Family Presence at the PICU Bedside: A Single-Center Retrospective Cohort Study.

OBJECTIVES: To determine factors associated with bedside family presence in the PICU and to understand how individual factors interact as barriers to family presence. DESIGN: Mixed methods study. SETTING: Tertiary children's hospital PICU. SUBJECTS: Five hundred twenty-three children of less than 18 years enrolled in the Seattle Children's Hospital Outcomes Assessment Program from 2011 to 2017. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Quantitative: Family was documented every 2 hours. Exposures included patient and illness characteristics and family demographic and socioeconomic characteristics. We used multivariable logistic regression to identify factors associated with presence of less than 80% and stratified results by self-reported race. Longer PICU length of stay (LOS), public insurance, and complex chronic conditions (C-CD) were associated with family presence of less than 80%. Self-reported race modified these associations; no factors were associated with lower bedside presence for White families, in contrast with multiple associations for non-White families including public insurance, C-CD, and longer LOS. Qualitative: Thematic analysis of social work notes for the 48 patients with family presence of less than 80% matched on age, LOS, and diagnosis to 48 patients with greater than or equal to 95% family presence. Three themes emerged: the primary caregiver's prior experiences with the hospital, relationships outside of the hospital, and additional stressors during the hospitalization affected bedside presence. CONCLUSIONS: We identified sociodemographic and illness factors associated with family bedside presence in the PICU. Self-reported race modified these associations, representing racism within healthcare. Family presence at the bedside may help identify families facing greater disparities in healthcare access.

Epidemiology of Intensive Care Admissions for Children in the US From 2001 to 2019.

Importance: Estimates of the number of US children receiving intensive care unit (ICU) care and ICU admission patterns over time are lacking. Objective: To determine how ICU admission patterns, use of critical care services, and the characteristics and outcomes of critically ill children have changed from 2001 to 2019. Design, Setting, and Participants: This population-based retrospective cohort study used data from the Healthcare Cost and Utilization Project's state inpatient databases from a total of 21 US states in 2001, 2004, 2010, 2016, and 2019. Hospitalized children aged 0 to 17 years, excluding newborns (during birth hospitalization), were included. Patients admitted to rehabilitation institutions or psychiatric hospitals were also excluded. Data were analyzed from July 2021 to December 2022. Exposures: Care in a nonneonatal ICU. Main Outcomes and Measures: From extracted patient data, International Classification of Diseases, Ninth Revision, Clinical Modification, and Tenth Revision, Clinical Modification, codes were used to identify diagnoses, comorbid conditions, organ failures, and mechanical ventilation. Generalized linear Poisson regression and the Cuzick test were used to evaluate trends. US Census data were used to generate age- and sex-adjusted national estimates of ICU admissions and costs. Results: Of 2 157 991 pediatric admissions, 275 656 (12.8%) included ICU care. The mean (SD) age was 6.43 (6.10) years; 121 894 individuals were female (44.2%), and 153 731 were male (55.8%). From 2001 to 2019, the prevalence of ICU care among hospitalized children increased from 10.6% to 15.5%. The percentage of ICU admissions in children's hospitals rose from 51.2% to 85.1% (relative risk [RR], 1.66; 95% CI, 1.64-1.68). The percentage of children admitted to an ICU with an underlying comorbidity increased from 46.2% to 57.0% (RR, 1.23; 95% CI, 1.22-1.25), and the percentage with preadmission technology dependence increased from 16.4% to 23.5% (RR, 1.44; 95% CI, 1.40-1.48). The prevalence of multiple organ dysfunction syndrome increased from 6.8% to 21.0% (RR, 3.12; 95% CI, 2.98-3.26), while mortality decreased from 2.5% to 1.8% (RR, 0.72; 95% CI, 0.66-0.79). Hospital length of stay increased by 0.96 days (95% CI, 0.73-1.18) for ICU admissions from 2001 to 2019. After inflation adjustment, total costs for a pediatric admission involving ICU care nearly doubled between 2001 and 2019. Nationally, an estimated 239 000 children were admitted to a US ICU in 2019, corresponding to $11.6 billion in hospital costs. Conclusions and Relevance: In this study, the prevalence of children receiving ICU care in the US increased, as did length of stay, technology use, and associated costs. The US health care system must be equipped to care for these children in the future.

