Performance of Febrile Infant Decision Tools on Hypothermic Infants Evaluated for Infection.

BACKGROUND: Given the lack of evidence-based guidelines for hypothermic infants, providers may be inclined to use febrile infant decision-making tools to guide management decisions. Our objective was to assess the diagnostic performance of febrile infant decision tools for identifying hypothermic infants at low risk of bacterial infection. METHODS: We conducted a secondary analysis of a retrospective cohort study of hypothermic (≤36.0 C) infants ≤90 days of age presenting to the emergency department or inpatient unit among 9 participating sites between September 1, 2016 and May 5, 2021. Well-appearing infants evaluated for bacterial infections via laboratory testing were included. Infants with complex chronic conditions or premature birth were excluded. Performance characteristics for detecting serious bacterial infection (SBI; urinary tract infection, bacteremia, bacterial meningitis) and invasive bacterial infection (IBI; bacteremia, bacterial meningitis) were calculated for each tool. RESULTS: Overall, 314 infants met the general inclusion criteria, including 14 cases of SBI (4.5%) and 7 cases of IBI (2.2%). The median age was 5 days, and 68.1% of the infants (214/314) underwent a full sepsis evaluation. The Philadelphia, Boston, IBI Score, and American Academy of Pediatrics Clinical Practice Guideline did not misclassify any SBI or IBI as low risk; however, they had low specificity and positive predictive value. Rochester and Pediatric Emergency Care Applied Research Network tools misclassified infants with bacterial infections. CONCLUSIONS: Several febrile infant decision tools were highly sensitive, minimizing missed SBIs and IBIs in hypothermic infants. However, the low specificity of these decision tools may lead to unnecessary testing, antimicrobial exposure, and hospitalization.

Uptake of community health care provision by community health entrepreneurs for febrile illness and diarrhoea: a cross-sectional survey in rural communities in Bunyangabu district, Uganda.

OBJECTIVE: To assess the uptake of services provided by community health workers who were trained as community health entrepreneurs (CHEs) for febrile illness and diarrhoea. DESIGN: A cross-sectional survey among households combined with mapping of all providers of basic medicine and primary health services in the study area. PARTICIPANTS: 1265 randomly selected households in 15 rural villages with active CHEs. SETTING: Bunyangabu district, Uganda. OUTCOME MEASURES: We describe the occurrence and care sought for fever and diarrhoea in the last 3 months by age group in the households. Care provider options included: CHE, health centre or clinic (public or private), pharmacy, drug shop and other. Geographic Information Ssystem (GIS)-based geographical measures were used to map all care providers around the active CHEs. RESULTS: Fever and diarrhoea in the last 3 months occurred most frequently in children under 5; 68% and 41.9%, respectively. For those who sought care, CHE services were used for fever among children under 5, children 5-17 and adults over 18 years of age in 34.7%, 29.9% and 25.1%, respectively. For diarrhoea among children under 5, children 5-17 and adults over 18 years of age, CHE services were used in 22.1%, 19.5% and 7.0%, respectively. For those who did not seek care from a CHE (only), drug shops were most frequently used services for both fever and diarrhoea, followed by health centres or private clinics. Many households used a combination of services, which was possible given the high density and diversity of providers found in the study area. CONCLUSIONS: CHEs play a considerable role in providing care in rural areas where they are active. The high density of informal drug shops and private clinics highlights the need for clarity on the de facto roles played by different providers in both the public and private sector to improve primary healthcare.

Assessment of pre-referral treatment for malaria, diarrhea, and pneumonia by rural community health workers in Southwestern Uganda: a cross-sectional study.

