Project description:Pediatric severe sepsis remains a significant global health problem without new therapies despite many multicenter clinical trials. We compared children managed with severe sepsis in European and U.S. PICUs to identify geographic variation, which may improve the design of future international studies.We conducted a secondary analysis of the Sepsis PRevalence, OUtcomes, and Therapies study. Data about PICU characteristics, patient demographics, therapies, and outcomes were compared. Multivariable regression models were used to determine adjusted differences in morbidity and mortality.European and U.S. PICUs.Children with severe sepsis managed in European and U.S. PICUs enrolled in the Sepsis PRevalence, OUtcomes, and Therapies study.None.European PICUs had fewer beds (median, 11 vs 24; p < 0.001). European patients were younger (median, 1 vs 6 yr; p < 0.001), had higher severity of illness (median Pediatric Index of Mortality-3, 5.0 vs 3.8; p = 0.02), and were more often admitted from the ward (37% vs 24%). Invasive mechanical ventilation, central venous access, and vasoactive infusions were used more frequently in European patients (85% vs 68%, p = 0.002; 91% vs 82%, p = 0.05; and 71% vs 50%; p < 0.001, respectively). Raw morbidity and mortality outcomes were worse for European compared with U.S. patients, but after adjusting for patient characteristics, there were no significant differences in mortality, multiple organ dysfunction, disability at discharge, length of stay, or ventilator/vasoactive-free days.Children with severe sepsis admitted to European PICUs have higher severity of illness, are more likely to be admitted from hospital wards, and receive more intensive care therapies than in the United States. The lack of significant differences in morbidity and mortality after adjusting for patient characteristics suggests that the approach to care between regions, perhaps related to PICU bed availability, needs to be considered in the design of future international clinical trials in pediatric severe sepsis.

Project description:OBJECTIVE: To compare patient profiles and health care use for physician-referred and self-referred episodes of outpatient physical therapy (PT). DATA SOURCE: Five years (2003-2007) of private health insurance claims data, from a Midwest insurer, on beneficiaries aged 18-64. STUDY DESIGN: Retrospective analyses of health care use of physician-referred (N = 45,210) and self-referred (N = 17,497) ambulatory PT episodes of care was conducted, adjusting for age, gender, diagnosis, case mix, and year. DATA COLLECTION/EXTRACTION: Physical therapy episodes began with the physical therapist initial evaluation and ended on the last date of service before 60 days of no further visits. Episodes were classified as physician-referred if the patient had a physician claim from a reasonable referral source in the 30 days before the start of PT. PRINCIPAL FINDINGS: The self-referred group was slightly younger, but the two groups were very similar in regard to diagnosis and case mix. Self-referred episodes had fewer PT visits (86 percent of physician-referred) and lower allowable amounts ($0.87 for every $1.00), after covariate adjustment, but did not differ in related health care utilization after PT. CONCLUSIONS: Health care use during PT episodes was lower for those who self-referred, after adjusting for key variables, but did not differ after the PT episode.

Project description:OBJECTIVES:To compare the performance of three methods of identifying children with severe sepsis and septic shock from the Virtual Pediatric Systems database to prospective screening using consensus criteria. DESIGN:Observational cohort study. SETTING:Single-center PICU. PATIENTS:Children admitted to the PICU in the period between March 1, 2012, and March 31, 2014. INTERVENTIONS:None. MEASUREMENTS AND MAIN RESULTS:During the study period, all PICU patients were prospectively screened daily for sepsis, and those meeting consensus criteria for severe sepsis or septic shock on manual chart review were entered into the sepsis registry. Of 7,459 patients admitted to the PICU during the study period, 401 met consensus criteria for severe sepsis or septic shock (reference standard cohort). Within Virtual Pediatric Systems, patients identified using "Martin" (n = 970; ? = 0.43; positive predictive value = 34%; F1 = 0.48) and "Angus" International Classification of Diseases, 9th Edition, Clinical Modification codes (n = 1387; ? = 0.28; positive predictive value = 22%; F1 = 0.34) showed limited agreement with the reference standard cohort. By comparison, explicit International Classification of Diseases, 9th Edition, Clinical Modification codes for severe sepsis (995.92) and septic shock (785.52) identified a smaller, more accurate cohort of children (n = 515; ? = 0.61; positive predictive value = 57%; F1 = 0.64). PICU mortality was 8% in the reference standard cohort and the cohort identified by explicit codes; age, illness severity scores, and resource utilization did not differ between groups. Analysis of discrepancies between the reference standard and Virtual Pediatric Systems explicit codes revealed that prospective screening missed 66 patients with severe sepsis or septic shock. After including these patients in the reference standard cohort as an exploratory analysis, agreement between the cohort of patients identified by Virtual Pediatric Systems explicit codes and the reference standard cohort improved (? = 0.73; positive predictive value = 70%; F1 = 0.75). CONCLUSIONS:Children with severe sepsis and septic shock are best identified in the Virtual Pediatric Systems database using explicit diagnosis codes for severe sepsis and septic shock. The accuracy of these codes and level of clinical detail available in the Virtual Pediatric Systems database allow for sophisticated epidemiologic studies of pediatric severe sepsis and septic shock in this large, multicenter database.

