BACKGROUND: Alternative therapies for Staphylococcus aureus bacteremia and endocarditis are needed. METHODS: We randomly assigned 124 patients with S. aureus bacteremia with or without endocarditis to receive 6 mg of daptomycin intravenously per kilogram of body weight daily and 122 to receive initial low-dose gentamicin plus either an antistaphylococcal penicillin or vancomycin. The primary efficacy end point was treatment success 42 days after the end of therapy. RESULTS: Forty-two days after the end of therapy in the modified intention-to-treat analysis, a successful outcome was documented for 53 of 120 patients who received daptomycin as compared with 48 of 115 patients who received standard therapy (44.2 percent vs. 41.7 percent; absolute difference, 2.4 percent; 95 percent confidence interval, -10.2 to 15.1 percent). Our results met prespecified criteria for the noninferiority of daptomycin. The success rates were similar in subgroups of patients with complicated bacteremia, right-sided endocarditis, and methicillin-resistant S. aureus. Daptomycin therapy was associated with a higher rate of microbiologic failure than was standard therapy (19 vs. 11 patients, P=0.17). In 6 of the 19 patients with microbiologic failure in the daptomycin group, isolates with reduced susceptibility to daptomycin emerged; similarly, a reduced susceptibility to vancomycin was noted in isolates from patients treated with vancomycin. As compared with daptomycin therapy, standard therapy was associated with a nonsignificantly higher rate of adverse events that led to treatment failure due to the discontinuation of therapy (17 vs. 8, P=0.06). Clinically significant renal dysfunction occurred in 11.0 percent of patients who received daptomycin and in 26.3 percent of patients who received standard therapy (P=0.004). CONCLUSIONS: Daptomycin (6 mg per kilogram daily) is not inferior to standard therapy for S. aureus bacteremia and right-sided endocarditis.

The patient-centered medical home (PCMH) is emerging as a potential catalyst for multiple health care reform efforts. Demonstration projects are beginning in nearly every state, with a broad base of support from employers, insurers, state and federal agencies, and professional organizations. A sense of urgency to show the feasibility of the PCMH, along with a 3-tiered recognition process of the National Committee on Quality Assurance, are influencing the design and implementation of many demonstrations. In June 2006, the American Academy of Family Physicians launched the first National Demonstration Project (NDP) to test a model of the PCMH in a diverse national sample of 36 family practices. The authors make up an independent evaluation team for the NDP that used a multimethod evaluation strategy, including direct observation, in-depth interviews, chart audit, and patient and practice surveys. Early lessons from the real-time qualitative analysis of the NDP raise some serious concerns about the current direction of many of the proposed PCMH demonstration projects and point to some positive opportunities. We describe 6 early lessons from the NDP that address these concerns and then offer 4 recommendations for those assisting the transformation of primary care practices and 4 recommendations for individual practices attempting transformation.

BACKGROUND: The National Cardiogenic Shock Initiative is a single-arm, prospective, multicenter study to assess outcomes associated with early mechanical circulatory support (MCS) in patients presenting with acute myocardial infarction and cardiogenic shock (AMICS) treated with percutaneous coronary intervention (PCI). METHODS: Between July 2016 and February 2019, 35 sites participated and enrolled into the study. All centers agreed to treat patients with AMICS using a standard protocol emphasizing invasive hemodynamic monitoring and rapid initiation of MCS. Inclusion and exclusion criteria mimicked those of the "SHOCK" trial with an additional exclusion criteria of intra-aortic balloon pump counter-pulsation prior to MCS. RESULTS: A total of 171 consecutive patients were enrolled. Patients had an average age of 63 years, 77% were male, and 68% were admitted with AMICS. About 83% of patients were on vasopressors or inotropes, 20% had a witnessed out of hospital cardiac arrest, 29% had in-hospital cardiac arrest, and 10% were under active cardiopulmonary resuscitation during MCS implantation. In accordance with the protocol, 74% of patients had MCS implanted prior to PCI. Right heart catheterization was performed in 92%. About 78% of patients presented with ST-elevation myocardial infarction with average door to support times of 85 ± 63 min and door to balloon times of 87 ± 58 min. Survival to discharge was 72%. Creatinine ≥2, lactate >4, cardiac power output (CPO) <0.6 W, and age ≥ 70 years were predictors of mortality. Lactate and CPO measurements at 12-24 hr reliably predicted overall mortality postindex procedure. CONCLUSION: In contemporary practice, use of a shock protocol emphasizing best practices is associated with improved outcomes.