BACKGROUND: Pre-referral treatment aims to stabilize the child's condition before transferring them to a higher level of healthcare. This study explored pre-referral treatment for diarrhea, malaria and pneumonia in children U5. The study aims to assess pre-referral treatment practices among community health workers (CHWs) for children aged 2 to 59 months diagnosed with malaria, diarrhea, and pneumonia. METHODS: Conducted in 2023, this study employed a quantitative retrospective analysis of secondary data gathered from March 2014 to December 2018. Among the subjects, 171 patients received pre-referral treatment, serving as the foundation for categorical data analysis, presenting proportions and 95% confidence intervals across different categories. RESULTS: In this cohort, 90 (53%) of the 177 children U5 were male, and age distribution showed 39 (23%), 70 (41%), and 62 (36%) in the 2-11 months, 12-35 months, and 36-60 months categories, respectively. Rapid Diagnostic Test (RDT) malaria results indicated a negative outcome in 83(60%) and positive in 55 (40%) of cases. Symptomatically, 45 (26%) had diarrhea, 52 (30%) exhibited fast breathing, and 109 (63%) presented with fever. Furthermore, 59 (35%) displayed danger signs, while 104 (61%) sought medical attention within 24 h. CONCLUSION: The study analyzed a sample of 171 children under 5 years old to assess various characteristics and variables related to pre-referral treatment. The findings reveal notable proportions in gender distribution, age categories, RDT results, presence of diarrhea, fast breathing, fever, danger signs, and timely medical visits. The results highlight the need to strengthen pre-referral treatment interventions and enhance iCCM programs.

Febrile infants aged ≤60 days: evaluation and management in the emergency department.

Emergency clinicians frequently provide care to febrile infants aged ≤60 days in the emergency department. In these very young infants, fever may be the only presenting sign of invasive bacterial infection and, if untreated, invasive bacterial infection can lead to severe outcomes. This issue reviews newer risk-stratification tools and the 2021 American Academy of Pediatrics clinical practice guideline to provide recommendations for the evaluation and management of febrile young infants. The most recent literature assessing the risk of concomitant invasive bacterial infection with urinary tract infections or positive viral testing is also reviewed.

Physician's conceptions of the decision-making process when managing febrile infants ≤ 60 days old: a phenomenographic qualitative study.

BACKGROUND: The management of febrile infants aged ≤ 60 days and adherence to guidelines vary greatly. Our objective was to describe the process of decision-making when managing febrile infants aged ≤ 60 days and to describe the factors that influenced this decision. METHODS: We conducted 6 focus group discussions with 19 clinically active physicians in the pediatric emergency departments of 2 university hospitals in Skåne region, Sweden. We followed an inductive qualitative design, using a phenomenological approach. A second-order perspective was used, focusing on how physicians perceived the phenomenon (managing fever in infants) rather than the phenomenon itself. The transcribed interviews were analyzed using a 7-step approach. RESULTS: Performing a lumbar puncture (LP) was conceived as a complex, emotionally and mentally laden procedure and dominated the group discussions. Three central categories emerged as factors that influenced the decision-making process on whether to perform an LP: 1) a possible focus of infection that could explain the origin of the fever, 2) questioning whether the temperature at home reported by the parents was a fever, especially if it was ≤ 38.2°C, and 3) the infant's general condition and questioning the need for LP in case of well-appearing infants. Around these 3 central categories evolved 6 secondary categories that influenced the decision-making process of whether to perform an LP or not: 1) the physicians' desire to be able to trust their judgement, 2) fearing the risk of failure, 3) avoiding burdensome work, 4) taking others into account, 5) balancing guidelines and resources, and 6) seeing a need to practice and learn to perform LP. CONCLUSIONS: The difficulty and emotional load of performing an LP were important factors that influenced the decision-making process regarding whether to perform an LP. Physicians highlighted the importance of being able to rely on their clinical judgment and make independent decisions. Guidelines may consider allowing a degree of flexibility and independent thinking to take into account patients' characteristics and needs.

Protocol for fever control using external cooling in mechanically ventilated patients with septic shock: SEPSISCOOL II randomised controlled trial.