Association of Socioeconomic Status With Postdischarge Pediatric Resource Use and Quality of Life.

OBJECTIVES: Socioeconomic factors may impact healthcare resource use and health-related quality of life, but their association with postcritical illness outcomes is unknown. This study examines the associations between socioeconomic status, resource use, and health-related quality of life in a cohort of children recovering from acute respiratory failure. DESIGN: Secondary analysis of data from the Randomized Evaluation of Sedation Titration for Respiratory Failure clinical trial. SETTING: Thirty-one PICUs. PATIENTS: Children with acute respiratory failure enrolled whose parent/guardians consented for follow-up. MEASUREMENTS AND MAIN RESULTS: Resource use included in-home care, number of healthcare providers, prescribed medications, home medical equipment, emergency department visits, and hospital readmission. Socioeconomic status was estimated by matching residential address to census tract-based median income. Health-related quality of life was measured using age-based parent-report instruments. Resource use interviews with matched census tract data (n = 958) and health-related quality of life questionnaires (n = 750/958) were assessed. Compared with high-income children, low-income children received care from fewer types of healthcare providers (ß = -0.4; p = 0.004), used less newly prescribed medical equipment (odds ratio = 0.4; p < 0.001), and had more emergency department visits (43% vs 33%; p = 0.04). In the youngest cohort (< 2 yr old), low-income children had lower quality of life scores from physical ability (-8.6 points; p = 0.01) and bodily pain/discomfort (+8.2 points; p < 0.05). In addition, health-related quality of life was lower in those who had more healthcare providers and prescribed medications. In older children, health-related quality of life was lower if they had prescribed medications, emergency department visits, or hospital readmission. CONCLUSIONS: Children recovering from acute respiratory failure have ongoing healthcare resource use. Yet, lower income children use less in-home and outpatient services and use more hospital resources. Continued follow-up care, especially in lower income children, may help identify those in need of ongoing healthcare resources and those at-risk for decreased health-related quality of life.

Global, regional, and national sepsis incidence and mortality, 1990-2017: analysis for the Global Burden of Disease Study.

BACKGROUND: Sepsis is life-threatening organ dysfunction due to a dysregulated host response to infection. It is considered a major cause of health loss, but data for the global burden of sepsis are limited. As a syndrome caused by underlying infection, sepsis is not part of standard Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) estimates. Accurate estimates are important to inform and monitor health policy interventions, allocation of resources, and clinical treatment initiatives. We estimated the global, regional, and national incidence of sepsis and mortality from this disorder using data from GBD 2017. METHODS: We used multiple cause-of-death data from 109 million individual death records to calculate mortality related to sepsis among each of the 282 underlying causes of death in GBD 2017. The percentage of sepsis-related deaths by underlying GBD cause in each location worldwide was modelled using mixed-effects linear regression. Sepsis-related mortality for each age group, sex, location, GBD cause, and year (1990-2017) was estimated by applying modelled cause-specific fractions to GBD 2017 cause-of-death estimates. We used data for 8·7 million individual hospital records to calculate in-hospital sepsis-associated case-fatality, stratified by underlying GBD cause. In-hospital sepsis-associated case-fatality was modelled for each location using linear regression, and sepsis incidence was estimated by applying modelled case-fatality to sepsis-related mortality estimates. FINDINGS: In 2017, an estimated 48·9 million (95% uncertainty interval [UI] 38·9-62·9) incident cases of sepsis were recorded worldwide and 11·0 million (10·1-12·0) sepsis-related deaths were reported, representing 19·7% (18·2-21·4) of all global deaths. Age-standardised sepsis incidence fell by 37·0% (95% UI 11·8-54·5) and mortality decreased by 52·8% (47·7-57·5) from 1990 to 2017. Sepsis incidence and mortality varied substantially across regions, with the highest burden in sub-Saharan Africa, Oceania, south Asia, east Asia, and southeast Asia. INTERPRETATION: Despite declining age-standardised incidence and mortality, sepsis remains a major cause of health loss worldwide and has an especially high health-related burden in sub-Saharan Africa. FUNDING: The Bill & Melinda Gates Foundation, the National Institutes of Health, the University of Pittsburgh, the British Columbia Children's Hospital Foundation, the Wellcome Trust, and the Fleming Fund.

