Toward learning from patient safety reporting systems.

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.

Patient-safety and quality initiatives in the intensive-care unit.

PURPOSE OF REVIEW: Patient safety has become the primary focus of health-care improvement in the last few years as an increasing body of evidence emphasizes the magnitude of harm posed to patients by medical errors. The intensive-care unit, by virtue of the high technology aggressive level of care the unit provides, has been identified as a significant source of patient harm. Consequently, the intensive-care unit also represents a tremendous opportunity to study and implement patient-safety initiatives, as significant improvements can be realized in this environment. RECENT FINDINGS: Several broad areas of successful patient-safety initiatives have been reported over the recent past including implementation of Comprehensive Unit-based Safety Programs, introduction of communication tools (for example daily goal sheets), application of care bundles (that is mechanical ventilation or sepsis), as well as team approaches that can eradicate catheter-related bloodstream infections. Specific interventions are gaining supportive evidence and widespread acceptance for their ability to reduce harm including tight glucose control and ultrasonography for reducing central-line placement complications. Recent data also demonstrate the value of an intensivist as the team leader for the critically ill within the intensive-care unit and potentially with rapid-response teams. SUMMARY: Many patient safety and quality-of-care initiatives that have broad application to all areas of medical care have been successfully developed in the intensive-care unit. The intensive-care unit appears to be a fertile ground for the development of safety initiatives.

Unsustainable growth rate: physician perspective.

OBJECTIVE: To describe the sustainable growth rate history and calculations and why the present approach is not sustainable. BACKGROUND: The sustainable growth rate was created to help control the growth rate in healthcare expenditures. Presently, it is responsible, at least in part, for reductions in physician payment. Two components of the sustainable growth rate make it unsustainable in its present form. These components are 1) the inability to go back and correct for values based on the wrong assumptions and 2) the inclusion of drug-related costs into the sustainable growth rate. DISCUSSION: Few physicians have a full grasp of how their payment is structured from a mechanistic standpoint. A significant component of determining physician payment is established by the relative value unit, and how these are derived has been discussed in another article in this supplement. Once the relative value unit has been established, it is multiplied by the established conversion factor. A major component of the conversion factor is the sustainable growth rate. This article attempts to explain how the sustainable growth rate came into being, how it is calculated, and how it is flawed and contributing to decreasing physician payments. A few possible remedies are discussed, and the potential ramifications of those remedies on the physician community and the premiums of Medicare patients are examined.

Evaluation and management codes: from current procedural terminology through relative update commission to Center for Medicare and Medicaid Services.

BACKGROUND: Physicians should have a working knowledge of the process by which patient care codes are created and subsequently assigned values. The Society of Critical Care Medicine has representatives on the national committees that focus on code creation and definition and on assignment of relative value units. In addition, a better understanding of documentation requirements and the audit process will facilitate improved compliance and minimize liability. DISCUSSION: The authors discuss the current procedural terminology (CPT) process for defining care codes and the relative update commission (RUC) process for assigning values to those codes, with each code assigned a separate value in three separate categories. Steps for managing any concern or dispute about billing, denials, or an audit are subsequently addressed. Tenets of proper documentation are discussed, and some future developments are identified that are likely to affect critical care. CONCLUSION: Knowledge of the procedures by which care codes are defined and valued is necessary for using these codes properly, as well as for addressing needs unmet by existing codes. Preventing audits is the best approach to proper coding and billing, and documentation is key.

Intensive care unit physician staffing: financial modeling of the Leapfrog standard.

OBJECTIVE: To evaluate from a hospital's perspective the costs and savings, over a 1-yr period, of implementing The Leapfrog Group's Intensive Care Unit Physician Staffing (IPS) standard compared with the existing standard of nonintensivist staffing in adult intensive care units. DESIGN: Using published data, we developed a financial model of costs and savings for 6-, 12- and 18-bed intensive care units using conservative estimates for all variables. Sensitivity analyses, including a best-case and worst-case scenario, were performed to evaluate the impact of changing assumptions on the outcome of the model. SETTING: Nonrural hospitals in the United States. PATIENTS: All adult intensive care unit patients. INTERVENTIONS: The IPS standard requires that intensive care units have a dedicated intensivist present during daytime hours. Outside of these hours, an intensivist must be immediately available by pager, and a physician or "physician extender" must be in the hospital and able to immediately reach intensive care unit patients. MEASUREMENTS AND MAIN RESULTS: Cost savings ranged from $510,000 to $3.3 million for 6- to 18-bed intensive care units. The best-case scenario demonstrated savings of $4.2-13 million. Under the worst-case scenario, there was a net cost of $890,000 to $1.3 million. CONCLUSIONS: Financial modeling of implementation of the IPS standard using conservative assumptions demonstrated cost savings to hospitals. Only under worst-case scenario assumptions did intensivist staffing result in additional cost to hospitals. These economic findings must be interpreted in the context of significant reductions in patient morbidity and mortality rates also associated with intensivist staffing. Given the magnitude of its clinical and financial impact, hospital leaders should be asking "how to" rather than "whether to" implement The Leapfrog Group's ICU Physician Staffing standard.

