Noncardiovascular Disease and Critical Care Delivery in a Contemporary Cardiac and Medical Intensive Care Unit.

BACKGROUND: Noncardiovascular comorbidities and critical illness are increasing in cardiovascular intensive care units (CICUs). There are limited data comparing critical care delivery, resource utilization, and costs between contemporary CICUs and medical intensive care units (MICUs). METHODS: All CICU (n = 6967; 22 748 patient-days) and MICU (n = 10 892; 39 211 patient-days) admissions to Cedars-Sinai Medical Center, a tertiary care academic medical center, between January 2011 and December 2016 were reviewed. Both the CICU and MICU admitted patients for primary cardiovascular or medical conditions during the study period, but not for postoperative surgical care. RESULTS: Patients admitted to the CICU were more frequently older, male, and had more preexisting cardiac disease ( P < .0001). More than one-fifth (21.4%) of CICU patients had a noncardiovascular primary admission diagnosis, compared to 89.2% of MICU patients. Cardiovascular intensive care unit patients had lower Acute Physiology and Chronic Health Evaluation III scores (51.1 [19.9] vs 61.1 [24.9], P < .0001) and shorter median hospital length of stay ( P < .001), but not in-unit stay, as compared to MICU patients. Mechanical ventilation, vasopressors, inotropes, renal replacement therapy, and/or blood transfusion were required in 35.0% of CICU patients compared with 62.2% of MICU patients ( P < .0001). The unit mortality rate was lower for CICU than MICU patients (4.8% vs 13.0%, P < .0001), as was the hospital mortality rate (9.3% vs 21.6%, P < .0001). The standardized mortality ratio was 0.73 for the CICU and 0.86 for the MICU. There was no difference in the mean direct cost of care per patient-day between the CICU and MICU ($4011 USD [376] vs $3990 USD [214], P = .77). CONCLUSIONS: The burden of noncardiovascular diseases and the requirement for critical care therapies are high in contemporary CICU patients but remain lower compared to the MICU population. Our findings support the growing complexity of care in tertiary CICUs. Further studies are required to explore the association between critical care delivery and outcomes in this evolving population.

Socioeconomic status and organ damage in Mexican systemic lupus erythematosus women.

The objective of this cross-sectional study was to determine relationships between socioeconomic status and organ damage in Mexican systemic lupus erythematosus (SLE) patients. Demographic and clinical variables were assessed. Socioeconomic status was evaluated using the Graffar method and monthly household income. Lupus activity and organ damage were measured using the SLE disease activity scale, validated for the Mexican population (Mex-SLEDAI), and the Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) scale. The 143 Mexican female SLE patients included (mean age 40.1 ± 8.9 years, mean disease duration 8.9 ± 6.3 years) had a mean monthly household income of $ 407.2 ± 326.5. According to the Graffar index, 18.9%, 52.5%, and 28.7% had high/medium-high, medium, and medium-low/low socioeconomic status, respectively. Organ damage was observed in 61 patients (42.7%). Patients with organ damage had lower monthly household incomes ($241.4 ± 152.4 vs. $354.8 ± 288.3) and were more frequently unemployed (57.3% vs. 35.3%; p = 0.01) than those without. Low monthly income was not associated with lupus activity or self-reported health status. In the adjusted multivariate analysis, low monthly income ( < $300) was associated with organ damage. In conclusion, low income may be associated with organ damage in Mexican SLE patients.

Extended daily on-line high-volume haemodiafiltration in septic multiple organ failure: a well-tolerated and feasible procedure.

