Nearly half of Americans who die in hospitals spend time in the intensive care unit (ICU) in the last 3 days of life. Minority patients who die in the ICU are less likely to formalize advance directives and surviving family members report lower satisfaction with the provision of information and sensitivity to their cultural traditions at the end-of-life. This is a descriptive report of a convenience sample of 157 consecutive patients served by a palliative care team which was integrated into the operations of an ICU at Montefiore Medical Center in the Bronx, New York, from August 2005 until August 2007. The team included an advance practice nurse (APN) and social worker. A separate case-control study was conducted comparing the length of hospital stay for persons who died in the ICU during the final 6 months of the project, prior to and post-palliative care consultation for 22 patients at the hospital campus where the project team was located versus 24 patients at the other campus. Pharmaco-economic data were evaluated for 22 persons who died with and 43 who died without a palliative care consultation at the intervention campus ICU to evaluate whether the project intervention was associated with an increase in the use of pain medications or alterations in the use of potentially non-beneficial life-prolonging treatments in persons dying in the ICU. Data was abstracted from the medical record with a standardized chart abstraction instrument by an unblinded research assistant. Interviews were conducted with a sample of family members and ICU nurses rating the quality of end-of-life care in the ICU with the Quality of Dying and Death in the ICU instrument (ICUQODD), and a family focus group was also conducted. Forty percent of patients were Caucasian, 35% were African American or Afro-Caribbean, 22% Hispanic and 3% were Asian or other. Exploration of the patients' and families' needs identified significant spiritual needs in 62.4% of cases. Education on the death process was provided to 85% of families by the project team. Twenty-nine percent of patients were disconnected from mechanical ventilators following consultation with the Palliative Care Service (PCS), 15.9% of patients discontinued the use of inotropic support, 15.3% stopped artificial nutrition, 6.4% stopped dialysis and 2.5% discontinued artificial hydration. Recommendations on pain management were made for 51% of the project's patients and symptom management for 52% of patients. The project was associated with an increase in the rate of the formalization of advance directives. Thirty-three percent of the patients who received PCS consultations had 'do not resuscitate' orders in place prior to consultation and 83.4% had 'do not resuscitate' orders after the intervention. The project team referred 80 (51%) of the project patients to hospice and 55 (35%) patients were enrolled on hospice, primarily at the medical center. The mean time from admission to palliative care consultation at the project site was 2.8 days versus 15.5 days at the other campus (p = 0....

In an intensive care unit population, the incidence of central venous catheter infection and colonization is low overall and, clinically and statistically, is not different at all three sites when optimal insertion sites are selected, experienced operators insert the catheters, strict sterile technique is present, and trained intensive care unit nursing staff perform catheter care.

Objectives: To assess—by literature review and expert consensus—workforce, workload, and burnout considerations among intensivists and advanced practice providers. Design: Data were synthesized from monthly expert consensus and literature review. Setting: Workforce and Workload section workgroup of the Academic Leaders in Critical Care Medicine Task Force. Measurements and Main Results: Multidisciplinary care teams led by intensivists are an essential component of critical care delivery. Advanced practice providers (nurse practitioners and physician assistants) are progressively being integrated into ICU practice models. The ever-increasing number of patients with complex, life-threatening diseases, concentration of ICU beds in few centralized hospitals, expansion of specialty ICU services, and desire for 24/7 availability have contributed to growing intensivist staffing concerns. Such staffing challenges may negatively impact practitioner wellness, team perception of care quality, time available for teaching, and length of stay when the patient to intensivist ratio is greater than or equal to 15. Enhanced team communication and reduction of practice variation are important factors for improved patient outcomes. A diverse workforce adds value and enrichment to the overall work environment. Formal succession planning for ICU leaders is crucial to the success of critical care organizations. Implementation of a continuous 24/7 ICU coverage care model in high-acuity, high-volume centers should be based on patient-centered outcomes. High levels of burnout syndrome are common among intensivists. Prospective analyses of interventions to decrease burnout within the ICU setting are limited. However, organizational interventions are felt to be more effective than those directed at individuals. Conclusions: Critical care workforce and staffing models are myriad and based on several factors including local culture and resources, ICU organization, and strategies to reduce burden on the ICU provider workforce. Prospective studies to assess and avoid the burnout syndrome among intensivists and advanced practice providers are needed.

Although ultrasound training in vascular access was nearly universal, training in other aspects of ultrasound was less prevalent. We identified several barriers, including fellow turnover, insufficient faculty training, and perceived length of time required for echocardiography training.

SUMMARYPro-inflammatory cytokines, such as tumour necrosis factor ( TNF ) and free radicals, such as nitric oxide ( NO), are mediators of endotoxaemia. Catecholamines are in clinical use to treat the haemodynamic consequences of severe septic shock. Beta-adrenergic agonists exert many of their effects by elevation of intracellular cyclic AMP (cAMP ) concentration. Cyclic AMP can modulate endotoxin-induced cytokine and NO production. Here we investigate the effect of isoproterenol pretreatment on the cytokine and NO production induced by bacterial lipopolysaccharide ( LPS, 4-10 mg/kg). Pretreatment with isoproterenol (10 mg/kg) blunted the LPS-induced TNF response, increased the LPS-induced formation of interleukin-10 and interleukin-6 and reduced the LPSinduced production of NO in conscious mice. In anaesthetized rats, pretreatment with isoproterenol prevented the LPS-induced suppression of vascular contractility to norepinephrine in the thoracic aorta ex vivo. The hyporeactivity is due to expression of the inducible isoform of NO synthase (iNOS) and was restored by in vitro administration of NG-methyl--arginine (-NMA), an inhibitor of NO synthase. However, -NMA did not alter vascular contractility in control vessels or in rings taken from the LPS-treated rats pretreated with isoproterenol. Our findings suggest that, in addition to its haemodynamic actions, isoproterenol may also exert beneficial effects by modulating the endotoxin-induced inflammatory response.

Neurological patients cared for in specialty neuro-ICUs underwent more invasive intracranial and hemodynamic monitoring, tracheostomy, and nutritional support, and received less IV sedation than patients in general ICUs. These differences in care may explain previously observed disparities in outcome between neurocritical care and general ICUs.

The purpose of this study was to examine the impact of nutritional support on nitrogen-energy relationships and functional parameters in malnourished patients with emphysema. Malnourished patients without lung disease served as the control group. Ten ambulatory, stable patients with emphysema and six patients without lung disease received an infusion of 5% dextrose (baseline) plus electrolytes (D5W) for two days, which was followed by an enteral or a parenteral infusion of either a carbohydrate-based (CB, 53% carbohydrate) or a fat-based diet (FB, 55% fat) for 1 wk each, in a randomized cross-over design. All patients had greater than 10% weight loss. Caloric intake was set at 1.7 times the resting energy expenditure (REE) as measured during the baseline period. The REE of patients with emphysema was 23 and 27% above that of the control group during baseline and refeeding periods, respectively. The increased REE was met primarily by an increased carbohydrate oxidation. During the infusion of D5W, N balance was lower in patients with emphysema, but during repletion N balance was similar in both groups of patients. Two weeks of nutritional support with either a CB or a FB diet increased body weight, N balance, and arm muscle area and improved maximal inspiratory pressure, skeletal muscle strength, and endurance-strength (using quadriceps, hamstring, and handgrip) to a similar degree in malnourished patients with and without lung disease. In other stress states, such as infection, it has been shown that hypermetabolism, hypercatabolism, and preferential fat oxidation occur concomitantly. Patients with emphysema are unusual because, although they are hypermetabolic, they are not hypercatabolic and do not demonstrate preferential fat oxidation.