Clinical and economic outcomes of hospital acquired pneumonia in intra-abdominal surgery patients.

OBJECTIVE: To measure the clinical and economic impact of postoperative hospital-acquired pneumonia (HAP) and to identify risk factors for the development of HAP. SUMMARY BACKGROUND DATA: Although postoperative HAP is recognized to be an major risk associated with surgery, little is known about the overall outcomes of patients whose hospital stay is complicated by HAP following surgery. METHODS: We studied 618,495 patients who underwent an intra-abdominal operation from the National Inpatient Sample database over a 1-year period (January 2000 to December 2000) using CPT codes and discharge diagnoses identified by the Clinical Classification Software. Data collected included demographic characteristics, type of operation, in-hospital mortality, discharge disposition, length of stay, and hospital charges. RESULTS: Of the 13,292 patients with HAP following intra-abdominal surgery, 1421 died prior to discharge (mortality = 10.7%) compared with 7217 deaths in the control group of patients without HAP following intra-abdominal surgery (mortality = 1.2%) (P < 0.001). HAP was independently associated with a 4.13-fold (95% confidence interval = 3.94-4.34) increase in risk to be discharged to a skilled nursing facility. The mean length of hospital stay for intra-abdominal patients who developed HAP was significantly greater compared with intra-abdominal surgery patients who did not develop HAP (17.10 days versus 6.07 days, P < 0.001). After adjusting for patient characteristics, HAP was independently associated with a 75% (28,160.95 dollars; 95% confidence interval, 27,543.76 dollars - 28,778.13 dollars) mean increase in total hospital charges. CONCLUSIONS: Given the high incidence and significant impact of HAP on patient outcomes, early preventive strategies and interventions to reduce HAP should be a priority.

Integrating the intensive care unit safety reporting system with existing incident reporting systems.

BACKGROUND: Voluntary incident reporting systems that identify risks can be integrated into existing hospital reporting systems and can improve patient safety. FINDINGS: A voluntary and anonymous Web-based intensive care unit safety reporting system (ICUSRS) was implemented in a cohort of intensive care units (ICUs). The reporting system was integrated into hospitals' reporting systems after the adverse event reporting structures were investigated. Reporting systems were classified as mandatory or voluntary and internal or external; the extent of formal training was identified and the trajectory of completed adverse events in the exisiting systems were tracked. Information from reported incidents was sent back monthly to the hospital ICUs through case discussions and a quarterly newsletter. RESULTS: All seven hospitals had internal reporting systems and two also used external reporting systems. In general, the majority of incident reports were completed by registered nurses and were reported to the nursing chain of command. Many of the sites had little knowledge or understanding of their existing reporting systems. CONCLUSION: Voluntary external reporting systems such as the ICUSRS hold promise for improving patient safety.

Number needed to treat and cost of recombinant human erythropoietin to avoid one transfusion-related adverse event in critically ill patients.

