Epidemiological trends in invasive mechanical ventilation in the United States: A population-based study.

ABSTRACT: Epidemiological trends for invasive mechanical ventilation (IMV) have not been clearly defined. We sought to define trends for IMV in the United States and assess for disease-specific variation for 3 common causes of respiratory failure: pneumonia, heart failure (HF), and chronic obstructive pulmonary disease (COPD).We calculated national estimates for utilization of nonsurgical IMV cases from the Nationwide Inpatient Sample from 1993 to 2009 and compared trends for COPD, HF, and pneumonia.We identified 8309344 cases of IMV from 1993 to 2009. Utilization of IMV for nonsurgical indications increased from 178.9 per 100000 in 1993 to 310.9 per 100000 US adults in 2009. Pneumonia cases requiring IMV showed the largest increase (103.6%), whereas COPD cases remained relatively stable (2.5% increase) and HF cases decreased by 55.4%. Similar demographic and clinical changes were observed for pneumonia, COPD, and HF, with cases of IMV becoming younger, more ethnically diverse, and more frequently insured by Medicaid. Outcome trends for patients differed based on diagnosis. Adjusted hospital mortality decreased over time for cases of pneumonia (odds ratio [OR] per 5 years, 0.89; 95% confidence interval [CI], 0.88-0.90) and COPD (OR per 5 years, 0.97; 95% CI, 0.97-0.98) but increased for HF (OR per 5 years, 1.10; 95% CI, 1.09-1.12).Utilization of IMV in the US increased from 1993 to 2009 with a decrease in overall mortality. However, trends in utilization and outcomes of IMV differed markedly based on diagnosis. Unlike favorable outcome trends in pneumonia and COPD, hospital mortality for HF has not improved. Further studies to investigate the outcome gap between HF and other causes of respiratory failure are needed.

Project description:BackgroundCoronavirus disease 2019 (COVID-19) has exposed critical care supply shortages worldwide. This study aimed to investigate the association between regional critical care capacity and the incidence of invasive mechanical ventilation following novel COVID-19 during the pandemic in Japan, a country with a limited intensive care unit (ICU) bed capacity of a median of 5.1 ICU beds per 100,000 individuals.MethodsThis population-based cohort study used data from the CRoss Icu Searchable Information System database and publicly available databases provided by the Japanese government and Japanese Society of Intensive Care Medicine. We identified patients recently diagnosed with COVID-19, those who received invasive mechanical ventilation, and those who received extracorporeal membrane oxygenation (ECMO) between February 2020 and March 2023. We analyzed the association between regional critical care capacity (ICU beds, high-dependency care unit (HDU) beds, resource-rich ICU beds, and intensivists) and the incidence of invasive mechanical ventilation, ECMO, and risk-adjusted mortality across 47 Japanese prefectures.ResultsAmong the approximately 127 million individuals residing in Japan, 33,189,809 were recently diagnosed with COVID-19, with 12,203 and 1,426 COVID-19 patients on invasive mechanical ventilation and ECMO, respectively, during the study period. Prefecture-level linear regression analysis revealed that the addition of ICU beds, resource-rich ICU beds, and intensivists per 100,000 individuals increased the incidence of IMV by 5.37 (95% confidence interval, 1.99-8.76), 7.27 (1.61-12.9), and 13.12 (3.48-22.76), respectively. However, the number of HDU beds per 100,000 individuals was not statistically significantly associated with the incidence of invasive mechanical ventilation. None of the four indicators of regional critical care capacity was statistically significantly associated with the incidence of ECMO and risk-adjusted mortality.ConclusionsThe results of prefecture-level analyses demonstrate that increased numbers of ICU beds, resource-rich ICU beds, and intensivists are associated with the incidence of invasive mechanical ventilation among patients recently diagnosed with COVID-19 during the pandemic. These findings have important implications for healthcare policymakers, aiding in efficiently allocating critical care resources during crises, particularly in regions with limited ICU bed capacities.

