Studies suggest variable adoption of evidence-based practice guidelines. The authors hypothesized that compliance with guidelines for patients requiring mechanical ventilation would vary among academic medical centers and that this variation might be associated with survival. A total of 1463 intensive care unit cases receiving continuous mechanical ventilation for >96 hours were reviewed. The variation in mortality based on compliance with 6 evidence-based practices was determined, and the effect of each intervention was estimated using a logistic regression model. Compliance varied widely across the participating centers. A strong association with survival was seen for 2 of the 6 practices: sedation management and glycemic control (odds ratios for death of 0.30 and 0.46, respectively, each P < .01). Spontaneous breathing trials, deep venous thrombosis prophylaxis, semi-recumbent positioning, and stress ulcer prophylaxis were not associated with survival in the model. More consistent adoption of these practices represents an opportunity for academic medical centers and was associated with enhanced survival. [ABSTRACT FROM AUTHOR]

Background: Debates continue regarding optimal structures for governance and administration between medical schools and their teaching hospitals., Methods: Structural integration (SI) for 85 academic health centers was characterized as high (single leader or fiduciary) or low (multiple leaders or fiduciaries). Functional alignment (FA) was estimated from questionnaire responses by teaching hospitals' chief executive officers, and an index was calculated quantifying organizational collaboration across several functional areas. SI and FA were examined for their association with global performance measures in teaching, research, clinical care, finance, and efficiency., Results: AHCs with high SI had significantly higher FA, though overlap between high-SI and low-SI institutions was considerable. SI was not significantly associated with any performance measure. In contrast, FA was significantly associated with higher performance in teaching, research, and finance but not clinical care and efficiency., Conclusions: FA between medical schools and their primary teaching hospitals more strongly predicts academic health centers' performance than does SI. As demands for greater collaboration increase under health reform, emphasis should be placed on increasing FA rather than SI., (Copyright © 2011 Elsevier Inc. All rights reserved.)

Background: External reporting of medical errors a adverse events enables learning from the errors of others in the pursuit of systems-level improvements that can prevent future errors. It is logical to presume that medication errors involving the use of anticoagulants, among the most frequently cited product classes involved in harmful medication errors, would be captured in a variety of patient safety reporting programs., Methods: Data on reported errors involving the anticoagulant heparin were reviewed, compared, and aggregated from the databases of three large patient safety reporting programs-MEDMARX, the Pennsylvania Patient Safety Authority's Patient Safety Reporting System, and the University Health System Consortium, together representing more than 1,000 reporting organizations for 2005, Results: Approximately 300,000 medication errors and near misses were reported to the programs, and 10,359-a mean of 3.6% (range, 3.1%-5.5%)-involved heparin products. The proportion of heparin-related reports that involved patient harm ranged from 1.4% to 4.9%. The phase of the medication use process cited most frequently in harmful events was the administration phase (56% of errors leading to harm), followed by the prescribing phase (19% of errors leading to harm)., Discussion: This study represents the first attempt by these three large reporting systems to combine data on a single clinical process. The consistent patterns evident in the reports, such as the percentage of all medication errors that involved heparin, suggests that reporting programs, at least for common events such as medication errors, may reach a point of diminishing returns in which aggregating more reports of a certain type yields no additional insight once a large volume of similar events is captured and analyzed.

Purpose: The relationship of the quality of teaching hospitals' clinical performance to resident education in quality and patient safety is unclear. The authors studied residents' knowledge of these areas in major teaching hospitals with higher- and lower-quality performance rankings. They assessed the presence of formal and informal quality curricula to determine whether programmatic differences exist., Method: The authors used qualitative research methodology with purposeful sampling. They gathered data from individual structured interviews with residents and key educational and quality leaders in six medical schools and teaching hospitals, which represented a range of quality performance rankings, geographic regions, and public or private status., Results: No relationship emerged between a hospital's quality status, residents' curriculum, and the residents' understanding of quality. Residents' definitions of quality and safety and their knowledge of the practice-based learning and systems-based practice competencies were indistinguishable between hospitals. Residents in all programs had extensive patient safety knowledge acquired through an informal curriculum in the hospital setting. A formal curriculum existed in only two programs, both of them ambulatory settings., Conclusions: Residents' learning about quality and patient safety is extensive, largely through a positive informal curriculum in the teaching hospital and, less frequently, via a formal curriculum. No relationship was found between the quality performance of the teaching hospital and the residents' curriculum or understanding of quality or safety. Residents seem to learn through an informal curriculum provided by hospital initiatives and resources, and thus these data suggest the importance of major teaching hospitals in quality education.

Purpose: Leaders of academic medical centers (AMCs) are challenged to ensure consistent high performance in quality and safety across all clinical services. The authors sought to identify organizational factors associated with AMCs that stood out from their peers in a composite scoring system for quality and safety derived from patient-level data., Method: A scoring method using measures of safety, mortality, clinical effectiveness, and equity of care was applied to discharge abstract data from 79 AMCs for 2003-2004. Six institutions (three top and three average performers) were selected for site visits; the performance status of the six institutions was withheld from the site visit team. Through interviews and document review, the team sought to identify factors that were associated with the performance status of the institution., Results: The scoring system discriminated performance among the 79 AMCs in a clinically meaningful way. For example, the transition of a typical 500-bed hospital from average to top levels of performance could result in 150 fewer deaths per year. Abstraction of key findings from the interview notes revealed distinctive themes in the top versus average performers. Common qualities shared by top performers included a shared sense of purpose, a hands-on leadership style, accountability systems for quality and safety, a focus on results, and a culture of collaboration., Conclusions: Distinctive leadership behaviors and organizational practices are associated with measurable differences in patient-level measures of quality and safety.

