It discusses clinical challenges in diagnosis and management, emphasising the importance of increased education and awareness among healthcare professionals. The role of empathic, person-centred care in improving patient outcomes is underscored, urging for a paradigm shift towards understanding and addressing the profound impact of myalgic encephalitis/chronic fatigue syndrome on patients' lives.

Global disease burden of and risk factors for acute lower respiratory infections caused by respiratory syncytial virus in preterm infants and young children in 2019: a systematic review and meta-analysis of aggregated and individual participant data.

BACKGROUND: Infants and young children born prematurely are at high risk of severe acute lower respiratory infection (ALRI) caused by respiratory syncytial virus (RSV). In this study, we aimed to assess the global disease burden of and risk factors for RSV-associated ALRI in infants and young children born before 37 weeks of gestation. METHODS: We conducted a systematic review and meta-analysis of aggregated data from studies published between Jan 1, 1995, and Dec 31, 2021, identified from MEDLINE, Embase, and Global Health, and individual participant data shared by the Respiratory Virus Global Epidemiology Network on respiratory infectious diseases. We estimated RSV-associated ALRI incidence in community, hospital admission, in-hospital mortality, and overall mortality among children younger than 2 years born prematurely. We conducted two-stage random-effects meta-regression analyses accounting for chronological age groups, gestational age bands (early preterm, <32 weeks gestational age [wGA], and late preterm, 32 to <37 wGA), and changes over 5-year intervals from 2000 to 2019. Using individual participant data, we assessed perinatal, sociodemographic, and household factors, and underlying medical conditions for RSV-associated ALRI incidence, hospital admission, and three severity outcome groups (longer hospital stay [>4 days], use of supplemental oxygen and mechanical ventilation, or intensive care unit admission) by estimating pooled odds ratios (ORs) through a two-stage meta-analysis (multivariate logistic regression and random-effects meta-analysis). This study is registered with PROSPERO, CRD42021269742. FINDINGS: We included 47 studies from the literature and 17 studies with individual participant-level data contributed by the participating investigators. We estimated that, in 2019, 1 650 000 (95% uncertainty range [UR] 1 350 000-1 990 000) RSV-associated ALRI episodes, 533 000 (385 000-730 000) RSV-associated hospital admissions, 3050 (1080-8620) RSV-associated in-hospital deaths, and 26 760 (11 190-46 240) RSV-attributable deaths occurred in preterm infants worldwide. Among early preterm infants, the RSV-associated ALRI incidence rate and hospitalisation rate were significantly higher (rate ratio [RR] ranging from 1·69 to 3·87 across different age groups and outcomes) than for all infants born at any gestational age. In the second year of life, early preterm infants and young children had a similar incidence rate but still a significantly higher hospitalisation rate (RR 2·26 [95% UR 1·27-3·98]) compared with all infants and young children. Although late preterm infants had RSV-associated ALRI incidence rates similar to that of all infants younger than 1 year, they had higher RSV-associated ALRI hospitalisation rate in the first 6 months (RR 1·93 [1·11-3·26]). Overall, preterm infants accounted for 25% (95% UR 16-37) of RSV-associated ALRI hospitalisations in all infants of any gestational age. RSV-associated ALRI in-hospital case fatality ratio in preterm infants was similar to all infants. The factors identified to be associated with RSV-associated ALRI incidence were mainly perinatal and sociodemographic characteristics, and factors associated with severe outcomes from infection were mainly underlying medical conditions including congenital heart disease, tracheostomy, bronchopulmonary dysplasia, chronic lung disease, or Down syndrome (with ORs ranging from 1·40 to 4·23). INTERPRETATION: Preterm infants face a disproportionately high burden of RSV-associated disease, accounting for 25% of RSV hospitalisation burden. Early preterm infants have a substantial RSV hospitalisation burden persisting into the second year of life. Preventive products for RSV can have a substantial public health impact by preventing RSV-associated ALRI and severe outcomes from infection in preterm infants.

Agitation Management in the Emergency Department with Physical Restraints: Where Do These Patients End Up?