BACKGROUND: The outcome of patients with septic multiple organ failure (MOF) remains poor. There are experimental and clinical data indicating a beneficial effect of high-volume haemofiltration. Delivering high-volume therapy is only cost effective using on-line devices because of high costs for additional solution bags in conventional continuous renal replacement therapy (CRRT). We investigated feasibility and effectiveness of extended daily on-line high-volume haemodiafiltration (HDF) with technically maximum convective volume in patients with septic MOF in a pilot study. METHODS: We included 21 consecutive critically ill patients with septic MOF having a mortality risk >50% (SAPS II >50, APACHE II >25). Renal replacement therapy (RRT) was applied with extended daily HDF for 6-23 h using the AK 200 Ultra S dialysis machine in the ultracontrol pre-dilution mode. Dialysate and substitution fluid were prepared on-line. Patients underwent 289 treatments. RESULTS: The mean convective volume was 17.8 ± 3.7 L/h and 208 ± 66 mL/kg/h, respectively, median treatment time was 10:15 h/day. Seventeen of 21 patients survived 28 days (81%). The 90-day survival rate was 52% (11/21) versus 19% compared to the survival rate predicted by APACHE II (33.6 mean) and SAPS II (68.6 mean) scores. Haemodynamics improved significantly during the treatment procedures. Material costs per treatment amounted to 35 €. CONCLUSIONS: Extended daily on-line HDF using maximum convective volume seems to improve the outcome of septic MOF, especially in the early phase. The investigated mode of treatment proved to be feasible, well tolerated and highly cost effective compared to conventional CRRT. At present, this procedure would be applicable at every ICU facility with nephrological support.

A comparison of the hospital costs of open vs. minimally invasive surgical management of necrotizing pancreatitis.

BACKGROUND: Infected necrotizing pancreatitis is a major burden for both the patient and the health care system. Little is known about how hospital costs break down and how they may have shifted with the increasing use of minimally invasive techniques. The aim of this study was to analyse inpatient hospital costs associated with pancreatic necrosectomy. METHODS: A prospective database was used to identify all patients who underwent an intervention for necrotizing pancreatitis. Costs of treatment were calculated using detailed information from the Decision Support Department. Costs for open and minimally invasive surgical modalities were compared. RESULTS: Twelve open and 13 minimally invasive necrosectomies were performed in a cohort of 577 patients presenting over a 50-month period. One patient in each group died in hospital. Overall median stay was 3.8 days in the intensive care unit (ICU) and 44 days on the ward. The median overall treatment cost was US$ 56,674. The median largest contributors to this total were ward (26.3%), surgical personnel (22.3%) and ICU (17.0%) costs. These did not differ statistically between the two treatment modalities. CONCLUSIONS: Pancreatic necrosectomy uses considerable health care resources. Minimally invasive techniques have not been shown to reduce costs. Any intervention that can reduce the length of hospital and, in particular, ICU stay by reducing the incidence of organ failure or by preventing secondary infection is likely to be cost-effective.

[Sepsis in adult patients - definitions, epidemiology and economic aspects]. / Definition, Epidemiologie und ökonomische Aspekte der Sepsis bei Erwachsenen.

Worldwide, sepsis is one of the leading causes of morbidity and mortality. In Germany about 79,000 (116/100,000) suffer from sepsis, and the incidence of severe sepsis and septic shock is about 75,000 cases per year. Patients are at high risk for irreversible organ failure and a lethal course. About 60,000 die from sepsis annually, and survivors have a reduced quality of life. It is presumed that demographic changes will lead to an increased incidence and overall mortality in the future. Additionally sepsis imposes a considerable economic burden to the society. Early and comprehensive treatment significantly improves outcome. An increased knowledge and awareness about the epidemiology, definitions and therapy of sepsis might contribute to the improved outcome. This review aims to present information on current definitions, epidemiology and the economic burden of sepsis.

Drotrecogin alfa's impact on intensive care workload in real life practice: a propensity score approach.

OBJECTIVES: To estimate the impact of drotrecogin alfa (DA) on intensive care workload in an observational study while illustrating the use of propensity score (PS) matching to control for recruitment bias. METHODS: PREMISS is a prospective, multicenter pre-post study. Its goal was to evaluate DA in the treatment of severe sepsis with multiple organ failure. Inclusions took place before (control patients) and after (DA-treated patients) the drug's market authorization. Workload was measured in euros using the French classification of medical procedures. It was compared between the groups via random effects gamma regression using two techniques: 1) regression adjusting for the patients' initial characteristics on the whole population; and 2) PS matching. A structural equation model was used to explore the pathways leading to a workload increase. RESULTS: Drotrecogin alfa is estimated to increase intensive care unit (ICU) workload by 20% (P = 0.045) according to the multivariate model and 34% (P = 0.002) according to the PS-matched one. In the structural equation model fitted, only DA's direct effect on the occurrence of bleeding events reaches significance (P = 0.024). CONCLUSIONS: We found a significant effect of DA on ICU workload with both standard methods of adjustment and PS matching. This effect appears to be mainly due to DA's effect on bleeding events. The analysis illustrated the usefulness of PS methods in the analysis of observational data, as it leads to conclusions similar to the traditional multivariate regression approaches while avoiding making too many adjustments, allowing focusing on the treatment effect.