Project description:To compare the prevalence, resource utilization, and mortality for pediatric severe sepsis identified using two established identification strategies.Observational cohort study from 2004 to 2012.Forty-four pediatric hospitals contributing data to the Pediatric Health Information Systems database.Children 18 years old or younger.We identified patients with severe sepsis or septic shock by using two International Classification of Diseases, 9th edition, Clinical Modification-based coding strategies: 1) combinations of International Classification of Diseases, 9th edition, Clinical Modification codes for infection plus organ dysfunction (combination code cohort); 2) International Classification of Diseases, 9th edition, Clinical Modification codes for severe sepsis and septic shock (sepsis code cohort). Outcomes included prevalence of severe sepsis, as well as hospital and ICU length of stay, and mortality. Outcomes were compared between the two cohorts examining aggregate differences over the study period and trends over time. The combination code cohort identified 176,124 hospitalizations (3.1% of all hospitalizations), whereas the sepsis code cohort identified 25,236 hospitalizations (0.45%), a seven-fold difference. Between 2004 and 2012, the prevalence of sepsis increased from 3.7% to 4.4% using the combination code cohort and from 0.4% to 0.7% using the sepsis code cohort (p < 0.001 for trend in each cohort). Length of stay (hospital and ICU) and costs decreased in both cohorts over the study period (p < 0.001). Overall, hospital mortality was higher in the sepsis code cohort than the combination code cohort (21.2% [95% CI, 20.7-21.8] vs 8.2% [95% CI, 8.0-8.3]). Over the 9-year study period, there was an absolute reduction in mortality of 10.9% (p < 0.001) in the sepsis code cohort and 3.8% (p < 0.001) in the combination code cohort.Prevalence of pediatric severe sepsis increased in the studied U.S. children's hospitals over the past 9 years, whereas resource utilization and mortality decreased. Epidemiologic estimates of pediatric severe sepsis varied up to seven-fold depending on the strategy used for case ascertainment.

Project description:Background: Early detection of pediatric severe sepsis is necessary in order to optimize effective treatment, and new methods are needed to facilitate this early detection. Objective: Can a machine-learning based prediction algorithm using electronic healthcare record (EHR) data predict severe sepsis onset in pediatric populations? Methods: EHR data were collected from a retrospective set of de-identified pediatric inpatient and emergency encounters for patients between 2-17 years of age, drawn from the University of California San Francisco (UCSF) Medical Center, with encounter dates between June 2011 and March 2016. Results: Pediatric patients (n = 9,486) were identified and 101 (1.06%) were labeled with severe sepsis following the pediatric severe sepsis definition of Goldstein et al. (1). In 4-fold cross-validation evaluations, the machine learning algorithm achieved an AUROC of 0.916 for discrimination between severe sepsis and control pediatric patients at the time of onset and AUROC of 0.718 at 4 h before onset. The prediction algorithm significantly outperformed the Pediatric Logistic Organ Dysfunction score (PELOD-2) (p < 0.05) and pediatric Systemic Inflammatory Response Syndrome (SIRS) (p < 0.05) in the prediction of severe sepsis 4 h before onset using cross-validation and pairwise t-tests. Conclusion: This machine learning algorithm has the potential to deliver high-performance severe sepsis detection and prediction through automated monitoring of EHR data for pediatric inpatients, which may enable earlier sepsis recognition and treatment initiation.

