Creating high reliability in health care organizations.

OBJECTIVE: The objective of this paper was to present a comprehensive approach to help health care organizations reliably deliver effective interventions. CONTEXT: Reliability in healthcare translates into using valid rate-based measures. Yet high reliability organizations have proven that the context in which care is delivered, called organizational culture, also has important influences on patient safety. MODEL FOR IMPROVEMENT: Our model to improve reliability, which also includes interventions to improve culture, focuses on valid rate-based measures. This model includes (1) identifying evidence-based interventions that improve the outcome, (2) selecting interventions with the most impact on outcomes and converting to behaviors, (3) developing measures to evaluate reliability, (4) measuring baseline performance, and (5) ensuring patients receive the evidence-based interventions. The comprehensive unit-based safety program (CUSP) is used to improve culture and guide organizations in learning from mistakes that are important, but cannot be measured as rates. CONCLUSIONS: We present how this model was used in over 100 intensive care units in Michigan to improve culture and eliminate catheter-related blood stream infections--both were accomplished. Our model differs from existing models in that it incorporates efforts to improve a vital component for system redesign--culture, it targets 3 important groups--senior leaders, team leaders, and front line staff, and facilitates change management-engage, educate, execute, and evaluate for planned interventions.

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.

Incidents relating to the intra-hospital transfer of critically ill patients. An analysis of the reports submitted to the Australian Incident Monitoring Study in Intensive Care.

OBJECTIVE: Transportation of critically ill patients within the hospital poses important risks. We sought to identify causes, outcomes and contributing factors associated with intra-hospital transport. DESIGN: Cross-sectional case review. SETTING: Incident reports submitted to the Australian Incident Monitoring Study in Intensive Care (AIMS-ICU). MEASUREMENT AND MAIN RESULTS: Between 1993 and 1999, 176 reports were submitted describing 191 incidents. Seventy-five reports (39%) identified equipment problems, relating prominently to battery/power supply, transport ventilator and monitor function, access to patient elevators and intubation equipment. Hundred sixteen reports (61%) identified patient/staff management issues including poor communication, inadequate monitoring, incorrect set-up of equipment, artificial airway malpositioning and incorrect positioning of patients. Serious adverse outcomes occurred in 55 reports (31%) including major physiological derangement (15%), patient/relative dissatisfaction (7%), prolonged hospital stay (4%), physical/psychological injury (3%) and death (2%). Of 900 contributing factors identified, 46% were system-based and 54% human-based. Communication problems, inadequate protocols, in-servicing/training and equipment were prominent equipment-related incidents. Errors of problem recognition and judgement, failure to follow protocols, inadequate patient preparation, haste and inattention were common management-related incidents. Rechecking the patient and equipment, skilled assistance and prior experience were important factors limiting harm. CONCLUSIONS: Intra-hospital transport poses an important risk to ICU patients. The adequate provision of highly qualified staff, specially designed and well maintained equipment, as well as continuous monitoring are essential to avoid/mitigate these incidents. Professional societies and local units should adopt guidelines/protocols for intra-hospital transportation. Monitoring of incidents should aid in the continuous improvement in patient safety.

Interventions to reduce mortality among patients treated in intensive care units.

PURPOSE: Using sensitivity analysis to estimate the impact, in terms of patient lives, of the failure to use proven therapies known to reduce mortality in critically ill intensive care unit patients. MATERIALS AND METHODS: We identified high-impact interventions published in the last 5 years in the Journal of the American Medical Association or New England Journal of Medicine, extracted the absolute risk reduction associated with each intervention and gleaned the national incidence of each condition and the percent of the population not receiving the cited therapy from the literature. From this information, we calculated national estimates of the excess deaths from failure to use these therapies. RESULTS: With consistent and appropriate implementation of the 5 cited evidence-based interventions, we found a total of 167,819 lives could be saved per year, with a range of 137,670 to 197,965 lives saved per year. CONCLUSIONS: Mistakes of omission are common in the critical care setting and lead to significant preventable mortality. There is a significant gap between the discovery of effective interventions and their use in clinical practice. By viewing the delivery of healthcare as a science and increasing funding for health services research, we may be able to increase the use of effective therapies and, as a result, reduce patient mortality.

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.

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.

Peripherally inserted central catheters: a randomized, controlled, prospective trial in pediatric surgical patients.

Peripherally-inserted central catheters (PICCs) are long-term IV catheters used for drug and fluid administration, blood sampling, or hyperalimentation. The short-term use of PICCs in postoperative patients has not been studied. In this randomized, controlled trial, patients received either a PICC or peripheral IV catheter (PIV). Our outcome measures were patient and parent satisfaction with care, complications of the venous access devices, number of postoperative venipunctures, and cost-effectiveness of use. Satisfaction was significantly more frequent in the PICC group (P < 0.05), and there were significantly fewer postoperative needle punctures in the PICC group compared with the PIV group (P < 0.05). Minor complications were common in the PIV group; major complications were uncommon in both groups. PICCs are more expensive, but better satisfaction can make them a cost-effective option. Additionally, insertion during surgical preparation time in the operating room (OR) means that cost is not increased by adding anesthesiologist and OR time. Anesthesiologists should consider placing PICCs in patients requiring more than 4 days of in-hospital postoperative care, especially if frequent blood sampling or IV access is required.