PICU-Based Rehabilitation and Outcomes Assessment: A Survey of Pediatric Critical Care Physicians.

OBJECTIVES: Characterize current practices for PICU-based rehabilitation, and physician perceptions and attitudes, barriers, resources, and outcome assessment in contemporary PICU settings. DESIGN: International, self-administered, quantitative, cross-sectional survey. SETTING: Online survey distributed from March 2017 to April 2017. PATIENTS OR SUBJECTS: Pediatric critical care physicians who subscribed to email distribution lists of the Pediatric Acute Lung Injury and Sepsis Investigators, the Pediatric Neurocritical Care Research Group, or the Prevalence of Acute Critical Neurological Disease in Children: A Global Epidemiological Assessment study group, and visitors to the World Federation of Pediatric Intensive and Critical Care Societies website. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of the 170 subjects who began the survey, 148 completed it. Of those who completed the optional respondent information, most reported working in an academic medical setting and were located in the United States. The main findings were 1) a large majority of PICU physicians reported working in institutions with no guidelines for PICU-based rehabilitation, but expressed interest in developing and implementing such guidelines; 2) despite this lack of guidelines, an overwhelming majority of respondents reported that their current practices would involve consultation of multiple rehabilitation services for each case example provided; 3) PICU physicians believed that additional research evidence is needed to determine efficacy and optimal implementation of PICU-based rehabilitation; 4) PICU physicians reported significant barriers to implementation of PICU-based rehabilitation across centers; and 5) low routine assessment of long-term functional outcomes of PICU patients, although some centers have developed multidisciplinary follow-up programs. CONCLUSIONS: Physicians lack PICU-based rehabilitation guidelines despite great interest and current practices involving a high degree of PICU-based rehabilitation consultation. Data are needed to identify best practices and necessary resources in the delivery of ICU-based multidisciplinary rehabilitation and long-term functional outcomes assessment to optimize recovery of children and families affected by critical illness.

An Intensive, Simulation-Based Communication Course for Pediatric Critical Care Medicine Fellows.

OBJECTIVE: Effective communication among providers, families, and patients is essential in critical care but is often inadequate in the PICU. To address the lack of communication education pediatric critical care medicine fellows receive, the Children's Hospital of Pittsburgh PICU developed a simulation-based communication course, Pediatric Critical Care Communication course. Pediatric critical care medicine trainees have limited prior training in communication and will have increased confidence in their communication skills after participating in the Pediatric Critical Care Communication course. DESIGN: Pediatric Critical Care Communication is a 3-day course taken once during fellowship featuring simulation with actors portraying family members. SETTING: Off-site conference space as part of a pediatric critical care medicine educational curriculum. SUBJECTS: Pediatric Critical Care Medicine Fellows. INTERVENTIONS: Didactic sessions and interactive simulation scenarios. MEASUREMENTS AND MAIN RESULTS: Prior to and after the course, fellows complete an anonymous survey asking about 1) prior instruction in communication, 2) preparedness for difficult conversations, 3) attitudes about end-of-life care, and 4) course satisfaction. We compared pre- and postcourse surveys using paired Student t test. Most of the 38 fellows who participated over 4 years had no prior communication training in conducting a care conference (70%), providing bad news (57%), or discussing end-of-life options (75%). Across all four iterations of the course, fellows after the course reported increased confidence across many topics of communication, including giving bad news, conducting a family conference, eliciting both a family's emotional reaction to their child's illness and their concerns at the end of a child's life, discussing a child's code status, and discussing religious issues. Specifically, fellows in 2014 reported significant increases in self-perceived preparedness to provide empathic communication to families regarding many aspects of discussing critical care, end-of-life care, and religious issues with patients' families (p < 0.05). The majority of fellows (90%) recommended that the course be required in pediatric critical care medicine fellowship. CONCLUSIONS: The Pediatric Critical Care Communication course increased fellow confidence in having difficult discussions common in the PICU. Fellows highly recommend it as part of PICU education. Further work should focus on the course's impact on family satisfaction with fellow communication.

