RESUMO
OBJECTIVES: To provide an overview of key elements of the Affordable Care Act. To evaluate ways in which the Affordable Care Act will likely impact the practice of critical care medicine. To describe strategies that may help health systems and providers effectively adapt to changes brought about by the Affordable Care Act. DATA SOURCES AND SYNTHESIS: Data sources for this concise review include search results from the PubMed and Embase databases, as well as sources relevant to public policy such as the text of the Patient Protection and Affordable Care Act and reports of the Congressional Budget Office. As all of the Affordable Care Act's provisions will not be fully implemented until 2019, we also drew upon cost, population, and utilization projections, as well as the experience of existing state-based healthcare reforms. CONCLUSIONS: The Affordable Care Act represents the furthest reaching regulatory changes in the U.S. healthcare system since the 1965 Medicare and Medicaid provisions of the Social Security Act. The Affordable Care Act aims to expand health insurance coverage to millions of Americans and place an emphasis on quality and cost-effectiveness of care. From models which link pay and performance to those which center on episodic care, the Affordable Care Act outlines sweeping changes to health systems, reimbursement structures, and the delivery of critical care. Staffing models that include daily rounding by an intensivist, palliative care integration, and expansion of the role of telemedicine in areas where intensivists are inaccessible are potential strategies that may improve quality and profitability of ICU care in the post-Affordable Care Act era.

BACKGROUND: The context of the study is the Agency for Healthcare Research and Quality's Hospital Survey on Patient Safety Culture (HSOPSC). The purpose of the study is to analyze how different elements of patient safety culture are associated with clinical handoffs and perceptions of patient safety. METHODS: The study was performed with hierarchical multiple linear regression on data from the 2010 Survey. We examine the statistical relationships between perceptions of handoffs and transitions practices, patient safety culture, and patient safety. We statistically controlled for the systematic effects of hospital size, type, ownership, and staffing levels on perceptions of patient safety. RESULTS: The main findings were that the effective handoff of information, responsibility, and accountability were necessary to positive perceptions of patient safety. Feedback and communication about errors were positively related to the transfer of patient information; teamwork within units and the frequency of events reported were positively related to the transfer of personal responsibility during shift changes; and teamwork across units was positively related to the unit transfers of accountability for patients. CONCLUSIONS: In summary, staff views on the behavioral dimensions of handoffs influenced their perceptions of the hospital's level of patient safety. Given the known psychological links between perception, attitude, and behavior, a potential implication is that better patient safety can be achieved by a tight focus on improving handoffs through training and monitoring.

The severity of patient illnesses and medication complexity in post-operative critically ill patients increase the risk for a prolonged QT interval. We determined the prevalence of prolonged QTc in surgical intensive care unit (SICU) patients. We performed a prospective cross-sectional study over a 15-month period at a major academic center. SICU pre-admission and admission EKGs, patient demographics, and laboratory values were analyzed. QTc was evaluated as both a continuous and dichotomous outcome (prolonged QTc > 440 ms). 281 patients were included in the study: 92 % (n = 257) post-operative and 8 % (n = 24) non-operative. On pre-admission EKGs, 32 % of the post-operative group and 42 % of the non-operative group had prolonged QTc (p = 0.25); on post-admission EKGs, 67 % of the post-operative group but only 33 % of the non-operative group had prolonged QTc (p < 0.01). The average change in QTc in the post-operative group was +30.7 ms, as compared to +2 ms in the non-operative group (p < 0.01). On multivariable adjustment for long QTc as a dichotomous outcome, pre-admission prolonged QTc (OR 3.93, CI 1.93-8.00) and having had an operative procedure (OR 4.04, CI 1.67-9.83) were associated with developing prolonged QTc. For QTc as a continuous outcome, intra-operative beta-blocker use was associated with a statistically-significant decrease in QTc duration. None of the patients developed a lethal arrhythmia in the ICU. Prolonged QTc is common among post-operative SICU patients (67 %), however lethal arrhythmias are uncommon. The operative experience increases the risk for long QTc.