INTRODUCTION: Agitation is frequently encountered in the emergency department (ED) and can range from psychomotor restlessness to overt aggression and violent behavior. Among all ED patients, 2.6% present with agitation or become agitated during their ED visit. We aimed to determine ED disposition for patients requiring agitation management with physical restraints. METHODS: This was a retrospective cohort of all adult patients who presented to one of 19 EDs in a large integrated healthcare system and received agitation management with physical restraints between January 1, 2018-December 31, 2020. Categorical variables are presented as frequency and percentages, and continuous variables are presented as medians and interquartile range. RESULTS: There were 3,539 patients who had agitation management with physical restraints included in this study. In total 2,076 (58.8%) were admitted to the hospital (95% CI [confidence interval] 0.572-0.605), and of those 81.4% were admitted to a primary medical floor and 18.6% were medically cleared and admitted to a psychiatric unit. Overall, 41.2% were able to be medically cleared and discharged from the ED. Mean age was 40.9 years, 2,140 were male (59.1%), 1,736 were White (50.3%), and 1,527 (43%) were Black. We found 26% had abnormal ethanol, (95% CI 0.245-0.274) and 54.6% had an abnormal toxicology screen (95% CI 0.529-0.562). A significant number were administered a benzodiazepine or antipsychotic in the ED (88.44%) (95% CI 0.874-0.895). CONCLUSION: The majority of patients who had agitation management with physical restraints were admitted to the hospital; of those patients, 81.4% were admitted to a primary medical floor and 18.6% were admitted to a psychiatric unit.

Patients utilizing emergency medical services - Does facility type matter?

BACKGROUND: Emergency departments (EDs) play a critical role in the US healthcare system. As freestanding EDs (FSEDs) are integrated into the acute care landscape, local EMS providers are transporting to these facilities, which may be closer in proximity and provide faster turnaround times. We hypothesized that patients transported via EMS to a freestanding ED required fewer tests and are admitted less frequently than those transported to a HBED. Our objective was to compare testing frequency and admission rates between patients transported via EMS to a FSED vs. HBED. METHODS: This was a retrospective cohort study of all patients who presented within a large integrated hospital system via EMS to one of 10 HBEDs or one of 6 FSEDs between April 1, 2020 - May 1, 2021. Categorical variables are presented as frequencies and percentages and comparisons between groups were obtained using chi squared tests. Continuous variables are presented as mean and standard deviation and p-values comparing groups were obtained using t-tests. Multiple logistic regression was used to assess the effect of ED type on admission status, labs ordered, and testing performed. RESULTS: A total of 123,120 encounters were included in our study. Mean age at the FSEDs was 59.9 vs. 61.3 at the HBEDs. At the FSEDs 55.6% (n = 4675) were female vs. 53.0% (n = 60,809) at the HBEDs. At the FSEDs 82.0% (n = 6805) were White vs. 60.7% (n = 68,430) at the HBEDs. We found 50.0% (n = 3974) had Medicare at the FSEDs vs 50.9% (n = 55,372) at the FSEDs. At the FSEDs, 69.5% (n = 5846) had bloodwork vs. 82.4% (n = 94,512) at the HBEDs; 68.3% (n = 5745) had an x-ray at the FSEDs vs. 70.7% (n = 81,089) at the HBEDs; 40.1% (n = 3370) had a CT scan at the FSEDs vs. 44.9% (n = 51,503) at the HBEDs; and 40.6% (n = 3412) were admitted at the FSEDs vs. 56.1% (n = 64,355) at the HBEDs. After controlling for Charlson Comorbidity Index, acuity, age, gender, sex, insurance and race, patients in FSEDs were 35% less likely to be admitted as compared to HBEDs. CONCLUSION: Patients brought in via EMS to a FSED were less likely to have blood work, x-ray, or CT scan, and were less likely to be admitted to the hospital than those transported to a HBED.

Adjusting for Case Under-Ascertainment in Estimating RSV Hospitalisation Burden of Older Adults in High-Income Countries: a Systematic Review and Modelling Study.