International Survey of Critically Ill Children With Acute Neurologic Insults: The Prevalence of Acute Critical Neurological Disease in Children: A Global Epidemiological Assessment Study.

OBJECTIVE: The international scope of critical neurologic insults in children is unknown. Our objective was to assess the prevalence and outcomes of children admitted to PICUs with acute neurologic insults. DESIGN: Prospective study. SETTING: Multicenter (n = 107 PICUs) and multinational (23 countries, 79% in North America and Europe). PATIENTS: Children 7 days to 17 years old admitted to the ICU with new traumatic brain injury, stroke, cardiac arrest, CNS infection or inflammation, status epilepticus, spinal cord injury, hydrocephalus, or brain mass. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We evaluated the prevalence and outcomes of children with predetermined acute neurologic insults. Child and center characteristics were recorded. Unfavorable outcome was defined as change in pre-post insult Pediatric Cerebral Performance Category score greater than or equal to 2 or death at hospital discharge or 3 months, whichever came first. Screening data yielded overall prevalence of 16.2%. Of 924 children with acute neurologic insults, cardiac arrest (23%) and traumatic brain injury (19%) were the most common. All-cause mortality at hospital discharge was 12%. Cardiac arrest subjects had highest mortality (24%), and traumatic brain injury subjects had the most unfavorable outcomes (49%). The most common neurologic insult was infection/inflammation in South America, Asia, and the single African site but cardiac arrest in the remaining regions. CONCLUSIONS: Neurologic insults are a significant pediatric international health issue. They are frequent and contribute substantial morbidity and mortality. These data suggest a need for an increased focus on acute critical neurologic diseases in infants and children including additional research, enhanced availability of clinical resources, and the development of new therapies.

Trends in the epidemiology of pediatric severe sepsis*.

OBJECTIVES: In the past decade, guidelines have been developed for the early detection and management of severe sepsis in children and neonates. However, severe sepsis continues to be a significant U.S. healthcare problem, accounting for over 720,000 annual hospitalizations. Large-scale epidemiologic studies of severe sepsis continue to be limited, particularly in children. We present data from 1995, 2000, and 2005 in seven U.S. states, examining how case mix, outcome, and resource use for pediatric severe sepsis have changed over time. DESIGN: We constructed a database including all acute-care hospitalizations for children in the seven states. For each case, we extracted data on demographic characteristics; the principal diagnosis, up to six secondary diagnoses, and six procedures as classified by the International Classification of Diseases, 9th Revision, Clinical Modification codes; and in-hospital fatality. We identified patients with severe sepsis using International Classification of Diseases, 9th Revision, Clinical Modification codes for both infection and acute organ failure. SETTING: Retrospective observational cohort dataset from seven U.S. states from 1995, 2000, and 2005. SUBJECTS: Children in the U.S. 0-19 years old. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: In 2005, 17,542 children were hospitalized with severe sepsis in the seven states; there was an 81% increase in pediatric severe sepsis cases since 1995 and a 45% increase since 2000. This corresponded to an increase in prevalence from 0.56 to 0.89 cases per 1,000 pediatric population. Between 1995 and 2005, the prevalence of severe sepsis in newborns more than doubled, from 4.5 to 9.7 cases per 1,000 births. The most common infecting organisms in all 3 years were Staphylococcus species. From 1995 to 2005, the case-fatality rate decreased from 10.3% to 8.9%. Case fatality associated with Staphylococcus aureus increased, whereas fatality associated with Streptococcus pneumoniae decreased by 75%. Nationally, there were 75,255 pediatric hospitalizations in 2005 involving severe sepsis, with an associated cost of $4.8 billion. CONCLUSIONS: Between 1995 and 2005, the prevalence of severe sepsis in U.S. children steadily rose, due to a significant increase in the prevalence of severe sepsis in newborns.