Project description:ObjectivesSevere sepsis is a significant cause of healthcare use and morbidity among pediatric patients, but little is known about readmission diagnoses. We sought to determine the most common readmission diagnoses after pediatric severe sepsis, the extent to which post-sepsis readmissions may be potentially preventable, and whether patterns of readmission diagnoses differ compared with readmissions after other common acute medical hospitalizations.DesignObservational cohort study.SettingNational Readmission Database (2013-2014), including all-payer hospitalizations from 22 states.PatientsFour-thousand five-hundred twenty-eight pediatric severe sepsis hospitalizations, matched by age, gender, comorbidities, and length of stay to 4,528 pediatric hospitalizations for other common acute medical conditions.InterventionsNone.Measurements and main resultsWe compared rates of 30-day all cause, diagnosis-specific, and potentially preventable hospital readmissions using McNemar's chi-square tests for paired data. Among 5,841 eligible pediatric severe sepsis hospitalizations with live discharge, 4,528 (77.5%) were matched 1:1 to 4,528 pediatric hospitalizations for other acute medical conditions. Of 4,528 matched sepsis hospitalizations, 851 (18.8% [95% CI, 16.0-18.2]) were rehospitalized within 30 days, compared with 775 (17.1% [95% CI, 17.1-20.0]) of matched hospitalizations for other causes (p = 0.02). The most common readmission diagnoses were chemotherapy, device complications, and sepsis, all of which were several-fold higher after sepsis versus after matched nonsepsis hospitalization. Only 11.5% of readmissions were for ambulatory care sensitive conditions compared with 23% of rehospitalizations after common acute medical conditions.ConclusionsMore than one in six children surviving severe sepsis were rehospitalized within 30 days, most commonly for maintenance chemotherapy, medical device complications, or recurrent sepsis. Only a small proportion of readmissions were for ambulatory care sensitive conditions.

Project description:ObjectiveTo examine differences in use of Veterans Health Administration (VA) and Medicare outpatient services by VA primary care patients.Data sources/study settingVA administrative and Medicare claims data from 2001 to 2004.Study designRetrospective cohort study of outpatient service use by 8,964 community-based and 6,556 hospital-based VA primary care patients.Principal findingsA significant proportion of VA patients used Medicare-reimbursed primary care (>30 percent) and specialty care (>60 percent), but not mental health care (3-4 percent). Community-based patients had 17 percent fewer VA primary care visits (p<.001), 9 percent more Medicare-reimbursed visits (p<.001), and 6 percent fewer total visits (p<.05) than hospital-based patients. Community-based patients had 22 percent fewer VA specialty care visits (p<.0001) and 21 percent more Medicare-reimbursed specialty care visits (p<.0001) than hospital-based patients, but no difference in total visits (p=.80).ConclusionsMedicare-eligible VA primary care patients followed over 4 consecutive years used significant primary care and specialty care outside of VA. Community-based patients offset decreased VA use with increased service use paid by Medicare, suggesting that increasing access to VA primary care via community clinics may fragment veteran care in unintended ways. Coordination of care between VA and non-VA providers and health care systems is essential to improve the quality and continuity of care.