Background: The introduction of heated circuits and sealed, single-use humidifiers has prompted some investigators to question the traditional recommendations for changing ventilator circuits. We studied the clinical and cost impact of extending the circuit change interval from 72 hours to 7 days in our two intensive care units with 17 beds., Methods: With standard surveillance definitions from the Centers for Disease Control and Prevention and the National Nosocomial Infections Surveillance System, baseline pneumonia rates were established for a 3-month period. After the institution of weekly circuit changes, daily surveillance of intubated patients was performed during 18 of 22 weeks from May through September 1993. Standard microbiologic methods were used for the identification of patient and environmental isolates., Results: Ventilator-associated pneumonia for the 72-hour circuit change group was 9.1% or 1.29 per 100 ventilator days. After the institution of weekly changes, pneumonia occurred in 9 of 146 patients (6.2% or 0.74 per 100 ventilator days chi 2 = 0.33, p = 0.44). No common bacterial isolates were recovered as judged by phenotype, biochemical, or antimicrobial susceptibility patterns. Weekly changes reduced the number of circuits used from a predicted 469 to 214. Estimating $26.46 per circuit change, annualized cost savings were $20,246.90., Conclusions: Weekly circuited changes in patients undergoing ventilation therapy in the intensive care unit are cost-effective and do not contribute to increased rates of nosocomial pneumonia.

The administration of gentamicin at least 1 hour before administration of ampicillin in neonates has been advocated because of in vitro inactivation of aminoglycosides by beta-lactam antibiotics. This method would cause a delay in ampicillin dosing in the treatment of serious bacterial infections and unnecessarily complicate nursing procedures. We studied the effect of varying concentrations of ampicillin (50, 100, 200, and 400 micrograms/ml) on aminoglycosidic antibiotics in vitro with the use of stock solutions diluted in pooled sera obtained from cord blood and incubated samples at 25 degrees C, 37 degrees C, and 40 degrees C. We found inactivation of aminoglycosides to be dependent on time, temperature, and ampicillin concentration, but the degree of inactivation was small and does not support temporal separation of parenteral administration of ampicillin and aminoglycosides to neonates.

We describe an epidemiologic investigation that elucidated the cause of vesicular and bullous skin lesions of the hands and feet that occurred in three otherwise well neonates during a 24-hour period. The investigation encompassed two well-baby nurseries of 28 and 17 beds and one level III neonatal intensive care unit (NICU) of 31 beds located in a 440-bed university-affiliated community hospital. Work-up for infectious causes of the skin lesions in the initial three cases had negative results. Expanded case surveillance disclosed seven additional cases that had occurred within the previous 2 weeks in the NICU. Analysis of risk factors focused attention on the insertion technique for peripheral intravenous catheters. This led to the discovery of a defective transillumination device, the tip of which reached a temperature of 88 degrees C within 20 seconds, causing thermal burns. The cause of the malfunction was the failure to install an infrared filter during the manufacture of the device. No additional cases were observed after the defective unit was removed from service. In summary, a defective transilluminating device caused a cluster of thermal burns in a newborn nursery and NICU. Epidemiologic investigation of the cluster allowed the investigators to focus on techniques of intravenous catheter insertion, which thus led to the identification of the cause of the injuries. With the increasing emphasis on health outcomes measurement, hospital epidemiologists will likely have an expanding role in investigating clusters of noninfectious adverse events.

An elderly woman who had received radiation treatment for carcinoma of the lung presented with erythema, crepitus and pain over the scapular area. Streptococcus pneumoniae was isolated in pure culture from the subcutaneous tissues, and a bronchocutaneous fistula was demonstrated.

In this report, we present a 53-yr-old man with extensive subcutaneous fat necrosis due to acute pancreatitis presenting as fluctuant collections resembling large multiple abscesses. The diagnosis was suggested by examination of the wound aspirate. Findings included absence of organisms on the gram stain, presence of fat globules on wet mount, and an elevated amylase in the wound aspirate. This dramatic presentation preceded any symptoms or signs of overt pancreatitis.

When meningitis presents acutely, therapy should be instituted within 1 hour, based on the patient's age and risk factors. When the presentation is subacute, clinical assessment, with analysis of the cerebrospinal fluid, allows the physician to decide among empiric antimicrobial therapy, observation, or further diagnostic studies.

A patient with debilitating hairy cell leukemia and documented Mycobacterium avium intracellulare infection unresponsive to standard antituberculous therapy who was treated with alpha-interferon is described. A rapid clinical response with correction of underlying pancytopenia and eradication of the atypical mycobacteria infection was found. No deleterious effects from alpha-interferon therapy were found. The associated resolution of anergy and the sterilization of bone marrow suggest that the reversal of host cellular immune defects led to the eventual control of this patient's infection.