OBJECTIVE: To review the success rate of embolization in stopping hemorrhage for unstable patients with severe pelvic fractures, to calculate the time to achieve embolization, and to determine the yield from angiography. DESIGN: Retrospective review of patients admitted to a Level I trauma center with pelvic fractures during a 5-year period. MATERIALS AND METHODS: Charts were reviewed for Injury Severity Score, age, blood pressure, prothrombin time/partial thromboplastin time, pelvic fracture type, mortality, time to reach the angiography suite, time to achieve embolization, and mechanism of injury. MEASUREMENTS AND MAIN RESULTS: Of 806 patients admitted with pelvic fractures, 35 underwent pelvic angiography, and 15 (1.9%) required embolization. Embolization was successful for all patients. No deaths resulted from ongoing hemorrhage. Angiography yield in initially unstable patients was 64%. The mean age and initial hemodynamic instability were significantly greater in nonsurvivors. The time from arrival in the trauma bay to arrival in the angiography suite ranged from 50 to 1,140 minutes, and the time spent in the angiography suite performing embolization ranged from 50 to 140 minutes, with an average time of 90 minutes. Patients who were embolized within 3 hours of arrival had a significantly greater survival rate. CONCLUSION: Only a small percentage of patients with pelvic fractures require embolization, but when it is used, embolization can be 100% effective. Age, time to achieve embolization, and initial hemodynamic instability appear to be important factors in survival.

BACKGROUND: Focused assessment with sonography for trauma (FAST) as a screening tool in the evaluation of blunt abdominal trauma will lead to underdiagnosis of abdominal injuries and may have an impact on treatment and outcome in trauma patients. METHODS: From October 2001 to June 2002, a protocol for evaluating hemodynamically stable trauma patients with suspected blunt abdominal injury (BAI) admitted to our institution was implemented using FAST examination as a screening tool for BAI and computed tomographic (CT) scanning of the abdomen and pelvis as a confirmatory test. At the completion of the secondary survey, patients underwent a four-view FAST examination (Sonosite, Bothell, WA) followed within 1 hour by an abdominal/pelvic CT scan. The FAST examination was considered positive if it demonstrated evidence of free intra-abdominal fluid. Clinical, laboratory, and imaging results were recorded at admission, and FAST examination results were compared with CT scan findings, noting the discordance. RESULTS: Patients with suspicion for BAI were evaluated according to protocol (n = 372). Thirteen cases were excluded for inadequate FAST examinations, leaving 359 patients for analysis. There were 313 true-negative FAST examinations, 16 true-positives, 22 false-negatives, and 8 false-positives. Using CT scanning as the confirmatory test for hemoperitoneum, FAST examination had a sensitivity of 42%, a specificity of 98%, a positive predictive value of 67%, a negative predictive value of 93%, and an accuracy of 92%; chi analysis showed significant discordance between FAST examination and CT scan (5.85%, < 0.001). Six patients with false-negative FAST examinations required laparotomy for intra-abdominal injuries; 16 patients required admission for nonoperative management of injury. Of the 313 true-negative FAST examinations, 19 patients were noted to have intra-abdominal injuries without hemoperitoneum and 11 patients were noted to have retroperitoneal injuries. CONCLUSION: Use of FAST examination as a screening tool for BAI in the hemodynamically stable trauma patient results in underdiagnosis of intra-abdominal injury. This may have an impact on treatment and outcome in trauma patients. Hemodynamically stable patients with suspected BAI should undergo routine CT scanning.