Background: At a tertiary referral and Level I trauma center, current institutional guidelines suggest initial aminoglycoside doses of gentamicin or tobramycin 4 mg/kg and amikacin 16 mg/kg for patients admitted to surgical intensive care units (SICUs) with suspected gram-negative infection. The objective of this study was to evaluate initial aminoglycoside dosing and peak serum drug concentrations in critically ill surgery patients to characterize the aminoglycoside volume of distribution (Vd) and determine an optimal standardized dosing strategy. Methods: This retrospective, observational, single-center study included adult SICU patients who received an aminoglycoside for additional gram-negative coverage. Descriptive statistics were used to evaluate the patient population, aminoglycoside dosing, and Vd. Multivariable linear regression was applied to determine variables associated with greater aminoglycoside Vd. The mortality rate was compared in patients who achieved adequate initial peak concentrations versus those who did not. Results: One hundred seventeen patients received an aminoglycoside in the SICUs, of whom 58 had an appropriately timed peak concentration measurement. The mean Acute Physiology, Age, and Chronic Health Evaluation (APACHE) II score was 27.8 ± 8.9. The Vd in patients receiving gentamicin, tobramycin, and amikacin was 0.49 ± 0.10, 0.41 ± 0.09, and 0.53 ± 0.13 L/kg, respectively. Together, the mean aminoglycoside Vd was 0.50 ± 0.12 L/kg. Gentamicin or tobramycin 5 mg/kg achieved goal peak concentrations in 24 patients (63.2%), and amikacin 20 mg/kg achieved the desired concentrations in nine patients (50.0%). Net fluid status, Body Mass Index, and vasopressor use were not predictive of Vd. There was no difference in the in-hospital mortality rate in patients who achieved adequate peak concentrations versus those who did not (26.8% versus 26.7%; p = 0.99). Conclusion: High aminoglycoside doses are needed in critically ill surgery patients to achieve adequate initial peak concentrations because of the high Vd. Goal peak concentrations were optimized at doses of gentamicin or tobramycin 5 mg/kg, and amikacin 20 mg/kg.

PURPOSE: To appraise the reported validity and reliability of evaluation methods used in high-quality trials of continuing medical education (CME). METHOD: The authors conducted a systematic review (1981 to February 2006) by hand-searching key journals and searching electronic databases. Eligible articles studied CME effectiveness using randomized controlled trials or historic/concurrent comparison designs, were conducted in the United States or Canada, were written in English, and involved at least 15 physicians. Sequential double review was conducted for data abstraction, using a traditional approach to validity and reliability. RESULTS: Of 136 eligible articles, 47 (34.6%) reported the validity or reliability of at least one evaluation method, for a total of 62 methods; 31 methods were drawn from previous sources. The most common targeted outcome was practice behavior (21 methods). Validity was reported for 31 evaluation methods, including content (16), concurrent criterion (8), predictive criterion (1), and construct (5) validity. Reliability was reported for 44 evaluation methods, including internal consistency (20), interrater (16), intrarater (2), equivalence (4), and test-retest (5) reliability. When reported, statistical tests yielded modest evidence of validity and reliability. Translated to the contemporary classification approach, our data indicate that reporting about internal structure validity exceeded reporting about other categories of validity evidence. CONCLUSIONS: The evidence for CME effectiveness is limited by weaknesses in the reported validity and reliability of evaluation methods. Educators should devote more attention to the development and reporting of high-quality CME evaluation methods and to emerging guidelines for establishing the validity of CME evaluation methods.

OBJECTIVE: Few instruments are available to measure the performance of intensive care unit (ICU) clinical information systems. Our objectives were: 1) to develop a survey-based metric that assesses the automation and usability of an ICU's clinical information system; 2) to determine whether higher scores on this instrument correlate with improved outcomes in a multi-institution quality improvement collaborative. DESIGN: This is a cross-sectional study of the medical directors of 19 Michigan ICUs participating in a state-wide quality improvement collaborative designed to reduce the rate of catheter-related blood stream infections (CRBSI). Respondents completed a survey assessing their ICU's information systems. MEASUREMENTS: The mean of 54 summed items on this instrument yields the clinical information technology (CIT) index, a global measure of the ICU's information system performance on a 100 point scale. The dependent variable in this study was the rate of CRBSI after the implementation of several evidence-based recommendations. A multivariable linear regression analysis was used to examine the relationship between the CIT score and the post-intervention CRBSI rates after adjustment for the pre-intervention rate. RESULTS: In this cross-sectional analysis, we found that a 10 point increase in the CIT score is associated with 4.6 fewer catheter related infections per 1,000 central line days for ICUs who participate in the quality improvement intervention for 1 year (95% CI: 1.0 to 8.0). CONCLUSIONS: This study presents a new instrument to examine ICU information system effectiveness. The results suggest that the presence of more sophisticated information systems was associated with greater reductions in the bloodstream infection rate.

