Trends in Mortality and Medical Spending in Patients Hospitalized for Community-Acquired Pneumonia: 1993–2005

Background: Community-acquired pneumonia (CAP) is the most common infectious cause of death in the United States. To understand the impact of efforts to improve quality and efficiency of care in CAP, we examined trends in mortality and costs among hospitalized CAP patients. Methods: Using the National Inpatient Sample from 1993–2005, we studied 569,524 CAP admissions. The primary outcome was mortality at discharge. We used logistic regression to evaluate the mortality trend, adjusting for age, gender, and comorbidities. To account for the impact of early discharge practices, we also compared daily mortality rates and performed a Cox proportional-hazards model. We used a generalized linear model to analyze trends in hospitalization costs, which were derived using cost-to-charge ratios. Results: Over time, length of stay (LOS) declined, while more patients were discharged to other facilities. The frequency of many comorbidities increased. Age/gender-adjusted mortality decreased from 8.9% to 4.1% (P < 0.001). In multivariable analysis, the mortality risk declined through 2005 (odds ratio, 0.50; 95% confidence interval [CI], 0.48–0.53), compared to reference year 1993. The daily mortality rates demonstrated that most of the mortality reduction occurred early during hospitalization. After adjusting for early discharge practices, the risk of mortality still declined through 2005 (hazard ratio, 0.74, 95% CI 0.70–0.78). Median hospitalization costs exhibited a modest reduction over time, mostly due to reduced LOS. Conclusions: Mortality among patients hospitalized for CAP has declined. Lower in-hospital mortality at a reduced cost suggests that pneumonia is a case of improved productivity in health care.Economic

Communication media and the dead:from the Stone Age to Facebook

This article argues as follows: (i) The presence of the dead within a society depends in part on available communication technologies, specifically speech, stone, sculpture, writing, printing, photography and phonography (including the mass media), and most recently the internet. (ii) Each communication technology affords possibilities for the dead to construct and legitimate particular social groups and institutions – from the oral construction of kinship, to the megalithic legitimation of the territorial rights of chiefdoms, to the written word’s construction of world religions and nations, to the photographic and phonographic construction of celebrity-based neo-tribalism, and to the digital reconstruction of family and friendship. (iii) Historically, concerns about the dead have on a number of occasions aided the development of new communication technologies – the causal connection between the two can go both ways. The argument is based primarily on critical synthesis of existing research literature

Hyperoxemia and excess oxygen use in early acute respiratory distress syndrome : Insights from the LUNG SAFE study

Publisher Copyright: © 2020 The Author(s). Copyright: Copyright 2020 Elsevier B.V., All rights reserved.Background: Concerns exist regarding the prevalence and impact of unnecessary oxygen use in patients with acute respiratory distress syndrome (ARDS). We examined this issue in patients with ARDS enrolled in the Large observational study to UNderstand the Global impact of Severe Acute respiratory FailurE (LUNG SAFE) study. Methods: In this secondary analysis of the LUNG SAFE study, we wished to determine the prevalence and the outcomes associated with hyperoxemia on day 1, sustained hyperoxemia, and excessive oxygen use in patients with early ARDS. Patients who fulfilled criteria of ARDS on day 1 and day 2 of acute hypoxemic respiratory failure were categorized based on the presence of hyperoxemia (PaO2 > 100 mmHg) on day 1, sustained (i.e., present on day 1 and day 2) hyperoxemia, or excessive oxygen use (FIO2 ≥ 0.60 during hyperoxemia). Results: Of 2005 patients that met the inclusion criteria, 131 (6.5%) were hypoxemic (PaO2 < 55 mmHg), 607 (30%) had hyperoxemia on day 1, and 250 (12%) had sustained hyperoxemia. Excess FIO2 use occurred in 400 (66%) out of 607 patients with hyperoxemia. Excess FIO2 use decreased from day 1 to day 2 of ARDS, with most hyperoxemic patients on day 2 receiving relatively low FIO2. Multivariate analyses found no independent relationship between day 1 hyperoxemia, sustained hyperoxemia, or excess FIO2 use and adverse clinical outcomes. Mortality was 42% in patients with excess FIO2 use, compared to 39% in a propensity-matched sample of normoxemic (PaO2 55-100 mmHg) patients (P = 0.47). Conclusions: Hyperoxemia and excess oxygen use are both prevalent in early ARDS but are most often non-sustained. No relationship was found between hyperoxemia or excessive oxygen use and patient outcome in this cohort.