INTRODUCTION: Fever treatment is commonly applied in patients with sepsis but its impact on survival remains undetermined. Patients with respiratory and haemodynamic failure are at the highest risk for not tolerating the metabolic cost of fever. However, fever can help to control infection. Treating fever with paracetamol has been shown to be less effective than cooling. In the SEPSISCOOL pilot study, active fever control by external cooling improved organ failure recovery and early survival. The main objective of this confirmatory trial is to assess whether fever control at normothermia can improve the evolution of organ failure and mortality at day 60 of febrile patients with septic shock. This study will compare two strategies within the first 48 hours of septic shock: treatment of fever with cooling or no treatment of fever. METHODS AND ANALYSIS: SEPSISCOOL II is a pragmatic, investigator-initiated, adaptive, multicentre, open-label, randomised controlled, superiority trial in patients admitted to the intensive care unit with febrile septic shock. After stratification based on the acute respiratory distress syndrome status, patients will be randomised between two arms: (1) cooling and (2) no cooling. The primary endpoint is mortality at day 60 after randomisation. The secondary endpoints include the evolution of organ failure, early mortality and tolerance. The target sample size is 820 patients. ETHICS AND DISSEMINATION: The study is funded by the French health ministry and was approved by the ethics committee CPP Nord Ouest II (Amiens, France). The results will be submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT04494074.

Delays in seeking treatment for fever in children under five years of age in Nigeria: Evidence from the National Demographic Health Survey.

BACKGROUND: In countries with high child mortality rates, such as Nigeria, early intervention for common childhood illnesses (e.g., pneumonia and malaria) is essential for improving clinical outcomes. The timely reporting and treatment of fever is therefore critical in making a differential diagnosis and choosing an appropriate course of treatment. The present study aimed to investigate the prevalence and major risk factors associated with delays in seeking treatment for fever in children under five years of age in Nigeria. METHODS: This study used a total weighted sample of 7,466 children under five years of age from the 2018 National Nigerian Demographic and Health Survey. Multivariable binary logistic regression modelling was used to investigate the association between predisposing, enabling, need, health service and community level factors, and delay in treatment-seeking for fever. RESULTS: We report the delays in seeking treatment for childhood fever that was reported by mothers in the last two weeks prior to the national survey. The prevalence for delayed treatment was 62.1% (95% confidence interval [CI]: 60.1%, 64.1%). Our findings showed that there were fewer delays in seeking treatment in children aged 24-59 months (adjusted odds ratio [aOR] = 0.79, 95% CI: 0.68, 0.93), among mothers who were formally employed (aOR = 0.84; 95% CI: 0.73, 0.96), regularly attended antenatal services (aOR = 0.76, 95%CI: 0.66, 0.88), and for those who resided in wealthier households (aOR = 0.71; 95% CI: 0.56, 0.89). Children whose mothers resided in the North-West geopolitical zone of Nigeria were less likely to delay seeking treatment for fever (aOR = 0.55; 95% CI: 0.42, 0.73). However, mothers who had an unwanted pregnancy had a higher odds of delaying treatment for childhood fever (aOR = 1.58; 95% CI: 1.05, 2.39). CONCLUSION: There were significant delays in seeking treatment for childhood fever in poorer homes found in geopolitically unstable zones of Nigeria. Mothers who were poor, unemployed, and with younger children (<12 months) often delayed seeking treatment for their febrile child. Future health promotion strategies and microenterprise schemes should target both rural and urban mothers residing in poor households. Children under 12 months of age should be a priority.

Ambulatory management of low-risk febrile neutropenia in adult oncological patients. Systematic review.