HYPOTHESIS: Perioperative allogeneic blood product transfusion would be associated with venous thromboembolic complications in surgical patients. DESIGN: Observational study using a state discharge database. SETTING: Nonfederal acute care hospitals in Maryland performing colorectal cancer resections between January 1, 1994, and December 31, 2000. PATIENTS: We obtained data on 14 014 adult patients having a primary diagnosis code for colorectal cancer and a primary procedure code for colorectal resection. MAIN OUTCOME MEASURES: The primary outcome variable was a discharge diagnosis of venous thromboembolism (VTE). RESULTS: Venous thromboembolism occurred in 1% of patients and was associated with an adjusted 3.8-fold increase in mortality (odds ratio, 3.8; 95% confidence interval, 2.1-6.8), a 61% increase in mean hospital length of stay, and a 72% increase in mean total hospital charges. Risk factors for VTE after adjustment included transfusion, female sex, age 80 years or older, moderate to severe liver disease vs no liver disease, admission through the emergency department, and low annual surgeon case volume. Transfusion was associated with an increase in the odds of developing VTE in women (odds ratio, 1.8; 95% confidence interval, 1.2-2.6) but not in men (odds ratio, 0.9; 95% confidence interval, 0.5-1.9). In the absence of transfusion, female compared with male sex was not associated with an increased risk of VTE (odds ratio, 1.2; 95% confidence interval, 0.8-1.7). CONCLUSIONS: In this large observational study of patients undergoing colorectal cancer resection, perioperative allogeneic blood transfusion was associated with an increased risk of VTE in women but not in men. Given the substantial morbidity and mortality associated with VTE and the implication that this finding has for postoperative management in women, this association must be confirmed in independent studies.

PURPOSE: The aim of this study was to describe hospital efforts to meet the Leapfrog Group's intensive care unit (ICU) physician staffing (IPS) standard; compare adopters and committers with resisters relative to perceived benefits, barriers and motivating factors; and examine implementation strategies. MATERIALS AND METHODS: Chief medical officers (CMO) and ICU directors at hospitals in 6 US regions were surveyed between August 2003 and January 2004. Hospital classifications were based on level of IPS implementation pioneer (met before IPS), adopter (met after IPS by 2002 Leapfrog survey), committer (not met but committed to December 2004 implementation), and resister (refused to adopt IPS). Meeting IPS included intensivist staffing, 8 hours/day 7 days/week; sole patient care in ICU; 95% pager response time =5 minutes; and physicians certified in critical care. RESULTS: Forty-three (80%) CMOs and 42 (78%) ICU directors were interviewed. Adopters (100%), committers (80%), and resisters (45%) employed intensivists; 1 adopter (14%) met all criteria for standard. Main motivators for implementation were "quality of patient care" for CMO (79%) and ICU director (71%) adopter/committers. Incentives to implement were increasing intensivist authority (90% committers) and intensivist salary support (80% committers and 70% adopters). Main resister barriers were implementation costs (61% CMOs) and medical staff controversy (55% ICU directors). CONCLUSION: Most hospitals-including half of those who publicly resisted the standard-made attempts to change physician staffing in their ICUs, based on the criteria outlined by the Leapfrog Group. Major barriers that need addressing are implementation costs and convincing hospital organizations and medical staff regarding the benefits of adopting the standard.

PURPOSE: The aim of this study is to determine if patient safety incidents and the system-related factors contributing to them systematically differ for medical versus surgical patients in intensive care units. MATERIALS AND METHODS: We conducted a multicenter prospective study of 646 incidents involving adult medical patients and 707 incidents involving adult surgical patients that were reported to an anonymous patient safety registry over a 2-year period. We compared incident characteristics, patient harm, and associated system factors for medical versus surgical patients. RESULTS: The proportion of safety incidents reported for medical versus surgical patients differed for only 3 of 11 categories: equipment/devices (14% vs 19%; P = .02), "line, tube, or drain" events (8% vs 13%; P = .001), and computerized physician order entry (13% vs 6%; P < or = .001). The type of patient harm associated with incidents also did not differ. System factors were similar for medical versus surgical patients, with training and teamwork being the most important factors in both groups. CONCLUSIONS: Medical and surgical patients in the intensive care unit experience very similar types of safety incidents with similar associated patient harm and system factors. Common initiatives to improve patient safety for medical and surgical patients should be undertaken with a specific focus on improving training and teamwork among the intensive care team.

BACKGROUND: Sepsis is associated with increased morbidity, mortality, and costs of care. Although several therapies improve outcomes in patients with sepsis, rigorously developed measures to evaluate quality of sepsis care in the intensive care unit (ICU) are lacking. METHODS: To select an initial set of candidate measures, in 2003-2004 an interdisciplinary panel reviewed the literature and used a modified nominal group technique to identify interventions that improve outcomes of patients with sepsis in the ICU. Design specifications or explicit definitions for each candidate measure were developed. RESULTS: Ten potential measures were identified: vancomycin administration, time to vancomycin initiation, broad-spectrum antibiotic administration, time to broad-spectrum antibiotic initiation, blood culture collection, steroid administration, corticotropin stimulation test administration, activated protein C eligibility assessment, activated protein C administration, and vancomycin discontinuation. DISCUSSION: The identification of potential measures of quality of care for patients with sepsis can help caregivers to focus on evidence-based interventions that improve mortality and to evaluate their current performance. Further work is needed to evaluate the feasibility and validity of the measures.