Project description:Importance:Urgent care (UC) centers are a growing option to address children's acute care needs, which may cause unanticipated changes in health care use. Objectives:To identify factors associated with high UC reliance among children enrolled in Medicaid and examine the association between UC reliance and outpatient health care use. Design, Setting, and Participants:A retrospective cohort study used deidentified data on 4?133?238 children from the Marketscan Medicaid multistate claims database to calculate UC reliance and outpatient health care use. Children were younger than 19 years, with 11 months or more of continuous Medicaid enrollment and 1 or more UC, emergency department (ED), primary care provider (PCP; physician, advanced practice nurse, or physician assistant; well-child care [WCC] or non-WCC), or specialist outpatient visit during the 2017 calendar year. Statistical analysis was conducted from November 11 to 26, 2019. Exposures:Urgent care, ED, PCP (WCC and non-WCC), and specialist visits based on coded location of services. Main Outcomes and Measures:Urgent care reliance, calculated by the number of UC visits divided by the sum of total outpatient (UC, ED, PCP, and specialist) visits. High UC reliance was defined as UC visits totaling more than 33% of all outpatient visits. Results:Of 4?133?238 children in the study, 2?090?278 (50.6%) were male, with a median age of 9 years (interquartile range, 4-13 years). A total of 223?239 children (5.4%) had high UC reliance. Children 6 to 12 years of age were more likely to have high UC reliance compared with children 13 to 18 years of age (adjusted odds ratio, 1.07; 95% CI, 1.06-1.09). Compared with white children, black children (adjusted odds ratio, 0.81; 95% CI, 0.81-0.82) and Hispanic children (adjusted odds ratio, 0.61; 95% CI, 0.60-0.61) were less likely to have high UC reliance. Adjusted for age, sex, race/ethnicity, and presence of chronic or complex conditions, children with high UC reliance had significantly fewer PCP encounters (WCC: adjusted rate ratio, 0.60; 95% CI, 0.60-0.61; and non-WCC: adjusted rate ratio, 0.41; 95% CI, 0.41-0.41), specialist encounters (adjusted rate ratio, 0.31; 95% CI, 0.31-0.31), and ED encounters (adjusted rate ratio, 0.68; 95% CI, 0.67-0.68) than children with low UC reliance. Conclusions and Relevance:High UC reliance occurred more often in healthy, nonminority, school-aged children and was associated with lower health care use across other outpatient settings. There may be an opportunity in certain populations to ensure that UC reliance does not disrupt the medical home model.

Project description:BackgroundSepsis sequelae include critical illness polyneuropathy, myopathy, wasting, neurocognitive deficits, post-traumatic stress disorder, depression and chronic pain. Little is known howlong-term sequelae following hospital discharge are treated. The aim of our study is to determine the effect of a primary care-based, long-term program on health-related quality of life in sepsis survivors.Methods/designIn a two-armed randomized multicenter interventional study, patients after sepsis (n = 290) will be assessed at 6, 12 and 24 months. Patients are eligible if severe sepsis or septic shock (ICD-10), at least two criteria of systemic inflammatory response syndrome (SIRS), at least one organ dysfunction and sufficient cognitive capacity are present. The intervention comprises 1) discharge management, 2) training of general practitioners and patients in evidence-based care for sepsis sequelae and 3) telephone monitoring of patients. At six months, we expect an improved primary outcome (health-related quality of life/SF-36) and improved secondary outcomes such as costs, mortality, clinical-, psycho-social- and process-of-care measures in the intervention group compared to the control group.DiscussionThis study evaluates a primary care-based, long-term program for patients after severe sepsis. Study results may add evidence for improved sepsis care management. General practitioners may contribute efficiently to sepsis aftercare.Trial registrationU1111-1119-6345.

Project description:IntroductionRecombinant human activated protein C (APC) therapy has been shown to reduce short-term mortality in patients with severe sepsis. However, survivors of sepsis may have long-term complications affecting health-related quality of life (HRQoL) and resource utilization. The objective of this study was to evaluate prospectively the effect of APC on long-term HRQoL and resource utilization compared with a nonrandomized control group that received standard care.MethodsThis was an observational cohort study at nine Canadian intensive care units. Patients with severe sepsis who survived to 28 days were recruited. Patients who received APC formed the treatment group and those that did not formed the standard care group. Patients who did not receive APC because of central nervous system bleeding risk were excluded from the standard care group. HRQoL (determined using the 36-item Short Form) and resource use were recorded at 28 days, and 3, 5 and 7 months.ResultsOne hundred patients were enrolled (64 in the standard care group and 36 in the APC group), with 70 patients completing all follow-up visits. Over the 6 months of follow up, APC-treated patients exhibited statistically significantly better scores for the physical component score (P = 0.04) and trends toward improvements in physical functioning (P = 0.12), role physical (P = 0.10) and bodily pain (P = 0.14) as compared with standard care patients. Shorter hospital length of stay was observed for the APC group (36 days versus 48 days; P = 0.05).ConclusionThese findings challenge earlier assumptions suggesting equivalent HRQoL and resource use in APC-treated and standard care patients who survive severe sepsis.