Hospitalizations of children with neurologic disorders in the United States.

OBJECTIVES: Although neurologic disorders are among the most serious acute pediatric illnesses, epidemiologic data are scarce. We sought to determine the scope and outcomes of children with these disorders in the United States. DESIGN: Retrospective cohort study. SETTING: All nonfederal hospitals in 11 states encompassing 38% of the U.S. pediatric population. PATIENTS: Children 29 days to 19 years old hospitalized in 2005. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Using International Classification of Diseases, 9th Revision, Clinical Modification, codes, we identified admissions with neurologic diagnoses, analyzed patient and hospitalization characteristics, and generated age- and sex-adjusted national estimates. Of 960,020 admissions in the 11 states, 10.7% (103,140) included a neurologic diagnosis, which yields a national estimate of 273,900 admissions of children with neurologic diagnoses. The most common were seizures (53.9%) and traumatic brain injury (17.3%). Children with neurologic diagnoses had nearly three times greater ICU use than other hospitalized children (30.6% vs 10.6%, p < 0.001). Neurologic diagnoses were associated with nearly half of deaths (46.2%, n = 1,790). Among ICU patients, children with neurologic diagnoses had more than three times the mortality of other patients (4.8% vs1.5%, p < 0.001). Children with neurologic diagnoses had a significantly longer median hospital length of stay than other children (3 d [1, 5] vs 2 d [2, 4], p < 0.001) and greater median hospital costs ($4,630 [$2,380, $9,730] vs $2,840 [$1,520, $5,550], p < 0.001). CONCLUSIONS: Children with neurologic diagnoses account for a disproportionate amount of ICU stays and deaths compared with children hospitalized for other reasons.

Trends in admissions for pediatric status asthmaticus in New Jersey over a 15-year period.

OBJECTIVE: Status asthmaticus accounts for a large portion of the morbidity and mortality associated with asthma, but we know little about its epidemiology. We describe here the hospitalization characteristics of children with status asthmaticus, how they changed over time, and how they differed between hospitals with and without PICUs. PATIENTS AND METHODS: We used administrative data from New Jersey that included all hospitalizations in the state from 1992, 1995, and 1999-2006. We identified children with status asthmaticus by using International Classification of Diseases, Ninth Revision, diagnosis codes that indicate status asthmaticus and the use of mechanical ventilation by using procedure codes. We designated hospitals with a PICU as "PICU hospitals" and those without as "adult hospitals." RESULTS: We identified 28 309 admissions of children with status asthmaticus (22.8% of all asthma hospitalizations). From 1992 to 2006, the rate of hospital admissions decreased by half (from 1.98 in 1000 to 0.93 in 1000 children), and there was a 70% decrease in the number of children admitted to adult hospitals. The rate of ICU care in PICU hospitals more than tripled. However, the rate of mechanical ventilation remained low, and the number of deaths was small and unchanged (n=14 total). Hospital costs climbed from $6.6 million to $9.5 million. CONCLUSIONS: Although fewer children are being admitted with status asthmaticus, the proportion of patients managed in PICUs is climbing. There has been no substantial change in rates of mechanical ventilation or death. Additional research is needed to better understand how patients and physicians decide on the appropriate site for hospital care and how that choice affects outcome.

Clinical and economic effects of iNO in premature newborns with respiratory failure at 1 year.

BACKGROUND: The long-term consequences of inhaled nitric oxide (iNO) use in premature newborns with respiratory failure are unknown. We therefore studied the clinical and economic outcomes to 1 year of corrected age after a randomized controlled trial of prophylactic iNO. METHODS: Premature newborns (gestational age

Scope and epidemiology of pediatric sepsis.