The budget impact and cost-effectiveness of defibrotide for treatment of veno-occlusive disease with multi-organ dysfunction in patients post-hematopoietic stem cell transplant.

BACKGROUND: A Phase-3 study of defibrotide compared with historical controls demonstrated a 23% improvement in 100-day survival post-hematopoietic stem cell transplantation (HSCT) among patients with veno-occlusive disease with multi-organ dysfunction (VOD with MOD). AIM: To estimate the budget impact and cost-effectiveness of introducing defibrotide to a transplant center. METHODS: The authors developed a budget impact model from the perspective of a bone-marrow transplant center. It was estimated that 2.3% of adults and 4.2% of children would develop VOD with MOD following HSCT based on a retrospective hospital database analysis and the effect that treating patients with defibrotide would have on costs for adult and pediatric centers was estimated. A cost-utility analysis (CUA) was also developed to capture the long-term cost-effectiveness of defibrotide. Projected life expectancies in the two groups were estimated based on trial data, transplant registry data, studies of long-term survival among HSCT patients, and US population life-tables. RESULTS: There was an estimated 3% increase ($330,706) per year in total adult transplantation center costs associated with adopting defibrotide, and a <1% increase ($106,385) for pediatric transplant centers, assuming 100 transplants per year. In the CUA, the lifetime increase in cost per patient was $106,928, life expectancy increased by 3.74 years, and quality-adjusted life-years (QALYs) increased by 2.24. The incremental cost-effectiveness ratio (ICER) was $47,736 per QALY gained; 88% probability defibrotide was cost-effective at a $100,000/QALY threshold. CONCLUSION: The budget impact of defibrotide for a transplant center is relatively modest compared to the overall cost of transplantation. Defibrotide provides an important survival advantage for VOD with MOD patients, and the life years gained lead to defibrotide being highly cost-effective.

Burden of illness associated with sinusoidal obstruction syndrome/veno-occlusive disease in patients with hematopoietic stem cell transplantation.

AIMS: Sinusoidal obstruction syndrome (SOS) is a life-threatening complication of hematopoietic stem cell transplantation (HSCT) associated with significant morbidity and mortality. Healthcare utilization, costs, and mortality were assessed in HSCT patients diagnosed with SOS, with and without multi-organ dysfunction (MOD). MATERIALS AND METHODS: This retrospective observational study identified real-world patients undergoing HSCT between January 1, 2009 and May 31, 2014 using the Premier Healthcare Database. In absence of a formal ICD-9-CM diagnostic code, SOS patients were identified using a pre-specified definition adapted from Baltimore and Seattle criteria and clinical practice. Severe SOS (SOS/MOD) and non-severe SOS (SOS/no-MOD) were classified according to clinical evidence for MOD in the database. RESULTS: Of the 5,418 patients with a discharge diagnosis of HSCT, 291 had SOS, with 134 categorized as SOS/MOD and 157 as SOS/no-MOD. The remaining 5,127 patients had HSCT without SOS. Overall SOS incidence was 5.4%, with 46% having evidence of MOD. Distribution of age, gender, and race were similar between the SOS cohorts and non-SOS patients. After controlling for hospital profile and admission characteristics, demographics, and clinical characteristics, the adjusted mean LOS was 31.0 days in SOS/MOD compared to 23.9 days in the non-SOS cohort (medians = 26.9 days vs 20.8 days, p < .001). The adjusted mean cost of SOS/MOD patients was $140,653, which was $41,702 higher than the non-SOS cohort (medians = $105,749 vs $74,395, p < .001). An almost 6-fold increased odds of inpatient mortality was associated with SOS/MOD compared to the non-SOS cohort (odds ratio = 5.88; 95% CI = 3.45-10.33). LIMITATIONS: Limitations of retrospective observational studies apply, since the study was not randomized. Definition for SOS was based on ICD-9 diagnosis codes from a hospital administrative database and reliant on completeness and accuracy of coding. CONCLUSIONS: Analysis of real-world data shows that SOS/MOD is associated with significant increases in healthcare utilization, costs, and inpatient mortality.