AIMS: Myocarditis is a potentially fatal complication of immune checkpoint inhibitors (ICI). Sparse data exist on the use of cardiovascular magnetic resonance (CMR) in ICI-associated myocarditis. In this study, the CMR characteristics and the association between CMR features and cardiovascular events among patients with ICI-associated myocarditis are presented. METHODS AND RESULTS: From an international registry of patients with ICI-associated myocarditis, clinical, CMR, and histopathological findings were collected. Major adverse cardiovascular events (MACE) were a composite of cardiovascular death, cardiogenic shock, cardiac arrest, and complete heart block. In 103 patients diagnosed with ICI-associated myocarditis who had a CMR, the mean left ventricular ejection fraction (LVEF) was 50%, and 61% of patients had an LVEF ≥50%. Late gadolinium enhancement (LGE) was present in 48% overall, 55% of the reduced EF, and 43% of the preserved EF cohort. Elevated T2-weighted short tau inversion recovery (STIR) was present in 28% overall, 30% of the reduced EF, and 26% of the preserved EF cohort. The presence of LGE increased from 21.6%, when CMR was performed within 4 days of admission to 72.0% when CMR was performed on Day 4 of admission or later. Fifty-six patients had cardiac pathology. Late gadolinium enhancement was present in 35% of patients with pathological fibrosis and elevated T2-weighted STIR signal was present in 26% with a lymphocytic infiltration. Forty-one patients (40%) had MACE over a follow-up time of 5 months. The presence of LGE, LGE pattern, or elevated T2-weighted STIR were not associated with MACE. CONCLUSION: These data suggest caution in reliance on LGE or a qualitative T2-STIR-only approach for the exclusion of ICI-associated myocarditis.

A total of 1355 patients underwent internal sphincterotomy for chronic fissure in ano between 1980 and 1985. Surgical data were obtained for 1102 patients, and 829 patients responded to a questionnaire. Of the 1057 for whom the time of healing was recorded, 1033 (97.7 per cent) healed by a mean time of 5.6 weeks. No significant differences in satisfaction with the outcome or in deficits in continence were noted between groups undergoing lateral, bilateral or posterior midline sphincterotomy. Excision of the fissure was found to be unnecessary. According to responses on the questionnaires, deficits in continence ranging from 'sometimes' to 'frequently' included lack of control of flatus (35.1 per cent), soiling of underclothing (22.0 per cent) and accidental bowel movements (5.3 per cent). A significantly higher proportion of patients who had accidental bowel movements were aged over 40 years.

BACKGROUND: The content and context of family practice outpatient visits have never been fully described, leaving many aspects of family practice in a "black box," unseen by policymakers and understood only in isolation. This article describes community family practices, physicians, patients, and outpatient visits. METHODS: Practicing family physicians in northeast Ohio were invited to participate in a multimethod study of the content of primary care practice. Research nurses directly observed consecutive patient visits, and collected additional data using medical record reviews, patient and physician questionnaires, billing data, practice environment checklists, and ethnographic fieldnotes. RESULTS: Visits by 4454 patients seeing 138 physicians in 84 practices were observed. Outpatient visits to family physicians encompassed a wide variety of patients, problems, and levels of complexity. The average patient paid 4.3 visits to the practice within the past year. The mean visit duration was 10 minutes. Fifty-eight percent of visits were for acute illness, 24% for chronic illness, and 12% for well care. The most common uses of time were history-taking, planning treatment, physical examination, health education, feedback, family information, chatting, structuring the interaction, and patient questions. CONCLUSIONS: Family practice and patient visits are complex, with competing demands and opportunities to address a wide range of problems of individuals and families over time and at various stages of health and illness. Multimethod research in practice settings can identify ways to enhance the competing opportunities of family practice to improve the health of their patients.

