Context Although medical injuries are recognized as a major hazard in the health care system, little is known about their impact. Objective To assess excess length of stay, charges, and deaths attributable to medical injuries during hospitalization. Design, Setting, and Patients The Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators (PSIs) were used to identify medical injuries in 7.45 million hospital discharge abstracts from 994 acute-care hospitals across 28 states in 2000 in the AHRQ Healthcare Cost and Utilization Project Nationwide Inpatient Sample database. Main Outcome Measures Length of stay, charges, and mortality that were recorded in hospital discharge abstracts and were attributable to medical injuries according to 18 PSIs. Results Excess length of stay attributable to medical injuries ranged from 0 days for injury to a neonate to 10.89 days for postoperative sepsis, excess charges ranged from $0 for obstetric trauma (without vaginal instrumentation) to $57727 for postoperative sepsis, and excess mortality ranged from 0% for obstetric trauma to 21.96% for postoperative sepsis (PϽ.001). Following postoperative sepsis, the second most serious event was postoperative wound dehiscence, with 9.42 extra days in the hospital, $40323 in excess charges, and 9.63% attributable mortality. Infection due to medical care was associated with 9.58 extra days, $38656 in excess charges, and 4.31% attributable mortality. Conclusion Some injuries incurred during hospitalization pose a significant threat to patients and costs to society, but the impact of such injury is highly variable.

Overall inappropriate medication use in elderly patients remains a serious problem. Despite challenges in using explicit criteria for assessing inappropriate medications for elderly patients, such criteria can be applied to population-based surveys to identify opportunities to improve quality of care and patient safety. Enhancements of existing data sources to include dosage, duration, and indication may augment national improvement and monitoring efforts.

WHAT'S KNOWN ON THIS SUBJECT:CA-BSIs are a significant source of morbidity, mortality, and added medical costs to hospitalized adult and pediatric patients. Despite these data, strategies for reducing health care complications such as pediatric CA-BSIs have received relatively little attention. WHAT THIS STUDY ADDS:In contrast with adult ICU care, maximizing insertion-bundle compliance alone cannot help PICUs to eliminate CA-BSIs. Instead, the main drivers for additional reductions in pediatric CA-BSI rates seem to be issues surrounding daily maintenance care for central lines.abstract OBJECTIVE: Despite the magnitude of the problem of catheter-associated bloodstream infections (CA-BSIs) in children, relatively little research has been performed to identify effective strategies to reduce these complications. In this study, we aimed to develop and evaluate effective cathetercare practices to reduce pediatric CA-BSIs. STUDY DESIGN AND METHODS:Our study was a multi-institutional, interrupted time-series design with historical control data and was conducted in 29 PICUs across the United States. Two central venous catheter-care practice bundles comprised our intervention: the insertion bundle of pediatric-tailored care elements derived from adult efforts and the maintenance bundle derived from the Centers for Disease Control and Prevention recommendations and expert pediatric clinician consensus. The bundles were deployed with quality-improvement teaching and methods to support their adoption by teams at the participating PICUs. The main outcome measures were the rate of CA-BSIs from January 2004 to September 2007 and compliance with each element of the insertion and maintenance bundles from October 2006 to September 2007. RESULTS:Average CA-BSI rates were reduced by 43% across 29 PICUs (5.4 vs 3.1 CA-BSIs per 1000 central-line-days; P Ͻ .0001). By September 2007, insertion-bundle compliance was 84% and maintenance-bundle compliance was 82%. Hierarchical regression modeling showed that the only significant predictor of an observed decrease in infection rates was the collective use of the insertion and maintenance bundles, as demonstrated by the relative rate (RR) and confidence intervals (CIs) (RR: 0.57 [95% CI: 0.45-0.74]; P Ͻ .0001). We used comparable modeling to assess the relative importance of the insertion versus maintenance bundles; the results showed that the only significant predictor of an infection-rate decrease was maintenancebundle compliance (RR: 0.41 [95% CI: 0.20 -0.85]; P ϭ .017). CONCLUSIONS:In contrast with adult ICU care, maximizing insertionbundle compliance alone cannot help PICUs to eliminate CA-BSIs. The main drivers for additional reductions in pediatric CA-BSI rates are issues that surround daily maintenance care for central lines, as defined in our maintenance bundle. Additional research is needed to define the optimal maintenance bundle that will facilitate elimination of CA-BSIs for children. Catheter-associated bloodstream infections (CA-BSIs) are a significant cause of morbidity, morta...

Measures based on routinely collected data would be useful to examine the epidemiology of patient safety. Extending previous work, we established the face and consensual validity of twenty Patient Safety Indicators (PSIs). We generated a national profile of patient safety by applying these PSIs to the HCUP Nationwide Inpatient Sample. The incidence of most nonobstetric PSIs increased with age and was higher among African Americans than among whites. The adjusted incidence of most PSIs was highest at urban teaching hospitals. The PSIs may be used in AHRQ's National Quality Report, while providers may use them to screen for preventable complications, target opportunities for improvement, and benchmark performance.