The burden of nosocomial infection in the intensive care unit: Effects on organ failure, mortality and costs. A nested case-control study.

BACKGROUND: Nosocomial infections increase mortality and costs in the intensive care units; however, few studies have addressed organ failure that developed in infected patients and their overall costs. The goal of this study was to measure the frequency of organ failure in nosocomial infection and the mortality and costs of these in critical care areas. METHODS: This was a nested 1:2 case-control study in a cohort of all consecutively hospitalized patients comparing those with and without nosocomial infections over a year in an institutional intensive care unit (ICU). Those patients who acquired an infection during hospitalization were considered cases. Controls were matched by hospital stay at least as long as the cases' time acquisition of nosocomial infection, age +/-5 years and APACHE II +/-5 points. RESULTS: Forty-three patients developed at least one nosocomial infection event (cases). The matching success was about 94%. Higher frequency and duration of organ failures was observed in the cases, as well as the number of devices and procedures (p < 0.05). Attributable mortality was 16.3% (p < 0.001). Attributable total cost of a nosocomial infection acquired in the ICU was 12,155 dollars. CONCLUSIONS: Nosocomial infection acquired in the ICU increases length of stay, frequency and duration of organ failures, mortality, and costs.

Analysis of resource use and cost-generating factors in a German medical intensive care unit employing the Therapeutic Intervention Scoring System (TISS-28).

OBJECTIVE: Evaluation of resource use and costs of a medical intensive care unit (ICU) utilising the simplified Therapeutic Intervention Scoring System (TISS-28). DESIGN: Prospective observational study. SETTING: : Medical ICU of a tertiary care centre. PATIENTS: Consecutive patients with an ICU length of stay (LOS) more than 24 h. INTERVENTIONS: Over a 3 month period SAPS II, TISS-28 and SOFA were determined daily. Patients were retrospectively classified as receiving active (AT) or non-active (NAT) treatment according to TISS-28 variables, with AT representing a therapeutic intervention that could not be performed outside the ICU. Individual expenditure for all patients was calculated using a modified 'top-down' method. MEASUREMENTS AND RESULTS: Out of 303 consecutive patients, 241 (79.5%), including all non-survivors, were categorised AT. The hospital mortality was 14.5%. TISS-28 and ICU LOS were higher in patients receiving AT ( p<0.001). Patient-specific costs accounted for 36 EUR per TISS-point and daily treatment costs 1336 EUR for all patients. Daily costs of care were 68 EUR higher for AT, compared to NAT, patients ( p<0.001). There was no association between ICU costs and measures of severity of illness (SAPS II, SOFA). CONCLUSIONS: TISS-28 is a fast, reliable and readily applicable tool to identify patients receiving AT. Although total and daily costs of care were significantly higher in patients receiving AT, the difference of the daily costs was, albeit statistically significant, economically negligible. The main difference in ICU costs was attributable to ICU LOS. Therefore cost-saving strategies must aim at reducing ICU LOS, without compromising quality of care.

Intra-operative gut mucosal hypoperfusion is associated with increased post-operative complications and cost.