Since their widespread introduction more than half a century ago, intensive care units (ICUs) have become an integral part of the health care system. Although most ICUs are found in high-income countries, they are increasingly a feature of health care systems in low- and middle-income countries. The World Federation of Societies of Intensive and Critical Care Medicine convened a task force whose objective was to answer the question "What is an ICU?" in an internationally meaningful manner and to develop a system for stratifying ICUs on the basis of the intensity of the care they provide. We undertook a scoping review of the peer-reviewed and gray literature to assemble existing models for ICU stratification. Based on these and on discussions among task force members by teleconference and 2 face-to-face meetings, we present a proposed definition and classification of ICUs. An ICU is an organized system for the provision of care to critically ill patients that provides intensive and specialized medical and nursing care, an enhanced capacity for monitoring, and multiple modalities of physiologic organ support to sustain life during a period of life-threatening organ system insufficiency. Although an ICU is based in a defined geographic area of a hospital, its activities often extend beyond the walls of the physical space to include the emergency department, hospital ward, and follow-up clinic. A level 1 ICU is capable of providing oxygen, noninvasive monitoring, and more intensive nursing care than on a ward, whereas a level 2 ICU can provide invasive monitoring and basic life support for a short period. A level 3 ICU provides a full spectrum of monitoring and life support technologies, serves as a regional resource for the care of critically ill patients, and may play an active role in developing the specialty of intensive care through research and education. A formal definition and descriptive framework for ICUs can inform health care decision-makers in planning and measuring capacity and provide clinicians and patients with a benchmark to evaluate the level of resources available for clinical care.

PURPOSE: To evaluate the frequency and type of factors involved in incidents reported to a patient safety reporting system and answer specific questions to enhance the value of PSRS data to improve patient safety. MATERIALS AND METHODS: Prospective cohort study of incidents reported from adult and pediatric intensive care units (ICUs) in the United States to the web-based, voluntary, and anonymous Intensive Care Unit Safety Reporting System. Results from July 1, 2002, to June 30, 2004. Main outcome variables were incidents that could or did lead to patient harm. RESULTS: Analysis includes 2075 incidents from 23 ICUs. Median number of reports/ICU/month was 3; 5 hospitals submitted 58% of reports. Harm was reported in 42% of incidents with 18 deaths. Common event types: medication/therapeutics (42%) and incorrect/incomplete care delivery (20%); 48% of line/tube/drain incidents led to physical harm. Deficiencies in training/education contributed to 49% of incidents and teamwork issues 32%; 42% of incidents had 2 or more contributing factors. As the number of contributing factors per incident increased, so did risk of harm. CONCLUSIONS: The Intensive Care Unit Safety Reporting System provides a mechanism for multiple ICUs to identify hazards. Data trends show a correlation between multiple contributing factors and higher rates of harm. Further research is needed to help determine how to use PSRS data to improve patient safety.

BACKGROUND: Cardiac troponin I (cTnI) is a highly sensitive and specific marker for myocardial injury that predicts outcomes in patients with acute coronary syndromes. Cardiovascular complications are the leading cause of morbidity and mortality in patients who have undergone vascular surgery. However, postoperative surveillance with cardiac enzymes is not routinely performed in these patients. We evaluated the association between postoperative cTnI levels and 6-month mortality and perioperative myocardial infarction (MI) after vascular surgery. METHODS AND RESULTS: Two hundred twenty-nine patients having aortic or infrainguinal vascular surgery or lower extremity amputation were included in this study. Blood samples were analyzed for cTnI immediately after surgery and the mornings of postoperative days 1, 2, and 3. An elevated cTnI was defined as serum concentrations >1.5 ng/mL in any of the 4 samples. Twenty-eight patients (12%) had postoperative cTnI >1.5 ng/mL, which was associated with a 6-fold increased risk of 6-month mortality (adjusted OR, 5.9; 95% CI, 1.6 to 22.4) and a 27-fold increased risk of MI (OR, 27.1; 95% CI, 5.2 to 142.7). Furthermore, we observed a dose-response relation between cTnI concentration and mortality. Patients with cTnI >3.0 ng/mL had a significantly greater risk of death compared with patients with levels < or =0.35 ng/mL (OR, 4.9; 95% CI, 1.3 to 19.0). CONCLUSIONS: Routine postoperative surveillance for cTnI is useful for identifying patients who have undergone vascular surgery who have an increased risk for short-term mortality and perioperative MI. Further research is needed to determine whether intervention in these patients can improve outcome.
