During October 2010–July 2011, 1.0% of pandemic (H1N1) 2009 viruses in the United States were oseltamivir resistant, compared with 0.5% during the 2009–10 influenza season. Of resistant viruses from 2010–11 and 2009–10, 26% and 89%, respectively, were from persons exposed to oseltamivir before specimen collection. Findings suggest limited community transmission of oseltamivir-resistant virus.
Avoiding or limiting contact with swine at agricultural events may help prevent A(H3N2)v virus infections in such settings.
IMPORTANCEFor critically ill patients with advanced medical illnesses and poor prognoses, overuse of invasive intensive care unit (ICU) treatments may prolong suffering without benefit.OBJECTIVE To examine whether use of time-limited trials (TLTs) as the default care-planning approach for critically ill patients with advanced medical illnesses was associated with decreased duration and intensity of nonbeneficial ICU care. DESIGN, SETTING, AND PARTICIPANTSThis prospective quality improvement study was conducted from June 1, 2017, to December 31, 2019, at the medical ICUs of 3 academic public hospitals in California. Patients at risk for nonbeneficial ICU treatments due to advanced medical illnesses were identified using categories from the Society of Critical Care Medicine guidelines for admission and triage. INTERVENTIONS Clinicians were trained to use TLTs as the default communication and care-planning approach in meetings with family and surrogate decision makers. MAIN OUTCOMES AND MEASURES Quality of family meetings (process measure) and ICU length of stay (clinical outcome measure). RESULTS A total of 209 patients were included (mean [SD] age, 63.6 [16.3] years; 127 men [60.8%]; 101 Hispanic patients [48.3%]), with 113 patients (54.1%) in the preintervention period and 96 patients (45.9%) in the postintervention period. Formal family meetings increased from 68 of 113 (60.2%) to 92 of 96 (95.8%) patients between the preintervention and postintervention periods (P < .01). Key components of family meetings, such as discussions of risks and benefits of ICU treatments (preintervention, 15 [34.9%] vs postintervention, 56 [94.9%]; P < .01), eliciting values and preferences of patients (20 [46.5%] vs 58 [98.3%]; P < .01), and identifying clinical markers of improvement (9 [20.9%] vs 52 [88.1%]; P < .01), were discussed more frequently after intervention. Median ICU length of stay was significantly reduced between preintervention and postintervention periods (8.7 [interquartile range (IQR), 5.7-18.3] days vs 7.4 [IQR, 5.2-11.5] days; P = .02). Hospital mortality was similar between the preintervention and postintervention periods (66 of 113 [58.4%] vs 56 of 96 [58.3%], respectively; P = .99). Invasive ICU procedures were used less frequently in the postintervention period (eg, mechanical ventilation preintervention, 97 [85.8%] vs postintervention, 70 [72.9%]; P = .02). CONCLUSIONS AND RELEVANCEIn this study, a quality improvement intervention that trained physicians to communicate and plan ICU care with family members of critically ill patients in the ICU using TLTs was associated with improved quality of family meetings and a reduced intensity and duration of ICU treatments. This study highlights a patient-centered approach for treating critically ill patients that may reduce nonbeneficial ICU care.
BackgroundPneumonia poses a significant burden to the U.S. health-care system. However, there are few data focusing on severe pneumonia, particularly cases of pneumonia associated with specialized care in intensive care units (ICU).MethodsWe used administrative and electronic medical record data from six integrated health care systems to estimate rates of pneumonia hospitalizations with ICU admissions among adults during 2006 through 2010. Pneumonia hospitalization was defined as either a primary discharge diagnosis of pneumonia or a primary discharge diagnosis of sepsis or respiratory failure with a secondary diagnosis of pneumonia in administrative data. ICU admissions were collected from internal electronic medical records from each system. Comorbidities were identified by ICD-9-CM codes coded during the current pneumonia hospitalization, as well as during medical visits that occurred during the year prior to the date of admission.ResultsWe identified 119,537 adult hospitalizations meeting our definition for pneumonia. Approximately 19% of adult pneumonia hospitalizations had an ICU admission. The rate of pneumonia hospitalizations requiring ICU admission during the study period was 76 per 100,000 population/year; rates increased for each age-group with the highest rates among adults aged ≥85 years. Having a co-morbidity approximately doubled the risk of ICU admission in all age-groups.ConclusionsOur study indicates a significant burden of pneumonia hospitalizations with an ICU admission among adults in our cohort during 2006 through 2010, especially older age-groups and persons with underlying medical conditions. These findings reinforce current strategies aimed to prevent pneumonia among adults.Electronic supplementary materialThe online version of this article (10.1186/s12890-017-0552-x) contains supplementary material, which is available to authorized users.