OBJECTIVE: To calculate the absolute risk reduction of transfusion-related adverse events, the number of patients needed to treat, and cost to avoid one transfusion-related adverse event by using erythropoietin in critically ill patients DESIGN: Number needed to treat with sensitivity analysis. SETTING: Teaching hospital. PATIENTS: Hypothetical cohort of critically ill patients who were candidates to receive erythropoietin. INTERVENTIONS: Using vs. not using erythropoietin to reduce the need for packed red blood cell transfusions. MEASUREMENTS AND MAIN RESULTS: We used published estimates of known transfusion risks: transfusion-related acute lung injury, transfusion-related errors, hepatitis B and C, human immunodeficiency virus, human T-cell lymphotropic virus, and bacterial contamination, stratified by severity. Based on the estimated risk and frequency of transfusions with and without erythropoietin, we calculated the absolute risk reduction of transfusion-related adverse events, the number needed to treat, and cost to avoid one transfusion-related adverse event by using erythropoietin. The estimated incidence of transfusion-related adverse event was 318 permillion units transfused for all transfusion-related adverse events, 58 per million for serious transfusion-related adverse events, and 21 per million for likely fatal transfusion-related adverse events. The routine use of erythropoietin resulted in an absolute risk reduction of 191 per million for all transfusion-related adverse events, 35 per million for serious transfusion-related adverse events, and 12 per million for likely fatal transfusion-related adverse events. The number needed to treat was 5,246 to avoid one transfusion-related adverse event, 28,785 to avoid a serious transfusion-related adverse event, and 81,000 for a likely fatal transfusion-related adverse event. The total cost was $4,700,000 to avoid one transfusion-related adverse event, $25,600,000 to avoid one serious transfusion-related adverse event, and $71,800,000 to avoid a likely fatal transfusion-related adverse event. The magnitude of these results withstood extensive sensitivity analysis. CONCLUSIONS: From the perspective of avoidance of adverse events, erythropoietin does not appear to be an efficient use of limited resources for routine use in critically ill patients.

A system factors analysis of "line, tube, and drain" incidents in the intensive care unit.

OBJECTIVE: To analyze the system factors related to "line, tube, and drain" (LTD) incidents in the intensive care unit (ICU). DESIGN: Voluntary, anonymous Web-based patient safety reporting system. SETTING: Eighteen ICUs in the United States. PATIENTS: Incidents reported by ICU staff members during a 12-month period ending June 2003. INTERVENTIONS: None. MEASUREMENTS: Characteristics of the incidents (defined as events that could/did cause harm), patients, and patient harm were described. Separate multivariable logistic regression analyses of contributing, limiting, and preventive system factors for LTD vs. non-LTD incidents were reported. MAIN RESULTS: Of the 114 reported LTD incidents, >60% were considered preventable. One patient death was attributed to an LTD incident. Of patients experiencing LTD incidents, 56% sustained physical injury, and 23% had an anticipated increased hospital stay. Factors contributing to LTD incidents included occurrence in the operating room (odds ratio [OR], 3.50; 95% confidence interval [CI], 1.25-9.83), occurrence on a holiday (OR, 3.65; 95% CI, 1.12-11.9), patient medical complexity (OR, 3.68; 95% CI, 2.28-5.92), and age of 1-9 yrs (OR, 7.95; 95% CI, 3.29-19.2). Factors related to team communication were less likely to limit LTD incidents (OR, 0.28; 95% CI, 0.11-0.68), while clinician knowledge and skills helped prevent LTD incidents (OR, 1.80; 95% CI, 1.09-2.97). CONCLUSIONS: Patients are harmed by preventable LTD incidents. Relative to non-LTD events, these incidents occur more frequently during holidays and in medically complex patients and children. Focusing on these contributing factors and clinician knowledge and skills is important for reducing and preventing these hazardous events.

Do intensivists in ICU improve outcome?

Despite considerable investment of resources, there remains wide variation in organization of Intensive Care Units (ICUs). One key domain is the physician staffing. In particular, does staffing with physicians trained in critical care (intensivists) improve clinical outcomes? The rationale for improved outcome with intensivist staffing is that physicians who have the skills to treat critically ill patients, and who are immediately available to detect and treat problems, may prevent or attenuate morbidity and mortality. Intensivist staffing may also yield benefits through a leadership role at the intensive care unit organizational level. The improved sense of continuity and close attendance to patients may also bolster improved patient and family satisfaction. Intensivist-led or intensivist-staffed ICUs may also realize decreased resource use because these physicians may be better at reducing inappropriate admissions, preventing complications that prolong length of stay, and recognizing opportunities for prompt discharge.

Creating the web-based intensive care unit safety reporting system.

In an effort to improve patient safety, researchers at the Johns Hopkins University designed and implemented a comprehensive Web-based Intensive Care Unit Safety Reporting System (ICUSRS). The ICUSRS collects data about adverse events and near misses from all staff in the ICU. This report reflects data on 854 reports from 18 diverse ICUs across the United States. Reporting is voluntary, and data collected is confidential, with patient, provider, and reporter information deidentified. Preliminary data include system factors reported, degree of patient harm, reporting times, and evaluations of the system. Qualitative and quantitative data are reported back to the ICU site study teams and frontline staff through monthly reports, case discussions, and a quarterly newsletter.

