RESUMO
OBJECTIVES: To identify circumstances in which repeated measures of organ failure would improve mortality prediction in ICU patients. DESIGN: Retrospective cohort study, with external validation in a deidentified ICU database. SETTING: Eleven ICUs in three university hospitals within an academic healthcare system in 2014. PATIENTS: Adults (18 yr old or older) who satisfied the following criteria: 1) two of four systemic inflammatory response syndrome criteria plus an ordered blood culture, all within 24 hours of hospital admission; and 2) ICU admission for at least 2 calendar days, within 72 hours of emergency department presentation. INTERVENTION: NoneMEASUREMENTS AND MAIN RESULTS:: Data were collected until death, ICU discharge, or the seventh ICU day, whichever came first. The highest Sequential Organ Failure Assessment score from the ICU admission day (ICU day 1) was included in a multivariable model controlling for other covariates. The worst Sequential Organ Failure Assessment scores from the first 7 days after ICU admission were incrementally added and retained if they obtained statistical significance (p < 0.05). The cohort was divided into seven subcohorts to facilitate statistical comparison using the integrated discriminatory index. Of the 1,290 derivation cohort patients, 83 patients (6.4%) died in the ICU, compared with 949 of the 8,441 patients (11.2%) in the validation cohort. Incremental addition of Sequential Organ Failure Assessment data up to ICU day 5 improved the integrated discriminatory index in the validation cohort. Adding ICU day 6 or 7 Sequential Organ Failure Assessment data did not further improve model performance. CONCLUSIONS: Serial organ failure data improve prediction of ICU mortality, but a point exists after which further data no longer improve ICU mortality prediction of early sepsis.

BACKGROUND: It is standard practice to administer prophylactic antibiotics post lung transplantation. However, no studies have evaluated the impact of culture positivity. The purpose of this study was to evaluate early post-transplant outcomes of culture-positive and culture-negative lung transplant (LT) recipients and the appropriateness of the empiric regimens used. METHODS: Adult patients who received an LT at Emory University Hospital between January 1, 2010 and August 31, 2015 were reviewed and stratified into three groups: (i) culture-positive appropriate empiric treatment, (ii) culture-positive inappropriate empiric treatment, and (iii) culture-negative. Antibiotics were defined as appropriate if bacteria were sensitive to the empiric regimen. The primary endpoint was 30-day mortality. Secondary endpoints included hospital length of stay (LOS), intensive care unit (ICU) LOS, percent neutrophil count in a bronchoalveolar lavage (BAL) sample, presence of airway ischemia, and appropriateness of the empiric antibiotic regimen. RESULTS: Nine, zero, and four patients died within 30 days in the culture-positive appropriate (n = 113), culture-positive inappropriate (n = 5), and culture-negative groups (n = 29) (P = .564) respectively. The median hospital LOS was 19, 16, and 15 days respectively. Median ICU LOS was 6, 5, and 7 respectively. The respective percent neutrophil counts in the BAL fluid were 79, 83, and 65. The presence of airway ischemia was only documented in eight patients, all in the culture-positive appropriate group. CONCLUSION: We did not identify an association between antibiotic appropriateness and 30-day mortality, hospital LOS, or ICU LOS in post-LT recipients.

OBJECTIVES: Literature generally finds no advantages in mortality risk for albumin over cheaper alternatives in many settings. Few studies have combined financial and nonfinancial strategies to reduce albumin overuse. We evaluated the effect of a sequential multifaceted intervention on decreasing albumin use in ICU and explore the effects of different strategies. DESIGN: Prospective prepost cohort study. SETTING: Eight ICUs at two hospitals in an academic healthcare system. PATIENTS: Adult patients admitted to study ICUs from September 2011 to August 2014 (n = 22,004). INTERVENTIONS: Over 2 years, providers in study ICUs participated in an intervention to reduce albumin use involving monthly feedback and explicit financial incentives in the first year and internal guidelines and order process changes in the second year. MEASUREMENTS AND MAIN RESULTS: Outcomes measured were albumin orders per ICU admission, direct albumin costs, and mortality. Mean (SD) utilization decreased 37% from 2.7 orders (6.8) per admission during the baseline to 1.7 orders (4.6) during the intervention (p < 0.001). Regression analysis revealed that the intervention was independently associated with 0.9 fewer orders per admission, a 42% relative decrease. This adjusted effect consisted of an 18% reduction in the probability of using any albumin (p < 0.001) and a 29% reduction in the number of orders per admission among patients receiving any (p < 0.001). Secondary analysis revealed that probability reductions were concurrent with internal guidelines and order process modification while reductions in quantity occurred largely during the financial incentives and feedback period. Estimated cost savings totaled $2.5M during the 2-year intervention. There was no significant difference in ICU or hospital mortality between baseline and intervention. CONCLUSIONS: A sequential intervention achieved significant reductions in ICU albumin use and cost savings without changes in patient outcomes, supporting the combination of financial and nonfinancial strategies to align providers with evidence-based practices.

