandemic (October 1, 2016 to March 14, 2020), early pandemic (March 15, 2020 to December 31, 2023), and late pandemic (January 1, 2023 to March 31, 2024).

RESULTS

We included 15,261,939 encounters from 34 pediatric EDs over the 90-month study period. At least 1 viral respiratory test was performed for 460,826 of 7,311,177 prepandemic encounters (6.3%), 1,240,807 of 5,100,796 early pandemic encounters (24.3%), and 545,696 of 2,849,966 late pandemic encounters (19.1%). There was a positive prepandemic slope in viral testing (0.17% encounters/month; 95% CI 0.17 to 0.18). The early pandemic was associated with a shift change of 4.98% (95% CI 4.90 to 5.07) and a positive slope (0.54% encounters/month; 95% CI 0.54 to 0.55). The late pandemic period was associated with a negative shift (-17.80%; 95% CI -17.90 to -17.70) and a positive slope (0.42% encounters/month; 95% CI 0.41 to 0.42). The slope in testing costs increased from $5,000/month (95% CI $4,200 to $5,700) to $33,000/month (95% CI $32,000 to $34,000) during the early pandemic.

CONCLUSION

Respiratory testing and associated costs increased during the COVID-19 pandemic and were sustained despite decreasing incidence of disease. These findings highlight a need for further efforts to clarify indications for viral testing in the ED and efforts to reduce low-value testing.

National Survey on the Emergency Department Management of Febrile Infants 29 to 60 Days Old With an Abnormal Urinalysis

OBJECTIVES

Recent clinical practice guidelines recommend that decisions regarding lumbar puncture (LP) for febrile infants older than 28 days should no longer be based on urinalysis results, but rather independently determined by inflammatory markers and sometimes guided by shared decision-making (SDM). This study sought to assess management decisions for febrile infants aged 29 to 60 days with an abnormal urinalysis.

METHODS

A scenario-based survey was sent to emergency department physicians at all 15 Canadian tertiary pediatric centers. Participants were asked questions regarding management decisions when presented with a well-appearing febrile infant in the second month of life with either an abnormal or normal urinalysis.

RESULTS

Response rate was 50.2% (n = 116/231). Overall, few respondents would perform an LP based on either an abnormal or normal urinalysis alone (10.3% and 6.0%, respectively). However, regression analysis demonstrated that decisions regarding LP were influenced by urinalysis results ( P < 0.001), with respondents more likely to defer to inflammatory marker results for infants with a normal urinalysis result (57.8%) compared with those with an abnormal urinalysis (28.4%). Hospitalization (62.1%) and empiric antibiotic treatment by intravenous route (87.9%) were both frequent for low-risk infants with an abnormal urinalysis. Nearly half of respondents reported rarely (<25% of encounters) engaging families in SDM regarding LP decisions.

CONCLUSIONS

Knowledge translation initiatives reflecting current evidence should target use of inflammatory markers rather than urinalysis results to guide decisions regarding LP. Efforts emphasizing outpatient management with oral antibiotics and SDM for low-risk infants with an abnormal urinalysis could also further align management with current evidence and guidelines.

La prise en charge des nourrissons de 90 jours ou moins, fiévreux mais dans un bon état général

On constate des pratiques très variées en matière d'évaluation et de prise en charge des jeunes nourrissons fiévreux. Bien que la plupart des jeunes nourrissons fiévreux mais dans un bon état général soient atteints d'une maladie virale, il est essentiel de détecter ceux qui sont à risque de présenter des infections bactériennes invasives, notamment une bactériémie et une méningite bactérienne. Le présent document de principes porte sur les nourrissons de 90 jours ou moins dont la température rectale est de 38,0 °C ou plus, mais qui semblent être dans un bon état général. Il est conseillé d'appliquer les récents critères de stratification du risque pour orienter la prise en charge, ainsi que d'intégrer la procalcitonine à l'évaluation diagnostique. Les décisions sur la prise en charge des nourrissons qui satisfont aux critères de faible risque devraient refléter la probabilité d'une maladie, tenir compte de l'équilibre entre les risques et les préjudices potentiels et faire participer les parents ou les proches aux décisions lorsque diverses options sont possibles. La prise en charge optimale peut également dépendre de considérations pragmatiques, telles que l'accès à des examens diagnostiques, à des unités d'observation, à des soins tertiaires et à un suivi. Des éléments particuliers, tels que la mesure de la température, le risque d'infection invasive à Herpes simplex et la fièvre postvaccinale, sont également abordés.