OBJECTIVE: To describe models used in successful clinical initiatives to improve the quality of palliative care in critical care settings. DATA SOURCES: We searched the MEDLINE database from inception to April 2010 for all English language articles using the terms "intensive care," "critical care," or "ICU" and "palliative care"; we also hand-searched reference lists and author files. Based on review and synthesis of these data and the experiences of our interdisciplinary expert Advisory Board, we prepared this consensus report. DATA EXTRACTION AND SYNTHESIS: We critically reviewed the existing data with a focus on models that have been used to structure clinical initiatives to enhance palliative care for critically ill patients in intensive care units and their families. CONCLUSIONS: There are two main models for intensive care unit-palliative care integration: 1) the "consultative model," which focuses on increasing the involvement and effectiveness of palliative care consultants in the care of intensive care unit patients and their families, particularly those patients identified as at highest risk for poor outcomes; and 2) the "integrative model," which seeks to embed palliative care principles and interventions into daily practice by the intensive care unit team for all patients and families facing critical illness. These models are not mutually exclusive but rather represent the ends of a spectrum of approaches. Choosing an overall approach from among these models should be one of the earliest steps in planning an intensive care unit-palliative care initiative. This process entails a careful and realistic assessment of available resources, attitudes of key stakeholders, structural aspects of intensive care unit care, and patterns of local practice in the intensive care unit and hospital. A well-structured intensive care unit-palliative care initiative can provide important benefits for patients, families, and providers.

CONTEXT: As the availability of and demand for genetic testing for hereditary cancers increases in primary care and other clinical settings, alternative or adjunct educational methods to traditional genetic counseling will be needed. OBJECTIVE: To compare the effectiveness of a computer-based decision aid with standard genetic counseling for educating women about BRCA1 and BRCA2 genetic testing. DESIGN: Randomized controlled trial conducted from May 2000 to September 2002. SETTING AND PARTICIPANTS: Outpatient clinics offering cancer genetic counseling at 6 US medical centers enrolled 211 women with personal or family histories of breast cancer. INTERVENTIONS: Standard one-on-one genetic counseling (n = 105) or education by a computer program followed by genetic counseling (n = 106). MAIN OUTCOME MEASURES: Participants' knowledge, risk perception, intention to undergo genetic testing, decisional conflict, satisfaction with decision, anxiety, and satisfaction with the intervention. Counselor group measures were administered at baseline and after counseling. Computer group measures were administered at baseline, after computer use, and after counseling. Testing decisions were assessed at 1 and 6 months. Outcomes were analyzed by high vs low risk of carrying a BRCA1 or BRCA2 mutation. RESULTS: Both groups had comparable demographics, prior computer experience, medical literacy, and baseline knowledge of breast cancer and genetic testing, and both counseling and computer use were rated highly. Knowledge scores increased in both groups (P<.001) regardless of risk status, and change in knowledge was greater in the computer group compared with the counselor group (P =.03) among women at low risk of carrying a mutation. Perception of absolute risk of breast cancer decreased significantly after either intervention among all participants. Intention to undergo testing decreased significantly after either intervention among low-risk but not high-risk women. The counselor group had lower mean scores on a decisional conflict scale (P =.04) and, in low-risk women, higher mean scores on a satisfaction-with-decision scale (P =.001). Mean state anxiety scores were reduced by counseling but were within normal ranges for both groups at baseline and after either intervention, regardless of risk status. CONCLUSIONS: An interactive computer program was more effective than standard genetic counseling for increasing knowledge of breast cancer and genetic testing among women at low risk of carrying a BRCA1 or BRCA2 mutation. However, genetic counseling was more effective than the computer at reducing women's anxiety and facilitating more accurate risk perceptions. These results suggest that this computer program has the potential to stand alone as an educational intervention for low-risk women but should be used as a supplement to genetic counseling for those at high risk.

The impact of social and economic determinants of health status and the existence of racial and ethnic health care access disparities have been well-documented. This paper describes a model, the Health Care Access Barriers Model (HCAB), which provides a taxonomy and practical framework for the classification, analysis and reporting of those modifiable health care access barriers that are associated with health care disparities. The model describes three categories of modifiable health care access barriers: financial, structural, and cognitive. The three types of barriers are reciprocally reinforcing and affect health care access individually or in concert. These barriers are associated with screening, late presentation to care, and lack of treatment, which in turn result in poor health outcomes and health disparities. By targeting those barriers that are measurable and modifiable the model facilitates root-cause analysis and intervention design.