OBJECTIVE: To summarize the scope and epidemiology of pediatric sepsis. DESIGN: Review of published literature. RESULTS: Sepsis is a leading cause of death in infants and children, with >42,000 cases of severe sepsis annually in the United States and millions worldwide. Half of the children with severe sepsis in the United States are infants, and half of infants are low- or very low-birth-weight babies. Underlying disease occurs in 49% of U.S. children with severe sepsis. National hospital costs associated with severe sepsis in the United States were $2.3 billion in 1999. Relatively simple strategies to identify and treat children with sepsis in the developing world have shown remarkable success. These strategies have included empirical antibiotics in babies at high risk of sepsis and aggressive fluid resuscitation in Dengue hemorrhagic fever. CONCLUSIONS: Sepsis is a major health problem among children in both developing and industrialized countries. However, sepsis is both preventable and treatable. Improved prevention and treatment of sepsis could have a substantial effect on survival and quality of life of all children, both those who are otherwise healthy and those who are chronically ill. The variations in the epidemiology of pediatric sepsis underscore the need for a multidisciplinary approach and consistently applied definitions.

Use of intensive care at the end of life in the United States: an epidemiologic study.

OBJECTIVE: Despite concern over the appropriateness and quality of care provided in an intensive care unit (ICU) at the end of life, the number of Americans who receive ICU care at the end of life is unknown. We sought to describe the use of ICU care at the end of life in the United States using hospital discharge data from 1999 for six states and the National Death Index. DESIGN: Retrospective analysis of administrative data to calculate age-specific rates of hospitalization with and without ICU use at the end of life, to generate national estimates of end-of-life hospital and ICU use, and to characterize age-specific case mix of ICU decedents. SETTING: All nonfederal hospitals in the states of Florida, Massachusetts, New Jersey, New York, Virginia, and Washington. PATIENTS: All inpatients in nonfederal hospitals in the six states in 1999. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: We found that there were 552,157 deaths in the six states in 1999, of which 38.3% occurred in hospital and 22.4% occurred after ICU admission. Using these data to project nationwide estimates, 540,000 people die after ICU admission each year. The age-specific rate of ICU use at the end of life was highest for infants (43%), ranged from 18% to 26% among older children and adults, and fell to 14% for those >85 yrs. Average length of stay and costs were 12.9 days and $24,541 for terminal ICU hospitalizations and 8.9 days and $8,548 for non-ICU terminal hospitalizations. CONCLUSIONS: One in five Americans die using ICU services. The doubling of persons over the age of 65 yrs by 2030 will require a system-wide expansion in ICU care for dying patients unless the healthcare system pursues rationing, more effective advanced care planning, and augmented capacity to care for dying patients in other settings.

Cost-effectiveness of inhaled nitric oxide in the treatment of neonatal respiratory failure in the United States.

OBJECTIVE: Two recent randomized controlled trials (RCTs) reported that inhaled nitric oxide (iNO) decreased the incidence of extracorporeal membrane oxygenation (ECMO) or death in term and near-term newborns with hypoxic respiratory failure. Our objective was to estimate the cost-effectiveness ratio of iNO in this population. METHODS: We studied 1000 simulation cohorts (n = 483 for each cohort) of term/near-term newborns with hypoxemic respiratory failure. We conducted our study following US Public Health Service Panel on Cost-Effectiveness in Health and Medicine guidelines, adopting the US societal perspective. We constructed a decision tree reflecting iNO use, subsequent ECMO use, death, and long-term neurologic and respiratory morbidity in survivors, as determined from the combined outcomes of the 2 RCTs (n = 483). We estimated costs on the basis of length-of-stay data for the initial episode of care from 1 of the RCTs, unit costs from administrative data sets, and current pricing for iNO. We ran a Monte Carlo simulation to generate estimates of differences in costs and effects at 1 year, along with the stochastic uncertainty around these estimates. We expressed effects as quality-adjusted survival, assuming quality of life = 1 with no comorbidity, 0.7 with 1 comorbidity, and 0.49 (0.7 x 0.7) with 2 comorbidities. We constructed a base case, in which iNO was initiated at tertiary care ECMO centers (mimicking the RCTs) and a Public Health Service Panel on Cost-effectiveness in Health and Medicine reference case, in which iNO was initiated at the local hospital before transfer (mimicking real-world practice). We exposed our assumptions to a sensitivity analysis. RESULTS: Direct application of the trial results (base case) suggested that iNO was both more effective and cheaper (cost savings of 1880 dollars per case despite acquisition costs of 5150 dollars, predominantly as a result of decreased need for ECMO), with 84.6% probability that the cost-effectiveness ratio was better than 100,000 dollars per quality-adjusted life-year. Under the reference case, iNO was also more effective (though slightly less so) and was even cheaper (cost savings of 4400 dollars per case), with 71.6% probability that iNO was cheaper and more effective and 91.6% probability that the cost effectiveness ratio was better than 100,000 dollars per quality-adjusted life-year. Sensitivity analyses showed these estimates to be sensitive to patient selection and the price of iNO but insensitive to assumptions regarding quality of life. CONCLUSIONS: From a US societal perspective, iNO has a favorable cost-effectiveness profile when initiated either at ECMO centers or at local hospitals in term/near-term neonates with hypoxemic respiratory failure.