Improving care for the ventilated patient.

CONTEXT: Despite evidence that the use of specific interventions can decrease morbidity and mortality for patients receiving mechanical ventilation, a gap exists between best evidence and practice. A prospective cohort study was conducted in a surgical intensive care unit (ICU) that included all patients who were mechanically ventilated. The study was designed to ensure that for 90% of ventilator days, patients receive processes associated with improved outcomes, including semirecumbent positioning, daily interruption of sedative-drug infusions, peptic ulcer disease prophylaxis, and deep venous thrombosis prophylaxis. INTERVENTION: The improvement model included three interventions: (1) administering a questionnaire to identify barriers to compliance with the four care processes, (2) implementing an educational intervention, and (3) implementing a checklist to be completed daily during ICU rounds to ask providers whether patients were receiving these therapies. RESULTS: Overall, 80% of nurses did not know there was evidence to support at least one of the four therapies. During the study period (March 4-April 29, 2002), the percentage of ventilator days on which patients received all four care processes increased from 30% to 96% (p < .001). DISCUSSION: Evidence-based therapies for mechanically ventilated patients can reduce morbidity, mortality, and costs of care.

Platelet gene polymorphisms and cardiac risk assessment in vascular surgical patients.

BACKGROUND: Current perioperative cardiac risk assessment tools use historic and surgical factors to stratify patient risk. Polymorphisms in platelet glycoprotein (GP) IIIa and GPIbalpha are associated with myocardial ischemic risk in nonsurgical settings, but their relation to perioperative ischemia is unclear. The authors hypothesized that platelet genotype would be an independent predictor of postoperative myocardial ischemia and would improve risk assessment when added to clinical factors. METHODS: One hundred ninety-six patients who underwent infrainguinal, abdominal aortic, or thoracoabdominal vascular surgery were evaluated for clinical and genetic factors that might predict the development of postoperative myocardial ischemia. Genomic DNA was genotyped for the Leu33Pro polymorphism of GPIIIa and the Thr145Met polymorphism of GPIbalpha. Myocardial ischemic outcome was determined by review of the medical record for cardiac death or myocardial infarction and by surveillance troponin I and automated continuous 12-lead electrocardiographic analysis. RESULTS: Sixty-five patients (33%) experienced one or more ischemic endpoints (2% death, 5% myocardial infarction, 20% troponin+, 22% electrocardiogram+). The Pro33 (adjusted odds ratio [OR], 2.4 [95% confidence interval, 1.2-6.2]) and Met145 (OR 3.4 [1.4-9.3]) genotypes were independent predictors of composite ischemic outcome by multivariate regression, as were diabetes mellitus (OR 4.0 [1.7-12.5]), abdominal aortic surgery (OR 4.1 [1.7-14.4]), and thoracoabdominal aortic surgery (OR 6.4 [2.7-23.8]). The addition of platelet gene polymorphisms to clinical factors improved fit (likelihood ratio testing chi-square = 13.5, P < 0.001) of an ischemia prediction model. The derived risk assessment tool had a receiver operator characteristic curve of 0.73 (0.65-0.81) compared with 0.64 (0.57-0.74) for a model excluding genetic factors (P = 0.04). A significant relation between the GPIbalpha polymorphism and ischemic outcome remained after excluding electrocardiographic ischemia from the composite endpoint. CONCLUSIONS: Platelet polymorphisms are independent risk factors for postoperative myocardial ischemia and improve a risk prediction model when added to historic and surgical risk factors.

Guidelines for critical care medicine training and continuing medical education.