This article is the second in a series reporting on research exploring the effects of Mindfulness-based Stress Reduction on nurses and describes the quantitative data. The third article describes qualitative data. Treatment group participants reduced scores on 2 of 3 subscales of the Maslach Burnout Inventory significantly more than wait-list controls; within-group comparisons for both groups pretreatment and posttreatment revealed similar findings. Changes were maintained as long as 3-month posttreatment. Implications of these findings are discussed.

Introduction: myocarditis is a potentially fatal complication of immune checkpoint inhibitors (ICI). While corticosteroids are the cornerstones of the treatment, there are no data to guide the dose and timing.\n\nMethods: from an international registry of patients with ICI myocarditis diagnosed between 2013 and 2019, data on the type, dose (in methylprednisolone equivalent dose) and timing of steroids were extracted. Major cardiovascular events (MACE) were a composite of cardiovascular death, cardiogenic shock, cardiac arrest, and hemodynamically-significant complete heart block.\n\nResults: in total, 143 ICI myocarditis patients (67±13 years old, 29% women) were included. Among them, 125 received corticosteroids (87%), with the initial agent being either methylprednisolone (95, 76%), prednisone (25, 20%), hydrocortisone (2, 1.6%) or dexamethasone (3, 2.4%). The rates of overall MACE (by admission time tertile 1: 45.8%, tertile 2: 43.8%, tertile 3: 38.3%, P=0.746) and individual elements of MACE were unchanged from 2013 to 2019. The initial corticosteroid dose was categorized as low (&amp;lt;60mg), intermediate (≥60mg and ≤500mg) and high (&amp;gt;500mg). There was an inverse relationship between the occurrence of MACE and initial dose of corticosteroid, where MACE declined with increasing doses (low 61.9%, intermediate 54.6%, high 20.4%, P&amp;lt;0.001). The median time from admission to the first corticosteroids was 45 (15.5, 89) hours. Patients receiving corticosteroids within 24 hours had significantly lower MACE (7.0%) compared to those between 24-72 hours (34.3%) and those &amp;gt;72 hours (85.7%, P&amp;lt;0.001). The dose interacted with timing of initiation whereby high dose corticosteroids within 24 hours achieved the best outcome and low corticosteroids after 72 hours had the worst outcome (Fig 1).\n\nConclusions: ICI myocarditis is associated with high rate of MACE. Higher initial dose and earlier initiation of corticosteroids were associated with improved outcomes.

BACKGROUND: Human polymerized hemoglobin (PolyHeme, Northfield Laboratories) is a universally compatible oxygen carrier developed to treat life-threatening anemia. This multicenter phase III trial was the first US study to assess survival of patients resuscitated with a hemoglobin-based oxygen carrier starting at the scene of injury. STUDY DESIGN: Injured patients with a systolic blood pressure</=90 mmHg were randomized to receive field resuscitation with PolyHeme or crystalloid. Study patients continued to receive up to 6 U of PolyHeme during the first 12 hours postinjury before receiving blood. Control patients received blood on arrival in the trauma center. This trial was conducted as a dual superiority/noninferiority primary end point. RESULTS: Seven hundred fourteen patients were enrolled at 29 urban Level I trauma centers (79% men; mean age 37.1 years). Injury mechanism was blunt trauma in 48%, and median transport time was 26 minutes. There was no significant difference between day 30 mortality in the as-randomized (13.4% PolyHeme versus 9.6% control) or per-protocol (11.1% PolyHeme versus 9.3% control) cohorts. Allogeneic blood use was lower in the PolyHeme group (68% versus 50% in the first 12 hours). The incidence of multiple organ failure was similar (7.4% PolyHeme versus 5.5% control). Adverse events (93% versus 88%; p=0.04) and serious adverse events (40% versus 35%; p=0.12), as anticipated, were frequent in the PolyHeme and control groups, respectively. Although myocardial infarction was reported by the investigators more frequently in the PolyHeme group (3% PolyHeme versus 1% control), a blinded committee of experts reviewed records of all enrolled patients and found no discernable difference between groups. CONCLUSIONS: Patients resuscitated with PolyHeme, without stored blood for up to 6 U in 12 hours postinjury, had outcomes comparable with those for the standard of care. Although there were more adverse events in the PolyHeme group, the benefit-to-risk ratio of PolyHeme is favorable when blood is needed but not available.