PURPOSE: Recent clinical practice guidelines have recommended ambulatory management of febrile neutropenia in patients with low risk of complications. Although some centers have begun developing management protocols for these patients, there appears to be a certain reluctance to implement them in clinical practice. Our aim is to evaluate the strengths and weaknesses of this strategy according to available evidence and to propose new lines of research. METHODS: Systematic review using a triple aim approach (efficacy, cost-effectiveness, and quality of life), drawing from literature in MEDLINE (PubMed), Embase, and Cochrane Library databases. The review includes studies that assess ambulatory management for efficacy, cost-efficiency, and quality of life. RESULTS: The search yielded 27 articles that met our inclusion criteria. CONCLUSION: In conclusion, based on current evidence, ambulatory management of febrile neutropenia is safe, more cost-effective than inpatient care, and capable of improving quality of life in oncological patients with this complication. Ambulatory care seems to be an effective alternative to hospitalization in these patients.

Applying clinical decision aids for the assessment and management of febrile infants presenting to emergency care in the UK and Ireland: Febrile Infant Diagnostic Assessment and Outcome (FIDO) Study protocol.

INTRODUCTION: Febrile infants 90 days and younger are at risk of invasive bacterial infections (bacteraemia and meningitis) and urinary tract infections. Together this is previously termed serious bacterial infection with an incidence of approximately 10-20%. The National Institute for Health and Care Excellence guidance advocates a cautious approach with most infants requiring septic screening, parenteral broad-spectrum antibiotics and hospital admission. Internationally, variations exist in the approach to febrile infants, with European and North American guidance advocating a tailored approach based on clinical features and biomarker testing. None of the available international clinical decision aids (CDAs) has been validated in the UK and Irish cohorts. The aim of the Febrile Infant Diagnostic Assessment and Outcome (FIDO) Study is to prospectively validate a range of CDAs in a UK and Irish population including CDAs that use procalcitonin testing. METHODS AND ANALYSIS: The FIDO Study is a prospective multicentre mixed-methods cohort study conducted in UK and Irish hospitals. All infants aged 90 days and younger presenting with fever or history of fever (≥38°C) are eligible for inclusion. Infants will receive standard emergency clinical care without delay. Clinical data and blood samples will be collected, and consent will be obtained at the earliest appropriate opportunity using research without prior consent methodology. The performance and cost-effectiveness of CDAs will be assessed. An embedded qualitative study will explore clinician and caregiver views on different approaches to care and perceptions of risk. ETHICS AND DISSEMINATION: This study was reviewed and approved by the Office for Research Ethics Committees Northern Ireland-Health and Social Care Research Ethics Committee B, Public Benefit and Privacy Panel for Health and Social Care Scotland, and Children's Health Ireland Research and Ethics Committee Ireland. The results of this study will be presented at academic conferences and in peer-reviewed publications. TRIAL REGISTRATION NUMBER: NCT05259683.

Parental knowledge, attitudes, and practices towards childhood fever among South-East and East Asian parents: A literature review.

AIM: The aim of this literature review was to identify, summarize, and critically appraise available empirical articles on the knowledge, attitudes, and practices towards childhood fever management among South-East and East Asian parents. DESIGN: A literature review following PRISMA. METHODS: Articles were limited to those available in the English language. Articles had to be empirical studies that used a qualitative or quantitative research design with full-text available; focus on parental knowledge, attitudes, and practices towards fever; and be published in South-East and East Asia. Searches were conducted with CINAHL, PubMed and Scopus from inception to June 2022, and eleven articles were included after removing duplicates and excluding irrelevant articles. RESULTS: Narrative synthesis was conducted according to four themes: source of fever information, knowledge level, attitudes, and practices towards childhood fever. Parents showed different fever knowledge needs and various information-seeking behaviors. A low level of fever knowledge was revealed in terms of temperature, fever causes, potential harms and influencing factors. South-East and East Asian parents mainly reported anxiety, concerns and fever phobia. Fever assessment methods and fever management strategies varied based on parents' cultural background and beliefs. CONCLUSIONS: The findings of this review highlight that inadequacy of fever knowledge and negative attitudes towards childhood fever exist in South-East and East Asian parents. Parents have diverse cultural practices during their children's febrile episodes. However, some of them conflict with current medical guidelines, as they prioritize fever and body temperature reduction. This raises questions about their effectiveness and safety. Although some of them are medically discouraged, there are others that have been proven beneficial for the symptomatic relief of childhood fever. The results indicate an urgent need to develop a cultural-sensitive educational intervention for childhood fever management among South-East and East Asian parents. Unified educational interventions are needed to address parental concerns and fever-related knowledge needs.