Project description:ObjectiveIn view of mobile phone exposure being classified as a possible human carcinogen by the International Agency for Research on Cancer (IARC), we determined the compatibility of two recent reports of glioma risk (forming the basis of the IARC's classification) with observed incidence trends in the United States.DesignComparison of observed rates with projected rates of glioma incidence for 1997-2008. We estimated projected rates by combining relative risks reported in the 2010 Interphone study and a 2011 Swedish study by Hardell and colleagues with rates adjusted for age, registry, and sex; data for mobile phone use; and various latency periods.SettingUS population based data for glioma incidence in 1992-2008, from 12 registries in the Surveillance, Epidemiology, and End Results (SEER) programme (Atlanta, Detroit, Los Angeles, San Francisco, San Jose-Monterey, Seattle, rural Georgia, Connecticut, Hawaii, Iowa, New Mexico, and Utah).ParticipantsData for 24,813 non-Hispanic white people diagnosed with glioma at age 18 years or older.ResultsAge specific incidence rates of glioma remained generally constant in 1992-2008 (-0.02% change per year, 95% confidence interval -0.28% to 0.25%), a period coinciding with a substantial increase in mobile phone use from close to 0% to almost 100% of the US population. If phone use was associated with glioma risk, we expected glioma incidence rates to be higher than those observed, even with a latency period of 10 years and low relative risks (1.5). Based on relative risks of glioma by tumour latency and cumulative hours of phone use in the Swedish study, predicted rates should have been at least 40% higher than observed rates in 2008. However, predicted glioma rates based on the small proportion of highly exposed people in the Interphone study could be consistent with the observed data. Results remained valid if we used either non-regular users or low users of mobile phones as the baseline category, and if we constrained relative risks to be more than 1.ConclusionsRaised risks of glioma with mobile phone use, as reported by one (Swedish) study forming the basis of the IARC's re-evaluation of mobile phone exposure, are not consistent with observed incidence trends in US population data, although the US data could be consistent with the modest excess risks in the Interphone study.

Project description:BackgroundEpidemiologic assessment of surgical admissions into intensive care units (ICUs) provides a framework to evaluate health care system efficiency and project future health care needs.MethodsWe performed a 9-year (2008-2016), retrospective, cohort analysis of all adult admissions to 88 surgical ICUs using the prospectively and manually abstracted Cerner Acute Physiology and Chronic Health Evaluation Outcomes database. We stratified patients into 13 surgical cohorts and modeled temporal trends in admission, mortality, surgical ICU length of stay (LOS), and change in functional status (FS) using generalized mixed-effects and Quasi-Poisson models to obtain risk-adjusted outcomes.ResultsWe evaluated 78,053 ICU admissions and observed a significant decrease in admissions after transplant and thoracic surgery, with a concomitant increase in admissions after otolaryngological and facial reconstructive procedures (all p < 0.05). While overall risk-adjusted mortality remained stable over the study period; mortality significantly declined in orthopedic, cardiac, urologic, and neurosurgical patients (all p < 0.05). Cardiac, urologic, gastrointestinal, neurosurgical, and orthopedic admissions showed significant reductions in LOS (all p < 0.05). The overall rate of FS deterioration increased per year, suggesting ICU-related disability increased over the study period.ConclusionTemporal analysis demonstrates a significant change in the type of surgical patients admitted to the ICU over the last decade, with decreasing mortality and LOS in selected cohorts, but an increasing rate of FS deterioration. Improvement in ICU outcomes may highlight the success of health care advancements within certain surgical cohorts, while simultaneously identifying cohorts that may benefit from future intervention. Our findings have significant implications in health care systems planning, including resource and personnel allocation, education, and surgical training.Level of evidenceEconomic/decision, level IV.Epidemiologic, level IV.

Project description:Rationale: In 2016, the American Thoracic Society released clinical practice guidelines for pediatric chronic home invasive ventilation pertaining to discharge practices and subsequent management for patients with invasive ventilation using a tracheostomy. It is not known to what extent current U.S. practices adhere to these recommendations.Objectives: Hospital discharge practices and home health services are not standardized for children with invasive home mechanical ventilation (HMV). We assessed discharge practices for U.S. children with HMV.Methods: A survey of key-informant U.S. clinical providers of children with HMV, identified with purposeful and snowball sampling, was conducted. Topics included medical stability, family caregiver training, and discharge guidelines. Close-ended responses were analyzed using descriptive statistics. Responses to open-ended questions were analyzed using open coding with iterative modification for major theme agreement.Results: Eighty-eight responses were received from 157 invitations. Eligible survey responses from 59 providers, representing 44 U.S. states, included 49.2% physicians, 37.3% nurses, 10.2% respiratory therapists, and 3.4% case managers. A minority, 22 (39%) reported that their institution had a standard definition of medical stability; the dominant theme was no ventilator changes 1-2 weeks before discharge. Nearly all respondents' institutions (94%) required that caregivers demonstrate independent care; the majority (78.4%) required two trained HMV caregivers. Three-fourths described codified discharge guidelines, including the use of a discharge checklist, assurance of home care, and caregiver training. Respondents described variable difficulty with obtaining durable medical equipment, either because of insurance or durable-medical-equipment company barriers.Conclusions: This national U.S. survey of providers for HMV highlights heterogeneity in practice realities of discharging pediatric patients with HMV. Although no consensus exists, defining medical stability as no ventilator changes 1-2 weeks before discharge was common, as was having an institutional requirement for training two caregivers. Identification of factors driving heterogeneity, data to inform standards, and barriers to implementation are needed to improve outcomes.