OBJECTIVES: Healthcare systems strive to provide quality care at lower cost. Arterial blood gas testing, chest radiographs, and RBC transfusions provide an important example of opportunities to reduce excess resource utilization within the ICU. We describe the effect of a multifaceted quality improvement program designed to decrease the avoidable arterial blood gases, chest radiographs, and RBC utilization on utilization of these resources and patient outcomes. DESIGN: Prospective pre-post cohort study. SETTING: Seven ICUs in an academic healthcare system. PATIENTS: All adult ICU patients admitted to study ICUs during consecutive baseline (n = 7,357), intervention (n = 7,553), and follow-up (n = 7,657) years between September 2010 and August 2013. INTERVENTIONS: A multifaceted quality improvement program including provider education, audit and feedback, and unit-based provider financial incentives targeting arterial blood gas, chest radiograph, and RBC utilization. MEASUREMENTS AND MAIN RESULTS: The primary outcome was the number of orders for arterial blood gases, chest radiographs, and RBCs per patient. Compared with the baseline period, unadjusted arterial blood gas, chest radiograph, and RBC utilization in the intervention period was reduced by 42%, 26%, and 17%, respectively (p < 0.01). After adjusting for potentially relevant patient factors, the intervention was associated with 128 fewer arterial blood gases, 73 fewer chest radiographs, and 16 fewer RBCs per 100 patients (p < 0.01). This effect was durable during the follow-up year. This reduction yielded an approximate net savings of $1.5 M in direct costs over the intervention and follow-up years after accounting for the direct costs of the program. Unadjusted hospital mortality decreased from 7% in the baseline period to 5.2% in the intervention period (p < 0.01). This reduction remained significant after adjusting for patient factors (odds ratio = 0.43; p < 0.01). CONCLUSIONS: Implementation of a multifaceted quality improvement program including financial incentives was associated with significant improvements in resource utilization. Our findings provide evidence supporting the safety, effectiveness, and sustainability of incentive-based quality improvement interventions.

PURPOSE OF REVIEW: Fluid therapy practices are an ongoing debate in critical care as evidence continues to emerge on the clinical effectiveness of different fluids and regimens. Although fluid therapy is a frequent and often costly treatment in the ICU, cost considerations have been largely absent from these studies. To facilitate a more structured approach to understanding fluid therapy costs and their role in clinical practice, we summarize currently available options and describe a framework for identifying and organizing relevant costs. RECENT FINDINGS: Fluid therapy is a complex area of care that has been rarely studied from a cost-effectiveness perspective. We identify seven cost areas that capture fluid therapy-related costs during preutilization, point-of-utilization, and postutilization periods. These costs are driven by decisions on the type of fluid and administration strategy. Although estimates for some cost areas could be informed by medical literature, other cost areas remain unclear and require further investigation. SUMMARY: Given the growing emphasis on the value of care, providers must recognize the important cost consequences of clinical decisions in fluid therapy. Future research into fluid therapy costs is needed and can be guided by this framework. Developing a complete cost picture is an initial and necessary step for improving values for patients, hospitals, and healthcare systems.

In 2017 the Medicare Shared Savings Program (MSSP) began incorporating regional spending into accountable care organization (ACO) benchmarks, thus favoring the participation of ACOs and practices with lower baseline spending than their region. To characterize providers' responses to these incentives, we isolated changes in spending due to changes in the mix of ACOs and practices participating in the MSSP. In contrast to earlier participation patterns, the composition of the MSSP after 2017 increasingly shifted to providers with lower preexisting levels of spending relative to their region, consistent with a selection response. Changes occurred through the entry of new ACOs with lower baseline spending, the exit of higher-spending ACOs, and the reconfiguration of participant lists favoring lower-spending practices within continuing ACOs. These participation patterns varied meaningfully by ACO type. Although compositional changes could not be definitively tied to benchmarking changes, the disproportionate participation of providers with lower baseline spending implies substantial costs and the need for ACO benchmarking reforms.

Antitrust guidance specifies that participation in Medicare accountable care organizations (ACOs) is sufficient to meet clinical integration standards for separately owned providers to jointly negotiate with insurers. Accordingly, ACO participation may facilitate price increases through a less conventional, "softer" consolidation that would not be categorically challenged as price fixing. Using commercial claims and data on health system membership and ACO participation, we found some abrupt, large price increases for independent primary care practices that joined health system-led ACOs but were not acquired by systems. These price jumps were rare, however, increasing prices by just 4 percent, on average, among all independent practices in system-led ACOs. Additional analyses suggested minimal increases in health systems' primary care prices or market shares from ACO contracting. Thus, the price jumps were more consistent with an extension of existing pricing power from systems to some independent practices than with a major expansion of system market power. Nevertheless, the potential for growth of these arrangements through ACOs argues for closer monitoring and evaluation.

PURPOSE: Using administrative codes and minimal physiologic and laboratory data, we sought a high-specificity identification strategy for patients whose sepsis initially appeared during their ICU stay. MATERIALS AND METHODS: We studied all patients discharged from an academic hospital between September 1, 2013 and October 31, 2014. Administrative codes and minimal physiologic and laboratory criteria were used to identify patients at high risk of developing the onset of sepsis in the ICU. Two clinicians then independently reviewed the patient record to verify that the screened-in patients appeared to become septic during their ICU admission. RESULTS: Clinical chart review verified sepsis in 437/466 ICU stays (93.8%). Of these 437 encounters, only 151 (34.6%) were admitted to the ICU with neither SIRS nor evidence of infection and therefore appeared to become septic during their ICU stay. CONCLUSIONS: Selected administrative codes coupled to SIRS criteria and applied to patients admitted to ICU can yield up to 94% authentic sepsis patients. However, only 1/3 of patients thus identified appeared to become septic during their ICU stay. Studies that depend on high-intensity monitoring for description of the time course of sepsis require clinician review and verification that sepsis initially appeared during the monitoring period.

The balloon cell nevus is an uncommon variant of melanocytic nevi in which the majority of the proliferation consists of cells demonstrating peculiarly large clear, foamy, or finely vacuolated cytoplasm. The vacuolated cells represent altered nevus cells and upon immunoperoxidase evaluation react positively with several melanocytic markers. Complete excision results in cure. This report describes the second balloon cell nevus of the oral mucosa documented in the English-language literature.