[Procedure after successful cardiopulmonary resuscitation-Cooling or no more cooling?] / Vorgehen nach erfolgreicher Reanimation ­ kühlen oder nicht mehr kühlen?

Approximately 84 out of 100,000 inhabitants in Europe suffer from an out of hospital cardiac arrest (OHCA) each year. The mortality after cardiac arrest (CA) is high and is particularly determined by the predominant cardiogenic shock condition and hypoxic ischemic encephalopathy. For almost two decades hypothermic temperature control was the only neuroprotective intervention recommended in guidelines for postresuscitation care; however, recently published studies failed to demonstrate any improvement in the neurological outcome with hypothermia in comparison to strict normothermia in postresuscitation treatment. According to the European Resuscitation Council (ERC) and European Society of Intensive Care Medicine (ESICM) guidelines published in 2022, unconscious adults after CA should be treated with temperature management and avoidance of fever; however, many questions remain open regarding the optimal target temperature, the cooling methods and the optimal duration. Despite these currently unanswered questions, a structured and high-quality postresuscitation care that includes a targeted temperature management should continue to be provided for all patients in the postresuscitation phase, independent of the selected target temperature. Furthermore, fever avoidance remains an important component of postresuscitation care.

[Practical approach to the patient with fever in the intensive cardiac care unit: diagnostic framework and therapy notes]. / Approccio pratico al paziente con febbre in terapia intensiva cardiologica: inquadramento diagnostico e cenni di terapia.

The management of the patient with fever in the intensive cardiac care unit begins with a thorough evaluation of the patient, particularly symptoms, clinical history and physical examination, to provide information regarding the origin of the fever. The global evaluation of the patient should be integrated with blood and microbiological tests, in particular blood culture and swab. The laboratory, microbiologic or radiologic tests could be more or less detailed and targeted depending on the type of suspected infection and clinical conditions of the patient. When therapy is necessary, it is crucial to switch, as soon as possible, from broad spectrum antibiotic therapy to antibiotic therapy based on the results of the microbiological exams. Antibiotic therapy could be associated with antipyretic and specific organ support therapy when necessary.

Interpersonal communication, cultural norms, and community perceptions associated with care-seeking for fever among children under age five in Magoé district, Mozambique.

BACKGROUND: Malaria is endemic throughout Mozambique, contributing significantly to the country's burden of disease. Prompt and effective treatment for fevers in children can limit the mortality and morbidity impacts of the disease but many children in the country are not taken for formal care when ill. Using an ideational model of behaviour, this study assesses the magnitude of the relationships for potential drivers of care-seeking, including interpersonal communication, malaria messaging, and knowledge and attitudes about malaria, with actual care-seeking behaviours for under-five children with fever in Magoé district, Mozambique. METHODS: Data on the care-seeking behaviours for fever come from a 2019 household malaria survey in Magoé district. Households were randomly selected for interview from among those with at least one child under age five and one net for every two household members. From 1621 mother-child dyads, the analytical sample consists of 300 children under age five with a fever in the 2 weeks prior to the survey. Multilevel random effects logistic regression models are estimated to test for associations between care-seeking behaviours and hypothesized behavioural determinants, including interpersonal communication (IPC), malaria messaging, ideational factors (e.g., norms, attitudes, beliefs, risk perceptions), and community characteristics. RESULTS: Overall, 18.5% of children under age five (N = 300) were reported to have fever in the previous 2 weeks and, of these, 68.5% were taken to a formal sector health care provider. Multivariate models highlight significant roles for interpersonal communication; care-seeking was highest among mothers who spoke only with friends/community members about malaria (94.0%, p < 0.001), followed by those who spoke only with their husband (78.6%, p = 0.015), relative to 63.3% who spoke with no one. Care-seeking decisions made by a child's grandmother were associated with a 25.0% point (p = 0.001) greater likelihood of seeking care relative to decisions made by the mother alone. Exposure to any malaria messaging was also positively associated with care-seeking (90.5% versus 62.7%, p < 0.001). In contrast, among all individual- and community-level ideational factors, only perceptions of self-efficacy to seek care were related to care-seeking behaviours. CONCLUSIONS: These results suggest that social and behaviour change interventions that focus on encouraging families and community members to talk about malaria and the need to promptly seek treatment for fevers in children may be particularly effective at increasing this behaviour in this and similar settings. Such messaging and IPC should consider grandmothers as a target audience, as they appear to be perceived as highly influential in care-seeking decision-making in this community.

