OBJECTIVE. Brief hospitalizations for children may constitute an opportunity to provide care in an alternative setting such as an observation unit. The goal of this study was to characterize recent national trends in brief inpatient stays for children in the United States. METHODS. Using the Nationwide Inpatient Sample from 1993–2003, we analyzed hospital discharges among children <18 years of age, excluding births, deaths, and transfers. Hospitalizations with lengths of stay of 0 and 1 night were designated as “high turnover.” Serial cross-sectional analyses were conducted to compare the proportion of high-turnover stays across and within years according to patient and hospital-level characteristics. Diagnosis-related groups and hospital charges associated with these observation-length stays were examined. RESULTS. In 2003, there were an estimated 441 363 high-turnover hospitalizations compared with 388 701 in 1993. The proportion of high-turnover stays increased from 24.9% in 1993 to 29.9% in 1999 and has remained ≥30.0% since that time. Diagnosis-related groups for high-turnover stays reflect common pediatric medical and surgical conditions requiring hospitalization, including respiratory illness, gastrointestinal/metabolic disorders, seizure/headache, and appendectomy. Significant increases in the proportion of high-turnover stays during the study period were noted across patient and hospital-level characteristics, including age group, payer, hospital location, teaching status, bed size, and admission source. High-turnover stays contributed

494 million (12%) in 1993. CONCLUSIONS. Consistently since 1999, nearly one third of children hospitalized in the United States experience a high-turnover stay. These high-turnover cases constitute hospitalizations, that may be eligible for care in an alternative setting. Observation units provide 1 model for an efficient and cost-effective alternative to inpatient care, in which resources and provider interactions with patients and each other are geared toward shorter stays with more timely discharge processes.

BACKGROUND As more efficient and value-based care models are sought for the US healthcare system, geographically distinct observation units (OUs) may become an integral part of hospital-based care for children. PURPOSE To systematically review the literature and evaluate the structure and function of pediatric OUs in the United States. DATA SOURCES Searches were conducted in Medline, Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Health Care Advisory Board (HCAB), Lexis-Nexis, National Guideline Clearinghouse, and Cochrane Reviews, through February 2009, with review of select bibliographies. STUDY SELECTION English language peer-reviewed publications on pediatric OU care in the United States. DATA EXTRACTION Two authors independently determined study eligibility. Studies were graded using a 5-level quality assessment tool. Data were extracted using a standardized form. DATA SYNTHESIS A total of 21 studies met inclusion criteria: 2 randomized trials, 2 prospective observational, 12 retrospective cohort, 2 before and after, and 3 descriptive studies. Studies present data on more than 22,000 children cared for in OUs, most at large academic centers. This systematic review provides a descriptive overview of the structure and function of pediatric OUs in the United States. Despite seemingly straightforward outcomes for OU care, significant heterogeneity in the reporting of length of stay, admission rates, return visit rates, and costs precluded our ability to conduct meta-analyses. We propose standard outcome measures and future directions for pediatric OU research. CONCLUSIONS Future research using consistent outcome measures will be critical to determining whether OUs can improve the quality and cost of providing care to children requiring observation-length stays.

The ongoing spread of H5N1 avian influenza in Southeast Asia has raised concern about a worldwide influenza pandemic and has made clear the need to plan in advance for such an event. The federal government has stressed the importance of planning and, in particular, has asked hospitals and public health agencies to develop plans to care for patients outside of traditional healthcare settings. These alternative or acute care centers (ACCs) would be opened when hospitals, emergency departments (EDs), and clinics are overwhelmed by an influenza pandemic. The University of Michigan Hospital System (UMHS), a large tertiary care center in southeast Michigan, has been developing a model for offsite care of patients during an influenza pandemic. This article summarizes our planning efforts and the lessons learned from 2 functional exercises over the past 3 years.

We are currently in the midst of the 2009 H1N1 pandemic, and a second wave of flu in the fall and winter could lead to more hospitalizations for pneumonia. Recent pathologic and historic data from the 1918 influenza pandemic confirms that many, if not most, of the deaths in that pandemic were a result of secondary bacterial pneumonias. This means that a second wave of 2009 H1N1 pandemic influenza could result in a widespread shortage of antibiotics, making these medications a scarce resource. Recently, our University of Michigan Health System (UMHS) Scarce Resource Allocation Committee (SRAC) added antibiotics to a list of resources (including ventilators, antivirals, vaccines) that might become scarce during an influenza pandemic. In this article, we summarize the data on bacterial pneumonias during the 1918 influenza pandemic, discuss the possible impact of a pandemic on the University of Michigan Health System, and summarize our committees guiding principles for allocating antibiotics during a pandemic.