OBJECTIVES: To determine CO and gastric mucosal perfusion in patients during elective major surgery; to seek a relationship with subsequent outcome. DESIGN: Prospective descriptive study. SETTING: University hospital. PATIENTS: 51 patients undergoing elective major surgery of an anticipated duration of greater than 2 h who were at risk of developing gut mucosal hypoperfusion and postoperative organ failure. MEASUREMENTS AND RESULTS: CO was determined by oesophageal Doppler measurement of aortic blood flow. Gastric mucosal perfusion was determined by tonometric assessment of gastric mucosal pH (pHi). Blood pressure and urine flow were measured. At the end of surgery no patients were oliguric or hypotensive. Post-operatively morbidity, mortality, duration and cost of stay in the ITU and hospital were assessed. There were 32 patients with evidence of gastric mucosal ischaemia at the end of surgery (pHi < 7.32) despite maintenance of CO. This group of patients spent a mean of 4.7 (range 0-33) days in the ITU, 14 developed major complications (7 with multiple organ failure [MOF] and 6 died. In 19 patients gut mucosal perfusion was maintained during surgery (pHi > or = 7.32); these patients demonstrated an increase in CO of 48.4% (95% confidence interval 21.3 -75.6) and spent a mean of 1.0 (range 0-4) days in the ITU. Only one developed a major complication and none died. The total cost of post-operative care for the 51 patients was estimated at pounds 356650. Mean cost per patient in the low pHi group was significantly greater at pounds 8845 (range pounds 600--pounds 42,700) compared to pounds 3874 (range pounds 2,600--pounds 9,600) in the normal pHi group. The total.cost of post-operative care for the 7 patients who developed MOF was pounds 171,450 i.e. 48% of the total cost. CONCLUSION: A low gastric pHi measured during the intraoperative period in a group of patients undergoing major (mainly cardiovascular) surgery is associated with increased post-operative complications and cost.

Long-term survival and quality of life in cardiac surgical patients with prolonged intensive care unit length of stay.

BACKGROUND: Patients with prolonged intensive care unit (ICU) stays after cardiac operations are labor intensive and expensive. We sought to determine whether exhaustive ICU efforts result in survival or quality-of-life benefits and whether outcome could be predicted. METHODS: We retrospectively analyzed all adult cardiac surgical patients in 1998 for ICU stays more than 14 days. Data were analyzed to create multiple organ dysfunction scores (MODS, range 0 to 24) and hospital charges. Follow-up was conducted 1 and 2 years apart for survival and quality-of-life evaluation. RESULTS: Forty-nine patients remained in the ICU more than 14 days, comprising 3.8% of our patients but 28% of total ICU bed time. This population had a 28.5% hospital mortality, which was greater than those in the ICU less than 14 days (5.3%, p < 0.05). By 2 years, 22 of the 35 discharged patients were alive, 16 of whom had a normal quality of life. Patients alive at 2 years had lower MODS at day 14 than those who died (2.6 +/- 1.4 versus 5.5 +/- 3.8; p < 0.005) as well as lower hospital costs ($223,000 +/- $128,000 versus $306,000 +/- $128,000; p < 0.05). No patient with an MODS of at least 6 at day 14 survived. CONCLUSIONS: Patients remaining in the ICU for more than 14 days suffer a higher mortality at greater expense. A MODS at day 14 may help predict those who will not enjoy long-term survival and thus aid in the decision to terminate care.

An evaluation of the cost effectiveness of drotrecogin alfa (activated) relative to the number of organ system failures.

BACKGROUND: While drotrecogin alfa (activated) was shown to decrease absolute 28-day mortality by 6.1% in patients with severe sepsis in the Recombinant Human Protein C Worldwide Evaluation in Severe Sepsis (PROWESS) study, no mortality benefit was observed in the subset of patients with only one organ system failure. Consequently, some institutions restrict drotrecogin alfa (activated) use to patients with severe sepsis with >/=2 organ system failures. OBJECTIVE: To measure the cost effectiveness of drotrecogin alfa (activated) for treatment of severe sepsis in relation to the number of organ system failures and determine the economic impact of restricting drotrecogin alfa (activated) use based on the number of organ system failures. PERSPECTIVE: Policy perspective specific to our 340-bed, level I trauma centre. METHODS: A Monte Carlo simulation analysis was conducted to evaluate a hypothetical cohort of 10 000 patients with severe sepsis in four scenarios restricting treatment with drotrecogin alfa (activated) to patients with >/=1, >/=2, >/=3 or >/=4 organ system failures. The primary outcomes of 28-day all-cause mortality and serious bleeding were obtained from the PROWESS study. Costs (year 2002 values) were obtained from institutional financial records and literature estimates. The incremental cost per life saved at 28 days with drotrecogin alfa (activated) plus best standard care versus best standard care alone (placebo) was calculated. The incidence of severe sepsis and number of drotrecogin alfa (activated) candidates were estimated through chart review, and projected annual institutional expenditures were derived according to these data. RESULTS: With increasing number of organ system failures, the proportion of lives saved with drotrecogin alfa (activated) increased, and consequently the ICER decreased. Restriction of drotrecogin alfa (activated) to patients with >/=4 organ system failures was the most cost-effective scenario (0.11 lives saved; 56727 US dollars per life saved). For the nine patients that would be treated annually by our institution under this policy, one life would be saved at a total additional cost of 56160 US dollars per year. Use of the drug in patients with >/=1 or >/=2 organ system failures would save the greatest number of lives per year (4-5); however, restricting drotrecogin alfa (activated) to patients with >/=2 organ system failures would be the cheaper alternative (total additional cost 356022 US dollars vs 462204 US dollars . CONCLUSION: While restriction of drotrecogin alfa (activated) use to patients with sepsis with >/=4 organ system failures is the most cost-effective alternative, restriction to those with >/=2 organ system failures is the preferred alternative for our institution according to the number of lives saved and available financial resources.