Developing and pilot testing quality indicators in the intensive care unit.

PURPOSE: To develop and implement a set of valid and reliable yet practical measures of intensive care units (ICU) quality of care in a cohort of ICUs and to estimate, based on current performance, the potential opportunity to improve quality. METHODS: We included 13 adult medical and surgical ICUs in urban community teaching and community hospitals. To monitor performance on previously identified quality measures, we developed 3 data collection tools: the Team Leader, Daily Rounding, and Infection Control forms. These tools were pilot tested, validated, and modified before implementation. We used published estimates of efficacy to estimate the clinical and economic effect of our current performance for each of the process measures: appropriate sedation, prevention of ventilator-associated pneumonia, appropriate peptic ulcer disease (PUD) prophylaxis, appropriate deep venous thrombosis (DVT) prophylaxis, and appropriate use of blood transfusions. RESULTS: Performance varied widely among the 13 ICUs and within ICUs. The median percentage of days in which ventilated patients received therapies that ought to was 64% for appropriate sedation, 67% for elevating head of bed, 89% for PUD prophylaxis, and 87% for DVT prophylaxis. The median rate of appropriate transfusion was 33%. The failure to use these therapies may lead to excess morbidity, mortality, and ICU length of stay. CONCLUSION: To improve quality of care, we must measure our performance. This pilot study suggests that it is feasible to implement a broad set of ICU quality measures in a cohort of hospitals. By improving performance on these measures, we may realize reduced mortality, morbidity, and ICU length of stay.

Epidemiology and impact of aspiration pneumonia in patients undergoing surgery in Maryland, 1999-2000.

OBJECTIVE: The epidemiology of aspiration pneumonia and its impact on clinical and economic outcomes in surgical patients are poorly defined. We sought to identify preoperative patient characteristics and surgical procedures that are associated with an increased risk for aspiration pneumonia and to determine the clinical and economic impact in hospitalized surgical patients. DESIGN: Observational study using a state discharge database. SETTING: All hospitals in Maryland. PATIENTS: We obtained discharge data for 318,880 adult surgical patients in 52 Maryland hospitals from January 1, 1999, through December 31, 2000. MEASUREMENTS AND MAIN RESULTS: The primary outcome variable was a discharge diagnosis of aspiration pneumonia. Unadjusted and adjusted analyses were performed to identify patient characteristics and surgical procedures associated with an increased risk for aspiration pneumonia and to determine the impact on intensive care unit admission, in-hospital mortality, hospital length of stay, and total hospital charges. The overall prevalence of aspiration pneumonia was 0.8%. The prevalence varied among hospitals (range, 0% to 1.9%) and by surgical procedure (range, <0.1% to 19.1%). Patient characteristics independently associated with an increased risk included: male sex, nonwhite race, age of >60 yrs vs. 18-29 yrs, dementia, chronic obstructive pulmonary disease, renal disease, malignancy, moderate to severe liver disease, and emergency room admission. In patients undergoing procedures other than tracheostomy, aspiration pneumonia was independently associated with an increased risk for admission to the intensive care unit (odds ratio, 4.0; 95% confidence interval, 3.0-5.1), in-hospital mortality (odds ratio, 7.6; 95% confidence interval, 6.5-8.9), longer hospital length of stay (estimated mean increase of 9 days; 95% confidence interval, 8-10), and increased total hospital charges (estimated mean increase of 22,000 US dollars; 95% confidence interval, 19,000 US dollars-25,000 US dollars). CONCLUSIONS: Aspiration pneumonia occurs in approximately 1% of surgical patients and is associated with significant morbidity, mortality, and costs of care. Given that the rate of aspiration pneumonia varies among hospitals, we can improve the quality and reduce the costs of care by implementing strategies to reduce the rate of aspiration pneumonia.

Predictors of transfusion for spinal surgery in Maryland, 1997 to 2000.

BACKGROUND: The purpose of this study was to identify preoperative patient, hospital, and surgeon characteristics associated with transfusion for spinal surgery. STUDY DESIGN AND METHODS: Discharge data were obtained from 39 Maryland hospitals for adult patients (n = 3988) who had a primary procedure code for spinal surgery between July 1997 through June 2000, and with these codes, surgeons and hospitals were characterized by annual patient volume. Outcome variables included any allogeneic transfusion, any transfusion, RBCs, autologous blood, FFP, or platelet transfusion. Logistic regression was used for univariate and multivariate analyses. RESULTS: Characteristics independently associated with an increased risk of receiving any allogeneic transfusion (n = 786) included age >54 (OR, 1.6; 95% CI, 1.3-2.1), age >66 (OR, 2.7; 95% CI, 2.0-3.5), female sex (OR, 1.6; 95% CI, 1.2-2.0), diabetes with chronic complications (OR, 2.5; 95% CI, 1.3-4.9), and metastatic tumor (OR, 4.9; 95% CI, 2.3-10.5), emergency room admission (OR, 2.3; 95% CI, 1.4-3.8), and greater hospital volume (OR, 4.0; 95% CI, 1.8-8.6). Characteristics independently associated with increased autologous transfusions (n = 574) included white race (OR, 1.7; 95% CI, 1.2-2.4), female sex (OR, 1.4; 95% CI, 1.1-1.8), and greater surgeon volume (OR, 3.5; 95% CI, 1.4-9.1). DISCUSSION: This information can be used to provide informed risk-benefit discussions with patients regarding the risk for blood transfusion as well as to target high-risk patients and institutions for interventions to reduce the risk of exposure to blood components.