Diagnosing sepsis is subjective and highly variable: a survey of intensivists using case vignettes

Background: Sepsis is the focus of national quality improvement programs and a recent public reporting measure from the Centers for Medicare and Medicaid Services. However, diagnosing sepsis requires interpreting nonspecific signs and can therefore be subjective. We sought to quantify interobserver variability in diagnosing sepsis. Methods: We distributed five case vignettes of patients with suspected or confirmed infection and organ dysfunction to a sample of practicing intensivists. Respondents classified cases as systemic inflammatory response syndrome, sepsis, severe sepsis, septic shock, or none of the above. Interobserver variability was calculated using Fleiss’ κ for the five-level classification, and for answers dichotomized as severe sepsis/septic shock versus not-severe sepsis/septic shock and any sepsis category (sepsis, severe sepsis, or septic shock) versus not-sepsis. Results: Ninety-four physicians completed the survey. Most respondents (88 %) identified as critical care specialists; other specialties included pulmonology (39 %), anesthesia (19 %), surgery (9 %), and emergency medicine (9 %). Respondents had been in practice for a median of 8 years, and 90 % practiced at academic hospitals. Almost all respondents (83 %) felt strongly or somewhat confident in their ability to apply the traditional consensus sepsis definitions. However, overall interrater agreement in sepsis diagnoses was poor (Fleiss’ κ 0.29). When responses were dichotomized into severe sepsis/septic shock versus not-severe sepsis/septic shock or any sepsis category versus not-sepsis, agreement was still poor (Fleiss’ κ 0.23 and 0.18, respectively). Seventeen percent of respondents classified one of the five cases as severe sepsis/septic shock, 27.7 % rated two cases, 33.0 % respondents rated three cases, 19.2 % rated four cases, and 3.2 % rated all five cases as severe sepsis/septic shock. Among respondents who felt strongly confident in their ability to use sepsis definitions (n = 45), agreement was no better (Fleiss’ κ 0.28 for the five-category classification, and Fleiss’ κ 0.21 for the dichotomized severe sepsis/septic shock classification). Cases were felt to be extremely or very realistic in 74 % of responses; only 3 % were deemed unrealistic. Conclusions: Diagnosing sepsis is extremely subjective and variable. Objective criteria and standardized methodology are needed to enhance consistency and comparability in sepsis research, surveillance, benchmarking, and reporting.

An exploration of safety climate in nursing homes

OBJECTIVES: Although nursing homes provide complex care requiring attention to safety, research on safety climate in nursing homes is limited. Our study assessed differences in attitudes about safety among nursing home personnel and piloted a new survey, specifically designed for the nursing home context. METHODS: Drawing on previous safety climate surveys for hospitals and nursing homes, researchers developed the Survey on Resident Safety in Nursing Homes and administered it March to June 2008 to frontline caregivers and managers in 8 randomly selected Massachusetts nursing homes. Our sample consisted of 751 employees, including all full-time, direct-care staff and managers from participating facilities. First, we performed factor analysis and determined Cronbach alphas for the Survey on Resident Safety in Nursing Homes. Then, we described facilities\u27 safety climate and variation by personnel category and among facilities by calculating the proportion of responses that were strongly positive by item, personnel category, and nursing home. RESULTS: Of 432 respondents (57% response), 29% gave their nursing home an excellent rating overall. Scores varied by personnel category and home: 51% of senior managers gave an excellent safety grade versus 26% of nursing assistants; the range in top safety grades among nursing homes was 30 percentage points. CONCLUSIONS: Safety climate varied substantially among this small sample of nursing homes and by personnel category; managers had more positive perceptions about safety than frontline workers. Efforts to measure safety climate in nursing homes should include the full range of staff at a facility and comparisons among staff categories to provide a full understanding for decision making and to promote targeted response to improve resident safety