Mortality after emergency unit fluid bolus in febrile Ugandan children.

OBJECTIVES: Pediatric fluid resuscitation in sub-Saharan Africa has traditionally occurred in inpatients. The landmark Fluid Expansion as Supportive Therapy (FEAST) trial showed fluid boluses for febrile children in this inpatient setting increased mortality. As emergency care expands in sub-Saharan Africa, fluid resuscitation increasingly occurs in the emergency unit. The objective of this study was to determine the mortality impact of emergency unit fluid resuscitation on febrile pediatric patients in Uganda. METHODS: This retrospective cohort study used data from 2012-2019 from a single emergency unit in rural Western Uganda to compare three-day mortality for febrile patients that did and did not receive fluids in the emergency unit. Propensity score matching was used to create matched cohorts. Crude and multivariable logistic regression analysis (using both complete case analysis and multiple imputation) were performed on matched and unmatched cohorts. Sensitivity analysis was done separately for patients meeting FEAST inclusion and exclusion criteria. RESULTS: The analysis included 3087 febrile patients aged 2 months to 12 years with 1,526 patients receiving fluids and 1,561 not receiving fluids. The matched cohorts each had 1,180 patients. Overall mortality was 4.0%. No significant mortality benefit or harm was shown in the crude unmatched (Odds Ratio [95% Confidence Interval] = 0.88 [0.61-1.26] or crude matched (1.00 [0.66-1.50]) cohorts. Adjusted cohort analysis (including both complete case analysis and multiple imputation) and sensitivity analysis of patients meeting FEAST inclusion and exclusion criteria all also failed to show benefit or harm. Post-hoc power calculations showed the study was powered to detect the absolute harm seen in FEAST but not the relative risk increase. CONCLUSIONS: This study's primary finding is that fluid resuscitation in the emergency unit did not significantly increase or decrease three-day mortality for febrile children in Uganda. Universally aggressive or fluid-sparing emergency unit protocols are unlikely to be best practices, and choices about fluid resuscitation should be individualized.

Triage body temperature and its influence on patients with acute myocardial infarction.