[Use of portable computed tomography in non-transportable patients on the intensive care unit: preclinical experience]. / Einsatz der mobilen Computertomographie bei nicht transportfähigen Patienten auf der Intensivstation - Ein Erfahrungsbericht.

PURPOSE: To evaluate different concepts of the application of a portable CT (PCT) directly in a patient's ICU room versus in a specially designed interventional suite (IS). METHODS: 13 patients with maximum ICU treatment were examined by PCT and assessed with regard to their health status by ICU scores (TISS 28, MODS). Only patients with a therapeutic intervention scoring system 28 (TISS 28) value of 40 or greater were included in the study. A TISS 28 value of 40 or more characterizes a patient requiring maximal ICU treatment. Patients were examined by PCT either in the patient's room or in the IS on the ICU. Scanning time and personnel resource expense were determined. The multiple organ dysfunction score (MODS) was utilized for patient characterization. RESULTS: An average of 1.4 hours was needed to perform a PCT scan in the interventional room. A minimum of 4.5 hours or up to a maximum of 7.2 hours were required to perform a bedside scan in the patient's room. There is a noticeable difference between patients with respect to TISS 28. Patients examined by bedside CT were more acutely ill than the others by reason of MODS (8 - 18 patient-room group vs. 3 - 12 IS group). CONCLUSIONS: PCT performed on an ICU assures optimal treatment of patients during CT examination. Portable CT had more time exposure and required more personnel resources than examination in the IS. All PCT examinations performed directly in the patient's room demonstrated the diagnostic value and had direct therapeutic consequences.

[Survival and quality of life of patients with multiple organ failure one year after leaving an intensive care unit]. / Supervivencia y calidad de vida de los pacientes con fracaso multiorgánico al año del alta de una unidad de medicina intensiva.

BACKGROUND: The patients' mortality with multiple organ failure (MOF) is very high and patients who consume the most resources are those with uncertain prognosis. In order to use the limited resources adequately, it is necessary to know the cost-benefit relationship of their treatment and in this study cost, mortality, quality of life (QOL) of survivors who developed MOF has been investigated. PATIENTS AND METHODS: Mortality in the Intensive Care Unit (ICU) and mortality QOL (with modified EuroQOL Instrument) one year after discharge were studied in 239 admitted patients who developed MOF. Cost was estimated from administrative dats of cost patients-day. To determine mortality independent predicting factors, a logistic regression model was used. RESULTS: Of the 239 patients studied, 144 (60%) died in ICU and 29 (12%) died after discharge. The independent predicting factors of mortality one year after discharge from ICU were: age (p < 0.1, odds ratio [OR] = 1.02), cardiac surgery (p < 0.0000, OR = 0.1899) and trauma (p < 0.05, OR = 0.2287). Of the 66 surviving patients, 18% were severely discapacitated. Forty one percent recovered their previous QOL, 18% improved it and 39% got worse. Patients with MOF consumed 64% of ICU total resources and of these, 77% was consumed by patients who died and by severely discapacitated. CONCLUSION: A high proportion of resources were used by MOF patients, but patients who died and who remained with worst QOL consumed the highest part. Although the mortality after one year was high (72%), 80% of the survivors achieved an acceptable QOL and for this reason, treatment of these patients should not be limited if survival and QOL predictions are not 100% correct.