Pneumonia: still the old man's friend?

BACKGROUND: Hospital mortality of patients admitted with community-acquired pneumonia (CAP) has been well described. However, the long-term survival of those discharged alive is less clear. We sought to determine long-term survival of patients hospitalized with CAP and compare the outcome with controls hospitalized for reasons other than CAP. METHODS: We performed a matched case-control analysis using the Medicare hospital discharge database from the first quarter of 1997. We compared all Medicare recipients 65 years or older hospitalized with CAP and controls matched for age, sex, and race hospitalized for reasons other than CAP. We measured 1-year mortality determined from the Medicare Beneficiary Entitlement file and the Social Security Administration. RESULTS: We identified 158 960 CAP patients and 794 333 hospitalized controls. Hospital mortality rates for the CAP cohort and hospitalized controls were 11.0% and 5.5%, respectively (P<.001). One-year mortality rates for the CAP cohort and hospitalized controls were 40.9% and 29.1%, respectively (P<.001). One-year mortality rates in hospital survivors of the CAP and control cohorts were 33.6% and 24.9%, respectively (P<.001). The difference in mortality between the CAP and control cohorts was not explained by underlying disease. Standardized against the general population, the risk of death for both cohorts decreased monthly but was still elevated 1 year after hospital discharge. The standardized mortality ratio was 2.69 (95% confidence interval, 2.47-2.93) for CAP patients and 1.93 (95% confidence interval, 1.79-2.08) for hospital controls. CONCLUSIONS: Almost half of all elderly patients admitted for CAP die in the subsequent year, with most deaths occurring after hospital discharge. The mortality is considerably higher than that of either the general population or a control population hospitalized for reasons other than CAP.

The epidemiology of severe sepsis in children in the United States.

Despite extensive research into the etiology and treatment of severe sepsis, little is known about its epidemiology in children. We sought to determine the age- and sex-adjusted incidence, outcome, and associated hospital costs of severe sepsis in United States children using 1995 hospital discharge and population data from seven states (24% of the United States population). Of 1,586,253 hospitalizations in children who were 19 years old or less, 9,675 met International Classification of Diseases, 9th revision, clinical modification-based severe sepsis criteria or 42,364 cases of pediatric severe sepsis per year nationally (0.56 cases per 1,000 population per year). The incidence was the highest in infants (5.16 per 1,000), fell dramatically in older children (0.20 per 1,000 in 10 to 14 year olds), and was 15% higher in boys than in girls (0.60 versus 0.52 per 1,000, p < 0.001). Hospital mortality was 10.3%, or 4,383 deaths nationally (6.2 per 100,000 population). Half of the cases had underlying disease (49.0%), and over one-fifth (22.9%) were low-birth-weight newborns. Respiratory infections (37%) and primary bacteremia (25%) were the most common infections. The mean length of stay and cost were 31 days and $40,600, respectively. Estimated annual total costs were 1.97 billion US dollars nationally. Severe sepsis is a significant health problem in children and is associated with the use of extensive healthcare resources. Infants are at highest risk, especially those with a low birth weight.