BACKGROUND: Fever can occur after acute myocardial infarction (MI). The influence of body temperature (BT) after hospital arrival on patients with acute MI has rarely been investigated. METHODS: Patients who were diagnosed with acute MI in the emergency department (ED) of a tertiary teaching hospital between 1 January 2020 and 31 December 2020 were enrolled. Based on the tympanic temperature obtained at the ED triage, patients were categorized into normothermic (35.5°C-37.5°C), hypothermic (< 35.5°C), or hyperthermic (> 37.5°C) groups. The primary outcome was in-hospital cardiac arrest (IHCA), while the secondary outcomes were adverse events. Statistical significance was set at p < 0.05. RESULTS: There were 440 enrollees; significant differences were found among the normothermic (n = 369, 83.9%), hypothermic (n = 27, 6.1%), and hyperthermic (n = 44, 10.0%) groups in the triage respiratory rate (median [IQR]) (20.0 [4.0] cycles/min versus 20.0 [4.0] versus 20.0 [7.5], p = 0.009), triage heart rate (88.0 [29.0] beats/min versus 82.0 [28.0] versus 102.5 [30.5], p < 0.001), presence of ST-elevation MI (42.0% versus 66.7% versus 31.8%, p = 0.014), need for cardiac catheterization (87.3% versus 85.2% versus 72.7%, p = 0.034), initial troponin T level (165.9 [565.2] ng/L versus 49.1 [202.0] versus 318.8 [2002.0], p = 0.002), peak troponin T level (343.8 [1405.9] ng/L versus 218.7 [2318.2] versus 832.0 [2640.8], p = 0.003), length of ICU stay (2.0 [3.0] days versus 3.0 [8.0] versus 3.0 [9.5], p = 0.006), length of hospital stay (4.0 [4.5] days versus 6.0 [15.0] versus 10.5 [10.8], p < 0.001), and infection during hospitalization (19.8% versus 29.6% versus 63.6%, p < 0.001) but not in IHCA (7.6% versus 14.8% versus 11.4%, p = 0.323) or any adverse events (50.9% versus 48.1% versus 63.6%, p = 0.258). Multivariable analysis showed no significant association of triage BT with IHCA or any major complication. CONCLUSION: Triage BT did not show a significant association with IHCA or adverse events in patients with acute MI. However, triage BT could be associated with different clinical presentations and should warrant further investigation.

Minimizing Shivering During Targeted Normothermia: Comparison Between Novel Transnasal and Surface Temperature-Modulating Devices.

BACKGROUND: Shivering is a common adverse effect of achieving and maintaining normothermia in neurocritical care patients. We compared the burden of shivering and shivering-related interventions between a novel transnasal temperature-modulating device (tnTMD) and surface cooling temperature-modulating devices (sTMDs) during the first 24 h of targeted normothermia in mechanically ventilated febrile neurocritical care patients. METHODS: This is a case-control study controlling for factors that impact shiver burden: age, sex, body surface area. All patients underwent transnasal cooling (CoolStat, KeyTech, Inc.) as part of an ongoing multicenter clinical trial (NCT03360656). Patients undergoing treatment with sTMDs were selected from consecutively treated patients during the same time period. Data collected included the following: core body temperature (every 2 h), bedside shivering assessment scale (BSAS) score (every 2 h), and administration of antishivering medication for a BSAS score > 1. Time to normothermia (≤ 37.5 °C), as well as temperature burden > 37.5 °C (°C × h), were compared between groups using Student's t-test for mean differences. The proportion of patients requiring interventions, as well as the number of interventions per patient, was compared using the χ2 test. Significance was determined based on a p value < 0.05. RESULTS: There were 10 tnTMD patients and 30 sTMD patients included in the analysis (mean age: 62 ± 4, 30% women, body surface area = 1.97 ± 0.25). There were no differences between groups in temperature at cooling initiation (tnTMD: 38.5 ± 0.2 °C vs. sTMD: 38.7 ± 0.5 °C, p = 0.3), time to ≤ 37.5 °C (tnTMD: 1.8 ± 1.5 h vs. sTMD: 2.9 ± 1.4 h, p = 0.1), or temperature burden > 37.5 (tnTMD: - 0.4 ± 1.13 °C × h vs. sTMD median [IQR]: - 0.57 ± 0.58 °C × h, p = 0.67). The number of tnTMD patients who received pharmacologic shivering interventions was lower than the number of controls (20 vs. 67%, p = 0.01). tnTMD patients also had fewer shivering interventions per patient (0 [range: 0-3] vs. 4 [range: 0-23], p < 0.001). CONCLUSIONS: A transnasal cooling approach achieved similar time to normothermia and temperature burden with less shivering than surface cooling. This approach may be a feasible option to consider for mechanically ventilated febrile neurocritical care patients.

Rio Negro Virus Infection, Bolivia, 2021.