Patellofemoral problems are a common cause of morbidity and reoperation after total knee arthroplasty. We made a prospective study of 52 patients who had bilateral arthroplasty (104 knees) and in whom the patella was resurfaced on one side and not on the other. A movable-bearing prosthesis with an anatomical femoral groove was implanted on both sides by the same surgeon using an otherwise identical technique. The mean follow-up was 5.24 years (2 to 10). In the 30 available patients (60 knees) there was no difference between the two sides in subjective preference, performance on ascending and descending stairs or the incidence of anterior knee pain. Radiographs showed no differences in prosthetic alignment, femoral condylar height, patellar congruency or joint line position. The use of an appropriate prosthetic design and careful surgical technique can provide equivalent results after knee arthroplasty with or without patellar resurfacing. Given the indications and criteria, which we discuss, retention of the patellar surface is an acceptable option.

BACKGROUND: Clostridium difficile colitis has increased in incidence and severity, and treatment failure with metronidazole therapy has increasingly been documented. It is uncertain whether treatment with vancomycin is more effective than treatment with metronidazole, but concern over the emergence of vancomycin resistance has motivated the search for alternative therapy. Nitazoxanide, a nitrothiazolide, blocks anaerobic metabolism of eukaryocyes and effectively treats intestinal infestation due to Cryptosporidium or Giardia species. At low concentrations, this compound inhibits C. difficile in vitro. METHODS: We designed a prospective, randomized, double-blind study to compare nitazoxanide to metronidazole in treating hospitalized patients with C. difficile colitis. RESULTS: Thirty-four patients received metronidazole at a dosage of 250 mg 4 times per day for 10 days, 40 patients received nitazoxanide at a dosage of 500 mg 2 times per day for 7 days, and 36 patients received nitazoxanide at a dosage of 500 mg 2 times per day for 10 days. After 7 days of treatment, 28 (82.4%) of 34 patients had responded to metronidazole therapy, compared with 68 (89.5%) of 76 who had received nitazoxanide therapy (difference, 7.1%; 95% confidence interval, -7.1% to 25.5%). Thirty-one days after beginning treatment, sustained responses were observed in 19 (57.6%) of 33 patients who had received metronidazole therapy for 10 days, compared with 25 (65.8%) of 38 who had received nitazoxanide for 7 days and 26 (74.3%) of 35 who had received nitazoxanide for 10 days (P = .34). CONCLUSION: Nitazoxanide is at least as effective as metronidazole in treating C. difficile colitis.

Sixty 12-week-old infants participated in a laboratory study to explore the relations between temperament and cardiac vagal tone. Temperament was evaluated via laboratory observations and maternal ratings. Cardiac vagal tone, measured as the amplitude of respiratory sinus arrhythmia, was quantified from beat-to-beat heart period data collected during a resting baseline period and during the laboratory assessment of temperament. Specific hypotheses were investigated relating temperament to both basal cardiac vagal tone and changes in cardiac vagal tone during social/attention challenges. Infants with higher baseline cardiac vagal tone were rated in the laboratory as showing fewer negative behaviors and were less disrupted by the experimental procedure. Infants who decreased cardiac vagal tone during the laboratory assessment were rated on maternal report temperament scales as having longer attention spans, and being more easily soothed.