[Medical, ethical and economical limitations in the treatment of multitrauma patients]. / Grenzen der Behandlung Schwerstverletzter.

In the early post-traumatic period severe traumatic brain injuries and massive bleeding from disrupted parenchymal organs, large vessels or crush injuries of the pelvis may present as morphological damage that renders survival impossible, although aggressive fluid and blood replacement therapy in conjunction with immediately stopping blood loss surgically may result in survival in selected cases. In contrast, late mortality from multiple organ failure - which in the past limited survival in 10 to 30 % of patients in that condition - has in recent years reduced this as the cause of death to less than 5 %. Part of the responsibility of the surgeon caring for the severely injured into consider the ethical limitations to avoid futile use of the sophisticated life-support measures in the intensive care setting. A threat to optimal care of the severely injured patient may arise from the economical restraints imposed on health-care providers. When one considers the enormous political and socioeconomical importance of rehabilitating the predominantly young trauma patients and reintegrating them into the work world, an appeal has to be made to all those responsible to secure optimal care for severely injured patients in the future.

Temporal trends of postinjury multiple-organ failure: still resource intensive, morbid, and lethal.

BACKGROUND: While the incidence of postinjury multiple-organ failure (MOF) has declined during the past decade, temporal trends of its morbidity, mortality, presentation patterns, and health care resources use have been inconsistent. The purpose of this study was to describe the evolving epidemiology of postinjury MOF from 2003 to 2010 in multiple trauma centers sharing standard treatment protocols. METHODS: "Inflammation and Host Response to Injury Collaborative Program" institutions that enrolled more than 20 eligible patients per biennial during the 2003 to 2010 study period were included. The patients were aged 16 years to 90 years, sustained blunt torso trauma with hemorrhagic shock (systolic blood pressure < 90 mm Hg, base deficit ≥ 6 mEq/L, blood transfusion within the first 12 hours), but without severe head injury (motor Glasgow Coma Scale [GCS] score < 4). MOF temporal trends (Denver MOF score > 3) were adjusted for admission risk factors (age, sex, body max index, Injury Severity Score [ISS], systolic blood pressure, and base deficit) using survival analysis. RESULTS: A total of 1,643 patients from four institutions were evaluated. MOF incidence decreased over time (from 17% in 2003-2004 to 9.8% in 2009-2010). MOF-related death rate (33% in 2003-2004 to 36% in 2009-2010), intensive care unit stay, and mechanical ventilation duration did not change over the study period. Adjustment for admission risk factors confirmed the crude trends. MOF patients required much longer ventilation and intensive care unit stay, compared with non-MOF patients. Most of the MOF-related deaths occurred within 2 days of the MOF diagnosis. Lung and cardiac dysfunctions became less frequent (57.6% to 50.8%, 20.9% to 12.5%, respectively), but kidney and liver failure rates did not change (10.1% to 12.5%, 15.2% to 14.1%). CONCLUSION: Postinjury MOF remains a resource-intensive, morbid, and lethal condition. Lung injury is an enduring challenge and should be a research priority. The lack of outcome improvements suggests that reversing MOF is difficult and prevention is still the best strategy. LEVEL OF EVIDENCE: Epidemiologic study, level III.

Cost effectiveness of drotrecogin alfa (activated) for the treatment of severe sepsis in the United Kingdom.

Drotrecogin alfa (activated) is licensed in Europe for the treatment of severe sepsis in patients with multiple organ failure. We constructed a model to assess the cost effectiveness of drotrecogin alfa (activated) from the perspective of the UK National Health Service when used in adult intensive care units. Patient outcomes from a 28-day international clinical trial (PROWESS) and a subsequent follow-up study (EVBI) were supplemented with UK data. Cost effectiveness was assessed as incremental cost per life year and per quality adjusted life year saved compared to placebo alongside best usual care. Applying the 28-day mortality outcomes of the PROWESS study, the model produced a cost per life year saved of 4608 UK pounds and cost per quality adjusted life year saved of 6679 UK pounds. Equivalent results using actual hospital outcomes were 7625 UK pounds per life year and 11,051 UK pounds per quality adjusted life year. Drotrecogin alfa (activated) appears cost effective in treating severe sepsis in UK intensive care units.