OBJECTIVE: Critical care medicine trainees and faculty must acquire and maintain the skills necessary to provide state-of-the art clinical care to critically ill patients, to improve patient outcomes, optimize intensive care unit utilization, and continue to advance the theory and practice of critical care medicine. This should be accomplished in an environment dedicated to compassionate and ethical care. PARTICIPANTS: A multidisciplinary panel of professionals with expertise in critical care education and the practice of critical care medicine under the direction of the American College of Critical Care Medicine. SCOPE: Physician education in critical care medicine in the United States should encompass all disciplines that provide care in the intensive care unit and all levels of training: from medical students through all levels of postgraduate training and continuing medical education for all providers of clinical critical care. The scope of this guideline includes physician education in the United States from residency through ongoing practice after subspecialization. DATA SOURCES AND SYNTHESIS: Relevant literature was accessed via a systematic Medline search as well as by requesting references from all panel members. Subsequently, the bibliographies of obtained literature were reviewed for additional references. In addition, a search of organization-based published material was conducted via the Internet. This included but was not limited to material published by the American College of Critical Care Medicine, Accreditation Council for Graduate Medical Education, Accreditation Council for Continuing Medical Education, and other primary and specialty organizations. Collaboratively and iteratively, the task force met, by conference call and in person, to construct the tenets and ultimately the substance of this guideline. CONCLUSIONS: Guidelines for the continuum of education in critical care medicine from residency through specialty training and ongoing throughout practice will facilitate standardization of physician education in critical care medicine.

Intensive care unit physician staffing: financial modeling of the Leapfrog standard.

OBJECTIVE: To evaluate from a hospital's perspective the costs and savings, over a 1-yr period, of implementing The Leapfrog Group's Intensive Care Unit Physician Staffing (IPS) standard compared with the existing standard of nonintensivist staffing in adult intensive care units. DESIGN: Using published data, we developed a financial model of costs and savings for 6-, 12- and 18-bed intensive care units using conservative estimates for all variables. Sensitivity analyses, including a best-case and worst-case scenario, were performed to evaluate the impact of changing assumptions on the outcome of the model. SETTING: Nonrural hospitals in the United States. PATIENTS: : All adult intensive care unit patients. INTERVENTIONS: The IPS standard requires that intensive care units have a dedicated intensivist present during daytime hours. Outside of these hours, an intensivist must be immediately available by pager, and a physician or "physician extender" must be in the hospital and able to immediately reach intensive care unit patients. MEASUREMENTS AND MAIN RESULTS: Cost savings ranged from 510,000 to 3.3 million US dollars for 6- to 18-bed intensive care units. The best-case scenario demonstrated savings of 4.2-13 million US dollars. Under the worst-case scenario, there was a net cost of 890,000 to 1.3 million US dollars. CONCLUSIONS: Financial modeling of implementation of the IPS standard using conservative assumptions demonstrated cost savings to hospitals. Only under worst-case scenario assumptions did intensivist staffing result in additional cost to hospitals. These economic findings must be interpreted in the context of significant reductions in patient morbidity and mortality rates also associated with intensivist staffing. Given the magnitude of its clinical and financial impact, hospital leaders should be asking "how to" rather than "whether to" implement The Leapfrog Group's ICU Physician Staffing standard.

Eliminating catheter-related bloodstream infections in the intensive care unit.

OBJECTIVE: To determine whether a multifaceted systems intervention would eliminate catheter-related bloodstream infections (CR-BSIs). DESIGN: Prospective cohort study in a surgical intensive care unit (ICU) with a concurrent control ICU. SETTING: The Johns Hopkins Hospital. PATIENTS: All patients with a central venous catheter in the ICU. INTERVENTION: To eliminate CR-BSIs, a quality improvement team implemented five interventions: educating the staff; creating a catheter insertion cart; asking providers daily whether catheters could be removed; implementing a checklist to ensure adherence to evidence-based guidelines for preventing CR-BSIs; and empowering nurses to stop the catheter insertion procedure if a violation of the guidelines was observed. MEASUREMENT: The primary outcome variable was the rate of CR-BSIs per 1,000 catheter days from January 1, 1998, through December 31, 2002. Secondary outcome variables included adherence to evidence-based infection control guidelines during catheter insertion. MAIN RESULTS: Before the intervention, we found that physicians followed infection control guidelines during 62% of the procedures. During the intervention time period, the CR-BSI rate in the study ICU decreased from 11.3/1,000 catheter days in the first quarter of 1998 to 0/1,000 catheter days in the fourth quarter of 2002. The CR-BSI rate in the control ICU was 5.7/1,000 catheter days in the first quarter of 1998 and 1.6/1,000 catheter days in the fourth quarter of 2002 (p = .56). We estimate that these interventions may have prevented 43 CR-BSIs, eight deaths, and 1,945,922 dollars in additional costs per year in the study ICU. CONCLUSIONS: Multifaceted interventions that helped to ensure adherence with evidence-based infection control guidelines nearly eliminated CR-BSIs in our surgical ICU.