OBJECTIVE To determine whether using emergency department (ED) virtual observation for select pediatric conditions decreases admission rates for these conditions, and to examine effects on length of stay. METHODS The option of ED virtual observation care for 9 common pediatric conditions was introduced in 2009; associated order sets were developed. Retrospective secondary analyses of administrative data from our tertiary care pediatric ED and childrens hospital were performed for the year before (year 0) and after (year 1) this disposition option was introduced. The proportion of visits admitted to the inpatient unit and length of stay (LOS) were determined for all visits considered eligible for ED virtual observation care on the basis of diagnosis codes for both study years. RESULTS There were 1614 observation-eligible visits in year 0 and 1510 in year 1. In year 1, 18% (n = 266) of observation-eligible visits received ED virtual observation care. Admission rates for observation-eligible visits were similar after this model of care was introduced (25% year 0, 29% year 1, P = .02). Median LOS for ED virtual observation visits was 8.8 hours (interquartile range 6.5-12.4). ED LOS was shorter for ED discharges (5.6 hours year 0, 5.1 hours year 1, P < .001) and unchanged for admissions (6.0 hours year 0, 5.8 hours, year 1, P = .41) after introducing ED virtual observation. CONCLUSIONS Admission rates for observation-eligible visits were not lower in the year after ED virtual observation care was introduced. LOS decreased for ED discharges and was unchanged for admissions. Reevaluation of the effects of pediatric ED virtual observation on admission rates and LOS after longer periods of use is indicated.

Study objective: We undertake this study to understand patterns of pediatric asthma‐related acute care use to inform interventions aimed at reducing potentially avoidable hospitalizations. Methods: Hospital claims data from 3 Camden city facilities for 2010 to 2014 were used to perform cluster analysis classifying patients aged 0 to 17 years according to their asthma‐related hospital use. Clusters were based on 2 variables: asthma‐related ED visits and hospitalizations. Demographics and a number of sociobehavioral and use characteristics were compared across clusters. Results: Children who met the criteria (3,170) were included in the analysis. An examination of a scree plot showing the decline in within‐cluster heterogeneity as the number of clusters increased confirmed that clusters of pediatric asthma patients according to hospital use exist in the data. Five clusters of patients with distinct asthma‐related acute care use patterns were observed. Cluster 1 (62% of patients) showed the lowest rates of acute care use. These patients were least likely to have a mental health–related diagnosis, were less likely to have visited multiple facilities, and had no hospitalizations for asthma. Cluster 2 (19% of patients) had a low number of asthma ED visits and onetime hospitalization. Cluster 3 (11% of patients) had a high number of ED visits and low hospitalization rates, and the highest rates of multiple facility use. Cluster 4 (7% of patients) had moderate ED use for both asthma and other illnesses, and high rates of asthma hospitalizations; nearly one quarter received care at all facilities, and 1 in 10 had a mental health diagnosis. Cluster 5 (1% of patients) had extreme rates of acute care use. Conclusion: Differences observed between groups across multiple sociobehavioral factors suggest these clusters may represent children who differ along multiple dimensions, in addition to patterns of service use, with implications for tailored interventions.

Fever is the most common complaint for a child to visit hospital. Under the aegis of INDO-US Emergency and Trauma Collaborative, Pediatric Emergency Medicine chapter of Academic College of Emergency Experts in India developed evidence-based consensus for evaluation and management of febrile child in emergency department. An extensive literature search and further online communication of the group led to the development of a detailed approach for the evaluation and management of individual conditions associated with fever. To develop an approach to individual conditions presenting with fever, that is, best suited to the epidemiology prevalent in India. The algorithmic approach given by the group describes in details the evaluation and management of specialized and individual conditions like fever and immunocompromised state, fever with localizing signs that include fever with seizures, cough, ear discharge, loose stools, rash and dysuria; fever without localization with epidemiological evidence supporting diagnosis such as malaria, enteric fever and dengue; and fever without any localization and no epidemiological evidence supporting the diagnosis.

Despite 90% of primary care providers at altitude reporting experience with home oxygen therapy for hypoxemic, otherwise well infants, its use at sea level is not well described. Our objective was to understand experience with home oxygen at sea level and determine potential barriers and benefits of its use. We surveyed all pediatricians and family medicine providers within a 30-mile radius of our pediatric hospital from May 2016 to December 2016. Forty-three percent of providers responded. Few (8%) had any experience with home oxygen therapy for bronchiolitis. When all responders were asked about potential benefits and barriers, they reported less disruption of family routines and reduced cost as the largest potential benefits, and lack of parental comfort the largest barrier. Despite their concerns, 53% of providers felt that home oxygen use would not substantially affect their practice. Our results identify a need for education before using this alternative to admission in our center.
