Application of Unit-Level Cost Transparency, Education, Enhanced Audit, and Feedback of Anonymized Peer Ranking to Promote Judicious Use of 25% Albumin in Critical Care Units.

Objective: Hyperoncotic 25% albumin is widely used for fluid resuscitation in intensive care units. However, this practice remains controversial. By 2012 in our intensive care unit, annual 25% albumin expenditures had steadily increased to exceed $1 million. This prompted efforts to promote more judicious use. Design: Prospective time series cohort analysis using statistical process control charts. Setting: Seventy-six-bed quaternary level cardiovascular surgical intensive care unit (CVICU), organized into 6 adjacent units. Patients: Adult cardiac, thoracic, and vascular surgery patients admitted postoperatively to the CVICU during the study period. Interventions: Over 12 months starting March 2013, we sequentially implemented unit-level 25% albumin cost transparency, provider education, and individualized audit and feedback of anonymized peer ranking of albumin prescriptions. Measurements and Main Results: C control charts were used for analysis of monthly unit-level direct albumin costs for 20 months. Balance measures including red cell transfusions, number of diagnoses of pleural effusions, and length of stay were also tracked. Monthly average albumin expenditures had decreased 61% by December 2014, and there was no evidence of adverse changes in any of the balance measures. These reductions have been sustained. Conclusion: Sequential implementation of multimodal strategies can alter clinician practices to achieve substantial unit-level reduction in 25% albumin utilization without harm to patients.

Telemedicine/Virtual ICU: Where Are We and Where Are We Going?

Intensive care unit telemedicine (tele-ICU) is technology enabled care delivered from off-site locations that was developed to address the increasing complexity of patients and insufficient supply of intensivists. Although tele-ICU deployment is increasing, it continues to cover only a small proportion of ICU patients. This is primarily due to expense, with first-year costs exceeding $50,000 per bed. Meta-analyses of outcomes indicate survival benefits and quality improvements, albeit with significant heterogeneity. Depending on the context, a wide range of estimated incremental cost-effectiveness ratios reflects variable effects on cost and outcomes, such as mortality or length of stay. Tele-ICUs may fit within a hybrid model of care to complement high-intensity ICU staff coverage. However, more research is required to foster consensus and determine best practices. This review summarizes data on tele-ICU structure, operations, outcomes, and costs. Evidence was extracted from meta-analyses, with secondary data from Cleveland Clinic's tele-ICU experience.

Correlation between PaO2/FiO2 and airway and vascular parameters in the assessment of cellular ex vivo lung perfusion system.

BACKGROUND: Ex vivo lung perfusion (EVLP) may be an essential process for the pre-transplant evaluation of the donor lungs. Currently, the partial pressure of oxygen/fraction of inspired oxygen (PaO2/FiO2, or PF) ratio is the standard in the assessment of lung function in cellular EVLP, whereas other parameters, including airway and vascular parameters, have only been partially utilized. The primary purpose of this study is to assess the potential utility of other parameters as a surrogate of lung function in EVLP. METHODS: Yorkshire swine lungs (n = 12) and rejected human donor lungs (n = 12) were perfused in cellular-based EVLP for 2 hours. PF ratio, airway parameters (peak airway pressure, plateau pressure, dynamic compliance and static compliance) and vascular parameters (pulmonary vascular resistance and pulmonary artery pressure) were measured. The correlations between PF ratio and one of these parameters were analyzed. RESULTS: Correlations were identified in the following combinations: PF ratio and airway parameters (p < 0.05, each); PF ratio and vascular parameters (p < 0.05, each); static compliance and pulmonary vascular resistance in swine lungs (p = 0.0001); and PF ratio and airway parameters in rejected human lungs (p < 0.05, each). There were significant differences in all parameters between suitable cases and non-suitable cases in swine lungs (p < 0.02, each). CONCLUSIONS: Our results show that airway parameters are complementary quantitative indicators of lung function in cellular EVLP, based on the correlations with PF ratio in both swine lungs and human lungs.

Economic trends from 2003 to 2010 for perioperative myocardial infarction: a retrospective, cohort study.

BACKGROUND: Perioperative myocardial infarction (PMI) is a major surgical complication that is costly and causes much morbidity and mortality. Diagnosis and treatment of PMIs have evolved over time. Many treatments are expensive but may reduce ancillary expenses including the duration of hospital stay. The time-dependent economic impact of novel treatments for PMI remains unexplored. The authors thus evaluated absolute and incremental costs of PMI over time and discharge patterns. METHODS: Approximately 31 million inpatient discharges were analyzed between 2003 and 2010 from the California State Inpatient Database. PMI was defined using International Classification of Diseases, Ninth Revision, Clinical Modification codes. Propensity matching generated 21,637 pairs of comparable patients. Quantile regression modeled incremental charges as the response variable and year of discharge as the main predictor. Time trends of incremental charges adjusted to 2012 dollars, mortality, and discharge destination was evaluated. RESULTS: Median incremental charges decreased annually by $1,940 (95% CI, $620 to $3,250); P < 0.001. Compared with non-PMI patients, the median length of stay of patients who experienced PMI decreased significantly over time: yearly decrease was 0.16 (0.10 to 0.23) days; P < 0.001. No mortality differences were seen; but over time, PMI patients were increasingly likely to be transferred to another facility. CONCLUSIONS: Reduced incremental cost and unchanged mortality may reflect improving efficiency in the standard management of PMI. An increasing fraction of discharges to skilled nursing facilities seems likely a result from hospitals striving to reduce readmissions. It remains unclear whether this trend represents a transfer of cost and risk or improves patient care.

Emergency medical services intervals and survival in trauma: assessment of the "golden hour" in a North American prospective cohort.

STUDY OBJECTIVE: The first hour after the onset of out-of-hospital traumatic injury is referred to as the "golden hour," yet the relationship between time and outcome remains unclear. We evaluate the association between emergency medical services (EMS) intervals and mortality among trauma patients with field-based physiologic abnormality. METHODS: This was a secondary analysis of an out-of-hospital, prospective cohort registry of adult (aged > or =15 years) trauma patients transported by 146 EMS agencies to 51 Level I and II trauma hospitals in 10 sites across North America from December 1, 2005, through March 31, 2007. Inclusion criteria were systolic blood pressure less than or equal to 90 mm Hg, respiratory rate less than 10 or greater than 29 breaths/min, Glasgow Coma Scale score less than or equal to 12, or advanced airway intervention. The outcome was in-hospital mortality. We evaluated EMS intervals (activation, response, on-scene, transport, and total time) with logistic regression and 2-step instrumental variable models, adjusted for field-based confounders. RESULTS: There were 3,656 trauma patients available for analysis, of whom 806 (22.0%) died. In multivariable analyses, there was no significant association between time and mortality for any EMS interval: activation (odds ratio [OR] 1.00; 95% confidence interval [CI] 0.95 to 1.05), response (OR 1.00; 95% CI 9.97 to 1.04), on-scene (OR 1.00; 95% CI 0.99 to 1.01), transport (OR 1.00; 95% CI 0.98 to 1.01), or total EMS time (OR 1.00; 95% CI 0.99 to 1.01). Subgroup and instrumental variable analyses did not qualitatively change these findings. CONCLUSION: In this North American sample, there was no association between EMS intervals and mortality among injured patients with physiologic abnormality in the field.