Management of well-appearing febrile young infants aged ≤90 days

The evaluation and management of young infants presenting with fever remains an area of significant practice variation. While most well-appearing febrile young infants have a viral illness, identifying those at risk for invasive bacterial infections, specifically bacteremia and bacterial meningitis, is critical. This statement considers infants aged ≤90 days who present with a rectal temperature ≥38.0°C but appear well otherwise. Applying recent risk-stratification criteria to guide management and incorporating diagnostic testing with procalcitonin are advised. Management decisions for infants meeting low-risk criteria should reflect the probability of disease, consider the balance of risks and potential harm, and include parents/caregivers in shared decision-making when options exist. Optimal management may also be influenced by pragmatic considerations, such as access to diagnostic investigations, observation units, tertiary care, and follow-up. Special considerations such as temperature measurement, risk for invasive herpes simplex infection, and post-immunization fever are also discussed.

Perceived barriers to the provision of adolescent confidential care in a tertiary care setting

Objective

Adolescents are more likely to seek care and disclose sensitive health information if confidentiality is assured. Little is known regarding the provision of confidential care to adolescents in the hospital setting. We sought to understand confidentiality practices and barriers for adolescents cared for in a tertiary hospital setting.

Methods

This was a cross-sectional survey of all Emergency Department (ED), hospitalist, and resident physicians at a tertiary paediatric hospital from May/2019 to July/2019. Participants were asked multiple choice questions regarding practices, comfort, and barriers to confidential care.

Results

Response rate was 91% (n = 72/79; 26 ED, 14 hospitalists, 32 residents). Overall, 47% of respondents doubted that confidential care was being consistently provided to adolescents. Fifty-eight per cent of attendings and 31% of residents reported usually/always offering confidential care. Factors most reported to influence the provision of confidential care were chief complaint (75%), time of visit (45%), and patient age (25%). Barriers to the quantity or quality of confidential care were identified by 89%, most commonly including time constraints (21%), perceived parental resistance (26%), lack of private space (26%), and the belief that confidentiality is not necessary for all adolescent encounters (34%). Forty per cent of respondents reported breaching confidentially and discussing sensitive topics with adolescents in front of family members. Overall, only 45% felt they had received adequate training on how best to deliver confidential care, and 75% reported a desire for additional training.

Conclusion

Results suggest inadequate provision of confidential care in a tertiary teaching hospital, with several potentially modifiable barriers.

Management of Pediatric Post-Concussion Headaches: National Survey of Abortive Therapies Used in the Emergency Department

Children frequently present to an Emergency Department (ED) after concussion, and headache is the most commonly associated symptom. Recent guidelines emphasize the importance of analgesia for post-concussion headache (PCH), yet evidence to inform treatment is lacking. We sought to characterize abortive therapies used to manage refractory PCH in the pediatric ED and factors associated with treatment. A scenario-based survey was distributed to ED physicians at all 15 Canadian tertiary pediatric centers. Participants were asked questions regarding ED treatment of acute (48 h) and persistent (1 month) PCH refractory to appropriate doses of acetaminophen/ibuprofen. Logistic regression was used to assess factors associated with treatment. Response rate was 63% (137/219). Nearly all physicians (128/137, 93%) endorsed treatment in the ED for acute PCH of severe intensity, with most selecting intravenous treatments (116/137, 84.7%). Treatments were similar for acute and persistent PCH. The most common treatments were metoclopramide (72%), physiologic saline (47%), and nonsteroidal anti-inflammatory agents (NSAIDS; 35%). Second-line ED treatments were more variable. For acute PCH of moderate intensity, overall treatment was lower (102/137, 74%; p < 0.0001), and NSAIDS (48%) were most frequently selected. In multi-variable regression analyses, no physician- or ED-level factor was associated with receiving treatment, or treatment using metoclopramide specifically. Treatment for refractory PCH in the pediatric ED is highly variable. Importantly, patients with severe PCH are most likely to receive intravenous therapies, often with metoclopramide, despite a paucity of evidence supporting these choices. Further research is urgently needed to establish the comparative effectiveness of pharmacotherapeutic treatments for children with refractory PCH.