BACKGROUND: Understanding the organization of primary care practices is essential for implementing changes related to delivery of preventive or other health care services. A theoretical model derived from complexity theory provides a framework for understanding practice change. METHODS: Data were reviewed from brief participant observation fieldnotes collected in the 84 practices of the Direct Observation of Primary Care (DOPC) study and in 27 practices from three similar studies investigating preventive services delivery. These data were synthesized with information from an extensive search of the social science, nursing, and health services literature concerning practice organization, and of the literature on complexity theory from the fields of mathematics, physics, biology, management, medicine, and family systems, to create a complexity model of primary care practice. RESULTS: Primary care practices are understood as complex adaptive systems consisting of agents, such as patients, office staff, and physicians, who enact internal models of income generation, patient care, and organizational operations. These internal models interact dynamically to create each unique practice. The particular shape of each practice is determined by its primary goals. The model suggests three strategies for promoting change in practice and practitioner behavior: joining, transforming, and learning. CONCLUSIONS: This model has important implications for understanding change in primary care practice. Practices are much more complex than present strategies for change assume. The complexity model identified why some strategies work in particular practices and others do not.

Objective: To delineate blood transfusion practices and outcomes in patients with major burn injury. Context: Patients with major burn injury frequently require multiple blood transfusions; however, the effect of blood transfusion after major burn injury has had limited study. Design: Multicenter retrospective cohort analysis. Setting: Regional burn centers throughout the United States and Canada. Patient Population: Patients admitted to a participating burn center from January 1 through December 31, 2002, with acute burn injuries of ≥20% total body surface area. Outcomes Measured: Outcome measurements included mortality, number of infections, length of stay, units of blood transfused in and out of the operating room, number of operations, and anticoagulant use. Results: A total of 21 burn centers contributed data on 666 patients; 79% of patients survived and received a mean of 14 units of packed red blood cells during their hospitalization. Mortality was related to patient age, total body surface area burn, inhalation injury, number of units of blood transfused outside the operating room, and total number of transfusions. The number of infections per patient increased with each unit of blood transfused (odds ratio, 1.13; p < .001). Patients on anticoagulation during hospitalization received more blood than patients not on anticoagulation (16.3 ± 1.5 vs. 12.3 ± 1.5, p < .001). Conclusions: The number of transfusions received was associated with mortality and infectious episodes in patients with major burns even after factoring for indices of burn severity. The utilization of blood products in the treatment of major burn injury should be reserved for patients with a demonstrated physiologic need.

OBJECTIVE: To review the use of screening criteria (also known as "triggers") as a mechanism for engaging palliative care consultants to assist with care of critically ill patients and their families in the ICU. DATA SOURCES: We searched the MEDLINE database from inception to December 2012 for all English-language articles using the terms "trigger," "screen," "referral," "tool," "triage," "case-finding," "assessment," "checklist," "proactive," or "consultation," together with "intensive care" or "critical care" and "palliative care," "supportive care," "end-of-life care," or "ethics." We also hand-searched reference lists and author files and relevant tools on the Center to Advance Palliative Care website. STUDY SELECTION: Two members (a physician and a nurse with expertise in clinical research, intensive care, and palliative care) of the interdisciplinary Improving Palliative Care in the ICU Project Advisory Board presented studies and tools to the full Board, which made final selections by consensus. DATA EXTRACTION: We critically reviewed the existing data and tools to identify screening criteria for palliative care consultation, to describe methods for selecting, implementing, and evaluating such criteria, and to consider alternative strategies for increasing access of ICU patients and families to high-quality palliative care. DATA SYNTHESIS: The Improving Palliative Care in the ICU Advisory Board used data and experience to address key questions relating to: existing screening criteria; optimal methods for selection, implementation, and evaluation of such criteria; and appropriateness of the screening approach for a particular ICU. CONCLUSIONS: Use of specific criteria to prompt proactive referral for palliative care consultation seems to help reduce utilization of ICU resources without changing mortality, while increasing involvement of palliative care specialists for critically ill patients and families in need. Existing data and resources can be used in developing such criteria, which should be tailored for a specific ICU, implemented through an organized process involving key stakeholders, and evaluated by appropriate measures. In some settings, other strategies for increasing access to palliative care may be more appropriate.
