    ABSTRACT: ABSTRACT CONTEXT: Critically ill, morbidly obese patients, (BMI ≥40) are at high risk of respiratory failure requiring invasive mechanical ventilation (IMV). It is not clear if outcomes of critically ill obese patients are affected by obesity. Due to limited cardio-pulmonary reserve they may also have poor outcomes. However, literature to this effect is limited and conflicted. OBJECTIVE: We used Nationwide Inpatient Sample from 2004 to 2008 to examine the outcomes of morbidly obese persons receiving IMV and compared them to non-obese persons. We identified hospitalizations requiring IMV and morbid obesity using ICD9CM codes. Primary outcomes studied were in-hospital mortality, rates of prolonged mechanical ventilation (≥96hrs) and tracheostomy. Multivariable logistic regression was used to adjust for potential confounding variables. We also examined outcomes stratified by number of organs failing. RESULTS: Of all hospitalized morbidly obese persons, 2.9% underwent IMV. Mean age, co-morbidity score and severity of illness were lower in morbidly obese persons. The adjusted mortality was not significantly different in morbidly obese persons (OR 0.89; 95%CI: 0.74 to 1.06). When stratified by severity of disease, there was a stepwise increase in risk of mortality amongst morbidly obese persons - 0.77 (95% CI 0.58 to 1.01) for only respiratory failure to OR 4.14 (95% CI 1.11 to 15.3) for ≥4 organs failing. Rates of prolonged mechanical ventilation was similar, but rate of tracheostomy (OR 2.19; 95% CI 1.77 to 2.69) were significantly higher in the morbidly obese. CONCLUSION: Morbidly obese persons undergoing IMV have similar risk of death than non obese persons if only respiratory failure is present. When more organs fail, they have increased mortality.

    ABSTRACT: Deteriorating ward patients are at increased risk. Electronic automated advisory vital signs monitors may help identify such patients and improve their outcomes. A total of 349 beds, in 12 general wards in ten hospitals in the United States, Europe, and Australia. Cohort of 18,305 patients. Before-and-after controlled trial. We deployed electronic automated advisory vital signs monitors to assist in the acquisition of vital signs and calculation of early warning scores. We assessed their effect on frequency, type, and treatment of rapid response team calls; survival to hospital discharge or to 90 days for rapid response team call patients; overall type and number of serious adverse events and length of hospital stay. We studied 9,617 patients before (control) and 8,688 after (intervention) deployment of electronic automated advisory vital signs monitors. Among rapid response team call patients, intervention was associated with an increased proportion of calls secondary to abnormal respiratory vital signs (from 21% to 31%; difference [95% confidence interval] 9.9 [0.1-18.5]; p=.029). Survival immediately after rapid response team treatment and survival to hospital discharge or 90 days increased from 86% to 92% (difference [95% confidence interval] 6.3 [0.0-12.6]; p=.04). Intervention was also associated with a decrease in median length of hospital stay in all patients (unadjusted p<.0001; adjusted p=.09) and more so in U.S. patients (from 3.4 to 3.0 days; unadjusted p<.0001; adjusted ratio [95% confidence interval] 1.03 [1.00-1.06]; p=.026). The time required to complete and record a set of vital signs decreased from 4.1±1.3 mins to 2.5±0.5 mins (difference [95% confidence interval] 1.6 [1.4-1.8]; p<.0001). Deployment of electronic automated advisory vital signs monitors was associated with an improvement in the proportion of rapid response team-calls triggered by respiratory criteria, increased survival of patients receiving rapid response team calls, and decreased time required for vital signs measurement and recording (NCT01197326).

    ABSTRACT: Violence in the health care workplace is occurring in a covert fashion; it is occurring at the patient bedside. However, data on workplace violence tend to be underreported and relatively scarce. This article identifies and examines the phenomenon of unreported and underreported workplace violence against nursing staff that is virtually hidden. Health care executives need to be attuned to this type of violence because it may significantly affect their ability to recruit and retain nursing staff. This article provides a synthesis of literature and data from health services administration and nursing and human resources, as well as the experience of the first author. Workplace violence in health care is a critical issue that must be addressed from legal, financial, ethical, and human resources management perspectives. It is a problem for staff providing direct care services to patients with Alzheimer disease. This article suggests strategies and offers a framework for meeting the challenges of managing hidden workplace violence. In addition to the more discrete consequences of violence including physical injury, physical disability, trauma, or even death, the complementary organizational effects call for thoughtful managerial planning and critical thinking. Guidelines for preventing and addressing workplace violence in health care organizations are also published by the Occupational Safety and Health Administration.