INTRODUCTION: Previous studies suggest diagnostic testing characteristics (i.e. variations in clinical specimens and diagnostic tests) can contribute to underestimation of RSV disease burden. We aimed to improve the understanding of RSV hospitalisation burden in older adults (aged ≥ 65 years) in high-income countries through adjusting for case under-ascertainment. METHODS: We conducted a systematic review to include data on RSV-associated acute respiratory infection (ARI) hospitalisation burden in older adults in high-income countries. To adjust for case under-ascertainment, we developed a two-step framework that incorporated empirical data on the RSV detection proportion of different clinical specimens and testing approaches as well as their statistical uncertainty. We estimated the unadjusted and adjusted RSV-associated hospitalisation burden through multilevel random-effects meta-analysis. We further explored RSV-associated in-hospital mortality burden. RESULTS: We included 12 studies with eligible RSV hospitalisation burden data. We estimated that pooled unadjusted hospitalisation rate was 157 per 100,000 (95% CI 98-252) for adults aged ≥ 65 years; the rate was adjusted to 347 per 100,000 (203-595) after accounting for under-ascertainment. The adjusted rate could be translated into 787,000 (460,000-1,347,000) RSV-associated hospitalisations in high-income countries in 2019, which was about 2.2 times the unadjusted estimate. Stratified analysis by age group showed that the adjusted rate increased with age, from 231 per 100,000 in adults aged 65-74 years to 692 per 100,000 in adults aged > 85 years. The in-hospital case fatality ratio of RSV was 6.1% (3.3-11.0) and the total RSV-associated in-hospital deaths in high-income countries in 2019 could be between 22,000 and 47,000. CONCLUSION: This study improves the understanding of RSV-associated hospitalisation burden in older adults and shows that the true RSV-associated hospitalisation burden could be 2.2 times what was reported in existing studies. This study has implications for calculating the benefit of interventions to treat and prevent RSV-associated disease.

Transversus abdominis plane (TAP) block for pain management of rectus sheath hematoma in the emergency department (ED).

Peripheral nerve blocks for pain management have historically been discussed in anesthesiology literature but, until recently, have not been considered in emergency medicine contexts. Transversus abdominis plane (TAP) blocks, in particular, have recently been explored in the emergency department for pain control in acute appendicitis but are potentially helpful for managing abdominal pain of other etiologies. One such pathology is rectus sheath hematomas, where conservative management is often necessary as curative treatments often pose more significant risks than are necessary. We report the case of a 57-year-old female presenting to the emergency department with severe abdominal pain following vigorous exercise. She was found to have a large rectus sheath hematoma on computed tomography. An ultrasound-guided transversus abdominis plane block was performed in the emergency department, and the patient had complete resolution of her pain.

Costs of management of acute respiratory infections in older adults: A systematic review and meta-analysis.

Background: Acute respiratory infections (ARIs) accounted for an estimated 3.9 million deaths worldwide in 2015, of which 56% occurred in adults aged 60 years or older. We aimed to identify the cost of ARI management in older adults (≥50 years) in order to develop an evidence base to assist decision-making for resource allocation and inform clinical practice. Methods: We searched 8 electronic databases including Global Health, Medline and EMBASE for studies published between January 1, 2000 and December 31, 2021. Total management costs per patient per ARI episode were extracted and meta-analysis was conducted by World Health Organization (WHO) region and World Bank income level. All costs were converted and inflated to Euros (€) (2021 average exchange rate). The quality of included studies and the potential risk of bias were evaluated. Results: A total of 42 publications were identified for inclusion, reporting cost data for 8 082 752 ARI episodes in older adults across 20 countries from 2001 to 2021. The majority (86%) of studies involved high-income countries based in Europe, North America and Western Pacific. The mean cost per episode was €17 803.9 for inpatient management and €128.9 for outpatient management. Compared with costs reported for patients aged &lt;65 years, inpatient costs were €154.1, €7 018.8 and €8 295.6 higher for patients aged 65-74 years, 75-84 years and over 85 years. ARI management of at-risk patients with comorbid conditions and patients requiring higher level of care, incurred substantially higher costs for hospitalization: €735.9 and €1317.3 respectively. Conclusions: ARIs impose a substantial economic burden on health systems, governments, patients and societies. This study identified high ARI management costs in older adults, reinforcing calls for investment by global health players to quantify and address the scale of the challenge. There are large gaps in data availability from low-income countries, especially from South East Asia and Africa regions.

Global Disease Burden of Respiratory Syncytial Virus in Preterm Children in 2019: A Systematic Review and Individual Participant Data Meta-Analysis Protocol.

Existing guidelines on respiratory syncytial virus (RSV) prophylaxis differ greatly by gestational age (GA) and other underlying risk factors, highlighting the data gaps in RSV disease burden among preterm infants. We will conduct a systematic review and individual participant data (IPD) meta-analysis of RSV global disease burden among preterm-born children. Three databases, Medline, Embase, and Global Health, will be searched for relevant studies on RSV disease burden for 2019 or before in preterm-born children published between 1 January 1995 and 31 December 2021. IPD will be sought by contacting the investigators identified from published literature and from existing collaboration networks. One-stage and 2-stage random-effects meta-analyses will be used to combine information from IPD and non-IPD studies to produce summary RSV burden estimates of incidence rate, hospital admission rate, and in-hospital case fatality ratio. The framework will be extended to examine subgroup(s) with the most substantial RSV disease burden.