Qualitative review of intensive care unit quality indicators.

PURPOSE: The purpose of this study was to (1) conduct a systematic review of the literature to identify interventions that improve patient outcomes in the intensive care unit (ICU); (2) evaluate potential measures of quality based on the impact, feasibility, variability, and the strength of evidence to support each measure and to categorize these measures as outcome, process, access, or complication measures; and (3) select a list of candidate quality measures that can be broadly applied to improve ICU care. METHODS: We identified and independently reviewed all studies in Medline (1965-2000) and The Cochrane Library (Issue 3, 2001) that met the following criteria: design: observational studies, experimental trials, or systematic reviews; population: critically ill adults; and intervention: process or structure measure that was associated with improved patient outcomes: morbidity, mortality, complications, errors, costs, length of stay (LOS), and patient reported outcomes. Studies were grouped into categories by the type of outcome that was improved by the intervention. Potential quality measures were evaluated for: impact on morbidity, mortality, and costs; feasibility of the measure; and variability in the measure. We evaluated the strength of evidence for each intervention used to improve outcomes and using the Delphi method, assigned an over-all recommendation for each quality measure. RESULTS: A total of 3,014 citations were identified. Sixty-six studies that met selection criteria reported on a variety of interventions that were associated with improved patient outcomes. We identified 6 outcome measures: ICU mortality rate, ICU LOS greater than 7 days, average ICU LOS, average days on mechanical ventilation, suboptimal management of pain, and patient/family satisfaction; 6 process measures: effective assessment of pain, appropriate use of blood transfusions, prevention of ventilator-associated pneumonia, appropriate sedation, appropriate peptic ulcer disease prophylaxis, and appropriate deep venous thrombosis prophylaxis; 4 access measures: rate of delayed admissions, rate of delayed discharges, cancelled surgical cases, and emergency department by-pass hours; and 3 complication measures: rate of unplanned ICU readmission, rate of catheter-related blood stream infections, and rate of resistant infections. CONCLUSIONS: Further work is needed to create operational definitions and to pilot test the selected measures. The value of these measures will be determined by our ability to evaluate our current performance and implement interventions designed to improve the quality of ICU care.

Preoperative predictors of blood transfusion in colorectal cancer surgery.

Transfusion is associated with multiple risks and morbidities. Little is known, however, about preoperative predictors of transfusion in gastrointestinal surgery patients. To identify factors that influence transfusion practices, we analyzed hospital discharge data from colorectal cancer surgery patients in Maryland between 1994 and 2000 (n = 14,052). The primary outcome variable was whether or not patients received a blood product ("Any Transfusion"). Characteristics independently associated with an increased risk of receiving Any Transfusion included: advanced age (>80 yr: OR 2.3; 95% CI 1.9-2.9; 70-79 yr: OR 1.6; 95% CI 1.4-2.0 vs. <60 yr), moderate to severe liver disease (OR 2.5; 95% CI 1.5-4.2), mild liver disease (OR 2.1; 95% CI 1.5-2.9), diabetes with complications (OR 2.1; 95% CI 1.6-2.6), chronic renal disease (OR 2.1; 95% CI 1.4-3.0), female gender (OR 1.3; 95% CI 1.2-1.5), chronic pulmonary disease (COPD) (OR 1.3; 95% CI 1.1-1.4), and metastatic disease (OR 1.2; 95% CI 1.1-1.4). Patients at hospitals with an annual case volume in the highest quartile were at an increased risk for receiving Any Transfusion (OR 2.1; 95% CI 1.3-3.4) and those with surgeons in the highest volume quartile (>12 cases/yr) were at a decreased risk (OR 0.8; 95% CI 0.6-0.99). The association between greater surgeon case volume and low transfusion rates was seen in all but the very high volume hospitals (>74 cases/yr). Blood product transfusion was associated with a 2.5-fold (95% CI 2.1-3.1) increased mortality, 3.7 day (95% CI 2.1-3.1) increase in hospital length of stay, and a 7120 dollars (95% CI 6472 dollars-7769 dollars) increase in total charges compared to patients that did not receive Any Transfusion. This data can be used by providers in discussions with patients regarding the risks for transfusion and in identifying patients in whom strategies to reduce transfusions should be evaluated.