Impact of clinical guidance and rapid molecular pathogen detection on evaluation and outcomes of febrile or hypothermic infants

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.

Implementation of Febrile Infant Management Guidelines Reduces Hospitalization

Supplemental Digital Content is available in the text.

The clinical management of well-appearing febrile infants 7−60 days of age remains variable due in part to multiple criteria differentiating the risk of a serious bacterial infection. The purpose of this quality improvement study was to standardize risk stratification in the emergency department and length of stay in the inpatient unit by implementing an evidence-based clinical practice guideline (CPG).

Evaluating the Impact of Implementing a Clinical Practice Guideline for Febrile Infants With Positive Respiratory Syncytial Virus or Enterovirus Testing

OBJECTIVES

To evaluate clinical practice patterns and patient outcomes among febrile low-risk infants with respiratory syncytial virus (RSV) infection or enterovirus (EV) meningitis after implementing a clinical practice guideline (CPG) that provides recommendations for managing febrile infants with RSV infection and EV meningitis.

METHODS

Our institution implemented a CPG for febrile infants, which gives explicit recommendations for managing both RSV-positive and EV-positive infants in 2011. We retrospectively analyzed medical records of febrile infants ≤60 days old from June 2008 to January 2013. Among 134 low-risk RSV-positive infants, we compared the proportion of infants who underwent lumbar puncture (LP), the proportion of infants who received antibiotics, antibiotic hours of therapy (HOT), and length of stay (LOS) pre- and post-CPG implementation. Among 274 low-risk infants with EV meningitis, we compared HOT and LOS pre- and post-CPG implementation.

RESULTS

Among low-risk RSV-positive patients, the proportion of infants undergoing LP, the proportion of infants receiving antibiotics, HOT, and LOS were unchanged post-CPG. Among low-risk infants with EV meningitis, HOT (79 hours pre-CPG implementation versus 46 hours post-CPG implementation, P < .001) and LOS (47 hours pre-CPG implementation versus 43 hours post-CPG implementation, P = .01) both decreased post-CPG.

CONCLUSIONS

CPG implementation is associated with decreased antibiotic exposure and hospital LOS among low-risk infants with EV meningitis; however, there were no associated changes in the proportion of infants undergoing LP, antibiotic exposure, or LOS among low-risk infants with RSV. Further studies are needed to determine specific barriers and facilitators to effectively incorporate diagnostic viral testing into medical decision-making for these infants.

The Risk of Serious Bacterial Infection in Febrile Infants 0-90 Days of Life With a Respiratory Viral Infection

BACKGROUND

Molecular diagnostic methods enhance the sensitivity and broaden the spectrum of detectable respiratory viruses in febrile infants ≤90 days of life. We describe the occurrence of respiratory viruses in this population, as well as the rates of serious bacterial infection (SBI) and respiratory viral coinfection with regard to viral characteristics.

METHODS

This was a prospective observational cohort study performed in the emergency department that included previously healthy febrile infants ≤90 days of life. Clinical and historical characteristics were documented, and a respiratory nasal wash specimen was obtained from each patient. This sample was tested for 17 common respiratory pathogens, and a chart review was conducted to ascertain whether the infant was diagnosed with an SBI.

RESULTS

In a 12-month period, 67% of the 104 recruited febrile infants were positive for a respiratory virus. The most commonly detected viruses were rhinovirus, respiratory syncytial virus, enterovirus and influenza. The rate of respiratory viral and SBI coinfection was 9% overall, and infants with either a systemic respiratory virus or negative viral testing were 3 times more likely to have an SBI than those with viruses typically restricted to the respiratory mucosa (95% confidence interval: 1.1, 9.7).