In May 2021, an agricultural worker originally from Trementinal, Argentina, sought treatment for febrile illness in Tarija, Bolivia, where he resided at the time of illness onset. The patient tested negative for hantavirus RNA, but next-generation sequencing of a serum sample yielded a complete genome for Rio Negro virus.

A cross-sectional study on factors associated with health care seeking for acute respiratory infection and fever in children under-five in Zambia.

Introduction: mortality in under-five children remains a significant challenge in developing countries, including Zambia, where pneumonia and malaria account for twenty percent of under-five deaths. Poor health care seeking is one of the contributors to the high mortality rates. This study examined the predictors of health care seeking for acute respiratory infection (ARI) and fever among under-five children in Zambia. Methods: the study used a population based cross-sectional survey program evaluation dataset with sample size of 12,507 households from 28 districts. Binary logistic regression was used to examine the determinants of appropriate care seeking for ARI or fever, ARI, and fever. Results: the prevalence of fever or ARI in children under five was 22.9%, ARI 12.9%, and fever 13.4%. Educational status and non-participation in positive deviance hearth (PDH) were significant predictors in those with fever or ARI. Children whose household head had secondary education or higher were 4.5 times more likely to seek care than those whose household head did not have any education. Among those with ARI, educational status, women empowerment in decision-making and growth monitoring and promotion (GMP) were significant predictors while for fever only GMP was a significant predictor. Conclusion: over two thirds of caregivers sought care appropriately for fever or ARI. Only educational status and GMP were associated with more than one appropriate care seeking outcome. Through GMP services, policymakers can improve healthcare seeking behavior in children under five.

Emergency medical services utilisation among febrile children attending emergency departments across Europe: an observational multicentre study.

Children constitute 6-10% of all patients attending the emergency department (ED) by emergency medical services (EMS). However, discordant EMS use in children occurs in 37-61% with fever as an important risk factor. We aimed to describe EMS utilisation among febrile children attending European EDs. This study is part of an observational multicentre study assessing management and outcome in febrile children up to 18 years (MOFICHE) attending twelve EDs in eight European countries. Discordant EMS use was defined as the absence of markers of urgency including intermediate/high triage urgency, advanced diagnostics, treatment, and admission in children transferred by EMS. Multivariable logistic regression analyses were performed for the association between (1) EMS use and markers of urgency, and (2) patient characteristics and discordant EMS use after adjusting all analyses for the covariates age, gender, visiting hours, presenting symptoms, and ED setting. A total of 5464 (15%, range 0.1-42%) children attended the ED by EMS. Markers of urgency were more frequently present in the EMS group compared with the non-EMS group. Discordant EMS use occurred in 1601 children (29%, range 1-59%). Age and gender were not associated with discordant EMS use, whereas neurological symptoms were associated with less discordant EMS use (aOR 0.2, 95%CI 0.1-0.2), and attendance out of office hours was associated with more discordant EMS use (aOR 1.6, 95%CI 1.4-1.9). Settings with higher percentage of self-referrals to the ED had more discordant EMS use (p < 0.05).  Conclusion: There is large practice variation in EMS use in febrile children attending European EDs. Markers of urgency were more frequently present in children in the EMS group. However, discordant EMS use occurred in 29%. Further research is needed on non-medical factors influencing discordant EMS use in febrile children across Europe, so that pre-emptive strategies can be implemented. What is Known: •Children constitute around 6-10% of all patients attending the emergency department by emergency medical services. •Discordant EMS use occurs in 37-61% of all children, with fever as most common presenting symptom for discordant EMS use in children. What is New: •There is large practice variation in EMS use among febrile children across Europe with discordance EMS use occurring in 29% (range 1-59%), which was associated with attendance during out of office hours and with settings with higher percentage of self-referrals to the ED. •Future research is needed focusing on non-medical factors (socioeconomic status, parental preferences and past experience, healthcare systems, referral pathways, out of hours services provision) that influence discordant EMS use in febrile children across Europe.