CONCLUSIONS

Respiratory viruses are readily detectable via nasopharyngeal wash in febrile infants ≤90 days of life. With the enhanced sensitivity of molecular respiratory diagnostics, rates of coinfection of respiratory viruses and SBI may be higher than previously thought. Further investigation utilizing molecular diagnostics is needed to guide usage in febrile infants ≤90 days.

Risk of Bacterial Coinfections in Febrile Infants 60 Days Old and Younger with Documented Viral Infections

OBJECTIVE

To determine the risk of serious bacterial infections (SBIs) in young febrile infants with and without viral infections.

STUDY DESIGN

Planned secondary analyses of a prospective observational study of febrile infants 60 days of age or younger evaluated at 1 of 26 emergency departments who did not have clinical sepsis or an identifiable site of bacterial infection. We compared patient demographics, clinical, and laboratory findings, and prevalence of SBIs between virus-positive and virus-negative infants.

RESULTS

Of the 4778 enrolled infants, 2945 (61.6%) had viral testing performed, of whom 1200 (48.1%) were virus positive; 44 of the 1200 had SBIs (3.7%; 95% CI, 2.7%-4.9%). Of the 1745 virus-negative infants, 222 had SBIs (12.7%; 95% CI, 11.2%-14.4%). Rates of specific SBIs in the virus-positive group vs the virus-negative group were: UTIs (33 of 1200 [2.8%; 95% CI, 1.9%-3.8%] vs 186 of 1745 [10.7%; 95% CI, 9.2%-12.2%]) and bacteremia (9 of 1199 [0.8%; 95% CI, 0.3%-1.4%] vs 50 of 1743 [2.9%; 95% CI, 2.1%-3.8%]). The rate of bacterial meningitis tended to be lower in the virus-positive group (0.4%) than in the viral-negative group (0.8%); the difference was not statistically significant. Negative viral status (aOR, 3.2; 95% CI, 2.3-4.6), was significantly associated with SBI in multivariable analysis.

CONCLUSIONS

Febrile infants ≤60 days of age with viral infections are at significantly lower, but non-negligible risk for SBIs, including bacteremia and bacterial meningitis.

Emergency department and inpatient clinical decision tools for the management of febrile young infants among tertiary paediatric centres across Canada

Objectives

With no nationally-endorsed guidelines and the emergence of newer diagnostic tools, there exists significant variation in the management of febrile infants <90 days. We sought to evaluate the prevalence and content of clinical decision tools (CDTs) for the emergency department (ED) and inpatient management of febrile young infants across Canada.

Methods

We undertook a cross-sectional analysis of febrile young infant CDTs from ED and inpatient units at all 16 Canadian tertiary paediatric hospitals. Additional data were collected using an electronic survey of ED and inpatient representatives, characterizing their clinical settings and diagnostic test availability. Content of all existent CDTs was independently reviewed using list items determined a priori. The primary outcome was the proportion of EDs and inpatient units with CDTs.

Results

Information regarding CDTs was gathered from all 16 EDs and 16 inpatient units. CDTs were infrequently available (9/32, 28%), and were more common in the ED than inpatient setting (8/16 versus 1/16, P=0.02). Review of existing CDTs revealed inter-centre differences for inclusion ages, treatment regimens, lumbar puncture recommendations, diagnostic testing and normal laboratory values. Despite availability reported at nearly all centres, C-reactive protein and respiratory virus testing were recommended in 3/9 and 5/9 CDTs, respectively. Procalcitonin testing was available at only 2/16 (13%) centres, and not incorporated into any CDTs.

Conclusions

CDTs for the management of febrile young infants are infrequently available among Canadian tertiary paediatric centres, and rarely incorporate newer diagnostic tests. Heterogeneity among existent CDTs highlights the need for evidence-based unified ED and inpatient national guidelines.
